SCTE35 / 104 Inserter & Decoder CueOn
Ad splicing,
done in
software.
CueOn inserts and decodes frame-accurate ad cues on standard SDI — no dedicated splicer hardware. Insert the cue, then verify it downstream, in one application.
Why CueOn
Three things a dedicated splicer makes harder than it should be.
01
Runs as software over generic SDI I/O. Get frame-accurate SCTE insertion at a fraction of a dedicated splicer's cost — and without the rack space.
No dedicated hardware
02
CueOn re-receives and decodes your own output on a second path, so you confirm the cue landed correctly — send-to-receive — instead of trusting it did.
Verify what you sent
03
Built for station handoff
Pre-roll countdown fires cues ahead of arrival time, matching the inter-station timing conventions real playout workflows depend on.
Insert, monitor, and rule on cues — from one GUI.
Live pass-through inserter
Multiplex cues without touching the program
The on-air SDI program passes straight through to output while SCTE-104 is multiplexed into VANC on cue fire. The inserted line is then received and decoded on a separate path for closed-loop monitoring.
Pre-roll countdown
Fire cues ahead of arrival
Schedule timecode is treated as the splice arrival point; cues are sent a configurable pre-roll ahead (default 4 s; 3 / 5 s and others). This maps to SCTE-104 pre_roll_time, and the timeline shows the send-to-arrival gap plus a NEXT ARRIVAL countdown.
GPIO integration
Tally out, trigger in
Supported USB GPIO units drive CUE OUT / CUE IN relay (tally) outputs and isolated DI trigger inputs. Output and input channels are separated by terminal space, with reservation and conflict warnings so units can share a board safely. Channel maps are set and saved from the GUI.
Dual confirmation monitors
See before and after, side by side
The GUI places a send-side monitor (SDI 3 IN) next to a receive-side monitor (SDI 4 IN), so you compare the program before and after insertion, frame by frame (up to ~30 fps).
Rule-based insertion
Decide per station, per mode
Hot-reloadable rules evaluate insert-all, pass-all, or selective insertion. Each cue's verdict — with its reason — is shown as an ACT / PASS badge in the decoder pane.
Format & timing
Speaks the formats your plant already uses
SCTE-35 as XML / Base64 / Hex with a verify view, output over SDI VANC, MPEG-TS (configurable PID), or SRT, and TC↔PTS conversion across the common broadcast rates.
Signal Flow
From inserter to decoder, on one machine.
CueOn passes the live program through while inserting SCTE-104 into VANC, then loops the output back into its own decoder to prove the cue is present.
