2. Description of the Related Art The calling telephone number notification service, which is a service for notifying a called party of a calling telephone number (calling ID), has been provided in the United States since 1987 under the service name of "Caller ID", and in September 1994. 4 already
It is being offered in 8 states, and the number of subscribers is as of the end of 1993.
It has reached 1.5 million, an increase of 50 percent over the previous year. Also in the United Kingdom, "Caller Display
Although the service has been started under the service name of “y”, in Japan, only similar services are currently provided between some ISDN terminals, and Yokohama, Nagoya for 6 months from the third quarter of 1996. , In the area of Fukuoka, the service is scheduled to start on a trial basis under the names of "calling phone number notification service" and "callback service."

Taking the example of Bell Atlantic Inc. in the United States, a service that displays the telephone number of the person who made the call on a display device attached to the called party's telephone is
It has been provided under the name of IQ service in Philadelphia etc. since 989. This is one of the flat-rate services called class service, and there are also the following class services.

(1) Rejection of incoming call of a specific number (Call B
lock) This service is already provided in Japan only in urban areas under the name of "Junk call refusal service" in Japan.

(2) Caller number search (Call Tra
This is so-called reverse detection, and when a specific number is called within a fixed time after a call, the other party's number, connection time, reverse detection time, etc. are recorded in the telephone company.

(3) Identification call (Priority)
Call) This is a service that allows you to change the ringing tone depending on the registered caller's telephone number. You can know whether it is a call from a relative, friend, etc. or a first time call before you make a call. it can.

(4) Automatic Redial (Repeat C
all) This is a service that connects when the other party is busy and the other party hangs up.

(5) Return of latest call (Return)
Call) This is a service that automatically dials the most recently received phone number, and you can make a call from a stranger here as well, and it is a particularly useful service when you search for a prank call.

There are many positive opinions on the above services from the viewpoints of privacy protection on the called side, prevention of mischievous calls, identification of callers such as police and fire departments, etc.
There are some negative opinions, such as the invasion of the privacy of the sender and the fact that the private telephone number is known.

In consideration of such negative opinions in both the United States and the United Kingdom, while applying the "normal notification" of the outgoing telephone number as a basis, by applying to the telephone company that the outgoing telephone number notification is not desired, It is also possible to set "normally non notification".

Even in Japan, even if "Normal notification" or "Normal non notification" is selected and the normal notification is selected, if the specific number is dialed before the destination telephone number, the calling telephone number will not be notified. It is considered to be.

[0012] American AT & T persons have the above (1)-
As a matter of course, the technology necessary for implementing the practical service as described in (5) has been patented for the following ideas.

Automatic number confirmation (ANI: Automatic Number)
Use Identification for security management of information (US500
3595). When you pick up the handset, you will hear who made the call (US4899358). The ringing tone changes depending on the callee or the ID of the caller (US4
995075). Change the answering machine response depending on the caller (US4996704). Display the incoming time and ID of voice mail on the screen (US5003577).

In addition to the above enumeration, many ideas for automating various processes on the exchange side by using the originating telephone number have been patented.

The inventor of the present invention aims to solve the problem from the standpoint of the user of the calling telephone number notification service, and first refers to "a display device connected to a telephone line having a calling telephone number notification function" (special feature Japanese Patent Application No. 7-292774).

The conventional calling telephone number notification service is realized by processing the calling telephone number on the network (telephone line network) and the exchange side. However, it goes without saying that the transmission of the outgoing telephone number itself, which is the core technology of the outgoing telephone number notification service, must be processed by the network and the exchange side. Regardless of whether the telephone number notification service is necessary or not, if it is attempted to process it on the network side and the exchange side, it will require a huge amount of money and time to prepare the infrastructure.

Furthermore, even if only those who wish to use the calling telephone number notification service are targeted, the usage method including the calling telephone number notification time differs depending on the user's usage pattern and lifestyle. Services are not able to satisfy users, but it is costly to configure a service system that can respond to each user's demands on the network side only, which leads to an increase in usage fees. So this is not a good idea either.

Various services such as display of the calling telephone number, rejection of nuisance call reception, reverse detection, and ringing tone for each caller can be processed by each receiving terminal as long as the calling telephone number is received. Therefore, it is considered desirable that each receiving terminal side processes the part related to the user interface in the calling telephone number notification service, and the reason why the above-mentioned "display device connected to a telephone line having a calling telephone number notification function" is proposed. It is here.

