Configuration and Adjustments
This is done by a process of de-interlacing the input signal so that the full
vertical detail of the input is retained. On the KAM-XM modules this is
basically accomplished by using an enhanced version of motion compen-
sated de-interlacing which generates a motion vector for every pixel in the
image.
In the process of up conversion, several factors must be addressed and the
following controls are provided on the modules for these considerations:
Format Conversion
The video input to the module and the video output from the module can
be selected as desired. On the Format web page (
Figure 22 on page 45 ), the
currently detected input is reported, the desired format pulldown is avail-
able and the status of the desired conversion format is reported as avail-
able.
The available input/output format combinations are summarized in
Table 2 on page 9 .
Two additional controls are included in format selection described below:
• Source Material – this control is provided to further distinguish the
type of input signal to the module. Two choices are available, Auto or
Video.
When set to Auto, the module will determine if the input material orig-
inated as video or film and adjust the filtering accordingly. In some sit-
uations, such as broadcast applications, where the input material
cannot be as easily interpreted by the module, the user can force the
mode to Video to prevent artifacts from occurring.
• Deinterlace Type – two types of de-interlacing are provided, PixelMo-
tion and Vert Interpolation.
PixelMotion is a combination of motion-adaptive de-interlacing and
diagonal filtering. When using this technique, the image is analyzed to
determine if there is any motion. This information is used to determine
the filter characteristics used to de-interlace.
Vert Interpolation de-interlacing combines the two fields of video to
create a progressive frame regardless of the amount of motion content
in the image.
