AI Technical Summary
Existing technologies suffer from low encoding efficiency, increased memory access bandwidth, and complex hardware logic in high-resolution and high-quality image encoding/decoding. In particular, in motion compensation using traditional merging modes, the parallelism and dependency of merging candidate derivation processing limit encoding/decoding efficiency.
A combined candidate merging mode is adopted, including one-way prediction, two-way prediction, three-way prediction and four-way prediction. By parallelizing the candidate merging derivation process, the dependency between candidate merging derivation processes is removed, and the motion vector related reference frames in the same frame are used as reference frames for temporal merging candidates.
It improves video encoding/decoding efficiency, simplifies hardware logic, enhances throughput in merge mode, and reduces memory access bandwidth.
