6437 VPBE YCC8 Problem

I use two modular of the 6437 core to verify YCC8 video in and out.

the modular of the video out follow the website.

:http://processors.wiki.ti.com/index.php/Talk:How_to_program_VPBE_YCC8_digital_out

Design 720x480 size video out.

the modular of the video in is :

   VPFE_CCDC_SYN_MODE  = 0x00032F04;   
VPFE_CCDC_HD_VD_WID = 0;
VPFE_CCDC_PIX_LINES = 0x0359020D;
VPFE_CCDC_HORZ_INFO = width << 1;  
    VPFE_CCDC_HSIZE_OFF = width << 1 ;   
VPFE_CCDC_VERT_START = 0x00000000;
VPFE_CCDC_VERT_LINES = 480 ;
VPFE_CCDC_SDOFST = 0x00000000;
VPFE_CCDC_SDR_ADDR = video_buffer;
    VPFE_CCDC_REC656IF  = 0x00000000;	//disable REC656 Interface register, Enable FVH error correction.
VPFE_CCDC_CCDCFG = 0x000088C0;
 
the question is why just receive 360x480 image size?
I change the video output  format  become BT-656.
the modular of the video in can get right image.
what's point I miss ?
