US Still Dithering Over Analog-Digital TV Conversion

Robin Ingenthron writes "As 2007 gets closer, the legislation to postpone mandatory transition from Analog TV broadcast to Digital is taking shape. Here's an idea - make the broadcasters pay to use the airwaves (they get both analog and digital spectrum for free). For that matter, why permanently auction the bandwidth to cell phone companies, why not rent it to them too? Each postponement keeps the Fed budget in the red, so consumers have a choice -- between analog (black borders on the sides of their digital TVs) and digital (black borders on the top and bottom of their analog TV)."

    McCain's measure would require broadcasters to air only digital television signals by 2009 and help consumers who rely on traditional television sets buy devices that would convert digital back into a format that they could watch.

    "Consumers who rely on over-the-air television, particularly those of limited economic means, should be assisted," according to the draft obtained by Reuters.


    How about we just not mandate that the signals go all digital? I have said it before... The taxpayers are getting fucked TWICE on this deal. We have to pay for the mandate to happen and we have to pay for the fucking digital tuners as well all for something that I really don't care to have anyway. TV isn't that important as it is, especially stuff that comes OTA so why do we need to waste billions of dollars on this technology? Just so I can watch the Vikings lose or the Simpsons have another bad season in digital quality? No thanks... How about you spend that money on regulating the corporations that deliver content over cable and telephone? Personally I am more interested in that digital information.

    And because I don't want a digital set/tuner I won't be able to watch TV without it. I am assuming I wouldn't be one of those people that are considered acceptable for help...

      There are two reasons for the switch:

      1. The new technology makes more efficient use of the bandwidth

      2. The bandwidth currently being used by TV signals is particularly valuable set of frequencies. One important potential use of it is for emergency communications, which couldn't be done as well at the higher frequencies to which the TV networks are being moved. (I believe that has to do with the better penetration capability of the lower frequencies, while the relatively immobile TV receiver can use an exertnal antenna. But I'm not certain of this.)

      A corollary to #1 and #2 is that the bandwidth can be resold to wireless providers for a lot of money, thus netting a windfall for the US budget and decreasing the deficit.

      Oh, BTW: you probably won't actually get the Simpsons in higher quality. The DTV standard allows them to subdivide the signals, so they get to pump you the Vikings losing AND the Redskins losing AND the Red Sox losing at the same quality as you already had.

      The upshot: it's not about quality; it's about efficient allocation of bandwidth and the ability of the US consumer to have more options and make some money off the sale of bandwidth. (Not enough, to my tastes: the TV networks make vast sums of money off that bandwidth, because an awful lot of people enjoy what they're producing.)

      That may not be sufficient reason for you to outweigh the price of the digital tuners, but there are reasons.

      I see that you're an optimist. In my experience digital TV pictures are actually worse quality than traditional broadcast TV. Because the entire image is MPEG-2 encoded, even a tiny bit of interference can cause the screen to freeze or display brightly coloured artifacts. Because the signal is being squeezed into the absolute minimum possible bandwidth the overall quality comes out as being slightly below what I would expect from a bootleg VCD.

      The worst part of digital TV isn't even the picture quality, it's channel surfing. With the current technology you just can't do it. If you try to page through traditional broadcast or cable channels it's easy -- *click* *click* *click* and you see three different channels. With digital TV there is a delay of at least a second after selecting a new channel while the decoder pores over the data stream trying to piece together an image. *click* *click* *click* turns into *click* ... ... ... *click* ... ... ... *click* ... *swear*

      While it would be technically possible to overcome these problems by upping the bandwidth allocated to each individual station, the money to be made by packing as many extra channels as possible into the available spectrum will always be too much to ignore. If you expect the same quality as you get today from digital TV, you're going to be disappointed.

      My experience is quite different. You first have to realize that not all digital is the same. For instance, the digital from my local cable company is overly compressed. I switched from Dish Network, to cable, back to Dish (1 month later). The picture quality for the cable was pretty bad - the first 100 analog chaneels were very fuzzy. The digital channels were better but not as good as I got off my satellite (near DVD quality). Others in my family have DirecTV which appears to me to not be as clean of a picture (less resolution from compression). Different people will get different results from their local cable co.

      The picture quality and sound I get from the HDTV satellite feeds (Dish Network) are excellent. My HDTV tuner can also tune in the digital and analog over the air signals. HDTV OTA signals are the best of all since they are the least compressed and have the highest resolution, way better than DVD.

      Be careful when comparing analog to digital. Digital has the capability to be better than analog in both picture quality and sound. The market will decide if we want more channels or fewer higher quality ones.

      That is not a tiny ammount of interference. DTV uses almost 50% of its bandwidth for Forward Error Correction (FEC). It takes a lot to take the signal off the air unless you are near the boundaries or reception, which with analog would get you a pretty poor picture anyway. As for the artifacts? That has to do with the encoder, not the signal. Don't even compare this to VCD, I work around these pictures every day and can see how much higher quality they are than regular TVs.

      The delay? They new that would happen from the begining. If you know about Iframes, remember that they have to wait till they recieve one till they can actually start showing a picture. A half second delay at most under the current way of broadcasting. And yes, I do mean a half second AT MOST, unless you have a poor quality decoder.

      Upping the bandwidth would not change this. Changing the LongGOP of the MPEG structure would, but that would require more bandwidth to keep the same quality. As for quality? They can set it from 19.4Mbps to 0Mbps for the ammount of bandwidth they use for a signal. 19.4 is way above DVD quality so don't diss it. What was probably happening is that they were reducing the ammount of bandwidth dedicated to the subchannel you were watching to another channel. Most stations will only use 4 sub channels at most under the current scheme of things. 4 channels being the most number of Standard Deffinition [720x480I] that you can fit into 19.4Mbps under most circumstances and maintain quality.

If it was a state by state thing it would end up costing taxpayers more in the end and may result in those living at state borders not having any reasonable broadcast TV as two states are in a pissing contest as to who gets to host the transmitter (and thus get the tax revenue). By licencing on a federal level those issues are rendered non-issues.
