The following tables show the frequencies assigned to analog broadcast television channels in various regions of the world, along with the ITU letter designator for the system used. The frequencies shown are for the analog video and audio carriers. The channel itself occupies several megahertz of bandwidth. For example, North American channel 1 ...
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.
In March 2008, the FCC requested public comment on turning over the bandwidth occupied by analog television channels 5 and 6 (76–88 MHz) to extend the FM broadcast band when the digital television transition was to be completed in February 2009 (ultimately delayed to June 2009). [8]
Digital cable channels typically are allocated above 552 MHz, the upper frequency of cable channel 78. (Cable channels above channel 13 are at lower frequencies than UHF broadcast channels with the same number, as seen in North American cable television frequencies .)
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 following chart lists frequencies on the broadcast company band, and which classes broadcast on these frequencies; Class A and Class B, 10,000 watt and higher (full-time) stations in North America which broadcast on clear-channel station frequencies are also shown.
In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.
A television channel, or TV channel, is a terrestrial frequency or virtual number over which a television station or television network is distributed. For example, in North America , channel 2 refers to the terrestrial 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 ...
