Patent Number Title Of Patent Date Issued
8224658 Method, medium, and apparatus encoding and/or decoding an audio signal July 17, 2012
A method, medium, and apparatus encoding and/or decoding an audio signal. The method of encoding an audio signal includes transforming an input audio signal into an audio signal in a frequency domain, quantizing the frequency-domain transformed audio signal, and performing bitplane codin
8219393 Error concealment method and apparatus for audio signal and decoding method and apparatus for au July 10, 2012
An error concealment method and apparatus for an audio signal and a decoding method and apparatus for an audio signal using the error concealment method and apparatus. The error concealment method includes selecting one of an error concealment in a frequency domain and an error conce
8212693 Bit-stream processing/transmitting and/or receiving/processing method, medium, and apparatus July 3, 2012
A method, medium, and apparatus hierarchically coding/decoding audio data, such as bit sliced arithmetic coding (BSAC), such that payloads of audio data and extension data can be grouped and interleaved according to priority so that some groups of the payloads are dropped, and the re
8055500 Method, medium, and apparatus encoding/decoding audio data with extension data November 8, 2011
A method, medium, and apparatus encoding/decoding audio data in which audio data is hierarchically encoded, and at least one extension data of the audio data is encoded using at least one encoding method, and decoding is performed in the same manner, thereby ensuring fine grain scala
7974839 Method, medium, and apparatus encoding scalable wideband audio signal July 5, 2011
Provided is a method and apparatus for encoding a scalable wideband audio signal, the method including: filtering a voiced signal by performing linear prediction on the voiced signal and modulating the filtered signal; encoding the modulated signal in the time domain, and outputting
7864843 Method and apparatus to encode and/or decode signal using bandwidth extension technology January 4, 2011
A method and apparatus to perform bandwidth extension encoding and decoding encodes and/or decodes a high frequency signal using an excitation signal for a low frequency signal encoded in a time domain or a frequency domain or using an excitation spectrum for the low frequency signal
7498959 Apparatus and method of wideband decoding to synthesize a decoded excitation signal with a gener March 3, 2009
Encoding and/or decoding a wideband signal produces high frequency band spectra from low frequency band spectral information. Linear prediction filter coefficients are determined for the entire wideband spectrum of an input signal. An energy value in each of a plurality of sub-bands in t
