Abstract:
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes, from a coded video bitstream, a flag that is indicative of whether applying a lossless coding mode. In response the flag being indicative of applying the lossless coding mode, the processing circuitry partitions a block into multiple blocks based on the block having at least one side that is equal to or greater than a threshold size for zeroing out a portion of the block. Thus, video quality loss due to zero out can be avoided. Then, the processing circuitry reconstructs the multiple blocks respectively from the coded video bitstream based on the lossless coding mode.
