What frequency range are video & music signals in?

Question by MTRstudent: What frequency range are video & music signals in?
Specifically that output by a VHS player.

If I were to send a periodic signal to get a blank screen (eg red, blue, green, whatever), and then use fourier decomposition to find the component frequencies, what range of frequencies would I find, and what sort of distribution of frequencies would there be?

A reference for me to read would also be appreciated!

The audio is in the … audio .. range, that is, 20Hz to 20kHz

An ordinary composite signal is in the range of 0 to 4 MHz. See the reference for more detail.
