摘要： An automated translation input system to convert Mechanized Translation System (MTS) orders into Recent Change Messages that can be loaded into a program controlled switch without enhancement or changes in the MTS program to provide a significant saving in Switching Control Center (SCC) labor hours. The new system and method permit using the output of the MTS which would otherwise constitute a printed form for inputting the Automated Translation Input System (ATIS) where the forms are analyzed, the associated Recent Changes are analyzed, and the Recent Change Messages are prepared. The thus prepared Recent Change Messages are inspected by the SCC technician who, through a manual option in the ATIS system, gives the command to download the translations directly into the switch. This eliminates the need for key preparation of the Recent Change forms by the SCC technicians and results in an elimination of keying errors and a significant saving in time. At the same time the MTS may provide its conventional printed forms to permit parallel handling of those change messages not selected for handling by ATIS.

摘要： Ambience signal components are obtained from source audio signals, matrix-decoded signal components are obtained from the source audio signals, and the ambience signal components are controllably combined with the matrix-decoded signal components. Obtaining ambience signal components may include applying at least one decorrelation filter sequence. The same decorrelation filter sequence may be applied to each of the input audio signals or, alternatively, a different decorrelation filter sequence may be applied to each of the input audio signals.

摘要： M audio input channels, each associated with a spatial direction, are translated to N audio output channels, each associated with a spatial direction, wherein M and N are positive whole integers, M is three or more, and N is three or more, by deriving the N audio output channels from the M audio input channels, wherein one or more of the M audio input channels is associated with a spatial direction other than a spatial direction with which any of the N audio output channels is associated, and at least one of the one or more of the M audio input channels is mapped to a respective set of at least three of the N output channels. At least three output channels of a set may be associated with contiguous spatial directions.

摘要： In a system in which a low-bit rate encoder and decoder carries matrixed audio signals, an adaptive rematrix rematrixes matrixed signals from an unmodified 4:2 matrix encoder to separate and isolate quiet components from loud ones, thereby avoiding the corruption of quiet signals with the low-bit-rate coding quantization noise of loud signals. The decoder is similarly equipped with a rematrix, which tracks the encoder rematrix and restores the signals to the form required by the unmodified 2:4 matrix decoder. The encoder adaptive rematrix selects the matrix output signals or the amplitude weighted sum and difference of the matrix output signals. The choice of whether the matrix output signals or the sum and difference of the matrix output signals are selected is based on a determination of which results in fewer undesirable artifacts when the output audio signals are recovered in the decoder. The adaptive rematrix may operate on frequency component representations of signals rather than the time-domain signals themselves.
摘要翻译：在低比特率编码器和解码器承载矩阵音频信号的系统中，自适应雷达阵列将来自未修改的4：2矩阵编码器的矩阵化信号重新分组，以将安静分量与大噪声分离并隔离，从而避免了安静信号的损坏大声信号的低比特率编码量化噪声。解码器类似地配备有再生矩阵，其追踪编码器rematrix并将信号恢复到未修改的2：4矩阵解码器所需的形式。编码器自适应rematrix选择矩阵输出信号或矩阵输出信号的振幅加权和和差。选择矩阵输出信号或矩阵输出信号的和和差是否选择是基于当在解码器中恢复输出音频信号时导致更少的不期望的伪影的确定。自适应雷达可以在信号的频率分量表示上操作，而不是时域信号本身。

摘要： The decoder of this invention decodes at least two channel signals in a directional information system where at least four input signals containing directional information have been encoded into the two or more channel signals. The decoder generates a first control signal substantially proportional to the logarithm of the ratio of the amplitudes of two of the channel signals to detect, as between two of the channel signals, whether the amplitude of one signal dominates that of the other. The decoder also generates a second control signal substantially proportional to the logarithm of the ratio of the amplitudes of the sum and the difference between two of the channel signals to detect the dominant signal in terms of amplitude. The decoder includes a matrix means responsive to the two or more channel signals and the two control signals for generating a number of output signals according to an algorithm. The control signals generated are used to steer the directional information systems in such manner through the matrix means that the directional effects of the output signals are enhanced. Two decoders of the type described above may be used to decode the high frequency and low frequency portions of the channel signals where the high and low frequency portions are separated by means of two crossover filters. The crossover frequency of the two crossover filters is controlled so that it is approximately at the top end of the signal frequencies intended for the center loudspeaker. Very low frequency signal components are separately processed and evenly distributed among the left, center and right channels.
