Peripheral audio/video communication system that interfaces with a host computer and determines format of coded audio/video signals
First Claim
1. A system for communicating with a communication channel and a separate host processor, the separate host processor being housed within a computer system housing and being coupled to a display, the system comprising:
- a peripheral housing separate from the computer system housing; and
an audio/visual communication system integral to the peripheral housing, the audio/visual communication system comprising;
a source input interface that receives a source audio signal and a source video signal;
a local transmission interface that selectably transmits a coded source audio signal and a coded source video signal to either one of an analog or a digital communication channel;
a local receive interface that receives a coded remote audio signal and a coded remote video signal transmitted over the either one of the analog or the digital communication channel and automatically determines the format of the coded remote audio and video signals; and
an output interface, comprising an output connector, that communicates the remote video signal between the local receive interface and the output connector;
wherein the output interface receives at the output connector a coordination instruction produced by the separate host processor and communicates the coordination instruction between the output connector and the local receive interface, and the separate host processor, when coupled to the output connector, receives the remote video signal in response to the coordination instruction for displaying a corresponding video image on the display.

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 PAL video images on a display coupled to the computer system.
