Content Distribution Synchronization Using Delay Time Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern distribution systems, synchronization between reproduction devices and distribution devices is often lost due to delays in content data distribution, leading to desynchronization of outputs across multiple distribution destinations.
Innovation Solution
A synchronization setting device, comprising a processor and memory, acquires and outputs delay times to reproduction and distribution devices, allowing them to adjust their timing and maintain synchronization, thereby ensuring synchronized outputs across the network.

Engineering Contradiction Analysis
1Speed
If content data is distributed through a network requiring encoding and decoding, then data can be transmitted across the network, but delay time increases and synchronization is lost between distribution destinations
Solution Approach 1:
The system performs preliminary actions by pre-calculating and setting delay times for distribution devices and pre-synchronizing clocks between reproduction and distribution devices before content distribution begins. This advance preparation ensures that when distribution occurs, the timing relationships are already established, preventing synchronization loss despite network delays
Solution Approach 2:
The system implements feedback mechanisms by measuring actual delay times in the distribution path and using this information to adjust delay time settings. The synchronization setting device continuously monitors and refines timing parameters based on observed performance, ensuring synchronization is maintained even as network conditions vary
2Reliability
If delay time is set in distribution devices to synchronize outputs, then synchronization between distribution destinations is achieved, but additional control complexity is required to manage delay settings
Solution Approach 1:
The synchronization setting device serves as an intermediary that automatically manages delay time settings and clock synchronization between the reproduction device and distribution devices. This mediator handles the complex timing calculations and adjustments, shielding users from the complexity while ensuring reliable synchronization
Solution Approach 2:
The system enables self-service by allowing distribution devices to automatically adjust their delay times based on settings provided by the synchronization setting device. The devices self-regulate their timing without requiring manual intervention, reducing operational complexity while maintaining synchronization reliability
3Measurement precision
If clock synchronization is performed between reproduction and distribution devices, then timing alignment is achieved, but communication overhead and setup complexity increase
Solution Approach 1:
The clock synchronization process uses feedback by having the synchronization setting device measure the actual timing relationships between devices and adjust synchronization settings based on observed deviations. This closed-loop approach achieves high timing precision while automating the communication process, reducing the burden on users

AI summary
A synchronization setting device and a system include at least one memory storing instructions, and at least one processor that implements the stored instructions to acquire first delay time to be set in a first distribution device for distributing first content data, and output the first delay time to the first distribution device or to a reproduction device that provides the first content data to the first distribution device.
