Abstract:
1. A system comprising: a bit rate control system including a source model scaled by an interest structure to generate a quantization value for use in encoding a macroblock, the interest structure including an interest matrix having a plurality of entries, wherein each of the plurality of entries comprises a non-zero number corresponding to a macroblock, and none of the plurality of entries takes on a zero value, wherein the non-zero number comprises a number greater than zero; the bit rate control system including a sequence of macroblocks input operable to receive a sequence of macroblocks including the macroblock, and an output coupled to a video encoder operable to provide an encoded video output; and a region of interest identification system communicatively coupled to the bit rate control system, the region of interest identification system including a user input operable to receive one or more user inputs that identify a region of interest in a real time video communication generated from the encoded video output, the regional of interest identification system including an input to receive the transmitted encoded video, and an output coupled to the bit rate control system, wherein the output is operable to provide a region of interest information to the bit rate control system based on the one or more user inputs, wherein the bit rate control system is operable to determine a value for at least one of the plurality of entries based on the region of interest information.
