The socket is constructed in such a way that the corresponding contact elements are mounted at the socket along a curved line such that the electrical plug when inserted into the socket will be bent in the form of the curved line. The proposal further concerns a flexible electrical plug having two or more electrical contact elements positioned along a longitudinal axis wherein the contact elements are constructed in a flexible material.

Abstract: Audio signals are recorded with microphones receiving acoustic information from one or more directions. The corresponding audio signals can be pre-listened to in production studios. However, Higher Order Ambisonics (HOA) audio signals are matrixed in such a way that the matrixing prevents listening to the matrixed sound signals without dematrixing the matrixed sound signals. For enabling a sound engineer to listen to such a matrixed signal without full HOA decoding, an informative audio signal is added together with related side information data at encoding side to a selected part of the matrixed signal. This informative audio signal is removed before the inverse matrixing process at decoding side.

Abstract: An optical microphone comprises a light source configured to emit a light beam and an acoustic sensor configured to reflect the light beam. The acoustic sensor includes single-wall nanotubes and deflects in response to pressure waves. An optional reflector of the optical microphone is configured to re-reflect the light beam from the acoustic sensor. A detector is configured to detect the light beam from the acoustic sensor or the reflector, and thus measures the pressure waves.

Abstract: A method and an input-output device are proposed for rendering content. Further, a servicing device is proposed for delivering pre-rendered content. For rendering, a portion of processing or memorizing resources of said input-output device is allocated such that remaining resources of said input-output device are sufficient for maintaining the input-output capability of the device. Then, it is determined that an amount of resources required for rendering exceeds the allocated resources and a corresponding degree of pre-rendering is determined, too. On the serving device, pre-rendering of the content according to the determined degree is performed and the pre-rendered content is delivered from the serving device to the input-output device. Since server-side rendering is limited to a required degree, bandwidth constraints can be met more easily. Furthermore, rendering occurs more distributed and can be adjusted dynamically, thus, response time can be reduced.

Abstract: Method for describing the composition of audio signals, which are encoded as separate audio objects. The arrangement and the processing of the audio objects in a sound scene is described by nodes arranged hierarchically in a scene description.

In a further embodiment a mapping of the coordinates is performed, which enables the movement of a graphical object in the screen plane to be mapped to a movement of an audio object in the depth perpendicular to said screen plane.

Abstract: A method and an apparatus for storing data as a coded two-dimensional pattern of pixels on a photographic medium are described. An image representative of the data to be stored is divided into a two-dimensional array of blocks. A representative color value is determined for each block to obtain a two-dimensional array of representative color values. At least part of the data to be stored is coded such that the resulting coded two-dimensional pattern of pixels resembles the two-dimensional array of representative color values. The coded two-dimensional pattern of pixels is printed onto the photographic medium.

Abstract: A parametric description describing the wideness of a non-point sound source is generated and linked with the audio signal of said sound source. A presentation of said non-point sound source by multiple decorrelated point sound sources at different positions is defined. Different diffuseness algorithms are applied for ensuring a decorrelation of the respective outputs. According to a further embodiment primitive shapes of several distributed uncorellated sound sources are defined, e.g. a box, a sphere and a cylinder. The width of a sound source can also be defined by an opening-angle relative to the listener. Furthermore, the primitive shapes can be combined to do more complex shapes.

Abstract: In the MPEG-4 standard ISO/IEC 14496:2001 several audio objects that can be coded with different MPEG-4 format coding types can together form a composed audio system representing a single soundtrack from the several audio substreams. In a receiver the multiple audio objects are decoded separately, but not directly played back to a listener. Instead, transmitted instructions for mixdown are used to prepare a single soundtrack. Mixdown conflicts can occur in case the audio signals to be combined have different channel numbers or configurations. According to the invention an additional audio channel configuration node is used that tags the correct channel configuration information items to the decoded audio data streams to be presented. The invention enables the content provider to set the channel configuration in such a way that the presenter at receiver side can produce a correct channel presentation under all circumstances.

For the processing in different form, data from the second data section as well as data from the first data section are to be used.

Abstract: A method for calling up information about current radio and television programs wherein desired signals are transmitted together or separately with decodable additional information signals. The method includes the steps of selecting from the additional information signals that information which is directly or indirectly linked to time information. The selected information is compared with a time period which can be predetermined and within which the current time and/or the time assigned to the current program occurs. The information corresponding to this time period is then displayed on a display device of a receiving device which receives the desired signals and additional information signals.

Abstract: So that listeners can compile their radio service on an individual basis, broadcasts are classified according to the respective information content, and the broadcasts in each information class are sent in a respective data stream at parallel times. At the reception end, the data streams are simultaneously picked up, are possibly buffer-stored, and are forwarded to a reproduction device according to individual stipulations.

Abstract: For the purpose of spatial reproduction of an audio signal, the latter must be projected onto the positions of the existing loudspeakers. It is desirable in this case not to have to be fixed on a specific loudspeaker configuration for transmitting the audio signal. However, a problem here is that a multiplicity of possible combinations exists. In the method according to the invention, the sound sources (3) are interpreted as acoustic objects for the purpose of projecting them onto an arbitrary loudspeaker configuration (2). Here, an acoustic object consists in that in addition to the audio signal a sound source is assigned an item of spatial information which specifies a virtual, spatial position of the sound source. In order to reproduce an acoustic object, the spatial information of the sound source and the actual position of a loudspeaker are used to calculate the virtual distance from the sound source via the loudspeaker to the hearer (1).

Abstract: The invention relates to a storage medium on which a set of data is stored such that at least part of the set of data can be read and processed using a evaluation device, one part of the set of data being stored in a read-only memory area and another part of the set of data being stored in a read/write memory area of the storage medium. At least part of the set of data is read by means of the evaluation device and can be processed in a first processing form and at least one other processing form, each of which can be selected by means of the evaluation device, independent data in the set of data, which independent data can be used both for the at least partial processing of the set of data in the first processing form and for the at least partial processing of the set of data in the at least one other processing form, being included in the first part of the set of data, which part is stored in the read-only memory area.

Abstract: For audio coding, the MPEG-2 standard provides for a spatial representation by multi-channel reproduction. In order to ensure backwards compatibility with MPEG-1 signals, the signals of the multi-channel sound channels are matrixed. Before being matrixed, the audio signals generally have their levels reduced in order to prevent overdriving. In order to balance again the reduction at the encoder end, an option that is provided in the MPEG-2 standard is for a decoder to raise the output levels again. If, however, a transmission error then occurs in the multi-channel section, the decoder cannot carry out the reverse matrixing. In that case, only the MPEG-1-compatible signal component will be decoded. The auditory impression can therefore be disturbed in various ways during the changeover to MPEG-1 decoding.
