Distribution Server Signal Delay Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution systems face challenges in preventing the distribution of inappropriate video or audio signals due to errors in switching operations, as they lack effective mechanisms for real-time checking and modification of signal distribution, especially in environments where multiple workers are involved in editing tasks.
Innovation Solution
A distribution system comprising multiple clients and a distribution server that allows for the sharing and checking of switch operations, with each client having a switch unit and transmission unit to select and transmit signals, and the server having units to determine and adjust delays, ensuring accurate signal distribution by managing dependencies and switch information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If real-time distribution is executed without editing task completion, then instantaneousness is improved, but error in switching operation increases
Solution Approach 1:
The system creates a playlist in advance based on the switcher's selection signal before actual distribution occurs. This preliminary playlist serves as a reference guide that allows workers to review and verify switching operations beforehand, reducing errors while maintaining real-time distribution capability
Solution Approach 2:
The system provides feedback by displaying the created playlist to workers, allowing them to check whether switching operations are executed without errors. This feedback mechanism enables verification and modification of operations before distribution, improving reliability without sacrificing speed
2Productivity
If multiple workers share editing tasks, then productivity is improved, but complexity of operation increases
Solution Approach 1:
The system creates a copy of the switching operation plan in the form of a playlist that can be viewed and verified by multiple workers. This visual copy allows collaborative review without requiring complex coordination protocols, maintaining operational simplicity while enabling task sharing

AI summary
The present distribution system is formed by a plurality of clients enabled to receive a plurality of channels of signals and a distribution server enabled to output the plurality of channels of signals to respective clients. Each of the plurality of clients includes a switch unit and a transmission unit. The distribution server includes a plurality of transceiver units, a delay amount determining unit and a delay adjusting unit. The respective transceiver units output the plurality of channels of signals to the plurality of clients and receive selection information and dependent information from the respective plurality of clients. The delay amount determining unit determines delay amount to be instructed to the respective plurality of transceiver units based on the dependent information. The delay adjusting unit controls delay amount for the respective plurality of transceiver units based on the delay amount determined by the delay amount determining unit.
