Solution Overview

Problem

Current broadcast systems fail to effectively collect and process user information for personalized content delivery in non-real-time (NRT) services, leading to suboptimal content selection and decreased user convenience.

Innovation Solution

A personalization broadcast system that collects and processes user information through a digital broadcast system, utilizing techniques like automatic content recognition (ACR) and digital watermarking to provide personalized content optimized for user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If user information is collected for personalization service, then content selection accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvecontent selection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The user information processing system is segmented into distinct functional modules: a user information collection unit that gathers data from multiple sources, a user information processing unit that analyzes and categorizes the collected data, and a content selection unit that applies processing results to select personalized content. This modular segmentation reduces overall system complexity by allowing each component to be developed, tested, and maintained independently while improving content selection accuracy through comprehensive user information analysis.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If comprehensive user information is processed, then personalization service quality is improved, but processing time increases

Engineering Contradiction:
Improvepersonalization service qualityVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary processing of user information by pre-categorizing and structuring collected data into meaningful user profiles before content selection is needed. User preferences, viewing habits, and demographic information are processed and stored in an organized manner in advance, enabling the content selection unit to quickly retrieve and apply relevant user characteristics without performing complex analysis at the moment of content selection, thus reducing processing time while maintaining high personalization quality.
