I recently bought a DVDO iScan Ultra external video processor. What is it? That can be hard to answer in concise, layman's terms. It's funny you ask that as my folks visited tonight and looking at the DVDO, they asked what the new box is. They are totally NOT into the home theater thing so I didn't even begin to try to explain it to them....too complicated to water down for a non-enthusiast. But I will try to explain here.
My Ultra converts 480i to 480p....and does an awesome job. I have an RPTV that will display 480p natively so that is an important resolution for me. The Ultra's Sil504 chip is known as one of the best deinterlacing chips ever....and the chroma filter DVDO includes is a nice touch to help clean up the ICP error. I bought it mainly for my DVD player, but it will also deinterlace and "spice-up" cable, satellite, laser disc, VCR, etc.......and it can act as a sole video switcher and allows calibration for each source. It also has cool aspect ratio controls.
The Ultra is a simple box compared to other external video processors. DVDO's newest offerings will output and scale other resolutions. They are very nice so one can 1:1 pixel map to their display. i.e. perfectly match their display's native resolution.
That's some basic info. Check out the Video Processor forum here at AVS for more info!
