Abstract
A video microcode resides on a video board of the computer conferencing system. A video capture driver, a video manager, and a video applications programming interface reside on a general-purpose host processor of the computer conferencing system. The video microcode receives local analog video signals, generates local compressed video signals corresponding to the local analog video signals, and passes the local compressed video signals to the video capture driver. The video capture driver controls the operations of the video microcode and passes the local compressed video signals to the video manager. The video manager passes the local compressed video signals to a communications subsystem of the computer conferencing system for transmission over a communications link to a remote computer conferencing system. The video manager receives remote compressed video signals from the communications subsystem and passes the compressed video signals to the video capture driver, the communications subsystem having received the remote compressed video signals over the communications link from the remote computer conferencing system. The video capture driver generates remote decompressed video signals corresponding to the remote compressed video signal for local playback.
