I have the following equipment:


Sources: PS3 and HD Cablebox

Scaler: DVDO-HD+

Projector: RS1

HDMI Swtich


I was wondering if this config would work and allow me to put an anamorphic lens in place and run a constant height set up.


1. Output 720P and/or 1080i from the PS3. Someone told me that 1080p blue ray movies are actually sent out using 1080i as their container.


2. Set my cable box to output whatever it gets in.


Switch via my HDMI switcher.


Let the DVDO handle the anamorphic stretch to the JVC for the lens.


What will I lose? I do game, but as far as I know, none of the games really use the full HD screen. So can I get my HD+ which will (in theory process 1 DVI (RGB or YCbCr) processes 480i/p-60, 576i/p-50, 720p-50/60, 1080i-50/60) to handle the stretch for me reliably?


Will I be able to stretch BluRay movies so that they come out at 2.35:1?


Is the Panamorph 85 compression lens sharp enough for 1080P?


Thanks,


Raoul-Sam

My gut feeling is that it will work fine. My set up is a HD+ feeding a Mits HC1500 (720P) 1:1 mapped. I don't have a Blue Ray player but if I send the HD+ at 1080i signal from my cable box, the HD+ will send a 720P signal to the HC1500. If the HD movie is in 2.35:1 the HD+ will do the required vertical stretch. I would assume that if you send your HD+ a 1080i signal from you Blue Ray player the HD+ would pass that through and the PJ would de-interlace it to 1080P.

You do not lose any resolution by sending 1080 interlaced, when the source material is 1080p24 or 1080p30, if your display correctly de-interlaces 1080i. 1080i60, 1080p24, and 1080p60 all contain exactly the same data when the source material originated as 1080p24 (films). 1080i60 also works correctly (no loss of any picture info) when the source material originated as 1080p30 (some concert HD disks and theoretically some "films" that were shot as HD digital at 30fps, but I have never heard of it being done that way).


The only time that 1080i60 loses anything is either: display de-interlacer does not work correctly, or the source material originated as 1080p60 (video games).


If your display de-interlacer works correctly, then there are clear advantages to sending 1080i60 vs any other format (1080p24 or 1080p60).


Advantage of 1080i60 over 1080p24 - often the 1080p24 output option on HD players is a "forced" output - the device always sends 1080p24 even when it is not appropriate. Many of the extras on HD disks are either not 24p or the overlay mechanism was not designed to work with 24p. Also, any 30p sourced material will not look its best (concerts, etc) when sent as 24p.


Advantage of 1080i60 over 1080p60 - 1080p60 has telecine judder inherent in the 24p to 60p conversion process. No display can remove this judder, and AFAIK only the DVDO scalers that use PREP can get rid of it. 1080i60 is half the bandwidth of 1080p60, and this can become a factor in long HDMI cable runs. A cable that has drop outs and other problems with 1080p60 can often pass 1080i60 without any problems.


PS: "Deep Color" only exists on video games, so it is not a factor for HD disk based media.

So. I set up the PS3 to pass 1080i60 as the output signal to the scaler all the time for this to work with the DVDO HD+?


There are no games that do 1080P yet so I'm not worried.
