In order to interoperate with MBMS, the HLS client should be MBMS-aware. This allows it to take best advantage of broadcast content and unicast content when and where broadcast is not available.
The HLS Master Playlist of an asset pertains equally to both the broadcast and independent unicast availability of a media asset. Generally only a small subset of HLS Media Playlists published in a Master Playlist will be available via an MBMS broadcast. This subset is typically chosen to satisfy the union of all supported UE media decoder compatibilities. A shared Master Playlist is required to support the unicast fallback described in this clause.
