This paper proposes a method to enable visually impaired viewers to access data broadcasting content by using various accessible devices. Data broadcasting, coded in Broadcast Markup Language, has been almost inaccessible because of its usage of dynamic HTML features and lack of semantics. This method uses a template rule to transcode BML content into an accessible static description with structure and semantics. An implementation of a trial receiver system and an experiment on transcoding are described.
