Game Moving Image Recording and Event-Based Scene Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in efficiently finding specific game moving images that correspond to their play scenes, especially when the reproduction time period is long, and there is a need to prevent spoilers by identifying relevant play situations within the game moving images.
Innovation Solution
An information processing system that automatically records game moving images and extracts specific segments based on user-defined start and end points, correlating this with event information to enable precise searching and spoiler prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the reproduction time period of game moving images is extended to cover more play scenes, then the comprehensiveness of game content increases, but the time required for users to locate specific desired scenes increases
Solution Approach 1:
The patent segments the continuous game moving image into multiple sections with distinct metadata tags representing different play scenes (e.g., battle scenes, exploration scenes, cutscenes). Each section is independently identifiable through its metadata, allowing users to quickly locate specific scenes without watching the entire moving image. This segmentation directly resolves the contradiction by maintaining comprehensive content while enabling rapid scene location.
Solution Approach 2:
The patent performs preliminary action by automatically generating and attaching metadata to each section of the game moving image during the indexing process. This pre-processing creates a searchable structure that allows users to immediately find desired scenes without manual searching, thus reducing location time while preserving comprehensive content coverage.
2Quantity of substance
If comprehensive game moving images are provided without scene specification, then all play scenes are covered, but users cannot easily identify or jump to their desired play situations
Solution Approach 1:
The patent divides the game moving image into multiple sections, each associated with specific metadata that describes the play scene (e.g., character actions, event types, location). This segmentation enables users to easily identify and navigate to desired scenes by searching or filtering based on metadata, directly improving ease of operation while maintaining comprehensive scene coverage.
Solution Approach 2:
The patent implements a feedback mechanism where metadata about play scenes is provided back to users in the form of searchable tags and scene descriptions. This feedback allows users to verify whether a moving image contains their desired play situation and to directly jump to relevant sections, significantly improving ease of locating desired scenes.
3Measurement precision
If event information is added to game moving images to enable precise searching, then search accuracy improves, but the complexity of data processing increases
Solution Approach 1:
The patent extracts essential event information from the game moving image and separates it into distinct metadata elements. By taking out only the critical event data (such as character actions, battle events, and scene transitions) and storing it as structured metadata, the system achieves high search accuracy without requiring complex processing of the entire moving image data, thus resolving the contradiction between search precision and data processing complexity.

AI summary
A first ring buffer 142 records a game moving image by game software 110 currently being executed, together with time information. In a case where an event is generated in a game, an event information acquiring part 120 acquires event information including an event code that identifies the generated event, from the game software 110. A second ring buffer 144 records therein the acquired event information together with the time information synchronized with the first ring buffer 142.
