Licence log

    • The check above is live. On a device without hardware-backed decode it refuses to play, as a real exam deployment would.
    • There is an override button so you can see the player regardless. A real deployment would not have one.
    • Playback uses Google's public Shaka test video and an unauthenticated test licence server. No real exam content is involved.

    The problem

    Exam video is the hardest case in corporate media. The content is worthless once it leaks, and the people watching it have a reason to copy it. A question bank that reaches a forum invalidates the sitting, and sometimes the accreditation behind it. Here the strict settings are proportionate: hardware-backed decode, output protection, one device, a licence that lasts minutes, and a watermark that identifies the candidate in any recording that gets out.

    What this demo shows

    • A policy check that refuses playback, and says why, if your device cannot do hardware-backed decode
    • An HDCP 2.2 check against your current display and cable
    • A visible watermark that moves around the frame, so it cannot be cropped out without losing the picture
    • Why one device and a short licence matter most for this use case
    • The record of licence decisions an awarding body will ask to see

    The policy, and why it is set this way

    Each setting trades protection against convenience. The settings that suit exam video would make compliance training unwatchable for many of the staff who need it.

    EntitlementBooked sitting, identity verified
    The licence is tied to a specific exam booking. Outside the booked window there is no key to issue.
    Licence duration90 minutes, single use
    The licence ends with the sitting, so one captured in transit is useless an hour later.
    Concurrent devices1
    A second device during an exam is either a second person or a recording rig. Either way, it should be refused.
    OfflineRefused
    A persistent licence would leave the content on a candidate's disk with a key next to it. That is never acceptable for question material.
    RobustnessHW_SECURE_DECODE
    With software decode, decrypted frames end up somewhere a determined candidate can reach. Hardware-backed decode keeps them in the protected path.
    Output protectionHDCP 2.2 required
    HDCP stops a cheap HDMI capture card and casual screen mirroring. It will also refuse a candidate with an old monitor, and you accept that support cost on purpose.
