Tutorial needed on TV decoder design
 
I am looking for a tutorial or book or website (checked google, does not seem to come up with anything useful) that covers building a TV decoder. Basially I want to take in the composite TV/Audio signal, separate the components and the sync pulses and then output an X/Y waveform (to control the horizontal and vertical alignment on an oscilloscope or TV) and a brightness component to control the actual picture, the signals I will be decoding are black and white so colour TV control is not needed (though it would be cool).

Any ideas on where to look or any suggestions?

So basically you want a TV or at least part of it.

Yeah, wanna look over it and build one, doing it as a project at uni however I want to make a better one than just the simple ones I could build right now, I suppose I am really looking for good circuit designs for small signal amplifiers... was hoping that a commercial quality Tv would have some of these type of things in them so I could get an idea of what I am looking for.

look at an IC data book. you should find example circuits.

you want a sync separator, etc.
the video is usually called the "z" componant.

A TV block diagram may make things clearer.
