FS4 is a 4-channel 2K/HD/SD or 1-channel 4K/UltraHD frame synchronizer and up, down, cross-converter, and so much more. This combination frame synchronizer and converter offers incredible versatility and connectivity in a sleek 1RU frame for all your 4K/UltraHD and 2K/HD/SD conversion needs. FS4 offers a wide range of connectivity for both video and audio, including optional SFPs for single link 12G-SDI connectivity. For HDR workflows, the FS4 supports automatic or configurable HDR metadata generation for the SDI output VPID and HDMI output HDR Infoframe.
In Four Channel Mode, FS4 can do the work of four separate devices in 2K/HD/SD or combine all processors and channels for maximum flexibility for 4K/UltraHD productivity in Single Channel Mode.
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.
Different Modes for Different Needs
FS4 offers various modes of operation for comprehensive conversion and signal processing.
Single Channel Mode provides a full suite of 4K/UltraHD processing and up, down, cross-conversion to and from 2K, HD, or SD.
Enhanced Single Channel Mode provides simultaneous 4K/UltraHD and 2K/HD outputs where the 2K/HD monitor output can have its own unique down-conversion applied.
Four Channel Mode offers 4x 2K/HD/SD channels of simultaneous conversion and processing, all within an elegant 1RU chassis for multi-channel high density delivery.
4K/UltraHD Conversion Power with simultaneous 2K/HD outputs.
FS4 is your real world answer for conversions to and from multiple resolutions, built to AJA’s high quality and reliability standards.
4K/UltraHD delivery, processing, and synchronization is fast becoming the next standard, and FS4 gets you there with a wealth of digital video connectivity, including Quad 1.5G, Dual 3G, Quad 3G over 3G-SDI, and 12G/6G over optional 12G-SDI BNC and 12G-SDI LC Fiber SFP modules.
In Single Channel Mode, FS4 will up-convert your HD or SD materials to 4K/UltraHD or down-convert your 4K/UltraHD to HD and supports a huge array of audio channels over Embedded SDI, AES, and MADI for an incredible 272x208 matrix of audio processing capabilities.
Enhanced Single Channel Mode offers simultaneous 4K/UltraHD and 2K/HD outputs. In this Mode, frame synchronization and processing can be performed on true 4K or UltraHD signals, and a configurable down-converter is available for HD or SD needs via the SDI monitor output.
Multi Channel HD Processing.
In Four Channel Mode, FS4 provides incredibly powerful multi-channel conversion with up to four channels of simultaneous processing for 2K/HD and SD signals. Powerful conversion processing also allows Region of Interest (ROI) scaling, color correction, proc amp controls, motion adaptive deinterlacing, and much more.
In Four Channel Mode, you can also bring in a single HD source and process four separate outputs from it, each with its own conversion applied.
Multi-channel density in a 1RU chassis - space, energy, and power preserved.
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:
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:
Optional 3G-SDI Single Mode SFPs:
Optional 3G-SDI Multi-Mode SFPs:
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 supports Closed Captioning and the conversion of Closed Captioning between 2K/HD/SD and 4K/UltraHD formats - including full conversion of CEA-608 and CEA-708 standards. FS4 can preserve Closed Captioning even when converting between formats, removing the need to reinsert Closed Captioning after conversion.
Automatically sets Active Format Description information to match the converted signal. This means AFD information does not have to be inserted after conversion and provides accurate information for devices that understand AFD.
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, AJA Support will work with you to get up and running.
