Abstract
A video subsystem resides partially on a host processor and partially on a video board. Audio and communications subsystems reside partially on the host processor and partially on a audio/communications board. The video subsystem generates and passes local compressed video signals corresponding to local analog video signals to the communications subsystem. The audio subsystem receives and generates local compressed audio signals corresponding to local analog audio signals to the communications subsystem. The communications subsystem transmits the local compressed video and audio signals over a communications link to a remote computer system. The communications subsystem also receives remote compressed video and audio signals over the communications link from the remote computer system, and passes the remote compressed video and audio signals to the video and audio subsystems, respectively. The video subsystem generates remote analog video signals corresponding to the remote compressed video signals for local playback. The audio subsystem generates remote analog audio signals corresponding to the remote compressed audio signals for local playback.Applicants
