Abstract: A font changing method for the subtitles of a video is provided. The method utilizes a playback program, which is implemented as a software application or a program embedded in a playback device, to provide a font selection function for the subtitles of the video. Therefore, a user can configure the subtitles easily. This method is used for a DVD that allows separating video streaming and subtitle data. After the playback program has received an activation signal, several steps for changing the font before playing the video are included. Firstly, the playback program receives a subtitle settings signal, and then receives a font selection signal in the settings item. Next, the program accesses a font database built in a storage medium. After that, the program links up to a selected font data. Consequently, the program can play the video after incorporating the font data into the video stream.
