Method and device for composing a menu

摘要

Multimedia content of exchangeable storage media, such as optical discs, may be extended by bonus content that is downloaded via Internet connection and stored on a local storage device. An improved method for integration of different menu items relating to on-disc content and downloaded content provides flexibility and a simple, low cost solution. The method for integration of downloaded bonus content into a menu comprises defining one or more placeholders within a menu, determining a storage location or naming convention for bonus content, declaring for each placeholder an attribute providing a unique association to a specific type of bonus content, providing a button image, detecting presence of bonus content data, replacing the associated placeholder by the associated button image and enabling an associated action to be taken when said button is selected.

1. A device for automatically composing an audio-visual menu for selection of playback of audio-visual data,
the menu containing buttons for selecting portions of the audio-visual data, wherein a first portion of audio-visual data and a first portion of menu data are retrieved from a first storage medium being an exchangeable pre-recorded storage medium, and wherein a second portion of audio-visual data and a second portion of menu data are obtained from a second data source and has at least one first attribute associated, the device comprising:
a processor configured to generate an initial menu from the first portion of menu data, wherein the first portion of menu data comprises audio-visual data, the initial menu containing one or more visible, selectable buttons and at least one invisible placeholder that cannot be selected, wherein the placeholder has at least one second attribute associated; a processor configured to extract said first attribute associated with the second portion of menu data; a processor configured to compare said extracted first attribute with the second attribute associated with the placeholder and for indicating that both attributes match; and a processor configured to replace upon said indication the placeholder in said initial menu with a visible and selectable menu button; a local storage, the local storage being the second data source; wherein the second data source is different from said first storage medium and wherein data obtained from the second data source are logically connected to a file system of a data from the first storage medium, and wherein said second portion of audio-visual data comprises no menu data, and said second portion of menu data comprises audio-visual menu data and navigation chaining information, wherein navigation chaining information defines a button to be selected next upon a user input of one of “UP”, “DOWN”, “LEFT” and “RIGHT” keys on a remote control.
