摘要： A multimedia communication apparatus so adapted that when the transmission speed of video information on a communication line is inadequate, transmission of the video information is suspended and notification is given of the fact that suspension of transmission is in effect. When communication is on hold, only prescribed media information is transmitted and needless connections are cancelled. In response to a designation releasing the apparatus from the holding state, the connection state which prevailed prior to hold is promptly restored and communication is resumed.

摘要： When a no-communication state is detected for a predetermined time of time during communication in response to an interrupt designation to or from an apparatus on the other end of the line, an operation of a time monitoring timer for terminating the communication is interrupted. The time monitoring timer is restarted in response to a restart designation. Therefore, communication can be continued without interrupting an interrupt/restart service provided by, e.g., an ISDN due to a time-out error. When a trouble which disables communication occurs during communication, an interrupt service is requested to a network. When the trouble which disables communication is recovered, a restart service can be requested to the network. In this case, communication can be normally restarted without being accidentally terminated intermediately.
