AUDIO ENCODER AND AUDIO DECODER WITH METADATA INFORMATION ON PROGRAM OR STRUCTURE OF INSERTED STREAMS Russian patent published in 2016 - IPC G10L19/00 G10L19/16 

FIELD: acoustics.

SUBSTANCE: invention relates to means of generating an encoded bit audio stream, which comprises inserting into a bit stream of metadata a structure of embedded streams and/or metadata of information on program and audio data. Technical result consists in improvement of quality of generated audio data. Module for processing audio data includes data processing subsystem, connected with said buffer memory. Buffer memory stores one frame of encoded audio bit stream, and said frame comprises metadata information on program or metadata structures of embedded streams in one segment of metadata of one field of ignored data of said frame and audio data in yet another segment of said frame. Said data processing sub-system is configured to perform following operations: generating a bit stream, decoding a bit stream or adaptive processing of audio bit stream using metadata of bit stream, or following operations: authentication, validation of audio data or metadata bit stream using metadata of bit stream.

EFFECT: said metadata segment comprises one payload of metadata.
