Distributed Video Streaming with Forward Error Correction
With the explosive growth of video applications over the Internet, many approaches have been proposed to stream video effectively over packet switched, best-effort networks. Many use techniques from source and channel coding, or implement transport protocols, or modify system architectures in order to deal with delay, loss, and time-varying nature of the Internet. In our previous work , we prop...
متن کاملAn Adaptive Forward Error Correction Algorithm for Streaming Video
Video applications over network are often disturbed by data packet loss or errors as well as the insufficiency of network bandwidth. Some related studies have demonstrated that in many cases, the fluctuation of network bandwidth and packet loss rate are two key factors that influence the quality of video streaming. Therefore for guaranteeing video quality, FEC (forward error correction) can be ...
متن کاملPacketization Schemes for Forward Error Correction in Internet Video Streaming
In this work, our focus is on video streaming applications with relatively strict delay constraints; for such applications, forward error correction (FEC) is the preferred channel coding technique to recover from packet losses. Moreover, since video packets are usually of different importance, optimal bit allocation across video packets results in different packets receiving unequal error prote...
متن کاملRepair of Streaming Multimedia with Adaptive Forward Error Correction
Internet multimedia applications have timing constraints that are often not met by TCP, the de facto Internet transport protocol, hence, most multimedia applications use UDP. Since UDP does not guarantee data arrival, UDP flows often have high data loss rates. Network data loss can be ameliorated by the use of Forward Error Correction (FEC), where a server adds redundant data to the flow to hel...
متن کاملBandwidth Aggregation with Path Interleaving Forward Error Correction Mechanism for Delay-Sensitive Video Streaming in Wireless Multipath Environments
Multipath transmission which uses multiple paths for data transfer has been used in wireless networks to improve the performance of end-to-end transmission. However, wireless networks suffer from high packet loss rate, variations in end-to-end delay and available bandwidth. Hence, the Forward Error Correction (FEC) mechanism has been proposed to recover lost packets by adapting to the changing ...
