Solution Overview

Problem

Current multimedia content output systems face challenges in efficiently utilizing multiple output devices, leading to quality losses and neglecting individual user interests, particularly when multiple users with different preferences access the same content simultaneously, and require high user control efforts.

Innovation Solution

A method for selective multimedia content output that determines an output criterion based on the first and second multimedia content, allowing for the formation of a third multimedia content suitable for terminal devices, enabling automatic adaptation and optimal use of available output units without user intervention, thereby enhancing ease of use and quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple output devices are used to deliver multimedia content to multiple users simultaneously, then individual user preferences can be accommodated, but quality losses occur and device complexity increases

Engineering Contradiction:

Improveaccommodation of individual user preferencesVSAvoidcontent quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system segments the multimedia content into multiple separate streams, with each stream optimized for a specific output device and user preference. The content processing unit divides the incoming content into first multimedia content for the first output unit and second multimedia content for the terminal device, allowing each to be delivered at optimal quality without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies local quality by delivering different quality levels and formats to different output devices based on their specific capabilities and user preferences. The first output unit receives content optimized for its specific characteristics, while the terminal device receives content adapted to its display capabilities, ensuring each receives the appropriate quality level for its context.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple output devices are used to deliver multimedia content to multiple users simultaneously, then individual user preferences can be accommodated, but device complexity and user control efforts increase

Engineering Contradiction:

Improveaccommodation of individual user preferencesVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically detecting user requests and autonomously determining output criteria without requiring manual user control. The content processing unit automatically monitors requests from terminal devices, determines appropriate output criteria based on device capabilities and user preferences, and delivers customized content streams without user intervention, reducing both device complexity and control efforts.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms where terminal devices send requests to the content processing unit, which then monitors these requests and adjusts content delivery accordingly. The system continuously monitors output criteria and adapts content streams based on detected user preferences and device capabilities, creating a closed-loop system that reduces complexity through automated adaptation.

Inventive Principle:

Principle #23Feedback

3Manufacturing precision

If manual user control is used to select content format for each device, then content quality can be optimized, but user control efforts increase

Engineering Contradiction:

Improvecontent format optimizationVSAvoiduser control efforts

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs self-service by automatically determining output criteria and optimizing content formats for each device without requiring manual user control. The content processing unit autonomously analyzes device capabilities, monitors user requests, and selects appropriate content formats and quality levels, eliminating the need for users to manually configure settings while maintaining optimal content quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback loops where user requests and device capabilities are continuously monitored, and output criteria are automatically adjusted based on this information. The content processing unit receives feedback from terminal devices about user preferences and device characteristics, then automatically optimizes content format and delivery parameters, achieving high-quality content delivery without user intervention.

Inventive Principle:

Principle #23Feedback
