摘要 |
<p>A method of and an apparatus for encoding and decoding image information such as a sub-picture which is reproduced or played back simultaneously with a main picture. A sub-picture packet is encoded using a packet header containing a time stamp, sub-picture data containing compressed pixel data, one or more display control sequences, and a sub-picture unit header. The time stamp indicates the playback start time of the sub-picture packet. The display control sequence defines the order of display of the sub-picture data. The sub-picture unit header indicates the size of the sub-picture packet and the location of the display control sequence. The encoded sub-picture packet is decoded, and displayed based on the display control sequence.</p> |
