What is Over The Network (OTN)?

Over The Network (OTN) refers to the remote delivery of firmware updates to smart TVs and connected devices using an internet connection. It allows manufacturers to push new features, performance improvements, or security patches directly to TVs—without user intervention.

In the streaming TV ecosystem, OTN updates ensure that devices stay compatible with the latest apps, content formats, and ad technologies.

How OTN Works in Streaming Devices

When a TV is connected to the internet, the manufacturer can send firmware updates “over the network.” These updates are downloaded and installed in the background or during scheduled maintenance windows. For example, a new version of the TV’s software might include improvements to video decoding, ad rendering, or channel discovery.

OTN updates may also fix bugs, enhance UI responsiveness, or improve content protection measures like DRM.

Why OTN Matters for Streaming TV

OTN plays a key role in keeping streaming experiences consistent across millions of devices. For publishers, it ensures content plays smoothly and reaches viewers as intended. For platform partners like Wurl, it helps maintain support for new ad formats, content standards, and delivery protocols without needing manual updates from users.

By keeping firmware current, OTN enables better performance, improved viewer experiences, and longer device lifespans—all essential for scaling streaming TV globally.

Conclusion

Over The Network (OTN) is how smart TVs and connected devices receive essential firmware updates remotely. It keeps streaming platforms compatible, secure, and up to date—powering seamless viewing experiences for millions of households worldwide.
