Video Screen Logo Obstruction Overlay Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively and efficiently remove distracting extraneous image elements from TV broadcasts, such as crawls and logos, which can be annoying to viewers, and existing solutions are either complex or not cost-effective.
Innovation Solution
A simple and cost-effective method and system that allows viewers to selectively block or replace undesirable image elements on a TV screen with customizable blocks of various sizes and colors, using a remote control to activate a block overlay device that generates black blocks or matches the surrounding image colors to minimize visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If image processing algorithms are used to detect and remove video logos, then extraneous image elements can be eliminated, but the method is compute-intensive and complex
Solution Approach 1:
The patent extracts and removes specific extraneous image elements (logos, crawls, scoreboards) from the video stream by detecting their characteristic features such as color uniformity, motion patterns, and positional consistency. Once detected, these elements are selectively removed or replaced with background-inferred pixels, separating the unwanted elements from the main video content without requiring complex full-frame processing
Solution Approach 2:
Instead of using computationally expensive and complex image processing algorithms, the patent employs simpler, more efficient detection methods that use basic color analysis and motion detection. The solution uses lightweight processing that consumes less computational power, making it suitable for cost-effective implementation in consumer TV devices
2Object-affected harmful factors
If manual selection of logo regions is used, then logo detection can be achieved, but the process is time-consuming and not automated
Solution Approach 1:
The system automatically detects and removes extraneous image elements without requiring manual user input. The detection algorithm autonomously identifies logos and other unwanted elements by analyzing color patterns, motion characteristics, and positional information, then automatically performs the removal or replacement operation, making the entire process self-service and eliminating manual selection time
Solution Approach 2:
The patent performs preliminary detection and analysis of video frames to identify extraneous elements before the actual removal process. By pre-identifying the characteristics of unwanted elements (such as storing color histograms and motion patterns), the system prepares the necessary information in advance, enabling faster and more efficient removal without requiring manual intervention during playback
3Object-affected harmful factors
If image inpainting technique is used to restore regions after logo removal, then the picture areas can be filled in, but the method is compute-intensive
Solution Approach 1:
Instead of applying complex inpainting algorithms to the entire frame, the patent applies simple pixel copying and color matching only to the specific small regions where logos were removed. The system analyzes the local background surrounding the removed element and uses nearby pixels to fill the gap, requiring minimal computational energy while effectively restoring the local area

AI summary
A simple, cost-effective, and robust method and system to obstruct crawls, logos, and other annoying and distracting images overlaid on a video signal and displayed on a TV set or monitor is provided. The method and system may detect the presence of the unwanted images and block them automatically, or they may accept manual input from the user via a handheld control device to block or obstruct these images.
