Abstract
A video encoding method and apparatus for adapting a video input to a bandwidth of a transmission channel of a network that includes determining the number N enhancement layer bitstreams capable of being adapted to the bandwidth of the transmission channel of a network. A base layer bitstream is encoded from the video input wherein a plurality of enhancement layer bitstreams are encoded from the video input. The enhancement layer bit-streams are based on the base layer bitstream, wherein the plurality of enhancement layer bitstreams complements the base layer bitstream and the base layer bitstream and N enhancement layer bitstreams to are transmitted to the network.
Claims11
A video encoding method for selectively adapting a video input for transmission over a specific channel of a network, wherein said network includes a plurality of channels, said channels having a plurality of different bandwidths, the method comprising the steps of:
- determining number N of enhancement layer bitstreams capable of being adapted to said particular bandwidth of said specific transmission channel of said network;
- encoding a base layer bitstream from said video input;
- encoding N number of enhancement layer bitstreams from said video input based on the base layer bitstream, wherein the N enhancement layer bitstreams complement the base layer bitstream;
- and
- providing the base layer bitstream and N enhancement layer bitstreams to said network.
