Managing playback sessions

Overview

OpenTV Video 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 account-level session limits in account profiles in OpCon.

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 Adding Technical channels.
• At ingest:
  • File-based ingest – see the sessionGroupId field on the technicalChannel object (editorial-based, technical-based)
  • API-based ingest – see Creating a technical channel

Channel group session limits apply globally. That is, you cannot specify different channel group session limits for different account profiles.

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