Abstract
An encoder receives a video input that includes initial video data and encodes the initial video data as encoded video data, such that the encoded video data comprises fewer bytes than the initial video data. The encoded video data is transmitted through a computer network to a decoder that receives the encoded video data and reconstructs an image representative of the video input for viewing on a display. A sensor senses at least one of viewer information representative of at least one of a location and movement of a viewer, and display information identifying the display. Viewer data representative of the at least one of the viewer information and the display information is transmitted to the encoder to modify the method of encoding the initial video data.
