Abstract
公开了一种通过使用基于子块的运动补偿处理视频信号的方法和设备。具体地，视频信号处理方法可以包括以下步骤：获取指示是否基于子块的合并模式被应用于当前块的第一语法元素；以及当第一语法元素指示基于子块的合并模式不被应用于当前块时，获取第二语法元素，该第二语法元素指示是否使用运动矢量差的合并模式被应用于当前块；当第二语法元素指示使用运动矢量差的合并模式被应用于当前块时，获取第三语法元素，该第三语法元素指示用于当前块的合并候选列表中包含的候选当中被用在当前块的帧间预测中的候选；获取与运动矢量差有关的信息；通过将运动矢量差与由第三语法元素指示的候选的运动矢量相加来导出当前块的运动矢量；以及通过使用当前块的运动矢量来生成当前块的预测块。
