Publication number: 20110123167Abstract: It is desired to link photo data and video data taken by a digital camcorder. Therefore, there is provided a device and method for linking multimedia data, wherein linking information is formed on the basis of first and/or second multimedia data. The linking information is stored on a recording medium together with the first multimedia data. The second multimedia data may be stored together with respective linking information to the first multimedia data on a second recording medium. Thus, a camera-man while recording is able to set up logo or index pictures for a video film.Type: ApplicationFiled: June 21, 2003Publication date: May 26, 2011Inventors: Hui Li, Dirk Adolph, Meinolf Blawat, Jobst Hörentrup, Uwe Janssen, Wolfgang Klausberger, Axel Kochale, Stefan Kubsch, Harald Schiller, Ralf Ostermann, Hartmut Peters, Marco Winter

Patent number: 7949958Abstract: Optical disc players are today connectable to the Internet, and may contain local storage capability, e.g. HDD. Additional post-production content can be downloaded and locally stored. It is difficult to include downloaded additional post- production material in menus for keeping a menu always consistent with the actually available data. Ideally, the menu should reflect the available data even if certain content is deleted or replaced with e.g. another version. A ‘linked-list’ approach for menu pages generates a dynamic menu structure. The menu consists of basic menu pages, which are retrieved from the disc, and additional pages that are downloaded together with the additional content. Page ranges may be reserved for e.g. audio, video or subtitles. The linked-list is implemented by an implicit link from each page to the next higher or lower page number.Type: GrantFiled: November 22, 2004Date of Patent: May 24, 2011Assignee: Thomson LicensingInventors: Dirk Gandolph, Jobst Hoerentrup, Ralf Ostermann, Hartmut Peters, Carsten Herpel

Patent number: 7929791Abstract: 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: GrantFiled: December 2, 2010Date of Patent: April 19, 2011Assignee: Thomson LicensingInventors: Dirk Gandolph, Jobst Horentrup, Axel Kochale, Ralf Ostermann, Hartmut Peters

Patent number: 7924916Abstract: MPEG video uses motion compensated prediction for coding pictures. A GOP includes at least one intra-coded picture to start decoding with and a number of inter-coded pictures and normally also includes bi-directionally predicted pictures. However, the GOP structure is not constructed for playing GOPs in backward direction in a trickplay mode across GOP boarders. The invention facilitates, for different GOP structures, a smooth backward video mode thereby reducing the required number of frame buffers and achieving near real-time speed presentation. In some embodiments some I and/or P pictures are decoded more than once. The invention also allows backwards decoding of MPEG-4-AVC GOPs including B-stored pictures.Type: GrantFiled: August 25, 2005Date of Patent: April 12, 2011Assignee: Thomson LicensingInventors: Dirk Adolph, Carsten Herpel, Jobst Hörentrup, Uwe Janssen, Ralf Ostermann, Hartmut Peters, Andrej Schewzow, Marco Winter

Patent number: 7921377Abstract: A method for generating an interactive electronic menu on a display, the menu comprising menu items, wherein a menu item may be in a deselected, selected or activated state, and the menu being coded into a menu data segment, comprises that at least a first and a second menu item are connected by a parent-child relationship, wherein the second menu item being a child of the first menu item can only be selected when the first menu item is selected, and further comprises that the first and the second menu item are coded into the same data segment. The method is preferably usable for menus relating to content of digital storage media, such as optical discs, in particular read-only Blu-ray discs.Type: GrantFiled: September 11, 2004Date of Patent: April 5, 2011Assignee: Thomson LicensingInventors: Dirk Gandolph, Jobst Hoerentrup, Ralf Ostermann, Hartmut Peters, Carsten Herpel

Publication number: 20110044662Abstract: Embodiments of the invention include a subtitling format encompassing elements of enhanced syntax and semantic to provide improved animation capabilities. The disclosed elements improve subtitle performance without stressing the available subtitle bitrate. This will become essential for authoring content of high-end HDTV subtitles in pre-recorded format, which can be broadcast or stored on high capacity optical media, e.g. the Blue-ray Disc. Embodiments of the invention include abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, a method includes using one or more superimposed subtitle layers, and displaying only a selected part of the transferred subtitles at a time. Further, colors of a selected part of the displayed subtitles may be modified, e.g. highlighted.Type: ApplicationFiled: May 14, 2010Publication date: February 24, 2011Inventors: Dirk Gandolph, Jobst Hörentrup, Ralf Ostermann, Hartmut Peters, Harald Schiller

Patent number: 7715685Abstract: The handling of large amounts of data on storing media shall be simplified. Therefore, a method for maintaining a storage media by generating, editing or reading log data related to the content and usage of a data item stored or to be stored on a storage medium is provided. Data items are deleted or recommendations for deletion are provided on the basis of the log data from the storage medium. Thus, the user is relieved from the unpleasant and time-consuming task of deleting data items from recording media.Type: GrantFiled: March 28, 2003Date of Patent: May 11, 2010Assignee: Thomson LicensingInventors: Dirk Adolph, Stefan Kubsch, Marco Winter, Meinolf Blawat, Hui Li, Harald Schiller, Wolfgang Klausberger, Ralf Ostermann, Axel Kochale, Hartmut Peters, Uwe Janssen, Jobst Hörentrup

Publication number: 20100095244Abstract: Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are “unselected”, “selected” or “activated”. According to the invention, the representation of a menu button may vary, depending on its state. An image or an image sequence, e.g. cartoon, may be associated to a buttons state, providing user animation. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. A data structure is disclosed which allows storage of such menu data e.g. on a Blu-ray disc.Type: ApplicationFiled: December 10, 2009Publication date: April 15, 2010Inventors: Jobst Hörentrup, Dirk Adolph, Ralf Ostermann, Harald Schiller, Hui Li
