Japanese captioning FAQs

Can SyncWords generate Japanese captions for live broadcasts?

Yes. SyncWords generates real-time Japanese captions for live broadcasts and streams, delivered as DVB subtitles for broadcast television or as WebVTT for HLS streaming. No hardware encoder required.

Can Japanese captions run on broadcast television?

Yes. Japanese cannot be carried natively in EIA-608, so broadcast chains use DVB subtitles instead: DVB-SUB carries any script because it is rasterised, and DVB-TTML carries Japanese text. Web delivery uses WebVTT.

Can you translate English content into Japanese subtitles in real time?

Yes. Live AI Translation produces Japanese subtitles from English audio in real time, with 163 subtitle languages available for other audiences.

What Japanese caption file formats can I export?

SRT, WebVTT, TTML/DFXP and more for web and file workflows, plus DVB-SUB and DVB-TTML for broadcast delivery.
