The SDA 9400 is a new component of the Micronas MEGAVISION® IC set in a 0.35 µm 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)SDA 9400 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 of SDA 9400 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 of SDA 9400 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 of SDA 9400 can be compressed horizontally and vertically with a certain number of factors. Therefore split screen is supported.

Beside these additional functions of SDA 9400 like coloured background, windowing and flashing are implemented.
