<p>Encoding and decoding of subtitle data is performed in real time. A buffer regulates a flow rate of the subtitle data to ensure that appropriate subtitles are superimposed on the correct video picture. In encoding, subtitles are generated in correspondence with a video picture. The subtitles are separately encoded and multiplexed with the video picture for transmission. Upon decoding, the subtitles are selected at a time which corresponds to display of the corresponding video picture. Since the subtitles are processed separately from the video data, the subtitles may be manipulated with great control, thus providing more flexibility in encoding and decoding. <IMAGE></p> |
