End of analog TV in US

One "expert" was saying that he expects a bit of a shift away from cable and satellite services, with more people going back to antenna. Many people will see the number of available channels increase significantly - quadruple the number in some cases - with the addition of HD, all for free.

Now I'm confused; wouldn't it have made more sense to switch all of the digital frequencies to the VHF range when it got cleared up thanks to all the analog channels switching off?
The old analog frequencies will go to other services.

There is no reason for TV to use up spectrum. There are tons of other things that could use those same channels. Use groundwires for TV signals - this isnt the 1950s.

I'm sure that would provide a great picture!

From my new pseudo-understanding of digital TV reception this could apply in the urban areas where there's less blocking terrain

What are you talking about, my cable TV comes via a ground wire. The same wire can provide the free channels that use spectrum space.

Do you mean it is broadcast that way, or you can just get a signal that way?

Are you saying that your cable is on all grounds in your house?

My TV get's its FIOS signal via a cable under the ground. Not a Radio Signal, just an electric Signal.

So they are not just transmitting on a ground wire.

What? I have no idea what you're talking about.

There hasn't been a popular uprising demanding digital broadcaste television.

Connect the dots. The broadcasters pushed this legislation through to reacquire market share. They even obtained legislation to have the tax payers foot the bill for give-away digital-to-analog converter boxes.

There are lots of people that want to use the spectrum space being used by tv. It's a constant battle to get some bandwith.


The demand isn't from televison viewers.

Are you saying that the digital TV spectrum is narrower than the, now gone, analog spectrum?

A lot narrower I believe. Now they can squeeze in more channels for organizations who've been short on bandwidth in the past.

I haven't yet been able to come up with any solid numbers. Analog broadcast TV (NTSC) required, until today, 6 megherz per channel.

To keep up with cable and satellite services offering HDTV formats in MPEG-2 or MPEG-4 encoding 1280 x 720, at 60 FPS, they need to do the same. I'm still looking for a website willing to flip for the required broadcast transmission bandwidth.

Looks like there are both UHF and VHF digital stations; at least in my area. Check out what's in your area with this search: http://antennaweb.org/aw/welcome.aspx
