Abstract: For selectively accessing data elements in a data library, an image data object which can be shown on a display is provided. A plurality of image subobjects are defined which respectively correspond to a portion of a representation of the image data object. The data elements are associated with at least a respective one of the image subobjects. One of the image subobjects is selected from a representation of the image data object on the display. The data elements which are associated with the selected image subobject are then reproduced. A data object which comprises the data elements in the data library, the image data object and the association between the data elements and the image subobjects is transmitted to a communication terminal via a telecommunication network for the purpose of selectively accessing the data elements.

Abstract: Method for anonymously transmitting a message by means of a telecommunication network. A first exchange (2) between the sender (1) and the receiver (4) of said message replaces identifying features (MSISDN) of the sender (1) of the message by a first alias identification (CID). The conversion between the said identifying features (MSISNDN) and the first alias identification (CID) is permanent, or at least secure for several weeks. The first alias identification (CID) is replaced by a second alias identification (CMID) at the receiver (4) or in a further exchange (3). The second alias identification (CMID) enables the receiver to identify the transmitter.

Abstract: A method is disclosed for centrally storing data in a remote server (4). On the remote server (4), a voice memo (42) that has been recorded by a user (1) and converted into a text with the aid of a voice recognition system (13, 43) is stored as a text. The memory area (42) is user-specific, and the user (1) is previously identified in the remote server (4). Simultaneously, the contents of the memory area (42) can be searched by the user (1) for a particular item of information. The invention is characterized in that additional data are transmitted over an interface (14, 24) working at close range to a telecommunication device (11) of the user (1) and over the telecommunication device (11) to the remote server (4), and additionally stored in the memory area (42) allocated to the user (1). The invention also relates to a remote server (4) with equivalent characteristics.

Abstract: The invention relates to an authorization verification method and devices suited therefor, which play back authorization data via a user interface (11) of an electronic playback device (1). During the playback of authorization data via the user interface (11) of a first playback device (1), the playback attributes are modified. The playback of authorization data via the user interface (11) of the first playback device (1) is compared with the playback of reference data via a user interface (21) of a second electronic playback device (2). Authorization is granted in the event the playback of authorization data via the user interface (11) of the first playback device (1) matches the playback of reference data via the user interface (21) of the second playback device (2), and modifications of the playback attributes are, in essence, time-synchronized.

Abstract: A method and associated arrangement allows a content or service provider to establish an anonymous profile of a consumer using at least one request sent by the consumer through a communication network. The request sent by the consumer includes identification data of the consumer. The identification data is substituted in the network with an alias so as to anonymize the request. The identification data is not accessible to the content or service provider and there is a one-to-one and immutable correspondence between the identification data and the alias.

Abstract: The invention relates to the problem of recycling of products of complicated structure and is based on the idea to provide each component of the product with a memory in which not only at the timing of production information such as location of material to be recycled is stored but also additional data, e.g., about repair and/or specific stress to which the component has been exposed during its use. Such additional data may be collected via specific sensors provided either on each component or in or on the body of the product to be memorized in the memory of each component. Based on the idea of the invention, the life history of each component of the discarded product can be checked individually for determining whether such component may be reused or disposed for disassembling and recycling.

Abstract: In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbered rows so that odd-numbered data and even-numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when error correction becomes impossible by the error correcting code for one row, interpolation remains feasible because there exist no odd-numbered data or even-numbered data contiguous to each other in the row.

Abstract: A sampling frequency converter converts sampled input data having an input sampling frequency into sampled output data having a different output sampling frequency. The relative ratio between input data sample periods and output data sample periods is determined and averaged over a predetermined duration. A filter coefficient generator responds to the averaged input/output sampling period ratio for generating data representing a set of predetermined filter coefficients which are used by a sampling filter circuit to convert the input data samples into output data samples of a different sampling frequency.

Abstract: Recording apparatus for forming a track on a disk-shaped recording medium capable of optical information reproduction, comprises a deflection device for deviating a recording beam from a light source in a radial direction of the disk-shape recording medium and a deflection-control signal generating device. The deflection control signal is developed from the superimposition of a first signal having a predetermined frequency and a second signal having a lower frequency than the predetermined frequency. The superimposition of the second signal can be done while retaining the predetermined frequency.

Abstract: To compensate for transmission errors of a non-ideal system for transmitting digital signals, first signal deviations are determined and stored, and then there is a direct processing of the input signals into output signals by combining the input signals with the stored signal deviations. The invention includes both method and apparatus and provides a substantial reduction in equipment costs.

Abstract: Using the inventive method and apparatus, two scanning sequences can be synchronized with small signal delays and at the smallest possible apparatus expense. The time differences between associated scanning values or signals of the two scanning sequences are compensated by alternatingly delaying relative to each other the scanned values or signals and interpolating between the scanned values or signals of one of the two scanning sequences. The apparatus for carrying out the synchronizing operation comprises a storage for producing the delays and a filtering device for performing the interpolation.

Abstract: A method of decoding digital synchronizing signals each of which consists of a plurality of bits in a predetermined pattern, the intervals between the starts of successive synchronizing signals in an input digital signal being variable over a range, comprises ascertaining the bit period distance between the starts of two successive synchronizing signals, subsequently searching the input digital signal for the pattern using a window comprising the bit period distance, which window is varied in position if the bit period distance changes, and supplying an output synchronizing pulse in synchronism with subsequent synchronizing signals found in the window.

Abstract: Digital data, such as audio data is coded by encoding apparatus, into a format of fixed-length multi-bit data words. At least one bit in the same predetermined bit position in each data word is a specific information data bit, such as channel status information or user information. A plurality of the specific information data bits from a corresponding plurality of successive data words respectively form a specific information word. Each specific information word contains a synchronizing signal, and the length of the specific information words is variable. A decoder decodes the encoded digital data.

Abstract: An input sampling sequence with an input sampling rate is translated into an output sampling sequence with a selectable output sampling rate in a sampling filter. A circuit for forming the time difference of the sampling points forms from the given input sampling rate and the desired output sampling rate a signal corresponding to the time difference and this is used in a translation circuit for converting into data for characterizing the filter coefficients. The sampling filter is conditioned by the selected coefficients from the translation circuit. The invention is suitable for the transmission of sampled data, particularly sampled rates between two systems operating at different clock frequencies.

Abstract: Methods and apparatus for recording and reproducing coded digital signals typically assign values of a signal to 2 categories which are separately coded, delayed differently, and subsequently recorded. In order to reduce the loss of such values in the cases of damage to the recording to the greatest possible extent, the values of the signals are coded at least twice in parallel and recorded onto several tracks. In one of the recordings, the sequence of values is modified in such a way that even major damage to the recording can be accommodated without producing non-correctable errors.

Abstract: In order to equalize different delays between the digital signals of two or more digital signal sequences, additional signals are added to at least one of the digital signal sequences of digital signals. The additional signals are indicative of the momentary temporal relationship between the digital signals of the different digital signal sequences.
