SECAM is an analog color television system first used in France. A team led by Henri de France working at Compagnie Fran
A multi system plasma TV is a TV that has a plasma screen. It is also able to pick up signals from various broadcasting systems. Other countries use PAL and SECAM, while America uses NSTC. For this reason, multi system TVs are compatible for use in many areas of the world.
Digital Video Broadcasting, or DVB is an accepted format for television broadcasting signals. There is a worldwide consortium that has patented the technology behind the various accepted television signals. This is so that all digital signals can be the same for all countries, as opposed to the analogue method of NTSC, Secam, and PAL.
SECAM is short for Sequential Color with Memory, SECAM is a color TV standard that was introduced in the early 1960 in France. SECAM uses the same resolution as PAL but transmits the color information sequentially
PAL (PHASE ALTERNATING LINE) is Colour Encoding Method for Broadcasting Video Signals. Other Methods are NTSC & SECAM.
Analog.The US & Canada used a system called NTSC.The UK & most of Europe used a system called PAL.France & the USSR used a system called SECAM.
In the past TVs were separately made for PAL/Secam/NTSC programs. Now almost all new TVS are with multiple function. So if you have a muti-system TV, it will work in Bulgaria
For terrestrial analogue systems (while they still exist) the UK, like most of the rest of Europe, uses a system for encoding the colour called PAL (phase alternating line). The French, however, use a system called Secam (Sequence and memory). To a television receiver, the two systems are mutually incompatible, so unless you have a television that can switch between the types of signal, you will only be able to receive one or the other.
There are several milestones in the introduction of color television. The first demonstration of color television was carried out by John Logie Baird in 1928. He was also the first to demonstrate monochrome television in 1925 and using the same system of rotating discs for color television. The BBC were about to adopt his system for public broadcasting but used the monochrome version rather than color. After Philo Farnsworth had successfully shown a fully electronic system in 1929, Baird put forward a proposal for an electronic color encoding system and this was published in 1939. His proposal was used as the basis for future color broadcasts. In 1942, the US saw the first public color broadcast. The system was not compatible with the existing monochrome one and it was terminated only a few months later. 1954 saw the introduction of RCA's color system in the US. It was fully compatible with the monochrome broadcasts and this system has remained in use until today. Britain was later to develop a color encoding system. Similar to the US NTSC system, the British PAL encoding avoided some minor issues of NTSC. It was first broadcast in 1967. Other countries introduced one of the two systems in the years that followed although France chose a third system known as SECAM.
PAL is the color encoding method used in Europe and other parts of the world. North America, Japan and other countries use NTSC. Although the two encoding methods are similar, the signals are not compatible. A third color standard used by France is SECAM. SECAM is used in a handful of other countries but is not a common standard. PAL and SECAM encoded signals are normally used at 50Hz while NTSC normally uses 59.94Hz. There are some rare exceptions to these field rates but it is normally safe to assume that 50Hz material will be PAL encoded and 59.94Hz will be NTSC encoded.
PAL is the color encoding system developed by the British and Germans. It differed from the American NTSC encoding system in several ways and the two are not directly compatible. Because of the British links to the rest of the world, most British colonies (currently or previously) use PAL. This now extends to most of Europe, Africa, Australia and New Zealand. The Americas and the far East tend to be NTSC regions but for a full list, there are many web sites that show every country and the formats they use. France chose a different format when it began color broadcasts, known as SECAM. Although SECAM is still used for the final broadcast, all television production uses PAL format for ease of signal processing. The content is converted to SECAM for distribution to viewers. Several of the French colonies still use SECAM although the format is becoming less popular. With the advent of high definition television, PAL, NTSC and SECAM are no longer used. Each of them are color encoding systems for standard definition signals only and encoding for HD does not use them. However, HD is still often incorrectly referred to as PAL or NTSC. Partly, this is due to the fact that NTSC uses a 60Hz frame rate while PAL uses a 50Hz frame rate. The move to HD has retained the differing frame rates. HD PAL therefore is more properly known as 50Hz HD.
The TV system for the US is different to that of the UK, which is different to France and so on. Some use the same system but not always. I won't go into technical details, but the differences affect the colour and sound content of the video signal. The US television system uses a system called NTSC where as the PAL system is used over here in the UK. (In France they use SECAM). Basically, look for a UK video recorder that supports NTSC playback (you can get more expensive VCR's that will record in NTSC too!). That's it. The picture quality should be okay, but may be a little poor compared to the UK PAL playback.
