4K Closed Caption Support

AJA Control Room software now supports ingest and playback of 4K content that carries Closed Captions when using a KONA 5, KONA 4, Io 4K Plus or T-TAP Pro.


HDR or High Dynamic Range,  provides the ability to display a wider and richer range of colors, much brighter whites, and much deeper, darker blacks than standard signals allow. This gives your imagery a more ‘dynamic’ look and allows for natural true to life colors to be communicated to your audience.

HDR workflows can also benefit from AJA's Control Room application and it's  companion, AJA Control Panel, which comes complete with built-in HDR test patterns.

AJA Control Room also provides VPID signaling for SDR/HDR Transfer Characteristics, Colorimetry and Luminance transfer characteristics over SDI, bringing flexible output options to your AJA device. 

AJA Control Room can also feed HDMI HDR displays, offering HLG and HDR10 support with HDR Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.G, for compatible KONA, Io and T-TAP products. HDMI ports that were already HDR compatible will work simultaneously, for HDR output via both SDI and HDMI.

AJA Control Room software further offers HDR Auto Playback Detection. Embedded HDR metadata in a recorded .mov file, is read and used to automatically set the HDR format on the monitor(s) connected to the AJA HDMI and/or SDI outputs.

Support for file-based .mov HDR outputs with metadata from Adobe Premiere Pro/Adobe Media Encoder HDR files is also available. Screening those rendered outputs is a simple and hi-quality experience with AJA Control Room. Every frame is presented in its full-quality, at the timing intended, and with the proper HDR format set correctly and automatically.
