Television signals general questions

[elegysix]

Do lcd televisions / monitors process component signals for each pixel in every frame? or is there like an approximation it uses? how complex is the signal with this information?

I mean like, if I were to take the video cable out of my TV, and hook it up to an oscilloscope, what sort of frequency would I see? How many Mbps or Kbps does cable tv need to produce a full video in real time? (not analog tv)

I guess I'm asking how is information sent from my cable provider to my tv, and how much information is sent per second?

thanks
