Fig. 1 is the inventive method flowchart.
[embodiment]
As shown in Figure 1, the present invention, based on the multiple terminals synchronous broadcast method of time-stamping messages, comprises the steps:
Step S1: each terminal downloads task list in same local area network is to local, and task list comprises multiple task, each task ID, the initial reproduction time of each task pre-set and terminates reproduction time;
Specifically, following detailed step is comprised:
Step S101, by networked information delivery system management platform, add material and edit each task and form task list, for the playing task of each terminal, playing task is made up of one or more subtask usually, subtask mainly refers to the playing task of same task in different time sections, each subtask pre-sets according to time demand, and subtask can be made up of one or more material, and described material refers to video, picture or audio file. Task list is generally a form, describe multiple need play task ID, and in each task each subtask initial reproduction time and terminate the above-mentioned task list of reproduction time be not limited to tabulated form, also can be other forms of file.In fact, the task list of the present invention also records the material ID in each task and subtask and the initial time of material broadcasting, that is, task of the present invention may refer to task or subtask itself, also may material in finger task, for convenience of description, and when those skilled in the art all understand, but it is not launched explanation by the present invention.
Step S102, each terminal task list being issued in same local area network, the time that issues of task list is determined as required by the manager of networked information delivery system, it is necessary to then re-start issuing of new task table when upgrading task list;
Step S103, the same task list of each terminal downloads, each terminal all broadcasts download message to local area network at regular intervals in download process, this download message comprises to be downloaded and completes to download two kinds of download states, this download message all can be received by each terminal in local area network and management platform, the download message that transmission is being downloaded is continued before any terminal, until after having downloaded, send to local area network or claim broadcast to complete download message, then wait that other-end has been downloaded, when the message state that part terminal sends is for downloading, illustrate that part terminal downloads does not complete, and after all terminals are all sent completely the download state message of download, illustrate each terminal all finish the work table download,
After step S2, all terminal downloads complete, each terminal take current point in time as benchmark, calculates the task of current point in time needs broadcasting according to task list;
Step S3: the terminal completing to calculate forms scheduling message and is broadcast to local area network, this scheduling message comprises task ID and initial reproduction time, each terminal is receiving scheduling message while calculating the task of needing broadcasting, if the initial time that in the scheduling message received, other-end calculates is more late than the initial time that this terminal calculates, just need playing of task as benchmark taking the initial time dispatched in message; If the initial time that other-end calculates is more Zao than the time that this terminal currently calculates or identical, the initial time just currently calculated taking this terminal calculates as benchmark;
Specifically, following detailed step is comprised:
Step S301:
By calculating, reference time point needs the task of broadcasting to form scheduling message to every station terminal, this scheduling message comprises task ID and initial reproduction time, and in local area network, broadcast this scheduling message, concrete method of calculation are as follows: initial reproduction time is current point in time, also it is exactly the time point started for calculating, such as wherein a terminal local display calculates the time point started is 16:40:00, namely current point in time is 16:40:00, now, this terminal starts to calculate, specifically, travel through whole task list, find out initial reproduction time the earliest in all tasks pre-set, the initial reproduction time the earliest such as found is 08:05:32, then start at a little by the time of this time, find out and start at a little nearest task from this time, namely have found task 1, then, the termination end time according to this task 1 is the time start at a little, find out and start at a little nearest task from this time, it is next task, then, start at a little taking termination end time as the time of next task, find out the 3rd task of needing to play, analogize with this, until calculating which task corresponding to current point in time be, such as, the termination end time of (n-1)th task is 16:39:00, then continue to start at a little taking termination end time as the time of this task, find out and start at a little nearest task from this time, it is the n-th task, if, the initial reproduction time of this n-th task is 16:40:00, then: scheduling message display: task ID is the ID of the n-th task, initial time is 16:40:00, if, the initial reproduction time of this n-th task is 16:40:30, then: scheduling message display: task ID is the ID of the n-th task, initial time is 16:40:30,
First the terminal formation scheduling message completing to calculate sends and is broadcast to local area network, and such as 3 first, terminal completes to calculate, and sends scheduling message: task n, and initial time is 16:40:30; It should be noted that, usual terminal need not be calculated initial reproduction time the earliest when calculating every time from all tasks, when just calculating first, if certain station terminal is when the midway time adds in the ranks synchronously play, such as power-off restarting, or the situation that fault heavily opens. The terminal being in normal play only need to carry out calculating in the continuity of last computation result.
