Abstract:
1. A method of decoding an audio signal, comprising: receiving an audio data frame having at least one channel, the channel being subdivided into a plurality of blocks, at least two of the blocks being capable of different lengths; obtaining indicator information indicating whether determining of a first prediction order for each block is allowed; obtaining a second prediction order if the indicator information indicates that determining of the first prediction order for each block is not allowed, the second prediction order being applied to all of the plurality of blocks; determining the first prediction order for each block from the audio signal if the indicator information indicates that determining of the first prediction order for each block is allowed, the first prediction order for each block having been determined according to the second prediction order and a length of the block; and decoding each block using the determined first prediction order for each block or the obtained second prediction order for the plurality of blocks.
