视频通信中的应用层前向纠错技术
Application layer forward error correction technology in video communication
摘要
Abstract
In order to ensure the quality of video effect under the condition of limited channel bandwidth, an application layer forward error correction scheme for video broadcast in wireless networks is proposed. The proposed scheme assigns each video packet a different priority according to their contribution to the reconstructed video quality, makes full utilization of this characteristic. The scheme takes all the terminals into consideration and aims at im-proving the overall received video quality by sacrificing the quality of terminals with low packet loss probability. Simulation results showed that the proposed scheme can achieve 2-5 dB average PSNR enhancement compared with the EEP and EW schemes.关键词
