AJA FS-HDR Real-time HDR/WCG Converter

About: AJA FS-HDR Real-time HDR/WCG Converter

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 HDR transformation, conversion and frame sync needs and in 4-Channel mode, offers 4 independent channels of 2K/HD conversion including HDR transformations.

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 and BT.2020 

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™ Maintaining Perceptual Integrity

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 a single channel of 4K/UltraHD/2K/HD including down-conversion to HD HDR  or up to four channels of 2K/HD simultaneously.  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 output 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. Additionally, FS-HDR provides the ability to convert to Sony S-Gamut/S-Log3 on output from any of these sources for workflows requiring this Log feed to compatible switchers and more.
