Message format – EPG update
Overview
OpenTV Platform can be configured to send notifications to clients to let them know that there have been changes to EPG metadata.
These changes include:
Changes to BTV (live) metadata – for example, a change to a description or episode name
Rescheduling of live events – for example, the extension of a football match that has gone into extra time, and the rearrangement of subsequent programmes
EPG change notifications do not include the details of the changes. They are just notifications.
The client must call Metadata Server (MDS) or Content Discovery Facade to get the updated event details.
