  • Method and apparatus for generating bitstream of audio signal and audio encoding/decoding method and apparatus thereof
    Patent number: 7869891
    Abstract: A method and apparatus for generating a bitstream of an audio signal, in which an audio signal can be easily extended to a multichannel audio signal, the processing speed of an audio signal can be improved, and channel signals of an audio signal can be processed simultaneously, and an audio encoding/decoding method and apparatus using the method and apparatus. The method for generating a bitstream of an audio signal using an encoded audio signal and encoding information includes generating a flag indicating whether the encoded audio signal is a multichannel audio signal, generating a bitstream header including the generated flag, and generating the bitstream using the generated bitstream header and the encoded audio signal.
