Image display

The cross reference of related application

The present invention comprises the theme about Japanese patent application JP 2004-128945 and JP 2005-43262, and these two patented claims are respectively on April 23rd, 2004 and on February 18th, 2005 applying for that in Jap.P. office their whole contents are included in herein for your guidance.

Technical field

The present invention relates to image display.More specifically, relate to and be used to allow any mobile object of taking to observe as the image display of the image of moving image or rest image as the people of the electric car of advancing in orbit or elevator etc.

Background technology

The electric car passenger a kind of image display and method for displaying image proposed, so that can see moving image (referring to Japanese Unexamined Patent Publication No 2000-172220) by showing the window that the rest image that moving image is divided into a plurality of frames on the display device of settling along the track of train sees through train.

In this case, as shown in Figure 1, image display device is placed on the tunnel wall surface with predetermined space, and its glittering its on its display screen constitutes the rest image of every frame of moving image.Any passenger sees that frame advances image (frameadvanced image) in this train that allows to travel with setting speed.

In order to allow the passenger to regard continuous rest image as moving image, in the situation of film, need per second 24 frames, the NTSC standard is that per second 30 frames or PAL standard are per second 25 frames in the situation of TV.Therefore need per second 24 frames at least to obtain the proper motion image.

For example, show that with per second 30 frames the different interval between the LED display device (liquid crystal display) of rest image is necessary to the gait of march of different electric car 4.If electric car is advanced with the speed of 40km/h, it is spaced apart 37cm, and if advance with the speed of 60km/h, be spaced apart 53cm.

Yet, in the image display that Japanese Patent Application Publication discloses, rest image on the display device of seeing for the window 4a that allows the passenger see through train 4 of settling along the track of electric car 4 is a moving image, is necessary to keep the speed of train 4 to be higher than the speed of setting.

For example, when using 90 width of cloth rest images in 3 seconds, so that the rest image of the per second of seeing 30 frames is when being moving image, the admissible scope of the speed of train 4 is that 50km/h+10km/h is to 50km/h-10km/h.If train 4 gait of march are slower than admissible scope, frame can differently be shown, because be used to show what the image display device of rest image was settled with predetermined interval.In other words, the time period that every frame rest image is shown is longer, or the interval between two frames is long thereby image is discontinuous, looks like factitious moving image.

When the speed of moving object is reduced to half, during 25km/h, the passenger can see 90 width of cloth rest images in 6 seconds.This causes that the passenger in the moving object sees rest image separately off and on, thereby stops him or she to see smooth moving image continuously.

Therefore, thus long fuzzy generation of the time period that rest image is shown, and can not obtain the smooth view of moving image.Can only obtain unsatisfied moving image.This is because if a frame rest image is glittering long-time, and when seeing next frame, according to the spectrum effect of human eyes, this two frame is simultaneously descried, makes image disappear thus, thus the fuzzy image that takes place or see overlapping.

Should be noted that the image of Huo Deing is discontinuous like this, thereby obtains unsatisfied moving image if the demonstration between the rest image is longer at interval.

Therefore, when the gait of march of relative electric car 4 settings of image display device was settled with predetermined space, if the gait of march of electric car 4 changes, it was difficult watching moving image naturally for any passenger.

Therefore, also proposed to be used for image display and its method for displaying image of moving object, so as the stable image of a frame show can moving object along the image display of settling partly by the time all time periods carry out (referring to Japanese Unexamined Patent Publication No H11-202818) according to the travelling speed of moving object.

In this case, the sequential that is used for display image display device rest image is based on and is installed in speed that first speed detector near display device array top obtains and is controlled by the speed that the second speed detecting device that is installed near display device array tail end obtains.

This sequential that allows to be used to show rest image is controlled by the speed of moving object in nearly all time period of the image display part of settling according to moving object.Even moving object changes travel speed in the way of the part by the image display settled, also can show rest image on image display, thereby make that personnel stably see in the image passive movement object with its corresponding sequential.

If, yet, when the part of moving object by the image display settled, moving object (is for example travelled with the speed more much lower than supposition speed, the Half Speed of moving object travel speed 25km/h), just is difficult to stably show that rest image is on display device.Replacedly, if moving object is travelled with the speed more much higher than supposition speed, be difficult to also stably show that rest image is on display device.

Further, as shown in Figure 1, rest image is necessary to distribute to each image display device 10 with the signal that is used for flash of light (light transponder pulse), and this image display device 10 is fixed in the wall surface 5a in tunnel 5, and they go up alignment with predetermined interval at the direct of travel " a " of electric car 4.Therefore, image display device 10A, 10B ..., 10N is with two communication paths, as the datagram that is used to distribute rest image is as path (communication cable) 9a be used to distribute the communication path 9b of flash pulse connected to one another.

Communication path based on the Carrier Sense Multiple Access (CSMA/CD) of being with collision detection in Ethernet, can not guarantee real-time response or tautochronism (isochrony).If be assigned to display device 10A, 10B ..., the rest image of 10N (as one man) simultaneously glistens and can not they be glistened, and the image of demonstration rocks, and therefore produces unsettled display image.

Therefore, except being used to distribute the communication path 9a of rest image, also providing the communication path 9b that is used to distribute flash pulse.For example can use, the communication cable that can be connected by Ethernet according to transmission control protocol/Internet protocol (TCP/IP) is as data communication path 9a.Can use communication cable, as RS 485 cables that can connect by Physical layer and can be connected by multiple spot, as the communication path 9b that is used to distribute flash pulse.

In the image display in the past, need two kinds of communication paths (communication cable) so that they are connected to each other.This causes the communication path setting operating difficulties.In practice, need 90 to 120 switching hubs to connect their with cascade form and form star and connect, the parts that are used to connect them so also are necessary, therefore increase its cost.

According to the further embodiment of the present invention, provide a kind of image display to be used to provide moving image, this moving image is by obtaining with the at interval glittering rest image of preset time along the path of moving object, thereby the personnel that allow to take this moving object can see the moving image by static generation.This equipment has the display device that comprises a plurality of display units, and this display unit is aligned along the path of moving object and does not have any interval therebetween.This display unit is positioned in a plurality of places that the personnel that take moving object are allowed to see from moving object display unit.

This equipment also has feeding mechanism and is used for supplying the picture signal of a plurality of rest images that constitute moving image to display device.This equipment further has display control unit, and it is used for controlling display device with the sequential set with their respectively with at the setting position of display device, shows a plurality of rest images based on the information of setting the travel speed of moving object about the front.

