ADV7403 STANAG Colour Issue.

Hi,

I have the following requirements for ADV7403:

I/P Video - STANAG 3350 with Sync On Green as Input to the Chip.

1)720x576i @ 50/25Hz(Class B)video resolution, Interlaced video input,RGB(STANAG Class B)
2)720x480i @ 60/30Hz(Class C)video resolution, Interlaced video input,RGB(STANAG Class C)

O/P Video - 8bit YCbCr 4:2:2, BT656 Format as output from the chip.

Hardware Connections:
We have custom hardware with ADV7403 chip whose input channel configuration for RGsB is given below

Ain1 - G and SOG
Ain2 - B
Ain3 - R

I have attached the scripts and corresponding Pictures of the output I have observed with the scripts.

Image 1 is the actual test pattern and Images 2-5 are the output observed with the scripts 2-5 respectively.

Image 2, obtained by script 2, has no color but we can observe different bars and Image 3 has only black and white bars .

In Image 4 there is more Yellow component, so the white bar is yellowish and all other bars have more yellow components and in Image 5 there is a color swap between yellow and blue bars and red and blue color bars.

I wanted to know how can I solve this issue using the script.

Please go through those scripts and let me know anything to be added or modified to those scripts.
