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.
