Publication number: 20110064130Abstract: Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time. The bitmaps are a separate layer lying above the video, e.g. for synchronized video subtitles, animations and navigation menus, and therefore contain many transparent pixels. An advanced adaptation for bitmap encoding for HDTV, e.g. 1920.times.1280 pixels per frame as defined for the Blu-ray Disc Prerecorded format, providing optimized compression results for such subtitling bitmaps, is achieved by a four-stage run length encoding. Shorter or longer sequences of pixels of a preferred color, e.g. transparent, are encoded using the second or third shortest code words, while single pixels of different color are encoded using the shortest code words, and sequences of pixels of equal color use the third or fourth shortest code words.Type: ApplicationFiled: November 29, 2010Publication date: March 17, 2011Applicant: THOMSON LICENSINGInventors: Dirk Gandolph, Jobst Hörentrup, Axel Kochale, Ralf Ostermann, Hartmut Peters

Publication number: 20110055472Abstract: The present invention relates to a redundancy protected mass storage system with increased performance, and more specifically to a mass storage system with multiple storage units. According to the invention, the resources that are essentially provided for compensating the damage of one or more storage units are also used to enhance the system performance. For this purpose during reading or writing the storage system just waits for the responses of a minimum number of required storage units to start reading or writing, respectively.Type: ApplicationFiled: August 5, 2008Publication date: March 3, 2011Inventors: Stefan Abeling, Wolfgang Klausberger, Thomas Brune, Axel Kochale

Patent number: 7656982Abstract: A bit clock recovery apparatus for digital storage readout employing sync frames, where an oversampled readout signal is stored in memory, sync patterns are located in the signal using DSP means, distances of consecutive sync pattern locations are calculated, and bit clock is recovered from these distances and the knowledge about the data framing structure.Type: GrantFiled: April 27, 2004Date of Patent: February 2, 2010Assignee: Thomson LicensingInventors: Klaus Gaedke, Friedrich Timmermann, Axel Kochale, Ralf-Detlef Schaefer, Herbert Schütze, Marten Kabutz

Patent number: 7640228Abstract: A method for modifying data read from read-only media during playback time comprises logically merging the on-disc directory tree and an associated off-disc directory tree. A logical directory tree is constructed from the data retrieved from the read-only medium, wherein the structure of the logical directory tree is identical with the structure of the directory tree of the medium. The method allows replacing content on the disc through downloaded content, e.g. replacing an out-dated trailer stored on the disc through a downloaded trailer for a new movie. The method further allows complementing or upgrading content on the disc, e.g. by downloading a new subtitle track from the internet.Type: GrantFiled: August 23, 2004Date of Patent: December 29, 2009Assignee: Thomson LicensingInventors: Jobst Hörentrup, Dirk Gandolph, Axel Kochale, Ralf Ostermann, Carsten Herpel

Patent number: 7623573Abstract: Compression parameter sets are stored in files separate from the main AV or transmitted separately and prior to any subsequent transmission of AV data. The scope of parameter set identifiers is limited to not more than a Program Chain. Either existing files are extended by including the compression parameter sets directly, or separate files containing the compression parameter sets are created. In order to support easy authoring of compound content, it is proposed to amend each compression parameter set or groups of such parameter sets with scope period information, which can be based on time stamps, on file names, or on sector numbers on the disc. It is additionally proposed to employ an indirect referencing mechanism, where parameter set identifiers are referring to secondary tables, and where the entries of secondary tables are defined to be themselves identifiers referring in turn to entries of a common parameter set table provided once.Type: GrantFiled: July 12, 2003Date of Patent: November 24, 2009Assignee: Thomson LicensingInventors: Carsten Herpel, Harald Schiller, Ralf Ostermann, Edgar Peters, Axel Kochale

Patent number: 7613023Abstract: When recording uncompressed video and/or audio data using a digital video recorder, there is the need for a robust memory arrangement based on non-volatile, integrated circuits which is able to be fitted directly on the video camera without a long external cable connection and which is also able to be used for shots under difficult conditions, particularly action shots. The inventive memory arrangement involves the use of a number of non-volatile memory chips which are connected together with a favorable level of circuit complexity. To be able to cope with the high data rate for the incoming video and/or audio data, a plurality of parallel supply buses are provided. Each supply bus has an associated number of memory chips. In this case, the memory word length of the memory chips is greater than the bus width of a data/address bus.Type: GrantFiled: February 21, 2006Date of Patent: November 3, 2009Assignee: Thomson LicensingInventors: Michael Drexler, Axel Kochale, Jens Peter Wittenburg

Publication number: 20090059737Abstract: In a storage medium, an address space is defined which is divided into a first area and a second area. According to the invention, at least one file is stored on the medium which is split into small data packets and large data packets. All small data packets are stored on said first area, and all large data packets are stored on said second area. A single file allocation table (FAT) is used and is small by having one entry per data packet.Type: ApplicationFiled: August 28, 2008Publication date: March 5, 2009Inventors: Johann Maas, Axel Kochale, Stefan Abeling

Patent number: 7496282Abstract: The invention relates to an MPEG video recording medium and a reproduction apparatus for the reconstruction of missing data sequences of a video data stream. Scratches and other defects of the recording medium cause interruptions or disturbances in the data stream read from the recording medium, which can be corrected only to a limited extent by conventional error correction methods, such as the Reed-Solomon Code, for example. Therefore, an MPEG video recording medium is provided on which, with respect to an original I frame, at least one copy or a similar I frame is recorded on the recording medium for the reconstruction of missing or erroneous data sequences of a video data stream. The replacement I frames are arranged in the outer area, intermittently or within a predetermined area in the program area on the recording medium and do not influence the reproduction of the recording medium on conventional reproduction apparatuses.Type: GrantFiled: December 9, 2002Date of Patent: February 24, 2009Assignee: Thomson LicensingInventor: Axel Kochale
