Hardware Feedback Loop for Display Content Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for verifying content presentation on distributed electronic signage are challenging due to their location-specific nature, making it difficult to implement conventional verification and auditing methods, which rely on third-party data and software-level processes, and thus cannot ensure that content is presented on a hardware level.
Innovation Solution
A hardware feedback loop is implemented at the display, using a DCIC circuit to create checksums and timestamps for each frame of content, ensuring double authentication verification and logging of media presentation, thereby providing a hardware-level auditing process that ensures content is presented on asynchronous displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional verification methods are used, then third-party data and software-level processes can provide audience measurement, but hardware-level verification of content presentation cannot be ensured
Solution Approach 1:
The patent implements a feedback loop where the display device sends acknowledgment signals back to the content delivery system. This feedback mechanism confirms whether content was successfully received and presented on the display, enabling hardware-level verification without requiring complex external auditing infrastructure.
Solution Approach 2:
The patent introduces an intermediary verification layer between the content delivery system and the display device. This intermediary component facilitates communication and verification without requiring direct involvement of third-party auditing companies, simplifying the overall system architecture while improving verification reliability.
2Adaptability or versatility
If distributed signage is used, then content can be presented at multiple locations, but verification of content presentation becomes difficult or impossible
Solution Approach 1:
The patent enables distributed signage systems to perform self-verification. Each display device autonomously monitors its own content presentation and generates verification data, eliminating the need for external verification services. This self-service approach maintains distribution versatility while solving the verification difficulty across multiple locations.
Solution Approach 2:
The patent divides the verification process into independent segments at each display location. Each display device operates as an independent verification unit, generating and transmitting its own verification data. This segmentation allows scalable verification across distributed locations without creating a centralized verification bottleneck.
3Loss of information
If software-level auditing is used, then content presentation can be tracked, but hardware-level assurance cannot be provided
Solution Approach 1:
The patent replaces software-level auditing mechanisms with hardware-level verification. By implementing verification logic directly in the display device hardware, the system achieves more accurate content presentation tracking while avoiding the complexity of sophisticated software auditing solutions. The hardware-level approach provides direct assurance that content was actually presented on the display.
