Pretty much dead on.
1 television channel is 6 mhz. (assuming non HD).
With reasonable compression (and probably even more now if they moved to mpeg4/h.264 instead of mpeg2 when I last worked with the stuff) is that you
can squeeze about 4 analog channels into one 6 mhz space if you convert it to digital.
