DECODING DEVICE, DECODING METHOD, ENCODING DEVICE, ENCODING METHOD, AND PROGRAM
First Claim
1. A decoding device comprising:
- a decoding unit that decodes audio data included in an encoded bit stream;
a reading unit that reads sound source position information about a height of a sound source of the audio data from a region which can store arbitrary data of the encoded bit stream; and
an output unit that outputs the decoded audio data on the basis of the sound source position information.

Abstract
The present technique relates to a decoding device, a decoding method, an encoding device, an encoding method, and a program which can obtain a high-quality realistic sound.
The encoding device stores speaker arrangement information in a comment region in a PCE of an encoded bit stream and stores a synchronous word and identification information in the comment region such that other public comments and the speaker arrangement information stored in the comment region can be distinguished from each other. When an encoded bit stream is decoded, it is determined whether the speaker arrangement information is stored on the basis of the synchronous word and the identification information stored in the comment region. Audio data included in the encoded bit stream is output according to the arrangement of the speakers corresponding to the determination result. The present technique can be applied to an encoding device.
