Solution Overview

Problem

Digital TV systems face challenges in accurately executing user-intended functions upon receiving voice commands due to inefficiencies in determining the provider of the desired service, leading to suboptimal service delivery and security concerns related to data transmission.

Innovation Solution

A display device equipped with a determination module that identifies the provider of the voice command function, allowing for localized processing and reducing the need for external server communication, thereby enhancing execution speed, accuracy, and security by minimizing data transmission and traffic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the display device transmits voice command data to external servers for processing, then the accuracy of function execution is improved, but the data transmission time increases and security is compromised

Engineering Contradiction:
Improveaccuracy of function executionVSAvoiddata transmission time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system segments the voice command processing function by separating the determination module that identifies the service provider from the external servers. This local segmentation allows the display device to independently determine which external server should handle the voice command, eliminating the need to transmit the entire voice command data to multiple servers for determination, thus reducing transmission time while maintaining accurate function execution.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the display device transmits voice command data to external servers, then the accuracy of function execution is improved, but the security is worsened due to increased data transmission

Engineering Contradiction:
Improveaccuracy of function executionVSAvoidsecurity
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system segments the processing architecture by keeping the determination module locally within the display device while only transmitting minimal identification data to external servers. This segmentation reduces the volume of sensitive voice command data transmitted over the network, thereby improving security while still enabling accurate function execution through targeted communication with the identified service provider.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the determination module is provided within the display device, then the data transmission is reduced and security is improved, but the device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts only the essential determination function from the external servers and implements it as a dedicated determination module within the display device. This extraction approach adds a specific functional component to the device, but the module is designed to be integrated into the existing control unit, minimizing overall device complexity while achieving the security benefits of localized processing.

Inventive Principle:
Principle #2Taking out (Extraction)

4Measurement precision

If multiple external servers are queried for voice command processing, then the accuracy of service identification is improved, but the traffic and processing time increase

Engineering Contradiction:
Improveaccuracy of service identificationVSAvoidprocessing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary action by pre-establishing registration information between external servers and the display device before voice command processing occurs. The determination module uses this pre-configured information to directly identify the appropriate service provider without needing to query multiple servers, thereby maintaining accurate service identification while significantly improving processing speed and reducing network traffic.

Inventive Principle:
Principle #10Preliminary action
