No, although that makes for a great myth. NTSC video has 490 lines of visible picture per frame. There are 30 frames per second (humor me). 490*30=14,700 lines/second. CD quality audio is sampled at 44,100Hz. 44,100/14.700=3. The devices used to encode digital audio to U-Matic recorders encode three (3) 16 bit samples per line.
ok, we are officially side tracking this thread.

i had read that NTSC video had maximum vertical resolution of 480 lines. it is 490?

so it it isn't 480*29.97=14385.6? 44100/14385.6=3.065...
