Abstract: An encoding/decoding method, an coder/decoder (codec) and a radio communication device utilize a variable offset coding technique. In accordance with the technique, the start of processing of a first frame is time offset in relation to the end of the processing of the frame that precedes the first frame, the time offset bringing about a time gap between the end of the preceding frame and the start of processing the first frame. A substitution signal is inserted in the time gap.

Abstract: The present invention relates to an improved scheme for coding of audio. In particular, the present invention relates to an encoder device and a method for coding an input signal in an encoder system. The method comprises applying a first mode to the input signal to form a first output and applying a second mode to the input signal to form a second output. A first processed output is then formed from at least a part of the first output, and a second processed output is formed from at least a part of the second output. Forming a second processed output comprises estimating a part of the input signal from at least a part of the second output. Then, an optimum mode is determined based on the firstprocessedoutput and the secondprocessedoutput, and the output according to the optimum mode is selected.

Abstract: A method and arrangement for dynamically adapting thresholds used for selecting a codec mode to be used is presented. Thresholds are adapted in response to the current received signal quality. An estimate of actual prevailing received signal quality is obtained on which the adaptation is based. The present invention can be applied either on the mobile terminal side or on the network side, working on the uplink and/or the downlink. The thresholds can be modified on the receiving side, or, when operating in the network and working on the downlink, the threshold adaptation can be initiated in the terminal.

Abstract: According to the invention a receiving end terminal (RET) enters a delay mode based on the detecting of the quality of the link being lower than a threshold. In this delay mode, the receiving end terminal provides a reception delay indicator (RDI) for a sending end terminal (SET). The sending end terminal (SET) receives the reception delay indicator (RDI) and provides an end of speech indicator (ESI) for the receiving end terminal (RET) at an end of a speech coding interval (SC). The receiving end terminal (RET) uses the reception delay indicator (RDI) and end of speech indicator (ESI) to define a first time interval (AL1) during which a speech decoder is disabled. The speech decoder is again activated after the first time interval (AL1).

Abstract: A parametric model is used for error concealment. The model filter allows for recovering signal components of original audio channel signals that now are lost or erroneous from signal components of at least one other audio channel. During error-free reception of valid frames, the parameters of that model will be derived and stored. In case of frame loss or frame error affecting the multi-channel information, a conjecture of the missing information is recovered by applying the model, using the stored parameters. In case of several subsequent lost or erroneous frames, it is possible either to use the parameters derived during the last valid frame or to use parameters derived from the recovered multi-channel information of the respective previous invalid frame. Furthermore, if there are long sequences of lost frames, it can be beneficial to apply some gradual muting of the model parameters, which essentially results in a gradual attenuation of the recovered multi-channel information.
