3D Closed Captioning via Depth-Encoded Location Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed captioning techniques are unsuitable for three-dimensional displays due to difficulties in identifying a standard location for caption information, as imagery is processed in more than two dimensions and is highly configurable, making it challenging to preserve the 3D experience while displaying captions.
Innovation Solution
Incorporating location identification information into three-dimensional programming to specify the position of caption data within the 3D space, allowing for configurable and effective display of captions that account for user preferences and occlusion effects, thereby preserving the 3D experience.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional two-dimensional closed captioning techniques are used in three-dimensional displays, then the caption information can be displayed, but the standard location for caption information cannot be identified and the 3D experience is compromised
Solution Approach 1:
The patent extends conventional two-dimensional captioning to three-dimensional space by introducing depth as an additional dimension. Caption information is positioned using three-dimensional coordinates (x, y, z) where z represents depth relative to the display plane. This allows captions to be placed at various depths within the 3D scene, enabling them to appear in front of, behind, or integrated with three-dimensional objects, thus resolving the location identification problem in 3D displays.
Solution Approach 2:
The system dynamically adjusts caption placement based on the three-dimensional content being displayed. Caption locations are not fixed but are determined relative to the dynamic elements in the 3D scene, allowing captions to maintain appropriate positioning as the scene changes. This dynamic approach enables adaptability to different 3D content while maintaining ease of operation through automated positioning.
2Adaptability or versatility
If three-dimensional displays are made highly configurable to suit viewer environments and preferences, then viewer comfort is improved, but it becomes difficult to identify a standard location for closed caption data
Solution Approach 1:
The patent applies different quality attributes to different regions of the three-dimensional display space. Specific zones or regions within the 3D scene are designated as preferred locations for caption placement, with each region having optimized characteristics for caption visibility and readability. This local quality approach allows the display to maintain high configurability for different viewing preferences while providing standardized caption locations within those configured spaces.
Solution Approach 2:
The system performs preliminary determination of caption locations during the content preparation or initial display setup phase. Based on the configured three-dimensional display parameters and expected content types, standard caption locations are pre-established within the 3D space. This preliminary action simplifies subsequent caption placement operations, maintaining both configurability and standardization without increasing device complexity.

AI summary
Systems and methods are presented for processing three-dimensional (3D or 3-D) or pseudo-3D media content. The programming includes closed caption (CC) information that includes caption data and a location identifier that specifies a location for the caption data within the 3D programming. The programming information is processed to render the caption data at the specified location within the media content and to present the programming on the display. By encoding location identification information into the three-dimensional media content, a high level of configurability can be provided and the 3D experience can be preserved while captions are displayed.