A switching device for notifying a calling telephone number and a terminal device (ID receiving terminal) having a receiving function for a calling telephone number such as the above-mentioned "display device connected to a telephone line having a calling telephone number notifying function". In between, the following communication is performed.

As shown in FIG. 20, first, the exchange side inverts the polarities of the lines L1 and L2, and then sends an ID reception terminal activation signal to the ID reception terminal. This ID
The ID receiving terminal that has received the receiving terminal activation signal returns a primary response signal.

Next, the exchange side transmits the calling telephone number to the ID receiving terminal. Upon receiving this calling telephone number, the ID receiving terminal displays the calling telephone number on the screen, displays information prepared in advance by associating with each calling telephone number, for example, displaying the caller's name, etc. or outputting voice. It can be done. Therefore, the ID receiving terminal can know in advance who the call is from before going off-hook. Further, depending on the content of the received calling telephone number, it is possible to determine in advance how to handle the incoming call, reject the incoming call, send a message, and the like.

The ID receiving terminal which has received the calling telephone number information returns a reception completion signal to the exchange side. When the exchange receives the reception completion signal, it sends a calling signal, and the ID receiving terminal makes a call by ringing a bell or the like. Here, when the ID receiving terminal side goes off-hook, a secondary response signal is sent to the exchange, and then the exchange side repolarizes the polarities of L1 and L2, so that communication is possible, that is, communication is in progress. . When communication is in progress, it is possible to send a message message or a rejection message. Also, after the message is sent, the line can be automatically turned off and the line can be disconnected.

[0023]

However, the terminal equipment having the function of receiving the outgoing telephone number as described above is
Connection to a switchboard and a telephone by adding a communication function such as an NCU and a modem to a general television receiver or the like configured to control the entire display operation by a built-in microcomputer (hereinafter referred to as a microcomputer) The above-mentioned microcomputer is provided with a calling telephone number notification receiving function by causing the above-mentioned microcomputer to execute the calling telephone number notification processing based on the calling telephone number received via the NCU and the modem.

Therefore, the television receiver having such a function of receiving the outgoing telephone number has an increase in cost and load power as compared with a normal television receiver due to an increase in memory capacity and an NCU and a built-in modem. It was a problem and was a problem.

On the other hand, looking at the future in which the calling telephone number notification service is widespread, it goes without saying that telephones with a calling telephone number receiving function are available at a widespread price, and control devices such as personal computers are widely used in ordinary households. However, it seems that television receivers are becoming more sophisticated and popular than they are today.

That is, the telephone has a calling telephone number receiving function, the computer has a control function consisting of a CPU, a memory, etc., and the television receiver displays characters, charts, etc. either on the broadcast image or independently. Situation in which there are resources distributed in the home that are more than sufficient to cover the functions equal to or higher than those of the television receiver having the above-mentioned calling telephone number receiving function, such as having a display function to There can be

Therefore, the present invention is not limited to one television receiver for calling telephone number notification, but telephones, television receivers in which people who want to use the calling telephone number notification service are dispersed in the home, There is a problem in providing a digital AV system that can be configured by linking and effectively using each resource possessed by a control device or the like.

[0028]

In order to solve the above problems, a digital AV system according to the present invention comprises a digital interface, AV equipment for processing audio and / or video signals, and the digital interface, / A control device including a recording unit and a control unit,
A digital AV system comprising: a communication device having the digital interface and having a communication function of appropriately connecting to a communication line to perform communication, wherein the AV device, the control device, and the communication device are mutually connected via a digital bus. Therefore, the control of the communication device is performed by the control device.

With the above configuration, it is possible to realize a digital AV system for performing processing such as reception of a calling telephone number without changing the capacity of the circuit or memory of each AV equipment constituting the system. .

[0030]

BEST MODE FOR CARRYING OUT THE INVENTION Before describing an embodiment of a digital AV system according to the present invention, an outline of a 1394 bus which is a typical digital bus will be described.

