April 9, 2018

Las Vegas, NV, NAB Conference, Stand SL2505 (April 9, 2018)—AJA Video Systems has announced v2.5 firmware with new feature enhancements for the company’s FS-HDR real time High Dynamic Range (HDR) and Wide Color Gamut (WCG) converter/frame synchronizer with Colorfront Engine™ video processing. The company also released new single and multi-mode fiber SFP options for FS-HDR and FS4.  

v2.5 firmware enhances the Colorfront Engine transform algorithm with support for ITU BT.2408-0 Operational Practices in HDR Television. Additionally, the FS-HDR now supports a simultaneous 4K/UltraHD and 2K/HD output mode with independent SDR/HDR controls. Newly integrated BBC Hybrid Log Gamma (HLG) Look Up Tables (LUTs) provide basic, mathematical HDR transforms. Infoframe generation on the HDMI monitor output provides an easy, cost-efficient solution for local monitoring on HDR-capable displays. The release will also integrate new standardized HDR test patterns. Finally, new Tangent Element Kb panel support for remote parameter control enables real-time adjustment control over FS-HDR’s key conversion parameters.

FS-HDR v2.5 feature enhancements include:

• Colorfront Engine support for ITU BT.2408-0 Operational Practices in HDR Television Production

• Simultaneous 4K/UltraHD and 2K/HD/SD dual output mode: In single-channel mode with a 4K/UltraHD input and 4K/UltraHD output, configure the SDI monitor output for SDR/BT.709, PQ/BT.2020, HLG/BT.2020 or Sony S-Log3 S-Gamut3, with these output formats and frame rates independent of the main output:•2K: 2048 x 1080p up to 60p

• HD: 1920 x 1080p up to 60p; 1920 x 1080PsF up to 30p; 1920x1080i 50 and 59.94; 1280x720p up to 60p

• SD: 625i 50; 525i 59.94

• BBC HLG LUTs•Support for HLG HDR dynamic range mapping per ITU BT.2408-0

• SDR, PQ, and Sony S-Log3 to HLG

• HLG to SDR and PQ

• Colorimetry: BT.709 and BT.2020

• HDMI HDR Infoframe generation: Locally monitor HDR content on HDMI 2.0 HDR televisions or monitors. When an output is configured for PQ or HLG, FS-HDR will signal the selected HDR output format to the HDMI display.

• HDR Test Patterns: BT.2111-0 Color Bars and BT.814-3 Pluge

•Support for third party Tangent Element Kb knob-based controller for remote parameter controls

“FS-HDR is an incredibly useful tool for live HDR productions using a variety of sources and delivery formats, and our v2.5 firmware update gives customers even greater flexibility to more easily handle production demands in a single master HDR/SDR environment,” said Nick Rashby, President, AJA Video Systems.


Real-time HDR/WCG Conversion  with Colorfront Engine™ Video Processing

FS-HDR, a 1RU, rack-mount, universal converter/frame synchronizer, is designed specifically to meet the HDR (High Dynamic Range) and WCG (Wide Color Gamut) needs of broadcast, OTT, post and live event AV environments, where real time, low-latency processing and color fidelity is required for 4K/UltraHD and 2K/HD workflows. Developed in partnership with Colorfront, the FS-HDR’s HDR/WCG functionality is powered by Colorfront Engine™ proprietary video processing algorithms. FS-HDR also serves as a full, 1-channel up, down, cross-converter for 4K/UltraHD/2K/HD conversion and frame sync needs and in 4-Channel mode, offers 4 independent channels of 2K/HD conversion.

Real Time HDR Converter

The pursuit of High Dynamic Range (HDR) is the dream of getting closer to the Human Visual System (HVS) in all that we experience as viewers. FS-HDR has been designed to get us all there faster with a low profile, stand alone and real time device uniquely designed to bridge SDR to HDR, HDR to SDR and HDR to HDR,  all in real time.

HDR Conversions:

• HDR to HDR 

• HDR to SDR 

• SDR to HDR

WCG Conversions:

• BT.709 to BT.2020 

• BT.2020 to BT.709

Up and Down Conversions:

• Converting HD SDR BT.709 sources to UHD HDR BT.2020

• Converting UHD HDR BT.2020 sources to HD SDR BT.709

Colorfront Engine™

FS-HDR’s HDR/WCG capabilities leverage video and color space processing algorithms within Colorfront Engine™,  specially-licensed by AJA from Colorfront, and developed by Colorfront’s CTO Bill Feighter and Lead Engineer Tamas Perlaki, both of whom are Academy Award-winners.

Powered by Colorfront Engine, FS-HDR’s extensive HDR and WCG processing support enables real time processing of 4K/UltraHD and 2K/HD, including HDR conversions, and 4K/UltraHD HDR downconversion to HD HDR. FS-HDR also enables the conversion of popular camera formats from multiple vendors into the HDR space, plus conversion to-and-from BT.2020/BT.709 as needed, critical for the widespread acceptance of HDR alongside SDR in broadcast and OTT workflows.

Realtime Camera LOG Conversions

FS-HDR can take incoming imagery from some of the most popular professional cameras in the world today and convert their LOG ouput in realtime to 4K/UltraHD or 2K/HD and output as either HDR or SDR. This greatly simplifies workflows in a mixed camera environment and provides for a unified input workflow to HDR or SDR capable switchers and more.
