Next generation network(NGN) is an All-IP based heterogeneous network which includes wired network, satellite network, wireless mobile network and so on. Comparing with the traditional wired network, in NGN, the classical TCP/IP is beginning to show signs of age. In order to cope with problems such as the poor performance of wireless links and mobile terminals, including the high error rate of wireless...
With the development of the wireless communications technology and the multimedia technology, the wireless internet multimedia transport of real-time becomes an important applications field. We will meet a problem that the distinguish of the status of package loss is not very good which will affect the QoS when we transport multimedia data in wireless internet. Based on this problem the article comes...
This paper proposes an idiographic implement scheme of MPEG-4 real-time video streaming for multi-channel based on RTP/RTCP over WLAN. It also proposes an effective synchronistic model for multi-channel video based on timestamp synchronization. Aiming at the wireless QoS mechanism, this system applies to an ECN algorithm based on RTCP feedback rate control algorithm-TFRC. The ECN algorithm improves...
