I would like to know if it is possible to use a cheap dedicated PC graphics card to read DVI signals from a source and then use it to interface with a micro-controller (arduino) or other. Or perhaps using some dedicated DVI processing circuit from a hdmi dvd player to interface with the arduino.
At first I thought you wanted to read DVI data with an Arduino. However, the data rates used by DVI make that impossible. (165MHz pixel clock, 3 data links running 10 times that.)
What do you mean by "use a PC card to read DVI signals and interface to a microcontroller"? What is that going to accomplish?
