QoS Research of H.264 Video Transmission in Embedded Wireless LAN
嵌入式无线局域网中H.264视频传输的QoS研究

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.
