Step 204, operational order is sent to target terminal, operational order is executed for target terminal for page file
Operation, to complete to be broadcast live.
Referring also to Fig. 4, operational order first can be sent to second server by local terminal, then will be received by second server
Operational order is sent to target terminal, to realize the transmission of operational order.After target terminal receives operational order,
It is directed to according to operational order and operation is executed according to the page file that link is got.Wherein, it carries in operational order for area
Divide CMD (Command, order) mark of operational order meaning, CMD mark can be by local terminal, second server and target terminal about
Surely the agreement obtained is provided.For example, the CMD that parsing operational order carries is marked after target terminal receives operational order
Knowledge obtains the operational order as auto-building html files instruction, then target terminal can instruct loading page file according to the auto-building html files,
To realize the generation of webpage.For other operational orders included in step 203, no longer it is repeated here one by one herein.
It should be noted that operational order may occur in transmission process after local terminal sends operational order
It loses.In this case, the operation that page file has executed is directed to for local terminal, target terminal is not due to receiving operational order
And fail to execute identical operation for the page file of target terminal, so as to cause the page file of local terminal and target terminal
State is different.Therefore, optionally, after operational order being sent to target terminal, method provided by the present embodiment further include:
Status command is sent to target terminal, status command indicates the first state of the page file of local terminal, and first state includes the page number
And the animation display effect based on the page number, status command for target terminal by the second state of the page file of target terminal with
First state is synchronous.
Wherein, trigger to the mode that target terminal sends status command includes: as shown in figure 8, local terminal starting timer, fixed
When device for trigger local terminal every the reference time to second server send status command, second server storage state instruct institute
The first state of instruction, and the status command received is sent to target terminal, target terminal confirms this according to status command
Whether the first state at end and the second state of target terminal are synchronous.Validation testing can be found in Fig. 9, and target terminal first confirms that this
Hold webpage shown by the PPT page the page number (Page ID) whether the page number one with the PPT page shown by target terminal webpage
Cause, then confirm animation display effect on the page shown by local terminal webpage quantity (Page Step) whether with target terminal
The quantity of animation display effect is consistent on the page shown by webpage.
If one or two in the page number and animation display effect based on the page number is inconsistent, confirm first state with
Second state is asynchronous.For example, in local terminal web displaying PPT first page third animation display effect, and target is whole
First animation display effect for holding first page of web displaying PPT, then confirm that first state is asynchronous with the second state.It should
In the case of, target terminal can obtain the operational order as corresponding to the second state to first state from second server.
In the present embodiment, operational order can be numbered sequentially in time, such as by the first of first page
The corresponding operational order number of a animation display effect is 1, by the corresponding behaviour of second animation display effect of first page
Making order number is 2, is 3 by the corresponding operational order number of first animation display effect of second page, and so on.
The then operational order as corresponding to the second state to first state that target terminal obtains, comprising: it is corresponding to obtain the second state
The number of operational order is to the numbered operational order of institute between the number of the corresponding operational order of first state.For example, this
The first state of end webpage is to show first animation display effect of second page in PPT, the i.e. corresponding behaviour of first state
The number for making to instruct is 3；And the second state of target terminal is to show first animation display effect of first page in PPT
