Decoding DVI-D signal

Hello

I want to launch a proposal to all users and admins of the forum :
" Decoding DVI-D signal " - it is possible to achieve this using flowcode?
- what type of microcontroller must be used

Personally I want to build a interface that takes the DVI-D signal and outputs on multiple DMX512 Universes.

If anyone with some knowledge and solutions want to take part of this project, please reply.

Thank you

Hello

Not too sure on the Specs for DVI-D but im guessing that a PIC is not going to be enough. An ARM might be fast enough able to keep up with the signals. Other then this you are into FPGA territory which is not covered by Flowcode.

Hello Benj

I was thinking of another approach , after I checked some documentations.
Maybe it is wise to use at the first signal decoding layer a specialized DVI receiver like TFP403 ( 401, 402 ) Texas Instruments
http://www.datasheetcatalog.org/datashe ... tfp403.pdf

after that take the decoded signal from the TFP receiver and start collecting data pixels. Here we must make a valid synchronization with the signal data, i guess using VSYNC and HSYNC; also DE seems to be useful - tells the difference between Signal with DATA PIXELS and Signal with DATA COMMAND. Then is it is very easy to update a different PIC micro for each universe, that send DMX512 data using the EUSART .

I made a little diagram to understand better what I mean.
