OG-Hi5-4K-Plus 3G-SDI to HDMI 2.0 Converter v1.0 24 www.aja.com
The HDR tab provides a mechanism to inform an HDMI sink device (such as a TV
or monitor) that the video content is HDR encoded. 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. This tab includes pre-canned primaries
values for BT.2020 and DCI P3 color gamuts.
NOTE: The OG-Hi5-4K-Plus HDR function does not modify the video data.
