. HDMI 1.4:
"Roland Vlaicu, Dolby VP:
We had anticipated the challenge of getting high dynamic range (HDR) and HDR metadata over HDMI interfaces. So what we did was develop our own technology that tunnels all the way through HDMI interfaces back to version 1.4, including the signaling and the metadata. So for televisions that have HDMI inputs and present Dolby Vision signals, as a requirement from us, the HDMI inputs have to support Dolby Vision in addition to the on-board OTT apps that support Dolby Vision and in order to make that work we developed in-band signaling as well as the ability to send 12-bit video over what is effectively an 8-bit interface. All this is implemented in televisions and storage devices that support Dolby Vision.”

Dolby Vision receiver pass-through compatibility: pass-through Dolby Vision video signal with embedded Dolby Vision metadata
"Dolby Vision can technically be routed through any equipment starting at v1.4.b and above, however, the device needs to be aware of the kind of signal properties that differentiate Dolby Vision from a standard SDR signal. To this effect, we have issued a compatibility SDK that several manufacturers have already used to obtain pass-through compatibility on upcoming products. Compatibility on existing products is something that could possibly achieved as well, but is of course at the discretion of each manufacturer/OEM."

HDR10 Media Profile:
"A TV, monitor or projector may be referred to as a HDR Compatible Display if it meets the following minimum attributes:
. Includes at least one interface that supports HDR signaling as defined in CEA-861-F, as extended by CEA-861.3.
. Receives and processes static HDR metadata compliant with CEA-861.3 for uncompressed video."

HDMI:
"We support HDR static metadata that is referenced in CTA 861.3. As the industry and features/formats develop, we will certainly evaluate supporting additional formats.
There is additional metadata is that required to deliver the enhancements offered by HDR. HDMI 2.0a adds the ability for devices to be able to transmit/receive this metadata."

"The HDMI Forum has confirmed that the extension of the static metadata signaling to include HLG can be utilized under the existing HDMI 2.0b Specification."

Probable future ST 2094-10 compliant ATSC 3.0:
"This document describes technology documented in ST 2094-10 “Dynamic Metadata for Color Volume Transform — Application
#1” which is a technology for the use of dynamic metadata for HDR content. If approved by the ATSC, A/341-Video-HECV (date of current public version) (“A/341”) would be amended according to the edits described herein.
The HEVC video bitstream may contain the 2094-10 metadata message in order to provide dynamic information about the video signal. When a 2094-10 metadata message is present, this information can be employed by the display to adapt the delivered HDR imagery to the capability of the display device. Furthermore, this metadata can be used to derive an SDR (ITUR BT.709 [ref]) picture by receiving devices such as an ATSC 3.0 receiver/converter."
