Overcoming Web And Mobile Subtitle Challenges
By Gordon Hunter, Chief Sales Officer, Softel
There are both public service and commercial benefits in making content available to as wide an audience as possible. Users frequently ‘watch’ rather than ‘listen’ to streamed content. The provision of language subtitles is also more advantageous to new media operators than for conventional broadcasters as online content might be accessed by viewers globally. In the evolving desktop and mobile video landscape, in many cases, subtitle streams have to be created to match the individual needs of the target viewer platform. The challenge comes in knowing how and what subtitle file format is needed for each new media platform – the format and file types vary widely. In the USA, there is a legal mandate for content owners and broadcasters to make available caption files in the new SMPTE 2052 IP caption file format. Many web and mobile streamer platforms require a caption file which is close in specification to a DFXP ‘timed text’ file, and in Europe the EBU are promoting the EBU-TT subtitle file format. The challenge to media operators is to decide where and when in the subtitle production and management workflow to produce these web and mobile derivative subtitle files. Softel offers a professional subtitle workstation – Swift Create – that is capable of exporting subtitle files in many different formats. This is the easiest way for subtitle service companies to deliver multiformat subtitle files to their media distribution customers. Content distribution facilities then have the challenge of transcoding the master video into the wide range of compressed video streaming file formats required for the various platforms. In this case it makes sense to produce the IP File formats for multiplatform development subtitle files as part of the video

transcoding process. Transcoder suppliers frequently license subtitle plug-ins from subtitle specialists, such as Softel’s Swift vTX filebased subtitle processor. It offers the means to extract subtitles from the source video and create IP format subtitle files, or they can offer transcoding from one subtitle file format to another. Many MAM suppliers offer Softel’s Swift vTX OEM subtitle plug-ins to facilitate subtitle browsing, QC and multi-format subtitle file export. Additionally, a standalone Swift vTX subtitle file format transcoder offers the ultimate flexibility to be deployed as an independent tool in the media publishing process. S o f t e l ’s c o m p r e h e n s i v e guide examining subtitling and closed captioning challenges is available online. ■ 61
