Solution Overview
Problem
Current stereoscopic video display technologies face challenges in adaptively processing graphic data to increase commercial value and accommodating various systems, particularly in ensuring stable depth information for dynamic images without affecting graphic data quality.
Innovation Solution
A stereoscopic video signal processing apparatus and method that defines a basic format for 3D signals with separate areas for main video data, graphic data, and depth information, allowing a 3D processing module to select between patterns that either insert or exclude graphic data into main video data, using a 3D related controller to decide the appropriate pattern based on video characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If graphic data is inserted into main video data, then commercial value and adaptability are improved, but processing complexity and delay time increase
Solution Approach 1:
The video signal is segmented into separate areas: main video data area, graphic data area, and depth information area. This segmentation allows independent processing of each component, reducing overall processing complexity while maintaining adaptability. The 3D processing module can selectively process only the necessary areas based on the chosen pattern.
Solution Approach 2:
The system dynamically selects between two processing patterns based on video characteristics. The 3D related controller decides whether to insert graphic data into main video data or keep them separate, allowing the processing complexity to adapt to the specific content requirements, thus optimizing the balance between adaptability and processing load.
2Adaptability or versatility
If graphic data is inserted into main video data, then commercial value is improved, but delay time in dynamic image processing increases
Solution Approach 1:
The processing pattern is dynamically adjusted based on video characteristics. For dynamic images where delay time is critical, the system selects the pattern that excludes graphic data insertion, thereby reducing processing delay. For static or less time-sensitive content, the system can insert graphic data to enhance commercial value without significantly impacting delay time.
3Reliability
If depth information is processed for graphic data, then stereoscopic video quality is improved, but processing complexity increases
Solution Approach 1:
Depth information is segmented into a separate dedicated area rather than being mixed with main video data and graphic data. This segmentation simplifies the processing pipeline by allowing independent depth information processing, reducing overall processing complexity while ensuring stable depth information for stereoscopic video quality.
Solution Approach 2:
The patent introduces an intermediary structure where depth information is processed separately and then integrated with the main video data. This intermediary approach allows for specialized depth processing algorithms to be applied without complicating the overall system, maintaining reliability while managing complexity.

AI summary
According to one embodiment, a basic format for a 3D signal having a first area to arrange main video data, a second area to arrange graphic data, a third area to arrange depth information of pixels of the main video data, and a fourth area to arrange depth information of pixels of the graphic data are defined. When depth information of pixels of the main video data is generated, a 3D processing module can select whether to use a first pattern obtained by inserting the graphic data into the main video data and a second pattern obtained by not inserting the graphic data into the main video data. A 3D related controller decides on the first or second pattern to be used by the 3D processing module.
