Getting ready: Set the ad avail mode
You must set the mode for SCTE 35 handling. The blanking, blackout, and manifest decoration features of MediaLive work different depending on the mode.
To set the ad avail mode
-
In the channel that you are creating, in the navigation pane, choose General settings. Choose Avail configuration.

Complete the fields as follows:
Field Description Avail settings If your organization has a POIS server that handles decisions about SCTE 35 messages, then choose ESAM and read POIS signal conditioning now.
Otherwise, choose SCTE-35 splice insert or SCTE-35 time signal apos. The mode to choose depends on the message types that you expect to be present in the source, and on how you want to handle those messages. See the table later on this page.Ad avail offset Set a value, if desired. For details about a field on the MediaLive console, choose the Info link next to the field. web_delivery_allowed_flag Typically, leave as Follow.

This table identifies how the two different ad avail modes work. It identifies the combinations of message type and segmentation type that each mode considers as an ad avail. Note that in both modes, MediaLive looks at both splice insert messages and time signal messages.
To read this table, find a message type in the first column and a segmentation type in the second column. The third and fourth columns specify whether MediaLive treats this message combination as an ad avail when the mode is splice insert mode and when the mode is timesignal APOS mode.
