Let’s get technical

DRMtoday for Widevine CAS workflow

DRMtoday for Widevine CAS architecture
  1. At the headend, a scrambler encrypts the source video with often changing scrambling keys (control words). This is usually performed by a headend multiplexer.
  2. The Simulcrypt Synchronizer (SCS) sends these control words to the Entitlement Control Message Generator (ECMG) which wraps them with another, seldom changing service key (entitlement key).
  3. The ECMG talks to our DRMtoday license server over HTTPS to ingest and pull entitlement keys.
  4. The ECMG embeds the entitlement keys together with additional metadata into an Entitlement Control Message (ECM) and sends this back to the SCS.
  5. The headend sends the ECM to the Android TV device with the encrypted broadcast video.
  6. On the STB, our Widevine CAS enabled PRESTOplay player software asks DRMtoday for the entitlement key via HTTPS.
  7. If the customer is authorized, DRMtoday delivers Entitlement Management Messages (EMMs) which are special Widevine licenses containing the entitlement keys needed to unwrap control words. The broadcast stream can now be safely decrypted and played.
