SCTE-35 markers in the output signal at certain moments in time trigger devices which are listening to the signal when a potential advertisement or programme is scheduled. When the scheduled time arrives, the splicer device switches over to locally inserted advertising or content. This increases the flexibility for improved localized advertisement creating income sources for channels and operators alike. GRIDSHOT® has integrated the SCTE-35 into the playout solution. Our scheduling application is built to facilitate insertion of these SCTE-35 markers.
