Embodiment Construction

[0022] figure 1 A 3D menu 1 is depicted comprising three graphical elements 11 , 12 , 13 with a depth as specified by the creator of the menu 1 . The depth of the graphic elements 11 , 12 , 13 is defined relative to a reference plane 2 which is usually defined by the content creator located at a reference depth Zref from the screen plane 3 . Two control buttons 21 , 22 are provided which allow the user to increase or decrease the depth of the graphical elements 11 , 12 , 13 .

[0023] figure 2 show figure 1 The depth of the 3D menu is reduced. As can be seen, the three graphical elements 11 , 12 , 13 are arranged closer to the reference plane 2 . In addition, the difference between the z positions of the different graphic elements 11 , 12 , 13 is reduced, ie the original graphic element 11 is now arranged closer—in the z direction—to the remaining graphic elements 12 , 13 .

[0024] When depth is completely removed from menu 1, this happens as image 3 shown in . As ca...

Abstract

The present invention relates to a method for providing a stereoscopic menu (1) to a 3D display, and more specifically to a method for controlling the appearance of the stereoscopic menu (1). The invention further relates to an apparatus (4) for playback of video data and a data structure making use of such method. According to the invention, a method for controlling the appearance of a stereoscopic menu (1) during playback of video data, the stereoscopic menu (1) comprising one or more graphical elements (11, 12, 13), each graphical element (11, 12, 13) being arranged at a certain depth (Znominal), has the steps of: - receiving a user input (20) to reduce or increase a depth of the stereoscopic menu (1); and - changing (31, 41) the depth (Znominal) of each graphical element (11, 12, 13) in accordance with the user input (20).

Description

technical field [0001] The present invention relates to a method for providing a three-dimensional menu for 3D display, and more particularly to a method for controlling the appearance of the three-dimensional menu. The invention also relates to a device for playing back video data and a data structure using said method. Background technique [0002] Graphics are now very common on-screen menus. For example, DVDs (Digital Versatile Discs) or BDs (Blu-ray Discs) often include on-screen menus. During playback of a movie, the user may occasionally want to open a pop-up menu. These menus typically enable selection of another audio track, another subtitle track, jumping to another section, and so on. Also televisions often include on-screen menus, for example for switching between different video sources or changing specific settings of the television. [0003] In addition to the 2D video devices described above, stereoscopic or 3D devices are becoming more and more popular. ...
