随着视频压缩编码技术的发展和相关标准的制定,数字视频得到了越来越广泛的应用。而数字视频越来越多的应用需求和应用场景,也刺激着视频压缩技术需要有新的突破和特点。可伸缩视编码技术就是近年来在新的应用需求驱使下产生的新的视频编码技术。不同于传统的视频压缩技术,可伸缩视频编码是一种更多地考虑了网络适应性和灵活性的编码框架。其压缩出的视频流,在一定的带宽范围内都能提供比较好的视频质量,即具有码率、帧率和分辨率等
With the development of video compression coding technology and the development of related standards, digital video has been more and more widely used. The increasing number of digital video applications and application scenarios, but also stimulate the video compression technology requires new breakthroughs and features. Scalable video coding technology is the new video coding technology driven by the new application requirements in recent years. Unlike traditional video compression technologies, scalable video coding is a coding framework that takes into account more network adaptability and flexibility. The compressed video stream, in a certain bandwidth can provide better video quality, that is, with the code rate, frame rate and resolution, etc.
