Solution Overview

Problem

Existing digital television broadcasting systems lack the ability to transmit control information according to an operation form, and there is a need to manage control information independently for each service provider and transmit it accordingly.

Innovation Solution

A transmission device generates first data including control information and transmission sequence information, which is transmitted in a specific sequence, and a reception device processes this data to control the handling of service components based on the transmission sequence information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If control information is transmitted without sequence management, then transmission simplicity is maintained, but the ability to transmit control information according to operation form is lost

Engineering Contradiction:

Improveability to transmit control information according to operation formVSAvoidcomplexity of transmission sequence management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control information is segmented into multiple pieces, each assigned a transmission sequence number. This allows the reception device to reconstruct control information in the correct order even when received out of sequence, enabling flexible transmission according to operation form while maintaining manageable complexity through structured segmentation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Transmission sequence numbers are preliminarily assigned to control information pieces before transmission. This preliminary ordering enables the reception device to automatically reassemble control information in the correct sequence without complex real-time processing, achieving adaptability while controlling device complexity

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If control information is managed independently for each service provider, then service provider independence is achieved, but transmission management complexity increases

Engineering Contradiction:

Improveindependent management of control information for each service providerVSAvoidcomplexity of multi-provider control information management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Control information is segmented and organized by service provider identifiers. Each service provider's control information pieces are independently numbered and managed, allowing the reception device to separately process and reassemble control information from multiple providers without cross-interference, achieving independence while managing complexity through structured organization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Transmission sequence numbers act as an intermediary mechanism that standardizes the management of control information from multiple service providers. By using a common numbering scheme that incorporates provider identification, the system enables independent provider management while maintaining unified transmission coordination

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If all control information is transmitted immediately, then information availability is maximized, but transmission bandwidth is wasted

Engineering Contradiction:

Improveavailability of control informationVSAvoidtransmission bandwidth consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The transmission timing of control information pieces is made dynamic based on operational needs. The system can transmit control information pieces at different times according to their urgency and the operation form, rather than transmitting all information immediately. This dynamic approach ensures necessary information is available when needed while minimizing unnecessary bandwidth consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The transmission parameters of control information are changed based on operation form requirements. By adjusting transmission timing, sequence, and prioritization according to operational needs, the system maximizes information availability for critical operations while reducing bandwidth consumption by transmitting only necessary information at appropriate times

Inventive Principle:

Principle #35Parameter changes
