Abstract

The present invention relates to a caption-generating method of lyric caption data and to a caption display method. The caption-generating method according to the present invention comprises the steps of: (a) splitting audio data into multiple reference sections; (b) extracting a reference sound from sounds in the audio data in each of the reference sections; (c) setting a reference location corresponding to the reference sound in a caption-displaying region in which a lyrics caption is to be displayed vertically within an overall screen; and (d) generating lyric caption data such that a lyric caption corresponding to the reference sound is displayed on the reference location of the caption-displaying region in one reference section, and the remaining lyric-captions are displayed in a location in which verticality is determined according to a pitch difference from the reference sound in the one reference section. Accordingly, when the lyric caption displayed in synchronization with audio data visually represents the pitch of the audio data, pitch can be clearly visually distinguished.
