ABSTRACT:
A communications task resides on an audio/communications board of the computer conferencing system. A communications manager and a communications application programming interface reside on a general-purpose host-processor of the computer conferencing system. The communications manager receives local compressed video signals from a video subsystem of the computer conferencing system and passes the local compressed video signals to the communications task. The communications task receives local compressed audio signals from an audio task of the computer conferencing system, the audio task residing on the audio/communications board. The communications task transmits the local compressed video signals and the local compressed audio signals over a communications link to a remote computer conferencing system. The communications task receives remote compressed video signals and remote compressed audio signals over the communications link from the remote computer conferencing system. The communications task passes the remote compressed audio signals directly to the audio task for decompression and playback processing. The communications task passes the remote compressed video signals to the video subsystem for decompression and playback processing.
