From Standard Definition to High Definition Migration in Current Digital Video Broadcasting

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.
