45-615: Brit Asia TV Network is a British television channel that is aimed at the British Asian audience. It launched in 2008 and is known for the Brit Asia TV Music Awards . The channel is available on satellite and publishes videos on Dailymotion and YouTube . Between June 2017 and January 2020 the channel was also available on Virgin Media cable. In August 2017 the channel outsourced its playout operations to ABS Broadcasting. In 2017

90-459: A distributor like TNT may start producing its own programming, and shows presented exclusively on pay-TV by one distributor may be syndicated to terrestrial stations. The cost of creating a nationwide channel has been reduced and there has been a huge increase in the number of such channels, with most catering to a small group. From the definitions above, use of the terms network or station in reference to nationwide cable or satellite channels

135-560: A letter to the editor of Wireless Engineer in 1942. For example, the approximate geometric mean of band 7 is 10 MHz, or 10  Hz. The band name "tremendously low frequency" (TLF) has been used for frequencies from 1–3 Hz (wavelengths from 300,000–100,000 km), but the term has not been defined by the ITU. Frequency bands in the microwave range are designated by letters. This convention began around World War II with military designations for frequencies used in radar , which

180-483: A move to 2.4 GHz spread spectrum RC control systems. Licensed amateur radio operators use portions of the 6-meter band in North America. Industrial remote control of cranes or railway locomotives use assigned frequencies that vary by area. Radar applications use relatively high power pulse transmitters and sensitive receivers, so radar is operated on bands not used for other purposes. Most radar bands are in

225-520: A result of being in attendance they confirmed the deal for a collaboration then. In 2019, Brit AsiaTV has announced an exciting new partnership with the Official Charts Company, in launching the world's first Official Punjabi Chart Show. Punjabi music consumption has grown exponentially over the last few decades, cementing itself as the dominant South Asian music genre across India. With the roots of modern-day Punjabi music firmly entrenched in

270-407: A traditional name. For example, the term high frequency (HF) designates the wavelength range from 100 to 10 metres, corresponding to a frequency range of 3 to 30 MHz. This is just a symbol and is not related to allocation; the ITU further divides each band into subbands allocated to different services. Above 300 GHz, the absorption of electromagnetic radiation by Earth's atmosphere

315-549: 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 audio ( FM ), or 55.31 MHz for digital ATSC ( 8VSB ). Channels may be shared by many different television stations or cable-distributed channels depending on

360-431: Is a fixed resource which is in demand by an increasing number of users, the radio spectrum has become increasingly congested in recent decades, and the need to utilize it more effectively is driving modern telecommunications innovations such as trunked radio systems , spread spectrum , ultra-wideband , frequency reuse , dynamic spectrum management , frequency pooling, and cognitive radio . The frequency boundaries of

405-420: Is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands. For example, broadcasting, mobile radio, or navigation devices, will be allocated in non-overlapping ranges of frequencies. For each radio band,

450-517: Is an annual event held by the channel which has seen some of the biggest artists perform at some of the biggest venues in the world. In 2018 the awards were held in Wembley Arena which saw Sidhu Moose Wala , Mist (rapper) & Stefflon Don . headline with the track 47 produced by Steel Banglez . It was reported that both Banglez and Sidhu Moose Wala met at the Punjabi Film awards in 2018 and as

495-436: Is nonetheless mapped to the 1 input on most British television sets). On digital platforms, such (location) channels are usually arbitrary and changeable, due to virtual channels . A television station is a type of terrestrial station that broadcasts both audio and video to television receivers in a particular area. Traditionally, TV stations made their broadcasts by sending specially-encoded radio signals over

540-418: Is possible to use adjacent channels only because they are all at the same power, something which could only be done terrestrially if the two stations were transmitted at the same power and height from the same location . For DTT, selectivity is inherently better, therefore channels adjacent (either to analog or digital stations) can be used even in the same area . Commonly, the term television channel

