| Abstract: | 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. |
