Abstract
An encoder includes circuitry configured to receive an input video, select a current frame identify a first sub-picture of the current frame to be encoded using a lossless encoding protocol, and encode the current frame, wherein encoding the current frame includes encoding the first sub-picture using the lossless encoding protocol. An encoded bitstream provided by an encoder is also provided.
