Hi Mark How is the CDM provisioned in the first place? Or is that our of scope for EME? I assumed that the CDM would get this information (e.g. server certificate) during the initial provisioning. Thanks, Petr From: Mark Watson [mailto:watsonm@netflix.com] Sent: Monday, February 03, 2014 9:32 PM To: Paul Cotton Cc: public-html-media@w3.org Subject: Re: {agenda} HTML WG media telecon 2014-02-04 - EME bug discussion All, Regarding bug 24025 (Add optional configuration parameter to MediaKeys constructor) there is a request for use-cases (actually on 24082). It seems something which might be quite common is the need for the CDM to be provided with a server certificate which would allow the CDM to encrypt its messages to a specific server. Amongst other things this has user privacy advantages. I think this provides motivation for the proposal in 24025 and we might even want to consider whether the server certificate use-case should be explicitly supported in the specification. ...Mark On Mon, Feb 3, 2014 at 7:35 PM, Paul Cotton <Paul.Cotton@microsoft.com<mailto:Paul.Cotton@microsoft.com>> wrote: The HTML WG media teleconference meeting will occur on 2014-02-04 for up to 60 minutes from 15:00Z to 16:00Z. http://timeanddate.com/s/2j4x Tokyo midnight, Amsterdam/Oslo 17:00, London/Dublin 16:00, New Jersey/York 11:00, Kansas City 10:00, Seattle/San Francisco 08:00.
