What are the digital TV standards?
The major digital TV (DTV) standards are ATSC (North America), DVB (Europe) and ISDB (Japan). All three use MPEG-2 video compression and Dolby Digital audio compression.
DTV programs can be transmitted as either standard-definition television (SDTV) or high-definition television (HDTV). SDTV programs are broadcast as 480-line interlaced (480i) or progressive-scan (480p) video. HDTV programs are broadcast either in the 1080-line interlaced (1080i) or 720-line progressive (720p) formats, always with a wide screen picture.
All three digital television transmitting systems use the same algorithm used in DVDs to encode the image, MPEG-2. These three standards vary mainly in the video format before and after the encoding, and the way the audio is encoded.
In July 2008, the ATSC standards were amended to incorporate H.264/MPEG-4 AVC compression and 1080p at 50, 59.94 and 60fps (1080p50 and 1080p60).
Since September 2009, ETSI and EBU, the maintainers of DVB, added support for 1080p50 signal coded with MPEG-4 AVC High Profile Level 4.2 with Scalable Video Coding extensions or VC-1 Advanced Profile compression. DVB also supports 1080p encoded at ATSC frame rates of 23.976, 24, 29.97, 30, 59.94 and 60.
