Abstract

(57) [Summary] [Purpose] To provide a videophone / videoconference communication terminal device capable of performing efficient telephone / conference by reducing the size of registration data. [Structure] When the registrant data is not registered, the registration means 1 reduces the data amount of the image data received together with the detected call number and registers it in the registration storage means 2 instead of the registrant data. Since the image data to be registered is automatically reduced in data amount and stored, the registrant data can be registered only by operating the terminal without requiring a large capacity memory.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videophone / videoconference communication terminal device.

[0002]

2. Description of the Related Art Currently, ISDN (International Servic
e Digital Network: Comprehensive service digital communication network)
Line interfaces have been standardized and are being put to practical use. From such a trend, videophone / videoconference communication terminal devices for transmitting audio / video, etc. via the ISDN line have begun to spread.

In this videophone / videoconference communication terminal device, a B channel (64 Kbps) / H0 channel (384 Kb) by a basic interface or a primary group interface is used.
ps) -Communication using the H1 channel (1536 Kbps) is performed.

In order to communicate with the partner terminal device in this communication terminal device, it is necessary to exchange information such as the contents and changes of the terminal capability between the ISDN line (the partner communication terminal device) and the communication terminal device. There is.

When performing this communication, first, as shown in FIG. 4, an outband signal (D channel) is used to make a call. In this way, communication on the B channel becomes possible depending on the call setting and the response from the terminal device. The other party inserts the call number into the call setting data for transmission, while the terminal device receiving the call setting data determines the other party's call number from the call setting data.

The method of inserting the call number into the communication data is, as shown in FIG. 4, that there is a message of call setting from the line to the terminal as a request for setting the access connection, and then from the terminal to the line. Communication is possible with a message called response that notifies the reception of access connection acceptance. As the communication path, the D channel for performing call setting / response, the B channel including communication contents,
In addition, there are the H0 channel and the H1 channel, but only the D channel is used here.

Here, the D channel will be briefly supplemented. The D-channel call control signal is used for B-channel link setup for realizing circuit switching and packet switching on the B-channel. Also, in this D channel packet exchange, the JT-X25 packet level protocol is used. The information elements in the D channel call setting / response include a call for notifying the calling side that the called side is calling, a call setting reception for notifying the completion of reception of all call setting information, and a calling side for the called side call reception. Notify the response, confirm the response to notify the caller to the called user, display the progress of the status notification such as interconnection with non-ISDN, call setting request call setting, call setting completion notification There is a call setup confirmation. Some of these systems judge and display the other party based on the judged call number.

However, although many of these systems describe the transmission method, they do not describe much about the registration method of the call number, especially the registration method of the call number of the videophone / videoconference communication terminal device.

[0009]

When the above-mentioned videophone / videoconference communication terminal device performs reception, if the determined caller number of the other party is not registered in the registration storage means, the caller number of the other party is displayed. You have to write it down once and then type it into the terminal. At that time, there is a possibility that the description of the call number may be incorrect, and it is troublesome to make a note. Furthermore,
In the case of a system for registering a registrant name, a company name or the like has a drawback that the registration function is not effective because the name alone does not give an impression in some cases and it takes time to remember.

On the other hand, the amount of data in the registrant data including images and the like at present is enormous, and there is a problem that the present system requires a large amount of memory.

Therefore, the present invention has been made in view of the above circumstances, and provides a videophone / videoconference communication terminal device capable of efficiently performing a telephone / conference by miniaturizing registration data. The purpose is to provide.
