List Of BBC Test Cards
The following is a list of test cards used by the BBC at various points in broadcasting. Tuning Signals The first " Tuning Signals" test card was broadcast by the BBC in 1934. It was a simple line and circle broadcast using Baird's 30-line system, and was used to synchronise the mechanical scanning system. Test Card A Test Card A made its debut in 1937. However, it and Test Card B were soon replaced by the more useful Test Card C. Test Card B Test Card B was an early BBC television test card. It was very similar to Test Card A but was never broadcast, possibly used by BBC engineers for internal use. The original card has since gone missing. The only difference was it had an extra greyscale stripe below the circle. The letter box in Test Card A was moved to the top of the card. Test Card C Test Card C was a BBC television test card first broadcast in 1948. It was the first test card to resemble the famous Test Card F. It was also available as individual rolls of test fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Test Card
A test card, also known as a test pattern or start-up/closedown test, is a television test signal, typically broadcast at times when the transmitter is active but no program is being broadcast (often at sign-on and sign-off). Used since the earliest TV broadcasts, test cards were originally physical cards at which a television camera was pointed, allowing for simple adjustments of picture quality. Such cards are still often used for calibration, alignment, and matching of cameras and camcorders. From the 1950s, test card images were built into monoscope tubes which freed up the use of TV cameras which would otherwise have to be rotated to continuously broadcast physical test cards during downtime hours. Electronically generated test patterns, used for calibrating or troubleshooting the downstream signal path, were introduced in the late-1960s. These are generated by test signal generators, which do not depend on the correct configuration (and presence) of a camera, and can als ...

BBC Two
BBC Two is a British free-to-air public broadcast television network owned and operated by the BBC. It covers a wide range of subject matter, with a remit "to broadcast programmes of depth and substance" in contrast to the more mainstream and popular BBC One. Like the BBC's other domestic TV and radio channels, it is funded by the television licence, and is therefore free of commercial advertising. It is a comparatively well-funded public-service network, regularly attaining a much higher audience share than most public-service networks worldwide. Originally styled BBC2, it was the third British television station to be launched (starting on 21 April 1964), and from 1 July 1967, Europe's first television channel to broadcast regularly in colour. It was envisaged as a home for less mainstream and more ambitious programming, and while this tendency has continued to date, most special-interest programmes of a kind previously broadcast on BBC Two, for example the BBC Proms, ...

Telefunken FuBK
The Telefunken FuBK (from the German ''Funkbetriebskommission'' for "''Television Service Commission"'') is an electronic analogue television test card developed by AEG-Telefunken and Bosch Fernseh in West Germany as the successor to the monochrome T05 test card in the late-1960s and used with analogue 625-lines PAL broadcasts. Not as popular as the Philips PM5544, nevertheless it saw widespread use in West Germany (and later reunified Germany) and some other European, Asian, South American and African countries, and by a few commercial TV stations in Australia. The test card was generated electronically by several video-signal generators, including two variations of the Philips PM5644 generator (PM5644G/50 and PM5644G/70 ) and the Rohde & Schwarz SGPF-B3 (the Grundig VG 1001 test signal generator has a different pattern design, but is sometimes indicated as "FuBk" because it features similar test elements). It has also been used in conjunction with digital broadcasts by m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It occupies an area of and has a population of about 287,000 (2019 estimate). Its capital and largest city is Bridgetown. Inhabited by Kalinago people since the 13th century, and prior to that by other Amerindians, Spanish navigators took possession of Barbados in the late 15th century, claiming it for the Crown of Castile. It first appeared on a Spanish map in 1511. The Portuguese Empire claimed the island between 1532 and 1536, but abandoned it in 1620 with their only remnants being an introduction of wild boars for a good supply of meat whenever the island was visited. An English ship, the ''Olive Blossom'', arrived in Barbados on 14 May 1625; its men took possession of the island in the name of King James I.

After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led ...
