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 method for automatically composing an electronic audio-visual menu for selection of playback of audio-visual data, wherein a first portion of audio-visual data and a first portion of menu data is retrieved from a first storage medium being an exchangeable pre-recorded medium and wherein a second portion of audio-visual data and a second portion of menu data are obtained from a second data source, the second data source being a local storage in a playback device wherein said second portion of menu data has at least one first attribute associated and wherein said second portion of menu data contains command data and button image data and wherein said second portion of menu data contains navigation chaining information, the method comprising the steps of
logically connecting the audio visual data and menu data from the second data source to a file system of the audio visual data and menu data from the first storage medium; generating 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 with said placeholder; extracting said first attribute associated with the second portion of menu data; comparing said extracted first attribute with said second attribute associated with the placeholder; and based on said comparison, if both attributes match, replacing the placeholder with a visible and selectable button defined by the second portion of menu data, wherein a second data source is different from said 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 wherein said 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.
