摘要： In a video conference between N parties, each video conferencing terminal produces a respective video signal comprising, in the case of the National Television Standard Committee (NTSC) standard, sixty fields per second. The input video signals are input to an analog multi-point control unit which selects every Nth field from each input video signal and derives therefrom a single output video signal also of sixty fields per second, in which consecutive fields are derived cyclically from each of the N input video signals in turn. The single output video signal is transmitted to each video conferencing terminal, which separates out the fields of the input video signals present in the single output video signal to provide N individual reduced field rate video signals each comprising 60/N fields per second and each having fields derived from a respective one of the input video signals.

摘要： The present invention relates a communication terminal for the synchronization of audio and visual information within a communication system. Audio communication between the parties to a video conference is achieved by digitizing the speech and transmitting the same over a packet based data network. Each party to the conference can draw the attention of the other party to an object on the screen using a pointer controlled by, say, a mouse or ball. The co-ordinates of each parties' pointer are incorporated, via a multiplexer, into the data packets containing the digitized speech and transmitted to the other party's terminal thereby ensuring the synchronization the pointer information with the digitized speech.