According to another embodiment of the present invention, a kind of method for displaying image is provided, it is used for being used for showing that the display device of moving image shows moving image, and this moving image is to obtain by picture signal to the display device of supplying a plurality of rest images that constitute moving image.This display device comprise a plurality of moving objects of taking along personnel the path alignment and therebetween without any display unit at interval.The moving image that these personnel that allow to take moving object can watch rest image to produce.This method comprises the steps: to obtain the travel speed information of moving object and based on the travel speed information of the moving object of such acquisition, sets sequential with it and show a plurality of rest images, be shifted the to each other distance of its setting of image.

In according to these embodiment of the present invention, a plurality of display units are positioned in the position that the personnel that advance by moving object are allowed to watch from moving object display unit, and wherein display unit is aligned along the path of moving object and therebetween without any at interval.Further, based on the travel speed of moving object, display control unit control feeding mechanism shows a plurality of rest images to set sequential by them respectively at the desired location of its display device.Therefore, when display image, obtain moving object travel speed information and based on the travel speed information of the moving object of such acquisition, a plurality of rest images are set sequential by their respectively and are shown, image its setpoint distance that is shifted each other wherein.

This make when moving object is slowly travelled, can only work as when moving to its appropriate location with its suitable speed could descried second or more the rest image of back be shown.In this case, the second, the three ..., n rest image shown respectively when first rest image draws at them.Because the relative turnover speed of moving object is increased, if the moving object low running speed, can carry out moving image that rest image produces steadily and the view of nature.

Based on the travel speed of moving object to definite permission of the display position of each rest image that will be shown to moving object from a slow speed can both be corresponding to speed widely at a high speed.This also allows to carry out stable image demonstration, even the travel speed of moving object changes in the image display part of settling.

Because a plurality of display units that align along the path of moving object are continuously location, can arbitrarily adjust the width of the rest image that will be shown, thereby relax restriction, and permission can both be corresponding to video standard signal and wide picture signal to the rest image width.

Replacedly, be necessary to provide a kind of image display, it can be used to distribute by a communication path information and the light emission information of rest image.

According to embodiments of the invention, provide a kind of image display.This image display has a plurality of display device, each display device has through (pass-through typed) interface section, with a pair of system control device, each is used for distributing each to a plurality of display device of the rest image that constitutes moving image at least.Note to be called as " through interface section " below the interface section that any information can unidirectionally pass through.System control device is positioned in the initiating terminal of these a plurality of display device and finishes end.These a plurality of display device and system control device are to link each other by daisy chain, and through interface section is penetrating under (cut-through) operating conditions with the delay element that fixes.

In according to embodiments of the invention, the therebetween positioned at intervals of a plurality of display device to set.As an example, adopt seamless system so as to comprise the image display part alignment of LCD (LCD) and adjacent components between without any at interval.These display device are fixed to, for example any position of tunnel wall surface.These surface of position are to the moving object by the tunnel, as mentioned above.This system control device also is positioned at the initiating terminal of these a plurality of display device arrays and finishes end.These a plurality of display device and system control device are connected to each other by chrysanthemum chain communication path (for example, communication cable such as 1000Base-T cable).

This system control device distributes rest image to each display device.Simultaneously, it also distributes the light emission information about display device.Each system control device provides detecting sensor, and it is used to detect the travel speed of moving object.The light transmission interval of display device (flash of light sequential) is based on detected like this speed output calculating.

Each display device has through interface section so that keep the real-time response of the information of the distribution that keeps and to allow display device be the chrysanthemum chain, thereby reduces communication path to.

Through interface section has two or three ports.With reference to having the interface section of two ports, when having determined that the information that receives at port is not in the time of will arrive the display device of himself, through interface section as delay element in case the information that in statu quo sends reception to the another port.In other words, through interface section penetrate under the operating conditions as (as) fixing delay element.

Therefore, if the information of distributing will arrive the display device of himself, this display device receives this information.Yet if the information of distributing is not to arrive the display device of himself, this information just in statu quo is sent to output port from input port.In other words, if the information of distributing is not the display device with respect to himself, through interface section is only as delay element.Fix its time delay.Therefore, by using this two ports, allow two-way communication (full duplex transmission).

When be Dn fixing time delay, when moving object is with the equation calculating of m*Dn from first display device the total time delay by m device shown.By glittering (illuminating) display device simultaneously as one man, the passenger in the moving object can watch moving image or rest image.In order to use flash of light simultaneously, common light transmit (pulse signal) be dispensed to simultaneously to come to this in a plurality of display device and each display device and distributed, control flash of light be so that light emission signal can be delayed total delay time, and total delay time is exactly the time period that arrives the display device of himself from the time period that display device receives light emission signal to light emission signal.In this case, first display device that light emission signal at first is dispensed to (just, apart from distributing the nearest display device of side system control device) have the longest stand-by period, waiting time is time period to the photoemissive time period that receives light emission signal from it.Be positioned near the system control device of receiver side last display device and have 0 or stand-by period of Dn minute.

By considering such time delay (light emission stand-by period), it is irrelevant with its number so that they glisten simultaneously to control a plurality of display device, thereby keeps the real-time response of information and keep its tautochronism.Because if the information that receives at port is essential to the display device of himself, it is acceptable then distributing, but if not, the information that receives at port is sent to other port same as before, information and light emission information about rest image can be dispensed to all a plurality of display device by a communication path, and this communication path is the chrysanthemum chain.

As the prerequisite of distributing about the information of rest image etc., in carrying out the moving image processing procedure (in assigning process), total system is initialised and different types of processing of being used for acquired information is performed.

As initialization, can carry out identification and handle, this processing is used for its sign is applied to each of a plurality of display device.This equals to use media interviews control (MAC) address in wherein.Especially, MAC Address is available to the image display of the through interface section that includes three ports.In the image display that three ports are arranged, a port is connected to CPU board etc., so that except being applied to the IP address of CPU board, MAC Address also can be used, thereby allow display device and system control device and another network service, use these addresses to connect with respect to this network of system control device.

According to an alternative embodiment of the invention, use the User Datagram Protoco (UDP)/Internet protocol that can be used for real-time response (UDP/IP) as the transport layer in the Ethernet.Command information packed (capsuled) of multiple necessity and encapsulated information are inserted in the head of the Payload that udp protocol generates in the information of initializing set and certain operating process.Polytype command information is shown among Figure 20, and it will illustrate in the back.As one of them, the display device search command can be used, and this order is used for searching for display device.When the order that is used to search for display device is inserted into, is used for the optional data that the user of display device sets and only is inserted into the data division of Payload, thereby generate control frame by the display device that will be shown with command information.

Therefore, in according to this embodiment of the present invention, the required multiple information (command information etc.) of display image be inserted into the UDP Payload the head in (through frame head).The frame form that the data that wherein are used for display device etc. are inserted into the Payload main body may be utilized.

