Broadcast profanity delay and content sanitisation

Clean the screen. Before it airs.

Pro Cleaner holds your live programme in a delay buffer and gives the transmission operator the seconds needed to take out profanity, offensive language, and unwanted pictures—while the studio keeps rolling.

Operational confidence

Intervene before the viewer sees or hears it.

A delay does more than buy reaction time. It lets an intervention reach back into programme already held in the buffer, so the operator covers the incident—not only the seconds after the button press.

Dedicated operator hardware
01

Configurable delay

Hold the programme in a buffer sized for the operational risk and show the operator what is live versus what is leaving air.

02

Independent audio actions

Mute programme audio or substitute a 1 kHz reference tone over the configured interval.

03

Independent video actions

Blur, remove colour, or freeze the held picture while the studio source continues.

04

Flexible triggers

Use keyboard assignments, on-screen widgets, or a dedicated two-button panic panel.

05

Professional signal path

Work with qualified SDI, HDMI, NDI, and supported IP input and output workflows.

06

Compliance record

Write each intervention to a dated trigger log and export operational records to CSV.

Four-step workflow

Four stages, one signal path.

1

Ingest

Take a qualified baseband, NDI, or supported IP source while the operator preview stays live.

2

Delay

Hold the programme in a configurable buffer and show exactly what is leaving the system.

3

Intervene

Mute, tone, blur, desaturate, or freeze the held programme with timed triggers.

4

Transmit

Send the cleaned programme to an approved output and record every intervention.

Interactive simulator

Act before the incident reaches air.

Press Audio Panic or Video Panic and watch the intervention reach back into the held buffer. This simulator demonstrates the operator concept; it does not process real media.

Press a panic button. The seconds it covers are already in the buffer — the pre-roll reaches back before your press, so the incident is covered rather than your reaction time.
