Getting ready: Set the ad avail mode

To set the ad avail mode

1. In the channel that you are creating, in the navigation pane, choose General settings. Choose Avail configuration.

2. 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. For information about these fields, see Ad avail blanking restriction flags.
   no_regional_blackout_flag
   SCTE 35 segmentation scope	This field affects segment breaks in the video output encodes, in output groups that contain transport streams. In other words, in HLS, MediaPackage, Multiplex, and UDP output groups. This field doesn't affect output groups that don't contain transport streams. The field controls how segmentation in these TS output groups is affected by SCTE 35 messages. The field is particularly important if some of these TS output groups have SCTE 35 passthrough enabled (they are SCTE 35-enabled output groups), and some don't have it enabled. Choose the desired appropriate value: ALL_OUTPUT_GROUPS: MediaLive inserts the SCTE 35-triggered segment break in all output groups. In non-SCTE 35-enabled output groups, this behavior might result in unnecessary segment breaks or in inconsistent segment break lengths. SCTE35_ENABLED_OUTPUT_GROUPS: MediaLive inserts the SCTE 35-triggered segment break only in SCTE 35-enabled output groups. This is the recommended value, because it reduces unnecessary segment breaks in output groups that aren't SCTE 35 enabled.
