Use the
Factory Def
control to reset all of the parameters to their factory defaults. The
Serial Number
value refers to that specific FS1 or XD1 module. For information on the
PAL-M Standard
parameter, see
Composite Decoder (on page 38).
Preset
The FS1 and XD1 are capable of saving eight presets. The
Save Preset
parameter saves the current
settings to the selected preset. The read-only
Last Saved Preset
displays the most recently saved preset.
Apply Preset
will apply the settings of the selected preset to the module.
Last Loaded Preset
displays
the preset currently applied to the module.
Version
This section includes FPGA, hardware, software, and advanced audio processing version numbers.
Parameter Control Script
To use a
Parameter Control Script,
select
Enable
in the
Activate Script
parameter. Then create your
content in
Script (Part I)
to change a parameter value based on some other parameters' value. If there is
additional script necessary, use the
Script (Part II to IV)
parameters.
Script Status
[RO] reports the parsing and active status of your custom input script.
The FS1 and XD1 make it possible for you to write user scripts for custom signal flow management, so
that you can dynamically change selected parameters when a signal flow changes. This addresses the
need for managing input video and audio signals that constantly change. In a typical scenario, a preset is
recalled by an operator, or the operator determines what is at the input and then sets up the device to
process the video and audio essence, data and metadata. This is known as "user-scripted signal flow
management" or a " rules engine."
Control Script Example
Some broadcasters have compliance issues that need to be addressed by specialized signal processing.
A common problem is the replacement of a mono audio channel dedicated to audio content for the
visually-impaired, if the channel is absent. Service for the visually-impaired is required in Canada, and
available soon in the United States and elsewhere. In Europe, this service is known as the Audio
Description. In North America, it is known as Descriptive Video, DVS Descriptive Video Service, or Video
Description.
When this mono audio channel is present at the input, the requirement is to pass it through to the
output and into the Secondary Audio Program (SAP) channel. However, if the signal is absent, the FS1 or
XD1 module can detect the problem and perform one of the following through scripts:
