> 中文摘要: MPEG(moving picture expert group)标准目前以及未来都将在多媒体应用中起到越来越重要的作用.提出了一种有效的针对MPEG-1、2码流的索引模型,并详细给出了MPEG流的索引文件生成算法以及基于该模型对码流中的任意帧随机访问显示算法.实验结果表明,该模型可提供对一般的MPEG-1、2码流异常快速的定位访问能力,并可有效地应用于码流中的任意帧随机访问.

Abstract:MPEG standards are playing a more and more important role in many multimedia applications now, and will continue in the future. An effective index model for MPEG-1,2 streams is presented in this paper. Moreover, an algorithm to construct the index for MPEG-1,2 streams is designed, as well as a solution to access any frame in the streams rapidly based on the model. The experimental results have shown the index model can support the ability of postioning a frame in the stream quickly, and it can be applied to access any frame randomly effectively.
