Television channel frequencies

From Wikipedia, the free encyclopedia
Tables of radio frequencies assigned to television channels

The following tables show thefrequencies assigned to analog broadcast television channels in various regions of the world, along with theITU letter designator for the transmission system used. The frequencies shown are for the channel limits and for the analog video and audiocarriers. The channel itself usually occupies 6, 7 or 8megahertz ofbandwidth depending on the television transmission system in use. For example, North American channel 1 occupies the spectrum from 44 to 50 MHz. SeeBroadcast television systems for a table of signal characteristics, including bandwidth, byITU letter designator. Analog television broadcasts have been phased out in most regions, having been replaced bydigital television broadcasts.

International normalization for analog TV systems

[edit]
Analog television system by nation

International broadcasting television frequencies are divided in two part of the spectrum; theVery high frequency or "VHF" band and theUltra high frequency or "UHF" band.

VHF

[edit]
A plan showing frequency ranges for each television channel used on VHF

Americas (most countries), South Korea, Taiwan, Myanmar, and the Philippines

[edit]
Main article:Pan-American television frequencies § Terrestrial television

During World War II, the frequencies originally assigned as channels 13 to 18 were appropriated by the U.S. military, which still uses them to this day. It was also decided to move the allocation for FM radio from the 42-50 MHz band to a larger 88-106 MHz band (later extended to the current 88-108 MHz FM band). This required a reassignment of the VHF channels to the plan currently in use.[1]

Assignments since February 25, 1946

  • FM channel 200, 87.9 MHz, overlaps TV 6. This is used only byK200AA.
  • TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel E4A or channel IC, but at lower volume thanwideband FM broadcast stations, because of the lower deviation.
  • Channel 1 audio is the same as European Channel E2 audio and the video is the same as European Channel E2A. Channel 2 video is the same as European Channel E3 video.

  • Channel A was never used terrestrially. The only System IBand I transmitter on Channel B wasRTÉ One from theMaghera, Co. Clare transmitter during 1963–1999. Channel A was initially intended for use at Maghera but Channel B was used instead because of the risk of interference to (overspill) reception ofBBC405 line transmissions.[2] It was moved to Channel E due to interference from distant transmitters on channel E3 and Italian channel IA viacertain atmospheric conditions and other reasons. Channel C was used by a relay transmitter in Glanmire, Co. Cork.
  • Channel B video is the same as Italian Channel IA video and Channel C audio is the same as Channel E4 audio.
  • There are currently no Band I Channels used in Ireland (except on cable TV, and these have mostly been phased out forDOCSIS use) and no plans to resume using them.
  • Most Irish Cable TV systems do not follow the above channel plan as their analogue (video) carriers are usually at multiples of 8 MHz (i.e. 176, 184, 192 MHz etc. in Band III)

Western Europe; Greenland; and most countries in Asia, Africa, and Oceania

  • Channels 1 and 1A were used for early experimental broadcasts and are no longer allocated.[3]
  • Channels 15 and 16 are allocated for use in the African Broadcasting Area only.[4]
  • Channel 2A was only ever used in Austria for theSendeturm Jauerling to avoid interferences with neighboring Eastern European TV stations.
  • Channel 3 inBelgium,RTBF 1 broadcast from the Liège transmitter with 100 kW until the switchover toDVB-T.
  • Channel 12 was reserved by the military in some countries (likeGermany (West Germany only)) so only relay transmitters operated on this frequency.
  • Channel 4A audio carrier's frequency is very close to US Channel 6 audio carrier and overlaps the FM band in Europe.

  • Channels A through H are indicated in many European TVs as Channels 13–20.
  • Channels B, C, D, H, H1, and H2 are identical to Channels E4, E4A, E5, E10, E11, and E12, respectively.
  • Channel A video carrier is the same as Channel E2 audio carrier and thus it used to be common that the audio from a distant TV station on channel E2 received viaSporadic E interferes with Channel A video and vice versa.
  • Channel C audio carrier's frequency falls into the FM band in Europe, and is also identical to American A6 channel audio.

UHF

[edit]

Americas (most countries), South Korea, Taiwan, Burma (Myanmar) and the Philippines

[edit]

For frequencies used in the Americas (most countries), South Korea, Taiwan and the Philippines, refer toPan-American television frequencies.

Notes
  • The frequencies used by UHF channels 70 through 83 were reallocated to theLand Mobile Radio System (Public Safety andTrunked Radio) andmobile phones in a CCIR worldwide convention in 1982, and thus were never used for digital TV but are highlighted in cyan and listed here for theoretical use.
  • In certain metropolitan areas of the United States, Channels 14 through 20 have been allocated to Land Mobile Radio (LMR) use.[12]
  • Channels 52 through 69 in the United States have beenreallocated now that conversion to digital TV was completed on June 12, 2009. These channels are highlighted in yellow. Channels 70 through 83 in the United States and Canada were re-allocated toAMPS cellular phone use in 1983.
  • On August 22, 2011, the United States'Federal Communications Commission announced a freeze on all future applications for broadcast stations requesting to use channel 51,[13] to preventadjacent-channel interference to the A-Block of the 700 MHz band. Later that year (on December 16, 2011),Industry Canada and theCRTC followed suit in placing a moratorium on future television stations usingChannel 51 for broadcast use, to preventadjacent-channel interference to the A-Block of the 700 MHz band.[14]
  • Not all countries listed useATSC, which has a singleVSBcarrier wave. Other countries useCOFDM modulation forDVB-T (Taiwan, Colombia, Panama) orISDB-Tb (Philippines and Latin America), which has dozens of carriers within the channel. Burma (Myanmar) uses DVB-T2 on 8 MHz channel spacing on Western Europe / Asia DTV frequency along with Southeast Asian countries (except Philippines).[15]
  • ISDB-Tb frequency DTV channel 14 uses 473.142857 MHz, butATSC 3.0,DVB-T/DVB-T2, andDTMB, use 473.0 MHz.
  • Channel 37 is reserved forradio astronomy in the United States, Canada,Bermuda,Belize, andthe Bahamas, thus there are notelevision stations assigned to it. Mexico also informally observes a ban on transmitters using this channel.
  • Due to theFCC repack in theUnited States, all TV stations that had been broadcasting from channels 38 to 51 were required to move on or below channel 36 by July 3, 2020. As a result, channels 38-51 are highlighted in magenta.[16] These frequencies would later be used by U.S. mobile carriers likeT-Mobile on Band 71.[17]
