Abstract:
1. A decoding apparatus for decoding encoded first frame data and decoding encoded second frame data on the basis of difference information indicating a difference between reference first frame data using a first parameter and unsmoothed second frame data, the decoding apparatus comprising: a decoding unit configured to decode the encoded first frame data; a first smoothing unit configured to, when the decoding apparatus sets a second parameter, perform smoothing using the second parameter on the first frame data decoded by the decoding unit and output a smoothed first frame data as reproduction first frame data to be reproduced; and a second smoothing unit configured to perform smoothing using the first parameter on the first frame data decoded by the decoding unit and output the smoothed first frame data as reference first frame data for use in reference in decoding the encoded second frame data, wherein the decoding unit is configured to refer to the reference first frame data, which is obtained by smoothing using the first parameter performed by the second smoothing unit, and decode the encoded second frame data on the basis of the difference information indicating the difference between the first frame data subjected to smoothing using the first parameter and the unsmoothed second frame data.
