SilverLight & D.R.M Content

Greetings,

I would like to know if it is possible to play DRM protected content with silverlight.
Could it be possible to develop a silverlight browser application to read some media content and emulate the DRM fonctionnalities of windows media player ?

Thx for your answer.

Re: SilverLight & D.R.M Content

From the FAQ:

Will Silverlight support digital rights management?

For content providers, Silverlight will support digital rights management (DRM) built on the recently announced Microsoft PlayReady content access technology on Windows-based computers and Macintosh computers.

Re: SilverLight & D.R.M Content

DRM will only be supported on Silverlight 1.1. 1.0 is not planned to support it.

Re: SilverLight & D.R.M Content

Yes Play ready will not be Ready until at least 2009

 

That is why Microsoft did a deal with Widevine to provide a Silverlight DRM called Widevine Cypher for Digital Media

http://www.widevine.com/pr/150_silverlight.html

 

I saw it working in the Microsoft booth at NAB #SL5520...also you can see it and a Flash DRM by Widevine in the widevine booth C1251

Re: SilverLight & D.R.M Content

Actually they didn't "do a deal" with Widevine. Widevine has their own encryption technology and they decided to launch this at NAB for Silverlight. Their technology is not, and never will be, compatible with PlayReady. It's an entirely seperate competitive technology.

Re: SilverLight & D.R.M Content

Hello Chris,

 

Actually your are correct and incorrect...WIdevine did not do a deal with "Play Ready" and they are not compatile per se with Play Ready. 

 However Microsoft's "Silverlight" team came to Widevine and requested that Widevine build a DRM for Silverlight.  In exchange for Widevine builing a DRM for Siliverlight Microsoft approved a  press release and gave Widevine space in the Microsoft booth to emo the Widevine DRM protecting Silverlight content.

Microsoft's Silverlight team did this so they would have an alternative to Play Ready especially considering the Play Ready delays.

Re: SilverLight & D.R.M Content

Ross,

HUH? I never said WideVine did a deal with PlayReady. Maybe you are just confused. Thank you for the play by play...alas I already knew all of that but thanks. I was actually there :)  We did a release with Microsoft on the same day on the same subject.

No comment on your last statement.... just cannot speak to that.

 Regards,

 Christopher

Re: SilverLight & D.R.M Content

Oops yes I see I merged your first and last sentence...I thought you were saying that the "Play Reday" group did not do a deal with Widevine.  But you instead were saying that "Microsoft" did not do a deal with Widevine....Did I get that correct?

Re: SilverLight & D.R.M Content

Yes that is what I said. They did a press released with them. There was no "deal" to be done. WideVine has their own technology that works with SilverLight and AFAIK they just did their own implementation and launched the product at NAB. So far not a lot of news there.

Re: SilverLight & D.R.M Content

AFAIK= as far as I know and thank you for making that clear. I had wondered myself how they pulled that off given the lack of SDK on the PlayReady side.  John and his team do a bang up job with that product so it's good to see them getting some "space" as they say :)

we did a similar "deal" but missed the booth space part although we were pretty much just hanging out in their booth anyways kind of with the WideVine team just talking to people and helping guide solutions for the coming year. Good times !

Re: SilverLight & D.R.M Content

Hey Chris,

 I guess the question is why does Silverlight need a DRM...It appears that everyone is deploying Flash without DRM.  I found this to be a useful tool fro recording pretty much everything on Amazon, Fancast, Hulu, etc...

 

Check out this tool and the ideas for watching without advetising is wonderful www.tvadfree.com

Re: SilverLight & D.R.M Content

Hey Ross. Who is Chris? :)  My friends call me Christopher.

The basic need to apply some form of content protection to Internet content is very relevant when you start to look at the paid media arena. Ad-supported content can benefit from DRM tremendously when you are talking about distributed and/or viral business models in P2P and F2F [forward to friend] environments.

 That baing said, the current Ad-supported model for Flash now includes encrypted playlists, an encrypted version of RTMP, SWF hashing and a variety of other mechanisms which will thwart or disrupt or deny products like the one you mention. Of course by not watching the ads or participating in the sponsors' businesses, one is putting a timeline on the media they consume. That's a risk you take I guess :)

 Adobe released a new version of FMRMS today which has greatly expanded their ability to provide paid, ad-supported and enterprise access control for Flash Media. It's safe to expect an expansion of these technologies in the marketplace.

 For Silverlight, DRM affords Windows Media content to become part of more and more PC / Mobile / Lean Back business models. Comes With Music is the first of these models. Device agnostic Zune will be the next wave and I predict an overall surgence of DRM-enabled models where Silverlight is in play.

A good example of a blended Silverlight / DRM business model is in play here: 

 http://shop.abc.net.au/browse/product.asp?productid=954600#PlayerOpen

 ABC is a customer of ours and we think their experience and product is very viable and will kick off a wave of pay-media. It's similar to the product we launched for TV-NZ:

 http://tvnzondemand.co.nz/

This model is a blended ad-supported, pay-media model. Our research shows this to be a strong candidate for the future of how Television specific media is consumed via the Internet.

I hope this information is helpful and I guess we are the lone rangers on this forum... for now :)

Re: SilverLight & D.R.M Content

Hello Christopher,

 

Try out that media catcher on pay content from Amazon....you will see amazing results you get when you do not have DRM!!!

 

 

And Amazon uses RTMPE and swf verfication .... oh but they are still not protecting the content!!!  oh my

Re: SilverLight & D.R.M Content

Which pay-content are you referring to sorry not following you.

 How did you come to the conclusion they are using RTMPe and SWF hashing?  just curious. If that app has cracked RTMPe I would be suprised but not too suprised and definitely not suprised at all when Adobe closes the gap on it.

Soon I am confident Amazon will be using FMRMS.

Re: Re: SilverLight & D.R.M Content

hello

>Soon I am confident Amazon will be using FMRMS.

I am very interested in FMRMS, because recently Flash is getting more and more market share at internet video in JAPAN.

But i am the Microsoft FAN Big Smile ,so i am thinking how to re-get market share by using Microsoft Digital Media Technologies.

5 years ago i developed D.R.M software to protect FlashVideo by using WindowsRMS.

And now PlayReady was releasedWink

Re: SilverLight & D.R.M Content

I will start to evaluate Adobe FMRMS from next Monday.

It was very very expensive Crying

*there is no evaluation version.....

 

As far as i know there are no V.O.D service provider which are using FMRMS.

If anyone know V.O.D serivce using FMRMS , please teach me.

 

And my friend (he is FlashVideo engineer) said that FMRMS is more secure than WindowsMediaDRM/PlayReady.

It is true ? Is there no tool likes FairUse4WM to crack FMRMS ??

 Yeah it's about $35,000 for the FMRMS bits. I would recommend you hold off on doing any evaluations right now and go speak to the FMRMS business lead about the status of the product.

 They will be releasing a product at some point that Providers like BuyDRM can offer a hosted ASP FMRMS solution.

 

As far as i know there are no V.O.D service provider which are using FMRMS.

If anyone know V.O.D serivce using FMRMS , please teach me.

There are not as of yet because Adobe has not released the product to their service provider partners as of yet.

 

And my friend (he is FlashVideo engineer) said that FMRMS is more secure than WindowsMediaDRM/PlayReady.

It is true ? Is there no tool likes FairUse4WM to crack FMRMS ??

Yes and if a fish dies in the middle of the ocean does anyone really know? FMRMS has not been released yet so sure there are no tools to crack it as of yet because it's not a technology in play. Once it is in the public domain and well deployed and in play I imagine there will be attacks and I imagine that Adobe will respond in kind.
