Selenio X100
Installation and Operation Manual
Linear FRC (Frame Rate Conversion)
This feature is an optional high-quality frame rate converter that supplements the X100's
basic automatic FRC. To use Linear FRC, the X100OPT-SK-SC softkey option must be
purchased.
When the X100 is in Linear FRC, it is reduced to single path functionality; channel 2
processing is disabled. (A block diagram with a single processing channel will appear in the
user interface.) During this time, the same frame rate video can continue to pass through.
The following video formats are supported in Linear FRC mode for inputs and outputs:
59Hz: 525, 720p59, 1080p29, 1080i59, 1080p59, 1080p59DL
50Hz: 625, 720p50, 1080p25, 1080i50, 1080p50, 1080p50DL
60Hz: 720p60, 1080p30, 1080i60, 1080p60, 1080p60DL
Note: To activate Linear Frame Rate Conversion, the X100 must be rebooted.
Audio/Video Delay in Linear FRC Mode
When the input and output frame rates are different, the audio and video delay cannot be
perfectly matched to achieve proper lip sync. However, because of the nature of FRC, there
are worst-case boundaries for the audio/video delay. The worst-case audio delays relative to
the video are the following:
5 ms of leading audio
15 ms of lagging audio
These worst-case boundaries cover all of the supported video format conversions.
Profanity (Program) Delay
The Profanity or program Delay feature requires the installation of an optional
X100OPT-MEMMOD8GB or X100OPT-MEMMOD16GB memory submodule, in addition to
an optional X100OPT-SK-PD software key. (Installation instructions for the memory modules
are found on page 162) In dual-channel applications, two softkeys are required. The two
processing channels are able to operate delay modes independently.
Both the program delay and the logo generator inserter can be used at the same time.
However, the 16 GB memory makes it possible to use longer animated logos. See
for details.
The Selenio X100 Delays Table (a separate document available on our website) shows the
software keys and memory submodule required for each configuration. In addition, the
table lists the maximum program delay, and the animated logo duration available per
channel, in each configuration.
Other operations that use the program delay feature include Individual Channel Delay
Mode and Local-to-Remote Timing.
Profanity Delay Mode
Using the Profanity Delay Mode, a "non-delayed" version of the program signal is sent to
the master control operator who has the option to "bail-out" and select a backup signal to
take to air, if a program signal contains profane images or audio
