Return Feed, Talkback and Cue: Three Live Signal Terms Explained
A plain-words guide to three terms heard in every control room, return feed, talkback and cue, and why each one matters when a live signal travels from venue to studio.

Why the vocabulary matters
Most misunderstandings on a live job do not come from faulty equipment. They come from two people using the same word for different things. A producer in a studio says 'give me a cue' and a camera operator hears something else entirely. Over the years I have coordinated deliveries between venues and broadcaster control rooms, and I have learned that a shared vocabulary saves more minutes than any piece of kit.
This note takes three terms that come up on almost every live signal job: return feed, talkback and cue. None of them is complicated, but each is easy to misuse when people are tired, cold or short of time. In mid autumn, with evening events starting early and light fading fast, outdoor shoots tend to run tight, which is exactly when loose language costs the most.
I will explain each term as a person on the job would use it, say where it sits in the chain from venue to studio, and note the usual ways it goes wrong. The aim is that a producer or organiser reading this can follow a signal conversation without feeling left out of it.
Return feed: seeing what the studio sees
A return feed is a signal sent back the other way. Your outgoing picture travels from the venue to the studio; the return feed brings the studio's programme output, or a clean reference picture, back to the venue. It is how a presenter standing in a car park can watch the bulletin they are about to join, and how an engineer confirms that what left the site is what arrived.
Without a return feed, a reporter is working blind. They cannot see when the studio cuts to them, cannot judge the pause before the answer, and cannot tell whether a graphic is covering their face. That is why we ask early whether a return is wanted, because it needs its own path and often its own monitor.
The common failure is assuming it comes free with the outgoing link. It does not. It uses separate capacity, and on a congested connection it can be the first thing to stutter. If the studio cannot supply one, say so before the day, not at the moment of the first live shot.
- It travels from studio to venue, opposite to the main picture
- It needs its own path and a monitor at the location
- Ask for it at booking, not on arrival
Talkback: the private conversation
Talkback is the private voice channel between the control room and the people on location. The audience never hears it. It lets a director tell a camera operator to widen the shot, lets a producer warn a reporter that they have thirty seconds, and lets a signal engineer say that the link is about to be switched.
The key point is that talkback is not the programme sound. People new to live work sometimes assume that anything said into a headset might go out, or the reverse, that the presenter can hear the studio simply because the studio can hear them. These are separate circuits, and keeping them separate is a matter of careful routing.
Good talkback is short. Names first, then the instruction, then silence. A crowded channel where four people speak at once is worse than none. We agree who holds the channel before the event, and we keep a second route, often a mobile call, in reserve in case the main one drops during the show.
- Heard only by crew, never by the audience
- Separate from the programme sound
- Agree who speaks and who listens beforehand
Cue: the moment that starts everything
A cue is the signal to begin. It might be a spoken instruction on talkback, a count in the ear, a light, or a hand signal at the edge of frame. What matters is that the person acting on it knows exactly which cue belongs to them and when it is valid.
The confusion arises because 'cue' is used for several things. There is the cue to start recording, the cue for a reporter to speak, and the cue to cut away. A good routine names each one. 'Stand by' means be ready; 'go' means act now. Mixing these is how a presenter ends up speaking over the end of a package.
Delay makes it harder still. A signal travelling by satellite arrives noticeably later than one on fibre, so a spoken cue from the studio may reach the venue after the moment has passed. Experienced crews cue on a count from the control room and build in the known delay, rather than waiting to hear the programme.
- Stand by means be ready, go means act now
- Different cues for recording, speaking and cutting away
- Allow for delay on satellite and long internet paths
How the three fit together on a real job
Picture a news insert from an outdoor location on a cold evening. The camera picture and sound go out to the studio. The return feed shows the reporter the bulletin in progress. Talkback tells the crew that the item is two minutes away. Then a count, ending in a clear go, is the cue that puts the reporter on air.
Each term describes a separate piece of the same chain, and each can fail independently. A picture can be perfect while talkback is dead, or the return can be fine while the cue arrives late. Treating them as one 'communications problem' makes faults hard to find; treating them separately makes them quick to isolate.
That is the practical habit we try to pass on to clients. When something is wrong, name which of the three it is. The engineer can then go straight to the right circuit instead of asking you to describe a feeling that something is off.
What to ask your signal team before the day
You do not need to master the equipment, but a few direct questions will tell you whether the plan is sound. Ask whether a return feed will be provided and on what path. Ask who is on talkback and what the fallback is if it fails. Ask what the delay will be, and how cues will be given to allow for it.
These questions also help the studio. A control room that knows the venue has a return and a spare talkback route can plan its running order with confidence, instead of leaving room for the unexpected. Producers who ask them tend to have calmer broadcasts.
If an answer sounds vague, that is useful information in itself. A team that has done this before will answer plainly, with names and numbers, and will usually have a written note of the arrangement ready to share.
- Is a return feed included, and by what route?
- Who is on talkback, and what is the backup?
- What delay should we expect, and how will cues allow for it?
Return feed, talkback and cue are small words that carry a lot of weight on a live job. Knowing what each one means, and keeping them apart, makes faults easier to find and conversations easier to follow. If you are planning a broadcast and want to talk through how these would work at your venue, the team at commonra is happy to go through it in plain terms before the day.
