Hi faddiUOA,
1. For display the image or video from camera or video player, just plug the video cable at TV decoder input and load the program to the board. If u need to change the code, make sure for ur application only. The original program only display the image data connect trough TV decoder on the board. Read the manual for the specification. The input must NTSC format, for PAL u can email me at

As for the TV demo code, the clock signal is synchronize from TV decoder. For NIOS??? I don't know. Sorry. In my opinion, u can used verilog hdl like the original code.
