Claim 2:
3. An encoder for encoding a bitstream, the bitstream adapted to be decoded by a decoder being configured to:
receive the bitstream, the bitstream including a coded picture, the coded picture including a first coded sub-picture and a second coded sub-picture, the bitstream also including a first sub-picture header and a second sub-picture header;
detect in the first sub-picture header that the first sub-picture is coded using a lossless encoding protocol;
detect in the second sub-picture header that the second sub-picture is coded using a lossy encoding protocol,
decode the first sub-picture using a protocol for lossless decoding corresponding to the detected lossless encoding protocol; and
decode the second sub-picture using a protocol corresponding to the detected lossy encoding protocol.
