Abstract
A peripheral video conferencing system is housed in a peripheral housing and adapted for communication with an analog or digital communication channel and a separate host computer system. Audio, video, and data file information is transmitted to and received from a remote conferencing site over the communication channel. A plurality of audio, video, and communication channel connectors provide means for acquiring source audio and video signals, and respectively displaying on a separate monitor and broadcasting over an internal or separate external speaker remote video images and audio. A high-speed output interface provides connectivity with the separate host computer system for coordinating, in cooperation with video conferencing application software operating thereon, the presentation of local and remote NTSC or video images on a display coupled to the computer system.
