FS4 Frame Synchronizer/Converter v1.1
The FS4 can embed 16 channels of audio from any of the audio inputs to each complete
video output. On multiple link outputs, the audio is embedded on the first link. When
signals are duplicated on multiple outputs, the same embedded audio is present on the
first link of all the duplicated outputs.
Audio Processor
The Audio Processor accepts AES, MADI and embedded SDI audio and performs high
quality sample rate conversions as required. Full audio channel mapping supports any
mixture of inputs to outputs.
Dolby 5.1 and similar schemes of non-PCM digital encoded audio can be passed
unaltered, provided the input is genlocked to the FS4 output.
Internal mixers are available that permit mixing down five inputs (5.1) or seven inputs
(7.1) to a left/right stereo mix. Two Mixdown mixers are available in Four Channel Mode,
and one Mixdown mixer is available in Single Channel Mode.
Optional FS4 Features
SFP I/O
All FS4's SFP I/O ports support up to 3G SDI data rates. In addition, in Single Channel
mode the FS4‘s SFP ports 5 through 8 In and Out also support 12G and 6G SDI, when
equipped with a compatible SFP module.
The FS4 supports optional AJA Optical SFP I/O modules as follows:
• Single Input, LC connector (up to 3G)
• Single Input SC connector (up to 3G)
• Single Output LC connector (up to 3G)
• Single Output SC connector (up to 3G)
• Dual Input LC connectors (up to 12G)
• Dual Output LC connectors (up to 12G)
• Dual CWDM
• Dual HD-BNC connector (up to 3G)
• Dual Output HD-BNC connector (up to 3G)
Only AJA SFP modules are supported; use of other manufacturers' modules is not
supported and may void the warranty.
Operation Overview
About Inputs and
Outputs
In general, to use the FS4 for video conversion, select a Video Processor Channel, select
an Output Format that is compatible with the current FS4 reference signal (see
below), and then select an Input port. The FS4 will
automatically determine the selected input video format and convert it to the selected
Output Video Format. The converted video is routed to the FS4 output ports.
About Reference
and Genlock Source
A source being used by the FS4 for reference must be compatible with the FS4 video
output format. These signals are compatible when they are both in the same frame rate
family (59.94/29.97/23.98, or 50/25, or 60/30/24).
