摘要
就H.264在无线环境中的传输问题展开研究,针对嵌入式特点对现有的视频传输策略进行了改进,在服务器端引入基于反馈和缓冲驱动的发送端动态传输算法,同时在客户端采用了零缓冲+慢启动的动态实时播放算法。这样可以将网络、缓冲和实时性等加以综合考虑,既保证了视频传输的实时性又提供了一定的网络QoS。且经过实验验证,这两种方法都取得了满意的效果。
H.264 transmission issues in the Wireless LAN were studied and the existing video transmission strategy was improved according to the characteristic of embedded systems.First,a dynamic transmission algorithm based on feedback and buffer-driven was proposed on the server,and then a zero-buffer and slow-start algorithm for dynamic real-time playing was applied on the client.The improved strategy which takes the network,buffer and real-time into account not only ensures the real-time video transmission,but also provides the network QoS.And the experiments show that the two algorithms achieve satisfactory results.
