Method and apparatus for spatial scalability for video coding
Abstract:
In a video distribution system, a divider to segment an input video stream into partitions for each of a plurality of channels of the video stream is provided. A channel analyzer is coupled to the divider wherein the channel analyzer decomposes the partitions. An encoder is coupled to the channel analyzer to encode the decomposed partitions into an encoded bitstream wherein the encoder receives coding information from at least one of the plurality of channels to be used in encoding the decomposed partitions into the encoded bitstream. A decoder receives the coded bitstream to decode the received bitstream and to reconstruct the input video stream. The decoder uses the coding information to decode the bitstream.
