HI all
I am very confused as to why they are going to side bands.. and not staying on there orginal chanels. seams like a scam to me.. Below is the question I asked of our tv station here and there answer.. We watch it on Channel 7 .
********************************************************
My Question..

If they are going Digital why are they changing Frequency??? If they are going to digital they can run ANY combination of channels. Why are they going to 7.1 or 7.2 instead of staying on 7?? There is no reason they have to go to a side number like the .1 or .2 ... other than making it so people HAVE to have a digital TV or a converter box.... Sounds to me like a Scam to make everyone and the Poor person have to buy a new TV or a Converter box.. or lose there TV signel.... unless you can prove me wrong.... and I don't think you can....

Answer first question

When the FCC mandated that the full service TV stations start broadcasting in digital they “gave” each full power station an additional channel to start broadcasting digital TV on. KTVB’s digital RF channel is CH 26. The reason for having 7.1 & 7.2 is that a digital TV station can operate with up to 4-5 channels on a given carrier and the home viewer doesn’t need to really know what RF channel they are actually on. That is taken care of by something called PSIP (Program & System Information Protocol). AS an example Idaho Public TV goes from 4.1 to 4.5. The analog channels for KTVB is considered 7.0, primary digital channel 7.1, secondary digital channel 7.2. Also this channel mapping is actually a requirement of the FCC using the PSIP. With the digital system we can actually put more data into the same channel bandwidth that the analog signal currently occupies and that is why we have more then one digital channel for each TV station.

you just get tired of fixing it.

Old analog TV and new Digital TV signals are like comparing apples to spark plugs, it's totally 100% different. The digital channels need to be able to co-exist with analog channels during the transitional phase, which is one of the reasons they operate at totally different frequencies.

Secondly, if one day they started broadcasting digital channel 7 on the same frequency as analog channel 7 was on yesterday, your analog TV set would just show snowy garbage. It doesn't understand digital, it's a completely different way of representing information. Expecting an old analog TV to receive a 'lower quality' version of the digital TV signal is like expecting your dog to watch digital ones and zeros fly by on your computer screen, and expect him to know it was the Cooks Garage web site. It's a completely different 'language', if you will.

Lastly, the reason the old analog TV frequencies/channels have to 'go away' at some point in time is because the FCC wants to reclaim those frequency bands, so they can be used for other purposes. There are only so many frequencies that can exist on the airwaves, and with so much wireless communication going on, it's getting pretty full. They need to reclaim this 50+ year old stuff so that it can be put to better use. And all that means is that you can't pick up analog channels using your bunny-ear antennas... the cable and dish companies will be supporting the old analog TVs long after the analog channels are wiped from the airwaves.

Thanks Ian
I think I understand now.. LOL...
Let me get a hammer and put a few more dents in my head... LOL..

Big Brother is going to give out vouchers for a digital converter that hooks to analog TVs so you can use your analog TV as long as you like.

yea but it only cuts the price in half I think so you still have to pay $50.oo or so.

You can get a limit of two per house.

"When TV converter boxes are available, retail stores will set the price. TV converter boxes are expected to cost between $50 and $70. The Federal Government permits each U.S. household up to two $40 coupons to help pay for the cost of the converter box. After applying the coupon, participating retailers will charge consumers the remaining balance of between $10 and $30."
