The EBU has launched several activities to help product implementers and users work with EBU-TT.

First of all there now is a github repository that provides public access to an informative (editors draft) XML Schema for EBU-TT-D, parts of which were developed in the European collaborative research project HBB4ALL. The Schema is intended to support the implementation of EBU-TT-D (Tech 3380) and is released under the BSD-3 open source license.

Experimental dash.js implementation

Another github repository provides an experimental implementation of EBU-TT-D subtitles for dash.js, a reference client implementation for the playback of MPEG DASH via JavaScript and compliant browsers. This is ongoing work that not only helps DASH implementers get acquinted with EBU-TT-D, but also others who would like to render EBU-TT-D subtitles over online content.
