  • Patent number: 10353547
    Abstract: 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.

  • Patent number: 10127671
    Abstract: A method and an apparatus for generating a superpixel cluster for an image or a sequence of images. A primary clustering unit generates a primary superpixel cluster using a fixed reference superpixel, whereas a secondary clustering unit generates two or more secondary superpixel clusters using a propagating reference superpixel. A combining unit then combines intersections between the primary superpixel cluster and the two or more secondary superpixel clusters to generate a final superpixel cluster.

  • Patent number: 9971951
    Abstract: Method and apparatus for generating superpixel clusters A method and an apparatus (20) for generating a superpixel cluster for an image are described. A clustering unit (23) generates (10) an initial superpixel cluster based on an initial cluster center. The clustering unit (23) further generates (12) one or more further superpixel clusters based on one or more further cluster centers. A determining unit (24) determines (11) the one or more further cluster centers from the initial superpixel cluster. A merger (25) then merges (13) the initial superpixel cluster and the one or more further superpixel clusters to obtain the superpixel cluster for the image.

  • Patent number: 9928574
    Abstract: A method and an apparatus for generating superpixels for a sequence of images are described. A segmenter segments an image of the sequence of images into a set of initial superpixels. A motion analyzer then determines static and non-static areas in the sequence of images. Based on an output of the motion analyzer the segmenter generates updated superpixels for non-static areas of the sequence of images, and maintains those superpixels of the set of initial superpixels belonging to static areas of the sequence of images.

  • Publication number: 20170324925
    Abstract: 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.

  • Publication number: 20170206633
    Abstract: A method and an apparatus (20) for up-scaling an input image (12) are described, wherein a cross-scale self-similarity matching using superpixels is employed to obtain substitutes for missing details in an up-scaled image. The apparatus (20) comprises a superpixel vector generator (7) configured to generate (10) consistent superpixels for the input image (12) and one or more auxiliary input images (I1, I3) and to generate (11) superpixel test vectors based on the consistent superpixels. A matching block (5) performs a cross-scale self-similarity matching (12) across the input image (12) and the one or more auxiliary input images (I1, I3) using the superpixel test vectors. Finally, an output image generator (22) generates (13) an up-scaled output image (O2) using results of the cross-scale self-similarity matching (12).

  • Patent number: 9626595
    Abstract: A method for pixel mapping between an origin superpixel in a first image and a target superpixel in a second image and an apparatus configured to perform the method. The apparatus comprises a feature vector determining unit, which determines a feature vector of an origin pixel of the origin superpixel and which further determines feature vectors of target pixels of the target superpixel. A mapping pixel selector selects a mapping pixel for the origin pixel among the target pixels based on a comparison of the feature vectors.

  • Patent number: 9529501
    Abstract: A method for generating an on-screen menu comprising menu buttons and other menu items, e.g. help text, is characterized in that one or more groups of menu buttons or menu items are defined, wherein a group comprises one or more menu buttons or menu items and has associated a defined area on the screen. A state is assigned to a button, the state being “enabled” or “disabled”, wherein only an enabled button or item may be displayed, and wherein within a group not more than one button or item may be enabled. The state of a button can be changed by commands associated with other buttons.

  • Patent number: 9509969
    Abstract: Consumer electronic devices, such as e.g. high-definition movie players for removable storage media such as optical discs, may provide possibilities for advanced interactivity for the user, implemented as software applications. A question arising generally with such software applications is what the life cycle of such an application is, and who may control it. The invention provides a method for executing software applications within a playback device for audio-video data, wherein data from a first removable storage medium are read for a software application to be executed within said playback device, and the data comprise an indication defining a termination condition for the application. Based on said termination code and depending on how the medium holding the application is ejected, the application is terminated or may survive.

According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don't have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. 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. Such menu data may be stored; e.g., on a Blu-ray disc.
