摘要： Method and apparatus are described for compensating for a linear time scale change in a received signal, so as to correctly rescale the frame sequence of the received signal. Firstly, an initial estimate of the sequence of symbols is extracted from the received signal. Successive estimates of correctly time scaled sequences of the symbols are then generated by interpolating the values of the initial estimates.

摘要： The present invention relates to methods and apparatus for transfer of digital content. A method of transferring digital content from a first entity (60) to a second entity (70) includes a transfer control entity (50) transmitting a transmission key k 1 [n] to the first entity. The first entity applies the transmission key to digital content, to encrypt the digital content. The first entity transmits the encrypted digital content to the second entity. The transfer control entity transmits a receive key k 2 [n] for receipt by the second entity. The second entity applies the receive key to the encrypted digital content to generate decrypted data comprising the decrypted digital content embedded with a watermark w[n]. The transfer control entity transmits a degraded version w'[n] of the watermark to an entity for watermark detection.

摘要： The invention relates to extracting and embedding auxiliary data from and to a host signal. In an embodiment, the auxiliary data relates to remotely control of an application or a device, such as an interactive toy. Auxiliary data are extracted from a host signal, by periodically (32A-32C) with a predetermined first period searching a first section (33A-33C) of the host signal for a first watermark (34); and, upon detection of the first watermark, searching the host signal for a second watermark (35). In embodiments, information relating to timing and type of action to be performed by a remotely controlled device may be conveyed by the watermarks.

摘要： A device (1) for determining accented beats in a music signal (x[n]) comprises: energy determination means (12) for determining the energy (E[n]; E[k]) of the music signal (x[n]), - segmentation means (15) for segmenting the energy on the basis of a tempo estimate (T), similarity determination means (17) for determining the similarity between the energy (E[n]; E[k]) of segments, and selecting means (18) for selecting the segment having the smallest similarity as the segment containing an accented beat. The tempo estimate (T) may be determined by external means. The energy may be determined in the time domain or in a transform domain. The similarity may be determined using cross-correlation, entropy or a distance measure. The device (1) may advantageously be used in AutoDJ apparatus.

摘要： The invention relates to a method of searching for a watermark in a data signal, and to a watermark detector, such as a copy-control watermark detector. The search is conducted in order to find a watermark in content which possibly has been attacked and/or altered. The search is conducted by the steps of determining or setting a search space for the data signal, selecting a subspace of the search space, and searching for the presence of the watermark in the subspace. The subspace may be selected from a multitude of regions, the selection e.g. being based on a deterministic or probabilistic function.

摘要： Disclosed are a method and a system for secure watermark embedding in a server-client configuration (60,70). The method comprises encrypting (210) the data signal (x) and generating (240) a decryption key wherein a watermark (W i ) is included. The client decrypts (420) the encrypted data signal in order to obtain a watermarked data signal (x w ). In accordance with the invention, the encryption mechanism and decryption key are made dependent on a perceptual mask (m 1 ,m 2 ) so as eventually make the embedded watermark more robust.
