Session control with SSM
Overview
OpenTV Video Platform uses the Secure Session Management (SSM) service, part of NAGRAVISION's Security Services Platform (SSP), to limit the number of concurrent streams consumed by client apps.
You can define two kinds of session limit (in OpCon):
An account-level session limit is defined in an account profile an applies to all the accounts that have the account profile assigned to them.
A device group session limit applies a session limit to groups of devices (for example, only to mobile devices) for all accounts.
Optionally, you can also define groups of channels and define a session limit for each channel group.
A client app attempts to set up a session for each new playback session, and SSM enforces this limit. While playing content, the app must send keep-alive requests at regular intervals. If it fails to do so, SSM will end the session and playback will stop.
After playback, the app must tear down the session. This allows SSM to decrement the session count.
The following client use cases are supported:
To integrate against SSM, you will need to refer to the SSM API documentation. This is part of the SSP portal – to get access, please contact your NAGRAVISION representative.
