ENC81
AI-assisted Closed Caption encoder
Live captionsin 1 second.
ENC81 transcribes and encodes captions in real time with ultra-low latency — for live broadcasts, hybrid events, and on-demand video. Accessibility and global reach, without compromising delivery quality.
Make your live programmingaccessible and inclusive — 24 hours a day, 7 days a week.
ENC81 encodes Closed Caption in CEA-608 and CEA-708 formats, integrating them directly into the H.264 or H.265 video stream according to the ATSC A/53 standard. Operating autonomously or integrated with the IFN100, it offers full compatibility with digital players, OTT platforms, receivers, and televisions.
Core technology
ASR. Translation.
Broadcast.
01
Automatic Speech Recognition
ASR technology transcribes audio in real time with latency of just 1 second. Native support for Brazilian Portuguese, English, and LATAM Spanish — with a customizable vocabulary for technical terms and jargon.
02
Automatic Translation
Beyond transcription, ENC81 automatically translates content into multiple languages with 6-second latency — expanding the reach of live communication to international audiences.
03
Broadcast-Standard Closed Caption
Generation of A/53 CEA-608/708 Closed Caption directly in live streams, processed by the Josie, Beth, or Carol generators. Full compliance with NBR 15.290/2005.
Performance in numbers
Ultra-low.
Ultra-reliable.
Designed for the pace of live transmission — where every second matters and accuracy is not optional.
Speaker identification
Automatically classifies speakers with configurable names, organizing captions to make reading easier in programs with multiple participants.
Advanced CC configuration
2 or 3 Roll-Up lines, position (top, 4/5, or bottom), automatic uppercase, background and text color adjustment — full control over visual presentation.
Automatic absence detection
Automatically identifies content without captions, ensuring no segment is transmitted without accessibility.
Autonomous or integrated operation
Works independently or integrated with the IFN100, creating a complete, scalable solution for operations of any size.
Built-in CC generator
Enables fully independent operation from external sources, with Closed Caption extraction via SDI and re-encapsulation with integrated encoding.
Automated hybrid operation
