FS3 Frame Synchronizer/Converter v1.1r1 10 www.aja.com
Video Processor
The Video Processor performs format conversion, frame synchronization, signal
processing, and keying operations. Conversion is done with very high quality
scalers. De-interlacing is performed with high quality motion-adaptive processing
including diagonal filters. The Processing Amplifier and Color Corrector supports
video signal adjustment with standard Proc Amp controls and RGB color
correction.
Audio Processor
The FS3 can accept and route any embedded audio input to the logical SDI1 thru
SDI4 outputs. Audio on SDI1 thru SDI4 outputs is duplicated on SDI5 thru SDI8
and Fiber1 thru Fiber4 outputs.
Channel mapping allows different individual audio input channels to be routed to
different individual logical outputs. Any embedded audio input can be routed to
any embedded audio logical output using channel mapping.
An internal mixer is available that permits mixing down five inputs (5.1) or seven
inputs (7.1) to a left/right stereo mix.
FS3 does not perform digital audio sample rate conversion. The Dolby 5.1 and
similar schemes of digital encoded audio are passed unaltered, provided the
input is genlocked to the FS3 output.
About Embedded Audio Routing
The FS3 can disembed a set of 16 channels (8 pairs) of embedded digital audio
from each SDI input. Each set of audio channels are embedded into each logical
SDI1-SDI4 portion (SDIn) of the SDI signal.
When not using the FS3 channel mapping feature, each set of 16 audio channels
are routed together, from one SDIn source to one SDIn destination. Exactly which
FS3 physical output connector carries which set of embedded audio can vary,
depending on the FS3 configuration.
Operation Overview
About Inputs and Outputs
In general, to use the FS3 for video up-conversion, first select an Output Video
Format (with the VIDEO PROC, Video Output Format Menu) that is compatible
with the current FS3 genlock source (see below), then select an Input port (with
the VIDEO PROC, Input menu). The FS3 will automatically determine the selected
input video format and convert it to the selected Output Video Format. The
converted video is routed to the FS3 output ports, duplicating the signal on all
complete sets of available connectors.
About Reference and Genlock Source
A genlock source being used by the FS3 for reference must be compatible with
the FS3 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 60/24).
The FS3 can be configured to operate with one of a variety of references,
including genlock to the signal from the Reference input connector, genlock to
the current video input signal, or Free Run. Your choice of reference needs to
