Abstract
A decoder includes circuitry configured to receive a bitstream identify, in the bitstream, a current frame, wherein the current frame includes a first region and a third region, detect, in the bitstream, an indication that the first region is encoded according to a lossless encoding protocol, and decode the current frame, wherein decoding the current frame further comprises decoding the first region using a lossless decoding protocol corresponding to the lossless encoding protocol.
Claims20
A decoder, the decoder comprising circuitry configured to:
- receive a coded video bitstream;
- identify, in the bitstream, a current frame, wherein the current frame includes a first region, a second region, and a third region;
- detect, in the bitstream, that the first region is encoded using block differential pulse code modulation;
- detect, in the bitstream, that the second region is encoded using transform skip residual coding;
- and
- detect, in the bitstream, that the third region is encoded using lossy encoding, wherein the lossy encoding includes at least one of inter-prediction and intra-prediction.
A method of combined lossless and lossy coding, the method comprising:
- receiving, by a decoder, a coded video bitstream;
- identifying, by the decoder and in the bitstream, a current frame, wherein the current frame includes a first region, a second region, and a third region;
- detecting, by the decoder and in the bitstream, that the first region is encoded using block differential pulse code modulation;
- detecting, by the decoder and in the bitstream, that the second region is encoded using transform skip residual coding;
- and
- detecting, by the decoder and in the bitstream, that the third region is encoded using lossy encoding, wherein the lossy encoding includes at least one of inter-prediction and intra-prediction.
The method of claim 16, wherein the sub-picture header is explicitly included in data corresponding to the current frame.
