Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In the context of program production, especially in broadcast stations, retrieving desired video materials from a large quantity of photographed materials is time-consuming due to the need for manual memo input to associate video materials, increasing the workload and retrieval time.

Innovation Solution

An associating device that automatically associates memos with video materials using input start time information and photography time information, allowing for keyword-based retrieval without the need for explicit identification of video materials during memo input, and utilizing group-to-group relationship determination based on correction history and position information to enhance accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If memo input personnel explicitly add video material identification information when inputting memo information, then the memo can be accurately associated with the video material, but the workload and time required for memo input increases significantly

Engineering Contradiction:

Improveassociation accuracyVSAvoidmemo input efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system automatically performs the association between memo information and video material identification information without requiring manual intervention. The associating device extracts identification information from the video material itself and automatically links it with the memo input, making the system self-servicing rather than relying on human operators to perform the matching task

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The video material identification information is extracted and prepared in advance before the memo input process. By pre-processing the identification information and making it available beforehand, the system eliminates the need for manual matching during memo input, thereby improving efficiency while maintaining accuracy

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual retrieval methods are used by viewing video materials to find desired content, then comprehensive search is possible, but the retrieval time increases significantly

Engineering Contradiction:

Improveretrieval completenessVSAvoidmaterial retrieval time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces memo information as an intermediary element that mediates between the searcher and the video material. Instead of directly searching through video content, users search through memo information which has been automatically associated with video materials, significantly reducing retrieval time while maintaining search effectiveness

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/manual process of viewing video materials to find desired content with an automated information processing system. The associating device automatically extracts, processes, and indexes video material information, substituting manual mechanical search with automated computational processes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An object of the invention is to make it possible to input memo information for each video material without being conscious of the association with the video material. The associating device according to the invention includes an association determination section 40 for associating a word with a video material by using the input start time information on an inputted word and the photography time information on a photographed video material.
