OCR Video Subtitles

Automatically transcode DVB bitmap subtitles to text for OTT delivery to any client, in any screen size and for any language.

TV subtitles are often delivered as images, or bitmaps, which works well for conventional set-top boxes. However, OTT streaming formats like HLS, Smooth streaming and MPEG-DASH do not support bitmap subtitles in a good way.

With Edgeware’s Cavena-based solution you can quickly and easily prepare high quality OCR video subtitles for glitch-free OTT delivery – to any client, in any screen size and for any language, including Asian character sets.

The OCR Subtitling solution from Cavena uses Optical Character Recognition (OCR) technology to automatically – and instantly – transcode DVB bitmap subtitles to text-based subtitle formats (DVB Teletext or Cavena P31). This makes it possible to use any ABR format needed for multiscreen OTT delivery and get high quality MPEG-DASH, MSS and HLS subtitles.

Cavena OCR Subtitles can be deployed in public or private clouds, in data centers or on COTS hardware. The product is also available as part of the Edgeware Cloud Service, integrated with the tools to repackage and deliver the OTT streams in any format.
