18: CVBS and RGB colour adjustment
Purpose
Adjust the colour saturation in the CVBS picture so it matches the RGB picture.
This is not a factory adjustment.
The adjustment applies only to the specific source connected to the specific input,
such as a DVD 1 connected to the AV input.
The scart input must have an RGB input, this is V.TAPE or AV input.
How to decide whether or not to adjust.
Use the external source as PIP picture and compare against TV picture.
Adjustment may be performed if there is a difference in the colour saturation
between the main picture and the PIP picture.
The decision is made by the customer.
The adjusted values are stored in the EEPROM.
