摘要： In a multi-channel encoder generating several different parameter sets for reconstructing a multi-channel output signal using at least one transmission channel, the data stream is written such that the two parameter sets are decodable independently of each other. Thus, a multi-channel decoder is enabled to skip a parameter set which is marked as optional and/or has a higher version number when reading the data stream and still to perform a valid multi-channel reconstruction using a data set marked as mandatory or a data set having a sufficiently low version number. This achieves a flexible encoder/decoder concept suitable for future updates characterized by backward compatibility and reliability.

摘要： Parameters being a measure for a characteristic of a channel or of a pair of channels, wherein the parameter is a measure for a characteristic of the channel or of the pair of channels with respect to another channel of a multi-channel signal can be quantized more efficiently using a quantization rule that is generated based on a relation of an energy measure of the channel or the pair of channels and an energy measure of the multi-channel signal. With generation of the quantization rule taking into account a psycho acoustic approach, the size of an encoded representation of the multi-channel signal can be decreased by coarser quantization without significantly disturbing the perceptual quality of the multi-channel signal when reconstructed from the encoded representation.

摘要： A process for transmitting and/or storing digital signals of multiple chals. This process is suited, in particular, for transmitting the five channels of 3/2 stereophony as well as for transmitting two stereo channels and three additional commentary channels. In this manner, by way of illustration, television programs with multi-language audio signals can be transmitted. This process is distinguished in that by reduction of the to-be-transmitted data, only a bit rate of 384 kbit/s is required for transmission. The reduction of the data is achieved by the K input channels being imaged in segments onto the N.ltoreq.K virtual spectral data channels, by the spectral data channels being quantized, coded, and transmitted taking into consideration the principles of psychoacoustics, and by K output channels being reproduced from the transmitted bit stream with the aid of a transmitted list from the N.ltoreq.K spectral data channels.

摘要： A process for reducing data in the transmission and/or storage of digital signals of several interdependent channels is described. As the signals from the channels are not independent of one another, an additional data quantity reduction is possible during transmission. In known processes for the coding of signals from two stereo channels, in the case of an unfavorable signal composition interference can be caused by the coding process and cannot be concealed by the signal actually present in the channel and consequently reduce listening enjoyment. In the process according to the invention and with the aid of the spectral values of corresponding blocks of several channels, there is a balancing of the necessary data rate for a separate coding of the two channels and for a joint coding. There is a joint coding of the channels for as long as the data rate for the joint coding does not exceed by a predeterminable value the data rate for the separate coding of the particular channel. In this case the spectral values of the corresponding blocks are similar, so that a joint coding is preferred. In the case of highly dissimilar signals the balancing leads to a separate transmission of the signals. In order to ensure that there is no interference, temporarily no use is made of the joint coding of several channels.
摘要翻译：描述了用于减少数个相互依赖的信道的数字信号的发送和/或存储中的数据的过程。由于来自信道的信号不是彼此独立的，所以在传输期间可以进一步减少数据量。在用于编码来自两个立体声信道的信号的已知过程中，在不利的信号组合的情况下，可能由编码过程引起干扰，并且不能被实际存在于信道中的信号所隐藏，从而减少听觉享受。在根据本发明的过程中并且借助于几个信道的相应块的频谱值，存在对于两个信道的单独编码和联合编码的必要数据速率的平衡。只要联合编码的数据速率不超过特定信道的单独编码的数据速率的可预定值，则存在信道的联合编码。在这种情况下，相应块的频谱值是相似的，因此优选联合编码。在高度不相似信号的情况下，平衡导致信号的单独传输。为了确保没有干扰，暂时没有使用几个通道的联合编码。

摘要： In order to analyze an information signal, a significant short-time spectrum is extracted from the information signal, the means for extracting being configured to extract such short-time spectra which come closer to a specific characteristic than other short-time spectra of the information signal. The short-time spectra extracted are then decomposed into component signals using ICA analysis, a component signal spectrum representing a profile spectrum of a tone source which generates a tone corresponding to the characteristic sought for. From a sequence of short-time spectra of the information signal and from the profile spectra determined, an amplitude envelope is eventually calculated for each profile spectrum, the amplitude envelope indicating how a profile spectrum of a tone source all in all changes over time. The profile spectra and all the amplitude envelopes associated therewith provide a description of the information signal which may be evaluated further, for example for transcription purposes in the case of a music signal.

摘要： The envelope of a decorrelated signal derived from an original signal can be shaped without introducing additional distortion, when a spectral flattener is used to spectrally flatten the spectrum of the decorrelated signal and the original signal prior to using the flattened spectra for deriving a gain factor describing the energy distribution between the flattened spectra, and when the so derived gain factor is used by an envelope shaper to timely shape the envelope of the decorrelated signal.

摘要： The apparatus for constructing a multi-channel output signal using an input signal and parametric side information, the input signal including the first input channel and the second input channel derived from an original multi-channel signal, and the parametric side information describing interrelations between channels of the multi-channel original signal uses base channels for synthesizing first and second output channels on one side of an assumed listener position, which are different from each other. The base channels are different from each other because of a coherence measure. Coherence between the base channels (for example the left and the left surround reconstructed channel) is reduced by calculating a base channel for one of those channels by a combination of the input channels, the combination being determined by the coherence measure. Thus, a high subjective quality of the reconstruction can be obtained because of an approximated original front/back coherence.

摘要： A compact encoded representation of information values not exceeding a predefined size can be derived when a first encoding rule generating an encoded representation of the information values of variable length is compared to a second encoding rule generating an encoded representation of the information values of fixed length and when the encoding rule resulting in the encoded representation requiring the lower number of information units is chosen. Thus, the maximum bit rate can be guaranteed to be at least the maximum bit rate of the second encoding rule deriving the second encoded representation. Signaling the choice of the encoding rule by some rule information together with the encoded representation of the information values, the correct information values can later on be derived on a decoder side, using a decoding rule fitting the encoding rule used during the encoding.
