Figure 9. HDR Playback Screen Tab
The HDR screen provides a sub tab setup for HDR playback simultaneously via
both SDI and HDMI.
For SDI destinations, the HDR data is delivered in-band using VPID signaling for
SDR/HDR Transfer Characteristics, Colorimetry and Luminance.
For HDMI destinations, side-band information is used to inform an HDMI sink
device (such as a TV or monitor) that the video content is HDR. This includes
generation of the Dynamic Range and Mastering Infoframe and the static
metadata descriptors as defined in CTA-861.3 and HDMI v2.0a.
Included are preset primaries values for BT.2020 and DCI P3 color gamuts.
Two tabbed screens are available, for Capture and Playback. The HDR Capture tab
settings affect the HDR metadata saved with your captured video, and the Io X3's
HDMI and SDI outputs while in Capture mode. The HDR Playback tab settings
affect what HDR metatdata is included on the Io X3's HDMI and SDI outputs while
in Playback mode.