This allows datagram even is handled with the hardware and software that general T CP/IP protocol stack is arranged, thereby keep the existing Ethernet and the compatibility of ICP/IP protocol, this datagram will self be translated by through interface section (interface section of describing later with three ports).

According to further embodiment of the present invention, the such data that are used for display device then are linked to the number of hops (number of hops X) of head.If number of hops X is Xi when the display device received signal, is used for i of display device data Di that inserts and is used as the part of the MAC Address that is used for himself display device and is saved.Just, the data Di that is used for display device is used as the part of MAC Address.

Number of hops Xi increase by 1 is Xi+1 when display device sends out the signal of reception, and number of hops Xi new settings is Xi+1.Be used for i+1 of display device data Di+1 that inserts and consulted and be saved a part for the MAC Address that is used for this display device.

Therefore, in the initializing set stage, replace the data of the sequence number that constitutes MAC Address, the user's setting data D (about 3 bytes) that is used for display device is used, it just is used as the part of MAC Address, so that can individually and/or independently be set at the MAC Address of display device.This allows to be avoided the relation with display device.If display device is changed or variation recently, new MAC Address can easily be applied to total system.

As the processing of acquired information in its operating process, the status information of light emission situation, internal temperature, the operating conditions of display unit etc. is can be conceivable.The processing that is used for acquired information like this can be carried out by inserting the information gathering order, this information gathering order is used for the head of information gathering to Payload, and the number of hops X of this Payload is updated and condition information is inserted into the data division of Payload by each display device of sending Payload.

According to embodiments of the invention, a plurality of display device and system control device are each other by the daisy chain link, and the through interface section that provides for each display device penetrates under the operating conditions with the delay element that fixes at it.

Therefore, since display device can keep its real-time response only with the delay element that fixes.Because fixing time delay, if consider and control light emission sequential from the time delay that first display device occurs to the display device of himself, the a plurality of display device of may command are so that their consistent flash of lightes simultaneously, thereby keep the light tautochronism of launch time.

If the information that through interface section determine to receive is arrive the display device of himself, it is as delay element, is actually in the information of port reception by it to send out from other port.Each port is as input port and output port, so that a plurality of display device and system control device can be connected to each other by the daisy chain type communication path.

This makes the number of communication path can be reduced 1.The required number of display device can be not use any parts, as the daisy chain type that switches hub, thereby simplifies setting operation and reduces the cost of parts.

Use the communication cable of right price, as available relatively 1000base-T cable, allow expensive performance, message capacity increases, and the expansion of display device purposes realizes easily.

The conclusion part of this instructions particularly points out and directly requires purport of the present invention.Yet by reading the part of this instructions remainder with reference to the accompanying drawings, those skilled in the art will understand the tissue and the method for operation of the present invention best, with and further advantage and purpose, same label is meant same element in the accompanying drawing.

Fig. 6 illustrates the example of program inventory.These programs comprise multiple rest image, and as the television commerce image, movie preview, and advertising image are as the promotional video image.Fig. 6 illustrates a plurality of programs that conceptually are stored among the RAM 22.When a plurality of program storage during at RAM 22, the rest image as the advertisement for cosmetics image for example is stored in the program address 01, as shown in Figure 6.Similarly, the rest image as the image of car amount advertisement is stored in the program address 02.Further, in example shown in Figure 6, as hamburger, whiskey, cigarette, the rest image of the image of electrical equipment advertisement is stored respectively at program address 03,07, in 08 and 09.

Can set and how optionally store them.Below such situation will be described, wherein they are stored with image-input device 33.The rest image as the image of advertisement for cosmetics with predetermined frame is at first caught from image-input device 33, and is stored among the RAM 22 and is assigned with address 01.Then, catching from image-input device 33 as the rest image of car amount advertising image of predetermined frame arranged, and be stored among the RAM 22 and be assigned with address 02.According to similar process, the rest image with remainder of predetermined frame is caught from image-input device 33, and is stored among the RAM 22.

Below, the inventory of the program of storage as shown in Figure 6 is called as " program inventory ".Program display unit 31 or display unit 32 can be used as monitor display program inventory so that confirm as required.

Fig. 7 illustrates such situation, and wherein a frame rest image is shown on the LCD device.For example, if the width of the LCD device of display device 11 is 47 centimetres, when a frame rest image was shown on the LCD device, the speed of electric car 4 was that 50km/h is so that per second shows 30 width of cloth rest images.This speed is set to the reference velocity that is used to explain.

As shown in Figure 7, if electric car 4 travels with reference velocity, the rest image of frame F1 is shown on the LCD device 11-1; The rest image of frame F2 is shown on the LCD device 11-2; The rest image of frame F3 is shown on the LCD device 11-3; Be shown on the LCD device 11-n with the rest image of frame Fn.Therefore, with 30 LCD device 11-1,11-2 ..., 11-n shows 30 width of cloth rest images.

Fig. 8 illustrates such situation, if wherein electric car travels with half of reference velocity, shows rest image.If electric car 4 is with Half Speed, 25km/h travels, and the rest image of frame F1 is shown on the LCD device 11-1.Half shows LCD device 11-1 the rest image of frame F2, and half is shown in LCD device 11-2, so that it can use the position display with the frame F2 of frame F1 displacement field.Similarly, the rest image of frame F3 is what to use with the position display of the frame F3 of frame F2 displacement field.Therefore, 30 width of cloth rest images are with 16 LCD device 11-1,11-2 ..., 11-n shows.

Fig. 9 is the view of the such situation of explanation, if wherein electric car travels with the twice of reference velocity, rest image is shown.If electric car 4 is with the twice of reference velocity, the speed of 100km/h is travelled, and the rest image of frame F1 is shown on the LCD device 11-1.The rest image of frame F2 is shown on the LCD device 11-3.Similarly, the rest image of frame F3 is shown on the LCD device 11-5.

In this case, notice that the interval that a plurality of rest images can be scheduled to shows, as be shown in the image display 1 among Fig. 1, the display device of wherein passing by is with predetermined interval alignment.

Figure 10 illustrates the relation between the speed and display position when showing rest image with per second 24 frames.In Figure 10, the viewpoint on image display device 11 illustrates, and illustrates the DISPLAY ORDER and the display position of every frame rest image.The display position of every frame rest image when Figure 10 A explanation is travelled with 50km/h when electric car 4., note each LCD device 11-1 herein, 11-2 ..., the width of the display screen of 11-n is 55 centimetres.The display position of every frame rest image when Figure 10 B explanation is travelled with 10km/h when electric car 4.

