In fact, you could use a converter box and a very small "handheld" TV propped up on top. And what about low power licenses for that very purpose? |
WJCT does the same thing on 7.5. They show community calendar events and play their sister station's sound WJCT-FM
Trip would know the rules surrounding transmitting audio without video, but if a simple card is up it doesn't take much bandwidth.
One could put up a card and music with about 1.5 mbps, which could fit 12 of those in a video channel. Most of the bandwidth would be video.
If you didn't need to add video (not sure how the rules deal with this), it only takes about .20 to .40 mbps. This leaves room for a LOT of audio programs. At .2 you would but up to 90 stations on one TV carrier.
You could put about 45 5.1 Dolby audio programs on a TV channel if nothing else were there.
If you wanted to compare it to FM radio, 3.3 channel would be the same size as the FM band we have now.
It was hoped by a few, very very few that mattered that maybe CH6 could have been used to expand the FM radio band, adding about 30% more room. It would have been nice. But as it turned out of all the lowband channels occupied with
DTV, CH6 is one of the most popular.
