Please make try to get it into the shootout if the fellas will allow and the unit gets there in time!

PS I'm thinking about pairing it with a Denon 3930 so deinterlacing isn't as important as scaling......although it would be greate for it to do 1080i inverse telecine for HD content.

clear matrix pro is what it uses and the company info [above] seems to indicate motion adaptive on a regional basis. jeff.

The de-interlacing algorithm is our own developed for the last 6 years. It far too complex then any of Bob and Weave types. It is proprietary. All I can say is that we use motion adaptive techniques to de-interlace video by adopting different mathematics more suitable to type pictures processed such
as: film, video, 3:2 phase, 3:2 mistakes in production, noise, vertical detail, horizontal detail, graphics overlay and some others parameters. All of these estimates are taken into account before deciding how we calculate value of each pixel separately.

I hope it helps.

Thanks,

I'll take it from your silence that the iSynch didn't get there in time to make the shootout. Still would live to hear your thoughts!!!

iSync HD SD and HD programming:

This is where this VP really shines. My Sony A2000 must scale and process all signal to the set's native 1080P resolution, but with some programming (noatably SD and some HD material) it is not very adept. For example, SD from the satillite box appears soft, so much so that I prefer to watch any SD sports on my old CRT television. Also, with HD sports (720P and 1080i) wither off the dish or over-the-air braodcast there is something I'll call "live grass" (for lack of a better term) where clumps of grass that look sharp and detailed when the camera is still turn into blurry clumps when the camera pans horizontally. The crowd detail also often is riddled with subltle noise that you would not be worried about it the signal were SD, but not in HD.

I've only tested connecting the HD box to the iSync via component video and then onto the TV via HDMI. The picture qulality wiht the HD box out put set for native recorded resolution of the material (720p for ESPN/ABC and 1080i for all other HD channels or any resolution for SD programming) resulted in a much improved picture. iSync processed SD was now sharp and very wachable and the annoying video noise and "live grass" in live sports programming were gone in the Monday Night Football game I recorded earlier this week as test material.

I've yet to calibrate the TV or tweak any settings on the iSync or test my front projector with this VP so there is much work to be done. I will continue to report my impressions here. Happy Thanksgiving.

iSync HD Review First look:

The iSync HD arrived yesterday. It's my first external video processor so as you can imagine I'm thrilled- Christmas on Thanksgiving! It's a low profile unit at 1.5" tall, only about 8" deep and a standard 17' wide. It was easy to find space in my rack, made difficult only by the fact that the instructions indicate you need to keep it away from major heat sources (amps and in my case the satellite box/HD recorder).

With black box in place (yes they sent me the black one and not the silver one the AVS powerbuy indicates) I moved on to look at what I had been hoping from an external VP, that is - beautiful pictures. Last night I could only get an initial impression. There is quite a bit of work involved in any kind of detailed review so it will take some time to fully determine if this black box does any thing useful and more importantly for what specific type of source and programming material combinations.

Okay enough small talk. I connected DVD player (Oppo digital 990) to iSync HD and Sony 60" A2000 (with 1080p input) via HDMI. I only reviewed a movie so far and will look at test patterns at some time in the future. The best result was found with the the DVD player outputting it's highest resolution (1080i/60) and having the iSync deinterlace this to 1080P. The differences were subtle but visible on Mission Impossible III. During fast action the picture was smoother at times (fast action). For example, there is a scene shot from helicopter where the MI team is travelling in vehicle across a bridge when all hell breaks loose. The bridge railings wizzing by as the camera follows the car along the bridge and the ensuring crash / battle scene looked smoother and more natural. The PQ directly from the DVD players at 1080i with the TV doing the deinterlacing was okay, but a subtle "choppyness" (if that's a word) was evident. I also tried 480i signal via S-video, but PQ was definitely not as sharp with processing or passing through with this approach (or w/480p for that matter). I plan a 480i test over component tonight. Even though the documentation says that the iSync does not support 480i input over component, it does.

First impression with upscaling DVD player was positive with subtle, but noticeable improvement in fast motion using iSnc to deinterlace 1080i signal from my upscaling DVD player to 1080p native resolution of my SXRD TV. I also note that edges were improved making the overall picture appear sharper. I was a little disappointed not to see a huge difference, but see my next post below for my first impression on how the iSync handles SD and HD material from a satellite box.

I've only tested the 480i HDMI output from the Oppo DVD player and this resulted in a "not supported" on the front panel input indicator. I assumed it woudl do the same if I output 480i from my HD box. I will give this a try and report my finding here.

PS: Great first hand info. Keep it coming. I am currently debating between ISync and Lumagen HDP. This info helps me to decide on the VP to buy.
