Residual coding methods for video data compression
The granted patent US12047578B2 outlines a computer-implemented method for coding video sequences, focusing on the processing of prediction residual signals. The method involves receiving control information at the slice level, which includes a flag that influences the choice of coding method. Specifically, the method allows for two types of coding: transform residual coding and transform-skip residual coding. If the flag indicates a first value, the method determines that the coding method should be transform-skip residual coding. This approach aims to enhance the efficiency of video coding by adapting the coding method based on the provided control information.
Additionally, the patent describes a system designed for processing video signals that incorporates a memory for storing instructions and at least one processor to execute these instructions. The system performs the same functions as outlined in the method, receiving control information and determining the appropriate coding method based on the flag's value. Furthermore, the patent includes a non-transitory computer-readable medium that stores executable instructions for the described method, ensuring that the technology can be implemented across various computer systems. This innovation is significant for improving video compression techniques, potentially leading to better video quality and reduced file sizes.
