SECAM uses frequency modulation and outputs either R-Y or B-Y on 
alternate lines, so the colour resolution is less and you need to buffer 
it. It is after all "Sequential colour with memory"

It's great for adding colour to black and white broadcast as it's 
resilient and you get no dot crawl.

For locally generated content it's a pain, which RGB SCART solved. Which 
is you live in europe is something you should be thankful to SECAM for.
