摘要： In an apparatus and a method for reproducing user data stored in encrypted form on a recording medium, in order to provide a higher level of protection against hacking of user data and, in particular, of decryption keys, which are used for encrypting said user data and which are also stored on the recording medium, an integrated unit calculates a decryption key using key data read from the recording medium, decrypts the user data read from said recording medium using the calculated decryption key, andre-encrypts the decrypted data using a re-encryption key. The re-encrypted data and the re-encryption key are then transmitted to an application unit for decrypting the re-encrypted data using the re-encryption key and for reproducing the decrypted data.

摘要： Methods and arrangements for processing a signal using a digital processor having a given word length. The signal is pre-processed using a pre-processor which reduces the word length and performs an operation which is invariant with respect to a process being performed by the digital signal processor. This means that if the pre-processor operated with infinite accuracy, it would have no effect on the subsequent process. If such a pre-processor operates with infinite accuracy, it will reduce the guantization noise. In the digital signal processor, the pre-processed signal may be transformed into frequency coefficients which are normalized directly thereafter.

摘要： Proposed is an illumination system (100) comprising a plurality of light sources (10) provided with encoders (20) arranged to enable light emitted from the light sources to comprise light source identification codes. In order to enable light effect commissioning, i.e. correlating the light sources (10) with their illumination footprints (11), the system further comprises a camera (40) arranged to register images of illumination spots (11), and a signal processor (111) arranged to derive the light source identification codes from registered images. Arranging the encoders (20) to modulate the light emitted at a frequency above a predefined high level to comprise fast codes (12) and at a frequency below a predefined low level to comprise slow codes (13), beneficially allows for the use of simple low cost camera systems.

摘要： Coded light has been proposed to enable advanced control of light sources and transmit information using light sources. It is based on invisibly embedding of data and identifiers in their light output. Methods, devices and systems configured to efficient assignment of addresses in a coded lighting system, still allowing for unique identification, are proposed. More specifically, the assignment of addresses occurs in two phases, where in the initial phase wide area unique addresses are used, while in the second phase only local area unique addresses are used. Also, methods, devices and systems configured to efficiently distribute a set of addresses over a set of light sources in this second phase, to maximize the performance of the illumination contribution estimation, and positioning, are disclosed.

摘要： In summary, the invention relates to a device, a system, a method and a computer program for spectrum sensing. A detection procedure for detecting a signal of interest or an event by using a plurality of sensing devices capable of communicating with a central unit is proposed. The sensing devices can compute soft detection metrics and communicate this information to a central unit, where the information may be used to make a final detection decision using a certain specified rule. The signaling overhead of the proposed approach can be of the same order as that of a hard signaling approach. However, the proposed approach may achieve a better detection performance.

摘要： A method of and device (110) for granting access to content on a storage medium (101), comprising obtaining cryptographic data (Y) from a property (102), such as a wobble, of the storage medium (101), reading helper data (W) from the storage medium (101), and granting the access based on an application of a delta-contracting function to the cryptographic data (Y) and the helper data (W). The delta-contracting function allows the choice of an appropriate value of the helper data (W), such that any value of the cryptographic data (Y) which sufficiently resembles said original primary input value leads to the same output value. Substantially different values of the cryptographic data (Y) lead to different values of the output.
