WHYY has announced they're going to install it, but have not yet actually done so. That's what the little orange-ish icon means.
WTVE 51 (25) 5.5 Mbps
No wonder this station doesn't have any subchannels. They are wasting an unusually large number of bits on their Mobile program. Most of the low-definition 240p stuff I grab off the net only uses 0.1-0.3 Mbit/s. Using 5.5 is overkill.
You have to bear in mind, as bdfox18doe mentioned, that you have to error-correct these things a lot more than a fixed Internet connection. From what I understand, and I could be wrong, it takes 1.83 Mbps of data on the main ATSC side to produce a ~0.3 Mbps video stream on the ATSC-MH side, due to the huge amount of error correction needed.
Now since I also do not yet have a receiver, I don't know if WTVE is doing one MH stream or three. If they're doing three, then the usage of 5.5 Mbps seems perfectly fine to me. Even with that much bandwidth dedicated, they still have 7.4 Mbps of unused bandwidth.
