A system the REST of the family can use??

post #1 of 7
Thread Starter 
First, I am committed to CIH - my new theater already has a curved screen wall for a 2.4 10' wide screen.

I did a CIH system with my LT150 and ISCO II in 2001. That was accomplished with an HTPC. No one could use the system except for me. :-(

I would like to reuse my ISCO II, but I would like to make the system such that someone else could use it.

Sources:
-DVD
-HD DVR

Projector:
-you tell me ;-)

Lens:
-ISCO II

It seems to me there are three places the scaling could take place:

1) projector - probably possible with some projectors to configure one input to scale to a certain size, but practically speaking, someone is going to have to toggle through some options on a remote to get it right. I read about projectors with vertical stretch, but not about those with horizontal stretch, which i presume is necessary for non-anamorphic titles.

2) htpc/scaler - similar limitations to the above, except that with the HTPC, it is possible to configure each disc individually.

3) source - either source could potentially do the scaling

I'm curious what others are doing. Is it unrealistic to have a system the novice can use? If so, please tell me how you're doing it. :-)

Kelly, if you want others to easily operate the CIH system, then you need (sorry) to ditch the complex processor (HTPC) and adopt the more simplistic approach of plug-n-play. A fair few of the new 1080 projectors (SONY WV60, BENQW1000 and soon JVC RS2) now offer built in scaling modes so that you can simply switch ARs on the projector's (or your own learning) remote. The lens has to stay in place all the time, (ISCO II has to anyway) but it is much simpler to operate.

These systems work with both HD DVD and BrD...

It would be nice if scalers would auto-detect the native AR of the incoming signal and auto stretch. Unfortunately there are some issues with doing this, but Lumagen has said they will look into it for the HDx line. About the closest you can come at this point is an almost automated setup with two buttons on your remote - one for 2.35:1, and one for 16x9. Not too difficult for people to figure out - if the image is "small", you press the "big" button.

I would LOVE to drop the HTPC from the picture, if only for convenience reasons.

Is there a comprehensive list of projectors that provide built-in scaling abilities? What do they call this feature, or does it vary from manufacturer to manufacturer?

To me, on-board projector-based scaling seems the easiest, but most of those projectors (ie, Sim2) are pretty expensive. Perhaps less than other projectors + a scaler.

Would this HDMI switcher + video processor provide the necessary stretch abilities? The owners manual states the following, but its difficult to tell.

http://digitalconnection.com/Product.../kdhdmi4x1.asp

Your HDMI 4x1TM Switcher can perform output Aspect Ratio processing, including options to prevent monitor burn-in for Letterbox or Pillarbox images:
Full
Letterbox, Pillarbox
Horizontal Zoom, Vertical Zoom, Horizontal and Vertical Zoom

You can also scale the selected (switched) HDMI video input to match the native resolution of your display:
Using world-renowned Key Digital® Clear Matrix ProTM and SDSTM (Super Digital Scaling) technologies to deliver world-class scaling
Supports all popular source and display formats and resolutions
1. H Zoom (Horizontal Zoom): This H Zoom feature is particularly useful for some Plasma owners, who may want to stretch the image to fill the screen and avoid the nasty burn-in. If the input signal is a Pillarbox, Horizontal Zoom extends (distorts) the image from left to right to fill the screen. For example, when a 4:3 movie is upconverted to HDTV in a studio, it may be simply released in the Pillarbox format, with black bars to the left and right of the image in a 16:9 window.

2. V Zoom (Vertical Zoom): This V Zoom feature is particularly useful for some Plasma owners, who may want to stretch the image to fill the screen and avoid the nasty burn-in. If the input signal is a Letterbox, Vertical Zoom extends (distorts) the image from top to bottom to fill the screen. For example, it is very common for a widescreen DVD movie to be presented in Letterbox, because the original movie may be captured in 2.35:1 Cinemascope or some other Aspect Ratio that creates a small letterbox in a 16:9 window.

3. HV Zoom: This mode simultaneously stretches the image uniformly in both the Horizontal and Vertical directions, using the same ratios as in H Zoom and V Zoom. This Zoom mode may be preferred over the H- or V-Zoom, both of which geometrically distort the image. Because the image is Zoomed, there will be a slight loss (cropping) of the image at the top and bottom for Pillarbox sources, and at the left and right for Letterbox sources.

Yes, this unit does the necessary crop/stretch needed for CIH with BD or HD DVD as well as SD. I just picked up two of these units from their store in Huntington Beach. I tested it out with their RS1, HD DVD source, and my HTB anamorphic lens and it works perfectly. I haven't used either of my units yet so I don't know exactly which mode to use, but it looks like one of those you mentioned does it. They also updated the firmware for me which aparently fixed some problems with 720p sources, so it should be trouble free! They were very helpful and seem to be in the know when it comes to CIH. They have an enormous curved 2.35 screen coming soon for their demo room. Hope this helps.

Very helpful, thanks. What I was thinking is:

-connect all sources to the switcher via HDMI
-output one audio signal from the switcher via PCM to my old Lexicon (still love the sound)
-output one HDMI to the projector

That way, all audio/video switching is performed by this unit, and I can program that through the remote. Actually, it says "smart switching", so its supposed to auto-sense, but who knows if that really works.

We are still a ways off, but just so you get the idea:



That's a 126" wide, 2.35 curved AT screen wall. :-)
