摘要： Devices and methods for generating encrypted data, for playing encrypted data and for re-signing originally signed encrypted data are based on the encrypted data, apart from the encrypted media information, to include the information required for decrypting the data and additionally a signature of who has generated the encrypted data. Thus the origin of the encrypted data can be traced back. In particular, passing on the encrypted data to a limited extent by the producer of the *encrypted data, for example to friends or acquaintances, is allowed, while only a mass reproduction of the encrypted data is considered as pirate copying. The pirate copier can, however, be found out with the help of the signature, wherein the signature is optionally protected by an embedded watermark signature. Because this is a concept wherein, when being used legally, only encrypted data occur, the unauthorized removal of the encryption is a statutory offence. The inventive concept makes possible finding the offender and at the same time considers ownerships of the operators with regard to a limited passing-on of media information, and thus has the potential of being accepted on the market.
摘要翻译：用于生成加密数据，用于播放加密数据和重新签署原始签名的加密数据的装置和方法基于加密数据，除了加密的媒体信息之外，还包括解密数据所需的信息，另外还包括谁的签名已生成加密数据。因此，可以追溯加密数据的来源。特别地，允许由加密数据的制作者（例如，朋友或熟人）在有限程度上传递加密数据，而仅将加密数据的大规模再现视为盗版复制。然而，在签名的帮助下，可以发现盗版复印机，其中签名可选地被嵌入的水印签名保护。因为这是一个概念，其中当被合法使用时，仅发生加密的数据，未经授权的加密删除是法定的。本发明的概念使得有可能发现犯罪者，同时考虑到运营商对媒体信息传递有限的所有权，因此具有被市场接受的潜力。

摘要： An inventive method for introducing information into a data stream including data about spectral values representing a short-term spectrum of an audio signal first performs a processing of the data stream to obtain the spectral values of the short-term spectrum of the audio signal. Apart from that, the information to be introduced are combined with a spread sequence to obtain a spread information signal, whereupon a spectral representation of the spread information is generated which will then be weighted with an established psychoacoustic maskable noise energy to generate a weighted information signal, wherein the energy of the introduced information is substantially equal to or below the psychoacoustic masking threshold. The weighted information signal and the spectral values of the short-term spectrum of the audio signal will then be summed and afterwards processed again to obtain a processed data stream including both audio information and information to be introduced. By the fact that the information to be introduced are introduced into the data stream without changing to the time domain, the block rastering underlying the short-term spectrum will not be touched, so that introducing a watermark will not lead to tandem encoding effects.

摘要： Techniques for introducing information into a data stream first obtains the spectral values of the short-term spectrum of the audio signal. Separately, information to be introduced are combined with a spread sequence obtaining a spread information signal, whereupon a spectral representation of the spread information is generated, then weighted with an established psychoacoustic maskable noise energy to generate a weighted information signal, wherein energy of the introduced information is substantially equal to or below the psychoacoustic masking threshold. The weighted information signal and the spectral values of the short-term spectrum of the audio signal are then summed and afterwards processed again to obtain a processed data stream including audio information and information to be introduced. Because the information to be introduced are introduced without changing to the time domain, the block rastering underlying the short-term spectrum are not touched, thus introducing a watermark will not lead to tandem encoding effects.

摘要： An integer transform, which provides integer output values, carries out the TDAC function of a MDCT in the time domain before the forward transform. In overlapping windows, this results in a Givens rotation which may be represented by lifting matrices, wherein time-discrete sampled values of an audio signal may at first be summed up on a pair-wise basis to build a vector so as to be sequentially provided with a lifting matrix. After each multiplication of a vector by a lifting matrix, a rounding step is carried out such that, on the output-side, only integers will result. By transforming the windowed integer sampled value with an integer transform, a spectral representation with integer spectral values may be obtained. The inverse mapping with an inverse rotation matrix and corresponding inverse lifting matrices results in an exact reconstruction.

摘要： For characterizing an information signal having an amplitude-time waveform with local extreme values, at first the local extreme values of the information signal are determined, wherein a local extreme value is defined by a time instant and an amplitude. Furthermore, area information of valleys or mountains of the information signal in case of a one-dimensional amplitude of the information signal or volume information in case of a two-dimensional amplitude of the information signal of valleys or mountains is ascertained. A valley or mountain is defined by a temporal section of the information signal, wherein the section of the information signal extends from the time instant of a local extreme value to a temporarily adjacent value of the information signal having the same amplitude as the local extreme value. Area or volume information of several mountains or valleys is characteristic for the information signal and permits further characterization of the information signal, build-up of an information signal database, or identification of an information signal on the basis of an existing information signal database. Area or volume information is on the one hand characteristic for the information signal and on the other hand, due to its integral nature, robust against information signal changes in form of overlays or distortions.

摘要： In a method of coding discrete time signals (X1) sampled with a first sampling rate, second time signals (x2) are generated using the first time signals having a bandwidth corresponding to a second sampling rate, with the second sampling rate being lower than the first sampling rate. The second time signals are coded in accordance with a first coding algorithm. The coded second signals (X2c) are decoded again in order to obtain coded/decoded second time signals (X2cd) having a bandwidth corresponding to the second sampling frequency. The first time signals, by frequency domain transformation, become first spectral values (X1). Second spectral values (X2cd) are generated from the coded/decoded second time signals, the second spectral values being a representation of the coded/decoded time signals in the frequency domain. To obtain weighted spectral values, the first spectral values are weighted by means of the second spectral values, with the first and second spectral values having the same frequency and time resolution. The weighted spectral values (Xb) are coded in accordance with a second coding algorithm in consideration of a psychoacoustic model and written into a bit stream. Weighting the first spectral values and the second spectral values comprises the subtraction of the second spectral values from the first spectral values in to obtain differential spectral values.
