Microsoft & MPEG DASH Licensing  For conformant implementations of the final MPEG DASH specification, Microsoft plans to make its necessary patent claims available under the MPEG patent policy’s royalty -free RAND licensing option.  Any patent licensing commitment to MPEG DASH implementations will not interfere with or change the terms of any other licensing programs. 8-Feb-2011 W3C Web and TV Workshop - Microsoft 4

Digital Rights Management Standards The problem space  Non-interoperable ecosystems  Encoding inefficiencies  DRM-free not an option for high value video  Industry will not settle on a single DRM Solution attributes  Protected adaptive bitrate streaming  DRM interoperability  Common three- (multi-) screen support 2010-04-22 Draft - Microsoft Confidential 8

Why is DRM Standardization so Difficult? Implementations are always proprietary, so how to make interoperable? Ease of Standardisation Difficult Easy Nearly Always present & standardized proprietary. today. Easy. Tied to Tied to compliance rules authentication of of licensing DRM Interoperability is best licensing regime. regime achieved by standardizing the encryption (scrambling) algorithm. 8-Feb-2011 W3C Web and TV Workshop - Microsoft 9

Q1 2011 Final Draft Amendment - ~ July 2011  A standard encryption algorithm is the best way to achieve DRM-interoperability. This leaves the business decision of the DRM technology to use outside the standard.  For broadband television, this standard needs to be compatible with an adaptive streaming standard. 10 8-Feb-2011 W3C Web and TV Workshop - Microsoft
