Combined with Unrestricted Motion Vector(UMV) mode advanced prediction mode can be used to improve the prediction performance and reduce the blocking effects. 高级预测模式可与无限制运动向量模式一起使用以提高预测性能及降低方块效应。
Motion estimation uses not only traditional technology but also some new technology, which have been used in H.263 standard such as unrestricted motion vector mode half sample search and so on. 运动编码在传统方法基础上做了改进,如半象素搜索、无限的运动失量、高级预测方式等;
