Computer workstation.

摘要

A computer workstation runs an application 10 to participate in a video conference. The workstation contains a video adapter card 18 which converts a video signal produced by a camera 20 into a hardware specific format. Likewise, the video adapter card can also be used to display incoming video signals that are in the same hardware specific format. The workstation also contains software support modules (SSM). On the capture side, the SSM 16 provides a video signal in bit map form for transmission to terminals in the conference which do not have compatible video hardware. Correspondingly, on the display side the SSM 34 receives and displays incoming video signals in bit map form from other workstations which likewise do not have compatible hardware.
