HD 101: What is ATSC, PSIP, QAM, and 8-VSB?

SDV posts



We knew that Time Warner Cable was allowing customers in various regions around the country to pre-order their tuning adapter, and tonight we've received the first report of delivery. For those out of the loop, these free adapters enable CableCARD users to tune into any channel that's delivered via switched digital video (SDV); without one, your current TiVo (for example) won't ever be able to see any channel beamed out with the new technology. The lucky locale is Austin, Texas, but we get the idea that other places should be seeing them soon. Give your local TWC office a call, and do report back (bonus points for images) if you've found that your city now has 'em as well. [Disclosure: Engadget is part of the Time Warner family]
You already know what Comcast's Digital Transport Adapter looks like, and for folks in Salem, Eugene and Corvallis, Oregon (not to mention Seattle, Washington), you'll be seeing 'em in the flesh soon enough. Comcast has announced that its all digital transition will be heading up from Portland and into Seattle in the near future, and it's upsetting quite a few locals with Media Center PC / TiVo setups. Of course, these are just the growing (or should we say "changing") pains associated with a mass switch from analog to digital, but at least in theory, the conversion should free up oodles of bandwidth for the carrier to expand its HD lineup. And remember, a cable company choosing to pipe its channels out in digital is very different than the broadcast change coming in February 2009 -- it's confusing, we know, but the read link does a fairly decent job of spelling everything out.
If you've been feeling left out because your cable provider decided to start using Switched Digital Video (SDV) to deliver your favorite channels, don't worry because the FCC has your back. Today the FCC's Enforcement Bureau proposed to fine TWC and Cox's Fairfax County system because they "apparently willfully violated" the requirement to support third party CableCARD devices. Time Warner got slapped with a fine of 40 large, with Cox only getting half that at $20,000 -- this is in addition to the refunds both will be required to issue to affected customers. This is definitely a score for the little guy, and we sure are glad the FCC stepped up on this one, but luckily for all the parties involved, the Tuning Adapter will solve this problem long term. Now if only more providers would start making them available. [Disclosure: Engadget is part of the Time Warner family]
Are you stoked, Dayton? You should be. Time Warner Cable has just sent out fliers to select customers in the region noting that a baker's dozen worth of HD channels are on the way, which will bring the grand total in the area to 46. Reportedly, the outfit will be pretty much finishing off its switched digital video (SDV) transition, as all 13 of the newcomers will be delivered via the bit-saving method. Ready to check out the exhaustive list? Head on past the break, you lucky, lucky Ohioan. [Disclosure: Engadget is part of the Time Warner family]
