Interactive Streaming For High-End Corporate Events – A Twebcast Case Study 

The Swedish B2B company Twebcast seamlessly integrates nanoStream Cloud into their event platform to run GDPR-compliant interactive events.  


When Twebcast approached nanocosmos 2021 to inquire about corporate streaming with seamless audience interaction, the following key elements were leading the conversation:  

  1. The live video streaming solution needed to be based on ultra-low latency as a minimum to allow smooth interaction with the audience without delay.  
  2. The integration into their event platform must be “white label” and GDPR-compliant. 

Leveraging nanoStream Cloud, Twebcast has run successful events for three years achieving sub-second global video delivery, and uninterrupted viewing experiences for the final viewers. We met with Gisela Grerup, CEO and cofounder of Twebcast to learn how our real-time video streaming solution enables interactive video streaming.

Gisela: “No matter what tools are used for an event, smooth interaction is a vital component that must be upheld for successful audience engagement. For the interaction between the stream and our video meeting tool Emeet, ultra-low latency is a must.

Combining features for a comprehensive solution 

TWEBCAST: Our goal is to offer a complete solution for virtual and hybrid events, where our customers get everything from participant registration to stream analytics and attendance reports. nanoStream Cloud is a white-label solution that allows us to integrate it into our setup via API. We can have ultra-low latency live streaming that is branded by our customers. 

With today’s requirement to communicate globally during some events, our job is to make sure employees can be reached anywhere. This means we must deal with different internet qualities, and potentially different time zones. To ensure interaction runs smoothly via streaming, we rely on transcoding and adaptive bitrate streaming features of nanoStream Cloud.
