Protected Content in Browsers
Protected
Content in
Browsers
Position Paper
Background
› Current Service Provider strategy to deliver protected
content
– Use multimedia framwork that has support for DRM e.g. Silverlight,
Flash
– Browser plugin that handles both DRM and media playback
– Native Client
› Legacy plugin architectures have poor security and stability
– Major browser vendors are dropping plugin support
– New plugin architectures exist, but are not broadly supported
› Encrypted Media Extensions (EME) provide APIs to control
playback of protected content
– DRM system support is up to browser vendor

Options
› Deploy multi-vendor DRM support and adopt to DRM

› Support only one or a few browsers

Statements
› In mid-2014, the blocking UI will become more difficult to
navigate, as a means of discouraging NPAPI use by
developers. With the harsher blocking UI, users will see a
puzzle piece in place of the plug-in and a "Blocked plugin“…

Conclusion
› User experience will suffer because of non-preferred
browser or native application
› Anti-competitive situation because of the nature of DRM
support in different browsers.
› Discussion is invited
