Can you please suggest  a site, where I can find the specifications
for the comb filter etc for NTSC decoding. From the books that I have,
it is not very clear ...

Here is the plan that I have thought 

Samples --> Comb Filter --> Extract Y and Timing Info --> Display

Once the monochrome reception works properly I will go for color ..

Any comments ??
