Mark has a serious issue at his install, he sits very close to the image.
This can be a serious issue as the artifacts of compression even when perfectly scaled will be obvious. I have always preferred at least 3ph back. I prefer 4ph on MPEG encoded standard def originated material. HiDef is different. There are well documented reasons for this I will not jump into here. While the Teranex can do amazing things it does not remove MPEG compression blocking and mosquito noise that was added to the source. These issues alone make me want a further distance back.
Line structure is another issue. I am of the mind set that a lower scan rate is better for picture quality on a CRT. Indeed I have seen many people discover this when the HTPC forum here suddenly discovered dropping the frame rate improved picture quality on a whole range of CRT projectors.
I do not want to use 1080P48 or 72. I like 1080psf48 because of its low scan rate and better picture from a CRT. 1080P48 while it -may- improve scan line visibility from a position that's very close to the screen it will degrade other aspects of the picture quality from a CRT.
All the professional DAC's don't support P48 simple because no one sees a need for it. Now that 24P is more of a standard, yes I feel it will come. Will it be a better picture is another point of debate.
I could have one made. It would cost me a lot to do. Im not sure I see a need.
Mark prefers a very close viewing position and really dislikes seeing line structure. This is a issue. I don't feel there is a good answer to this even with unlimited power from the Teranex. As I increase the number of lines and frame rate I increase the scan rate and degrade the picture as the electronics have less time to settle per pixel.
The Barco may also have a issue with line pairing. This is where 2 interlaced fields land on top of each other making line structure quite visible and very annoying. This can also happen on progressive. This was a very serious and difficult issue on the projector I make and I have spent a lot of time removing this issue. I even created a test pattern to help isolate the problem. Most CRT projectors today have issues with line pairing and landing each fields lines in exactly the same place each time. I have almost elminated this issue on my CRT.

The 3 board Teranex has 76,800 cpu's. This is unlike any normal scaler. It loads all those CPU's with software for each specific conversion. So for example if you do non anamorphic, that a different set of stuff from a anamorphic. Each format conversion loads different software. So the whole CPU structure does just that one thing, for example 480I to 720P is different then 480I to 1080psf24. The entire machine loads stuff for just one thing say 480I -> 1080psf24 anamorphic.
So all the hardware is dedicated to doing just exactly what you want and no extra space is wasted.
Most other platforms chips have to do many things and are hard coded for these even if you don't use them.

Rest assured they have plenty of room for additional math
This will become obvious shortly as Teranex has decided to address the Home Theater market specifically.
I cannot discuss this further..

This chip is a recently declassified technology developed using hundreds of millions of dollars by Lockheed Martin. Its not your normal chip or technology. The basics are still in use in highly classified stuff now using a chip that's 2 generations newer then this chip.
Its not a FPGA, ASIC or a DSP engine. Its patented and its called a GAPP (Geometric Arithmetic Parallel Processor). its a LSI and its number won't help you. There are 1024 numerical 1 bit processors on each chip, 25 chips per board, 18 layer board. They come in 1 board, 3 board and 6 board versions. The machine can do trillions of operations per second. As I/O is also a issue a board of 25 chips can sustain over 3GigaBYTES per second of I/O. 10 times the needed rate for any uncompressed HD.
Some of the unclassified technical details are at:
Teranex's web site
Overall its a unique massively parallel video processor. Its like a Cray for your video.
Indeed we have only begun to explore what it can do
I think the future holds many new things from Teranex.

Crestron control. This is odd as the RS232 control codes have been available for, hmmm, lets see, at least a year and a half. I have had working Crestron for over a year. Its fully functional 2 way RS232. Indeed you can also do TCP/IP if you want from Crestron if you want. It also has contact closure that can choose presets.
Its very controllable.

What makes its picture so good ??. As Teranex has decided to simply not tell a sole and not patent as they feel the secret is quite secure in the military chips, Im not sure we will know any time soon.
Rest assured its amazing.
I saw someone say it was not as good as DCDI. Interesting as i have seen the DCDI test disk played through the Teranex and it was perfect I think I will dispute this. This could have come from older software mabey on the Teranex ???.
The adaptability, future proof nature, and amazing picture quality do place it in a class of its own. Its also VERY VERY easy to use.
