Experimental results show that multi-reference-frame prediction does not improve coding performance but involve heavy computing cost in most cases.

实验结果表明，多参考帧预测在绝大多数情况下不能改善编码效率，反而引入了繁重的计算开销。

The characters of the VOV reference frame are multi-viewpoint observation, visual description, concept centered, process direction and model drive.

主要特征是多视点观察、可视化描述、概念为中心、过程为导向、模型做驱动。

But regarding the rapid change's sequence of movement background, using the multi-reference frame technology influence to be obvious regarding to code the performance.

而闭于于活动背景敏捷变更的序列，长参考帧的当用闭于于编码机能的影响较大。
