摘要： An apparatus (500) for mixing a plurality of input data streams (510) is described, wherein the input data streams (510) each comprise a frame (540) of audio data in the spectral domain, a frame (540) of an input data stream (510) comprising spectral information for a plurality of spectral components. The apparatus comprises a processing unit (520) adapted to compare the frames (540) of the plurality of input data streams (510). The processing unit (520) is further adapted to determine, based on the comparison, for a spectral component of an output frame (550) of an output data stream (530), exactly one input data stream (510) of the plurality of input data streams (510). The processing unit (520) is further adapted to generate the output data stream (530) by copying at least a part of an information of a corresponding spectral component of the frame of the determined data stream (510) to describe the spectral component of the output frame (550) of the output data stream (530). Further or alternatively, the control value of the frames (540) of the first input data stream (510-1) and the second input data stream (510-2) may be compared to yield a comparison result and, if the comparison result is positive, the output data stream (530) comprising an output frame (550) may be generated such that the output frame (550) comprises a control value equal to that of the first and second input data streams (510) and payload data derived from the payload data of the frames of the first and second input data streams by processing the audio data in the spectral domain.

摘要： Transition to the logarithmic range does not require the entire bit range of the result that is linearly dependent on the square of the value. Rather, for a value having x bits, the result can be scaled in such a manner that a representation with less than x bits of the result is sufficient to obtain the logarithmic representation based thereon. The effect of the scaling factor on the resulting logarithmic representation can be cancelled by adding a correction value obtained by using the logarithmic function on the scaling factor to or subtracting it from the scaled logarithmic function without dynamic loss. The invention provides a method and a device for producing a representation of a calculation result that is linearly dependent on the square of a value, thereby allowing to carry out the calculation easily or with little hardware.

摘要： The idea underlying the present invention is that when the position of an object (10) on a surface is determined it is also possible to use transport devices for the transport of the object on the surface, said devices resulting in fewer reproducible transport movements, since the control is carried out directly based on the observed movement in relation to the desired movement. Working examples relate to the use of compressed air, magnetization and/or flexural waves.

摘要： The invention relates to a method for producing a scalable data stream from one or more blocks of output data of a first encoder and from one or more blocks of output data of a second encoder. According to this method, a destination data block (306) is written for a current section of an input signal. In addition, output data (312) of the second decoder that represents a preceding section of the input signal is written, in a direction of transmission, from an encoder to a decoder behind the destination data block (306). When the output data (312) of the second encoder is written for a preceding section of the input signal, the output data (310) of the second encoder that represents the current section of the input signal is written. In order to indicate where the output data of the second encoder for the preceding section ends, and where the output data of the second encoder for the current section begins, buffer information (314) is written into the scalable data stream. In order to provide that output data of a preceding section follows a destination data block for the current section, a bit bank function can be implemented in the scalable encoder and can be easily indicated in the bit stream.

摘要： According to the invention, the manipulation of audio data can be simplified, such as, for example, with relation to the combination of individual audio channels to give multi-channel audio data streams, or for the general manipulation of an audio data stream, whereby a data block is modified (56) in an audio data stream (10), divided into data blocks (10a, 10b) with determining blocks (14, 16) and data block audio data (18) such as, for example, by inclusion in, addition to, or replacement of a part thereof, itself containing a length indicator which expresses a data amount or length of the block audio data, or a data amount or length of the data block, such as to give a second audio data stream with modified data blocks. Alternatively, an audio data stream (10) with pointers in determining blocks (14, 10), which point to the determining block audio data (44, 46), allocated to the determining blocks, but distributed in various data blocks, is converted into an audio stream, whereby the determining block audio data (44, 46) are combined to give coherent determining block audio data (48). The coherent determining block audio data (48) can be contained with the corresponding determining block (14, 16) in a self-contained channel element (52a).

摘要： The device has computation result presented in non-logarithmic x-bit representation and processing mechanism (24) to accomplish processing (38) of non-logarithmic x-bit representation of value (22 1,22N) in order to receive computation result that depends linearly on value. Processing mechanism is arranged to use effective scaling factor so that computation result is scaled. Computation result is scaled depending on effective scaling factor. Logarithmic mechanism is for applying logarithmic function to y-bit representation (26) of non-logarithmic computation result in order to receive scaled logarithmic representation (30) of computation result. Y is smaller or two times x. Re-scaling mechanism (32) is for adding or subtracting (44) correction value to or from scaled logarithmic representation to which logarithmic function, applied to effective scaling factor, corresponds in order to produce logarithmic representation (34) of computation.