The 1394 bus is a serial bus that allows a plurality of AV devices to be removably connected in a daisy chain system or a tree system, and automatically notifies that a new node (AV device) is connected. Since it has the ability to detect, it has the advantage that even if a node is added or deleted, the work of resetting the ID of each node, resetting each device, etc. is unnecessary.

The cables constituting the 1394 bus are composed of two data lines, two strobe lines, and two power lines, for a total of six.
It is a bundle of lines of a book. Since there are two power lines, even if the power of a device in the middle of the bus is off, the power necessary for bus-throughing the signal can be supplied to the power-off device. It is possible to normally access the device beyond the device that has been dropped.

On the other hand, data transfer is performed by serial transfer using a total of four data lines and two strobe lines. There are two sets of data lines and strobe lines, and there are two sets of these two lines. The reason why there are two data lines and two strobe lines is that in the 1394 bus, the voltage level is determined not by the voltage level of the reference potential, but by which of the two signal lines is higher. By doing so, it is possible to prevent malfunction due to fluctuations in the ground level.

Also, two lines of signal lines, a data line and a strobe line, are used, but this is not to place a clock on the strobe line to synchronize with the data line, but only when the same data continues on the data line. This is because the voltage level of the strobe line is changed and the strobe line is not changed when the data changes on the data line. That is, the data of the data line is read when the potential of either the data line or the strobe line changes. This method is called a DS-link method. This DS-
According to the link method, the two signal lines are resistant to fluctuations with time, and it is possible to prevent malfunction due to a timing difference between the data line and the strobe line. Further, since it is not necessary to insert a start bit and a stop bit as in the conventional serial transfer, the transfer speed is improved.

At both ends of the cable thus constructed,
It has a connector with a built-in transceiver. By connecting this connector to the 1394 interface section of the AV device, connection in a daisy chain system or a tree system becomes possible.

The 1394 bus has a bus arbitration function in order to prevent a specific device from monopolizing the bus and a plurality of devices from using the bus at the same time. In the 1394 bus, data is transferred as a packet, and the size of this packet is determined to be 512 bytes at the maximum. In addition, unlike other interfaces, since no priority order is set among the devices, all the devices have an equal relationship. Therefore, as a general rule, it is not possible to transfer a huge amount of data at once, and if there is another device that wants to transfer data, the transfer right must be transferred to that device, and wait until the transfer ends. A situation may arise in which it must be.

However, in the 1394 bus, an "emergency packet" is prepared for the case of really urgent data transfer, and the transfer right has not been given for the time being because the transfer has already been completed. However, the packet can be sent with priority over other devices up to three times.

The most characteristic function of the 1394 bus is the "isochronous transfer" function which allocates a fixed width of the bus to the transfer of multimedia data and the like. In order to realize this function, the 1394 bus has a packet called an "isochronous packet" in addition to a normal packet and the above-mentioned emergency packet. This isochronous packet is
It is intended for the transfer of data that requires real-time processing.For example, when connecting a digital camera and a sampling microphone, even if there are many emergency packets from other devices, the video and audio will be interrupted. Is provided because it is in trouble.

This isochronous packet is transferred with priority over any packet including an urgent packet. The 1394 bus transmits a start packet every 1/8000 second, and when the start packet is output, the transfer right is given to the isochronous packet, and other packets cannot be transmitted until the transfer is completed.

Therefore, it is also possible to input in Chinese characters, and Fig. 6B shows an example of the registration screen 62 after the input is completed.

In addition to the preset table 60 and the user registration table 61, an incoming call history table and fixed data such as still images and animations are stored in the EEPROM or the like and can be read out as needed. FIG. 7 shows a display example 63 of the incoming call history table. This is to display the dial status at the time of incoming call, such as rejection, absence, incoming call, etc., and its time in a table.

The incoming call history table is also used for call back (auto return dial). That is, by displaying the incoming call history table on the screen of the control device PC, operating the mouse to select the other party as shown in FIG. 7 and pressing the confirmation button, the telephone PH can be called back. In this case, an on-hook dial command is transmitted from the control device PC to the telephone PH in advance, and an actual call is made only by the telephone PH.

FIG. 8 shows a telephone icon as an example of fixed data. FIG. 8A shows a telephone in an on-hook state, and FIG. 8B shows a telephone in an off-hook state. While the call signal is being received, the icon shown in FIG. 8A blinks or vibrates due to animation. It is also possible to move the position or change the shape as needed.

