High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936;[1] in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV.
