Abstract

A Video Server (100) encodes a video stream according to the values of parameters and transmits the video stream over a Network (200) to a Video Client (300) that decodes the received video stream for presentation to a user. As the video stream is being received, the Video Client (300) continually gathers data regarding at least the condition of Network (200) sends this data to Video Server (100). The Video Server (100) modifies the values of the parameters based on the data received from Video Client (300), which in turn modifies the encoding of the video stream.
