Multi-layer encoding and decoding

摘要: Innovations described herein provide a generic encoding and decoding framework that includes some features of simulcast scalable video coding. For example, bitstream multiplexer multiplexes component bitstreams into multi-layer (MLE) provides temporal scalability, spatial resolution scalability and/or signal to noise ratio scalability. Each the an alternative version input video, given can be non-scalable or bitstream. The follows composition rules for MLE may rewrite values certain syntax elements using approach avoids bit shifting operations. A corresponding demultiplexer receives demultiplexes at least part one from bitstream, following decomposition demultiplexing.