Shown in Figure 10 A, if electric car 4 travels with 50km/h, frame F1, F2 ..., the rest image of Fn is shown in LCD device 11-1 respectively, 11-2 ..., on the display screen of 11-n.In this situation, by the speed calculation based on electric car 4, the display position of every frame rest image is shifted 55 centimetres each other.The rest image of every frame is shown and without any at interval and any overlapping.Therefore, with 24 LCD device 11-1,11-2 ..., 11-n shows 24 frame rest images.

Shown in Figure 10 B, if electric car 4 travels with 10km/h, calculate by travel speed based on electric car 4, the display position of the rest image of every frame is shifted 11 centimetres each other, so that the rest image of every frame overlaps.Herein, in order to explain, display panel 40 does not have normal width, and for example width is 88 centimetres.If LCD device 11-1,11-2, ..., 11-n has the width of 88 centimetres display screen, and the frame width also is 88 centimetres, and the rest image of frame F1 is shown on the LCD device 11-1, then, the rest image of frame F2 is shown, and the travel direction of the relative electric car 4 of its rest image with frame F1 is shifted 11 centimetres.In this moment, the rest image of F2 is shown in LCD device 11-1,11-2 ..., on each parts of the display screen of 11-n.

Behind the rest image of display frame F2,11 centimetres of the rest image of the rest image of frame F3 and frame F2 displacements and being shown.At this moment, the rest image of frame F3 is shown in LCD device 11-1, on each parts of the display screen of 11-2.Therefore, when showing F2 to the rest image of F8, the LCD device is driven simultaneously to show them.

At the rest image that shows F8 in LCD device 11-1, on the display screen of 11-2 after, the rest image of frame F9 is shown on the display screen of LCD device 11-2, it is positioned in end 88 centimeters apart from LCD device 11-1.When the rest image of display frame F9, only LCD device 11-2 by the zone to show it.Further, as display frame F10 during to the rest image of F16, LCD device 11-1,11-2 is driven simultaneously to show them.When the rest image of display frame F17, only LCD device 11-3 is actuated to show it.As display frame F18 during to the rest image of F24, LCD device 11-3,11-4 is driven simultaneously to show them.Therefore, the contiguous LCD device in the left side showed rest image before 8 frames.The rest image of 24 frames is with 4 LCD device 11-1,11-2, and 11-3 and 11-4 show.

If therefore electric car 4 low running speeds show that the rest image that is shifted allows them to show with identical frame rate.

Should be noted that if electric car 4 travels with 100km/h, be shifted 100 centimetres relative to each other by the display position that calculates every frame rest image.When frame width during less than 110 centimetres, the rest image of every frame is shown so that they are separated from each other.

The width of the image that is shown (width of picture frame) can arbitrarily be set.As mentioned above, the travel speed of the width of the display position of image and image and moving object (taking the personnel of this moving object) is relevant.Herein, the width of panel of travelling is set to Wp, and the width of the image of demonstration is set to Wv, and the travel speed of moving object is set to Vt, the light transmission interval of backlight is set to Tf, and the operating range of moving object (taking the personnel of this moving object) is set to Sts.

The operating range of moving object (taking the personnel of this moving object) is set to Sts and obtains according to expression formula Sts=Vt*Tf.If operating range Sts is greater than the width of the image that shows, Sts＞Wv, image show with predetermined sequential, come so that they are shifted each other with predetermined interval.If the width of the image that operating range Sts equals to show, Sts=Wv, display image is so that they are adjacent.If operating range Sts is less than the width of the image that shows, Sts＜Wv, display image so as their adjacent and displacements come.

The composition number of the image that shows (divided number) Nd obtains according to expression formula Nd=Wp*Sts.

Increase if form number, this is corresponding to the situation of electric car fast running.Yet if the electric car fast running, the incremental data that be stored in the image storage part spare 48 also increases.This capacity that causes image storage part spare 48 also will be increased.

Fig. 1 illustrates the example of display sequence.In this case, the width of display panel Wp equals the width of display image Wv.The composition number N d of the image that shows obtains according to expression formula Nd=6*Sts.

The physical alignment of Figure 11 A explanation display panel.The number that illustrates is the number of the frame that will show.Content displayed during Figure 11 B description time 0.Frame F1, F2, the rest image of F13 and F19 is presented at respectively on their display panel.Take the image that personnel that moving object travels watch frame F1.The content of the time showing after Figure 11 C description time Tf is over and done with.At this moment, frame F2, F8, the rest image of F14 and F20 is by on the display panel that is shown in them respectively.Take the image that personnel that moving object travels watch frame F2.The content of the time showing after Figure 11 D description time 2Tf is over and done with.At this moment, frame F3, F9, the rest image of F15 and F21 is by on the display panel that is shown in them respectively.Take the image that personnel that moving object travels watch frame F3.The content of the time showing after Figure 11 E description time 3Tf is over and done with.At this moment, frame F4, F10, the rest image of F16 and F22 is by on the display panel that is shown in them respectively.Take the image that personnel that moving object travels watch frame F4.The content of the time showing after Figure 11 F description time 4Tf is over and done with.At this moment, frame F5, F11, the rest image of F17 and F23 is by on the display panel that is shown in them respectively.Take the image that personnel that moving object travels watch frame F5.The content of the time showing after Figure 11 G description time 5Tf is over and done with.At this moment, frame F6, F12, the rest image of F18 and F24 is by on the display panel that is shown in them respectively.Take the image that personnel that moving object travels watch frame F6.The following demonstration time is similar to the situation among Figure 11 B.Take the image that personnel that moving object travels watch frame F7.Therefore, top content is repeated to show.With 5 LCD device 11-1,11-2,11-3,11-4 and 11-5 show the rest image of 24 frames.

As shown in figure 11,2 to 12 totally 11 frames be illustrated as the frame that will on LCD device 11-2, show.Except the image of display frame F7, the view data of synthetic two frames to generate a synthetic signal so that image can be with this signal demonstration.For example, at time T f, the view data of frame F2 and F8 is synthesized and generates synthetic signal so that image can show with this signal.Therefore the storage 2 to 12 of the image storage part spare 48 of LCD device 11-2 totally 11 frame image datas.

8 to 18 totally 11 frames be illustrated as the frame that will on LCD device 11-3, show.Except the image of display frame F13, the view data of synthetic two frames to generate a synthetic signal so that image can be with this signal demonstration.Therefore the image storage part spare 48 of LCD device 11-3 8 to 18 totally 11 frame image datas temporarily.Other LCD device is also strict similar.Note the image storage part spare 48 of LCD device 11-1 can temporary storage 1 to 6 totally 6 frame image datas.

