Managing playback sessions

Overview

OpenTV Platform uses the Secure Session Management (SSM) service, part of NAGRA'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. You can do this:

• In OpCon – see Session Group Management. Once you have defined a group, you need to add each channel to it – see the Session Group field in Manage channel playback variants.

• At ingest:

  • File-based ingest – see the sessionGroupId field on the technicalChannel object (see technicalChannel (editorial-based))

  • API-based ingest – see Creating a technical channel

SSM offers APIs that allow you to tear down existing sessions on a per-account or per-device basis:
