Um, thanks, but I think I am still in the dark. Once again, the question is why moving the whole luma band to the right, if its width is not changed? What does it improve? Similarly, does moving chroma carrier to the right improve color resolution if the width is the same? Unless the luma was moved to the right to free more bandwidth for chroma and to reduce the interference with hi-fi audio? Could you explain to someone who understand algebra and calculus, but is not a radio engineer?
