FPGA for Video and Audio Processing

Thanks a lot dear Socrates for your help.

Then check out Cyclone III Video devkit. I have this one, but Altera made a huge mistake in such devboard by adding a level converter on HSMC connectors for clock wire, which is only capable of 100MHz max. Now I can't connect any of mine HSMC boards: either with 1gbit ethernet (clk=125MHz) or DVB-ASI board (clk=135MHz)... Huge FPGA with no possibilities to add any fast boards.

Thanks a lot, but for me this devkit is too expansive :)

I would suggest Stratix IV Video devkit.
