AI Technical Summary
Existing video coding standards face inefficiencies in achieving high compression ratios while maintaining subjective quality, particularly with the development of advanced standards like VVC/H.266, which require optimized signaling of sub-block transform information to enhance coding efficiency.
Implementing a method and apparatus for encoding and decoding that selectively enable or disable sub-block transform (SBT) based on specific syntax elements, reducing unnecessary signaling overhead by only enabling SBT when necessary, and determining maximum coding unit sizes dynamically.
Enhances video coding efficiency by optimizing signaling and resource utilization, thereby achieving better compression performance without increasing bandwidth, aligning with the goals of the VVC/H.266 standard.