585-478: Is so great that the atmosphere is effectively opaque, until it becomes transparent again in the near-infrared and optical window frequency ranges. These ITU radio bands are defined in the ITU Radio Regulations . Article 2, provision No. 2.1 states that "the radio spectrum shall be subdivided into nine frequency bands, which shall be designated by progressive whole numbers in accordance with

630-474: Is technically inaccurate. However, this is an arbitrary, inconsequential distinction, and varies from company to company. Indeed, the term cable network has entered into common usage in the United States in reference to such channels, even with the existence of direct broadcast satellite . There is even some geographical separation among national pay television channels in the U.S., be it programming (e.g.,

675-552: Is used in coastal waters and relatively short-range communication between vessels and to shore stations. Radios are channelized, with different channels used for different purposes; marine Channel 16 is used for calling and emergencies. Amateur radio frequency allocations vary around the world. Several bands are common for amateurs worldwide, usually in the HF part of the spectrum. Other bands are national or regional allocations only due to differing allocations for other services, especially in

720-691: Is used to mean a television station or its pay television counterpart (both outlined below). Sometimes, especially outside the U.S. and in the context of pay television, it is used instead of the term television network , which otherwise (in its technical use above) describes a group of geographically-distributed television stations that share affiliation / ownership and some or all of their programming with one another. 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

765-509: The Bally Sports group of regional sports channels, which share several programs), or simply regionalized advertising inserted by the local cable company. Should a legal distinction be necessary between a (location) channel as defined above and a television channel in this sense, the terms programming service (e.g. ) or programming undertaking (for instance, ) may be used instead of the latter definition. Bandplan Different parts of

810-565: The ITU and the local regulating agencies like the US Federal Communications Commission (FCC) and voluntary best practices help avoid interference. As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 ) metres, with corresponding frequency of 3×10   hertz , and each covering a decade of frequency or wavelength. Each of these bands has

855-535: The VHF and UHF parts of the radio spectrum. Citizens' band radio is allocated in many countries, using channelized radios in the upper HF part of the spectrum (around 27 MHz). It is used for personal, small business and hobby purposes. Other frequency allocations are used for similar services in different jurisdictions, for example UHF CB is allocated in Australia. A wide range of personal radio services exist around

900-748: The data rate that can be transmitted. Below about 30 kHz, audio modulation is impractical and only slow baud rate data communication is used. The lowest frequencies that have been used for radio communication are around 80 Hz, in ELF submarine communications systems built by a few nations' navies to communicate with their submerged submarines hundreds of meters underwater. These employ huge ground dipole antennas 20–60 km long excited by megawatts of transmitter power, and transmit data at an extremely slow rate of about 1 bit per minute (17 millibits per second , or about 5 minutes per character). The highest frequencies useful for radio communication are limited by

945-529: The far infrared and mid infrared bands. Because it is a fixed resource, the practical limits and basic physical considerations of the radio spectrum, the frequencies which are useful for radio communication , are determined by technological limitations which are impossible to overcome. So although the radio spectrum is becoming increasingly congested, there is no possible way to add additional frequency bandwidth outside of that currently in use. The lowest frequencies used for radio communication are limited by

990-485: The BritAsia TV Punjabi Film Awards (PFA) on Saturday, March 30, 2019.The awards celebrated the very best of Punjabi Films during 2018. There were also awards for special recognition and outstanding achievement on the night. The event saw the likes of Steel Banglez , Jaz Dhami , Sonam Bajwa , Gippy Grewal , Sidhu Moosewala , Harbhajan Mann , Binnu Dhillon in attendance. Brit Asia TV Music Awards

1035-456: The ITU has a band plan (or frequency plan ) which dictates how it is to be used and shared, to avoid interference and to set protocol for the compatibility of transmitters and receivers . Each frequency plan defines the frequency range to be included, how channels are to be defined, and what will be carried on those channels. Typical definitions set forth in a frequency plan are: The actual authorized frequency bands are defined by

1080-517: The Punjabi Film Awards to support and acknowledge the contributions made by Punjabi Cinema, the first of its kind to be held outside of India. The event saw some of the biggest names from Punjabi Music and Cinema attend such as Gippy Grewal , Sharry Mann , Gurpreet Ghuggi , Satinder Sartaaj , Tarseem Jassar , Jasmin Sandlas and more. The JW Mariott Grosvenor House Hotel London played host to

