Television signals general questions

  1. Jun 6, 2012 #1
    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?

    This intro article at wikipedia has lots of good links out to other sources of the info that you are asking about (like digital TV, etc.):
