Bottom Line
From where we stand, frequent and quality-sensitive video watchers will find Netflix or Blockbuster to be better month-to-month values for HD video rentals than Apple TV or on-demand cable services, while Apple TV provides an option that’s in the upper middle of the pack on quality and the best on convenience, so long as you’re willing to pay the $229-$329 cost of entry. The question is: are you?
To my eye, Apple TV is looking good, especially since it is running HD at 720p.
I have an Apple TV on my lust list. I may wait until it supports 1080p. The Robert X. Cringely’s weekly column I, Cringely posting Blu-ray Blues: With the HD War Over, Why Aren’t We Seeing Blu-ray Drives in Apple Computers? discusses and hypothesizes about Apple and 1080p.
Here are some interesting tidbits from the posting.
Jumping to 1080p is a huge challenge for iTunes. Just look at the comparative sizes of the QuickTime HD trailers for the upcoming Indiana Jones and the Kingdom of the Crystal Skull on Apple’s own web site. The 480p trailer (that’s standard definition and slightly better quality than the 640-by-480 shows most people download through iTunes now) requires 47 megabytes while the 720p file is 78 megabytes and the 1080p version requires 126 megabytes. The trailer runs just under two minutes (1:51). The three prior Indiana Jones films were 115, 118, and 126 minutes, respectively, so let’s take the average and figure this new movie will come in right at two hours in length. Extrapolating from the size of the trailer, then, a good guess about the ultimate file size for the H.264 download versions of this upcoming blockbuster are 3048 megabytes, 5059 megabytes, and 8172 megabytes, respectively.
Apple faces a number of challenges offering files of this size for download, the least of which is economic. Yes, it will probably cost Apple four times as much to offer downloads of a 1080p version of a movie than its 640-by-480 version, but the market is already expecting to pay an HD premium, at least for a while, so money isn’t really a major factor. The real speed bumps are the sheer impact of a true volume HD service on the Internet, itself, and the sad fact that most Macs can’t even play 1080p video. They simply aren’t powerful enough.
As for giving Macs enough grunt to play 1080p video, I explained more than a year ago that Apple has privately committed to putting an H.264 encoder/decoder chip in its entire range of machines. That specific chip began sampling last July so Apple should be able to start shipping the new Macs any time soon, certainly long before Christmas.
Most interesting, Robert.
