Method and apparatus for encoding and decoding image information |
摘要 |
<p>A sub-picture packet is encoded using a packet header (PH) containing a time stamp, sub-picture data (32) containing compressed pixel data (PXD), one or more display control sequences (33), and a sub-picture unit header (31). The time stamp indicates the playback start time of the sub-picture packet. The display control sequence (DCSQT) defines the order of display of the sub-picture data (PXD). The sub-picture unit header (SPUH) indicates the size of the sub-picture packet and the location of the display control sequence (DCSQT). The encoded sub-picture packet is decoded, and displayed based on the display control sequence (DCSQT). <IMAGE></p> |
