The DVI-D inputs default to having their HDCP inputs turned off. This is because an HDCP input can only function properly when the output monitor is also HDCP compliant - thus by forcing the source to disable HDCP will help with compatibility and ease of use with non-HDCP displays connected to the output. However, for sources where the output ALWAYS has to be HDCP encrypted (e.g. devices outputting a high-resolution image),
HDCP is a copyright protection system (High bandwidth Digital Copy Protection). Therefore its primary aim is to prevent protected material (usually High Definition video) from being copied. It does this by encrypting the video signal between the source (e.g. DVD player) and sink (e.g. display). To do this, each source and sink must be HDCP compatible and negotiate with each other to create a secure link. They do this by exchanging 'keys' and working out a secret encryption 'password'.
Almost all CORIO products will output a YUV signal along with separate syncs (H & V) on the HD15 connector. This is because the signal is from the same chip as the RGBHV signal.
There can be several reasons why a converted image may appear blurred, and these depend on the way the unit is being used: DOWNSCALING AN IMAGEIf you're changing from a high resolution to a low resolution, you'll never get quite the same image quality on the output. This is because you're 'squeezing' multiple pixels into fewer pixels and thus losing information.
There are two types of frame rate conversion employed in CORIO2 products: 1. FRAME ADD/DROP Units supported on:1T-C2-100 to 1T-C2-750 C2-1000, C2-2000 (non-'A'), C2-3000, C2-4000, C2-5000, C2-6000, C2-7000 series This method will add or drop a frame in order to convert the input to output frame rate.
Dual-link DVI is a method of combining two DVI channels into one higher resolution picture. You can't combine any two channels you like - thegraphics card (or DVI source) must support this feature and use extra pins on the DVI connector for this. 'Normal' DVI is single-link anddoesn't use these extra pins.
The maximum DVI-D input is 1280x1024 @ 60Hz (pixel clock of 108MHz). If you feed a higher resolution into the unit, it will not display the image correctly. Please note that What is EDID? will normally 'tell' the computer what the maximum resolution of the scaler is, so it's best not to try and force an output higher than the receiver can cope with.
