Abstract

Digital video broadcasting-terrestrial (DVB-T) is important occasion in these days. But HDTV broadcasting is not widely used in Europe in DVB-T nets due high bandwidth requirements. Several solutions of this problem are discussed in this paper. Scalable video coding is the first choice but not very useful. MPEG-4 AVC coding algorithm brings a lot of new features and better compression efficiency also. But differential frame coding is going further. Proposed method can handle a problem with migration from Standard Definition (SD) to High Definition (HD) resolution and saving of the bandwidth in DVB-T nets.

当前数字视频广播中从标清到高清的迁移

数字地面视频广播(DVB-T)是当今重要的应用领域。但HDTV广播由于带宽要求高，在欧洲的DVB-T网络中并没有得到广泛应用。本文讨论了这一问题的几种解决方法。可扩展视频编码是首选，但不是很有用。MPEG-4 AVC编码算法带来了许多新的特性和更好的压缩效率。但是差分帧编码走得更远。该方法可以解决DVB-T网络中从标清(SD)分辨率向高清(HD)分辨率迁移的问题，并节省带宽。
