Description
The ultimate 4K toolkit
The FS4 is a 4-channel 2K/HD/SD or 1-channel 4K/UltraHD picture synchronizer and up-down-cross converter. This flagship picture synchronizer and converter offers incredible versatility with extensive connectivity integrated into a sleek 1U rackmount design for all your 4K/UltraHD and 2K/HD/SD conversion needs. With a wide range of audio and video input/output options, the FS4 can handle the work of four separate 2K/HD/SD systems, or it can combine all its processors and channels together for maximum 4K and UltraHD productivity flexibility.
Single or 4-channel modes in a 1U rack.
The FS4 offers two comprehensive signal conversion and processing modes:
Single-channel mode provides a full range of 4K/UltraHD processing and up-down-cross conversions from 2K, HD to SD.
Four-channel mode offers four channels of simultaneous 2K/HD/SD conversion and frame memory. All this in a sleek 1U chassis for high-density connectivity.
Single channel mode
. Unwavering reliability. Incredible conversion power.
4K/UltraHD performance, image processing, and synchronization are poised to become the next standard, and the FS4 takes you there with extensive video connectivity, including Quad 1.5G, Dual 3G, Quad 3G over 3G-SDI, and 12Gb/6Gb via optional SFP fiber, 12G-SDI BNC, and 12G-SDI LC modules.
In single-channel mode, the FS4 will convert HD or SD signals to 4K/UltraHD and vice versa, with a vast array of audio channels via Fiber, 3G-SDI, AES, and MADI through a 272 x 208 matrix for incredible audio performance.
Four-Channel Mode
Welcome to four-channel mode.
View Architecture
In four-channel mode, the FS4 offers multi-channel conversion with incredibly extensive simultaneous processing for 2K/HD and SD signals. This processing enables region-of-image (ROI) scaling, color correction, proc amp controls, motion-accelerated deinterlacing, and much more.
Multi-channel density reduced to a 1U rack. Space, power, and energy consumption are preserved.
New thinking, new interface.
The new thinking brings a new interface layout, and the FS4’s front panel has been redesigned to simplify and speed up access to its many features. The panel has been designed to provide direct controls in both single-channel and 4-channel modes. In 4-channel mode, the four VIDx buttons below the Channel Select button are illuminated. In single-channel mode, only VID1 is illuminated; VID2 through VID4 are off.
Up, Down, Cross-Conversion:
Moving to 4K is never an instantaneous change. Traditional signals and archive content must be integrated into the 4K environment, while 4K elements must be downscaled for current 2K/HD workflows. Utilizing AJA’s remarkable conversion algorithms, the FS4 enables conversions from SD, HD, or 2K video to 12G, 6G, 3G-SDI, 4K, or Ultra HD, and vice versa. Supported formats include Quadrant (Quarter Division) and 2SI (2 Sample Interleave).
AJA’s hardware conversion technology ensures the highest image quality for your productions. Key conversions include:
4K/UltraHD/2K/HD/SD Up/Down/Cross Conversions
SD/SD Aspect Ratio Conversion
HD/HD (720p/1080i) Cross-Conversion.
All performed using dedicated 10-bit electronics.
Incredible Digital Connectivity:
Video and audio connectivity and bandwidth meet the demands of your projects.
For inputs and outputs, the FS4 uses standard BNC connectivity as well as optional SFP ports to easily integrate into a variety of workflows and installations, from SDI to 12G.
The FS4 features BNC and fiber inputs and outputs that accept 4K/UltraHD/2K/HD/SD resolution signals in single-channel mode. In four-channel mode, the 2K/HD/SD inputs can be routed to multiple destinations without the need for an external signal distributor. A reference input with probe re-out allows the FS4 to be synchronized to the control room reference signal for maximum stability.
Optional 12G/6G BNC and SFP fiber
The optional SFPs for the FS4 include in BNC and fiber the 12G/6G-HD SDI input/output formats allowing SDI signals great flexibility and fiber to run over distances of up to 10 Km and be directly connected to the FS4 without the need for external fiber/SDI conversions.
Optional optical SFPs:
HDBNC-2TX-12G: 12G/6G-SDI Dual Coax HD-BNC Transmitter
HDBNC-2RX-12G: 12G/6G-SDI Dual Coax HD-BNC Receiver

Massive Audio Flexibility:
The advent of 5.1 and 7.1 audio has increased the number of audio channels that need to be managed in production. The MADI standard provides a convenient way to transport a large number of channels over a single cable, simplifying cabling requirements for broadcast, OB vans, and production environments. The FS4 allows for fiber and MADI inputs and outputs. An internal 277 x 208 mono audio matrix allows for 1-to-1 or 1-to-many routing with support for MADI, mixdowns, and all audio from SDI, fiber, and AES sources, delivering an incredible amount of audio processing capability in a single unit.
Closed Caption Conversion:
The FS4 is compatible with closed captioning, allowing complete conversion between 2K/HD/SD and 4K/UltraHD formats, and accepting CEA-608 and CEA-708 standards. The FS4 can preserve closed captioning even during format conversions, thus avoiding the need to re-insert closed captions after conversion.
Active Format :
Content information is automatically inserted to match the converted signal. This means that it is not necessary to insert the format (AFD) after conversion, and devices that decode AFDs will receive the accurate of the received signal.
Remote Configuration and Control:
The FS4 can be remotely controlled over a network, is SNMP compatible, and includes a web server. Multiple units can be connected to an Ethernet network via their integrated 10/100/1000 Mbps network ports, allowing control and configuration of numerous FS units from any web browser on computers connected to the network. Configurations can be saved and sent to multiple units, ensuring consistency and rapid configuration for large installations.
To ensure seamless integration with existing automation systems, the FS4 can take into account external GPIs to trigger numerous functionalities.
