Video / SD Video Source Menu
Table 5.10 describes the SD Video Source menu items that permit the selection of video
source parameters when operating in the Standard Definition video format.
They are listed alphabetically to help with retrieving the information.

Selected Item
Options
Description
25 Hz
Used in 625 lines (most PAL systems except PAL-M).
29.97 Hz
Used in 525 lines (NTSC and PAL-M systems).
Frame Rate:
This option enables the Frame
Rate to be set.
NOTE…
The frame rate is only shown when the video input is Serial Digital, any Test
Pattern or Off.
Ident Text
Up to 20 characters. This is the text that is displayed if the video output is lost (see OP Video Loss
option).
Manual
The frame rate must be set via the Frame rate option.
Auto Frame Rate
The frame rate is automatically detected.
Input Source Select:
This allows the enabling or
disabling of automatic frame rate
detection.
Auto Config Switch
The frame rate is automatically detected, and the Encoder loads the appropriate
configuration defined by Default 525 Config and Default 625 Config.
I/P Monitor Refresh:
Sets the update rate of the input
video monitor on the front panel
and the web browser monitor
Between 1 and 224
updates per minute.
Max Still Period:
Allowed values:
from 0 to 255
seconds.
Off
Noise reduction off
Adaptive 1
Use noise reduction if necessary but don’t introduce artifacts.
Adaptive 2
Medium adaptive noise reduction, best compromise between Adaptive 1 and 3
Adaptive 3
Very powerful adaptive noise reduction, may introduce some filter artifacts but
will remove as much noise as is possible.
Adaptive 4
For turn-around systems where the input video signal includes coding artifacts.
Fixed 1
Weak non-adaptive noise reduction independent of input noise.
Fixed 2
Medium non-adaptive noise reduction independent of input noise.
Fixed 3
Strong non-adaptive noise reduction independent of input noise.
Noise Reduction:
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
that can reduce the encoding
difficulty considerably. Refer to
Application Note ST.AN.1094,
Video Noise Reduction and
Compression
for more information.
Only available when licence key
EN8000/SWO/NR enabled.
The noise reduction module has two stages which are available for each frame:
Estimation of the level and type of noise in the frame; and
Application of the noise reduction filter at one of four levels of noise reduction capability dependent on
the results of the estimation stage.
The operator has a choice of four settings for the estimation (called Automatic) to be selected or for the
estimation stage to be ignored and one of the fixed levels to be used independent of the noise level
(called Manual).
