Colleagues,

An important topic at this year's W3C Technical Plenary meeting was the 
elevation of video and audio objects as first-class objects in an HTML 
presentation.

In the current HTML-5 specification, a new set of elements and 
attributes are proposed to facilitate this promotion.
Since the W3C's Synchronized Multimedia working group (SYMM WG) has been 
looking into related issues for the past 11 years in several editions of 
the SMIL language, we felt that it might be useful to summarize SMIL 
timing and media control concepts already in place, so that maximum 
re-use of existing Web technology can be facilitated.


"An Overview of SMIL Timing and Media Attributes for Audio and Video 
Objects" [1], is a document targeted to become a W3C Working Group Note, 
provides an overview of the basic timing, media control and temporal 
linking concepts that are used within a SMIL presentation. It should 
enable maximum re-use of existing Web technology in other XML languages.

Regards,


Thierry Michel, SYMM WG staff contact
On behalf on the SYMM WG co Chairs.
