Capturing the image from an NTSC Camera and displaying it live on a VGA monitor

I need Verilog code for capturing images from NTSC camera (input is video camera), buffering images in external RAM on Nexys2 labkit (FPGA Spartan 3E XC3S500E FG320), and using the VDEC1 ADV7183B video decoder chip to convert from NTSC to YCrCb, then displaying the images on VGA monitor. Basically, the input to the VDEC1 will be NTSC, the output of this chip will be YCrCb, Then, the YCrCb should be converted to RGB to be buffered and displayed on the vga monitor. Attached is pdf of a very close project, but I need the output to be VGA (640 by 480) not SVGA. And definitions of the modules in verilog are povided in the zip file.
