HD TV -- to 1080p or not 1080p
Peter Putman over at HDTVexpert has a very thought provoking article on the downsides to the so-called 1080p (or "full HD") sets that are just coming on the market. Having just bought a new HDTV set capable of only 720p, and drooling over the much more expensive 1080p sets available, this article had a lot of interest for me. I made the decision not to buy a 1080p set based on budget ... I'm not going to spend $4-5K on a TV right now. But part of me still longed for the "true" HD capabilities of 1080p ... or so I thought until I read the article.
The article points out that 1080i (i is for interlaced) is the current and future king as far as HD content goes. According to Mr. Putman, none of the current technology for filming, producing, or broadcasting HD content works at 1080p resolution. He also points out that what 1080i content that is out there was produced with quite a few short-cuts -- in effect it's not much better than 540p (DVD quality). So in effect, if you do buy a 1080p set not only will there not be any 1080p content available (not on your Satellite, Cable, DVD, Tivo, etc.) but even if there was it was probably upconverted and will look pretty bad since taking a low quality signal and displaying it on a 1080p set will just magnify the underlying problems in the signal.
It isn't clear to me how HD-DVD fits into the picture; also, I wouldn't be surprised if in a few years we start seeing more devices capable of outputting a 1080p signal (by upconverting). You'll still have the issue of an upconverted signal not being as good as a true 1080p signal (and possibly worse than a true 1080i signal) but I think the bigger, faster, more demands of consumers will drive TV manufacturers to constantly raise the bar on resolution. As HD TV prices drop, manufacturers will use features like 1080p upconversion as an incentive to buy their TV over the others.
