Abstract: Apparatus for interference patterning of a planar sample including a laser and a focusing arrangement positioned in a beam path of the laser so that the laser beam is imaged in a first spatial direction in a focused manner into a sample volume in which the planar sample is positioned. An expanding and splitting arrangement is positioned downstream of the focusing arrangement for the laser beam, whilst maintaining the focused imaging in a first spatial direction which can be expanded in a second spatial direction, and which can be split into two partial beams. These two partial beams can be directed onto the sample volume.

Abstract: A transport stream provider for providing a plurality of transport stream packets describing digital media information is configured to provide a transport stream packet of a first packet type including a program association table and key information for decrypting encrypted media information. The program association table contains an association between a program No. and a packet type identifier of a further transport stream packet of a second packet type. The transport stream provider is configured to provide a transport stream packet of the second packet type in such a manner that the transport stream packet of the second packet type contains a reference to packet type identifiers of transport stream payload data packets which describe contents of different content types of the digital media information.

Abstract: A multi-dimensional representation of an object is obtained in that first and second pictures of the object illuminated using an X-ray source are created using a sensor that is located, in relation to the X-ray source, behind the object in a preferential direction defined by the relative positions of the object and of the sensor. A distance in the preferential direction between the X-ray source and the object is different in the first picture than in the second picture. The multi-dimensional representation of the object is obtained by combining the first and second pictures.

Abstract: An audio encoder for encoding an audio signal has a first coding branch, the first coding branch comprising a first converter for converting a signal from a time domain into a frequency domain. Furthermore, the audio encoder has a second coding branch comprising a second time/frequency converter. Additionally, a signal analyzer for analyzing the audio signal is provided. The signal analyzer, on the hand, determines whether an audio portion is effective in the encoder output signal as a first encoded signal from the first encoding branch or as a second encoded signal from a second encoding branch. On the other hand, the signal analyzer determines a time/frequency resolution to be applied by the converters when generating the encoded signals. An output interface includes, in addition to the first encoded signal and the second encoded signal, a resolution information identifying the resolution used by the first time/frequency converter and used by the second time/frequency converter.

Abstract: A time-of-flight 3D imaging system comprising a detector for detecting electromagnetic radiation is constructed so that the detector includes a semiconductor substrate of a first doping type, and a well in the semiconductor substrate, the well being of a second doping type. The first doping type and the second doping type are different and the well has an increasing dopant concentration in a direction parallel to a surface of the semiconductor substrate. In addition, the detector includes a detector terminal doping region which is arranged at least partly in the well in a terminal region of the well. The detection of electromagnetic radiation is based on a generation of free charge carriers by the electromagnetic radiation in a detection region of the well. The detection region has a maximum dopant concentration which is lower than a maximum dopant concentration of the terminal region of the well.

Abstract: An apparatus for encoding includes a first domain converter, a switchable bypass, a second domain converter, a first processor and a second processor to obtain an encoded audio signal having different signal portions represented by coded data in different domains, which have been coded by different coding algorithms. Corresponding decoding stages in the decoder together with a bypass for bypassing a domain converter allow the generation of a decoded audio signal with high quality and low bit rate.

Abstract: A favorable merging or grouping of simply connected regions into which the array of information samples is sub-divided, is coded with a reduced amount of data. To this end, a predetermined relative locational relationship is defined enabling an identifying, for a predetermined simply connected region, of simply connected regions within the plurality of simply connected regions which have the predetermined relative locational relationship to the predetermined simply connected region. Namely, if the number is zero, a merge indicator for the predetermined simply connected region may be absent within the data stream. In other embodiments, spatial sub-division is performed depending on a first subset of syntax elements, followed by combining spatially neighboring simply connected regions depending on a second subset of syntax elements, to obtain an intermediate sub-division.

Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

Abstract: An apparatus for intra predicting a block to be predicted of a picture from neighboring image samples sequentially extending along two rays starting at a common intersection point and pointing into different directions, the neighboring image samples including edge neighboring samples bordering the block to be predicted, includes a smoothing filter and a determiner. The smoothing filter is configured to one-dimensionally filter the neighboring image samples, which are sequentially arranged into a sequence by anti-parallelly traveling along a first one of the two rays and parallelly traveling along a second one of the two rays to obtain a filtered image sample sequence. The determiner is configured to determine a prediction value for a predetermined image sample of the block to be predicted by using the filtered image sample sequence.

Abstract: An encoder, based on a combination of two audio channels, obtains a first combination signal as a mid-signal and a residual signal derivable using a predicted side signal derived from the mid signal. The first combination signal and the prediction residual signal are encoded and written into a data stream together with the prediction information. A decoder generates decoded first and second channel signals using the prediction residual signal, the first combination signal and the prediction information. A real-to-imaginary transform may be applied for estimating the imaginary part of the spectrum of the first combination signal. For calculating the prediction signal used in the derivation of the prediction residual signal, the real-valued first combination signal is multiplied by a real portion of the complex prediction information and the estimated imaginary part of the first combination signal is multiplied by an imaginary portion of the complex prediction information.
