Noise Reduction Option

3

This option enables the noise reduction feature to be switched on (at

different levels) or off. The feature can be used when the incoming picture

material is corrupted by high frequency noise (such as white noise). When

noise reduction is enabled, the Encoder applies sophisticated edge

preserving filters on the incoming material and removes the noise which

can reduce the encoding difficulty considerably.
To access the Noise Reduction option, press the Noise Reduction softkey

from the Video Source Menu.
The three levels of noise reduction are in increasing order of noise

reduction capability. They are independent of video content. All three

settings are noise-level adaptive, i.e. it is not necessary to change the

setting for different noise levels.
Once a level has been selected it can be left enabled. When a clean source

is used the noise reduction dynamically switches off and then back on

when noise is present. Refer to Application Note ST.AN.1094, Video Noise

Reduction and Compression for more information.

Noise reduction is only available when software option M2/ESO2/NR is purchased.
