Television network

networknetwork televisionTV network
A television channel is a terrestrial frequency or virtual number over which a television station or television network is distributed.
In countries where most networks broadcast identical, centrally originated content to all of their stations and where most individual television transmitters therefore operate only as large "repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency) and "television station" have become mostly interchangeable in everyday language, with professionals in television-related occupations continuing to make a differentiation between them.

Analog television

analoganalogueanalogue television
Depending on the multinational bandplan for a given regional n, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well.
The transmission system must include a means of television channel selection.

Digital subchannel

subchanneldigital multicastsubchannels
Digital terrestrial television channels are the same as their analog predecessors for legacy reasons, however through multiplexing, each physical radio frequency (RF) channel can carry several digital subchannels.
A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx").

NTSC

analogNTSC-M30p
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 audio (FM), or 55.31 MHz for digital ATSC (8VSB).
An NTSC television channel as transmitted occupies a total bandwidth of 6 MHz.

Channel (broadcasting)

ChannelChannelsfrequency channel
A television channel is a terrestrial frequency or virtual number over which a television station or television network is distributed.
In broadcasting, a channel or frequency channel is a designated radio frequency (or, equivalently, wavelength), assigned by a competent frequency assignment authority for the operation of a particular radio station, television station or television channel.

BBC One

BBC1BBC 1BBC
This terminology may be muddled somewhat in other jurisdictions, for instance Europe, where terrestrial channels are commonly mapped from physical channels to common numerical positions (i.e. BBC One does not broadcast on any particular "channel 1" but is nonetheless mapped to the "1" input on most British television sets).
BBC One (or BBC1 and BBC 1) is the first and flagship television channel of the BBC in the United Kingdom, Isle of Man and Channel Islands.

Television station

television stationsTV stationstation
Commonly, the term "television channel" is used to mean a television station or its pay television counterpart (both outlined below).
Television stations broadcasting over an analog system were typically limited to one television channel, but digital television enables broadcasting via subchannels as well.

Multiplexing

Digital terrestrial television channels are the same as their analog predecessors for legacy reasons, however through multiplexing, each physical radio frequency (RF) channel can carry several digital subchannels.
Cable TV has long carried multiplexed television channels, and late in the 20th century began offering the same services as telephone companies.

Terrestrial television

Broadcastover-the-airterrestrial
Traditionally, TV stations made their broadcasts by sending specially-encoded radio signals over the air, called terrestrial television.
Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and UHF bands.

Radio receiver

A television station is a type of terrestrial station that broadcasts both audio and video to television receivers in a particular area.

Communication channel

Individual television stations are usually granted licenses by a government agency to use a particular section of the radio spectrum (a channel) through which they send their signals.

ATSC standards

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 audio (FM), or 55.31 MHz for digital ATSC (8VSB).
The reduced bandwidth requirements of lower-resolution images allow up to six standard-definition "subchannels" to be broadcast on a single 6 MHz TV channel.

A television station is a type of terrestrial station that broadcasts both audio and video to television receivers in a particular area.
At first, terrestrial broadcasting was the only way television could be widely distributed, and because bandwidth was limited, i.e., there were only a small number of channels available, government regulation was the norm.

Barker channel

A barker channel is a form of digital signage, operating in the form of a television channel that is entirely composed of sales promotion and advertising, usually marketing various features of the service carrying the channel.
