Multikey DRM
Multi-key DRM strengthens content protection by assigning separate encryption keys to different tracks—for example, isolating HD video from shared audio and SD streams. That isolation improves security and unlocks higher-resolution playback on capable devices, but it comes with trade-offs: legacy and low-powered clients often cannot handle multi-key licenses or signaling, so operators are forced into parallel packaging or reduced quality for those audiences. This talk explores the pros, cons, and practical limits of multi-key DRM in production VOD pipelines, then shows how a hybrid multi-key approach works around them—emitting both single-key and multi-key manifests from one package, reusing identical media segments, and varying only DRM signaling so every device gets the right protection without duplicate encryption.
