Game Replay Video Generation via Log Data Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for sharing recorded game videos are cumbersome due to the large volume of data required for video uploads, which can be time-consuming and troublesome for users, especially if the upload process fails and needs to be repeated.
Innovation Solution
An information processing system that records game progress as log data, which is then used to recreate game screens as a replay video on a server, reducing the data volume and allowing for efficient transmission and sharing, while also enabling users to view replay videos without the need for dedicated software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user uploads recorded video data to a server for sharing, then other users can access and view the video, but the upload time becomes long and troublesome due to large data volume
Solution Approach 1:
The system performs preliminary recording of game progress data during gameplay, storing it in a manageable format. This preliminary action allows the actual video reconstruction to happen quickly on the server side without requiring lengthy uploads from the user's device.
Solution Approach 2:
The patent introduces an intermediary approach where instead of uploading complete video files, the system uploads structured game progress data (log data) that serves as a blueprint. The server then acts as a mediator that reconstructs the video from this data, significantly reducing upload time and data volume.
2Loss of information
If the user records video simultaneously while playing the game, then the video content is captured, but the user burden increases due to the complexity of recording and uploading large video files
Solution Approach 1:
The patent extracts only the essential game progress data needed to recreate video content, separating this from the actual video recording process. This extraction allows the system to capture game content in a compact, structured format that is much easier to handle and transmit than complete video files.
Solution Approach 2:
Instead of copying and uploading the actual video footage, the system creates a simplified copy in the form of structured log data that contains all necessary information to reconstruct the video. This copying approach maintains information integrity while dramatically reducing data size and operational complexity.
3Adaptability or versatility
If the video data is transmitted to the server, then video sharing is enabled, but the data volume is large requiring long transmission time
Solution Approach 1:
The system performs preliminary structuring of game data during gameplay, organizing it into a compact format that minimizes the quantity of data that needs to be transmitted. This preliminary organization enables efficient sharing while maintaining video quality.
Solution Approach 2:
The patent uses structured log data as an intermediary representation that contains all necessary video information in a highly compressed form. This intermediary data structure serves as a efficient placeholder that enables video sharing with minimal data transmission.
Data Source
AI summary
A system that acquires, from a terminal device, log data related to progress of the game generated by the terminal device; creates the video based on the log data; generates metadata related to progress of the game based on the log data; associates the metadata with the video; and outputs the video and associated metadata.
