Motion Adaptive De-Interlacing. Motion adaptive de-interlacing is a pixel-based two-phase
process. Phase 1 involves the detection of motion and the generation of a motion value for
each pixel. These pixel motion values are used as a measure of the current "degree of
motion". In Phase 2, the pixel motion values are used to select the appropriate de-interlacing
technique. As a result, areas of an image that are not moving will be fully static (flicker free)
and moving objects will have smooth edges.
Set to either "Normal", "Adaptive" or "OFF".

The media noise reduction block removes unwanted ringing and block noise from images
that have undergone MPEG or JPEG compression and decompression. The two types of
media noise that can be reduced are:

• Block Noise: MPEG encoders, in the presence of an almost flat area, can create a
squared structure due to the discrete 8x8 squares that are used in the MPEG
compression process. This creates a noticeable squared structure in the image.
The process smoothens these square boundaries so they are not visible. The
amount of smoothening is programmable between neighboring pixel values that will
be smoothened. The amount of smoothening starts to decrease linearly from the
maximum (defined by TO) to 0 (defined by 2 x TO) to avoid the hard switch effect of
the smoothening applied.
• Mosquito Noise: This process smoothenes checker box and discrete noise artifacts
referred to as Mosquito Noise around large edge transitions caused by MPEG
encoders.

Dynamic NR (Noise Reduction) Mode can be set to either "High", "Medium", "Low",
"Adaptive" or "OFF". This is the "strength" of how much noise to detect and
automatically remove in order to enhance the overall image quality. The Block Noise
process will be used.
