GENERAL DESCRIPTION
The SAA4979H provides an economic stand-alone
solution for 4 : 2 : 2 field rate upconversion (50 to 100 Hz
or 60 to 120 Hz) including the required field memory
combined with picture improvement features and dynamic
field based noise reduction. The IC contains two digital
input channels to allow field or frame based
picture-in-picture processing. It also offers a feature
expansion port for vector based motion estimation and
compensation ICs such as SAA4991WP or SAA4992H.
