1. A videoconferencing appliance connected externally from a personal computer for decompressing non-video signals, said personal computer including a network interface for receiving compressed remote audio and video streams from a remote conference endpoint and a processor for distributing compressed remote audio stream to the videoconferencing appliance via a first communication interface for decompression so that the first communication interface directs the remote audio stream away from said personal computer, the video conferencing appliance comprising:

  • a microphone for generating a local audio stream;

    a video camera for generating a local video stream;

    an audio encoder, coupled to the microphone, for compressing the local audio stream;

    a video encoder, coupled to the video camera, for compressing the local video stream;

    a second communication interface, coupled to the audio and video encoders and the first communication interface, for conveying the compressed local audio and video streams to said personal computer and for receiving the remote audio stream from said personal computer; and

    an audio decoder for decompressing the compressed remote audio stream received from said personal computer through the second communication interface.
