HI, all
I am using TVP5150A connecting with a PAL camera as input, and connect to DM642.The TVP5150 output is a standard ITU-R 8bit BT656 4:2:2 (720*576) with embedded synchronization(SAV and EAV).The DM642 is used to process the BT656 data.ALL function is OK .However the output video has a black area in the rightest place.
To find the reason,I want to see weather the BT.656 data output from the tvp5150 is right.I use the CCS to display the picture (Y,Cb,Cr Data is directly picked up by DM642 from the TVP5150 8 bit BT.656).The problem is the same as before.That is,a picture (720*576)is completely right,but in every line(576),from the 704 pix to the 720 pix is black.So I think the problem is the tvp5150
I try to chang the AVID and the VBLK,but there is no use.
The TVP5150 is configed like this:
Uint8 vFromat = 0;
Uint8 misc_ctrl = 0x6D;
Uint8 output_format = 0x47;
Uint8 input_sel = 0x00;
Uint8 pin_cfg = 0x02;
Uint8 chro_ctrl_2 = 0x14;
_IIC_write(hI2C, addrI2C,0x00, &input_sel,1);
_IIC_write(hI2C, addrI2C,0x03, &misc_ctrl,1);
_IIC_write(hI2C, addrI2C,0x0D, &output_format,1);
_IIC_write(hI2C, addrI2C,0x0F, &pin_cfg,1);
_IIC_write(hI2C, addrI2C,0x1B, &chro_ctrl_2,1);
other regsers are default .
Who can give me some hints? Thanks you very much!
