14.3Summary of discussions

M18675 No comment. Pending issue: bit ordering in the ‘colr’ extension for the full_range flag is different from JPEG XR (where we got the field from) and no-one knows why. Note needed? No action at this time.
M18711 US made comment. Successfully resolved.

m18754 Thank you, see the disposition of comments report.

m18938 Thank you, we believe we have handled the issues in the revised text.

m19307 On data references, we will make clear that in the case that a self-contained file is segmented for delivery, the data references nonetheless are same-file references. On the edit list box, we will add a note that an edit list in the movie may, in the case that movie fragments follow, involve the media inserted in those movie fragments (media which is invisible to a non-fragment-aware reader).

m19338 Thank you, see the disposition of comments report.

m19308 Thank you, accepted into the amendment (which needs the section number references fixed).

M19132 Thank you for the revised open-GOP signaling; we will use it in the PDAM3 DoCR.

M19133 Thank you for the proposed corrections. We will issue a WD of COR here, to allow careful study before issuing a DCOR in the next meeting.

M19309 This is a fascinating and powerful idea – perhaps too powerful? However, the edits to part 12 are quite small. We’d need a new handler type, a codec type for ISO BMFF files, and their sample entry defined, and some small text on what chunk offsets mean in level 1 contained files. To a [wd of amd][new amendment]…

M19394 Accepted in principle, contributors and editor to work on the precise text.

M19471 Accepted to merge the two ideas into a single box, into the amendment, with care about the terminology. Segments with this box and these characteristics should have a distinct brand, or maybe two (single-track, and multi-track cases). These brands go into the DASH spec.
