Case Study: S4C boosts accessible, bilingual CTV delivery with FX Digital

S4C cuts CTV rollout time from 18 months to 2 months with FX Digital

S4C, the Welsh public service broadcaster, faced a critical challenge when its legacy Connected TV app failed certification, excluding it from key platforms like Freeview and breaching its public service obligations. Partnering with FX Digital, S4C needed a future-proof solution to modernize its OTT strategy, overcome device fragmentation, and meet stringent bilingual and accessibility standards without sacrificing reach or compliance.

FX Digital rebuilt the CTV suite from the ground up using the LightningJS framework, creating a unified, modular codebase deployed across six platforms. This solution delivered the first bilingual audio support on Freeview, achieved GDPR compliance, and unlocked new ad revenue on previously unsupported devices. The results for S4C included successful certification across major platforms, a 70% automated test coverage ensuring reliability, and high praise from the client, setting a new benchmark for accessible CTV delivery.