Step S302:
The terminal that rear calculating completes carrys out the task of Adjustable calculation to current point in time needs broadcasting according to the scheduling message of self calculation result with the other-end received, and forms scheduling message and be broadcast to local area network, and scheduling message comprises task ID, and initial time;
The first situation: such as terminal 7 is the 2nd terminal that calculating completes, the task that he calculates is n-1, initial time is 16:40:00, namely the initial time (for 16:40:30) that in the scheduling message received, other-end calculates is more late than the initial time that this terminal calculates, just task taking the initial time 16:40:30 that dispatches in message as playing needed for benchmark, obtain this task ID, it is task n;
2nd kind of situation: such as terminal 7 is the 2nd terminal that calculating completes, the task that he calculates is n, initial time is 16:40:30, namely the initial time (for 16:40:30) that in the scheduling message received, other-end calculates is identical with the initial time that this terminal calculates, the initial time 16:40:30 just currently calculated with this terminal is as the criterion, calculate required playing of task, obtain this task ID, be task n;
The third situation: such as terminal 7 is the 2nd terminal that calculating completes, the task that he calculates is n, initial time is 16:41:00, namely the initial time (for 16:40:30) that in the scheduling message received, other-end calculates is more Zao than the initial time that this terminal calculates, the initial time 16:41:00 just currently calculated with this terminal is as the criterion, calculate required playing of task, obtain this task ID, be task n;
Other-end is analogized with this, and principle is being as the criterion with initial time evening, calculates the task ID of required broadcasting;
After last terminal completing to calculate sends scheduling message, each terminal can define unified calculation result, namely the required task ID play with or material ID be consistent, and reproduction time is consistent.
Step S4: after each terminal completes to calculate required playing of task, broadcast starts message to local area network, wait afterwards, until all terminals all send one starts message, all terminals wait a period of time more in the lump afterwards, it is better that time cycle is set to 100ms, synchronously playing afterwards, described beginning message comprises task ID and initial reproduction time; The last synchronous step S3 of broadcasting calculates the broadcasting content corresponding to task needing to play, for the embodiment of last step, i.e. task n;
Specifically, such as terminal 1, sends at 16:45:00 and starts message, starts message and is:
16:45:01, startvideo1
Terminal 2, sends at 16:45:00 and starts message, starts message and is:
16:45:05, startvideo1
Analogizing with this, all terminals all send beginning message, until last terminal is sent, after all terminals wait 100ms in the lump, all terminals start synchronously to play in step S3 the broadcasting content corresponding to task calculated;
Step S5: after a upper task plays, add up this reproduction time by reproduction time corresponding for task ID, taking this time as benchmark, return to step 3, the task ID needing next time to play is calculated to continue, form scheduling message, after waiting whole calculating to terminate, then go to step S4 and start synchronous broadcasting;
Wherein, each terminal when playing every a period of time broadcast playback message to local area network, play message and comprise task ID and initial time. The described time cycle is set as 5 seconds. It is the content informing that other terminal is play now every the object of a period of time broadcast playback message, again log in after such as a certain terminal fault, the broadcasting message in local area network can be received, with this calculate task that this terminal needs to play and or material ID, synchronous with what ensure with other-end.
The broadcast when arbitrary task stops playing of each terminal stops message to local area network, and this stopping message comprising task ID and stand-by time. Its objective is to ensure that every station terminal can synchronously stop;
In sum, the present invention comes synchronous in local area network by time-stamping messages, multiple stage terminal is made to play simultaneously and stop identical playing task, the switching effect of material is also all consistent, client can receive consistent information on multiple stage display equipment, efficiently solve multiple stage terminal and play the problems such as inconsistent information, information displaying be mixed and disorderly, the effect higher-end of Information issued simultaneously, thus promote Information issued benefit. During the identical material task of the multiple stage terminal storage arranged in same place (as in market, bank, supermarket) such as the present invention, terminal sends in local area network and receives synchronized timestamp message, control terminal scheduling task is carried out by synchronized timestamp message, make the terminal in local area network starting shooting simultaneously, separate unit terminal closedown or can both accomplish to play simultaneously and switch consistent video, audio frequency, picture materials under heavily opening situation, and synchronization delay time controling is in 0.1 second.
This patent adopts Ethernet packet synchronisation mechanism to realize synchronous broadcasting, synchronous content comprises image, text, audio frequency and video, this kind of method of synchronization can adopt the wireless modes such as wifi or other wired modes transmit, can also the synchronous terminal of flexible configuration, and the broadcasting content of configuration synchronization terminal, such as in 100 station terminals, arbitrarily configuration 40 or how many synchronous a kind of contents wherein can be realized, other 50 other contents synchronous, and this kind of flexible configuration does not need to increase extra equipment, for other synchronous mechanism with the obvious advantage, the synchronous mechanism that other such as VGA simulate divider and the realization of VGA digital distribution device can not accomplish this kind of flexible configuration, need to realize flexible configuration by increasing extras, therefore, the synchronous mechanism described in this patent, has management flexibly, and configuration is simple, data signal that can be synchronously more multi-class, reduces the useful effects such as hardware cost.
Although the foregoing describing the specific embodiment of the present invention; but it is familiar with those skilled in the art to be to be understood that; specific embodiment described by us just explanation property; instead of the restriction for the scope to the present invention; those of ordinary skill in the art in the modification of the equivalence done according to the spirit of the present invention and change, in the scope that the claim that all should be encompassed in the present invention is protected.
