Introduction
®
The SDA 9410 is a new component of the Micronas MEGAVISION
IC set, which
enables the system to reduce large area and line flickering of interlaced TV standards.
The scan rate conversion to 100/120 Hz interlaced or 50/60 Hz progressive scan is
motion vector based. For the 100/120 Hz (50/60 Hz) conversion the SDA 9410 really
calculates 100/120 Hz (50/60 Hz) fields with continuous motion phases to avoid double
contour effects in the motion display. In the special case of movie sources, which have
a non-continuous motion phase, the SDA 9410 generates at the output an appropriate
sequence with a continuous motion phase („True Motion“).
Due to the frame based signal processing, the noise reduction has been greatly
improved. Furthermore different 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 SDA 9410 has two input channels, which can be used for different features like
Picture-in-Picture (maximum approximately 1/9 picture) and “Double-window/Split-
screen”. The two input signals can be scaled horizontally and vertically with variable
factors. Panorama modes will be supported.
Besides that an algorithm for the detection of letter box pictures is included. The SDA
9410 delivers the start and the end line of the active picture part of the input signal to an
external µC. The µC calculates the zoom factors for displaying the active picture part on
the full screen and sends this values back to the SDA 9410.
Picture sharpness can be greatly improved by a LTI (luminance transition improvement)
or/and peaking and a CTI (colour transition improvement) algorithm. The resolution of
the output signals is 9 bit. The SDA 9410 has analog output signals.
