Cloud Video Platform: Content rights guide

Content rights management is how a streaming service enforces the rules attached to each title: who can watch it, where they can watch it, and when. The entitlements system sets those rules, and DRM provides the technical mechanism that enforces them on each device.

The guide explains the Content Rights services within the Cloud Video Platform Rules services, the business cost of piracy, managed multi-DRM, hosted Widevine licensing, the CVP Key Management Service, and how CMAF supports protected streaming. It is written for content providers, telecommunications companies, and pay-TV operators.

The Cloud Video Platform from Comcast Technology Solutions supports Apple FairPlay Streaming, Microsoft PlayReady and Google Widevine through a managed multi-DRM service.

Different devices support different DRM systems. A multi-DRM setup lets one service reach a larger audience on a wider range of devices while meeting the security requirements of content owners, studios, and broadcasters.

CPIX, the Content Protection Information Exchange Format, is a DASH-IF specification for securely exchanging content keys and DRM information between systems such as packagers and key management services. The CVP Key Management Service supports CPIX version 2.3.

CMAF lets a single set of encrypted media files work across multiple DRM systems and both DASH and HLS, instead of storing separate copies for each. That can lower live latency and reduce encoding, packaging, storage and CDN costs.
