CableCARDs and HDTV
An anonymous reader writes: "HDTV is the next big thing. I attended the NAB conference in Las Vegas last week and everyone was pitching HDTV or asking about it. DesignTechnica has an interesting article on CableCARDS, which allows viewing HDTV through a CableCARD compatible HDTV set without needing a set top box. Cable companies are required to enable CableCARDs with card-compatible HDTVs by July 1, 2004. So here's some questions: Has anyone heard of CableCARD? Is anyone planning on buying a CableCARD compatible TV? How many people actually get HDTV in their area, and how many channels? HDTV is so hyped right now but seems that there is barely any deployment."
That they're forced to follow?
between digital cable and direct tv satellite, I've always thought that a set top box hinders the viewer from the easiest viewing experience. A feture like picture-in-picture is lost. It requires you to program another remote, and for some people this is a pain. It can require the user to have two remotes, one to turn on the tv, switch it to cable input, and adjust the volume and then one to changed the channel and use the converter box.
For me it's not that big a deal, but for people who aren't engineers the logic of how to turn on the tv and change the channel is actually difficult for them to understand. Say for example, the television I purchased had a standard digital cable converter built in, it would make it a lot easier to use the service. Maybe it could work by the cable company sets up the firmware so make it more customized for their customers.
Maybe I'm missing something here, but I should not have two remotes to watch tv, and I don't think I should have to deal with programming those multi-remotes either. Finding the codes when those batteries die at this point in the game is a waste of time in my mind.
Maybe this issue of remotes sounds petty, but this would be one of the main driving forces in getting people to buy a new television if the sales clerk can relate this ease of use to them.
Blah you mix memes here.
The reason the government is involved is because airwaves are 'public'
Democracy works fine. Vote for people who will care about what you care about, and educate others to care about what you care about.
Refuse to purchase what doesn't suit you.
In the end companies will lose business, if you are right, and politicians who gain power will lose corporate financing.

For a CARD that goes into my computer so that I can watch digital CABLE. Now they've stolen the name with a completely different concept. What the fuck?

Look at it the other way: if the government were to declare that new TVs would have only 240 scan lines rather than 480, would your TV experience be substantially diminshed?
Picture quality does matter, especially as TVs get larger. It probably doesn't matter enough to junk an entire infrastructure, but this is a lot more about reclaiming bandwidth than it is about resolution. The new standard reclaims valuable spectrum and replaces it with a format that makes better use of the bandwidth.
Or alternatively, it's a way for the existing networks to grab additional bandwidth while fighting tooth-and-nail to keep from giving up the old one. Either way, the new picture is really, really pretty, when you can get it.
How many people actually get HDTV in their area, and how many channels?
Actually, nearly all of the networks in nearly all of the major markets are broadcasting HDTV. If you're not in a major market, coverage is far spottier, but a substantial fraction of the people in the US do live in a major market.
The number of people actually receiving the signals is pretty low, since the TVs are expensive, but the digital signal is there, in lower resolution. The actual high-definition content is pretty low, since it's expensive to produce (requiring new cameras and other equipment), and so people aren't buying the very pricey TVs. No content, no viewers; no viewers, no content.
It also doesn't help that we're still waiting on standards like high-definition DVDs. Supposedly that's busily being resolved. They're also finally starting to put out the high-definition content over cable wires (which many people in the major markets have) and satellite systems (which are immensely popular among people too far from a major market to get cable, and also among those who find the cable companies obnoxious).
Me, I'm waiting on a cheap digital-to-analog converter so I can watch the new signal on my old TV, since the signal is clearer than analog.
...to see what exactly HDTV-DVD will mean. 720p60? 720p30 1080i60 1080p24? If and when I'm getting an HDTV, I want to see movies on it. 2/3rds downscaling (1080->720) would suck (take 3 lines, combine down to two... far worse than 2 lines native). On the other hand, getting a much more expensive 1080 set makes no sense if 720 will be the standard, due to size constraints or whatever.
And have they finally agreed on a *final* standard that won't be cut off or downscaled later (analog, firewire, HDMI???). A TV isn't like my computer, that one gets upgraded or replaced quite often. They need to tell me what exactly I can expect to get, not today, but several years ahead. So far, they haven't done that.

The problem here is that you expect manufacturers to build to the 1080i/p standard before the technology exists. The best sets for high resolution out there are still CRT based, because LCD (and that goes for LCoS too) and DLP technologies simply don't offer more than 720p resolution at the consumer end of the market. In fact, there are no DLP chips out there that do more than 1280x720, and the high end of LCD Front/Rear projection is still 1366x768 (Sony HS-20). Only a CRT offers full 1440x1080i resolution, because CRTs are inherently analog technology from the electron beam out to phosphor.
If you want full 1920x1080 resolution you must either wait for LCD/DLP technology to progress to native HD spec resolution (probably two chip generations away before it hits consumer), or buy a very high end CRT based system. I have an HS-20 LCD front projector (720p native) and a Hitachi 51S500 RPTV; a low end model with three 7" CRTs and semi-decent optics. It only supports 1080i at 1440x1080. The better RPTVs use 9"CRTs, with better optics, but they're still limited to 1440x1080. The only "real" CRT systems out there that do full 1080i spec are commercial units for pre and post production, usually costing somewhere in the range of $25K - $30K.
Why is this? Because the scan times for 1080i and 1080/24p are insanely fast, and the bandwidth requirements are insanely high. It's not just a computer monitor. And with an RPTV, the convergence issues alone get in the way of full 1080i. Really, the upshot here is that full 1080i spec was written long before the technology existed to display such resolutions. Only today with the migration away from CRT to digital LCD/DLP chip technologies are we coming close to display devices capable of real 1080i. And note, plasma doesn't even come close.
Anyway, feel bad about it all you want, but I think the manufacturers are doing a fine job with implementing the standard given current technology. I note that my 51" RPTV with the higher resolution isn't much nicer than images projected against my 117" screen at 720p. Honestly, one can't tell the difference, though 480p from DVDs does suffer with such a large screen size.
The real PITA has been the fight over DRM and copy controls interfering with rollout of content and obsoleting old HD displays. There will be a lot of very pissed off customers once they realize their component only HD sets are worthless for HD content in the next few years.

1080p is not the only HD signal. You're forgetting about 720p and 1080i.
While I agree that many 480p only sets are being sold as HDTVs when they're really just progressive scan SDTVs, all you REALLY need is a 540p screen to be able to display 1080i signals and be a "proper" HDTV, which many displays can do.
Not to mention the amount that do 720p native nowadays (mostly RP and FP though, almost no tubes that I know of).