The operation of image display 100 is described below with reference to the accompanying drawings.Figure 12 description of flow diagram, the processing operation of this process flow diagram indication when rest image shows in image display 100.

As shown in figure 12, at step S1, when rest image is shown in the image display 100, program inventory #N (N=1,2 ..., N) at first be buffered 24 storages.For example, the picture material of program inventory 01 is stored in wherein.

At step S2, determine whether detecting sensor 13a detects the existence of electric car 4.If detect the existence of electric car 4, process forwards step S3 to, obtains the velocity information of electric car 4 at this.At this,, speed detection sensor 13b obtains detection speed thereby detecting the travel speed of electric car 4.At step S4, the display position of the image that calculating will be shown.Herein, CPU 21 calculates the display position of each image based on the travel speed of the electric car 4 that detects.

At step S5, buffer memory 24 is operated so that at each LCD device 11-1,11-2 ..., the suitable position display picture signal of the display screen of 11-n.At step S6, determine whether that electric car passes through.If pass through, process forwards step S7 to, and CPU 21 stops the operation of buffer memory 24 herein.If S6 does not pass through in step, process forwards step S3 to, repeats top operation herein.

Then, if determined to continue image display mode at step S8, process forwards step S9 to, and program inventory increases by 1 herein, and process rotates back into step S1 then, waits for image display operations herein.

Finish at step S8 if determined image display mode, this image DP display processor stops.Therefore, whenever electric car in image display mode passes through, program inventory is updated.This allow display image program whenever electric car by the time rewrite automatically.According to the program mode of any transmission program, the transmitting time that be provided with each program of the personnel that travel by moving object can be identical.In this case, this can realize in 0 to 100km/h travel speed scope at electric car 100.

Figure 18 illustrates the notion of through interface section 240.Through interface section 240 has at least two ports.Figure 18 illustrates the through interface section 240 with two ports.These through interface section 240 usefulness with two ports act on the delay element of transmission information, this information be penetrate operation constantly when determining that the information that receives will not arrive himself display device from a port reception.In other words, through interface section 240 is as penetrating operation fixing delay element constantly.

In having the through interface section 240 of two-port, if port (I/O part) 242 is operated as input port, other port (I/O part) 244 is operated as output port, if and other port 244 is as input port operation, a port 242 is operated as output port.This makes alternately, and (full duplex) communication can realize that so that there are two disposal system 250A and 250B in through interface section 240, they have identical configuration.

If a port 242 is operated as input port, the control frame information that receives at this port 242 is provided to the test section 252A of matching addresses, and the test section 252A of this matching addresses constitutes disposal system 250A is inserted into the address (header) in the control frame with detection coupling.The address that is used for himself display device is given when system initialization, and this will illustrate below.

If the address of himself display device of the matching addresses that receives, control frame information is transferred to next frame read/write part 254A, and is analyzed in this information.Typical processing will illustrate below.

At first, if the result who analyzes indication writes processing, then necessary frame information is written in the image frame buffers 260.

Secondly, if the pilot light of analyzing as a result emission deferred message, then deferred message is stored in the light emission control part 262.Though only operate as delay element through interface section 240, it can know the time delay of the display device 11i (any number that the i indication is selected) of reception from 1 to N, if calculate from first display device 11A, when the display device 11i that find to receive be which when installing, be that as one man glittering at one time display device 11 is necessary this time delay.This system control device 300A calculates the time delay of the display device 11i that receives, and distributes the delay time information as result of calculation.This light emission control part 262 is preserved this delay time information of distributing to himself display device then.

The 3rd, if the processing that the result who analyzes indication is read from frame buffer 260, then necessary information is read from frame buffer 260, and the information that reads is added to the zone corresponding to control frame.

Error-checking coded portion (Frame Check Sequence (FCS)-generation part) 256A miscount check code, for example, the Cyclic Redundancy Check code is so that the code that calculates adds control frame to.

The 4th, if system control device 300A collects the status information of display device 11A, the information that is kept at status surveillance part 264 is inserted in the control frame and is sent out.In this embodiment, supply through entry terminal 266a from the temperature information of display device 11A internal temperature sensor (not shown).Further, in this embodiment, supply through entry terminal 266b about the display message whether flash of light is carried out.

Therefore, in this embodiment, temperature information and display message are supplied to system control device 300A through system control device 300B.Sending and/or receive and handling is to carry out with communication cable 241 ', and this cable directly is connected between system control device 300A and the 300B.

In the superincumbent processing, do not find to be used for the display device of himself in control frame, the frame of read/write part 254A and FCS generation part 256A becomes to penetrate to be operated so that the information that receives is sent out output port (I/O part) 244 and does not increase any processing.Therefore, disposal system 250A is only as delay element.Configuration according to disposal system 250A is different time delay with clock frequency.For example, clock frequency is 250MHz, and disposal system has 10 stage pipeline structure, is about for 400 nanoseconds time delay.Frame buffer 260 is preserved this delay time information.

In disposal system 250B, I/O part 244 is as the input port operation, and I/O part 242 is operated as output port.Disposal system 250B has the configuration identical with disposal system 250A, and carries out identical processing.Therefore, corresponding digital and character (252B is to 256B) are applied to corresponding part, and its operation instructions etc. is omitted.

In order to carry out top operation, the frame structure of the control frame shown in Figure 19 A and 19B is adopted by embodiments of the invention.Such control frame comprises head and Payload, and tail (trailer).

Be added to the top of control frame by a plurality of the heads that constitute.Head comprises Ethernet head, IP head and UDP head.

First stature is the Ethernet head.The Ethernet head is for distributing necessary information to system control device 300B to provide through a plurality of display device 11A to 11N from system control device 300A.Similarly, the Ethernet head also is for distribute necessary information to provide from system control device 300B to system control device 300A.

Therefore, send, be inserted in the Ethernet head as the MAC Address of the system control device 300A of transmitting terminal with as the system control device 300B of receiving end if data are system control device 300B.This data structure is used in the situation that electric car 4 travels along the arrow shown in Figure 14 " b " (for example, to the direction of reaching the standard grade).The Ethernet head has 14 bytes.

If data are system control device 300A and send, be inserted in the Ethernet head as the MAC Address of the system control device 300B of transmitting terminal with as the system control device 300A of receiving end.This data structure is used in the situation that electric car 4 travels along the arrow shown in Fig. 1 " a " (to the direction that rolls off the production line).

Adding the IP head of 20 bytes be used to discern hardware, is thereafter the Ethernet head.The IP head comprises the IP address of system control device 300A and 300B.In the IP head, data receiver " a " direction or " b " direction above being according to whether, the IP address of transmitting terminal and receiving end exchanges each other.

