Figure 4 illustrates further application of the invention.In this was used, the combination of RF transmitter 30 and IR reflector 31 was to portable set 33 broadcast datas.Portable set has RF and IR receiver.The RF data flow comprises the captioned test of encryption, digitized audio frequency and the control data that is used for a theater 34 or a plurality of places.Each theater or place have one or more IR reflectors, and it sends low volume data, thereby the reproduction of portable set is synchronized to user's the position or the statement of theater.The reflector that is installed in the theater inlet can send the identification code that is used for portable set identification theater.Then, equipment extracts the data at this theater content from RF stream, and with load content in the memory of equipment.Content can comprise theater name, projection time, projection summary, and the text of the projection that is about to begin and audio frequency.When the user entered theater, equipment received the IR synchronous code at current projection, and device displays caption text, perhaps audio plays, and perhaps other synchronizer is worked during showing.As described above, from show media, obtain the IR synchronous code.
Fig. 5 has described the example embodiment of the basic structure of the data packet flows that is sent by high speed transmitter.
With the projection program of theater for example and current date supplementary with the time, the possible broadcast packet stream of theater presentation content at three theaters shown in this figure.
Broadcast packet stream comprises small set of data (grouping), and it comprises by the small amounts of content that subscriber equipment received, and if desired, will be loaded in the subscriber equipment local storage.The logic state of each subscriber equipment has determined which grouping is loaded in the concrete subscriber equipment.For example, the subscriber equipment in theater A will receive and store the content at theater A, but ignore the content at theater B and C.All subscriber equipmenies will receive current time grouping, and service time the data subscriber equipment clock of resetting.Any user equipment before theater A, B and C will receive and store the schedule data of theater.Exemplary packet among the figure shows the content that is separated into 1/2nd fragments.Therefore, the captions equipment among the theater A will receive first second captioned test grouping at projection, at second second captioned test grouping etc.Content will be loaded into and be used for during showing visit in the device memory each second.
It can be a large amount of single packet types, each comprises different data, for example captioned test, audio content, video content, figure, image, time, program, menu, geography information, game content, study a question, advertisement, warning, alarm etc.
Each packet (with reference to the captioned test among the figure 5, audio content, current time grouping) always begins to represent unique head (header) value that new packet begins.
Packet also comprises the count value that is used for representing to divide into groups to attach data volume.Counting be used to confirm grouping and calculation check and.
Enciphered data is represented key and confirmation.This together with verification and, make in the user equipment authentication grouping data subsequently be used for equipment, and confirm that data do not have destroyed.Key and confirmation are loaded in the subscriber equipment accordingly.
Content-data in the grouping of type of message value defined.Based on type of message, how subscriber equipment will determine the decoded packet data, where store data, how and when use data.For example, can show alert text immediately; The projection captioned test can be buffered in the device memory, trigger the demonstration of captioned test up to the IR synchronous code.Menu or program information can be buffered in the device memory, need it up to the user.
Address value has been specified the identifier that is used for receiving equipment.This can be unique address, and therefore grouping only is used for a subscriber equipment.Perhaps, a plurality of subscriber equipmenies can be stipulated in the address, for example, and all captions equipment or all game stations.Perhaps, the address can be shown grouping sheet the common broadcast that sends to all devices.
Option zero-time value is as grouping serial number, but also can use by receiving subscriber equipment, thereby when definition use packet content.When receiving grouping, subscriber equipment buffers into its memory with content according to the order based on zero-time.When subscriber equipment receives synchronous code, it will obtain content from sequential memory or searching storage, be used to have the content of suitable zero-time.For example have caption text data, digitized audio content and the current time of format code and the additional information of frame information, be included in the data packet flows.
Have verification and information, it uses the combination of all aforementioned data to check grouping to arrive its position fully.
