Video Reception Device Content Recognition Region Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video reception systems fail to accurately superimpose additional information on video signals due to difficulties in recognizing video content features, especially when superimposing information like captions or OSDs is present, leading to inefficiencies in content recognition and additional information display.
Innovation Solution
A video reception device that extracts partial videos, sets video recognition regions based on feature information, and generates fingerprints for content recognition, allowing it to request video recognition processing from a connected device and superimpose additional information on the video signals, thereby overcoming the challenges of superimposed content features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video recognition processing is performed on the entire video signal, then content recognition accuracy is improved, but processing time and computational load increase significantly
Solution Approach 1:
The patent divides the video signal into multiple frames and selectively extracts specific frames for recognition processing. Instead of processing the entire video sequence, the system identifies and processes only key frames that contain meaningful content, thereby reducing computational load and processing time while maintaining recognition accuracy.
Solution Approach 2:
The patent applies different processing strategies to different portions of the video signal. It identifies regions with superimposed information (captions, OSDs) and excludes these regions from recognition processing, while focusing computational resources on regions containing actual video content. This local differentiation optimizes both accuracy and efficiency.
2Adaptability or versatility
If video recognition processing is performed on video signals with superimposed information, then content recognition is attempted, but recognition accuracy deteriorates due to interference from captions and OSDs
Solution Approach 1:
The patent extracts and removes superimposed information (captions, OSDs, subtitles) from the video signal before performing recognition processing. By separating these interfering elements from the main video content, the system prevents them from degrading recognition accuracy while preserving the ability to recognize the actual video content.
Solution Approach 2:
The patent applies different processing treatments to different regions of the video signal. It identifies regions containing superimposed information and excludes them from recognition processing, while applying full recognition processing to regions containing pure video content. This regional differentiation maintains high recognition accuracy despite the presence of superimposed elements in the overall video signal.
3Loss of information
If additional information is superimposed on video signals with existing superimposed information, then information completeness is improved, but visibility and display quality deteriorate
Solution Approach 1:
The patent divides the video signal into multiple frames and selectively superimposes additional information only on frames that do not already contain superimposed content. By segmenting the video sequence and applying additional information selectively rather than continuously, the system maintains information completeness while avoiding visual clutter and preserving display quality on frames where additional information is added.

AI summary
Video recognition processing on video signals input from an outside is performed. Hence, video reception device which is configured to transmit and receive data through communication network includes input unit, video extraction unit, video recognition region setting unit, control unit and additional information display control unit. The video recognition region setting unit sets a video recognition region to a partial video based on feature information indicating features of video signals input from an outside. The additional information display control unit generates content recognition information in the video recognition region of the partial video. The control unit performs control of requesting video recognition device to perform video recognition processing on this content recognition information.
