2009/8/13
音视频同步是数字电视广播和多媒体通信等应用的关键技术。该文提出一种基于AVS并结合嵌入技术的音视频同步方法。将压缩音频数据嵌入AVS视频编码系统，保证传输或存储、接收端解码与播放过程中的音视频始终同步。实验结果表明，该方法实现了音视频完全同步，能减小用于同步的开销。
基于AVS的帧内预测模式快速选择算法
帧内预测 模式选择 率失真优化
2009/7/21
AVS视频标准采用率失真优化（RDO）算法来提高帧内预测的压缩性能。但是RDO算法在保证编码图像获得最佳的压缩效率和图像质量的同时给整个编码过程带来了很大的计算量。提出了一种简单有效的AVS1-P2帧内预测模式的快速选择算法。该算法利用相邻块最佳预测模式之间的相关性和块内亮度变化的方向性来缩小候选模式的范围，从而有效节省了编码总时间。实验结果证明，与AVS1-P2的标准参考软件rm52j相比，本算...
