Peripheral video conferencing system
First Claim
1. A stand-alone video-conferencing system comprising:
- a housing;
a first receive unit that receives a local audio signal and a local video signal;
a local transmission unit that transmits the local audio signal and the local video signal to a communication channel;
a second receive unit that receives a remote audio signal and a remote video signal transmitted over the communication channel;
an output interface, comprising an output connector, that communicates the remote video signal between the second receive unit and the output connector; and
a control unit that controls the presentation of the remote video signal through the output connector and adjusts the transmission bandwidth of the communication channel;
wherein the first receive unit, local transmission unit, second receive unit, and output interface are disposed in the housing.

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.
