Blu-ray 3D Playback Configuration via Device Plane Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Blu-ray standards do not specify how to record or play 3D image content, leading to unsuitable playback of 3D image contents, especially when authored by creators who are not experts in this process.
Innovation Solution
An information processing device and method that configures storage regions for left and right eye images, defining modes for graphics, video, and background images to ensure suitable playback of 3D content, including mono, stereo, offset, and flattened stereo modes, with an API for setting these configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D image content is recorded on Blu-ray disc without standardized configuration, then large-capacity recording medium is utilized, but playback suitability deteriorates
Solution Approach 1:
The patent applies parameter changes by defining specific playback configuration parameters including device plane configuration (collateral arrangement of L and R regions), storage region allocation (separate L region and R region for left and right eye images), and playback mode settings (mono, stereo, offset, flattened stereo, forced mono). These standardized parameters ensure reliable 3D content playback while managing configuration complexity through systematic definition.
Solution Approach 2:
The patent segments the storage structure into distinct L region and R region within the device plane, where each region stores images for specific eyes. This segmentation enables independent processing and playback of left and right eye images, ensuring proper stereoscopic display while organizing the large-capacity storage into manageable, standardized segments.
2Adaptability or versatility
If multiple playback modes are defined for graphics, video, and background images, then adaptability to different 3D content types is improved, but system complexity increases
Solution Approach 1:
The patent implements universality by creating a multi-functional playback system that handles various content types (graphics images, video images, background images) through a unified device plane configuration. The same L/R region structure and playback modes (mono, stereo, offset, flattened stereo, forced mono) are applied across all content types, providing adaptability without proportionally increasing system complexity.
Solution Approach 2:
The patent applies local quality by allowing different playback modes to be assigned to different content types and regions. Each content type (graphics, video, background) can have its own mode configuration, enabling optimized playback for each specific content type while maintaining overall system manageability through localized rather than global complexity.
3Manufacturing precision
If storage regions for left and right eye images are collaterally arranged, then playback quality is improved, but data organization complexity increases
Solution Approach 1:
The patent segments the device plane into distinct L region and R region that are collaterally arranged, with each region dedicated to storing images for a specific eye. This segmentation improves playback precision by ensuring proper spatial organization of stereoscopic image pairs while managing data organization complexity through clear, standardized regional boundaries.
Solution Approach 2:
The patent transitions from traditional single-plane storage to a two-region collateral arrangement, adding a spatial dimension to the storage organization. By arranging L and R regions side-by-side rather than stacking them, the system achieves better playback quality through improved spatial correspondence while organizing data in a more intuitive two-dimensional layout.

AI summary
The present invention relates to an information processing device, an information processing method, and a program, whereby a graphics mode to play a graphics image, or the like can be changed without changing resolution. A device plane to store a graphics, video, or background image is a storage region where an L region to store an image for L, and a R region to store an image for R are collaterally arranged, and the configuration of the device plane is defined as to the whole of the device plane that is of storage regions for two images. The graphics mode or the like is included in the configuration of the device plane, and a configuration mode setting API sets the graphics mode. The present invention may be applied to a BD player configured to play a BD, or the like.
