This section describes how AWS Elemental MediaTailor manages tags in the personalized output manifest.
EXT-X-CUE tags
MediaTailor replaces EXT-X-CUE-OUT
, EXT-X-CUE-OUT-CONT
,
and EXT-X-CUE-IN
tags in the input manifest with
EXT-X-DISCONTINUITY
tags in the output manifest. The
DISCONTINUITY
tags mark the following boundaries:
-
Where the main content transitions to an ad
-
Where one ad transitions to another ad
-
Where an ad transitions back to the main content
EXT-X-DATERANGE tags
MediaTailor passes through EXT-X-DATERANGE
tags from the input manifest
to the output manifest. MediaTailor also inserts EXT-X-DISCONTINUITY
tags
that correspond to the DATERANGE
tags. The DISCONTINUITY
tags
mark the following boundaries:
-
Where the main content transitions to an ad
-
Where one ad transitions to another ad
-
Where an ad transitions back to the main content
EXT-X-KEY tags
MediaTailor passes through EXT-X-KEY
tags from the input manifest.
These tags indicate that the main content is encrypted. Since ads aren't encrypted,
MediaTailor inserts EXT-X-KEY:METHOD=NONE
at the start of an ad avail. When
playback returns to the main content, MediaTailor re-enables encryption by inserting the
EXT-X-KEY
tag with the METHOD
value defined as the encryption
type.
Unrecognized tags
MediaTailor passes through all unknown and custom tags from the input manifest to the output manifest.
