AI Technical Summary

Technical Problem

Existing video coding standards like HEVC and VVC face challenges in achieving optimal compression efficiency and bitrate reduction while maintaining video quality, particularly in handling residual and coefficient coding.

Method used

The method involves determining the presence or absence of specific flags in the syntax structure for residual coding and using alternative Rice parameter derivations for binarization, along with separate coding methods for transform coefficients and skip coefficients, and employing dependent scalar quantization to enhance compression efficiency.

Benefits of technology

This approach improves video coding efficiency by optimizing residual and coefficient coding, leading to better compression performance and reduced bitrates without compromising video quality.

Abstract

To provide a method, an apparatus, and a non-transitory computer readable storage media for a video coding are provided.SOLUTION: A method for a video coding includes: a step of receiving, by a decoder, a sequence parameter set (SPS) residual encoding flag that indicates whether index sh_ts_residual_coding_rice_idx is present in a SH syntax structure that refers to the SPS; a step of determining sh_ts_residual_coding_rice_idx is present in a slice head (SH) syntax structure that refers to the SPS in response to determining that a value of the SPS residual encoding flag is equal to 1; and a step of determining that the sh_ts_residual_coding_rice_idx is not present in the SH syntax structure that refers to the SPS in response to determining that the value of the residual encoding flag is equal to 0.SELECTED DRAWING: Figure 19
