At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television ...
Channel numbers in ATSC do not correspond to RF frequency ranges, as they did with analog television. Instead, virtual channels , sent as part of the metadata along with the program(s), allow channel numbers to be remapped from their physical RF channel to any other number 1 to 99, so that ATSC stations can either be associated with the related ...
An example of the ATSC major and minor numbers would be to have main programming airing on say channel 8 (the "major channel") with analog on 8.0 and digital on 8.1 (the first two "minor channels") with other entertainment channels below 8.99 on channels 8.2, 8.3, and up and informational data channels ranging from 8.100 to 8.999.
The five main ATSC formats of DTV currently [when?] broadcast in the U.S. are: . Standard definition—480i, to maintain compatibility with existing NTSC sets when a digital television broadcast is converted back to an analog one [citation needed] —either by a converter box or a cable/satellite operator's proprietary equipment
The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
Digital-television radio, DTV radio, or DTR describes the audio channels that are provided with a digital television service. [1] These channels are delivered by cable television, direct-broadcast satellite or digital terrestrial television.
