        Value (string) –
        
        For SCTE35_ENHANCED output, defines a value. MediaTailor; takes this value, and its associated key, and generates the key/value pair within the ``EXT-X-ASSET``tag. If you specify a value, you must also specify a corresponding key.
    - MessageType (string) –
      
      The SCTE-35 ad insertion type. Accepted value: SPLICE_INSERT, TIME_SIGNAL.
    - OffsetMillis (integer) –

    - SpliceInsertMessage (dict) –
      
      This defines the SCTE-35 splice_insert() message inserted around the ad. For information about using splice_insert(), see the SCTE-35 specficiaiton, section 9.7.3.1.
      - AvailNum (integer) –
        
        This is written to splice_insert.avail_num, as defined in section 9.7.3.1 of the SCTE-35 specification. The default value is 0. Values must be between 0 and 256, inclusive.
      - AvailsExpected (integer) –
        
        This is written to splice_insert.avails_expected, as defined in section 9.7.3.1 of the SCTE-35 specification. The default value is 0. Values must be between 0 and 256, inclusive.
      - SpliceEventId (integer) –
        
        This is written to splice_insert.splice_event_id, as defined in section 9.7.3.1 of the SCTE-35 specification. The default value is 1.
      - UniqueProgramId (integer) –
        
        This is written to splice_insert.unique_program_id, as defined in section 9.7.3.1 of the SCTE-35 specification. The default value is 0. Values must be between 0 and 256, inclusive.
    - TimeSignalMessage (dict) –
      
      Defines the SCTE-35 time_signal message inserted around the ad.
      
      Programs on a channel’s schedule can be configured with one or more ad breaks. You can attach a splice_insert SCTE-35 message to the ad break. This message provides basic metadata about the ad break.
      
      See section 9.7.4 of the 2022 SCTE-35 specification for more information.
      - SegmentationDescriptors (list) –
        
        The configurations for the SCTE-35 segmentation_descriptor message(s) sent with the time_signal message.
        
        (dict) –
        
        The segmentation_descriptor message can contain advanced metadata fields, like content identifiers, to convey a wide range of information about the ad break. MediaTailor writes the ad metadata in the egress manifest as part of the EXT-X-DATERANGE or EventStream ad marker’s SCTE-35 data.
        
        segmentation_descriptor messages must be sent with the time_signal message type.
