This document is an introduction to Philips SAA4994H datasheet, which provides information on the product's features, technical specifications, application scenarios, etc.
The Philips SAA4994H is a completely digital monolithic integrated circuit designed for field and line rate conversion of all global TV standards. It features improved Natural Motion performance and supports upconversion of 1f, film, and video standards up to 292 active input lines per field.
The device can be configured to emulate the SAA4990H as well as the SAA4991WP. Key capabilities include full 8-bit accuracy, improved recursive de-interlacing, motion compensated 3D dynamic noise reduction, and high quality vertical zoom.
