Abstract: The techniques of this disclosure relate to video encoding and include using an inter mode determination for neighboring blocks, rather than the final prediction mode determination for the neighboring block, when determining an inter mode for a current block. In this way, inter mode and intra mode estimation may be separated and performed in different stages of a multi-threaded parallel video encoding implementation. In addition, this disclosure also proposes generating sub-pixel values in a third stage of the multi-threaded parallel video encoding implementation at a frame level, rather than for each macroblock during inter mode estimation process for that macroblock.

Abstract translation: 本公开的技术涉及视频编码，并且包括当确定当前块的帧间模式时，使用相邻块的帧间模式确定而不是相邻块的最终预测模式确定。 以这种方式，可以在多线程并行视频编码实现的不同阶段中分离和执行帧间模式和帧内模式估计。 此外，本公开还提出了在帧级别的多线程并行视频编码实现的第三级中生成子像素值，而不是在针对该宏块的帧间模式估计处理期间为每个宏块生成子像素值。
