DVD for distribution of HD shot feature?

H.264 is part of the MPEG-4 standard, they're sometimes used interchangeably. According to Wikipedia, H.264 is identical to MPEG-4 Part 10.

So you're getting 18-megabit MPEG4/H.264? I'll bet that looks pretty good... we're stuck with 19mbps MPEG-2, and there are times where it looks just awful, especially on 1080i broadcasts... but MPEG-4 is roughly twice as efficient, so one could say that you're getting the equivalent of 36mbps MPEG-2... way, way better than what we get here!

The ATSC was supposed to be considering adding H.264 support for US broadcasts; I don't know how that would work with existing tuners out there, but man that would be sweet if they would! H.264 looks like the next big thing going forward; HD-DVD and Blu-Ray are both using it.

I wonder if JVC would be bold enough to skip MPEG-2 and make their new GY-HD7000U's 1080i mode use H.264 instead? Or Panasonic's VariCam II? That would be pretty darn cool, especially if the ATSC adopts it and Europe already broadcasts it...
 
I just checked out internet for HD1 and I'm not sure for the bitrate anymore... A PDF-document from Euro1080 (old name of HD1) says "22 Mbps" and the HD1 page says " Symbol Rate: 27.5 MSymbols/sec" and I remembered 18Mbps...

Note: HD1 is already on air, BUT the program is still limited as Europe is still at the very beginning.... so there is a lot of "what is HDTV?"-demos to be seen on HD channel(s).
 
Barry - of course you're mostly correct (as always ;o) .. but I'd like to add that at least here in europe there's another possibility in getting HD video/audio distributed directly to a cinema that's equipped with HD projection (at least if it has local storage) -> simply putting HD MPEG2 on a DVD-ROM (or of course multiple as every movie >30mins in HD requires more than 4,5GB ;o). You can simply take the same format/encoding that you would need for distribution via satellite... but since you're bitrate is not that much restricted you normally would encode this with a higher bitrate at around 30-50Mbps...

More and more theaters here are getting equipped with HD projection as forced by a cooperation with the aforementioned (by cici) Euro1080 HD channel (the first HD channel in europe) ... initially to show live events (concerts but mostly soccer ;o) that get distributed live via satellite to the theaters.
 
DVD Players with DIVX (now quite a few) can play back HD in MPEG4 format. We don't have an HD TV, so the result was downrezzed, but it was interesting seeing HD (some video and graphics we shot and uprezzed for this test) played from a CDR.

How do they transmit the HD image to the TV? Component? HDMI only?
 
Pmark23...

I've refrained from picking up a divx Dvd player because I wasn't sure it would play HD.... because no HD was mentioned.

Now that you've confirmed that indeed it does, I'm heading over to the computer store to pick one up (they don't do returns... hence my hesitancy. The staff knows nothing about HD compatibility... they say, "Look up the specs on the net"."

At the moment my understanding is.... mpeg4 is h.263... so I should be able to play back h.263 encoded hd video... please correct me if I am wrong.

Something to stick content on when the HVX arrives in December.

The unit I'm looking at is about $60 US, cheap enough to tide me over until the HD DVD/bluRay war is over.

at least europe already has a channel, here in Israel it's still not even close. there are only a few HDTV plasma screens and projectors. that's part of the reason I'm not in a hurry to get the HVX, I'm probably going to wait another year for the HVX200a or whatever comes next. by then panasonic will fix all the small details like they always do and the memory cards will be much igger and cheaper

AAAieee!!

I picked up an mpg-4 divx capable dvd player today.

It will not play the little HD mpg-4 test I did. It just shows black, and the counter won't progress.

It's quite possible that HD mpg-4 is a much later version that wasn't implemented in my player. As far as I know, only the LInkplayer is advertising HD capablilty (for quite a while now).

Perhaps I didn't encode properly (used Divx6 with Prem Pro.)

What DVD player did you get?
