Embodiment Construction

[0041] figure 1 is a graph showing the depth Z of the stereoscopic 3D primary video stream VS over time t. In addition, the depth of the rendering range of the overlay graphic OD is shown by the dashed area. Although the minimum depth value Zv,min(t) and the maximum depth value Zv,max(t) of the video stream VS vary over time, the depth range used to render the overlay OD is constant over time. The depth range for rendering the overlay pattern OD starts at the depth Zref representing the depth value of the reference plane in z-space and ends at the minimum value Zcomfort,min of the comfort zone. In general, the rendering of video information is preferably located around the screen depth Zscreen. Preferably, the 3D video information is located inside a comfort zone defined by its minimum depth Zcomfort,min and its maximum depth Zcomfort,max in z-space.

[0042] The comfort zone needs to take into account aspects of an enjoyable 3D viewing experience. The boundaries of the co...

Abstract

A method and apparatus for creating stereoscopic 3D video information comprising a 3D video stream and 3D overlay graphics is described. A depth range in z-space for stereoscopic rendering of a three-dimensional video stream is determined for a plurality of timecodes. Then, determining a reference plane in z-space for placing the 3D overlay graphics reduces depth conflicts between the 3D video and the reference plane. A comfort zone is defined around a display screen plane and encompassing the reference plane, wherein the comfort zone specifies a range of depths in z-space for optimal rendering of stereoscopic three-dimensional video information. It is then determined for the corresponding timecode whether there is still a depth conflict between the reference plane and the 3D video stream and / or whether there is a depth conflict between the comfort zone and the 3D overlay pattern for the corresponding timecode. In this way a set of conflicting intervals stored on a media source containing a 3D video stream and a 3D overlay graphic is generated. The set of conflicting intervals is used during revisiting to adjust the rendering of the 3D video stream or the rendering of the 3D overlay graphics.

Description

technical field [0001] The present invention relates to a method and apparatus for creating stereoscopic 3D video information comprising 3D video streams and 3D overlay graphics. Furthermore, the invention relates to a method and a device for displaying such stereoscopic three-dimensional video information. Background technique [0002] With the recent box-office success of stereoscopic 3D movies, there is also hope to bring 3D video to home entertainment. One of the first available solutions was the Blu-ray 3D format. Preferably, the 3D movie is displayed inside what is called the comfort zone. The identification of comfort zones remains an active area of ​​research. In general, the comfort zone describes an interval in z-space extending from somewhere behind the screen to a minimum distance from the viewer in front of the screen. One option for determining this comfort zone is the so-called 1 / 3 diopter rule. Furthermore, the extent of this comfort zone according to th...
