    • The present invention relates to a method for a video encoder to determine an inter mode. The video encoder selects first search modes by using optimized inter mode information of a correlation macroblock having the same position as a current macroblock in a previous frame, in order to determine the inter mode. The video encoder compares a rate-distortion cost of the correlation macroblock and a rate-distortion cost of the mode that is selected as the minimum cost mode from among the first search modes, and determines whether to terminate an inter mode determination process early. When the early termination condition is satisfied, the video encoder determines the search mode having the minimum rate-distortion cost from among the first search modes as the optimized inter mode of the current macroblock, and terminates the inter mode determination process early. When the early termination condition is not satisfied, the video encoder selects second search modes to additionally perform an inter prediction process, and determines the corresponding search mode having the minimum rate-distortion cost as the optimized inter mode of the current macroblock.
    • 本发明涉及一种视频编码器确定帧间模式的方法。 视频编码器通过使用具有与前一帧中的当前宏块相同位置的相关宏块的优化的帧间模式信息来选择第一搜索模式,以便确定帧间模式。 视频编码器将相关宏块的速率失真成本与从第一搜索模式中选择为最小成本模式的模式的速率失真成本进行比较,并且确定是否提前终止帧间模式确定处理。 当满足提前终止条件时,视频编码器将第一搜索模式中具有最小速率失真成本的搜索模式确定为当前宏块的优化帧间模式,并且提前终止帧间模式确定处理。 当不满足提前终止条件时,视频编码器选择第二搜索模式以附加地执行帧间预测处理,并且将具有最小速率失真成本的相应搜索模式确定为当前宏块的优化帧间模式。
