Solution Overview

Problem

Existing systems for providing moving images during events, such as sports events, do not always match the viewer's preferences, leading to suboptimal viewing experiences.

Innovation Solution

A network management device that ranks multiple moving images captured by wireless communication terminals, increases uplink throughput for higher-ranked images, and generates an overall video signal for simultaneous reproduction, ensuring higher frame rates and high-definition playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automatically selected moving images are provided based on predetermined switching conditions, then the system can provide moving images without manual selection, but the moving images may not match viewer preferences

Engineering Contradiction:

Improveautomatic moving image selectionVSAvoidviewer preference matching

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system implements feedback by collecting viewer preferences and using them to dynamically adjust and rank moving image selections. The network management device ranks multiple moving images based on stored viewer preference information, ensuring that automatically provided images align with individual viewer preferences rather than using fixed predetermined conditions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transitions from static predetermined switching conditions to dynamic preference-based ranking. The network management device continuously ranks moving images based on updated viewer preference information, allowing the system to adaptively provide moving images that match evolving viewer preferences while maintaining automation

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If multiple high-definition moving images are provided simultaneously, then viewer experience is enhanced, but uplink throughput requirements increase

Engineering Contradiction:

Improvemoving image qualityVSAvoiduplink throughput

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system changes parameters by dynamically adjusting uplink throughput allocation based on moving image rankings. The network management device increases uplink throughput specifically for wireless communication terminals providing highly ranked moving images, allowing high-definition quality for selected images while managing overall throughput requirements through selective resource allocation

Inventive Principle:

Principle #35Parameter changes

3Speed

If uplink throughput is increased for wireless communication terminals providing highly ranked moving images, then frame rate and definition are improved, but network resource consumption increases

Engineering Contradiction:

Improveframe rateVSAvoidnetwork resource consumption

Core Design Contradiction:

SpeedVSLoss of energy

Solution Approach 1:

The system applies local quality by providing differentiated throughput allocation to specific wireless communication terminals based on their moving image rankings. Rather than uniformly increasing throughput for all terminals, the network management device selectively increases uplink throughput only for terminals providing highly ranked moving images, optimizing frame rate and definition where needed while conserving network resources elsewhere

Inventive Principle:

Principle #3Local quality

AI summary

A network management device includes a processor configured to execute a ranking process, a throughput-increasing process, an overall video signal generation process, and an overall video signal supplying process. In the ranking process, the processor ranks multiple moving images taken by cameras of wireless communication terminals simultaneously capturing an event performed in an event venue to select multiple moving images ranked higher. In the throughput-increasing process, the processor increases uplink throughput for the multiple wireless communication terminals corresponding to the multiple moving images ranked higher selected in the ranking process. In the overall video signal generation process, the processor generates an overall video signal including multiple video signals corresponding to the multiple wireless communication terminals for which the uplink throughput is increased in the throughput-increasing process. In the overall video signal supplying process, the processor supplies the overall video signal generated in the overall video signal generation process to at least one reproduction device in which moving images are reproduced. The overall video signal is in a format that enables the reproduction device to simultaneously reproduce the multiple moving images corresponding to the multiple video signals in the overall video signal.
