Real Time HDR/WCG Conversion with the Colorfront 
Engine™ Video Processing
	AJA 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.
  AJA 
	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.
  
	Up, Down, Cross-Conversion
	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, AJA 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. 
	 12G/6G HD-BNC and Fiber SFP Options
	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. 
	 Massive Audio Flexibility
	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.
  
	Closed Captioning Conversion
	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. 
	 Active Format Description
	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. 
	 Remote Configuration and Control
	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.
