how to change NTSC to PAL

In DE2_TV project,the design converts DVD video into a format suitable for display on a CRT/LCD monitor.Now I want to use the CCD camera to connect to the VIDEO IN port on the DE2 board.I think the DVD signal is NTSC format and the CCD camera is PAL(not ensure).I try to modify the register value in I2C_AV_Config.v,but not success.

SET_VIDEO+0:LUT_DATA<=16'h1500
