Abstract

Subtitle searching is achieved by encoding a subtitle to be displayed exclusively during a trick playback mode.
Addresses for the subtitle to be played back during the trick playback mode are stored on a record medium reserved for addresses. A computer-readable memory directs a computer to retrieve these addresses and locate subtitles to be displayed during the trick playback mode on the record medium. The subtitles are searched by decoding and displaying the subtitles located at the addresses on the record medium to be displayed during the trick playback mode.
