FCC Says Analog TV Lives Until 2012
walterbays writes ""The FCC voted 5-0 to require that cable operators must continue to make all local broadcasts available to their users, even those with analog televisions." I don't understand how AT&T manages to deliver U-verse without any analog channels. Did they get it classified as not-cable and exempt from existing rules? Or as a result of this vote, will they suddenly have to drop 50 SD channels to make room for 5 NTSC channels?"
everywhere you used HD in your post.. switch it to digital. digital!=HD
You don't know what the hell you're talking about.
The "US is behind in mobile phones" argument is bullshit. You might argue that the contract model we use is broken, and it probably is (although it does result in surprisingly good deals for many subscribers). But we have the same technologies as the rest of the world (GSM/UMTS/HSDPA), in addition to CDMA2000 (which is also used by South Korea, Canada, and some other countries) and iDEN. We have two healthy national GSM carriers (and soon two national GSM/UMTS carriers). I can buy any of the fancy GSM/UMTS phones out there and use it on a US network (assuming that it's unlocked and has the right bands).
Maybe you think we should have enforced a GSM monoculture like the EU. But that's not the way we do things in the US, and our way seems to be working out fine.
And I can't believe how terrible the sound quality is on GSM networks compared to CDMA networks.
GSM EFR (or the equivalent AMR-FR) sounds better than CDMA. Unfortunately, AT&T is running half-rate AMR (AMR-HR) on most of its network to increase capacity. AMR-HR is passable, but it's definitely not as good as EFR or AMR-FR.
FYI, the CDMA vocoder has a lot of noise cancellation, which is one reason it works with lower data rates.
Not only that, but digital cable REQUIRES a set top box because they encrypt the BASIC CABLE channels? So, even if I go out and spend $4000 on a giant wall mount Digital LCD panel, I still have to have the SET TOP BOX unless I want to limit myself to OTA (Over The Air Broadcast) HD channels and Digital Mexican Music stations. I want the FCC to mandate that DIGITAL CABLE has to work the same as ANALOG CABLE so I don't need a SET TOP box for NON-PREMIUM CHANNELS.
NTSC and ATSC use the same amount of bandwidth (6 MHz). The spectrum savings are from the ability to pack the stations more tightly, in space and frequency, in the broadcast band. ATSC is more resistant to interference, so less spectrum is wasted on guard bands and geographic separation.
