Hi arunkupradhan,
the DE2-TV application has been written for NTSC. If you want to update it for PAL you need to initialize the Analog Devices video codec for the PAL format. You will also have to update the verilog description for the screen size and 50Hz rate.
In contrary to the DE2-TV design, you will not directly be able to change the frame rate to 50Hz for both the video camera and the VGA screen.
Your VGA controller will probably have to work at 60Hz (or higher).
