Constrained block-level optimization and signaling for video coding tools

摘要

An example device for decoding encoded video data includes storage media and processing circuitry. The storage media are configured a portion of the encoded video data. The processing circuitry is configured to determine a block-level threshold for the portion of the encoded video data stored to the storage media, to determine that an encoded block of the portion of the encoded video data has a size that is equal to or greater than the threshold, to receive a syntax element indicating that a portion of the encoded block is to be reconstructed using a coding tool, to determine, based on the encoded block having the size that is equal to or greater than the threshold, that the syntax element applies to all samples of a plurality of samples included in the encoded block, and to reconstruct the encoded block based on the coding tool.
