Every OTT platform claims DRM support. That claim means almost nothing to a studio licensing team.

When a major studio hands you a content-protection schedule, it doesn't ask whether DRM is present. It asks which DRM systems are supported, at what security levels, on which device families. It asks whether HDCP output protection is enforced. It asks how your platform handles a device that reports the wrong security level mid-stream. And for anything in an early release window, it asks how a leak gets traced back to the session it came from.

These aren't philosophical questions. They're contractual requirements with audits behind them.

The Motion Picture Association and the Trusted Partner Network exist precisely to verify this stack before a single frame of premium content ships. Fail that assessment and the licensing conversation ends before it starts.

Three things catch operators off guard every time. First, Widevine has security levels — L1 is hardware-backed, L3 is software — and studios require L1 for HD and UHD, not just "Widevine enabled." Second, FairPlay certificates run on their own renewal cycle, entirely separate from everything else. Let one lapse and Apple playback stops dead while every other platform keeps working fine. Third, for early-window content, forensic session-based watermarking isn't optional — it's how studios make leaks traceable and therefore deterrable.

If you're building toward a studio licensing deal and want to understand exactly what the protection stack needs to look like tier by tier, this guide on DRM compliance for studios covers the full MPA and TPN framework, the four protection tiers from catalog SD to 4K early-window, and how to choose a platform that passes a security review the first time.
