Essentially correct, but I thought the discussions specified "NTSC 
encoder/decoder" and "MPEG encoder/decoder".

I think most of us understand the difference, but I can see where it could get 

NTSC encoders and decoders are things that most of us here don't get 
involved with.

The reference to an NTSC encoder was actually referring to an NTSC tuner, 
demodulator and decoder, meaning something that could turn an NTSC RF 
signal into usable video.

But please, continue to keep us all honest :-)
