Use Case 3: Querying device capability

Owners and Supporters

• Fraunhofer Fokus

Use Case Description

• As a content provider, I would like to query whether I can play back my UHD with high DRM security level and certain codecs on a certain device.
• canPlayType() [2] has been mentioned in this TF already and is not useful in most cases, since it returns “probably”, “maybe” or “”
• For certain device types (e.g. mobile) I might even want want to know whether playback of a codec is hw-accelerated or not.
• EME robustness [3] property to query CDM security level is another example, which does not return useful values across browsers and DRMs today.
