Abstract
Official abstract text for this publication.
A method of decoding an enhanced video stream composed of base layer video access units and enhancement layer video access units, each access unit comprising a plurality of syntax structures, includes passing the syntax structures of the base layer access units to a base layer buffer, passing syntax structures of the enhancement layer access units to an enhancement layer buffer, outputting the syntax structures passed to the base layer buffer in a predetermined sequence, outputting the syntax structures passed to the enhancement layer buffer in a predetermined sequence, and recombining the sequences of syntax structures output by the base layer buffer and the enhancement layer buffer respectively to form a complete enhanced access unit, composed of base layer syntax structures and enhancement layer syntax structures in a predetermined sequence.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of creating an enhanced video signal comprising: receiving a unitary bitstream conveying, in a plurality of packetized elementary streams, base layer access units and enhancement layer access units, wherein each enhancement layer access unit comprises video layer syntax structures and non-video layer syntax structures, separating a base layer program stream and an enhancement layer program stream from the unitary bitstream, and including n…
