Solution Overview

Problem

Current technologies lack the capability to provide an application program executed in linkage with AV content using Automatic Content Recognition (ACR) technology, hindering the realization of hybrid broadcasting and communication services.

Innovation Solution

A reception device equipped with a reception unit, feature value extraction unit, identification result acquisition unit, command acquisition unit, control unit, and detection unit, which extracts feature values from AV content, identifies the content using ACR, and controls application programs based on the identification results, ensuring seamless operation and closure when content switching occurs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ACR technology is used to identify AV content and provide linked application programs, then hybrid broadcasting and communication services can be realized, but no established technology exists for providing such application programs

Engineering Contradiction:

Improvehybrid service capabilityVSAvoidtechnology maturity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an ACR server as an intermediary component that mediates between the AV content delivery system and the application program distribution system. The server receives feature values from the reception device, performs content identification, and returns identification results that enable targeted application program provision, thus bridging the gap between broadcasting and communication infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is divided into distinct functional modules: a reception device for receiving AV content and extracting feature values, an ACR server for performing content identification using stored feature values, and a command execution unit for providing and executing application programs. This segmentation allows each component to be optimized independently while working together to achieve hybrid service functionality

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If application programs are executed in linkage with AV content, then user experience is enhanced, but system complexity increases due to need for feature extraction, content identification, and program management

Engineering Contradiction:

Improveuser experienceVSAvoidsystem structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The reception device automatically performs feature value extraction from AV content and transmits these feature values to the ACR server for identification. The system autonomously matches content with corresponding application programs without requiring manual user configuration, reducing operational complexity despite enhanced functionality

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The ACR server performs multiple functions: storing feature values of various AV contents, receiving and processing feature values from different reception devices, performing content identification, and providing commands for application program execution. This multi-functionality consolidates complex operations into a single universal platform

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If channel switching is detected to close running application programs, then resource management is improved, but detection accuracy must be high to avoid premature closure

Engineering Contradiction:

Improveresource management efficiencyVSAvoidchannel switching detection accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system continuously monitors AV content playback state and provides feedback to the control unit. When channel switching is detected through changes in content identification results or playback status, the system responds by closing associated application programs. This feedback mechanism ensures accurate detection and appropriate resource management

Inventive Principle:

Principle #23Feedback

AI summary

A reception device including a reception unit configured to receive AV content, a feature value extraction unit configured to extract a feature value from data of the received AV content, an identification result acquisition unit configured to acquire an identification result of the AV content identified using the extracted feature value, a command acquisition unit configured to acquire a command for controlling an operation of an application program that is executed in linkage with the AV content according to the acquired identification result, a control unit configured to control the operation of the application program according to the acquired command, and a detection unit configured to detect switching of the AV content being viewed. When the switching of the AV content is detected, the control unit closes the application program that has been executed in linkage with the AV content.
