heloo friends,
My requirement is I need to connect the DVI signal as input to the FPGA, and inside FPGA I have to convert this DVI vedio signal into LVDS and send the data to the display. Now I have one question in mind whether I can directly connect the DVI vedio signal to FPGA??
If it is possible to connect and then what steps are required to convert from DVI to LVDS. As I have seen some display development kit details from xilinx : http://www.xilinx.com/support/documentat...es/xapp928.pdf. which shows the block diagram where the DVI interface recieves the DVI input and then it is passed to colour temperature correction(CTC) block then the output of CTC is given to Precise gama correction(PGC) block then the output of PGC is given to image dithering engine(IDE) block then it is passed to LVDS interface block where this block provides LVDS output.
Here my doubt is whether is it necessary to do the processes like CTC, PGC and IDE to convert the DVI signal into LVDS. As per my understanding DVI(TMDS) and LVDS are both serial differential signals which are similar. Now another question is,
1. "Is it possible to do DVI to LVDS conversion inside FPGA??"
2. "By converting DVI signal to LVDS signal whether the information or quality of the signal will be affected??"
Can anyone please suggest me which is the best website to understand DVI, LVDS and conversion between both.And also any development kits or refference available for converting DVI to LVDS.

Thanks.
