The Technical Module's group on Subtitling is one of the older ad-hoc groups, dating back to 1994. DVB Subtitling is an integral part of the DVB set of specifications, and its bitmapped mechanisms are a powerful value-added tool for operators.
Under its current chairman, the subtitling group is responsible for the following standard:
EN 300 743 Digital Video Broadcasting (DVB); DVB Subtitling
The DVB-Subtitling Group was re-activated in January 2014, to investigate subtitles for current and future services (including UHDTV).
