How SonyLIV Powers Real-Time Interactivity for Millions of Viewers

SonyLIV, the popular OTT platform from Sony Pictures Networks India, is setting a new standard for interactive TV experiences. From enabling live audience participation in Kaun Banega Crorepati (KBC) to delivering up-to-the-second sports scores to millions of fans, SonyLIV is bringing broadcast-scale interactivity to the digital age — and it’s doing it with Lightstreamer.

At the core of these real-time features is a technical challenge: how do you deliver synchronized data to hundreds of thousands of users at once, with minimal delay, during a live event? For SonyLIV, the answer came in the form of Lightstreamer’s enterprise-grade real-time messaging engine.

“With a single instance, we were able to serve around 500K users,” shared a spokesperson from the SonyLIV Technology team.

This level of scale was critical for KBC Play Along, where viewers participate in real time alongside the live game show. Lightstreamer ensures that questions, answer options, waiting screens, and score updates reach every user simultaneously, creating a fair and fully immersive experience — even under massive load.

SonyLIV also uses Lightstreamer to power real-time scorecards for football and cricket, and is planning to extend its use to other formats, including live tennis. The team evaluated other technologies but found Lightstreamer best suited for their needs:

“While alternatives like Socket.IO or Firebase might suit basic real-time needs, Lightstreamer provides a complete, enterprise-grade real-time messaging solution with superior performance, reliability, and scalability.”

For complex, broadcast-heavy scenarios where uptime, synchronization, and scalability are non-negotiable, Lightstreamer proved to be the right fit.
