Claim:
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; 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; and a multiplexer, coupled to one of the first buffer and the second buffer; 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; entropy decoding of the second tile is started before the first tile is fully entropy decoded; and when entropy decoding of the first tile encounters a tile boundary, the multiplexer switches between the first buffer and the second buffer.
