Media Stream Synchronization via Time Difference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional platforms face challenges in efficiently processing and synchronizing numerous media streams from multiple user devices during interactive sessions, such as multiplayer games, due to varying lag and time delays, which human editors struggle to manage manually.
Innovation Solution
A server system that identifies a predetermined attribute in each stream, determines the time difference between streams, and synchronizes them using a stream processing server with a stream analysis engine and buffer engine, ensuring synchronized output to a recipient device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If human editors manually edit and synchronize streams, then synchronization precision can be achieved, but processing time and labor requirements increase significantly when dealing with numerous streams
Solution Approach 1:
The system enables automatic self-synchronization of media streams by having the server itself perform the synchronization operation without requiring human editors. The server analyzes streams, identifies synchronization markers, and automatically adjusts timing to align streams, thereby eliminating manual labor while maintaining precision.
Solution Approach 2:
The patent replaces the mechanical manual editing process with an automated computer-based system. The server uses software algorithms to detect synchronization markers (such as audio cues or timestamps), calculate time differences between streams, and automatically synchronize them, substituting human manual operations with automated mechanical processes.
2Manufacturing precision
If human editors manually process each stream individually, then synchronization accuracy can be maintained, but the complexity of managing multiple streams increases
Solution Approach 1:
The server system performs multiple functions simultaneously: receiving streams from multiple user devices, analyzing each stream for synchronization markers, calculating time differences, and synchronizing all streams. This multi-functional approach consolidates what would otherwise require multiple separate manual processes into a single automated system.
Solution Approach 2:
The system continuously monitors the timing of synchronization markers in each stream and uses this feedback to calculate and adjust time differences. By analyzing the actual timing data from the streams themselves, the system automatically determines the necessary synchronization adjustments without requiring complex manual coordination.
3Ease of operation
If streams are processed without automatic synchronization, then manual control is maintained, but time delay and lag differences between streams increase
Solution Approach 1:
The server performs preliminary analysis of each stream to identify synchronization markers and calculate time differences before the actual synchronization process begins. By preparing the timing information in advance, the system can then efficiently synchronize the streams without requiring manual intervention during the synchronization process itself.

AI summary
Systems and methods for intelligent synchronization of media streams are provided. A server may receive streams corresponding to an interactive session and sent over a communication network from user devices in the interactive session. A predetermined attribute may be identified as present in each of the streams, but received at different times by the server. The server may determine a time difference between a time that a predetermined attribute in a first stream of the streams was received and a time that the predetermined attribute in a second stream of the streams was received. The first stream and the second stream may then be synchronized using the time difference and provided to a recipient device.
