The Design and Implementation of a Scalable Wireless Video Streaming System Adopting TCP Transmission Mode

摘要

Streaming services on wireless network is being popular since the bandwidth and QoS on wireless network has been improved. However, the dynamic fluctuated bandwidth, higher error rate and sharp delay jitter on wireless channel cause trouble to the real-time demand of streaming services. The wireless streaming media system aims at mobile users must also consider the large scale number of the potential users and the fast growth in the future. To solve these problems, we propose a scalable wireless video streaming system adopting TCP transmission mode in this paper. Our proposed system is compatible with the RTSP/RTP protocols. It adopts RTP-on-TCP transmission mode to improve the quality of service on wireless network. It takes a hybrid centralized-distributed architecture on the server side to support the growth of users. Streaming services such as VOD are supported by the system with a wide range of media bitrates and several high-performance compression standards such as H264 and AMR.
