To playback HD smoothly, you already need a 3GHz processor. Imagine how much CPU power would be needed with the video needed to be decoded first and then played back.

I would assume less compression would need less processor power but more memory.

So 3Ghz wouldn't be needed.

More memory, and more memory-transfer speeds...

Unless you know of a cheap, easy, and effective method of delivering 160MBps...and no not IDE-RAID...

well, how are they playing the content for the stations?

Broadcast HD is compressed.

Also the problem is delivering that kind of data rate to the recipient. That kind of data is OK in a production studio, but you can't broadcast that much data & you certainly can't distribute it in a nice compact package (DVD).

There really is no reason to anyway, the cost is simply enormous compared to the marginal benefit in quality.

I was under the impression that OTA was uncompressed, or at least moreso than sat/cable?

It's all compressed. But Sat (DirecTV and Dish are the worst) compresses them more than OTA. OTA is the least compressed when stations do not have mulitple sub-channels (like weather or news).

DirecTV has done the same thing with their HD channels that they did with their SD channels: Compressed them to the point that they look like sh!t.

Watching an action movie in HD on DirecTV is horrible. Especially water and fire scenes. It breaks up into the worst macroblocking I have ever seen in HD.

It was MUCH better just two years ago. Then they started cramming more stations onto a transponder and overly compressing the signals. Just recently, it got even worse when they added a bunch of premium HD football channels.

Needless to say, I will be switching to Voom this year. The quality of HD on DirecTV has become so bad I'm willing to take the risk of Voom going under.

However, the difference between 19mb (OTA) and 12mb (DirecTV) is astounding. DirecTV just two years ago sent their HD out at 18-19mb. Now it's more like 12.

When it was at 19 mb, it was nearly flawless. At 12 it looks like complete crap. Not only does the slightest movement cause macroblocking, even static images are not as crisp.

Voom, here I come...

THat's what custom ICs are for.

I've DLed avi files of Shreck, Terminator 3 and Matrix revolutions. (You can find these by the way and they ARE NOT FAKE). The full movies compressed fit on one DVD. And I have to tell you, you wouldn't know it's compressed. Well, I'm sure you coud, but the quality is still mind blowing. Makes DVD movies today look like cr@p.

Right now it is a money issue. 4k projectors are starting to appear from the manufacturers. Reportedly, the pictures are very good. The storage issues have been satisfactorily overcome using compression

The problem is that you can install about four sets of conventional projectors for the cost of a single 4K digital installation.

Believe me, the major studios are desperate to get rid of the lab/film/transportation costs involved with conventional film. The exhibitors are in no rush as it does not benefit them to spend more money to save the studios money. There is no incentive, yet.

A Voom press release you might be interested in.

Think you missed my point, you can't distribute uncompressed HD.

Compressed HD is (relatively) easy.

Uncompressed will probably NEVER be used.

It's not used for standard definition, why would they use it for high definition?

The downside currently to Voom is DVR option.... but their changing that once they come out with the Voom HDDVR and their home solution option which is awsome...

Our upcoming Whole House Solution extends the power of our DVR throughout your home. With a single click, you can pause live TV and HDTV, then go to another room and pick up where you left off. It also connects your TV and PC entertainment like never before. You can access your PC and enjoy digital music and photos on any TV in the house. That's VOOMing!

It looks like they will be adding transponders to handle the expansion, correct? If so, that's good news.

Will that be enough? Or will they start compressing like Dish and DirecTV?

BTW, Voom is coming out with HDDVR this year. AND they are offring a "whole house solution" that networks the DVR to be usable at any TV in the house.

That's what they are saying at least.

Since they make a marketing point of offering so much quality HD content it wouldn't make much sense to downgrade the quality just to carry more channels. They would just end up competing with a very similar service to DirecTv, which I doubt they want to do.

Well, I have until summer before I do anything. So I guess I'll keep my ear to the ground.
