            Bug ID: 28483
           Summary: Improvements to MPEG-DASH and MPEG-TS sourcing
           Product: HTML WG
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Sourcing In-band Media Resource Tracks

In the table of contents, "MPEG DASH" should be "MPEG-DASH".

It wasn't immediately clear to me that we created a track for each
ContentComponent or AdaptationSet, so I think that should be more specific.

In DASH, higher-level attributes contain default values for lower level
attributes. The spec should make it clear that you should try to source values
from the ContentComponent, and then use values from the AdaptationSet if you
don't find them.

I have a feeling that service_number is going to be extremely collision-prone
as an "id", so I suggest prefixing it with "sn-".

MPEG-TS table_id is almost never unique, so it makes a poor cue "id". Also, the
spec currently discards section_syntax_indicator and private_indicator. It
seems simpler to just throw the entire table in there and let people do what
they want with it (since this is metadata that the UA explicitly doesn't
understand).
