广播电视行业经过几十年的发展,积累下来了很多非常优秀的音视频资料。这些资料都具有非常重要的历史意义,是广播电视行业最为宝贵的一种媒体资产,如何将这些媒体视频资产进行有效的数字压缩编码进行管理和保护,是广播电视行业极为迫切的需求,伴随着计算机技术的高速发展,各研究机构不断开发出各种高效率的视频压缩编码技术,本文重点分析了当前主流的几种视频压缩技术原理及算法,并对各类编码技术进行了比对,从中选取出更加适合广播电视行业的视频压缩编码技术,为提高工作效率、开展多项视频业务奠定了基础。
After decades of development, the radio and television industry has accumulated a lot of very good audio and video materials. These materials have very important historical significance and are one of the most valuable media assets in the radio and television industry. How to manage and protect these media video assets effectively through digital compression coding is an extremely urgent need in the radio and television industry. The rapid development of computer technology, research institutions continue to develop a variety of high-efficiency video compression coding technology, the paper focuses on the analysis of several mainstream video compression technology principles and algorithms, and various types of coding technology were compared, from Select more suitable for the broadcast video industry, video compression coding technology, in order to improve work efficiency, to carry out a number of video services laid the foundation.
