STORAGE MEDIUM INCLUDING TEXT-BASED CAPTION INFORMATION, REPRODUCING APPARATUS AND REPRODUCING METHOD THEREOF

摘要

A method to reproduce information from a storage medium comprising moving picture data and subtitle data to be output as a graphic overlapping on an image based on the moving picture data. The subtitle data including text data and control information is read from the storage medium. The text data is decoded and caption contents as well as output style information contained therein are parsed. The caption contents are converted into pixel data formed as a bitmap image based on the parsed output style information. The control information comprises time information indicating a time at which the pixel data is generated in a buffer memory and a time at which the pixel data is deleted in the buffer memory. The control information comprises furthermore position information indicating a position at which the pixel data is output. The control information is decoded and the time information as well as the position information are parsed. Finally, the pixel data is output in real time according to the parsed time information and the parsed position information.
