Solution Overview

Problem

Existing application control methods, such as AIT, require temporal continuity and are complex to manage, making it difficult to easily control the operation of applications accompanying content.

Innovation Solution

A reception device and data processing method that utilize valid period information to control the activation of applications, allowing for easy management and operation of applications by receiving and processing content with associated valid period information, and a transmission device that generates and transmits this information alongside the content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If application control information (AIT) is used to control the lifecycle of the application according to sending timing, then the application operation can be controlled, but temporal continuity is required and the control becomes complicated

Engineering Contradiction:

Improveease of controlling application operationVSAvoidcomplexity of control

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the essential control element (valid period information) from the complex AIT system. Instead of using comprehensive application control information with multiple parameters and temporal continuity requirements, the invention isolates and transmits only the critical valid period data, thereby simplifying the control mechanism while maintaining effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a lightweight, self-contained valid period information structure that is transmitted with each content delivery. This disposable control mechanism does not require maintaining complex state information or ensuring temporal continuity across multiple transmissions, unlike the AIT system

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If AIT controls the lifecycle of the application according to sending timing, then the application can be controlled, but temporal continuity is required

Engineering Contradiction:

Improvereliability of application controlVSAvoidtemporal continuity requirement

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent incorporates the valid period information in advance with the content or application data. This preliminary inclusion ensures that the reception device has all necessary control information immediately available, eliminating the need for continuous temporal validation or repeated requests for control information that would be required by AIT

Inventive Principle:

AI summary

The present technology relates to a reception device, a transmission device, and a data processing method for easily controlling operation of an application accompanying content.The reception device receives the content and controls activation of the application accompanying the content on the basis of valid period information indicating a period in which the application is valid, thereby to easily control the operation of the application accompanying the content. The present technology can be applied to, for example, a television receiver or the like capable of receiving terrestrial broadcasting.
