Solution Overview

Problem

Existing video reception systems lack the capability to effectively obtain and superimpose additional information related to video signals in real-time, especially during content switching or changes in screen layout, which can lead to visibility issues with overlayed information.

Innovation Solution

A video reception device that performs video recognition processing using a connected video recognition device to identify content and obtain additional information, such as advertisements, and dynamically controls the display of this information based on screen layout changes, using template matching and similarity calculations to ensure proper placement and visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If additional information is superimposed on video signals, then information provision is enhanced, but visibility of the additional information may be compromised during screen layout changes

Engineering Contradiction:

Improvevisibility of additional informationVSAvoidscreen layout flexibility

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic detection of screen layout changes by continuously monitoring video signals for template matching. When a layout change is detected, the system dynamically adjusts or stops superimposition of additional information, ensuring visibility is maintained adaptively across different screen configurations without compromising layout flexibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by detecting screen layout changes through video signal analysis and using this information to control the superimposition process. The detection result feeds back to the superimposition control, enabling the system to adjust information display based on actual screen conditions, thereby resolving the contradiction between information provision and visibility

Inventive Principle:

Principle #23Feedback

2Loss of information

If video recognition processing is performed to identify content, then additional information can be obtained, but processing time and system complexity increase

Engineering Contradiction:

Improveacquisition of additional informationVSAvoidprocessing time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent performs video recognition processing continuously or periodically to pre-identify content and obtain additional information before it is needed for superimposition. This preliminary action allows the system to have additional information ready in advance, reducing real-time processing delays while maintaining accurate content identification

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous video recognition and content identification processes, ensuring that additional information is always available when needed. This continuous operation eliminates gaps in information provision and reduces overall processing time by avoiding intermittent start-stop cycles, thereby balancing information acquisition with time efficiency

Inventive Principle:

Principle #20Continuity of useful action

3Loss of information

If additional information is superimposed on video signals, then user information access is improved, but the video content visibility may be reduced

Engineering Contradiction:

Improveaccess to additional informationVSAvoidvideo content visibility

Core Design Contradiction:

Loss of informationVSIllumination intensity

Solution Approach 1:

The patent applies additional information superimposition selectively in specific regions of the video screen, avoiding areas where it would interfere with primary video content visibility. By controlling the location and placement of additional information based on detected screen layouts, the system maintains both information accessibility and video content prominence, resolving the contradiction between information access and content visibility

Inventive Principle:

Principle #3Local quality

AI summary

Additional information related to video signals input from an outside is obtained and superimposed on the video signals. Hence, video reception device (40) which is configured to transmit and receive data through communication network (16) includes input unit (65), video extraction unit (45), control unit (41) and additional information display control unit (46). The control unit performs control of requesting video recognition device (20) to perform video recognition processing on a partial video extracted by the video extraction unit, and obtaining additional information based on a result of the video recognition processing from the video recognition device. The additional information display control unit performs control of detecting whether or not a screen layout of video signals has been changed, and superimposing the additional information on the video signals based on a detection result.
