ABSTRACT:
This invention relates to a method of conducting search of moving picture data stream and repeating playback of a data stream section based on the caption information, which is displayed with moving pictures, and a reproduction apparatus using such method. The present method creates and stores link information between caption data and position of moving picture stream which is reproduced concurrently with the caption data; displays a part of the caption data during playback; searches for a moving picture data section, which is concurrently presented with a particular caption chosen from the displayed caption data by a viewer, based on the created link information; and repeats playback of the found moving picture data section. This method is very useful to language practice because it can repeat to play a video section containing captions that a viewer wants to listen repeatedly.
