Solution Overview

Problem

Existing methods for evaluating video data quality, particularly in cases of unsynchronized sound and picture, suffer from low accuracy due to subjective scoring methods that are influenced by personal prejudice and experience, leading to inconsistent and non-generalizable results.

Innovation Solution

A method utilizing electroencephalogram (EEG) data, including emotion and emotional response data, processed through transfer learning algorithms to determine a quality evaluation grade for video data with degraded quality, overcoming personal biases by introducing objective EEG-based evaluation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If subjective scoring methods are used to evaluate video quality, then the evaluation process is simple and fast, but the accuracy and reliability of the evaluation results deteriorate due to personal subjectivity and prejudice

Engineering Contradiction:
Improveevaluation speedVSAvoidevaluation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical system of subjective human scoring with an objective EEG-based measurement system. By using electroencephalogram data to detect and quantify user emotional responses to video quality degradation, the system eliminates personal subjectivity and prejudice while maintaining evaluation efficiency. The EEG signals provide physiological evidence of user experience, transforming the evaluation from a subjective mechanical process to an objective physiological measurement process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If EEG data with both emotion and emotional response information is collected and processed through transfer learning, then the evaluation accuracy is improved, but the system complexity and data processing requirements increase

Engineering Contradiction:
Improveevaluation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies transfer learning to pre-process and align the EEG data from different sources (emotion data and emotional response data) before final evaluation. This preliminary action of data alignment and feature extraction through transfer learning reduces the complexity of subsequent processing by establishing a unified data framework, making the system more manageable despite handling multiple data types.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces transfer learning as an intermediary processing layer between raw EEG data collection and final quality evaluation. This intermediary component bridges the gap between different EEG data types (emotion and emotional response), enabling effective integration and analysis while managing system complexity through a structured intermediate processing stage.

Inventive Principle:
Principle #24Intermediary (Mediator)
