Theres an italian in the house!

I was worried the bad weather would delay the driver but it made it here safe and sound.
I will not be able to comment on performance until later tonight but I did hook everything up and confirmed she is working. More to come!

Beaten to the punch.

Looks like a Ducati sidecar. Look forward to your comments.

Interesting. And that confirms it is not the C3X case. Similar, but not the same...

Yes new design, sharp looking machine. Going by memory its quieter then the 1080 C3X and quieter then the Marantz 11S2 sitting next to it.
The Host has an HD-SDI

That is the gateway to some seriously interesting stuff.

Loved that on my HT5k

The uncompressed kind.

The interface is used in the broadcast industry and handles uncompressed broadcast grade video. What you see on HDTV, which can be outstanding, isn't even close to the uncompressed files.

The standard can handle around 30 times the data rate of BD, and upto 60 in dual-link mode.

Ok it's been over an hour. How much time do you need Alan . Can't wait to hear your impressions. Have fun!

Intriguing. Looks like Sim may be thinking nextgen with HD-SDI when Bluray has gone the way of the Betamax and everyone is downloading UNCOMPRESSED day and date flicks to their nice little movieservers. Hmmmmm.....

Very perceptive.

The HT5k had it 2 years ago. The difference is staggering.

In my last place I was fortunate enough to be asked, and able, to host a number of screenings that made use of this interface. Incredible.

Hard to tell from the photo, but does it have 2 SDI BNC's? Need those for real HD SDI bandwidth. Yes, I LOVE my SDI'd SD-DVD player. Wouldn't consider using anything else for SD-DVD.

It has 1 HD-SDI BNC. You do need 2 for dual-link, but 1 connector can still deliver nearly 30 times the data rate of Blu-Ray.

Seeing uncompressed, pre broadcast, 1080 material was a revelation to me. This needs to be the next stage for sources.

Or a single 3 gigabit HD-SDI port. 4.5 Gig chips seem to not have made it to market, yet. As Belden pointed out its 3 gig certified coax was later also certified for 4.5 gig.

1080P does require either dual channel or 3 gig., 4.5 gig at higher sample and framerates.

Of course you are correct. Im not sure if these newer units have 3Gb ports.

I don't believe 1080P24 requires dual channel

Why all the hype over HDSDI? Many (not all) HDMI implementations are exactly the same. Meaning you can send the same uncompressed signal over HDMI. Go look in the Processors fourm for indepth discussion on this.

The cool trick is getting access to uncompressed HD. Even a DCI master is still compressed. Plus even broadcast grade HD VTRs are still compressed, the highest bit rate available being 880mbs.

Correct, it's actually less bandwidth then 1080i/60 but is padded out the same to keep the interface standardized.

There is no 4.5gbs SDI standard. 3G is covered under SMPTE 424 and 425.

Glimmie, I dont see any hype at all. Just passage of some basic information.

I think most people know that you can do the same with HDMI, its just a good option to have if you can use it. If you have access to the content, and connectivity, its a sweet deal.

I thought 1080p required 3G or dual channel.

If its not 3Gb, then its limited to 1080i as per SMPTE 292.

Of course its VERY possible Im missing something here. If I am, please straighten me out.

CM, it is all about bandwidth, 1080P24 requires less than 1080i60..

No reason to run Bluray at anything other than 1080P24 for 1080P24 encoded movies, and 1080i60 for video and 1080i60 encoded discs, and then let external processor or internal projector processor(if quality processor) convert to 1080p60. Actually the best way would be to run Native from disc

L, I understand the bandwidth comparison. I thought there was maybe a format issue, or some other BS, that I hadn't grasped.

Thanks for clearing that up.

Thats what I love about this particular part of AVS, there seems no end of information to tap into.

1080P/60 requires 3gbs uncompressed. However 1080P/24 fits into SMPTE292 as it is actually less bandwidth.This format has been around since 1999 and is the basis of most scripted drama production today.

1080P/24 can be translated to any world TV standard with historically acceptable artifacts, like NTSC 3/2 pulldown and PAL 4% speedup just as film has always done. It was developed primarily do to ABC adopting 720P while NBC and CBS went 1080i. ABC mandated they would not accept conversions from 1080i due to the motion artifacts. But as most drama shows are film origionated, conversion from 24P was OK. Naturally when a film is transferred to HD these days it is done frame for frame to 24P video hence the reason BluRay is mostly 24P. And with this standard a whole world of 24P video cameras were born and used today in place of film on some projects.

P.S. It's really 23.97P in the TV world because NTSC is really 59.94 and not true 60. But true 24P is also used when going back to film such as in digital cinema. And the TV flavor of 24P (that is 23.98) is really 23.98sF as it was made compatable with interlaced equipment.

But for all practictical purposes it is true 24P.

Alan, what are you selling to make room for this? I smell a deal

The Sim2 just kicked my Marantz 11S2 to the curb


I promise a follow up as soon as I can. I want to take some measurements to solidify what I am seeing but I think Sim2 are on to something.

A few quick impressions, you guys are in for a surprise.

Watching a scope movie with dynamic black on ( not using a anamorphic lens ) the black bars completely disappear. I even threw this on the high power thinking the bars would show up but still a no show. Turning off DB raises black and they are back. I would have never expected this level of black from any 3 chip DLP. We are not talking crushed black, shadow detail remains. Lcos now has some serious competition.
Toggling dynamic black on/off during a movie the difference seamed subtle but somehow its impacting mostly lower IREs.
The iris is positioned after the lamp before the optical light path so clamping down the iris always maintains full ANSi contrast. Open the iris all the way keeping dynamic black on, the bars remain gone. Dynamic black and lamp modulation seam to be working at the same time enhancing one another. For an example during a star field the combination of DB with lamp modulation ( the lamp increases ) expand dynamic contrast. Any little object of light ( if at 100 IRE ) remain at 100 IRE against black and jumps off the screen where without the modulation using just an iris the upper IREs would be dimmed in parallel along with the blacks. I am very impressed so far. More tomorrow night.

There's your deal Chris !

The scene in 300 when the boy returns home to become King Leonitus (he is standing in the dark with snow falling all around) is a nice scene of white objects on a black background. Actually the scene with the wolf is also very good.

Heck who needs CES.. just go to Alans house.

Alan, so you are not going to just test it for a while and sell it?

I was going to call first dibs.

Thats exactly what I was hoping to hear. That combination of techniques sounds killer.

Looking forward to some detail.

I wonder how long before they put that in the HT5000............especially with new filters

Thats where I was getting confused. I read a synopsis of 292 and it appeared to say 1080i. Reading it again, after your post, its actually very clear that 1080P/24 fits.

Thanks for the clarification.

Thanks Alan. On what size screen are you running the Lumis ?

Hi Alan,

Whats your impression on the lumis as it compares to the standard 1080p C3X?
