This chapter gives an overview of subtitling for the deaf and hard of hearing (SDH). Starting with terminological issues related to terminology and the question of SDH being intra- or interlingual, the SDH target group is presented and their needs and preferences related to subtitles are discussed. Then, the chapter focuses on various SDH characteristics, such as speaker identification and description of sounds and music. Different broadcast methods are outlined and compared: live, semi-live and prerecorded subtitles. A brief historical overview of SDH is presented, together with relevant legislation which prompted SDH development in many countries. Last but not least, current and future research themes in SDH are discussed.
