+ hdr10 metadata of video contents.

+ Warning! The protocol described in this file is experimental and backward

+ incompatible changes are done by bumping the version number in the protocol

+ is to be declared stable, the 'z' prefix and the version number in the
+ protocol and interface names are removed and the interface version number is
+ reset.
