1. A method of encoding video for transmission through a computer network comprising the steps of:

  • (a) receiving at an encoder a video input, comprising a plurality of frames of a video containing initial video data and encoding said initial video data as encoded video data, such that said encoded video data is comprised of fewer bytes than said initial video data;

    (b) transmitting said encoded video data through said computer network to a decoder that receives said encoded video data and reconstructs a plurality of images representative of said video input for viewing on a display;

    (c) sensing with a sensor display information identifying physical presentation characteristics of said display and viewer information representative of at least one of a location and movement of a viewer; and

    (d) transmitting viewer data representative of said viewer information and said display information to said encoder so as to modify the method of said encoding of said initial video data wherein said method of encoding is modified in response to both said viewer information and said display information.
