Release: Callaba 8.4
Multiview, or browser-based multiview, is a monitoring interface that displays several live video sources on a single screen. Operators can watch streams, check bitrate and resolution, hear audio, and manage failover — all without dedicated multiview hardware.
In live production, this matters because monitoring is not only about seeing pictures. A useful multiview should help you understand whether each source is alive, whether the transport is stable, which route is active, and what to do when the main feed starts to degrade.
Quick answer: what is multiview?
Multiview is a way to watch and monitor several live video sources on one screen at the same time. In Callaba, multiview runs in the browser, so you can send SRT streams to the cloud, place them on tiles, watch them in real time, and control main / backup failover from the same board.
What multiview means in live production
At the basic level, multiview means displaying several sources in a single screen layout. That idea has been around for a long time in control rooms and broadcast operations. What changed is the workflow around it.
Today, teams do not only want to see several sources. They also want to:
- watch incoming streams in real time,
- reduce the number of local monitors and local decode paths,
- check bitrate and codec information while working,
- monitor audio inside each tile,
- see connection and failover state,
- switch between main and backup when something goes wrong.
That is why modern multiview is not just a wall of pictures. It is a control surface for live monitoring.
Why browser-based multiview matters
Traditional multiview setups often depend on local hardware, extra monitors, and local decode infrastructure. That still works, but it creates friction. Someone has to keep that environment running, scale it, and maintain it every time the workflow changes.
A browser-based multiview changes the model. Instead of pulling every feed back into your local machine, you can send SRT streams to the cloud and monitor them there. This reduces pressure on local infrastructure and makes it easier to share the same board across operators, engineers, and producers.
In practical terms, this means:
- less local hardware to manage,
- easier remote collaboration,
- faster setup for live events,
- one place to see monitoring and failover behavior,
- a cleaner path from contribution to final delivery.
Traditional hardware multiview vs cloud browser multiview
Hardware multiview is still useful in many control rooms. But cloud and remote production workflows often need something more flexible: browser access, SRT support, remote monitoring, and integration with routing or failover logic.
| Criteria | Traditional hardware multiview | Callaba browser-based multiview |
|---|---|---|
| Hardware cost | Requires dedicated devices, displays, cabling, and local installation. | Runs in the browser after streams are received by Callaba. |
| Remote access | Usually tied to the physical control room or local network. | Can be opened by operators from a browser when the deployment is configured for remote access. |
| Scalability | Scaling often means more hardware, more cables, and more local setup. | Boards and inputs can be managed as part of the cloud workflow. |
| SRT workflow | Often needs additional conversion or routing before monitoring. | Designed around SRT contribution and browser monitoring. |
| Failover awareness | Usually handled in a separate routing or switching system. | Main / backup route state can be visible inside the multiview board. |
How Callaba multiview works
I built Callaba multiview around a simple production need: send your live SRT feeds into the cloud, place them on a board, and keep control over what happens next.
Instead of treating monitoring as a separate local problem, Callaba makes it part of the same cloud workflow that already receives, routes, and protects your live feeds.
- SRT encoder: cameras, encoders, remote venues, or production tools send live feeds over SRT.
- Callaba SRT gateway: Callaba receives the contribution feeds in the cloud and makes them available for monitoring and routing.
- Multiview board: operators open the board in a browser, choose a tile layout, and monitor live streams with metadata such as resolution, codec, bitrate, and audio state.
- Failover switcher: main and backup routes can be observed and controlled from the same operational surface.
- Destinations: the selected output can continue to restreaming, browser playback, recording, CDN delivery, or other downstream workflows.
Technical capabilities at a glance
Callaba multiview is designed for real-time live monitoring, but the exact behavior depends on deployment, source settings, browser conditions, and network path. These are the practical capabilities visible in the current workflow.
