A method for hierarchical disparity estimation on an image pair, wherein image pyramids are created by successively downscaling each image of the image pair, and an apparatus configured to perform the method are described. An initial disparity estimator applies a full search on a highest level of the image pyramids to determine initial disparity estimates, the highest level having the lowest resolution. A disparity propagator passes the initial disparity estimates to a next lower level of the image pyramids. An allocator then partitions the pixels of each remaining hierarchy level of the image pyramids into two or more groups of pixels, where each pixel in a group of pixels can be processed independently from remaining pixels of that group of pixels. A disparity estimator estimates disparity values for the pixels of a first group of pixels utilizing disparity estimates from a next higher level of the image pyramids. The disparity estimator further estimates disparity values for the pixels of remaining groups of pixels utilizing disparity estimates from a previously processed group of pixels in that hierarchy level.

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.

Local storage on player instruments provides the ability for adding further amendments and most recent supplements to the optical disc content. A problem arising with this technically applicable possibility is the protection of copyrights bound to disc and supplement data. The present invention describes a technique to ensure a security framework that is able to handle this, by creating a virtual file system (VFS) by merging optical disc data and local storage data based upon a common identifier.

Bonding contents on separate storage media

A method for generating multi-language menus comprises grouping language-dependent menu resource files on a storage medium, and selecting only those menu resource files from a group that are labeled with an indication that matches the preferred menu language of the respective player.
