Abstract
Disclosed is a method comprising: (a) receiving a layer 0 bitstream, the layer 0 bitstream including coding information for the layer 0 bitstream; (b) receiving a layer 1 bitstream, the layer 1 bitstream including coding information for the layer 1 bitstream; and (c) reconstructing the layer 0 bitstream using previously received information for another layer 0 bitstream and previously received information for another layer 1 bitstream.
Claims22
A method comprising:
- dividing a video stream into at least one low frequency sub-band partition and at least one high frequency sub-band partition;
- decomposing the video stream into a layer 0 bitstream and a layer 1 bitstream, the layer 0 bitstream decomposed based on the at least one low frequency sub-band partition, the layer 1 bitstream decomposed based on the at least one high frequency sub-band partition;
- encoding the layer 0 bitstream and the layer 1 bitstream, the layer 0 bitstream encoded using at least one of coding information for the layer 0 bitstream or coding information for the layer 1 bitstream, the layer 1 bitstream encoded using the coding information for the layer 1 bitstream;
- and
- reconstructing the video stream, the reconstructing including decoding the encoded layer 0 bitstream and the encoded layer 1 bitstream and recombining the decoded layer 0 bitstream and layer 1 bitstream into a reconstructed video stream using at least one of the coding information for the layer 0 bitstream or the coding information for the layer 1 bitstream.

An apparatus comprising:
- a processor;
- a divider including instructions executable by the processor to divide a video stream into at least one low frequency sub-band partition and at least one high frequency sub-band partition;
- a channel analyzer including instructions executable by the processor to decompose the video stream into a layer 0 bitstream and a layer 1 bitstream, the layer 0 bitstream decomposed based on the at least one low frequency sub-band partition, the layer 1 bitstream decomposed based on the at least one high frequency sub-band partition;
- and
- an encoder including instructions executable by the processor to encode the layer 0 bitstream and the layer 1 bitstream, the layer 0 bitstream encoded using at least one of coding information for the layer 0 bitstream or coding information for the layer 1 bitstream, the layer 1 bitstream encoded using the coding information for the layer 1 bitstream.
