MPEG-2 is considered important because it has been chosen as the compression scheme for over-the-air digital television ATSC, DVB and ISDB, digital satellite TV services like Dish Network, digital cable television signals, SVCD and DVD Video.

One is the MPEG transport stream, designed to carry digital video and audio over possibly lossy media, where the beginning and the end of the stream may not be identified, such as broadcasting or magnetic tape, examples of which include ATSC / DVB / ISDB / SBTVD broadcasting, and HDV recording on tape.

NTSC was the first widely adopted broadcast color system and remained dominant where it had been adopted until the first decade of the 21st century, when it was replaced with digital ATSC.

Standards that support digital SDTV broadcast include DVB, ATSC and ISDB.

It may also be used in digital transmission, such as the ATSC standardized 8-VSB.

For example, in North America, " channel 2 " refers to the broadcast or cable band of 54 to 60 MHz, with carrier frequencies of 55. 25 MHz for NTSC analog video ( VSB ) and 59. 75 MHz for analog audio ( FM ), or 55. 31 MHz for digital ATSC ( 8VSB ).

Many television stations are now in the process of converting from analogue ( NTSC, PAL or SECAM ) broadcast, to digital TV ( ATSC broadcast, DVB or ISDB ).

D-VHS can record up to 4 hours of ATSC digital television in 720p or 1080i formats using the fastest record mode ( equivalent to VHS-SP ), and up to 40 hours of standard definition video at slower speeds.

ATSC and digital cable standards limit AC-3 to 448 kbit / s.

WQWQ is a low-power station whose analog signal was never available over the air in Dahlgren ; however, it is available as ATSC digital channel 12. 2.

8VSB is the modulation method used for broadcast in the ATSC digital television standard.

While it is not technically part of the ATSC or DVB broadcast standards as of yet, reports suggest that higher progressive frame rates will feature in the next-generation high-definition television broadcast standards.

ATSC and DVB-T specify the modulation used for over-the-air digital television ; by comparison, QAM is the modulation method used for cable.

While NTSC and most other analog television systems also use a vestigial sideband technique, the unwanted sideband is filtered much more effectively in ATSC 8VSB transmissions.

ATSC digital television is affected by wind and trees ( even if not surrounding the transmitter or receiver locations ), apparently related to its use of 8VSB modulation instead of COFDM.

In North America a specification laid out by the ATSC has become the standard for digital terrestrial television.

The Advanced Television Systems Committee ( ATSC ) standards body in the United States approved the use of H. 264 / AVC for broadcast television in July 2008, although the standard is not yet used for fixed ATSC broadcasts within the United States.

Digital radio and digital television can also be received, however there is much greater difficulty with reception of weak signals due to the cliff effect, particularly with the ATSC TV standard mandated in the U. S. For DVB-T, hierarchical modulation may allow a lower-definition signal to be received even if the details of the full signal cannot be decoded.

ATSC standards are a set of standards developed by the Advanced Television Systems Committee for digital television transmission over terrestrial, cable, and satellite networks.

The high definition television standards defined by the ATSC produce wide screen 16: 9 images up to 1920 × 1080 pixels in size — more than six times the display resolution of the earlier standard.

ATSC replaced much of the analog NTSC television system in the United States on June 12, 2009, replaced NTSC on August 31, 2011 in Canada, and will replace NTSC by December 31, 2015 in Mexico, January 1, 2019 in El Salvador., and by end of 2012 in South Korea.

Although the ATSC A / 53 standard limits MPEG-2 transmission to the formats listed below ( with integer frame rates paired with 1000 / 1001-rate versions ), the U. S. Federal Communications Commission declined to mandate that television stations obey this part of the ATSC's standard.

The standard for signal transmission over digital cable television systems in the United States is now fixed as both 64-QAM and 256-QAM ( Quadrature Amplitude Modulation ), which is specified in SCTE 07, and is part of the DVB standard ( but not ATSC ).

In the United States, new television receivers using the ATSC standard were supposed to incorporate this functionality by July 1, 2005.

It has been adopted in many broadcast formats including all North American digital television ( ATSC ), DVB-T, direct broadcast satellite, cable television, DTMB, IPTV, and surround sound radio services.

CITY launched a test broadcast of its digital signal using the ATSC DTV standard on January 16, 2003, and began regular digital transmission on March 3 of the same year, becoming the first digital television station in Canada.

With the new antenna, the tower became capable of broadcasting high-definition digital television signals using the DVB-T standard ( which is the European counterpart to the ATSC digital standard used in the United States ).

North America, parts of Central America, and South Korea are adopting the ATSC standards, while other countries are adopting or have adopted other standards.

* ATSC standards

In summer of 2005, the ATSC published standards for Enhanced VSB, or E-VSB.

* Likewise, use of digital broadcasting standards such as the DVB and ATSC eliminates the issues introduced by modulation and demodulation of analogue signals.

The ATSC standards were developed in the early 1990s by the Grand Alliance, a consortium of electronics and telecommunications companies that assembled to develop a specification for what is now known as HDTV.

ATSC standards are marked A / x ( x is the standard number ) and can be downloaded freely from the ATSC's website at ATSC. org.

As with other systems, ATSC depends on numerous interwoven standards, e. g. the EIA-708 standard for digital closed captioning, leading to variations in implementation.

The differences between the bandwidths exist because European cable TV conforms to PAL standards of 8 MHz bandwidth and North American cable TV conforms to ATSC standards which specify 6 MHz.

The ATSC standards include a provision for 16-VSB transmission over cable at 38. 4 Mbit / s, but the encoding has not yet gained wide acceptance.

Advanced Television Standards Committee created the ATSC standards that use an ATSC tuner in North America and South Korea — an evolution from the analog National Television Standards Committee ( NTSC ) standard.

Different tuners are used for different television standards such as PAL, NTSC, ATSC, SECAM, DVB-C, DVB-T, ISDB, T-DMB, open cable.

This " notch " pulls its service contour in that direction back to Stockbridge instead of McDonough, however + even with just 3 kW ( equivalent to 15 kW analog, by FCC standards for ATSC ) it was predicted to reach much further in all directions than its most recent ( since mid-2007 ) 55 kW analog, though ATSC predictions are almost always more than actual reception.
