Group Capture Synchronization for Multi-Perspective Gameplay Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to capture and share immersive video and audio experiences from multiple user perspectives during cooperative or competitive gameplay, missing memorable or entertaining in-game and social events.
Innovation Solution
A system and method for group capture of video and audio information from multiple client devices, allowing users to initiate a group capture request, associate individual captures from each device, and provide access to a unified group capture, including video, audio, and chat audio, synchronized by a server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single-device capture systems are used, then the system complexity remains low, but the capture experience lacks immersion and multiple perspectives
Solution Approach 1:
The system segments the capture function across multiple client devices, where each device independently captures video and audio from its own perspective. This segmentation allows the system to collect diverse perspectives without requiring a single complex centralized capture device, thus improving capture perspective diversity while keeping individual device complexity low.
Solution Approach 2:
The server merges individual captures from multiple client devices into a unified group capture. By combining video streams, audio streams, and chat data from multiple sources, the system creates an immersive multi-perspective experience while distributing the complexity burden from individual devices to the centralized server.
2Loss of information
If multiple individual captures are collected from different devices, then the immersion and social experience improve, but the association and synchronization of captures becomes complex
Solution Approach 1:
The server uses feedback mechanisms including capture group identifiers, timestamps, and device identifiers to automatically associate individual captures with the correct group capture. This feedback-based association system retains social context and temporal relationships without requiring complex manual synchronization, thus improving social context retention while simplifying the association process.
Solution Approach 2:
The server implements a universal capture group identifier that works across all client devices in the group. This universal identifier system allows the server to associate captures from different devices with different capture types (video, audio, chat) to the same group capture, retaining social context while simplifying the association complexity through a standardized approach.
3Productivity
If group capture requests are transmitted to multiple devices, then the collaborative capture experience improves, but the network communication overhead increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing capture group memberships and device relationships before capture requests are initiated. This preliminary organization allows the server to efficiently transmit capture requests to multiple devices using pre-computed device lists and group configurations, thus improving capture initiation efficiency while reducing network communication overhead by avoiding repeated discovery and negotiation.

AI summary
A method of capturing video and audio information includes, at a server computer, determining a capture group that includes at least a first client device and a second client device. The method further includes receiving a group capture request and transmitting an individual capture request to at least the second client device. The method further includes receiving a first individual capture from the first client device and a second individual capture from the second client device, associating the first individual capture with the second individual capture in a group capture, and providing access to the group capture to at least one of the first client device and the second client device.
