Hi all,
Can anyone tell me what "SECAM" means? Also I understand PAL and NTSC, but on this card is also "PAL BG", "PAL DK", "PAL I", the same with SECAM plus "SECAM LL".
TIA!

SECAM is the term used to describe the French alternative to NTSC and PAL. NTSC and PAL encode the colour information by means of phase modulation of a colour sub-carrier. SECAM uses FM instead. I think they are compatible if you only want black and white. They also degrade at different rates when the radio signal is poor. There are slightly different national versions. A modified version of SECAM is also used in Russia. Regards. -- Geoff Bagley
