Abstract: A TV conference terminal which is used by a plurality users prevents an error connection at the conference held, makes the operation simple, and holds the conference smoothly. The TV conference terminal provides an operating panel wherein a user registers a password of each user, and the names and the abbreviated telephone number of partners and communication parameters. A backup RAM stores the above mentioned registered information and a controller controls this information. After the user registers the password, the name and the abbreviated telephone number of the partner are registered. After the registration of the above mentioned information, at the time when the TV conference terminal connects to the TV conference terminal of the partner, communication parameters decided by the communication procedure of ITU-T recommendation H.242 are registered in the backup RAM.

Abstract: When a teleconference among more than two places is performed using a multi-point teleconference system, each of teleconference terminal units makes a connection to a multi-point control unit by line. When the number of participants in the teleconference reduces during the teleconference so that the teleconference is performed between only two places, a conference state managing section requests the two teleconference terminal units to make a point-to-point-connection. When the point-to-point connection is acknowledge by these teleconference terminal units, the teleconference by the multi-point control unit is finished. Thereafter, the line is automatically connected between the two teleconference terminal units to perform a teleconference in the style of the point-to-point connection, so that a fee paid for use of the line is one-half compared with that in the case of the prior art.
