Abstract: A system and method for providing improved adaptive multi-rate wideband (AMR-WB) discontinuous transmission (DTX) synchronization. According to various embodiments, an indication on the start of the inactive speech period is signalled to the decoder via a voice activity detection (VAD) flag a predetermined number of frames before the DTX period will start, i.e., before the SID_FIRST frame is received. When the VAD flag indicates active speech, or when the VAD flag has been set to zero less than the predetermined number of frames ago, the received NO_DATA frame can be classified with a high degree of reliability as active speech, i.e., considered as transmitter, network or terminal-initiated signalling, and can be substituted by a SPEECH_LOST frame. When the VAD flag was set to zero eight frames ago or earlier, the NO_DATA frame is classified as DTX.

Abstract: An apparatus may include a contextual characteristic determiner configured to determine a contextual characteristic of a location. A sensory device may collect sensed data and location information which is used to determine the contextual characteristic of the location. The sensed data, contextual characteristic and/or location information may be compiled into a database by a database compiler. Further, an ambient content package sharer may request and/or provide sensed data and/or determined contextual characteristics to other devices or the database compiler for inclusion in the database. An augmentative content adaptor may thereby provide for adaptation of an augmentative content for output at the location based on the contextual characteristic. Contextual characteristics may include audible contextual characteristics and visual contextual characteristics.

Abstract: A method for supporting an encoding of an audio signal is shown, wherein at least a first and a second coder mode are available for encoding a section of the audio signal. The first coder mode enables a coding based on two different coding models. A selection of a coding model is enabled by a selection rule which is based on signal characteristics which have been determined for a certain analysis window. In order to avoid a misclassification of a section after a switch to the first coder mode, it is proposed that the selection rule is activated only when sufficient sections for the analysis window have been received. The invention relates equally to a module in which this method is implemented, to a device and a system comprising such a module and to a software program product including a software code for realizing the proposed method.