Interface walkthrough
1. Join screen and board access
The first screen is intentionally simple. It gives you a board link, a copy button, and a clear Join to Multiview action. This is useful because sharing the monitoring board should not require complicated setup every time. Operators can open the same board quickly and start monitoring the live workflow.
2. Layout selection and tile-based monitoring
Once inside the board, the layout selector becomes one of the most important controls. In the example shown here, the board is set to 9 tiles. This matters because a multiview board is only useful when you can quickly adjust how many inputs you want to see at the same time.
Some workflows need only a few critical feeds. Others need a wider board for contribution monitoring. A flexible tile layout is what makes multiview practical instead of static.
3. Inputs panel
On the left side, the Inputs panel shows the available sources. In the example board, you can already see named inputs such as Stream-1, BACKUP LINE, and Stream-3. This is important because the multiview is not only showing pictures. It is helping you understand which source is which and how each source fits into the board.
The inputs list also makes it easier to manage larger boards because the operator can identify sources before assigning or reassigning them to a tile.
4. Live tile overlays
Each active tile contains much more than a picture. The tiles in the screenshot show exactly the kind of live data operators need:
- stream name,
- resolution,
- protocol and codec,
- bitrate in kbps,
- audio level controls,
- small tile actions for management.
This is a major difference between a basic “many videos on one page” view and a real monitoring board. The tile becomes a live status surface, not just a preview window.
5. Empty tiles for board expansion
The empty slots with Add stream buttons matter too. They show that the board is not fixed. You can expand the working view by adding more sources to open positions. In real operations, this makes the board faster to adapt during setup, rehearsal, or live troubleshooting.
6. Connection log
On the right side, the Connection Log gives immediate visibility into what is connected. It includes:
- search for filtering sources,
- connection state per stream,
- time-based log entries,
- clear logs action,
- route status visibility.
This is the kind of feature that becomes valuable during real incidents. If something is wrong, operators need more than a black tile. They need to know whether the source connected, when it connected, and which route is currently active.
7. Built-in failover controls
One of the most useful parts of this interface is the Failover route block shown inside the board view. In the example, you can see a route switch between main and backup. That means the multiview is not isolated from routing logic. The operator can understand and control source behavior from the same place they monitor the feeds.
Typical workflow: encoder to destinations
Here is the basic production path that makes this feature valuable:
- SRT encoder: your source sends the live stream.
- Callaba SRT gateway: the stream enters the cloud workflow.
- Multiview board: operators see the feeds in the browser and monitor them in real time.
- Failover switcher: main and backup paths can be controlled or observed from the same environment.
- Many destinations: the final output can continue toward restreaming, browser playback, recording, or other delivery paths.
This is why multiview should not be treated as a cosmetic feature. It sits in the middle of a larger live workflow and helps the operator keep control over it.
Failover control inside multiview
Monitoring and failover belong together. If you can see a stream degrade, you should also be able to understand what the system is doing about it.
In Callaba, multiview helps with that by exposing the route state directly in the board. This gives two practical benefits:
- you can monitor main and backup inputs in the same board,
- you can understand whether the failover route is currently on main or backup.
For real live production, this matters a lot. Operators do not want to switch between one monitoring interface and a separate routing panel every time they need to confirm source state.
If your workflow already includes protected contribution, this also fits naturally with a broader SRT path. You can start with SRT contribution, bring it into a Callaba SRT server, then monitor it through multiview and continue to downstream distribution.