If network structure is closed, as shown in figure 15, the IP address is always not necessary.This is because if hardware does not have the IP address, and hardware can be only with its MAC Address identification.In the frame format shown in Figure 19 A, consider the connection of another network and wherein the back mention CPU etc. and can be fixed to display device from the situation that through interface section on one's body is used, the head that wherein can add the IP address is provided.

Adding the UDP head, is thereafter the IP head.In this embodiment,, consider its real-time characteristic, adopt the UDP/IP agreement about ethernet communication protocol.As the UDP head, the port number (optional) of transmitting terminal and receiving end is identical.

The Payload that actual information is inserted into wherein comprises frame head and Payload main body.The structure of frame head can be set voluntarily by the user.In this embodiment, shown in Figure 19 B, frame head comprises the pattern part, number of hops part, command component, index part and image information part (two parts).Each part all has two bytes.

The version information of control frame is added to the version part.Number of hops is partly by upgrading the each increase by 1 of number of hops whenever by display device 11 time. System control device 300A and 300B can be based on the numbers of knowing the display device 11 that is connected between system control device 300A and the 300B as its number of hops X during by last display device 11N.If number of hops X is stored in each display device 11, they can find that it is that this display device 11 begins from first display device for which device, thereby used as the identification information of display device.For example, when X=1, expression formula X=i is stored in i the display device, so that this display device can know that it is an i display device.The initial value of number of hops X is set to 0.

The command information that is used for fixing this control frame execution how many kinds of processing is inserted into command component.Figure 20 explanation is according to the embodiment of command information of the present invention.

Command information comprises and is used to allow any display device 11 initialized initialization commands (No.1), be used for distributing one by one MAC Address defined by the user order (No.2) (display device search command) to each display device 11, be used to distribute the image data transmission order (No.10) of Still image data and be used to launch the light firing order (No.7) (flashlamp order) of light emission signal to each display device 11.

Command information also comprises collects order (N0.3) time delay of the time delay that is used to collect each display device 11, light emission monitor command, and the temperature monitoring order is used to monitor the status surveillance order of each display device 11.The user can arbitrarily set a kind of order.

With reference to the control frame that is shown among Figure 19 B, the index part of Payload head is used to discern specific display device 11i.If the user wants to send Still image data to specific display device 11i, he or she can discern number of hops by index part.This is corresponding to specific display device 11i because of number of hops X.

Image information partly has 4 bytes.In the payload format shown in Figure 19 C (B), be used for indicating the numeral (indicating which frame) that sends the rest image number of pages and be used to stipulate which horizontal line of this frame inserts (page or leaf/wire size) as the information of two bytes.This is because rest image has bulk information, so it is divided into two parts and sends, and this will illustrate below.Be used to indicate the information of back to back two bytes of total transmission row to be inserted into.

If not the image data transmission order (No.10) that is used for transmit image data, this image information of 4 bytes partly is as the blank of the payload format (A) shown in Figure 19 B, does not have data to be inserted into.

In this embodiment, prepared the main body of the data of 1472 bytes as Payload.If suppose about 120 display device 11 of total number as mentioned above, guaranteed that the data of q.s are handled by these bytes.

In this embodiment, information is inserted by 4 byte units.The data division of these divisions is relevant with number of hops X respectively.For example, if being the information of 0, the first data division, number of hops X is inserted into relevant with it.If number of hops X is " i ", the information of i+1 data part is inserted into relevant with it.The information of inserting is based on the command information change.If view data can be utilized in the information of all 1472 bytes.

The configuration of control frame when order is inserted is described below with reference to the figure of Figure 21 or back then.Attention system control device 300A installs in transmission ends, and system's control is advocated peace and installed at receiving end from 300B.

Figure 21 A is inserted into and the configuration of MAC Address used control frame when being assigned to each display device 11A to 11N when the display device search command to 21H explanation.Shown in Figure 21 A, the default value of number of hops X is set as 0.In the head of Payload, number of hops is set as X=0, and then, the display device search command is inserted into.Remaining part is that blank or nonsignificant data are inserted into wherein.#1 by the random display device of setting with 3 bytes of user is inserted into the Payload main body to #N item number certificate.

Pei Zhi control frame has the non real-time response like this, so that control frame can generate in data processing section 322.The control frame that generates is through transmission buffer 332, and output switch 334 and I/O part 324 send to display device 11A (referring to Figure 17).

Display device 11A executive address detects.In this embodiment, mention number of hops X for this reason.If number of hops X coupling with himself display device, Payload main body about this number of hops X is mentioned, so that the corresponding data #1 of display device is used as the part of the MAC Address of display device 11A, as himself display device (referring to Figure 21 B).For example, 3 bytes (byte number that is used for sequence number) of the least significant bit of MAC Address (LSB) are rewritten as the corresponding data #1 of display device.The MAC Address of rewriting is stored.Matching addresses test section 252A stores it.

Then, number of hops X increases by 1, and it is sent to other output port 244 (referring to Figure 21 C) then.Because in contiguous display device 11B, number of hops X is updated, display device 11B can know that this and display device 11B self is relevant.The part MAC Address is rewritten as the data #2 of the display device 11B relevant with number of hops X=1.The MAC Address of rewriting is stored (referring to Figure 21 D).Number of hops X is updated then, promptly increases by 1 (X=2 just).The frame that upgrades is sent to other output port 244 (referring to Figure 21 E).

Such reference process of number of hops X (matching addresses testing process), the preservation process of the corresponding data #i of display device, the part of MAC Address rewrite process and the preservation process is carried out in 11N (referring to Figure 21 F and 21G) at all display device 11A.System control device 300B receives the control frame (referring to Figure 21 H) of the number of hops X with latest update.System control device 300B returns the system control device 300A of the control frame of reception to transmitting terminal.

In its result, system control device 300A and 300B can know the setting number of display device 11.The automatic distribution and the preservation process of MAC Address are finished at this moment.

Therefore, separately and the setting that is independent of the MAC Address of display device avoid with reference to any display device.If display device is exchanged or installation newly, this allows new MAC Address easily to be dispensed to display device.

If the situation of MAC Address as display device 200, then takes place to use in the network figure of closure only as shown in figure 15.Yet through interface section 240 has 3 ports, and it will illustrate below that a port is connected with CPU board.If like this, MAC Address can be used to discern CPU board.Replacedly, when the network that constitutes this through interface section 240 was connected with another network and is shown from the view data of another network, the MAC Address of single application was used.

The configuration of the control frame that Figure 22 A uses during the time to the inherent delay of 11N as each display device of measurement 11A to 22H explanation.This control frame also has the non real-time response.

