<p>Dynamic positioning of subtitles for a video image is achieved by encoding and decoding the subtitles separately from the video image. At the encoder (Fig. 7), subtitles are generated (55) for each respective video image. At the decoder (Fig. 2), a buffer (22) stores the subtitles along with subtitle decoding information. A controller (35) precisely times a reading operation of the buffer to read out the subtitles during a real time display of the respective video image. Dynamic positioning of the subtitles is achieved by delaying the time the controller executes the read operation. When the decoding technique is repeated for a number of frames, the viewer senses motion as the positioning gradually changes. <IMAGE></p> |
