DECODING DEVICE, DECODING METHOD, ENCODING DEVICE, ENCODING METHOD, AND PROGRAM

摘要

The present art relates to a decoding device and method, an encoding device and method, and a program, with which more immersive, high quality sound can be achieved. The encoding device stores information that indicates the presence or absence of extended information in a bitstream. During decoding of the encoded bitstream, extended information is retrieved depending on the retrieved information indicating the presence or absence of extended information, and on the basis of said retrieved extended information, processing is implemented on audio data.
