An analysis on the mainstreams of adaptive bitrate streaming technologies

With the rapid growth of Internet multimedia applications, especially the development of online video services, the traditional streaming media technology because of its single encoding mode is difficult to adapt to the changes of user network, has a great impact on the user experience. This paper analyzes the main problems of the online video business faced, and introduces the characteristics and advantages of the emerged adaptive bit rate streaming technology. Through the analysis and comparison of adaptive bit rate streaming and traditional streaming technology, it is indicated that for online video, particularly OTT video, the standard adaptive bit rate streaming technology, which helps unify infrastructure and consumer electronics configurations, is much superior to the traditional one.
