The SAA4998H is a high performance video processor
featuring Natural Motion
(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 mode uses full motion estimation and
motion compensation on
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 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 can be used to synchronize the
main channel and the 2nd channel for PIP and double
window applications. This 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” .
