Nios II 3c120 uP with LCD Controller - Getting Started

Hi,

I downloaded this example processor system from http://www.altera.com/support/examples/nios2/exm-nios-lcd-3c120.html.

As a beginner, I have the following questions:

Can I directly use this design by programming the FPGA with the existing .sof file? or should I recompile the design and then use the new .sof file?

I want to input a video (either composite or DVI) and then see whether it is displayed on the provided LCD. Should I write code for this or it is already included?

Thank you.
