The SAA4998H is a high performance video processor featuring Natural Motion^TM(2), for all global TV standards (PAL, NTSC and SECAM). It is used together with the picture improvement processor SAA4978H and SAA4979H.

The SAA4998H is an advanced version of the SAA4993H. By embedding the field memories it reduces the part count of the realized concept from 4 to 6 parts to only 2 parts and reduces the package size from a QFP160 to a QFP100.

The full FALCONIC SAA4998H mode uses full motion estimation and motion compensation on ^1/4 pixel accuracy to perform

` Frame rate upconversion
` Film mode detection
` Movie judder cancellation
` Dynamic Noise Reduction (DNR)
` Edge Dependent De-Interlacing (EDDI).

The motion compensated de-interlacer is improved with a new patented Edge Dependent De-Interlacing (EDDI) method. This avoids jagged edges of diagonal lines. The better de-interlacer leads to a significant better performance of progressive as well as interlaced output formats.

A 60 Hz progressive output frame rate can be generated for 50 Hz PAL sources to enable the use of 60 Hz LCD or PDP panels in PAL regions.

50 Hz interlaced to 75 Hz interlaced and 60 Hz interlaced to 90 Hz interlaced of SAA4998H can be generated to achieve an increased number of lines and hence a reduction of line visibility for jumbo screens and PTV applications.

The embedded memory SAA4998H can be used to synchronize the main channel and the 2nd channel for PIP and double window applications. SAA4998H avoids to add additional buffer memory devices to the application.

For demonstration purposes a split screen mode to show the Dynamic Noise Reduction (DNR) function, natural motion, and EDDI is available. The estimated motion vectors can be made visible by colour overlay mode.

The SAA4998H supports a Boundary Scan Test (BST) circuit in accordance with "IEEE Std. 1149.1".
