Widevinecdm Chrome (2026)

For L1 devices, Widevine CDM enforces HDCP (High-bandwidth Digital Content Protection). If a monitor does not support HDCP 2.2+, the CDM may restrict output to 720p or refuse playback for 4K content.

| Level | Description | Chrome Implementation | |-------|-------------|------------------------| | L1 | All content processing and cryptography within a Trusted Execution Environment (TEE). | Achievable on Chromebooks and systems with Hardware Security Module (HSM) support (e.g., Intel SGX, ARM TrustZone). | | L2 | Cryptography in TEE, but decrypted content may leave TEE for video processing. | Rare in modern Chrome; fallback when L1 unavailable but secure key storage exists. | | L3 | Both cryptography and content processing in software (CDM runs in user space). | Default on most desktop Windows, macOS, and Linux systems without Widevine-certified hardware. | widevinecdm chrome
