Abstract

In a point-to-multipoint system, the first communication processing apparatus generates a signal to inquire of the second communication processing apparatus about languages used in the second terminals and transmits the signal to the second communication processing apparatus. The second communication processing apparatus generates a second signal which includes data indicating the language which is used most in the second terminals and transmits the second signal to the first communication processing apparatus.

Claims

1. A broadcast communication system in which a prescribed information is transmitted from a first terminal to a plurality of second terminals via a first communication processing apparatus and a second communication processing apparatus, and said first terminal is connected to said first communication processing apparatus, and said plurality of second terminals are connected to said second communication processing apparatus, said broadcast communication system comprising:

a plurality of information outputting apparatuses that are provided in said first terminal and that output information to be communicated from said first terminal to said plurality of second terminals, and each said information that is output from said information outputting apparatuses having a same content and having different languages from each other;

a first means, provided in said first communication processing apparatus, for generating a first signal to inquire of said second communication processing apparatus about the languages used in each of said plurality of second terminals and transmitting said first signal to said second communication processing apparatus, when said first communication processing apparatus receives from said first terminal a request to communicate between said first terminal and said plurality of second terminals;

a second means, provided in said second communication processing apparatus, for generating a second signal which includes data indicating a one of the languages which is used most in said plurality of second terminals and transmitting said second signal to said first communication processing apparatus, when said second communication processing apparatus receives said first signal from said first communication processing apparatus; and

a third means, provided in said first communication processing apparatus, for establishing a connection between said first communication processing apparatus and said second communication processing apparatus so as to communicate between said plurality of second terminals and respective ones of said plurality of information outputting apparatuses of said first terminal using the one of the languages specified by said second signal, when said first communication processing apparatus receives said second signal from said second communication processing apparatus.

2. The broadcast communication system according to claim 1, further comprising a fourth means, provided in said first communication processing apparatus, for establishing a plurality of connections between said first communication processing apparatus and said plurality of information outputting apparatuses of said first terminal, when said first communication processing apparatus receives from said first terminal a request to communicate between said first terminal and said plurality of second terminals.

3. The broadcast communication system according to claim 1, wherein said data indicating the language most used in said plurality of second terminals is automatically selected from data provided in said second communication processing apparatus.

4. The broadcast communication system according to claim 1, wherein said data indicating the language most used in said plurality of second terminals is specified by said second communication processing apparatus.

5. The broadcast communication system according to claim 3, wherein the language selected by said second communication processing apparatus is based on a count of a number of times each language is used in said plurality of second terminals.

6. A communication method using a broadcast communication system in which a prescribed information is transmitted from a first terminal to a plurality of second terminals via a first communication processing apparatus and a second communication processing apparatus, and said first terminal is connected to said first communication processing apparatus, and said plurality of second terminals are connected to said second communication processing apparatus, and said first terminal having a plurality of information outputting apparatuses which output information to be communicated from said first terminal to said plurality of second terminals and each said information that is output from said plurality of information outputting apparatuses having a same content and having different languages from each other, said method comprising the steps of:

transmitting from said first terminal to said first communication processing apparatus a request signal to communicate between said first terminal and said plurality of second terminals;

generating a first signal to inquire of said second communication processing apparatus about the languages used in each of said plurality of second terminals and transmitting said first signal to said second communication processing apparatus, when said first communication processing apparatus receives said request signal from said first terminal;

establishing a plurality of connections between said first communication processing apparatus and said plurality of information output apparatuses of said first terminal, when said first communication processing apparatus receives said request signal from said first terminal;

generating a second signal which includes data indicating a one of the languages which is used most in said plurality of second terminals and transmitting said second signal to said first communication processing apparatus, when said second communication processing apparatus receives said first signal from said first communication processing apparatus; and

establishing a connection between said first communication processing apparatus and said second communication processing apparatus so as to communicate between said plurality of second terminals and said plurality of information outputting apparatuses of said first terminal using the one of the languages specified by said second signal, when said first communication processing apparatus receives said second signal from said second communication processing apparatus.
