本发明所描述的技术涉及方法、设备及电脑可读机制，其用于接收压缩视频数据，其中压缩视频数据与信息框集相关。译码器侧预测子细分技术用于计算用于来自于信息框集的当前信息框的新运动矢量，其中新运动矢量基于一个或者多个参考信息框评估用于当前信息框的运动。自运动矢量寄存器中检索出与不同信息框相关的已有运动矢量。基于该已有运动矢量，使用译码器侧运动矢量预测技术计算新运动矢量，以使得已有运动矢量处于在计算新运动矢量之后的运动矢量寄存器中。

The techniques described herein relate to methods, apparatus, and computer readable media configured to receive compressed video data, wherein the compressed video data is related to a set of frames. A decoder-side predictor refinement technique is used to calculate a new motion vector for a current frame from the set of frames, wherein the new motion vector estimates motion for the current frame based on one or more reference frames. An existing motion vector associated with a different frame from a motion vector buffer is retrieved. The new motion vector is calculated based on the existing motion vector using a decoder-side motion vector prediction technique, such that the existing motion vector is in the motion vector buffer after calculating the new motion vector.
