What video processing technology does the iScan VP20 use?
The iScan VP20 uses a SiI504 chip to deinterlace incoming Standard Definition signals (480i/576i). The 10-bit scaling engine is a custom design of our own which introduces minimal phase and amplitude errors and provides better performance than we’ve seen in competing products. The scaler can scale up or down, so it can handle all types of aspect ratio conversions, unlike some other scaling products. Anchor Bay’s technology is known as Precision Video Scaling II™. For fixed pixel displays (plasma, DLP, LCD, LCoS), all Standard Definition signals have to be deinterlaced and then scaled to the native resolution of the display in order to produce a correct picture. The same is true of 720p and 1080i content, if the display does not have a native resolution of 720p or 1080i respectively. Using the iScan VP20 to upconvert signals to the native resolution of your fixed pixel display should in most cases allow you to automatically bypass the video processor built into your display.
