Data are sent to specified handset 103 and/or main controller 102；
The specified handset 103 and/or main controller 102 receive the stream medium data, show after being decoded.
Specifically, any one existing screenshotss technology can be used in screenshotss, screenshotss movement is beaten on server 101 from software
With regard to carrying out always from when opening.Further, since the picture pixel of usually screenshotss can be larger, and the handset 103 attended a meeting might have very
More, in order to mitigate 101 pressure of server and guarantee with screen transmission speed, it is therefore desirable to do be distributed to after compression processing again it is described
Handset 103 and/or main controller 102.
It is shown in Figure 2, on the other hand, a kind of method of multi-terminal equipment Display on the same screen of the present invention, the terminal device
Including the server 101, main controller 102 and several handsets 103 being connected by network；Method includes:
S201, main controller 102 receive the opening request of specified file, the specified file are opened, by the text of the file
The information such as file type, the file store path of part are sent to server 101；
S202, server 101 downloads the specified file according to the store path, and is used according to the file type
Corresponding software is opened the specified committee paper and is shown in the display equipment；
S203, the server 101 by the content that shows of display equipment by certain frame per second screenshotss compressed encoding at
Stream medium data is sent to specified handset 103 and/or main controller 102；
S204, the specified handset 103 and/or main controller 102 receive the stream medium data, show after being decoded.
Further, server 101 opens the specified committee paper simultaneously using corresponding software according to the file type
After being shown in the display equipment, further includes:

After the main controller 102 receives the processing success message, display control message is sent to the server
101；
The server 101 receives the display control message, and according to the control instruction in the display control message
Control the display of the specified committee paper on the display device.
Further, the file store path is URL format, and the main controller 102 is serviced by starting Http by institute
It states the information such as file type, the file store path of the file of file and is sent to the server 101.
It is shown in Figure 3, it is the data transmission stream journey figure of a variety of end equipment Display on the same screen methods of the invention, comprising:
A, main controller 102 open file, it will view file data is passed through in router or data exchange with original format
The heart 104 is wirelessly completely transferred to host computer (or server 101)；
B, 101 resolution file data of server, downloads the file, is solved by the corresponding software of pre-installation to file
Code is handled and is shown；
C, server 101 carry out screenshotss compression to the content that screen is shown using screenshotss program and condensing routine；
D, the content that server 101 shows screen pass through Wi-Fi network point by certain frame per second in the streaming media
(transmission) is sent out to several handsets 103 and/or main controller 102；
D0~Dn, main controller 102 and handset 103 decode by Wi-Fi network receiving stream media data and show picture.
It is shown in Figure 4, it is the data transmission stream journey figure of a variety of end equipment Display on the same screen methods of the invention.In attached drawing,
In the process, main controller 102 is sent to the instruction of server 101 and server 101 is sent to handset 103 or main controller 102
All instructions is all based on Transmission Control Protocol to realize.It is instructed corresponding to one, sender's (such as main controller 102 or server 101) presses
It is packaged and instructs according to predetermined format, recipient's (such as server 101, handset 103 or main controller 102) refers to according to predetermined format unpacking
It enables, to realize the parsing to instruction message.
The operational order that the main controller 102 is sent to server 101 includes push specified file, upper and lower page turning, maximum
Change etc..It includes Display on the same screen etc. that the server 101, which is sent to handset 103 or the instruction of main controller 102,.
By taking the process for pushing PPT as an example.Command definition is CMD_PLAY_PPT=9, and customized data are pressed in this order
The path URL of order and PPT is broken into data packet by packet format, and the server receives after data packet also by same format solution
Analysis obtains order and the path PPT.Data packet format is as follows:
The packet header that magic ... ... is 2byte identifies
Version ... is the data packet version number of 2byte
Command ... is the order of 2byte
Reserved ... is the reserved bit of 1byte
Length ... is the length of data behind 2byte
Data ... content is subject to actual order, and when such as pushing PPT, the content in data is mainly the path of PPT
Information.
It is of course also possible to there is other group packet modes, the embodiment of the present invention is not particularly limited.
Above-described embodiment is intended merely to illustrate the present invention, and is not used as limitation of the invention, as long as according to this hair
Bright technical spirit is changed above-described embodiment, modification etc. will all be fallen in the scope of the claims of the invention.
