coralbay.tv brings AI captioning and smarter IP live input switching to NAB

The schedule-aware live input switching in coralPlay tackles a real inefficiency in IP playout: decoding every incoming source simultaneously wastes compute resources. By decoding only scheduled sources in advance, coralbay.tv directly reduces cloud compute costs for multi-channel operators. coralCaption enters a market where multiple vendors launched AI captioning products at the same show, making its no-decode insertion approach a potential differentiator for broadcasters concerned about latency in live transport streams. Watch whether coralbay.tv's microservices architecture — deployable in any cloud or on-premises — attracts broadcasters migrating from hardware-based captioning and playout systems.

coralCaption was developed in collaboration with Red Bee Media, as announced on March 20, 2024 per coralbay.tv. Red Bee operates its own ARC (Automatic Realtime Captioning) platform, which it reports achieves 98%+ accuracy at less than half the cost of human captioning. At Australian broadcaster Network 10, Red Bee's AI captioning workflows reduced per-hour captioning costs by 21% over 12 months, with over half of all captioning volumes created using automation and 99%+ live accuracy based on NER quality assessment, per Red Bee Media's website, 2024.

NAB 2024 featured a cluster of AI captioning launches alongside coralbay.tv's offering. AI-Media introduced LEXI DR (Disaster Recovery), targeting 99.99% caption uptime, and LEXI Recorded, claiming 98%+ accuracy for recorded content, per GlobeNewswire, April 8, 2024. VITAC, owned by Verbit, debuted Captivate, an AI-powered captioning engine with a Dynamic Domain Dictionary for domain-specific terminology, per Sports Video Group, April 12, 2024. Amira Labs also demonstrated live multilingual AI captioning with sub-1-second latency at the show, per Streaming Media Producer, April 2024.

Regulatory pressure on caption quality is intensifying. The FCC released a document on October 18, 2024 titled "The Use of Artificial Intelligence to Caption Live Video Programming," and in July 2024 proposed amendments to its closed captioning rules (FCC 24-80), per the FCC website. These moves signal growing scrutiny of AI-generated caption quality for live programming, where accuracy, synchronicity, completeness, and placement standards are already codified under 47 CFR § 79.1.

coralCaption initially supports Teletext and OP47 subtitle formats, with plans to add 608/708 captioning and DVB bitmaps in future releases, per coralbay.tv, March 2024. This limits near-term adoption to broadcasters using those standards — primarily European and UK markets — while the planned 608/708 support would open the product to North American broadcasters subject to FCC captioning rules.