Hereinafter, the operation for notifying the originating telephone number of the digital AV system including the television receiver TV, the telephone PH, and the control device PC will be described with reference to FIGS.
This will be described with reference to the flowchart shown in FIG. In these flow charts, "calling telephone number" is described as "calling ID".

When making a call, the exchange first inverts the polarity of the subscriber line 58 and sends a calling ID activation signal. Upon receiving the polarity reversal of the subscriber line 58 and the originating ID activation signal, the telephone set PH forms a direct current loop on the subscriber line 58 to transmit the primary response signal to the exchange.

When the exchange side receives the primary response signal,
The caller ID notification or non-notification reason is sent. The non-notification reason category indicates whether the caller refuses to send the caller ID, the call is from outside the service area, or the call is from a public telephone.

Upon receiving the calling ID from the exchange, the telephone PH, which is a communication device, notifies the control device PC of the calling ID information through the 1394 I / F 53. That is, control device PC
Can be said to be monitoring the state of the communication line. Therefore,
It is also possible to record and manage the response history and the like at the time of incoming and outgoing calls in the disk device or the like of the control device PC. Upon receiving the calling ID information via the 1394 I / F 34, the control device PC that has received this notification starts executing the calling telephone number notification process shown in FIG. 9 (steps ST1 and ST2).

When the calling ID information received here by the control device PC is "non-notification", the reason for non-notification is checked, and the following processing is performed according to the reason (step ST3).

(1) When the non-notification reason is an incoming call from outside the area, the character string "outside area (blue)" of the display data is set in a specific area (display buffer) of the RAM for storing the display data. Along with the audio data "out of area", a specific area (audio buffer) of the RAM that stores the audio data
(Steps ST4, ST5, ST6).

(2) If the reason for non-notification is rejection of transmission of the outgoing telephone number, the character string "notification of notification" in the display data
(Red) is set in the display buffer, and the voice data in the case of notification rejection is set in the voice buffer (step S
T7, ST8, ST9).

(3) When the non-notification reason is a call from a public telephone, the display data "public telephone" (green) is set in the display buffer, and the voice data "public telephone" is set in the voice buffer ( Steps ST10, ST11, S
T12).

(4) When the reason for non notification is unknown, the display data "?" Is set in the display buffer, and the voice data when unknown is set in the voice buffer (step S).
T10, ST13, ST14).

After the display data is set in the display buffer as described above, the control device PC stores the display data in 1394.
Transfer to the television receiver TV via the I / F and request display.

On the other hand, when the calling telephone number is notified,
As shown in FIG. 10, the user registration table 61 is searched for registration data corresponding to the notified calling telephone number (steps ST3 and ST16).

When the same telephone number as the notified calling telephone number is registered in the calling telephone number 61a of the user registration table 61, the incoming call setting information which is the processing information at the time of incoming call corresponding to the calling telephone number. Check 61d (steps ST17 and ST24).

On the other hand, when the same telephone number as the notified telephone number is not registered, the preset table 60 is searched next (steps ST17, ST1).
8).

Calling telephone number 6 in preset table 60
If there is a telephone number corresponding to 0a, the display information is extracted from the preset table 60 and transmitted to the television receiver TV, and the digital audio data is set in the audio buffer (steps ST19, ST22, ST).
23). On the other hand, if there is no corresponding data in the preset table 60, the display data is created only with the calling telephone number, and the default voice data is created and set in the voice buffer (steps ST19, ST20, ST2).
1).

If there is no designation of automatic incoming call in the incoming call setting information 61d of the user registration table 61, the registration table 6
The character string 61b of 1, for example, "Shinjuksara" is extracted and transmitted to the television receiver TV, and the selected melody, for example, "melody 2" is extracted and set in the voice buffer (steps ST25 and ST26). When there is an automatic incoming call designation, the control device PC sends 1 to the telephone PH.
After instructing the telephone PH to go off-hook via the 394 bus and connecting the telephone PH to the exchange, one voice message registered in the user registration table 61 is displayed.
It is transmitted to the other party through the 394 I / F and the telephone PH (steps ST27, ST28). In this case, when the automatic incoming designation is a message, the message is repeatedly transmitted until the other party hangs up (steps ST28, ST2).
9, ST30).

