Title: Method and apparatus for detecting chroma field motion in a video signal

Abstract: A method and apparatus for blending a video signal responsive to a chroma motion result is disclosed. The method and apparatus are configured to determine whether any chroma motion exists within the video signal and providing the chroma motion result, to provide a first blending signal based on the chroma motion result; to provide a second blending signal based on the chroma motion result; to modulate temporal filtered luma and chroma components of the video signal with the first blending signal, to modulate spatial filtered luma and chroma components of the video signal with the second blending signal, and to add the modulated temporal luma and chroma signals to the modulated spatial luma and chroma signals to provide a blended video signal.
