Since four channels (or even more; WBPX-68 here in Boston has a main channel and five other digital sub-channels) can be squeezed-into a single digital TV signal, I would think that the CW affiliate and the Buzzr “diginet” (the latter carries classic game shows) can all easily fit into WHDH-7’s signal.
Given that, could what is now WLVI-56 still be “mapped” as Channel 56.1 and Buzzr “mapped” as Channel 56.2 for over-the-air viewers??
I would think that this would be the end of the WLVI call letters being used by a Boston TV station. Look for either a TV station broadcasting on “mapped” Channel 56 in another city or a radio station broadcasting on 560 kilohertz to quickly snap-up the WLVI calls.
And if the Globe article is correct (as regards how much WLVI’s “spectrum” is worth), WHDH/WLVI owner Ed Ansin may make at least twice as much money selling WLVI for spectrum use than what he had been offered by NBC in late 2015 for WHDH.
