AJA FS-HDR Specifications

FS-HDR

FS-HDR, a 1RU, rackmount, universal converter/frame synchronizer, is designed specifically to meet
the High Dynamic Range (HDR) and Wide Color Gamut (WCG) needs of broadcast, OTT, production,
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 FS­HDR’s HDR/WCG functionality is powered by Colorfront Engine™ proprietary video processing
algorithms.

In Single Channel mode, FS-HDR also serves as a full, 1-Channel up, down, cross-converter for
4K/UltraHD/2K/HD HDR transformation. In 4-Channel mode, FS-HDR offers 4 independent channels
of 2K/HD HDR/WCG transformations as well as up, down, and cross conversions.
