I have and ADV7180 decoder chip. Also I have two CVBS sources one coming from a unipolar DAC
and another coming from a bipolar DAC.
I observed that the luma component when the CVBS signal from coming from bipolar DAC is given to the
decoder is double of that received when CVBS signals from unipolar DAC is given to the decoder
Does the decoder differentiate between the two CVBS sources? Is there any specific decoder setting that
needs to be done when the CVBS signal from a unipolar DAC is given to the decoder.
