Abstract:
The present disclosure relates to a decoding apparatus, a decoding method, and a program that can switch, as quickly as possible, a plurality of audio encoded bit streams with synchronized reproduction timing to thereby decode and output the plurality of audio encoded bit streams. An aspect of the present disclosure provides a decoding apparatus including: an acquisition unit that acquires a plurality of audio encoded bit streams; a selection unit that determines a boundary position for switching output of the plurality of audio encoded bit streams and that selectively supplies one of the plurality of acquired audio encoded bit streams to a decoding processing unit according to the boundary position; and the decoding processing unit that applies a decoding process including IMDCT processing to the one input through the selection unit, in which the decoding processing unit skips overlap-and-add in the IMDCT processing corresponding to each frame before and after the boundary position. The present disclosure can be applied to, for example, a reception apparatus, a reproduction apparatus, and the like.

Claim (Index 1):
A decoding apparatus comprising:\n an acquisition unit that acquires a plurality of audio encoded bit streams in which a plurality of pieces of source data with synchronized reproduction timing are each encoded on the basis of frames after MDCT processing; a selection unit that determines a boundary position for switching output of the plurality of audio encoded bit streams and that selectively supplies one of the plurality of acquired audio encoded bit streams to a decoding processing unit according to the boundary position; and the decoding processing unit that applies a decoding process including IMDCT processing corresponding to the MDCT processing to one of the plurality of audio encoded bit streams input through the selection unit, wherein the decoding processing unit skips overlap-and-add in the IMDCT processing corresponding to each frame before and after the boundary position.
