摘要
通过分析当前广电双向网络直播组播视频传输过程中网络传输质量低下时易出现网络抖动而导致用户收看4 K或者高清直播视频出现马赛克的现象,以广州珠江数码集团股份有限公司对此问题提出的解决办法为例,讲述了广州珠江数码如何利用现阶段的有限资源,解决组播直播视频卡顿问题,提高用户观看4 K直播和高清直播体验。希望借此方法为各运营商和广电行业在为提升用户观看4 K直播频道和高清直播频道体验上提供一个有益的参考。
Due to network jitter caused by the low transmission quality in two-way Broadcasting and TV network multicast live transmission,users often encounter mosaic images while watching 4K or high definition live videos.This paper,taking Guangzhou Digital Media Group as an example,describes how this company solve the choppy live video problems with limited resources and improve users' experience of watching 4k and high-definition live videos.Furthermore,it's expected to provide a reference for operators and broadcasting industry to enhance the experience of watching 4K live and HD live channels.
