Scanable Icon Detection in Video Streams Without Optical Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for capturing QR codes and similar encoded information from video streams require an optical path and a display device, making it difficult for users, especially those with older television receivers or low motivation, to interact with scannable icons, particularly the elderly and techno-phobic.
Innovation Solution
A system that automatically detects and decodes scannable icons embedded in video streams without the need for an optical path, using a data stream processor, video decoder, graphical image detector, and lookup table to locate and replace or substitute icons within the video data stream, enabling autonomous operation and easy access to encoded information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an optical path and display device are used for capturing QR codes, then the system can detect encoded information, but the ease of operation deteriorates for users with older television receivers or low motivation
Solution Approach 1:
The system automatically detects and decodes scannable icons embedded in video streams without requiring user action. The graphical image detector continuously monitors the video stream, locates icons, and extracts encoded information autonomously, eliminating the need for users to manually point cameras or interact with display devices.
Solution Approach 2:
The patent replaces the optical path mechanism (camera, display device, optical scanner) with a digital signal processing system. The graphical image detector processes video data streams digitally to locate and decode icons, substituting the mechanical/optical capture process with electronic detection and processing.
2Reliability
If an optical path is required for barcode scanning, then the system can recover encoded information, but the device complexity increases due to requirements for display devices and optical components
Solution Approach 1:
The patent extracts the scannable icon detection function from the optical path system. Instead of requiring cameras and display devices, the system extracts encoded information directly from the video stream data itself, eliminating optical components while maintaining information recovery capability.
Solution Approach 2:
The system replaces mechanical/optical scanning components with digital signal processing. The graphical image detector uses software algorithms to locate and decode icons within video frames, substituting physical optical scanners with electronic data processing capabilities.
3Reliability
If manual intervention is required for capturing icons, then the system can decode encoded information, but the productivity decreases due to user motivation limitations
Solution Approach 1:
The graphical image detector operates continuously throughout the video stream, constantly monitoring for scannable icons. This continuous detection ensures that icons are captured immediately upon appearance, eliminating interruptions caused by user motivation or manual intervention, thereby maximizing capture rate and productivity.
Solution Approach 2:
The system performs autonomous detection and decoding without requiring user participation. The graphical image detector independently identifies and extracts encoded information from the video stream, maintaining continuous operational productivity regardless of user presence or motivation levels.

AI summary
This invention enables Scanable Icons, which may be predetermined graphical images, and similar encoded information to be applied to video systems in a manner that is user-friendly and brings many of the advantages of easy information access and management to the video environment. The optical path normally required when using such encoded information is avoided. Supplementary information, including more details for advertisements, is provided in a non-invasive manner, allowing the user to access the supplementary information at convenient times and locations. The Scanable Icon adds a symbol to the existing advertisement without increasing its duration. Advertising is made substantially more effective for the advertiser and more useful for the consumer.
