As sports fans have come to expect a more dynamic, interactive experience, augmented reality (AR) is quickly becoming a common and valuable production asset, but one that requires additional video processing time.  For seamless integration of AR into live productions, larger frame buffering capacities are required to delay other sources. 

FS4 offers the largest configurable frame delay in its class of up to 20 frames per channel, ensuring all sources stay in time.

Video and Audio deserve the connectivity and bandwidth required to meet the demands of your projects.

FS4 utilizes standard BNC as well as optional SFP inputs and outputs to integrate easily into a variety of workflows and facilities with support for SDI workflows all the way up to 12G.  

FS4 has Coax and Fiber* inputs and outputs to accept 4K/UltraHD/2K/HD/SD resolution signals in Single Channel Mode. In Four Channel Mode 2K/HD/SD inputs can be routed to multiple locations simultaneously without the need for any external signal distribution.

A looping Reference Input allows the FS4 to be locked to your house reference signal for rock solid stability.

Digital Audio can be disembedded and embedded between SDI, MADI, and AES for an incredible array of routing possibilities.

* SFP  inputs and outputs are optional.

Moving to 4K is never an instant change. Legacy signals and archival material need to be integrated into the 4K environment, while 4K/UltraHD sources need to be down-converted for current 2K/HD pipelines.

Utilizing AJA's remarkable conversion algorithms, FS4 supports up, down, cross-conversion from 2K/HD/SD to 4K or UltraHD.  Both Square Division (SQD) and Two Sample Interleave (2SI) pixel mapping formats are supported.

AJA's powerful hardware conversion technology ensures the highest image quality for your productions. Key conversion features include:

• 4K/UltraHD/2K/HD/SD up, down-conversion
• SD/SD aspect ratio conversion
• HD/HD cross-conversion (720p/1080i)

All done in beautiful 10-bit with dedicated hardware.

FS4's SFP options include both 12G/6G-SDI HD-BNC and LC Fiber I/O options, including single and dual channel Single Mode options and Multi-Mode options, allowing great SDI flexibility and fiber cable runs of up to 10 kilometers to be connected directly to the FS4 without the need for separate fiber to SDI conversion. Also available are 3G-SDI Fiber LC and SC SFP options.

Optional 12G/6G-SDI SFPs:

• HDBNC-2TX-12G:  12G/6G-SDI Dual Coax HD-BNC Transmitter

SKAARHOJ’s line of hardware based control panels provide integrated control of AJA’s FS family of frame synchronizers. The new Rack Control Duo, developed in partnership with broadcast services provider NEP, supports AJA’s FS-HDR, FS4, FS2, and FS1 devices and is capable of ganging control of multiple FS products and processing channels together, making set-up and on-the-fly adjustments faster and easier for operators and engineers with a single tactile hardware control panel. Ideal for any production environment involving multiple source signals, Rack Control Duo is an intuitive hardware control panel with tactile knobs and buttons to easily perform simultaneous adjustments across multiple AJA frame synchronizers. Operators can also use the panel to recall, and implement presets from previous setups across one or more FS devices. When used in conjunction with FS-HDR real time HDR/WCG converters, RGB color corrections can be performed via Rack Control Duo prior to HDR to SDR or SDR to HDR transforms, harnessing the power of AJA’s FS-HDR.

The growth of 5.1 and 7.1 audio has increased the number of audio channels that must be managed in production. The MADI standard provides a convenient way to transport huge numbers of audio channels along a single cable, simplifying the cabling demands for broadcasters, mobile trucks, and production. FS4 supports both fiber and coax MADI input and output.  An internal 277 x 208 mono audio matrix allows you to route 1 to 1, or 1 to many, with full routing of MADI, mixdowns, and all audio coming from SDI, fiber, and AES sources for an incredible amount of audio processing capability in a single box.

FS4 also offers high quality Sample Rate Conversion (SRC) on all audio inputs, which can be bypassed for non-PCM audio.

FS4 is network ready and supports SNMP monitoring and web-based remote control. Units can be connected to an Ethernet network via the built-in 10/100/1000MB Ethernet port, allowing control and configuration of multiple FS units from a web browser on a connected computer. Configurations can be saved and applied to multiple units, ensuring consistency and quick configuration in large installs.

To integrate smoothly with the existing automation of a facility, FS4 can also receive external GPI commands to trigger a variety of functions.

AJA’s technical support is recognized as among the best in the industry and is available to all AJA customers. If you need assistance with any aspect of your FS installation, configuration, operation or encounter any technical issue,   will work with you to get up and running.

FS products are covered by a generous five year warranty. Please see the individual Product’s Manual for additional specifics around warranty conditions for the product itself.

Eliminate extra interface clutter and menu bars and extract only the portion of the computer screen you want.

Connecting a ROI Mini-Converter via USB to a computer running the free Mini-Config application lets you interactively select a Region of Interest from the incoming computer signal and have full control over how that region is scaled to the output resolution using AJA’s high quality scaling algorithms for the cleanest picture quality possible. 

Watch this video to learn how to configure and control your ROI with AJA's free Mini-Config control software.

Take full control of aspect ratio and frame rate conversion with on-screen controls in the Mini-Config software that show you exactly what your source and output will look like and what formats are coming in and going out. Simple menu controls let you quickly choose the proper output for any situation.

ROI utilizes a direct loop through, allowing it to be placed in-line so you still have a connection to an external monitor while extracting to SDI. The reference input ensures the SDI signal out of ROI is locked for use throughout a production or facility.

ROI accepts 2-channel audio from the 3.5mm analog audio input or embedded 8-channel audio from an HDMI input. The audio source and routing can be selected in the Mini-Config software and is embedded in the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.
