Adaptive Y/C: Detect changes in the luminance and chrominance
components of the video signal separately, and switch automatically
between fields and frames.
Adaptive Y: Detect changes in the luminance component of the video
signal separately, and switch automatically between fields and frames.
Field: Do interpolation in field units. This gives natural movement,
suitable for moving video.
Frame: Do interpolation in frame units. This gives higher image precision,
suitable for still pictures.
