3D Content Identification Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital receivers fail to distinguish and indicate 3D content among mixed 2D and 3D digital content, leading to viewer confusion and potential display issues like broken or flickering images when 3D content is viewed in 2D mode.
Innovation Solution
A signal processing apparatus and method that determines the 3D or 2D nature of content by extracting attribute information from signaling data or autonomously using Euclidean distance calculations, and displays 3D content identification information to differentiate it from 2D content in user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a receiver provides content information without distinguishing 3D content, then the content information is simple and easy to process, but the viewer cannot identify 3D content leading to display issues
Solution Approach 1:
The patent extracts 3D content identification information from the content signal by analyzing attribute information in the signal. The receiver separates the 3D identification task from general content processing, using dedicated analysis of signaling data to detect 3D attributes without complicating the overall content delivery system.
Solution Approach 2:
The patent introduces an intermediary 3D identification indicator that mediates between the content signal and the user interface. This indicator serves as a bridge, conveying 3D content information from the signal processing layer to the user interface layer without requiring complex integration across the entire system.
2Reliability
If the receiver autonomously determines 3D content without attribute information, then content identification is possible, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary analysis of signaling information to determine content attributes before full content processing. By checking for the presence of attribute information in advance, the receiver can decide whether to use simple attribute extraction or proceed to more complex autonomous determination methods.
Solution Approach 2:
The patent applies partial action by using Euclidean distance calculations only when necessary (when attribute information is absent). The system first attempts simpler attribute extraction methods, and only performs the more complex autonomous determination with Euclidean distance calculations when absolutely needed, thus minimizing overall processing complexity.

AI summary
A method and apparatus may be provided that includes receiving a signal that includes content at an image display device, determining whether the content within the received signal includes three dimensional (3D) image data, displaying information about the content within the received signal on a display of the image display device, and displaying a 3D indicator on the display when the content within the received signal is determined to include 3D image data.
