【摘要】 针对无线网络带宽波动大、误码率高的特点,提出一种基于FGS和UEP的无线视频传输方案.利用FGS码流的特点,适应无线信道质量的变化;同时根据信道反馈信息,提出了视频数据分级保护策略,对不同的视频数据采取不同的保护力度,提高了视频传输的质量.更多还原

【Abstract】 A scheme for wireless video transmission based on FGS and unequal error protection was proposed,for the features in wireless network,including the high transmission error ratio.In order to improve the video transmission quality,this scheme employs FGS bit-streams powerful bandwidth adaptation ability for the fluctuation of bandwidth of wireless network,and proposes an unequal protection scheme for the high transmission error ratio.更多还原
