ARD & RBB Text

Seamless Subtitle Integration to Enhance Live Stream Accessibility

Overview: ARD and RBB Text, two renowned German broadcasters, faced the challenge of integrating subtitles into their live streams without overhauling their existing infrastructure. With a limited budget and a need to comply with anticipated regulations, they sought a cost-effective yet efficient solution to make their content more accessible.

Details: The project involved creating a live subtitle inserter that could seamlessly interface with their existing subtitle/caption generation tools. The primary challenge was to integrate this functionality into their current OTT streams without necessitating expensive upgrades or replacements of their existing encoders. The solution needed to be resource-efficient, avoiding any additional load on their Content Delivery Network (CDN) or the need for transcoding.

Working with Motion Spell

Motion Spell was tasked with developing a solution that met these stringent requirements. The team at Motion Spell approached this challenge by focusing on creating a lightweight and efficient subtitle inserter. This tool, now offered by Motion Spell as the Abstract Conformance Framework, was designed to work in harmony with the broadcasters' current systems, ensuring that the integration was smooth and did not disrupt their existing workflows. The final solution delivered by Motion Spell was notable for its minimalistic approach – it required no transcoding and did not add any extra burden on the CDN. This approach not only met the budgetary constraints but also expanded the accessibility of the broadcasters' content, making it available to a wider audience without compromising on quality or performance.
