Eligible messages and streams

Elemental Live can extract SCTE-35 messages and SCTE-104 messages from input sources.

The following table specifies the sources (and their corresponding input types) that Elemental Live supports for each message type.

Message type	Source type	Elemental Live Input type
SCTE-35	HLS	HLS network input
	MPTS over RTP or UDP	Network input
	Transport stream	Secure Reliable Transport (SRT)
	Transport stream over RTP or UDP	Network input
	Transport stream over RTP with SMPTE 2022-7 redundancy	SMPTE 2022-7 network input
SCTE-104	SDI	An SDI or Quadrant interface
	SDI	Interleave 4K (HD-2SI)
	SMPTE 2110-04 over RTP or UDP	SMPTE 2110

Note

SCTE-104 messages are converted to SCTE-35 messages early in the processing, so this guide uses “SCTE-35 messages” to refer to both SCTE-35 messages and SCTE-104 messages.
