The reason I ask, I have yet to read anything positive anywhere on the 'net about the DTV converter boxes that are/were on the market.
The DTV transition starts next Aug' in Canada. So it'll be interesting to see how that goes.
Gosh where to start.
I guess "magic" won't work here.
I will limit this to "over the air" tuners and leave cable out of it.
There are primarily two types of over the air tuners in the US (Does Canada use PAL? - No idea but that would be three)
There is the NTSC tuner type (National Television Systems Committee) that is the previous standard by which Analog TV signals were broadcast. All "old" TVs and some newer "Digital Ready" TVs have NTSC tuners. They receive the 3-13 and UHF channels BUT not the new digital channels.
These TVs use the same outdoor antenna (as long as they receive UHF) as digital. There is NO difference between the old and new sets as far as the antennas go. As I posted earlier, the Frequencies of the broadcast did not change, just how the information was packaged and sent over that frequency.
In order to receive digital television signals on these older sets and "digital ready" sets, you must convert the new standard to the old NTSC one. More on these in a bit.
The NEW standard is called ATSC. (Advanced Television Systems Committee. The Digital Standard. ALL TVs made today have ATSC tuners in them (plus a cable one but that's another issue - remember "cable ready" blah blah) and can receive broadcast digital high definition (up to their maximum capability - there is more than one high def standard) from any
over the air antenna that will receive VHF and UHF signals.
So, if your camper has a new set (almost all flat screens) with an ATSC tuner, your just crank up your 1983 Winegard antenna; turn on the TV; do a scan and channel 17.3 comes in clear as a bell.
BUT if you have a 1983 TV in there you have a problem. IT has a NTSC tuner. It does NOT receive ATSC signals. You just get SNOW.
So, what is a mother to do? You buy an ATSC to NTSC converter box for 50 bucks.
This becomes your new tuner. You set your old TV to your aux input, (the red yellow white phono plugs that your Atari plugged into) OR you set the TV to channel 3 or 4 and use the RF output of the converter box.
You get a brand new remote since you will be changing channels on the converter box from now on. The RV antenna now hooks up to the converter box, and it happily swallows that meaningless snow and turns it into TV channels again. Hello, channel 17.3 on the converter box.

So, long story longer, your friends from Myrtle Beach most likely had a new TV that has the new digital tuner in it. They literally did not have to do anything but turn it on; do a scan; and watch TV.
If they had an older set, they would need a box to get the new channels.
