A unique identifier assigned to each device within a content protection system.
This identifier is critical in DRM (Digital Rights Management) systems as it helps track devices authorized to access and consume encrypted content.
For instance, a smart TV or a streaming stick like Roku or Amazon Fire TV may have a unique DIS to ensure that only registered devices can access encrypted premium content from streaming services like Disney+ or Amazon Prime.
Is the Device Identifier String (DIS) used to assign a unique identifier to consumer devices for access control in a DRM system?
Yes.
