DE-CODING DEVICE, DECODING METHOD, CODING DEVICE, CODING METHOD AND PROGRAM Russian patent published in 2018 - IPC G10L19/08 G10L19/20 H04S5/02 

FIELD: information technology.

SUBSTANCE: invention relates to devices for information decoding and encoding. Coding device stores information about the location of the loudspeakers in the comment area in the EFS of the coded bitstream and stores the synchronous word and identification information in the comment area, so that other public comments and speaker location information stored in the comment area may be different from each other. When the encoded bitstream is decoded, whether the speaker location information is stored, is determined based on the synchronous word and identification information stored in the comment area. Audio data contained in the coded bit stream is output according to the location of the loudspeakers in accordance with the determination result.

EFFECT: technical result is to increase the coding efficiency to produce high-quality realistic sound.
