Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current recording marking systems only support single-device functionality, leading to inefficiencies in information acquisition and increased network bandwidth usage due to redundant data and time delays caused by complex synchronization processes.
Innovation Solution
A multi-device recording synchronization method and system that allows synchronization of recording marking and control between multiple devices using a master-slave architecture with a remote procedure call framework, enabling file sharing and timestamp management to ensure data consistency and reduce network bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-device recording marking system is used, then the system complexity is low, but the information acquisition efficiency is reduced and multiple devices cannot synchronize marking
Solution Approach 1:
The system divides recording marking devices into master devices and slave devices. Master devices generate and manage marking data structures, while slave devices synchronize and use these structures. This segmentation allows multiple devices to perform recording marking in the same conference without requiring all devices to have full functionality, thus improving adaptability while controlling complexity.
Solution Approach 2:
The patent introduces a standardized mark data structure as an intermediary that enables communication and synchronization between master and slave devices. This data structure acts as a common language that different devices (potentially running on different systems with different development languages) can understand, facilitating multi-device coordination without direct complex inter-device communication protocols.
2Productivity
If mark data structure comparison is performed during synchronization, then information acquisition efficiency is improved, but time loss occurs and network bandwidth is consumed
Solution Approach 1:
The system performs preliminary actions by having master devices generate marking data structures in advance during the recording process. Slave devices synchronize by receiving and applying these pre-generated structures rather than performing complex real-time comparisons. This approach maintains information acquisition efficiency while reducing synchronization time delay and network bandwidth consumption.
Solution Approach 2:
The patent extracts only the essential marking information into a standardized mark data structure that is transmitted during synchronization. Instead of comparing entire recording datasets or performing comprehensive data structure comparisons, the system extracts and transmits only the critical marking elements, thereby improving information acquisition efficiency while minimizing time loss and network bandwidth usage.

AI summary
The present disclosure discloses a multi-device recording synchronization method and system, and a conference system, and belongs to the field of recording marking. For the problem in the prior art that a device that supports a recording marking function only supports generation and use on a single device, the present disclosure provides a system, including one master and a plurality of slaves. The master is connected to the plurality of slaves. The master operates according to the instruction sent by the slave and broadcasts state information globally. Through a network connection between the master and the slave, the master stores, on the master, recording and marking data sent by the slave, and synchronizes the data between devices, and a multi-device recording marking and synchronization system is applied to a conference system. The present disclosure is very convenient for use and has simple operation logic and low system costs.
