Abstract: In order to create a data gathering/data processing device for video/audio signals which includes a plurality of signal processors and which has an optimized hardware architecture, it is provided that the signal processors or a subset of the signal processors are coupled to a network having a star-shaped topology.

Abstract: A method for recording video/audio data generated by a capturing device including a data memory provides connecting the data memory of the capturing device to at least one recording device that is provided with a greater storage capacity than the data memory of the capturing device, and exchanging data between the data memory and the at least one recording device such that a virtual data memory is created for the capturing device by means of the recording device.

Abstract: In order to provide a recording method for data which have been or are being generated at a data source in a time sequenced manner and are transmitted via a digital network to at least one recording device for storage, by means of which method the data can be reliably recorded, it is provided that the data are stored at the data source before the transmission on the digital network in such a way that, after a fault on the digital network, data which were intended for transmission during the period of the fault can be made available to the at least one recording device.

Abstract: A method of coding digital image data of an original image for transmission and reproduction. The original image is subdivided into partial image regions whose shapes are adapted to local image structures. For each partial image region, a set of two-dimensional, lineraly independent basis functions is provided. The areal expanse of the basis functions approximately corresponds to the size of a rectangle circumscribing the partial image region to be coded and the raster of the sampled values of the basis functions corresponds to the pixel raster of the original image. The sampled values of the basis functions disposed within the area defined by the partial image region are orthogonalized in order to obtain a set of new, orthogonal basis functions, with the set including as many orthogonal basis functions as there are pixels within the partial image region. Coefficients of the orthogonalized basis functions describing the partial image region are then calculated.
