  • Apparatus and method for encoding and decoding spatial parameter
    Patent number: 9071919
    Abstract: An apparatus and method for encoding and decoding a spatial parameter are provided. A spatial parameter encoding apparatus may encode a spatial parameter using a correlation between spatial parameters indicating a characteristic relationship between channels of a multi-channel audio signal, so that the multi-channel audio signal may be efficiently encoded.
    Type: Grant
    Filed: October 12, 2011
    Date of Patent: June 30, 2015
    Assignee: SAMSUNG ELECTRONICS CO., LTD.
    Inventors: Hwan Shim, Eun-Mi Oh, Mi-Young Kim, Anton V. Porov
  • Apparatus and method for encoding and decoding multichannel signal
    Patent number: 8824577
    Abstract: Disclosed is an apparatus for encoding and decoding multi-channel signals. The apparatus for encoding the multi-channel signals may shift a phase of the multi-channel signals based on a characteristic of the multi-channel signals. An encoded bitstream with respect to the multi-channel signals may be generated using a downmix signal and a residual signal extracted from the phase-shifted multi-channel signals.

  • Apparatus and method for lossless coding and decoding
    Patent number: 7973683
    Abstract: A lossless coding and/or decoding apparatus and method. The lossless coding apparatus may read a probability model corresponding to each of a plurality of context groups. Here, the probability model stored in a memory may be generated by grouping a context. The lossless coding apparatus may code a symbol using the probability model and generate a bitstream. The lossless coding apparatus may enhance coding efficiency and reduce an amount of space utilized by the memory.
