Lossless coding of video data
Systems and methods for performing residual coding of video data include receiving control information for coding a video sequence and determining, based on the control information, a coding method for coding a prediction residual signal of a coding block in the video sequence. The coding method is one of a transform residual coding and a transform-skip residual coding.
1. A computer-implemented method, comprising:
receiving control information for coding a video sequence, wherein the control information is signaled at a slice level for a slice of the video sequence and includes a flag; and
determining, based on the control information, a coding method for coding a prediction residual signal of a coding block in the video sequence, the coding method being one of a transform residual coding and a transform-skip residual coding, wherein in response to a value of the flag being a first value, determining the coding method to be the transform-skip residual coding.
2. The method according to claim 1 wherein the coding block is associated with the slice.
3. A system for processing video signals with residual coding, comprising:
a memory for storing a set of instructions; and
at least one processor configured to execute the set of instructions for causing the system to perform:
receiving control information for coding a video sequence, wherein the control information is signaled at a slice level for a slice of the video sequence and includes a flag; and
determining, based on the control information, a coding method for coding a prediction residual signal of a coding block in the video sequence, the coding method being one of a transform residual coding and a transform-skip residual coding, wherein in response to a value of the flag being a first value, determining the coding method to be the transform-skip residual coding.
4. A non-transitory computer readable medium storing instructions that are executable by at least one processor of a computer system, wherein the execution of the instructions causes the computer system to perform a method comprising;
receiving control information for coding a video sequence, wherein the control information is signaled at a slice level for a slice of the video sequence and includes a flag; and
determining, based on the control information, a coding method for coding a prediction residual signal of a coding block in the video sequence, the coding method being one of a transform residual coding and a transform-skip residual coding, wherein in response to a value of the flag being a first value, determining the coding method to be the transform-skip residual coding.
