15:12:51 <narm_gadiraju> ...the intent was to estimate the bandwidth via JavaScript.
15:13:37 <narm_gadiraju> ...they have an API at the top level window object to get the performance information at the HTTP level.
15:13:58 <narm_gadiraju> ...all this can be done via JavaScript

15:14:32 <narm_gadiraju> Duncan: Will this work only through JavaScript and no other method need to be used?
15:15:23 <narm_gadiraju> MarkW:  Yes.  the JavaScript module will directly get the information from HTTP layer.

15:22:55 <narm_gadiraju> Clarke: Reviewing the Usecase: Support Authorized Access to Content 
15:26:20 <narm_gadiraju> Joe:this is high level and requirements of the use case are not discussed
15:26:25 <kaz> s/Usecase/Use case/
15:26:50 <narm_gadiraju> Clarke:this is use case and may need more detail.  Open to changes.
15:27:49 <narm_gadiraju> John:Authorized Access: focus is on Content Protection, but authorized access is a seperate function.  Is there a requirement for supporting authorization itself?
15:28:08 <joesteele> +q
15:28:14 <narm_gadiraju> Clarke: No, a seperate requirement is not captured
15:28:44 <narm_gadiraju> John: We should either separate requirement or expand this.

15:30:36 <kaz> s/seperate/separate/g
15:30:41 <narm_gadiraju> John: In addition Authorization we should look into Device Authentication
15:31:09 <narm_gadiraju> ...this is a requirement for TV devices
15:31:27 <narm_gadiraju> ...should be able to initiate from a web app.
15:32:10 <narm_gadiraju> ...even if Authorization and Authentication are not W3C specs, we should have a way to do it from web app.
15:33:58 <kaz> q?
15:34:01 <kaz> ack joe
15:35:12 <narm_gadiraju> Joe:prefer anonymous for authentication.  Current spec does not cover Authentication.  User Identification is not covered by current spec.  Not sure if appropriate to put in this use case!
15:35:51 <narm_gadiraju> Clarke:Users already have to authenticate.  We need to think if we should formalize this or not ...
15:36:13 <joesteele> -q
15:36:13 <narm_gadiraju> Joe: Upto CDM, not sure if we can standardize
15:36:55 <narm_gadiraju> Aaron:  Authentication may be controversial, because it may make tracking users easier.

15:42:45 <narm_gadiraju> s/these for/these, each for/
15:43:37 <narm_gadiraju> Clarke:container format is to be defined.  
15:47:14 <narm_gadiraju> John:your requirement is written as design guideline and may need rephrasing as a requirement that does not have content protection markup.