If the NCU 40 has a call signal determining means for determining whether it is an extension line or an outside line, when the telephone PH is called, information indicating whether it is an extension line or an outside line is sent to the CPU 44.
To the CP of the control device PC.
If it is transferred to U, it is possible to change the display contents and the voice of the voice output depending on whether it is an extension line or an outside line.

Next, after instructing the telephone set PH to go on-hook via the 1394 bus to disconnect the line with the exchange, the outgoing telephone number and the automatic incoming call history are recorded in an EEPROM or the like together with time data. End (step ST3
1, ST32). The contents recorded here can be viewed at any time on the screen as shown in FIG.

Next, the voice data set in the voice buffer of the control device PC, that is, the dial tone, the melody, or the area name is repeatedly transmitted to the telephone PH through the 1394 bus (step ST33). This enables the telephone PH
From, the dial tone, melody, or area name is repeatedly output. The area name voice data is output in a format such as "Call from Sapporo".

Next, the control device PC receives 1 from the telephone PH.
If there is an off-hook detection notification through the 394 bus, the voice output is stopped and the outgoing telephone number and incoming call history are EEPR.
It is stored in the OM or the like and waits until the on-hook detection signal is transmitted from the telephone PH (steps ST34, ST3).
5, ST36).

When the calling signal is lost without the notification of off-hook detection from the telephone PH, that is, when the other party hangs up, the output of the voice data from the voice buffer is stopped, and the calling telephone number and the non-incoming call are received. History and EEPR
The display is stored in the OM or the like, and the television receiver TV is instructed to end the display through the 1394 bus and the display is ended (steps ST34, ST37, ST38, ST39,
ST45).

When the telephone PH has an off-hook and is busy, either the telephone PH goes on-hook, the other party hangs up, or a certain period of time elapses.
The call end time is recorded in the EEPROM or the like, and the television receiver TV is instructed to end the display through the 1394 bus to end the call (steps ST41 and ST4).
2, ST43, ST44, ST45).

The message transmitted to the television receiver TV as described above is displayed on the TV screen 7a as shown in FIGS. 12 to 15, for example. FIG. 12 shows a case where the reason for non notification of the outgoing telephone number is a public telephone, FIG. 13 shows a case where the reason for non notification of the outgoing telephone number is unknown, and FIG. 14 shows a case where the outgoing telephone number is notified and is not registered in the user registration table 61. FIG. 15 shows respective display examples when there is a call from “Shinjuksara” registered in the user registration table. In these displays, it is possible to display each information in different colors.

In the embodiment described above, the telephone PH
Has been described as being connected to an analog telephone line, but as shown in FIG.
If you have U, connect it to a digital telephone line,
Based on the calling telephone number notified from the digital telephone line, the same operation as that of the digital AV system described above can be performed.

In the embodiment shown in FIGS. 1 and 16, the television receiver TV, the telephone PH, and the control device P are used.
Cs exist independently and are connected to each other via the 1394 bus. However, if the resources owned by each device can be effectively utilized, these devices do not necessarily have to be independent. For example, as shown in FIG. 17, a function corresponding to the telephone PH, that is, an MO, is provided in the television receiver TV.
If equipped with DEM and NCU
MODE in television receiver TV via 94 bus
By controlling M and NCU, the same operation as that of the digital AV system described above can be realized.

In this case, the television receiver TV
Since the communication function is provided inside the TV receiver TV, the cost is increased as compared with the normal TV receiver TV, but the communication function is controlled by the separate and independent control device PC. The functions and performances relating to the reception of the outgoing telephone number can be improved by improving only the control device, for example, expanding the functions by improving the software and increasing the processing capacity by increasing the memory capacity.
Therefore, digital AV can be performed without a significant increase in cost.
It is possible to improve the function and performance of the entire system.

Further, as shown in FIG. 18, the control device PC can be provided with the functions of MODEM and NCU. In this case, MO in the card slot of the control device PC
In addition to the method of inserting a card having the functions of DEM and NCU, the above-mentioned digital method can also be obtained by a method of connecting a communication device having the functions of MODEM and NCU to the outside through a serial interface equipped in the control device PC. It is possible to realize an AV system. still,
Even in this case, the cost of the AV device such as the television receiver TV does not increase, and the performance of the entire system can be improved by improving the function and performance of the control device PC as described above.

