Reference Service: Device-Binding Entitlement
The SEES reference server shows you how to enable the device-binding entitlement service using ExpressPlay.
The device-bound entitlement service can also be time-bound or provide rental duration.
To bootstrap the device_id information, playback a dummy M3U8 content. You can then embed a cookie in the ExpressPlay token, generate an SPC (which contains the device_id ), and send a getToken to the ExpressPlay Server.
The sequence starts by playing a dummy M3U8. A cookie is sent to the SEES server to get the ExpressPlay token URL. After receiving the cookie-bound ExpressPlay token URL, the next step is to generate the SPC and send it to the ExpressPlay Server. The ExpressPlay server extracts the device_id from SPC, the cookie from the ExpressPlay token URL, and puts the cookie and device_id in the transaction log.
The client makes a real license request to SEES sending the same cookie. SEES employs the cookie to retrieve the device_id from the ExpressPlay server.
SEES requests an ExpressPlay token that is device-bound as well as time-bound and returns that token to the client.
The client makes the license request with the ExpressPlay token.
The ExpressPlay server compares the device_id in the SPC with the device_id in the ExpressPlay token. The ExpressPlay server only issues a license if the two device_id values match.