1125-482: The UK, BritAsia TV will be working alongside the Official Charts Company to establish the first Punjabi music chart in the world compiled using official data from all major streaming and download platforms including Apple Music, Spotify and YouTube. This article on a United Kingdom television channel is a stub . You can help Misplaced Pages by expanding it . Television channel A television channel , or TV channel ,

1170-467: The VHF and UHF parts of the spectrum, are allocated for communication between fixed base stations and land mobile vehicle-mounted or portable transceivers. In the United States these services are informally known as business band radio. See also Professional mobile radio . Police radio and other public safety services such as fire departments and ambulances are generally found in the VHF and UHF parts of

1215-417: The absorption of microwave energy by the atmosphere. As frequency increases above 30 GHz (the beginning of the millimeter wave band), atmospheric gases absorb increasing amounts of power, so the power in a beam of radio waves decreases exponentially with distance from the transmitting antenna. At 30 GHz, useful communication is limited to about 1 km, but as frequency increases the range at which

1260-813: The air, called terrestrial television . 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. Some stations use LPTV broadcast translators to retransmit to further areas. Many television stations are now in the process of converting from analog terrestrial ( NTSC , PAL or SECAM ) broadcast, to digital terrestrial ( ATSC broadcast , DVB or ISDB ). Because some regions have had difficulty picking up terrestrial television signals (particularly in mountainous areas), alternative means of distribution such as direct-to-home satellite and cable television have been introduced. Television channels specifically built to run on cable or satellite blur

1305-502: The allocation still dedicated to television, TV-band devices use channels without local broadcasters. The Apex band in the United States was a pre-WWII allocation for VHF audio broadcasting; it was made obsolete after the introduction of FM broadcasting. Airband refers to VHF frequencies 108 to 137 MHz, used for navigation and voice communication with aircraft. Trans-oceanic aircraft also carry HF radio and satellite transceivers. The greatest incentive for development of radio

1350-443: The channel changed ownership from brothers Jaz and Davy Bal to a consortium with Tony Shergill as CEO. The new ownership significantly saved the channel's declining ratings by introducing a new vision for the channel and making the channel available to watch in North America (Canada & America), India, Africa and Australia with monthly viewing figures currently averaging 1 million viewers per month. In 2018 Brit Asia TV established

1395-599: The following table". The table originated with a recommendation of the fourth CCIR meeting, held in Bucharest in 1937, and was approved by the International Radio Conference held at Atlantic City, NJ in 1947. The idea to give each band a number, in which the number is the logarithm of the approximate geometric mean of the upper and lower band limits in Hz, originated with B. C. Fleming-Williams, who suggested it in

1440-446: The increasing size of transmitting antennas required. The size of antenna required to radiate radio power efficiently increases in proportion to wavelength or inversely with frequency. Below about 10 kHz (a wavelength of 30 km), elevated wire antennas kilometers in diameter are required, so very few radio systems use frequencies below this. A second limit is the decreasing bandwidth available at low frequencies, which limits

1485-452: The largest use of these bands has been by short-range low-power communications systems, since users do not have to hold a radio operator's license. Cordless telephones , wireless computer networks , Bluetooth devices, and garage door openers all use the ISM bands. ISM devices do not have regulatory protection against interference from other users of the band. Bands of frequencies, especially in

1530-460: The line between TV station and TV network. That fact led some early cable channels to call themselves superstations . Satellite and cable have created changes. Local programming TV stations in an area can sign-up or even be required to be carried on cable, but content providers like TLC cannot. They are not licensed to run broadcast equipment like a station, and they do not regularly provide content to licensed broadcasters either. Furthermore,

1575-677: The location and service provider Depending on the multinational bandplan for a given region, analog television channels are typically 6, 7, or 8 MHz in bandwidth , and therefore television channel frequencies vary as well. Channel numbering is also different. 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 . On satellites , each transponder normally carries one channel, however multiple small, independent channels can be on one transponder, with some loss of bandwidth due to

