RESIDUAL CODING TO SUPPORT BOTH LOSSY AND LOSSLESS CODING

Abstract:

An example device includes memory configured to store video data and one or more processors implemented in circuitry and coupled to the memory. The one or more processors are configured to determine whether transform skip mode is used for a current block of the video data. The one or more processors are configured to disable level mapping for residual coding based on transform skip mode being used for the current block. The one or more processors are configured to code the current block without applying level mapping.
