Patent number: 9858934Abstract: Provided is an audio encoding method. The audio encoding method includes: acquiring envelopes based on a predetermined sub-band for an audio spectrum; quantizing the envelopes based on the predetermined sub-band; and obtaining a difference value between quantized envelopes for adjacent sub-bands and lossless encoding a difference value of a current sub-band by using a difference value of a previous sub-band as a context. Accordingly, the number of bits required to encode envelope information of an audio spectrum may be reduced in a limited bit range, thereby increasing the number of bits required to encode an actual spectral component.Type: GrantFiled: March 6, 2017Date of Patent: January 2, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Anton Porov, Konstantin Osipov, Ki-hyun Choo

Patent number: RE47824Abstract: Provided is a method and apparatus for encoding or decoding a signal corresponding to a high frequency band in an audio signal. The method and apparatus for encoding a high frequency band detects and encodes frequency component(s) according to a pre-set criterion from a signal corresponding to a frequency band higher than a pre-set frequency and encodes energy value(s) of a signal to reconstruct band(s) in which the detected frequency component(s) are included. The method and apparatus for decoding a high frequency band decodes the signal by adjusting a signal to reconstruct a band in which important frequency component(s) are included by considering an energy value of the important frequency component(s). Accordingly, even though encoding or decoding is performed using a small number of bits, there is no degradation in sound quality of a signal corresponding to a high frequency band, and thus coding efficiency can be maximized.Type: GrantFiled: October 14, 2015Date of Patent: January 21, 2020Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ki-hyun Choo, Anton Porov, Eun-mi Oh, Jung-hoo Kim
