Abstract

In a conventional multipoint videoconferencing system, one can take part in the conference only from an H.320-compliant dedicated communication terminal. According to the present invention, a general-purpose terminal is connected to a multipoint videoconferencing system via the Internet and video from a communication terminal is converted to HTML data, which is then distributed to the general-purpose terminal. Voice communication between the communication terminal and general-purpose terminal is made possible by making a suitable conversion between the voice communication protocols of the two terminals. As a result, even a transportable general-purpose terminal, for example, can participate in videoconferencing.
