Solution Overview

Problem

Current technologies lack effective methods for controlling the operation of external apparatuses in synchronization with AV content during digital television broadcasts, particularly in integrating Internet-based services with digital television broadcasts.

Innovation Solution

A reception apparatus and terminal apparatus system that receives AV content, executes application programs based on commands, and transmits control commands to each other to manage the operation of both apparatuses in an interlocked manner, utilizing trigger information embedded in the AV content to control the execution and termination of applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If application programs are supplied to control the operation of external apparatus in interlocked relation to AV content, then the functionality and integration of Internet-based services with digital television broadcasts is enhanced, but the device complexity and difficulty of controlling multiple apparatuses increases

Engineering Contradiction:

Improveintegration of Internet-based services with digital television broadcastsVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reception apparatus serves as an intermediary device that receives AV content, extracts trigger information, and transmits control commands to external terminal apparatus. This mediator approach allows the system to integrate Internet-based services with digital television broadcasts without requiring complex direct control mechanisms between all components, thereby enhancing functionality while managing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple application programs are executed across reception apparatus and terminal apparatus, then the operational versatility is improved, but the ease of operation and synchronization management deteriorates

Engineering Contradiction:

Improveoperational versatilityVSAvoidsynchronization management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements feedback mechanisms where the reception apparatus transmits control commands to external terminal apparatus based on trigger information extracted from AV content. The terminal apparatus executes application programs and feeds back operational status, enabling automatic synchronization of multiple applications across devices without requiring manual coordination, thus maintaining ease of operation while achieving operational versatility.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The reception apparatus performs preliminary actions by extracting trigger information from AV content and preparing control commands before transmitting them to external terminal apparatus. This preliminary processing ensures that application programs are executed in the correct sequence and timing, facilitating automatic synchronization across multiple devices without requiring complex real-time coordination during operation.

Inventive Principle:

Principle #10Preliminary action

3Extent of automation

If trigger information is extracted from AV content to control application execution, then the automation level is improved, but the measurement precision and reliability of command execution increases requirements

Engineering Contradiction:

Improveautomatic control of application executionVSAvoidtrigger information extraction accuracy

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The system replaces manual control mechanisms with automated information processing by extracting trigger information directly from AV content. This substitution of mechanical/manual operations with automated digital signal processing enables high-level automation of application execution control while maintaining precision through systematic digital extraction and command transmission protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
