TTML Profile Registry (aka Codecs Registry)

Colleagues-

 

Per an action item from this week's meeting, this is a status of the
registry, a next step and a proposed process to publication.

 

The registry has been somewhat misnamed "Codecs Registry" and should be more
properly, "Profile Registry".  ("Codecs" came from the primary use in the
DASH @codecs.)

 

The table values were recently updated to reflect: 1) input from EBU and 2)
a decision to identify versions in the codes.

 

We also recently agreed that codes should be limited to 4 characters to
facilitate future consideration in the MP4RA registry (and thus needs a
sentence or two in the body of the registry page that they are so
constrained).

 

If everyone is satisfied with the above, then the registry is needed by the
industry ASAP.  Although the registry and its codes are cited in TTML2 (but
not TTML1), it is needed externally today for TTML1 (e.g. DASH).  Therefore
this needs to be put on a path to publication ASAP.

 

The registry is an administrative tool with published rules for maintenance.
As such, I believe this should published as a WG Report, and thus only needs
TTWG consensus to publish and revise.

 

Regards,

 

                Mike
