Patent application number | Description | Published |
20100145688 | Method and apparatus for encoding/decoding speech signal using coding mode - An apparatus and a method to encode and decode a speech signal using an encoding mode are provided. An encoding apparatus may select an encoding mode of a frame included in an input speech signal, and encode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode. | 06-10-2010 |
20100324912 | Context-based arithmetic encoding apparatus and method and context-based arithmetic decoding apparatus and method - Disclosed are a context-based arithmetic encoding apparatus and method and a context-based arithmetic decoding apparatus and method. The context-based arithmetic decoding apparatus may determine a context of a current N-tuple to be decoded, determine a Most Significant Bit (MSB) context corresponding to an MSB symbol of the current N-tuple, and determine a probability model using the context of the N-tuple and the MSB context. Subsequently, the context-based arithmetic decoding apparatus may perform a decoding on an MSB based on the determined probability model, and perform a decoding on a Least Significant Bit (LSB) based on a bit depth of the LSB derived from a process of decoding on an escape code. | 12-23-2010 |
20110103592 | Apparatus and method encoding/decoding with phase information and residual information - Provided is an apparatus and method of encoding and decoding multiple channel signals based upon phase information and one or more residual signals. | 05-05-2011 |
20120020482 | APPARATUS AND METHOD FOR ENCODING AND DECODING MULTI-CHANNEL AUDIO SIGNAL - Disclosed is an apparatus for encoding and decoding a multi-channel audio signal. The apparatus for encoding the multi-channel audio signal groups channels of a multi-channel audio signal, eliminates redundant information between channels using a mixing matrix including phase information, converts a frequency of the signal, and encodes the signal. | 01-26-2012 |
20120221325 | CONTEXT-BASED ARITHMETIC ENCODING APPARATUS AND METHOD AND CONTEXT-BASED ARITHMETIC DECODING APPARATUS AND METHOD - Disclosed are a context-based arithmetic encoding apparatus and method and a context-based arithmetic decoding apparatus and method. The context-based arithmetic decoding apparatus may determine a context of a current N-tuple to be decoded, determine a Most Significant Bit (MSB) context corresponding to an MSB symbol of the current N-tuple, and determine a probability model using the context of the N-tuple and the MSB context. Subsequently, the context-based arithmetic decoding apparatus may perform a decoding on an MSB based on the determined probability model, and perform a decoding on a Least Significant Bit (LSB) based on a bit depth of the LSB derived from a process of decoding on an escape code. | 08-30-2012 |
20140074461 | METHOD AND APPARATUS FOR ENCODING/DECODING SPEECH SIGNAL USING CODING MODE - An apparatus and a method to encode and decode a speech signal using an encoding mode are provided. An encoding apparatus may select an encoding mode of a frame included in an input speech signal, and encode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode. | 03-13-2014 |
20150124974 | APPARATUS AND METHOD ENCODING/DECODING WITH PHASE INFORMATION AND RESIDUAL INFORMATION - Provided is an apparatus and method of encoding and decoding multiple channel signals based upon phase information and one or more residual signals. | 05-07-2015 |
20150348560 | APPARATUS FOR ENCODING/DECODING MULTICHANNEL SIGNAL AND METHOD THEREOF - Provided is an encoding/decoding apparatus and method of multi-channel signals. The encoding apparatus and method of multi-channel signals may encode phase information of the multi-channel signals using a quantization scheme and a lossless encoding scheme, and the decoding apparatus and method of multi-channel signals may decode the phase information using an inverse-quantization scheme and a lossless decoding scheme. | 12-03-2015 |
