摘要
随着Internet的迅速发展和流媒体技术的广泛应用,视频的可分级编码已成为一个重要的研究领域。H.264标准是目前最新的国际视频标准,其可分级扩展正在制定过程中。文中根据可分级的3个主要分类,介绍了H.264可分级扩展的主体框架,对其关键技术进行了讨论,最后结合JVT官方参考软件JSVM9.1进行了性能测试,对其应用前景和研究方向进行了分析和展望。
With the development of Intemet and the media streaming, the scalable video coding technique has become an important field of research. In this paper, an overview of the H. 264 Scalable Extension is given with an analysis of temporal, spatial and quality scalability. Their key techniques are discussed. And finally, some experimental results are shown in order to predict the application of scalable video coding by using the latest reference software JSVM_9. 1.
