Wireless Time Code Synchronization via Serial Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time code synchronization methods in wireless communication systems are inaccurate, leading to large errors and workloads when synchronizing multiple video and audio devices in film and television production environments.
Innovation Solution
A method for wireless time code synchronization using a network system with a master node and slave nodes, where the master node periodically sends data packets containing a first time code and serial number information, allowing slave nodes to compensate and synchronize their time codes by determining a second time code based on the serial number information, thereby achieving accurate synchronization.

Engineering Contradiction Analysis
1Measurement precision
If time code information is set manually for each machine, then time code synchronization can be achieved, but the workload increases significantly and errors occur
Solution Approach 1:
The system enables automatic time code synchronization where the master node automatically distributes time code information to slave nodes through wireless communication. Each slave node automatically receives and synchronizes to the master node's time code, eliminating the need for manual configuration and reducing human error while maintaining high synchronization accuracy
Solution Approach 2:
The master node acts as an intermediary that centralizes time code generation and distribution. Instead of manually configuring each device individually, the master node serves as a single point of control that automatically manages time code synchronization across all slave nodes, significantly reducing operational workload
2Ease of operation
If wireless synchronization is used, then operation workload is reduced, but synchronization accuracy decreases
Solution Approach 1:
The system incorporates feedback mechanisms where slave nodes receive time code data packets from the master node containing serial number information. Each slave node uses this feedback to calculate compensation values based on transmission delays and compensates its local time code accordingly, maintaining high synchronization accuracy despite wireless communication variations
Solution Approach 2:
The system dynamically adjusts synchronization parameters by incorporating serial number information in data packets. Slave nodes use these parameters to calculate and apply compensation values that account for wireless transmission variations, thereby maintaining accurate synchronization while benefiting from wireless operation
