D‑Cine Player · 4.2.32 release
DDL - D-Cine Display Lock
Bind protected playback to one or more qualified display chains without forcing a post-production player to remain in one room.
Enroll several displays
Approve grading monitors, client projectors, screening rooms and controlled service replacements for one player.
Content-selected assurance
One player certificate supports DDL1, DDL2 or DDL3 targeting through the KDM’s signed AnnotationText—compatible with familiar KDM creation workflows.
Qualified control
Authority-managed user permission controls enrollment and removal, with a reviewable record of successful and denied requests.
Recognisable display inventory
Pair the authoritative EDID fingerprint with available manufacturer, model, serial, manufacture date and physical-size details.
Layered identity
Use authenticated HDCP for DDL1, enrolled EDID fingerprints for DDL2, and authenticated receiver identity/topology for hardware-qualified DDL3.
Two-year activity history
Signed-in Authority users can review authorization, enrollment and removal history—including player serial, requested/achieved level and display identity—for 730 days.
SDI DCP playback uses a separate DDL1 policy and refuses DDL2/DDL3 requests. SDI does not implement HDCP on the wire; EAR’s default authenticated-HDCP requirement remains in force. Qualify the permitted media/output combination with the content owner.