1620-532: The need for guard bands between unrelated transmissions . ISDB , used in Japan and Brazil , has a similar segmented mode. Preventing interference between terrestrial channels in the same area is accomplished by skipping at least one channel between two analog stations' frequency allocations . Where channel numbers are sequential, frequencies are not contiguous , such as channel 6 to 7 skip from VHF low to high band, and channel 13 to 14 jump to UHF . On cable TV, it

1665-406: The radio spectrum are a matter of convention in physics and are somewhat arbitrary. Since radio waves are the lowest frequency category of electromagnetic waves , there is no lower limit to the frequency of radio waves. Radio waves are defined by the ITU as: "electromagnetic waves of frequencies arbitrarily lower than 3000 GHz, propagated in space without artificial guide". At the high frequency end

1710-539: The radio spectrum are allocated by the ITU for different radio transmission technologies and applications; some 40 radiocommunication services are defined in the ITU's Radio Regulations (RR). In some cases, parts of the radio spectrum are sold or licensed to operators of private radio transmission services (for example, cellular telephone operators or broadcast television stations). Ranges of allocated frequencies are often referred to by their provisioned use (for example, cellular spectrum or television spectrum). Because it

1755-534: The radio spectrum is bounded by the infrared band. The boundary between radio waves and infrared waves is defined at different frequencies in different scientific fields. The terahertz band , from 300 gigahertz to 3 terahertz, can be considered either as microwaves or infrared. It is the highest band categorized as radio waves by the International Telecommunication Union . but spectroscopic scientists consider these frequencies part of

1800-595: The spectrum. Trunking systems are often used to make most efficient use of the limited number of frequencies available. The demand for mobile telephone service has led to large blocks of radio spectrum allocated to cellular frequencies . Reliable radio control uses bands dedicated to the purpose. Radio-controlled toys may use portions of unlicensed spectrum in the 27 MHz or 49 MHz bands, but more costly aircraft, boat, or land vehicle models use dedicated radio control frequencies near 72 MHz to avoid interference by unlicensed uses. The 21st century has seen

1845-464: The term has not been defined by the ITU. Broadcast frequencies: Designations for television and FM radio broadcast frequencies vary between countries, see Television channel frequencies and FM broadcast band . Since VHF and UHF frequencies are desirable for many uses in urban areas, in North America some parts of the former television broadcasting band have been reassigned to cellular phone and various land mobile communications systems. Even within

1890-468: The waves can be received decreases. In the terahertz band above 300 GHz, the radio waves are attenuated to zero within a few meters due to the absorption of electromagnetic radiation by the atmosphere (mainly due to ozone , water vapor and carbon dioxide ), which is so great that it is essentially opaque to electromagnetic emissions, until it becomes transparent again near the near-infrared and optical window frequency ranges. A radio band

1935-422: The world, usually emphasizing short-range communication between individuals or for small businesses, simplified license requirements or in some countries covered by a class license, and usually FM transceivers using around 1 watt or less. The ISM bands were initially reserved for non-communications uses of RF energy, such as microwave ovens , radio-frequency heating, and similar purposes. However, in recent years

1980-610: Was the first application of microwaves. There are several incompatible naming systems for microwave bands, and even within a given system the exact frequency range designated by a letter may vary somewhat between different application areas. One widely used standard is the IEEE radar bands established by the US Institute of Electrical and Electronics Engineers . The band name "tremendously low frequency" (TLF) has been used for frequencies from 1–3  Hz (wavelengths of 300,000–100,000 km), but

2025-478: Was the need to communicate with ships out of visual range of shore. From the very early days of radio, large oceangoing vessels carried powerful long-wave and medium-wave transmitters. High-frequency allocations are still designated for ships, although satellite systems have taken over some of the safety applications previously served by 500 kHz and other frequencies. 2182 kHz is a medium-wave frequency still used for marine emergency communication.