Shown in Figure 22 A, number of hops X is reset to 0 and set the order (delay time measurement order) be used to collect time delay.Remaining part is blank.Therefore, the Payload main body also is blank.This system control device 300A emission control frame.First display device 11A receive it (referring to Figure 22 B).

Because the number of hops X of first display device 11A is 0, display device 11A determines that this number of hops X will arrive display device 11A self.Display device 11A analyzes the delay time information of order and reading displayed device 11A to set it to corresponding data division, as the data #1 (referring to Figure 22 B) of display device 11A.Then, number of hops X increase by 1 also is sent to other output port 244 (referring to Figure 22 C) then.Contiguous display device 11B analyzes the number of hops X of reception so that display device 11B determines that it will arrive display device 11B self, thereby analyzes order (referring to Figure 22 D) similarly.Because it is the order of the setting of delay time information,, display device 11B is written into the data #2 (referring to Figure 22 D) of corresponding data division as display device 11B thereby reading its delay time information.Number of hops X is updated and sends (referring to Figure 22 E) simultaneously.

Carry out such analysis of number of hops X and order, delay time information write (settings) processing display device 11N (referring to Figure 22 F) to the last.Last then display device 11N write latency temporal information, and number of hops X is updated and sends (referring to Figure 22 G).System control device 300B reception result also is back to system control device 300A (referring to Figure 22 H) with it.This process makes all display device 11A to collection and the preservation of 11N with the end delay time information.

System control device 300A and 300B calculate and store the light dead time of each display device 11A light emission control part 262 in the 11N.If the n item of display device 11 all is set, for example, the light dead time D1 of first display device 11A is D1=(n-1) * Dn, and wherein Dn indicates the inherent delay time of first display device 11A.Similarly, the light dead time Dn of last display device 11n is 0.

Therefore, display device 11A is to the 11N emission light that can stagger their intrinsic time delay if every smooth dead time all is set, and display device 11A can be at the same time as one man by glittering (flashlamp illuminates) to 220N to the display unit 220A in the n item of 11N.

The control frame of Figure 22 is used to collect various states information, as light emission monitor message, temperature monitoring information and display device status surveillance information.Each of these control frames all has the non real-time response.

Be assigned to each display device 11A based on the light dead time information of calculating to the deferred message of 11N about each display device 11A of collecting like that as shown in figure 22 and launch information as light to 11N.Figure 23 illustrates the configuration of control frame in this situation.Control frame has real-time response.Be shown in this control frame of generation of the real-time processing section 330 among Figure 17.

In this control frame, number of hops X is reset to 0, and the light firing order is set as an order (referring to Figure 23 A).In the Payload main body, corresponding to the data division of each display device 11A to 11N, the light dead time information of calculating ((n-1) * Dn, (n-2) * Dn ...) every being set.System control device 300A launches this control frame.First display device 11A receive it (referring to Figure 23 B).

Because the number of hops X of first display device 11A is 0, display device 11A determines that it will arrive display device 11A self.Thereby display device 11A analyzes order and is written into light launch control unit 262 with reference to the light dead time information of number of hops X reading displayed device 11A and at this it is preserved from corresponding data division.

Then, number of hops X increases by 1, and is sent to other output port 244 (referring to Figure 23 C) then.Contiguous display device 11B analyzes the number of hops X that receives so that display device 11B determines that thereby it is will arrive analyzing similarly of display device 11B self to order (referring to Figure 23 D).Because it is the write command of light dead time information, display device 11B writes light inlet dead time information ((n-1) * Dn) to the light launch control unit 262 of display device 11B (referring to Figure 23 D).Number of hops X is updated and sends (referring to Figure 23 E) at one time.

Carry out such analysis of number of hops X and order, light dead time information write processing display device 11N (referring to Figure 23 F) to the last.Last then display device 11N writes light inlet dead time information, and number of hops X is updated and sends (referring to Figure 23 G).System control device 300B reception result also is back to system control device 300A (referring to Figure 23 H) with it.

This processing makes light dead time information be sent to all display device 11A to 11N.In this embodiment, when control frame arrived display device 11N, first display device 11A only waited for light emission n*Dn minute.This allows all display device 11A to launch (flashlamp illuminate) to 230N at synchronization light to the light emitting devices 230A of 11N.This guarantees the real-time response of light firing order and keeps tautochronism, thereby as one man carries out the flash of light control and treatment at synchronization.

The configuration of the control frame that Figure 24 A and 24B explanation are used when view data is launched.This configuration will be with the explanation of such situation, and wherein the view data (first page view data) of a frame that is made of the 640*480 pixel is launched successively by two line unit, as shown in figure 25.

The image data transmission order is at first used as an order, shown in Figure 24 A, in the head of image file, indicate every data of a page data (page), the total number of a line number (wire size) and two transmission lines (line number) is inserted in each corresponding head.

Except these Payload heads, the actual image data of two lines is set to the Payload main body.And the index of Payload head is used as the identification information of the view data that sends to any display device.For example, when view data was assigned to second display device 11B, the information of index=2 was set, shown in Figure 24 A.

The control frame that real-time processing section 330 generates and transmission is disposed like this of system control device 300A.Because do not match in the analysis of index information in first display device 11A, this display device 11A is only as delay element.The control frame information that receives at input port 242 is sent to output port 244.

When next display device 11B analyzes the Payload head, so that display device 11B determines that it will arrive display device 11B self, index information is mentioned and the index information coupling of the display device of itself and himself, thereby the view data that allows to be inserted into corresponding Payload main body is caught (referring to Figure 24 B) by image frame buffers 260.

When image frame buffers 260 stopped to catch view data, control frame was launched to output port 244 once more.Display device 11C below is in 11N, and its index information is different from the index information of their display device 11C to 11N, so they are only as delay element.Therefore, view data is assigned to object display device 11B.When all 480 lines had all transmitted, the certain hour section was kept in this batch operation.

When view data was dispensed to a display device 11i and stops, view data was dispensed to next display device 11i+1 and begins.In this case, the view data of " i " frame is assigned with, so the page=i is set.

As shown in figure 20, if the software of display device or firmware are transferred, this process can be discerned any display device, so that be shown in the such transfer processing among Figure 24 A and the 24B.

In instructions, illustrated that the view data of a frame is assigned to each display device 11A to 11N about Figure 24 A and 24B.Whether according to the travel speed of the electric car 4 that passes through, being assigned to each display device 11A has the view data of a frame or a frame to be present in contiguous display device to the view data of 11N.

In other words, according to the travel speed of the electric car 4 that passes through, the image of a frame can show with two adjacent display device.Therefore, be dispensed to each display device view data be to determine according to the travel speed of the electric car 4 that passes through.

