摘要
结合不同图像帧的重要性差异及视频数据分割原则,提出一种基于帧间层次的视频码流划分方案,对划分所得各类信息进行了不平等差错保护仿真实验,仿真结果表明,所采用的层次划分方式相比传统的基于图像帧的划分方式经不等差错保护后,视频恢复效果具有一定的优越性。
An frame hierarchy based video stream division scheme is proposed, which is combined with the dif- ferent importance of video frame and video division principles. The division information is protected by unequal error protection in simulations. The simulation results show that the proposed division scheme excels the traditional video frame division scheme.
