How can a signal control what should be displayed on the screen?How does a signal arrive to a TV set and control which pixels should be illuminated?
It arrives as information encoded on an electromagnetic wave my modulating the signal. That's the radio technology. The TV uses that information to 'decide' the illumination at each point. Start at the reference, but look at a basic radio/electronics book at a library.How does a signal arrive to a TV set and control which pixels should be illuminated?

the color pixel is control by the color burst on the leading edge of the pedestal