Further, the control device is not limited to a personal computer as long as it has a CPU, a memory / recording means such as a memory, and a 1394 interface. For example, in the case of a family computer as shown in FIG. Good.

Also, in FIGS. 17 and 18, the MOD
Although it is connected to an analog line via EM and NCU, when connecting to a digital line such as ISDN,
The following connections are possible. (1) AV equipment or control equipment-MODEM-NCU-T
A-DSU-Digital line (2) AV device or control device-TA-DSU-Digital line (3) AV device or control device-DSU-Digital line

The function of the base unit or the handset of the cordless telephone can be incorporated in the control device PC in the form of a board. In this case, when the user off-hooks the telephone side that is actually used for the call, the name of the calling area can be heard only from the handset before the call is started by communication by the command between the base unit and the handset.

[0110]

As described above, the digital AV system according to the present invention has a calling telephone number receiving function,
In addition, since the caller-related information can be displayed and / or voice output, "a display device connected to a telephone line having a calling telephone number notification function" (Japanese Patent Application No. 7-2927).
74), the following effects are exhibited.

(1) When the caller-related information is displayed on the screen of the television receiver, the information regarding the call and the caller being received while watching the screen of the television receiver which is the display device. Is displayed on the TV screen in large size, so no special calling telephone number receiving terminal is required. (2) Even if the caller cannot be specified, the caller area is displayed, which makes it easier to assume the caller and also the call charge to be paid by the other party.

(3) Even if the calling telephone number is not notified,
If you know the reason for non-notification such as public telephone, outside the area, and refusal of notification, it is easy to assume the originator. For example, it can be assumed to some extent that a call is sent from a public phone during the return time to notify the user of returning home, or if a call is sent from outside the area, it is a call from a rural person. In addition, when the notification is rejected, the call can be avoided.

(4) Even when the user is not looking at the device displaying the sender related information, it is possible to assume the sender and the calling area by the difference in the ringing tone. (5) By registering the correspondence between the telephone number and the caller in advance, a large number of callers can be recorded within the allowable range of the memory, and can be identified immediately upon receiving a call. Of course, you can't forget it unless the device breaks down. This is because humans have a limit in remembering the correspondence between a telephone number and a caller, and according to a survey by the Ministry of Posts and Telecommunications, the telephone number that they remember is 6 to 10 persons per person including services such as 107. It is an individual. Also, even if you remember it, you may not be able to remember it immediately.

(6) Since the caller is known before going off-hook, the voice and attitude at the beginning of the conversation can be changed according to the other party, so that the call can be smoothly carried out. (7) Not only is it displayed, but the color is changed for each display element, so it is easy to recognize.

(8) It is possible to block unwanted calls. In this case, since the blocking service of the telephone company is not used, the monthly service charge is unnecessary. Blocking messages are not only preset but can be recorded with your own voice, so not only for prank calls but also for blocking reasons (eg "I loved someone. Don't call me anymore." ) Is also available.

(9) When leaving, the message can be transmitted to a specific sender. (10) For the latest missed call, the calling telephone number and the caller can be specified on the display screen and called back.

(11) Since the calling telephone number and the attribute of the specified caller are recorded in the incoming call history, it is possible to know the importance of the content by checking the history by checking the history. In addition, you can check the number of times you have had a nuisance call, the time, and whether or not a message has been transmitted.

Further, the digital AV system according to the present invention includes the above-mentioned "display device connected to a telephone line having a calling telephone number notification function" (Japanese Patent Application No. 7-29277).
In addition to the effect of 4), the following effect is also achieved. (1) Since the resources of each AV device are effectively used, it is not necessary for each AV device to newly have a circuit or memory for calling telephone number notification processing, thus increasing the cost of each AV device. It is possible to build a system that can receive the outgoing telephone number notification service without being allowed to do so. (2) It is possible to cope with the expansion of the calling telephone number notification service only by improving the software operating on the control device such as a personal computer. (3) The functions and performance of the entire digital AV system can be improved by improving the functions of the control device such as a personal computer, for example, by increasing the capacity of the memory and the disk and improving the speed of the CPU.
