Dynamic Mark Encoding for Reliable Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for converging digital media from TV or video screens with wireless smart devices are unreliable due to limitations such as distance, ambient light, and noise interference, making it frustrating for users to capture and decode information effectively.
Innovation Solution
The implementation of a Dynamic Mark (DM) system that uses a sequence of active image patterns with non-square shapes and multiple colors, encoded with a code book portion for dynamic calibration, allowing for efficient decoding regardless of display screen or environment, and enabling reward points for viewers who capture and decode these marks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical based systems are used to capture information from video displays, then information can be transmitted wirelessly to smart devices, but the system becomes unreliable due to short distance requirements, ambient light interference, and video display output variations
Solution Approach 1:
The patent uses color-coded pattern regions in the dynamic mark that change or vary in color intensity to encode information. The receiver detects these color variations to decode the transmitted data, making the system resistant to ambient light interference since the color information is actively modulated rather than passively reflected.
Solution Approach 2:
The patent employs a dynamic mark that changes its pattern over time rather than being static. The sequence of image patterns is displayed for a predetermined time period, allowing the receiver to capture and decode the information dynamically, which improves reliability by accommodating variations in capture timing and display output.
2Measurement precision
If conventional code structures like QR codes are used, then information can be encoded and decoded, but the system requires precise alignment and grid-like patterns that reduce flexibility in display integration
Solution Approach 1:
The patent uses asymmetric, non-square pattern regions arranged in a non-grid like pattern within the dynamic mark. This asymmetric design eliminates the need for precise alignment and grid structures required by conventional codes like QR codes, allowing flexible integration into video displays while maintaining decoding accuracy through the unique spatial arrangement of the pattern regions.
3Adaptability or versatility
If the dynamic mark uses non-square pattern regions in non-grid like arrangements, then adaptability to different display formats is improved, but the complexity of decoding the mark increases
Solution Approach 1:
The patent includes a code book portion in the dynamic mark that provides pre-defined reference information for decoding. The code book contains information about the expected pattern region arrangements and color codes, allowing the receiver to decode the dynamic mark without requiring complex real-time analysis of every possible pattern configuration, thus reducing decoding complexity while maintaining adaptability.

AI summary
Systems (100) and methods (2000) for providing a rewards program. The method involves presenting a Digital Dynamic Mark (“DDM”) to a viewer that comprises a sequence of Active Image Patterns (“AIPs”). Each AIP exclusively comprises First Pattern Regions (“FPRs”) for encoding symbols. At least two FPRs are rendered with at least one color other than a defined background color for the image pattern. The FPRs are arranged in a non-grid like pattern. Each FPR has a non-square shape with a single side boundary line directly abutting a single side boundary line of at least one other FPR. Information is received which indicates that the viewer captured an image of the DDM using a computing device thereof. Reward points are awarded to the viewer for capturing the image of the DDM. The reward points are redeemable by the viewer for one or more redemption items.
