Re: Welcome to the DAP WG

Frederick, all,

Thank you - it is good to be here.

As some of you will be aware, Netflix is a large provider of streamed video content over the Internet, currently operating in the US and Canada. We recently joined W3C as we are interested in ensuring that web technologies, as they evolve, can support services such as ours. We have a great deal of experience delivering adaptive video streaming over HTTP on the Internet and using HTML/CSS/JS technologies for our User Interfaces.

Personally, I have recently been very involved in the MPEG activities to define a standard for adaptive streaming over HTTP (DASH).

My interest in the DAP WG is based on the discussions at the recent W3C Web & TV workshop [1].

There are some APIs (some of which were discussed at the workshop) which we believe would be required to deliver commercial video streaming services using web technologies and which might be appropriate for the DAP working group:
- An API for secure device authentication
- A secure version of web storage
- Some additional system information related to video capabilities (could be added to the System Information API).

Also there are some other interesting features, such as collection of adaptive streaming metrics and selection and configuration of adaptive streaming algorithms where I am not sure about their correct home in W3C.

I expect requirements for these to be discussed in the new Web and TV Interest Group [2] and then raised in the context of the DAP WG recharter (though I am not that familiar with W3C process yet).

Regards,

Mark Watson

Welcome to you and Netflix to  the Device APIs Working Group!

If you have not already done so, please review the group charter  [1],   the public working group page and its roadmap [2], and the  approved and draft meeting  minutes [3]. The working group page has information on our meetings  [4], including our weekly teleconferences. You will want to use IRC at meetings [5] and if  a dedicated IRC client does not work you can use the web client [6].

All of our technical work is to be done on our public  mailing list ( public-device-apis@w3.org<mailto:public-device-apis@w3.org> ) [7].

Our next face-face meeting is scheduled for March 15-18 2011 in Seoul, South Korea (including an optional public workshop day on March 17). We have a registration page [8] and logistics information available [9]. Draft information on the workshop is also available [10]. Please complete the registration page regarding your plans to attend the F2F meeting.

Please introduce yourself on this mailing list, indicating who you  are, why you are interested in participating in the Device APIs  WG,  which parts of the charter are of particular interest, your expectations, and where you might be able to contribute.

Thank you, and welcome to the working group.

regards, Frederick
