Interface VideoColorInfo

The dynamic range of the video representation.

Describes the encoded signal, not the image the display produces, which can be a tone-mapped SDR rendering of HDR content.

Derived from manifest information in this order:

1. An explicit dynamic range signal:
   • HLS: the VIDEO-RANGE attribute of the EXT-X-STREAM-INF tag describing the variant
   • DASH: the CICP transfer characteristics of an EssentialProperty or SupplementalProperty descriptor of the Representation, or of its AdaptationSet
2. What the codec string implies, stated by CODECS in HLS and codecs in DASH:
   • a Dolby Vision codec string states HDR, as Dolby Vision content carries an HDR presentation
   • a fully specified VP9 or AV1 codec string states CICP color information
   • 8 bit rules out HDR, stated as a bit depth by VP9/AV1 and implied by the profile for AVC/HEVC

Unknown is reported when neither identifies one. It is distinct from a confirmed SDR.
