随着网络带宽的提高、智能终端和互联网音视频应用数量的迅猛增长,视频流量已经成为网络传输的主要流量,持续增长的视频流量不仅给网络传输带来了巨大挑战,也带来了海量存储的要求。为了能够传输和存储海量的视频数据,作为音视频应用的基础技术,视频压缩编码在快速地发展。我国在图像和视频编码技术方面有多年的研究历史,但早期在国际标准制定中的参与度不高,标准技术几乎全部为国外若干公司所垄断,2002年成 With the increase of network bandwidth, the rapid growth of the number of intelligent terminals and Internet audio-video applications, video traffic has become the main traffic of network transmission. The continuous increase of video traffic not only poses great challenges to network transmission, but also brings mass storage Request. In order to be able to transmit and store large amounts of video data, as the basic technology of audio and video applications, video compression coding is rapidly developing. China has many years of research history in image and video coding technology. However, its early involvement in international standards development was not high. Almost all of the standard technologies were monopolized by a number of foreign companies. In 2002,
