摘要: Methods and systems for parallel rate-constrained motion estimation in a video encoder are provided. Embodiments of the present invention provide solution problem reliance upon spatial dependencies when processing RCME on frame. In order to solve this problem, embodiments determine list at least two Motion Vector Predictor Candidates (MVPC), determine, said MVPCs, corresponding (MVC) using Rate-Constrained Estimation (RCME) optimal (MV) among determined MVCs based rate distortion optimization.
