Preliminary Data Sheet

General description
The SDA 9400 is a new component of the Micronas MEGAVISION
IC set in a 0.35 m embedded
DRAM technology (frame memory embedded). The SDA 9400 is pin compatible to the SDA 9401
(field memory embedded). The SDA 9400 comprises all main functionalities of a digital featurebox
in one monolithic IC.
The scan rate conversion to 100/120 Hz interlaced (50/60 Hz progressive) is based on a motion
adaptive algorithm. The scan rate converted picture can be vertically expanded. The SDA 9400 has
a freerunning mode, therefore features like scan rate conversion to e.g. 70, 75 Hz with joint lines or
multiple picture display (e.g. tuner scan) are possible.
Due to the frame based signal processing, the noise reduction has been greatly improved.
Furthermore separate motion detectors for luminance and chrominance have been implemented.
For automatic controlling of the noise reduction parameters a noise measurement algorithm is
included, which measures the noise level in the picture or in the blanking period. In addition a spatial
noise reduction is implemented, which reduces the noise even in the case of motion. The input
signal can be compressed horizontally and vertically with a certain number of factors. Therefore split
screen is supported.
Beside these additional functions like coloured background, windowing and flashing are
implemented.
