Chapter 1 – Introduction
Overview
The new FS3 combines AJA’s industry-proven frame synchronization with
high-quality 4K up-conversion technology to seamlessly integrate SD and HD
signals into 4K workflows. AJA’s adaptive scaling algorithms, paired with our
well-known conversion technology ensures your up-converted images will have
the maximum quality possible. You can input SD or HD resolution SDI via BNC
or Fiber, and output up-converted 4K video to multiple BNC and Fiber outputs
simultaneously. FS3 also includes the industry-proven features included in AJA
frame synchronizers such as up, down, cross-conversion of SD, HD, and 3G-SDI
formats, RGB color correction, region of interest scaling, extensive audio controls
and routing, web UI control, GPI triggers and more, making it an extremely
versatile tool that can support a variety of production requirements.
Synchronizing diverse formats is a critical part of a broadcast, mobile or post-
production environment. FS3 syncs to analog SD blackburst, HD tri-level sync, or
to the incoming SDI signal. FS3 also provides integer frame rate conversion (3:2,
1:2, 2:1).
The growth of 5.1 and 7.1 audio has increased the number of audio channels that
must be managed in a production. FS3 accepts embedded SDI audio on all four
SDI inputs (two coax and two optional fiber), and has an internal 64x64 audio
matrix that allows routing of all embedded audio channels. Besides audio level,
phase, and delay controls, FS3 also provides for 5.1 or 7.1 mixdown to stereo.
Video Features
• Video format converter, that accepts SD, HD or 3G SDI video and up-converts
the signal to UltraHD (3840x2160) or 4K (4096x2160), and also up/down/cross
converts SD, HD, and 3G-SDI.
• The FS3 handles a wide variety of video output formats, including 4K/UltraHD
Quadrant (Square Division) and Two Sample Interleave (2SI). See
for a complete list.
• Multiple mirrored outputs: three for Quad SDI, six for Dual SDI, and twelve for
Single SDI.
