Re: Minutes from MEIG meeting 5 November 2024

Dear Chris and all.

Thanks again for inviting to this meeting!

To reiterate some key points from my side.
- I regard "timing model for the Web" as a topic of general interest for
the Web community at large. Though the activity level in the CG group has
been low, timing is a recurring theme across many groups and application
domains. The meeting disussion also included additional examples of related
discussions and/or intitiatives in other groups.
- I regard the "MEIG" as the IG where this topic most naturally belongs.
- I'm ok with closing the CG group, but I'm of course hopeful that some of
the key ideas can live on with the IG.

Some takeaways from the CG work
- Timing is the most imporant part. The timing object is a suggestion for a
minimal, common representation of logical/virtual timeline playback
(support for acceleration can be dropped), to be used for coordination
across components and frameworks within a Web page, or across Web-pages
hosted by different devices.
- Opening up for distributed sync of timing objects is a key purpose of the
timing object, but there is no suggestion for a particular protocol or
approach for this. This is intentially left open, so that organisations and
developers can explore different options. Agreement on a common timing
object would still remains highly valuable, as it provides separation
between application code and the particular approach to distributed sync.
- For maximized utiltity, we recommend that time representation is not
bundled with other concepts, e.g. session management.
- Syncing media elements precisely in reference to a logical clock is a
hugely important case, and the current complexity of doing this is seen as
a showstopper for a wide variation of applications, both in the
entertainment/media domain, and in other industries (e.g. playback of IoT
sensor data visualizations along with captured video).

Things to do from here
- A testing suite for the "syncability" of media elements would be useful,
as suggested by Louay. I've attached two technical reports which Njål and I
made back in 2014/15.

Best regards,

Ingar Arntzen
