ARTICLES RELATED TO SÉCAM - SÉCAM varieties | | | |  SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - SÉCAM varietiesThere are three varieties of SÉCAM:
French SÉCAM (SÉCAM-L), used in France and its former colonies
SÉCAM-B/G, used in the Middle East, former East Germany and Greece
SÉCAM D/K, used in the Commonwealth of Independent States and Eastern Europe (this is simply SÉCAM used with the D and K monochrome TV transmission standards).
Reference is sometimes made to MESÉCAM as an alternative form of broadcast SÉCAM used in the Middle East. This is incorrect, MESÉCAM is meaningful ...

| | | | SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - Technical details Just as the other color standards adopted for broadcast usage over the world, SÉCAM is a compatible standard, which means that Monochrome television receivers predating its introduction are still able to show the programs, although only in black and white. Because of this compatibility requirement, color standards add a second signal to the basic monochrome signal, and this signal carries the color information, called chrominance or C in short, while the black and white information is called the luminance (Y in short). Old TV receivers only see the luminance, ...

| | | | SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - Problems with the standard Unlike PAL or NTSC, analog SÉCAM television cannot easily be edited in its native analog form. Because it uses frequency modulation, SÉCAM is not linear with respect to the input image (this is also what protects it against signal distortion), so electrically mixing two (synchronized) SÉCAM signals does not yield a valid SÉCAM signal, unlike with analog PAL or NTSC. For this reason, to mix two SÉCAM signals, they must be demodulated, the demodulated signals mixed, and are remodulated again. Hence, post-production is often done in PAL, o ...

| | | | SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - Why SÉCAM elsewhere? The adoption of SÉCAM in Eastern Europe has been attributed to Cold War political machinations: Western TV was popular in the East, authorities were well aware of this, and adopted SECAM rather than the PAL encoding used in West Germany. This did not hinder mutual reception in black&white, because the underlying TV standard B/G remained the same in both parts of Germany. However, East Germans responded by buying PAL decoders for their SECAM sets. Eventually, the government in East Berlin stopped paying attention to so-called "Republikfl ...

| | | | SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - History Work on SÉCAM began in 1956. The technology was ready by the end of the fifties, but this was too soon for a wide introduction. Initially, a version of SÉCAM for the then French 819-line television standard was devised and tested, but not introduced. Following a pan-European agreement to introduce colour TV only in 625 lines, France had to start the conversion by switching over to a 625-line television standard, which happened at the beginning of the 1960s with the ...

| | | | SÉCAM - SÉCAM varieties: Encyclopedia II - SÉCAM - Why SÉCAM in France? Some have argued that the primary motivation for the development of SÉCAM in France was to protect French television equipment manufacturers. However, incompatibility had started with the earlier decision to uniquely adopt positive video modulation for French broadcast signals. In addition, SÉCAM development predates PAL. NTSC was considered undesirable in Europe because of its tint problem requiring an ...
