Understand how Viaplay broadcasts work
Learn how a broadcast is delivered to your device and why picture quality may vary.
How picture quality adjusts automatically
Viaplay uses a technology called Adaptive Bit Rate. This means that video quality is automatically adjusted based on:
- your internet speed
- the stability of your internet connection
- the capacity of the device you are using
If the internet connection is stable, the content is shown in higher quality.
If the internet connection varies, the quality may be temporarily lowered to avoid interruptions. This may be noticed as lower resolution or buffering during the broadcast.
The adjustment happens automatically throughout playback.
How a broadcast is delivered to your device
When you start a movie, series, or sports broadcast, the following happens:
- Your device sends a request to play the content through your internet connection.
- The request is received by a CDN (Content Delivery Network).
- The CDN identifies your device and your current internet speed.
- The CDN selects the server that is technically best suited to deliver the content.
- The content is sent from the selected server to your device.
- Adaptive Bit Rate continuously adjusts the video quality during playback.
A CDN is a network of servers set up to deliver content quickly and reliably. If one server is heavily loaded or stops working, traffic is automatically redirected to another available server.
This structure reduces the risk of interruptions and allows the broadcast to continue even if demand changes.
