Problems solved by technology

[0006] Realize synchronous sharing between devices through LAN connection, that is, use each terminal as a display to display the content on the display screen of the data delivery terminal. This method is very stressful for the device, causing the delivery device and the connected device to freeze, and the effect is relatively small. Difference

Embodiment 1

[0051] Embodiment 1 of the present invention provides a low-delay terminal synchronization method used in a synchronization system. The synchronization system includes a management terminal and at least one terminal, such as figure 1 As shown, the specific process is as follows:

[0052] First, the staff set the synchronization parameters through the operation on the web system interface of the management terminal, and set the display settings for the data content that needs to be displayed and output synchronously, set the display template, sequence content and time of the playback output, start each terminal, manage The terminal establishes a udp connection with each terminal.

[0053] Afterwards, the management terminal sends the start synchronization command according to the synchronization terminal of this connection set. After each terminal receives the start synchronization command, it parses the command and obtains the data to be displayed and output, including the fol...

Embodiment 2

[0066] Embodiment 2 of the present invention provides a low-delay terminal synchronization system based on the synchronization method described in Embodiment 1 above. The system includes a management terminal and a terminal, such as figure 2 As shown, the terminal is provided with several, and establishes a connection with the management terminal through the network. In this embodiment, the udp transmission protocol is used for data communication between each terminal and the management terminal;

[0067] In this embodiment, the management terminal realizes the web-based operation management system through java, and the staff can operate, view and manage on the web interface, configure the synchronization parameters, set the synchronization output data according to the template, and send the start synchronization to the terminal Instructions, when the management terminal and the terminal communicate interactively, the steps of the above-mentioned synchronization method are imp...

Abstract

The invention provides a low-delay terminal synchronization system and method, wherein the system comprises a management end and a plurality of terminals, the management end is in network connection with the terminals and performs data and control instruction transmission, the management end sends synchronization instruction data to each terminal, determines a main terminal from each terminal according to an IP address sequence in the synchronization instruction data, and establishes tcp communication connection with other terminals by taking the main terminal as the center, and sends a synchronization instruction to the other terminals by the main terminal after the connection is established. The management end is used for regulation and control management, the main terminal is determined through the IP address, the main terminal is used as a synchronization core to send the synchronization instruction to the other terminals, synchronization delay is reduced, and the pressure of the management end is relieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a low-delay terminal synchronization system and method. Background technique [0002] With the development of communication technology, synchronous display of data can be realized between terminal devices. [0003] At present, the synchronous display between devices generally includes two methods. One is based on the connection between hardware to perform data synchronization and display output; the other is to perform data synchronous display output based on network transmission; but it has the following advantages and disadvantages: [0004] 1. Connect the main device and the device to be synchronized directly through the high-speed transmission line to realize data transmission and synchronization. This method of data synchronization output is suitable for display synchronization in a small area, such as meeting rooms or laboratories. It is used for small indoo...
