Hi all,

This is a quick update of some recent activity and upcoming
calls/meetings - next week in particular is looking busy!

Current work on some key specs that are important for TV/broadcast were
highlighted in a recent Mozilla Hacks blog post - "How TV Functionality
Leverages Web Technology":
https://hacks.mozilla.org/2015/05/how-tv-functionality-leverages-web-technology/
I recommend this as a good overview with some helpful snippets of code.

== Second Screen Working Group ==
The group is holding a face-to-face meeting in Berlin next week -
19th-20th May:
https://www.w3.org/wiki/Second_Screen/Meetings/May_2015_F2F
The agenda on the above page gives a good overview of the priority
issues that will be discussed. You can also get a grasp of recent
changes by looking through the spec changelog on GitHub:
https://github.com/w3c/presentation-api/commits/

== Device Timing Community Group ==
Ingar and Njål from the group have published a paper "highlighting the
importance of precise timing for Web-based media, both in single-device
and multi-device scenarios". This addresses the need for fine precision
for HTML media elements that use a timing mechanism and introduces the
Multi-device Timing Community Group's work. They'll also be representing
this Community Group at WWW2015 in Florence, Italy next week. See
Ingar's mail for more details and links:

== TV Control API ==
There's a monthly conference call today (12th May) at 9:00am EST (see
http://timeanddate.com/s/2txa ). New participants are very welcome to
join in, in which case reading the Mozilla blog post above is recommended.

Bin Hu has posted links to today's agenda which also gives a good
overview of what the current focus points are:

== HTML Media Task Force ==
Two interesting issues that came up at the recent face-to-face meeting are:
* Alternate content insertion
  This proposal was originally intended for MSE but has a potentially
wider impact. Please see my earlier mail to provide comments and feedback:
  https://lists.w3.org/Archives/Public/public-web-and-tv/2015May/0001.html

* Associating video and audio transcripts
  There is renewed interest in being able to semantically bind video or
audio content with a transcript, either on the page or in a separate
document. After various discussions a solid proposal is taking shape and
looking for feedback. More details in this mail:
  https://lists.w3.org/Archives/Public/public-html-media/2015May/0027.html

== GGIE (Glass-to-Glass Internet Ecosystem) ==
Recently there have been camera use cases added for capturing digital video:
https://www.w3.org/2011/webtv/wiki/GGIE_TF/UseCases/Content_Capture

These and other use case issues and suggestions may be discussed on the
next call next Wednesday (20th May) at 11:00am EST (see
http://timeanddate.com/s/2txb ).

== 3D Web ==
Amit from tvereo.com has been looking into 3D web content following the
(now closed) Task Force's work:
https://www.w3.org/2011/webtv/wiki/3dweb
He's looking for feedback on a proposal for how 3D elements could be
incorporated in a 2D page on a device that supports 3D, such as smart TVs:
https://lists.w3.org/Archives/Public/public-web-and-tv/2015Apr/0010.html

Phew! Busy times. Feel free to reply or start your own thread with any
other noteworthy news or questions.

With regards,
Daniel Davis
W3C
