Abstract:
1. A subpicture decode and execution system, comprising: a first processor arranged to parse a received video data stream into a number of separate packs some of which are subpicture video packs; and a second processor coupled to the first processor arranged to receive the subpicture video packs from the first processor, wherein the second processor processes a received subpicture video pack to provide a subpicture pixel data (PXD), a subpicture control command data (SP DCSQT), a pixel data pointer (PTR) that points to an associated subpicture pixel data (PXD) and a corresponding pointer time stamp (PTS) that indicates a time that a particular subpixel data (PXD) pointed to by a corresponding pointer PTR will be needed for further processing and video object unit (VOBU) information.