Figure 26 illustrates such situation, and wherein the image of a frame is shown on the display device.For example, if the width (size) of the display unit 220 of display device 11 is 47 centimetres, the speed of electric car 4 is 50km/h when the image of a frame is shown on the display device, so that per second shows 30 width of cloth rest images.In order to explain, this speed is set to referring to speed.As shown in figure 26, if electric car 4 travels with reference velocity, the view data of a frame is assigned to each display unit 220A to 220N and show thereon.

Figure 27 illustrates such situation, if wherein electric car travels with regard to display image with half of reference velocity.If electric car 4 travels with half of reference velocity, the distribution of control view data so that the image of frame F1 is shown in display device 11A, and the image of frame F2 half be shown in display device 11A half be shown in contiguous display device 11B.

Figure 28 illustrates such situation, if wherein electric car 4 travels with regard to display image with the twice of reference velocity.If electric car 4 travels with the twice of reference velocity, the image of a frame is shown in every a display device ( display device 11A, 11C, etc.).Therefore, control the view data that to distribute based on the travel speed of electric car and allow to realize stable moving image naturally, even electric car travels with any speed.Certainly, light emitting devices 230 is based on the photoemissive interval while Be Controlled of the travel speed control of electric car.

Figure 29 explanation is used to carry out the process flow diagram of the indication treatment scheme (sketch map) of such operation.This processing can be applied to even each display device 11 does not have the situation of IP address.

As shown in figure 29, at step S71, display device 11 is initialised, and for example, storer is initialised.At step S72, search display device 11 and the MAC Address that is set by the user are dispensed to all mobile devices 11 automatically.The automatic distribution of MAC Address can be carried out on demand, but when display device has the through interface section of 3 ports, carries out the automatic distribution of MAC Address, and the through interface section of this 3 port will be explained below.

At step S73, view data is transmitted.At step S74, be collected the time delay of each display device 11 and the inherent delay time of display device of himself is stored in each display device 11.At step S75, finish light dead time of calculating each display device 11 when preserving its value in the collection of time delay.

Then, wait the approaching of electric car 4 to be detected.At step S76, if detect the approaching of electric car 4, the light frame emission is with certain interval generation and transmits that this time interval has the travel speed as control frame (velocity of approach) of real-time response based on it.If detect leaving of electric car 4, at step S77, the light frame emission generates at certain intervals and transmits, and this time interval has the rate of departure as control frame of real-time response based on it.Just, carry out light emission switching frame.Certainly, the travel speed of the electric car that passes through along display device 11 is fixed, and can use the light frame emission that is generated by the system control device 300A near end to carry out flashlamp.

Then, finish if detected leaving of electric car 4, the S78 that is transmitted in of light frame emission stops.Then, the approaching detection that it waits for electric car 4 does not once more finish and do not force at step S79.

Be necessary travel speed control image data transmission according to electric car.Therefore, in fact, at step S76 and S77, according to the travel speed of electric car, the travel speed of electric car is detected, and view data is transmitted, transmit image data not before the travel speed of electric car is detected.

Replacedly, with reference to Figure 30, below explanation had the embodiment of the image display of another kind of through interface section 440.In these embodiments, as top embodiment, components identical represents that with identical identification number and/or symbol its explanation will be omitted.

Have two ports though top through interface section 240 has been described, through interface section 440 has three ports, as shown in figure 30.To illustrate as an example with display device 11A below.

In this embodiment, provide the 3rd port C (I/O part) 446.The ethernet port of CPU board 480 is connected to the 3rd port 446.In order to give information, be positioned at the matching addresses test section 252A of port 242 and 244 and the output of 252B and be supplied to the 3rd port 446 by selector switch 482 to CPU board 480 or from CPU board 480 reception information.

Be used for the impact damper 484 of transmission timing adjustment in case catch from the information (control frame of CPU side) of CPU board 480 transmissions through port 446.Whether selector switch 486 is selected should to be transferred to first port 242 or second port 244 from the control frame of the CPU side of impact damper 484 outputs.If it is transferred to first port 242, the control frame of CPU side is provided to selects part 458B, at this CPU side control frame with to have passed through in the control frame of second port 244 any one selected and export first port 242 to.

Similarly, if be transferred to second port 244, the control frame of CPU side is provided to selects part 458A, at this CPU side control frame with to have passed through in the control frame of first port 242 any one selected and export second port 244 to.

The control frame of CPU side is the frame corresponding to ICP/IP protocol.

In order to realize such processing, the flow process control section 488 of header that the control frame (control frame that comprises the CPU side) that is used to monitor each transmission is provided is with control selector switch 482 and 486 and select part 458A and 458B.Flow process control section 488 is carried out various control and is handled as follows:

(1) if from the process of the 3rd port 446 transmission control frame to the second ports 244, receive general control frame (having the non real-time response) from first port 242, impact damper 484 is in case the control frame that storage receives from first port 242 and when when sending of the 3rd port 446 finished, and the control frame that is stored in impact damper 484 is transferred to second port 244 behind wait interframe gap (IFG).

(2) if from the 3rd port 446 transmission control frame to the second ports 244 processes, receive control frame from first port 242 with real-time response, frame buffer 260 is in case the control frame that storage receives from first port 242 and stop from the transmission of the 3rd port 446, wait for the IFG time period, thereby the storage control frame of read buffers 484 is to transmit it to second port 244.

This handles the assurance of eliminating tautochronism, if therefore having the control frame such as the light frame emission of real-time response is transmitted, when time of a frame maximum (maximum transmission unit) is maximum transmission unit (MTU), be necessary that time T (=(number of display device) * IFG+MTU) before transmission is from system control device 300A or the converse frame of 300B transfer bus.

(3) if from the process of first port, 242 transmission control frame to the second ports 244, receive the general control frame from the 3rd port 446, this processing that is similar to the regular tap hub is performed.

Because CPU board 480 has the IP address, when specific information was assigned to necessary display device 11, MAC Address was distributed automatically by the user, if or another network be connected to CPU board, itself and another network service.Use CPU board 480 to allow the information of non-top status information to be presented and to receive.Therefore, use through interface section 240 to allow its polyfunctional increase with three ports.

According to the image display 200 of this embodiment, communication path (communication cable) can reduce, and improves the frequency of setting operation thus.The image display 200 of this embodiment further has following good effect:

(1) because MAC Address can be distributed automatically, the pass between another MAC Address distribution permission MAC Address and any one display device ties up to when display device exchanges and eliminates, thereby improves the setting degree of freedom of display device.

(2) can transmit information and available low price communication cable (1000Base-T, 1000Base-TRX etc.) fast is used in the image display 200 of this embodiment.Compare with prior art, image display 200 has the message capacity that significantly improves.
