Created by RealSprint in Sweden, DALS stands for Dynamic Adaptive Live Streaming. It is the world’s only live streaming technology that delivers stable ultra low latency to any platform, including mobile browsers such as iOS Safari. Currently powering over 100 brands globally and available as a service or software for on-premise deployment.

To create an outstanding experience for your users the quality of service needs to be consistent across the board. Speed, stability, compatibility - they are all fundamental for today's products. DALS has got you covered.



DALS provides a fully configurable buffer to maintain a latency range of your choice. Due to its unique architecture, latencies in the second-range glass to glass are no problem. Or sub-second if that's what you need. Typical use cases range from 500ms to 1,5s.


stability & SYNC

Every moment matters. That's why our player switches bitrates before congestions occur. Network conditions are continuously analyzed and the stream is adapted to maintain stability. No viewer falls behind, even on a non-perfect 3G/4G connection.



DALS runs in any browser - desktop or mobile. That includes iOS Safari. No plugins, no apps needed. It is purely based on HTML5 and JavaScript. And of course it runs in apps as well - mobile and OTT.

Horse racing

The never-ending action of horse racing has gathered a large number of devout followers and betters. As the digital transformation keeps changing how we consume entertainment and interact with content, the live streamed events need to be served with minimal latency, and at a high video quality. We're working closely with industry leaders in horse racing to bring the next generation of user experience to the market, and keep it evolving.

Sports betting

Nothing gets viewers immersed in an ongoing sports event quite like betting. Whether the wagers are made before kick-off or users are betting in-game, excitement is maximized when the stakes are high. Live streams using competing technologies such as HLS / DASH fail on either latency, stability or scalability. DALS brings the user within 1 second of the action.

Online casino

The world's leading live casino, created by Net Entertainment, is powered by DALS. The product runs in desktop- and mobile web browsers, and has been in production since 2016. Several key features of DALS are implemented, such as frame synchronized cue points and embedded interactive layers. RealSprint works closely with Net Entertainment to develop the high-end product and stay ahead of the competition.

Online Auctions

There is no room for compromise when it comes to streaming live auctions. Hundreds of users that connect simultaneously to an auction house need access to the content with high demands on stability, often connecting through mobile browsers on lossy networks.

Second screen

With the transformation of traditional television, second screen experiences are increasingly forming to enable interactivity and drive viewer immersion. Be it a live racing situation, game show or interactive story, any second screen application requires high quality video, synchronization and frame-synchronized app triggers.

Public safety

Both in urban and rural areas, technology is changing how emergencies are handled. Firefighters, law enforcement, experts and volunteers are working together in new ways to counter urgent threats to the public. DALS enables ultra low latency distribution of drone streams, body cams and command center video while making the content available in a secure way across any platform. Sharing of live streams across different organizations helps coordinate efforts in a completely new way.
