Object State Recording for Game Video Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for recording and replaying game videos are inefficient, leading to high data capacity requirements and increased load on user terminals, often resulting in degraded image quality and disrupted gameplay.
Innovation Solution
The method involves recording and replaying game videos using an object state recording technique, where objects in a 3D game environment are tracked for appearance, motion, and exit information, allowing for efficient data storage and reduced computational load by representing game states as image frames, thereby reducing data capacity while maintaining high image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional video recording methods are used to capture game videos, then complete video coverage is achieved, but data capacity becomes excessively large
Solution Approach 1:
The patent extracts only the essential elements needed to reproduce game video - object identification numbers, position coordinates, direction data, and image frame serial numbers - rather than recording complete video frames. This selective extraction of critical data points enables video reconstruction with minimal data storage requirements while maintaining complete video coverage.
Solution Approach 2:
The patent creates a simplified copy of the video data by recording only object state information (positions, directions, identification) rather than actual video frames. This abstract copy contains all necessary information to reconstruct the original video, dramatically reducing data capacity while preserving complete video coverage.
2Loss of information
If real-time video recording is performed on user terminals, then complete game video is captured, but computational load increases significantly
Solution Approach 1:
The patent extracts only essential object state parameters (identification numbers, positions, directions, frame serial numbers) from the game environment, avoiding the computationally intensive task of capturing and processing complete video frames. This extraction approach maintains complete video capture capability while dramatically reducing arithmetic unit load on user terminals.
Solution Approach 2:
The patent replaces the mechanical/video processing system with a data recording system. Instead of using video capture hardware and processing units to record actual video frames, the system substitutes this with a lightweight data collection mechanism that records only object state parameters, significantly reducing computational complexity.
3Device complexity
If video quality is reduced to lower computational load, then arithmetic unit load decreases, but image quality degrades
Solution Approach 1:
The patent creates an abstract data copy rather than a low-resolution video copy. By recording object state information (identification numbers, positions, directions) instead of actual video frames, the system maintains full image quality during replay while keeping arithmetic unit load low during recording. The quality is preserved because the original game objects are reconstructed from their state data rather than from degraded video frames.
