ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a television conference registration method and a terminal thereof which can be used by a plurality of users. Hereinafter the television conference is referred to as the TV conference.
Description of the Related Art
At conventional TV conference terminals, the terminals are mutually connected to plural terminals disposed at different places utilizing an ISDN (integrated services digital network). When a conference is held, the method to directly dial a telephone number of a partner or to dial an abbreviated telephone number of the partner registered beforehand is used as a dialing means for calling from a host TV conference terminal to a TV conference terminal of participants of the partner.
In the conventional way, the abbreviated telephone numbers of all users are generally registered at one terminal of the TV conference. The registered abbreviated telephone number has the information about the telephone number and the name of the TV conference terminal. At the time when the host TV conference terminal connects to the desired TV conference terminal, the host terminal displays a table having the registered information, selects a desired abbreviated telephone number and calls that number.
However, the conventional TV conference terminal has the following problems. A first problem is that at the case of the terminal which is used by plural users and calls using the abbreviated telephone number, the terminal needs time to search for the desired abbreviated telephone number from the many registered telephone numbers.
This is because at the conventional terminal, regardless of the number of users, the abbreviated telephone numbers are registered in unity in the total TV conference system and each terminal does not have a registration means for registering the abbreviated telephone number individually.
A second problem is that at the case which a user has used before and changed a voice mode and a data speed and so forth, a next user may not recognize this change and hold a TV conference. As a result, for example, a voice mode of G. 711 is applied and an image rate may be decreased. This is undesirable for the subsequent user.
The reason this problem occurs is that, regardless of connecting partners, the conventional terminal of the TV conference uses the communication parameters such as the voice mode and the data speed set beforehand and does not have a storing means for storing the communication mode while the communication regulated by the communication procedure ITU-T recommendation H.242 is preformed.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a TV conference registration method and a terminal thereof in which a user inputs each password of a user and registers an abbreviated telephone number and a name of a partner. The user further, registers communication parameters such as a voice mode, a communication speed, a data speed and so forth. With these entries the user can hold a conference with a setting registered by the user and can search for the partner within the registered abbreviated telephone numbers, can prevent an error connection and can hold a conference smoothly without complexity.
According to a first aspect of the present invention, to achieve this object, the TV conference registration method using a TV conference terminal used by plural users holding conferences in common provides the steps of giving a password for a user, inputting the password by the user, inputting an abbreviated telephone number of a TV conference terminal of a partner to whom said user inputted said password wants to connect, registering said inputted password and said abbreviated telephone number of the TV conference terminal of the partner attached to said password, and connecting to a telephone line of said registered partner using said abbreviated telephone number.
According to a second aspect of the present invention, it is desirable that the TV conference registration method has a registering step to register the setting of communication parameters including a voice mode, a communication speed and a data speed attached to said password, at the connection to the telephone line of the TV conference terminal of the partner from the TV conference terminal used by the plural users in common.
According to a third aspect of the present invention, the TV conference terminal which is used by plural users in common provides a password giving means for giving a password for a user upon request of a registration of the user, a first registration means for storing the password inputted by the user, a second registration means for storing an abbreviated telephone number of the TV conference terminal of a partner attached to said password inputted by said user, and a connecting means for connecting to a telephone line of the TV conference terminal of the partner using the stored abbreviated telephone number by controlling the operation of the TV conference terminal of the user.
According to a fourth aspect of the present invention, the TV conference terminal at the communication with said TV conference terminal of the partner, implements the communication procedure of ITU-T recommendation H.242 responding to the communication parameters including a voice mode, a communication speed and a data speed registered attaching to the password. In this case, the TV conference terminal registers the communication parameters decided by said communication procedure of ITU-T recommendation H.242 attached to said abbreviated telephone number. With this, at the time when said TV conference terminal connects to the TV conference terminal of the partner again, said TV conference terminal implements the communication procedure of ITU-T recommendation H.242 using the communication parameters including the voice mode, communication speed and data speed registered attaching to the abbreviated telephone number. This operation is desirable.
