Abstract
Official abstract text for this publication.
In a method and apparatus for encoding an input video bitstream to produce an encoded output bitstream, a base stream is enhanced based on enhancement control parameters. At least one picture content parameter is extracted from the enhanced base stream. At least one picture content parameter is extracted from the input video bitstream. The enhanced picture content parameters are compared with the input picture content parameters. An output from the comparison step is received and the enhancement control parameters are calculated so as to minimize the difference between the input picture content parameters and the enhanced picture content parameters. The calculated control parameters are incorporated into the encoded output bitstream.
First claim
Opening claim text (preview).
The invention claimed is: 1. A decoder for decoding a base layer stream with incorporated enhancement control parameters, said decoder comprising: a decoder decoding the base layer signal to create a base layer image; and separating the enhancement control parameters from the base layer stream; and an enhancement unit enhancing the base layer image based on said enhancement control parameters. 2. A decoder for decoding compressed video information, sai…
