答复: Encrypted Media Extension bugs for discussion during 2012-06-12 teleconference

Hi David and all

Can anyone give me an introduction/background material (email, txt, word or ppt) about this encrypted media extension?
I plan to attend today’s conference call, and I am reading the bugs listed below.
Thanks a lot if any.

I changed the table to plain text below so it is hopefully more readable in the archives.

In the first HTML WG media teleconference, we will discuss as many of the following Encrypted Media Extension bugs as we can get through. (See http://tinyurl.com/7tfambo for a full list.) I've provided some brief notes for each bug below the list. I'll also start threads for some of them.

ID          Sev Pri  OS  Assignee                           Status    Resolution    Summary
16612^  nor  P1   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Consider wrapping all encrypted media methods inside a new interface
16613    nor  P1   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Consider a more object-oriented design in which sessions are represented as objects
16548    nor  P2   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Require generateKeyRequest() in all cases for all Key Systems
16549^  nor  P2   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Remove initData parameter from addKey()
16552    nor  P2   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Consider making needkey a simple event
16738    nor  P2   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Provide more guidance on heartbeat implementation
17199    nor  P2   All  adrianba@microsoft.com<mailto:adrianba@microsoft.com> NEW     ---    Provide examples for and get feedback on Key Release

^ We will defer discussion of these since they depend on other bugs in this list.


* 16612: Read for background, but we will defer discussion until we decide on 16613.
* 16613: This is the most important since so many other bugs depend on or are affected by it. I've added some pros and cons as well as references to many other bugs that may be at least partially addressed by objects. There is a link to a formatted version of the bug in Comment 3<https://www.w3.org/Bugs/Public/show_bug.cgi?id=16613#c3>.
* 16548: Summary: Making the uncommon simplest case slightly more complex simplifies implementation and increases consistency.
* 16549: Read for background, but we will defer discussion until we decide on 16613 and 16548.
* 16552: Are there strong preferences for simple vs. complex events? Note that we could consider making all events simple if we address 16613.
* 16738: How should heartbeats be implemented? keymessage followed by a reply using addKey() or as separate key requests/sessions?
* 17199: It would be good to get more feedback in the area of key release, especially regarding whether KeyReleaseManager should be a singleton and/or a member of window.