Callaba vs other multiview approaches
Different multiview tools solve different jobs. Some are built for local production software, some for hardware monitoring, and some for cloud media pipelines. Callaba focuses on browser-based SRT monitoring with failover awareness.
| Approach | Best for | Main limitation | Where Callaba is different |
|---|---|---|---|
| OBS or local software layouts | Simple local monitoring and production scenes. | The local machine still carries the decode and monitoring load. | Callaba moves monitoring into the browser after cloud ingest. |
| vMix multiview / local production tools | Local production rooms where vMix is the main switching surface. | Monitoring remains close to the local production system. | Callaba is useful when feeds arrive over SRT and need cloud monitoring or remote access. |
| Hardware multiviewers | Broadcast facilities with SDI/HDMI monitoring needs. | Requires physical hardware, cabling, and local display infrastructure. | Callaba is browser-based and fits SRT cloud contribution workflows. |
| Generic cloud monitoring | Checking stream availability or output health. | May not be connected to failover control or input-level SRT monitoring. | Callaba combines SRT previews, tile layout, connection log, and failover route state. |
Use cases
Remote production
When sources arrive from different locations, a browser-based multiview helps the team see all important feeds without rebuilding a local wall of monitors.
Backup and redundancy monitoring
When you have a main line and a backup line, it helps to keep both visible in the same board and confirm the active failover route in real time.
Cloud-based control rooms
If more of the workflow is moving into the cloud, the monitoring surface should move there too. Multiview becomes part of the cloud control room.
Multi-stream operations
Teams handling several contribution feeds can use one board to track them, keep layouts clean, and route attention to the feeds that matter most.
Security cameras and CCTV-style monitoring
Multiview can also be useful when camera feeds need to be watched together. The practical requirement is that the camera or gateway must send a supported stream into the workflow.
How to start with Callaba multiview
- Create or open your Callaba environment.
- Add one or more incoming SRT streams.
- Open the multiview board and choose the tile layout you need.
- Place your input streams on the board tiles.
- Use the connection log and route controls to monitor live behavior and failover state.

Why this matters operationally
The main reason I like this workflow is simple: it removes noise from live operations. When monitoring, routing awareness, and failover visibility live in one browser board, the team spends less time stitching tools together and more time staying in control of the stream.
That is what good multiview should do. It should not just show more pictures. It should reduce operational friction.
FAQ
What is multiview?
Multiview is a way to monitor multiple live video sources on one screen at the same time. In modern workflows, it often includes layout control, status visibility, and audio monitoring.
What is browser-based multiview?
Browser-based multiview means you can open the monitoring board in a web browser instead of relying only on local hardware or dedicated local monitoring systems.
Can I monitor SRT streams in multiview?
Yes. In Callaba, you can send SRT streams to the cloud and monitor them in the multiview board in real time.
Why is multiview useful for live production?
It helps operators watch several sources at once, compare stream behavior, hear audio, and react faster when one source degrades or disconnects.
Can multiview help with failover?
Yes. In Callaba, the board can show route state and help the operator monitor main and backup paths in the same interface.
What is the advantage of cloud multiview over local-only monitoring?
Cloud multiview reduces local infrastructure load and makes it easier to share the same monitoring board across operators and locations.
How many streams can I place on a board?
That depends on the selected layout and your workflow. The example shown here uses a 9-tile board.
Is multiview only for broadcasters?
No. It is useful for broadcasters, live event teams, remote production workflows, security-style camera monitoring, and anyone who needs to monitor multiple live sources in a clean and controlled way.
Multiview vs picture-in-picture: what is the difference?
Picture-in-picture usually means one small video over another main video. Multiview means several sources are arranged together in a monitoring layout, often with labels, audio controls, stream metadata, and operational status.
Can I use multiview for security cameras?
Yes, if the camera feeds can be brought into the workflow in a supported streaming format. For security or CCTV-style use cases, the key questions are protocol support, latency, access control, and how many feeds need to be monitored at the same time.
What is the difference between multiview and matrix switching?
Multiview is mainly for monitoring several sources on one screen. Matrix switching is for routing signals from inputs to outputs. In live production, both can work together: multiview helps operators see sources, while routing or switching decides which source goes where.
Final practical rule
A useful multiview is not only a multi-screen view. It is a monitoring layer for real production workflows. If it lets you see your SRT streams in the browser, choose tile layouts, understand connection state, and keep failover visible, it is doing the real job.
