Strange! My Sanyo 26" LCD HDTV from 2006 always showed "WTIC 61-1" on antenna (when I had one hooked up anyways). My mother's TV on cable, with no converter (and my TV now, also with no converter), shows them as "WTIC 61-1" and Antenna TV as "WTIC 61-2". If this is the case Scott, what actually goes out on WTIC 61-1?
If the question is, "what's on RF channel 61?," the answer is nothing, at least no TV broadcasts: the digital TV spectrum ends at the old channel 51 and by year's end even the remaining LPTVs on 52-69 will have been cleared away as those frequencies transition to other uses.
But, again, *any* channel number is a virtual concept. As W9WI is so fond of pointing out, all TVs from the beginning have used channel mapping. It's just that it used to be a fixed mechanical mapping - any analog TV, anywhere in America, that was tuned to "channel 2" was receiving a signal between 54-60 MHz. Today, that same TV could be tuned to "channel 2" and could be receiving an over-the-air ATSC digital signal anywhere between 54 and 700 MHz, or could be receiving an analog cable signal on 54-60 MHz, or a digital cable signal anywhere from baseband to 1 GHz, or a digital satellite signal somewhere up around 12 GHz.
You don't need to know that to watch "channel 2," any more than you need to know that the server running this message board is at IP address 72.29.72.50 in order to get to boards.radio-info.com. If you're within range of New York City TV, whatever underlying reception technology you're using, you select "2" (or "2.1") and you get CBS, channel 2. End of story.
And in that sense, you could say that what's "actually" on 61.1 is...WTIC-TV.
Meanwhile, I guess they'll never change the digital assignments for this market or Boston/Worcester, considering both use channels 20, 31 and 39 for digital (WTXX, WTIC and WCTX here along with WCVB, WFXT and WSBK there).
It's a better bet that some digital assignments
will shift in the next few years, especially if the FCC follows through on its plan to repack the spectrum to free up more bandwidth for wireless broadband. The beauty of virtual channels is that as a viewer, it won't matter to you - you punch in "20" to get WTXX and "61" to get WTIC now, and wherever those underlying RF channels go, you'll still get WTXX on "20" and WTIC on "61," just the same way that you'll always find this site at "boards.radio-info.com" no matter what server and underlying IP address it happens to be using.
