These specifications define specific means for enabling and managing the delivery of alternative content in TV services that are delivered over IP transport.
This group contains two specifications:
- Event Scheduling and Notification Interface (ESNI) - defines a functional method for allowing programmers to notify cable operators of upcoming alternative content (e.g., regional sports blackouts), which will require a subscriber's device to access alternate content during a specific time frame. The Event Scheduling and Notification Interface (ESNI) is a web interface facilitating the notification of these events.
- Event Signaling and Management API (ESAM) specification - details the APIs for processing real-time signals (e.g., SCTE 35 and others) and enables real-time manifest generation. These APIs are used by MSOs to recognize and respond to network signaling and create downstream client signaling or other manifest data in support of ad insertion, alternative content, and other related uses.
