Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a multimedia information communication terminal capable of exchanging multimedia information with another terminal via a communication network and a plurality of multimedia information communication terminals. The present invention relates to a multimedia information communication system, and more particularly, to a multimedia information communication terminal device and a multimedia information communication system capable of smoothly exchanging input / output capabilities performed in each terminal device.

[0002]

2. Description of the Related Art Some multimedia terminals have various capabilities. For example, a document image processing terminal having a printer / FAX / document storage capability can convert the data format internally in addition to printing out the document data transmitted from the personal computer, and further perform FAX transmission to another terminal. It is possible. Also, the document data stored in the internal storage device can be transmitted to the personal computer upon request from the personal computer.

As an example of a conventional multimedia information communication terminal, there is Japanese Patent Publication No. 7-101899 entitled "Comprehensive Service Digital Network Communication Terminal". This terminal device sets the communication mode of its own terminal in the user / user information element of the transmission message and sets the communication mode of the own terminal when the call control unit performs the call disconnection / release procedure. A communication mode recognizing unit for recognizing the communication mode of the partner terminal from the user / user information element of the received message received from the partner terminal and comparing the communication mode with the communication mode of the own terminal stored in the mode storage unit; A communication mode changing unit for changing the communication mode based on the result; and a recalling control unit for executing a recalling procedure based on the changed communication mode and the subscriber number of the partner terminal stored in the number storage unit. ing.

[0004]

In general, when performing communication, it is desirable to be able to exchange / recognize the capabilities of the partner terminal at the earliest possible stage of information transmission and reception. However, Japanese Patent Publication No. Hei 7-101899 discloses a method of exchanging the communication mode of a partner terminal at the time of call setup. What data format the partner terminal changes and outputs information transmitted to the partner terminal is described. This is not considered at all. That is, Japanese Patent Publication No. 7-101899
The apparatus disclosed in the above publication cannot recognize whether the partner terminal has the capability of only printing out, or whether it can be converted to a FAX format and FAX output to another terminal. Similarly, it is not possible to exchange or recognize the capability of inputting information, for example, whether a moving image is an input from a storage device or an input from a video camera.

[0005] The transmission and reception of information is asymmetric in printout and transmission of stored data. That is, printout is mainly transmitted from the own terminal to the partner terminal, whereas transmission of stored data is mainly received. This greatly depends on the information input / output and conversion capabilities of both terminals. Therefore, when exchanging capabilities between terminals, it is more appropriate to handle information transmission and reception separately, but the device disclosed in Japanese Patent Publication No. 7-101899 does not consider this point at all.

[0006] Further, if the capability of inputting / outputting and converting information is exchanged separately for actual transmission / reception of information, the amount of information for exchanging the capability increases. In the above-mentioned multi-functional terminal, the amount of information for exchanging the capability is particularly increased. However, in the device disclosed in Japanese Patent Publication No. 7-101899, no consideration is given to an increase in the amount of exchanged information at the time of call setup.
