Communal Media Synchronization via Playback Control Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communal media systems face synchronization challenges when multiple users stream or view multimedia content across different devices with varying network configurations, leading to lag times and inconsistent content delivery during communal sessions.
Innovation Solution
A communal media system that includes an authentication system, integration system, and synchronization system to authenticate access, integrate with streaming applications, and synchronize multimedia content delivery across multiple devices, ensuring simultaneous and lag-free delivery of recordings and social media content by exchanging playback control messages and using timestamp structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users stream multimedia content simultaneously across different devices with varying network configurations, then communal viewing capability is enabled, but synchronization and lag time consistency deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary that receives multimedia content from a first device and distributes it to multiple second devices. The server acts as a central coordination point that manages content delivery and timing, ensuring synchronized playback across all devices regardless of their individual network configurations. This mediator approach resolves the contradiction by decoupling the direct peer-to-peer synchronization problem while maintaining communal viewing capability.
Solution Approach 2:
The system performs preliminary actions by pre-synchronizing playback timing information before content distribution. The server prepares and sends timing data to all participating devices in advance, allowing them to coordinate their playback sessions with consistent timing. This preliminary synchronization action ensures that all devices are ready to play content simultaneously, resolving the lag time inconsistency issue while preserving the adaptability of multi-device communal viewing.
2Measurement precision
If playback control messages are exchanged to synchronize content delivery, then synchronization accuracy is improved, but system complexity increases
Solution Approach 1:
The patent employs homogeneous timing mechanisms across all devices, using standardized playback control messages with consistent timestamp formats and synchronization protocols. By implementing uniform timing standards and message structures throughout the system, the patent achieves high synchronization accuracy while minimizing the complexity that would arise from heterogeneous approaches. This homogeneity principle allows precise coordination without requiring complex device-specific synchronization logic.
3Loss of time
If timestamp structures are used to coordinate playback timing, then delivery simultaneity is improved, but data processing overhead increases
Solution Approach 1:
The system implements partial timestamp processing by sending and utilizing only the essential timing information needed for synchronization, rather than comprehensive timing data. The playback control messages include selective timestamp elements that provide sufficient information for coordinated playback without the overhead of complete timing records. This partial action approach achieves delivery simultaneity while reducing data processing overhead and energy consumption.
Data Source
AI summary
A method for delivering multimedia content during a communal session at a media system commutatively coupled with a streaming application. The method includes authenticating access to multimedia content for user devices participating in a communal session, receiving a first recording from a first user device, the first recording being generated from a first set of cameras of the first user device, receiving social media content generated the user devices, the social media content including a second recording generated simultaneously with the first recording on the first user device, the second recording being generated from a second set of cameras of the first user device, and synchronizing delivery of the first recording and the social media content by exchanging playback control messages with the streaming application to direct synchronized transmissions of the first recording and the social media content to the user devices.
