BBC South East
BBC South East is the BBC English region serving Kent, East Sussex (including the City of Brighton and Hove), parts of West Sussex and Surrey. The BBC region was created in September 2001 by the joining of the Heathfield transmitter (formerly part of the BBC South region) with the Bluebell Hill and Dover transmitters (from the then BBC London and South East region) to form a new regional TV service. Unlike ITV Meridian (East), it does not provide local news for southern Essex (received from a Bluebell Hill overlap), this area being part of the BBC London region instead. Services Television BBC South East's television output consists of the flagship regional news service '' South East Today'' and its main programme is broadcast weeknights at 6:30 pm, with short bulletins throughout the day and during the weekend. A half-hour opt-out during '' Sunday Politics'' is produced by an independent production company. In 2020, ''South East Today'' joined forces with '' BBC Londo ...

ITV1
ITV1 (formerly known as ITV) is a British free-to-air Public service broadcasting in the United Kingdom, public broadcast television channel owned and operated by the British media company ITV plc. It provides the ITV (TV network), Channel 3 public broadcast service across all of the United Kingdom except for the central and northern areas of Scotland where STV (TV channel), STV provides the service. ITV1 as a consistent national channel (with dedicated slots for regional news and other regional programmes) evolved out of the old ITV (TV network), ITV network – a federation of separately owned regional companies which had significantly different local schedules and branding. During the 1990s, the differences between the schedules in each region gradually reduced – partly through the consolidation of ownership and partly through the standardisation in the volume and scheduling of regional programmes. In 2002, a major change of appearance occurred when all ITV regions in En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monaural
Monaural sound or monophonic sound (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical audio signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimetre). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF ( very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowridge Transmitting Station
The Rowridge transmitting station is a facility for FM radio and television transmission at Rowridge on the Isle of Wight in southern England. It currently has a tall guyed mast, owned and operated by Arqiva (previously National Grid Wireless). There is a smaller tower on the site belonging to British Telecom. Prior to Digital Switchover (DSO) the station broadcast with a power of 250 kW ( ERP) for FM radio, 500 kW for analogue television, and 20 kW for digital television. In July 2007, Ofcom confirmed that Rowridge would remain an A Group transmitter at Digital switchover; the digital television transmission signal was then boosted to 200 kW. From March 2018 MUXES 7 & 8 moved out of the A group to channels 55 & 56 (segraph, though these are due to be turned off between 2020 and 2022. Rowridge is one of only two main transmitters (the other is the rather smaller transmitter of Rosneath in Scotland) to broadcast its output on both horizontal and vert ...

Crystal Palace Transmitting Station
The Crystal Palace transmitting station, officially known as Arqiva Crystal Palace, is a broadcasting and telecommunications site in the Crystal Palace, London, Crystal Palace area of the London Borough of Bromley, England (). It is located on the site of the former television station and transmitter operated by John Logie Baird from 1933.

As such, it is the most important transmitter in the UK in terms of population covered. The transmitter is owned and operated by Arqiva. Given the transmitter's location on top of a hill, it is the highest structure above sea level in London. History and development The station was constructed in the mid-1950s among the ruins of the Crystal Palace. The Aquarium on whose site it stands was destroyed in 1941 durin ...

South Downs
The South Downs are a range of chalk hills in the south-eastern coastal counties of England that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs, and includes large parts of the Weald. The national park is the UK's most visited, attracting an estimated 39 million visitor-days annually. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to ...

Broadcast Relay Station
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater ( two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. These expand the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. Depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Translators In its simplest form, a broadcast tra ...
