Abstract
A method for read pointer maintenance of a buffering apparatus, which is arranged to buffer data of a multi-tile encoded picture having a plurality of tiles included therein, includes the following steps: judging if decoding of a first tile of the multi-tile encoded picture encounters a tile boundary of the first tile; and when it is judged that the tile boundary of the first tile is encountered, storing a currently used read pointer into a pointer buffer, and loading a selected read pointer from the pointer buffer to act as the currently used read pointer.
Claims19
A method for read pointer maintenance of a buffering apparatus which is arranged to buffer data of a multi-tile encoded picture having a plurality of tiles included therein, the method comprising:
- judging if decoding of a first tile of the multi-tile encoded picture encounters a tile boundary of the first tile;
- and
- when it is judged that the tile boundary of the first tile is encountered, storing a currently used read pointer into a pointer buffer, and loading a selected read pointer from the pointer buffer to act as the currently used read pointer.
A buffer controller for read pointer maintenance of a buffering apparatus which is arranged to buffer data of at least a multi-tile encoded picture having a plurality of tiles included therein, the buffer controller comprising:
- a judging unit, arranged for judging if decoding of a first tile of the multi-tile encoded picture encounters a tile boundary of the first tile;
- and
- a control unit, arranged for storing a currently used read pointer into a pointer buffer and loading a selected read pointer from the pointer buffer to act as the currently used read pointer when the judging unit judges that the tile boundary is encountered.
A buffering apparatus for buffering data of at least a multi-tile encoded picture having a plurality of tiles included therein, the buffering apparatus comprising:
- a first storage space, arranged to buffer a first tile of the multi-tile encoded picture;
- and
- a second storage space, arranged to buffer a second tile of the multi-tile encoded picture;
- wherein the first tile is currently decoded, and the second tile is not currently decoded.
