| 摘 要： | 提出一种能降低无线视频广播中视频延时的数据包纠删编码方法.该方法在利用视频接收端反馈信息的基础上,通过考虑视频数据包之间所具有的视频解码依赖性特点,以减少视频延时为目标构造用于视频广播的纠删编码数据包.相比于现有纠删编码,仿真结果表明,该纠删编码方法能使视频接收端获得更小的视频延时.

| Abstract: | A video decoding dependency erasure code is proposed to reduce receiver’s video delay in wireless video broadcast.According to packet receiving status of broadcast receivers,the proposed coding scheme first considers video packets’ decoding dependency,and then constructs coded packets on-the-fly to reduce receiver’s video delay.Simulation shows that the proposed code has lower video delay than the existing erasure codes. |
