As one poster put it. "Looking to the future". Just reading the thread header, I started to invision a Apple Set Top Box connected to a "BROADBAND LINE" (for that klondike that still has the 56k v.2 dial up connection). Apple has the movie hosted on thier servers and you can play, pause, fast forward, rewind, etc. like on MOD (movies on demand). I don't know, it sould cool. If it is true, we may have a lot of Shizzle coming down the pipe from apple my Nizzle. I really do believe that Apple is looking towards the future.

If by "over 17" you mean 18. :) There are 18 ATSC formats. All of them are standards. Six of them are HD. Two of those are used for HD broadcast.

The 18 ATSC formats are:

640x480 @ 30 Hz interlaced
640x480 @ 24, 30, 60 Hz progressive
704x480 @ 30 Hz interlaced
704x480 @ 24, 30, 60 Hz progressive
1280x720 @ 24, 30, 60 Hz progressive
1920x1080 @ 30 Hz interlaced
1920x1080 @ 24, 30 Hz progressive

Only 1280x720@60 progressive (720p) and 1920x1080@30 interlaced (1080i) are used for HD broadcast. 1080/24p is often used for HD production, but is converted to 1080/30i for broadcast. ABC currently broadcasts 720p, and Fox has committed to 720p by the fall. Fox currently broadcasts 480/30p widescreen, but will be phasing out those broadcasts in favor of 720p this year. Everybody else broadcasts 1080i.

Don't forget compression. In the digital world, not all of the complete frames need to be sent, only the changed portions.
Depends on what codec you use. For MPEG codecs, this is true. They use inter-frame compression. For Pixlet, DVCPRO/DVCPRO-HD, and some other codecs, they use only intraframe compression.

None of that matters, though, because we were talking about the ratio of NTSC to HD and half HD in terms of pixels per second. When you throw pixel packing (as I mentioned) and compression into the mix, there are too many variables to keep track of. It becomes impossible to meaningfully compare NTSC to HD.

For example, digital SD is often, but not always, broadcast at 8 Mbps, while digital HD is often, but not always, broadcast at 19 Mbps. But there are so many exceptions to this rule that the rule itself is meaningless.
 
Observed Bandwidth

rbog:

Speeds to the US can still reach 2000KBps but they don't reach full 100mbit.

To test connections I often DL Mac OS 9.2.2 update (83MB) from the Apple site.

My ADSL connection takes 13-15 minutes.

My friends FTTH connection takes 7 to 12 seconds. Yep, DL'ed 4 times in well less than a minute. Average time was 9 seconds for a transfer rate of 9.2MB/sec.

Best rate was 11.85MB/sec (7 seconds).

So FTTH was close, but not quite 100Mb/sec.

A few thoughts...

1. People already download movies, just like they download music. It's not a big deal anymore!
2. TiVo has a Rendezvous-enabled TiVo box.
3. It's called copy-protection. Certify the computers it can play on and play it on other media only by Rendezvous streaming (on the TiVo).
4. Achieve DVD quality and cut out the middleman, or at least the middle medium, to save money for everyone involved.

How could Apple NOT be working on this?
 
or, cutout the middleman (er, middleBot) and plug a cable line directly into your mac. Apple sets up it's own VOD station and viola... A very large rabbit out of a very small hat.

Am I going too far? I consider myself an 'ideas man' (JK)

Can't Apple use this for movies ...

The "half of full res" option for PIXLET , the wunder codec ... from
what SJ showed us recently , it could really do the job.

Along with some G5 magic coming soon, it could be an incentive for us to buy a coming iMac ---- get movie downloads if you get this G5 iMac with an ADC socket... and/or a 19" screen and surround sound speakers :)

A quick look at the source code reveals that the movies (which are hi-res) are hosted on Apple's QT servers.

--------------

I downloaded several to 800 MHz G4 iMac/ 15".

They seemed choppy -- but with QT Pro, I was able to select "Play all frames" from the pull down menu.

This muted the sound, but I got perfectly smooth 30 fps video.

It's pretty nice.

I suppose what I'm trying to point out is that, the movies are being served on Apple's server while being under a different domain.

I can't remember a time when this has happened, I mean, why would Apple serve for something else.
