Network Server Synchronizes Content Streams via 5G NR Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content delivery networks face challenges in synchronizing user-generated content with network programming due to discrepancies in time references caused by varying latency and bandwidth across different delivery channels, leading to unsynchronized overlays in composite content streams.
Innovation Solution
A computerized network server apparatus and method that receive and synchronize two digital content streams using control signaling to generate an enhanced content stream, adjusting playback timing to ensure correct temporal alignment, leveraging stable mechanisms like 5G NR for upload content and existing managed networks for network programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user-generated content is uploaded via ad hoc networks (e.g., Internet) and network programming is delivered via managed networks, then content delivery flexibility is improved, but time reference synchronization deteriorates due to varying latency and bandwidth
Solution Approach 1:
A synchronization server is introduced as an intermediary component that receives timing information from both the managed content distribution network and ad hoc networks, processes this information, and generates control signaling to synchronize content streams. This mediator resolves the synchronization conflict between flexible but unreliable ad hoc delivery and reliable but rigid managed network delivery.
2Device complexity
If content streams from different networks are combined without synchronization, then device complexity is reduced, but manufacturing precision deteriorates due to unsynchronized overlays
Solution Approach 1:
The system performs preliminary synchronization by obtaining timing information from both networks before combining content streams. The synchronization server pre-processes timing data and generates control signaling in advance, ensuring that when content streams are combined, they are already temporally aligned, thus achieving precise synchronization without adding complex real-time processing.
3Reliability
If playback timing is adjusted to achieve correct temporal alignment, then content synchronization is improved, but loss of time increases due to buffering and delay adjustments
Solution Approach 1:
The system dynamically adjusts playback timing based on actual timing information received from both networks. Rather than using fixed buffering delays, the synchronization server continuously monitors timing data and dynamically modifies playback schedules to achieve synchronization, minimizing unnecessary delays while maintaining temporal alignment.
