8964ENC/-FS — Instruction Manual 25
Configuration
Noise Reducer Controls
The Noise Reducer feature is standard on the 8964ENC and 8964ENC-FS
modules. This feature allows separate noise reduction control on each
channel output. The use of these controls depends on the amount and type
of noise present on the signal.
The Noise Reducer process can be enabled or disabled.
When noise reduction is enabled, the following controls are available:
• Filter Select– the type of noise filter may be selected on the web page
only. Choice of the noise filter depends on the type of noise present.
• Level – adjust the noise level (amount of noise reduction).
• Threshold – adjust the noise threshold until the noise is reduced but
video distortion is minimal.
Composite Output Adjustments
The composite output on each channel can be adjusted for the following:
• Add Active Video Setup – add setup to active video.
Note This control also enables or disables the VBI Setup control.
• Output Video Gain – adjust the percent of output video gain relative to
1 V p-p.
Timing and Genlock Considerations
This section is provided for information on some important points about
module reference input sync and color frame timing considerations.
Reference Input Sync
The module is locked to the reference input sync. The following reference
input sync considerations should be noted:
• Jitter performance of the module is influenced by the time base jitter of
the reference input sync.
• Reference input sync timing determines the color burst/output timing.
If a sync changeover is used for the sync reference, the timing of both
sync sources must match. This ensures that the output burst phase of
the module does not change and the timing from the 8964ENC remains
consistent if the reference input sync switches.
