How to implement a DVI interface?

Nov 22, 2006 2 Replies

Hello, I have a project that I will be starting soon and it involves performing image processing of video data. The video data will be coming from a DVI port on a graphics card. My design will be using fpga's to do the image processing. My question is: how do I handle or implement the Extended display identification data when using DVI? I know that I can get DVI receivers but I'm not familiar how to handle the EDID? Basically the graphics card will think its connecting to a monitor so it will expeect the EDID from my box. How do I generate the EDID?



Thanks, joe



Hello Joe,

I am not a video guy but couldn't you use EPROM and store the EDID format for your card to read as if it was connected to a flat panel display? I think that is how it is done 'normally.' I2C communication from an EPROM in the monitor which is communicated to the graphics card.
