摘要
移动多媒体业务是当前移动数据通信的研究热点。视频信号处理需要大量的运算,要求较宽的传输带宽。目前移动网络上的视频传输存在着网络带宽有限、误码严重、终端处理能力较弱等问题。基于H.263提出了提高编码效率、增强抗干扰能力的编解码算法优化方案,有效地提高了运算效率,提升了解码视频的主客观质量。
Multimedia services over mobile network have received much attention recently.Video transmission needs high bandwidth.While the limited bandwidth of mobile network along with high error rates becomes the bottleneck.For wireless video transmission,based on ITU-T H.263,an optimized scheme to increase encode efficiency and enhance error resilience is presented.And experimental results also show that the improvement is efficient and effective.
