Configuring a Channel to Process SCTE104 Messages
The video signal to the SDI video card in the playout server can contain SCTE 104 messages
(also known as digital cue tones). iTX can detect such messages and respond to them to
start the playout of a sequence that is on hold in a schedule or end a sequence iTX is
currently playing. SCTE refer to the time space provided by broadcasters to trigger these
sequences as the “avail”. Output Server 2 gives users the ability to enable and disable
individual SCTE 104 features independently, depending on their requirements.
