APPARATUS AND METHOD FOR BUFFERING CONTEXT ARRAYS REFERENCED FOR PERFORMING ENTROPY DECODING UPON MULTI-TILE ENCODED PICTURE AND RELATED ENTROPY DECODER

摘要

A buffering apparatus for buffering context arrays of a multi-tile encoded picture having a plurality of tiles includes a first buffer and a second buffer. The first buffer is arranged to buffer a first context array referenced for performing entropy decoding upon a first tile of the multi-tile encoded picture. The second buffer is arranged to buffer a second context array referenced for performing entropy decoding upon a second tile of the multi-tile encoded picture. When the first tile is currently decoded according to the first context array buffered in the first buffer, the second context array is buffered in the second buffer.

1. A buffering apparatus for buffering context arrays of a multi-tile encoded picture having a plurality of tiles, the buffering apparatus comprising:
a first buffer, arranged to buffer a first context array referenced for performing entropy decoding upon a first tile of the multi-tile encoded picture; and a second buffer, arranged to buffer a second context array referenced for performing entropy decoding upon a second tile of the multi-tile encoded picture; wherein when the first tile is currently decoded according to the first context array buffered in the first buffer, the second context array is buffered in the second buffer.