Fig. 6 has described the example embodiment according to portable user of the present invention.All portable sets have common means: IR receiver 50, RF receiver 60, IR transmitter 51, RF transmitter 61, processor 52, memory 54 and power supply 56.The planned application of other parts of equipment and changing.In this example embodiment, except the audio frequency amplifier 57 that is used to play sound, described sound can be the form of speech or musical sound, and portable set has the display 53 that is used for videotex and/or figure.Memory 54 is places of storage data on equipment.The code that IR receiver 50 receives from transmitting set, and processor 52 code analysis.Processor 52 interpretive codes, thus how determine to its processing.If code is used for this equipment, equipment is searched in its memory 54 and the corresponding content of code.Displaying contents on display 53 then, and/or play sound by audio frequency amplifier 57.Portable set shown in Figure 5 for example shows also that the user of button imports 55, and it can be used for interactive application.Can be used for when portable set accurately aims at the location synchronous code at the IR receiver system, high speed RF receiver system can be used for to portable set transmission content.
Fig. 7 shows the flow chart how packet that received is handled by subscriber equipment.After the equipment energising, can receive packet from IR and RF receiver.Equipment is also monitored can be from user's input of button, touch-screen, phonetic entry, auxiliary equipment etc.Equipment also reads clock periodically, and is its temporal database memory of event searching in the prestrain that is set at that time to trigger.
Arbitrary receiver can be discerned the input grouping.The input grouping that to ignore any data that comprise timing error, damage, can't confirm etc.Have the correction bit that can authorize and decipher regularly, proofread and correct header and have correction verification and grouping, be marked as effectively.
To effectively divide into groups and user device configuration compares, thereby only can use suitable grouping.For example, can only dispose the subscriber equipment that shows captioned test but do not have audio capability at text.This equipment will be ignored the grouping that comprises audio content.
Packet message type determines how equipment will use grouped data.Grouping can comprise the content that is buffered in the subscriber equipment content database memory, uses after being used for, for example captioned test, audio frequency or video.Can immediately for example other data of urgent text alert message be sent to device display.For example the data of position and time synchronized sign indicating number can cause that equipment searches for its content database memory, extracts content and rendering content.Current time data makes its internal clocking of device reset.The event time data are positioned in the content database memory of equipment, and work during the time when the internal clocking match event.The special-effect data can cause subscriber equipment drone ring, ring rings, active etc.
Subscriber equipment can have available user and import number.These can adopt the forms such as auxiliary equipment of button, touch-screen soft, touch-screen menus, phonetic entry, for example breath-taking puff switch.The user can be provided with preference, for example point of interest, film types, age, level of education etc.Equipment can use the preference of these manual inputs with known preference, thereby changes the statement of content.For example, children's equipment can be configured such that the demonstration captions with less English glossary.Because children carry equipment to diverse location in the museum, equipment also can " be known ", perhaps infers the preference of children for specific display type.
Equipment can also be known user's direct of travel, and therefore predicts or prompting destination in the future.For example, after the corridor that goes north down, equipment can warn the user corridor to reach an end soon, and needs eastwards or change in the west.In addition, known to direction with known to any and the preference manual input of user, can cause that equipment infers for the preference in the face of the displaying in the east of the corridor end.
According to for based on the current location of subscriber equipment, in the path history of the time that certain position consumed, the position of visiting (promptly, geographical traveling history) and the time that is consumed between the position (promptly, the use of the equipment speed of travel), portable set can be inferred user's preference automatically.
User's input can also be distributed to device hardware functions.For example, load button can cause that the IR transmitter sends code to nearby device.This code can be discerned each user, is automation equipment, network etc. with User Recognition perhaps.For example, one section code can cause and open the door, and perhaps allows with games system mutual etc.
Subscriber equipment can be represented the content based on internal logic and internal clocking thereof, and does not receive packet.For example, text subtitle can occur the scheduled time by day, thereby projection time, the shut-in time of reminding customer site are perhaps reminded the required medicine of user etc.In addition, by the User Preferences of known and manual input, can logically retrain this time-event.For example, can not show restaurant's shut-in time, because the user has walked out the restaurant.
At last, should be appreciated that embodiments of the invention disclosed herein are descriptions of principle of the present invention.Can adopt other modification within the scope of the present invention.Therefore, the present invention be not limited in this explanation the content that clearly illustrates and describe.
