The SAA4979H is a sample rate converter with embedded high quality dynamic noise reduction and expansion port produced by Philips Semiconductors.
The Philips SAA4979H is a stand-alone solution designed for 4:2:2 field rate upconversion (50 to 100 Hz or 60 to 120 Hz). It combines required field memory 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.
