AI Technical Summary

Technical Problem

Existing video encoding/decoding methods suffer from redundancy when both merge motion vector difference (MMVD) and triangle prediction unit (triangle PU) modes are used under the same conditions, leading to increased coding resources and bit overhead.

Method used

A method and apparatus that selectively parse and encode indicators for MMVD and triangle PU modes based on their usage, allowing inter prediction to be performed using MMVD or triangle PU modes independently, thereby reducing redundancy and bit overhead by ensuring only necessary indicators are encoded or decoded.

Benefits of technology

This approach reduces coding resources and bit overhead by avoiding redundant encoding/decoding of MMVD and triangle PU modes, enhancing the efficiency of video encoding/decoding processes.

Abstract

A video picture decoding and encoding method and a video picture decoding and encoding apparatus are provided.SOLUTION: When it is determined that the merge mode or the skip mode is used, if it is determined through decoding that a merge mode with motion vector difference (MMVD) indicator is true, a trianglepredictionunit (trianglePU) indicator may not be coded. The trianglePU indicator is coded only when it is determined through decoding that the MMVD indicator is false. This can reduce a quantity of used coding resources and reduce bit overheads of a bitstream.SELECTED DRAWING: Figure 10A
