Detailed description of the invention
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect:
Fig. 1 is structural schematic block diagram of the invention.
Specific embodiment
Hereinafter embodiments of the present invention will be disclosed with diagram.
As shown in Figure 1, multimachine real-time synchronization play system of the present invention includes server end 1, synchronized clock system 2 and terminal
Unit 3, each terminal unit 3 include a terminating machine group leader 31 and several terminating machine group members 32, terminating machine group leader 31 and terminal
Machine group member 32 is in communication with each other, it is contemplated herein that the actual effect of network transmission is arrived, between terminating machine group leader 31 and terminating machine group member 32
Quantity ratio is advisable with 1:N, and N is the natural number greater than 0 and less than 254.Server end 1 connects terminal by synchronized clock system 2
Unit 3, server end 1 include communication routing table 11 and video channel controller 12, and server end 1 is logical according to communication routing table 11
The terminating machine group leader 31 that video channel controller 12 connects terminal unit 3 is crossed, server end 1 is only and in each terminal unit 3
Terminating machine group leader 31 establishes connection, and group leader is responsible for being distributed to other end members with group, video channel after receiving video information
Controller 12 can control the on-off of video channel, and a system, which can according to need, is divided into multiple channels.Communicate routing table
11 can pre-establish after be stored in server end 1, be also possible to server end 1 power on after network according to remotely finger
It enables configuration file or database and automatically forms communication routing table 11 after defining relevant data structure.If be automatically generated
Routing table 11 is communicated, server end 1 will be grouped terminal unit 3, then cooperate synchronized clock system 2, and each terminating machine is real
Now networking is played simultaneously, or plays different content, and link content real-time synchronization, and different content is mutually indepedent, terminal herein
Machine is various regular price-line advertising machines or intelligent advisement player.The role that each terminating machine group leader 31 serves as group leader can be fixed,
It can also replace, it is non-exchange if it is fixation, then when this terminating machine breaks down, it will lead to entire terminal unit
Connection can not be established with server end 1.
Synchronized clock system 2 includes controlling terminal 21 interconnected and synchronised clock device 22, and synchronised clock device 22 is being controlled
