video capturing in ADSP-BF533 using PPI

 
Dear friends,

i'm using video input program given by ADI. Output is YCbCr format.it stores the data in SDRAM from oxo memory location. x count is 50000. x modify is 4.

my camera specification is NTSC, 512x492, color, 30frames/sec...

For this specification what are the changes i have to do with this example code?
can i see the real time video using image viewr from this code? if yes how can we calculate the video bytes?
how can we extratct the frames ie., in what order datas are storing in the SDRAM?

please help me .thanks in advance.
