Let’s get technical
DRMtoday for Widevine CAS workflow
- At the headend, a scrambler encrypts the source video with often changing scrambling keys (control words). This is usually performed by a headend multiplexer.
- 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).
- The ECMG talks to our DRMtoday license server over HTTPS to ingest and pull entitlement keys.
- The ECMG embeds the entitlement keys together with additional metadata into an Entitlement Control Message (ECM) and sends this back to the SCS.
- The headend sends the ECM to the Android TV device with the encrypted broadcast video.
- On the STB, our Widevine CAS enabled PRESTOplay player software asks DRMtoday for the entitlement key via HTTPS.
- 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.

Group licensing
Combine multiple individual channels within a group license. A single group license can then be delivered which is valid for any channel within the group. This is useful to simplify delivery loads and improve channel change latency.
|
|
|
License pre-fetching
When a license expires a new license can be automatically available ahead of time to use. This helps to avoid playback delays and mitigates against latency when changing channels.
|
|
|
License renewals
This is useful for subscription management. For example: An issued license may have a preset time limit. When it expires a STB can automatically try to renew the license. If the user still has a valid subscription then the license is renewed, and if not the request is denied.
