Patent ID: 7474796

Claim:
Apparatus for generating a media stream and transmitting the media stream to a terminal, comprising: an originating server having a binary scene encoder, a rasterizer, a processor, a memory, and server software, the server software configured to transmit said media stream to said terminal; wherein the binary scene encoder comprises a computer program configured for generating a scene graph, traversing the scene graph to determine an order of nodes, traversing the scene graph in the reverse of said order, and determining a heuristically optimal placement of quantization parameter nodes while traversing the scene graph in the reverse of said order; wherein the rasterizer comprises a processor and a computer program configured for generating a bit map and a set of pixels responsive to information generated by the computer program; wherein the terminal is configured to receive different media streams from the rasterizer, integrate the media streams at the terminal, and comprise a single presentation for a viewer.
