Summary: Proposes a new element for metadata track, equivalent of adaptation set.
Resolution: a simpler solution seems to be either
-
Expand the definition of dependencyId to be association when the representation is a metadata track.
-
Introduce a new attribute: associationId.
It seems (2) is preferable to (1). We need to investigate other possibilities. We will make the decision next meeting.
m32291 Metadata Representation Carrying Green Information Signalling for DASH
Summary: FF will support green metadata track including two codec types. Proposes to create green metadata adaptation sets for each of these codecs. The metadata needs to be linked to video presentation. It is proposed to use dependencyID to link the representation across the corresponding adaptation sets.
Resolution: The only additional signaling is needed in DASH is linking the green information and the corresponding representations. We will address this need with quality metadata tracks.
