Abstract: A method is suggested enabling a person that watches a TV broadcasted live event to select and associate in a simple manner to the displayed video, an audio stream dealing with the same event but delivered by another source than the TV channel. The method relies on techniques allowing to know and to decode some available audio streams that deal with the same live event as the one currently displayed on TV and to synchronize these audio streams with the TV channel.

Abstract: A Braille display system and a method for operating a refreshable Braille display 14 is provided. A string of characters is assigned to a drive signal for specifying the activation or deactivation of a tuple of dots which are raised through holes in a touch and sense surface of the Braille display 14 upon activation and which are retracted upon deactivation.

Abstract: The device comprises an aperture stop disc divided into a plurality of mutually exclusive filtering segments comprising a first, a second and a third filtering segment; the third filtering segment is adapted to pass a third portion of the spectrum which is included in the portion of the spectrum passing the first and second filtering segments. Due to third filtering segment, the aperture assigned to the color component corresponding to the third portion of the spectrum—preferably blue—is larger than the aperture assigned to the color component corresponding to the portion of the spectrum passing the first and second filtering segments.

Abstract: A method and an apparatus for archiving an image on a photographic medium are described. The image consists of an array of pixels, where a color depth of the pixels is n bits. In addition to recording the array of pixels on the photographic medium also a subset of the n bits describing the color of the pixel is recorded on the photographic medium for each pixel.

Abstract: A receiver comprises a security processor and a first memory that stores software code or second stage authentication key and a signature for the software or the second stage key. The receiver also stores a plurality of verification keys (PUAK). When the receiver is switched on or reset, the software or second stage key and the signature are loaded from the first memory. The security processor then loads a PUAK and uses it to verify the signature. In case of successful verification, the software code or second stage key is used and the verification method ends; it is then possible to activate CA specific functions in the receiver. However, if the verification is unsuccessful, then it is verified if there are untried PUAKs. If there are no untried signatures, then the verification has failed and the software cannot be verified; the verification method ends. If there are untried signatures, then the next PUAK is loaded.

Abstract: A method and an apparatus for processing occlusions in motion estimation are described. For processing an occlusion in a forward motion field of a second frame relative to a first frame the forward motion field of the second frame relative to the first frame is determined with a motion estimator. Then an area in the second frame that is occluded in the first frame is identified with an occlusion identifier. Finally, a motion corrector determines a corrected forward motion field by filling the forward motion field in the identified area in the second frame using motion vectors of a previous backward motion field of the second frame relative to a previous third frame.

Abstract: A method and an apparatus for visualizing data sets comprising a defined number of elements, which are subject to a temporal process, are described. After determining a number of displayable clusters of spatially adjacent elements of the data set at least part of the elements of the data set are retrieved. The retrieved elements of the data set and the not yet retrieved elements of the data set are clustered into the determined number of clusters, wherein the not yet retrieved elements of the data set are represented using placeholders. After assigning a value to each cluster, the value of each cluster is visualized on the display. Whenever one or more elements of the data set are modified and/or whenever one or more further elements of the data set are retrieved, the clusters, the assigned values and the visualization on the display are updated.
