Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to the flow chart that Fig. 1, Fig. 1 are the implementation method preferred embodiments of the most multiple secondary screens of main screen synchronous sharing of the present invention.As it is shown in figure 1, the described main screen synchronous sharing of embodiment of the present invention offer is to the implementation method of the most multiple secondary screens, including step:
The File Open instruction specifying extension name is detected by step S100, main screen terminal in real time, then obtains the file data that desktop present displayed content is corresponding when this document OPEN being detected；
Step S200, when secondary screen terminal sets up Wi-Fi wireless connections with main screen terminal, then file data is sent to secondary screen terminal by main screen terminal；
Step S300, secondary screen terminal receive described file data, and show described file data.
The present invention by Wi-Fi module by file data synchronous transfer corresponding for main screen terminal present displayed content to multiple secondary screen terminal connected by Wi-Fi therewith, pair screen terminal include that user carries with such as intelligent terminal such as mobile phone, panel computer, notebook computers.When secondary screen terminal receives described file data, reduce described file data (decompression as described in file data), and generate the local file identical with file data type, achieving main screen terminal and the file-sharing of secondary screen terminal that user carries with, the utilization rate substantially increasing secondary screen terminal is that user understands that conference content provides a great help.
Further, include before described step S100: when main screen terminal detects that preassembled desktop shares application program launching, then open Wi-Fi Hotspot.Please refer to Fig. 2, Wi-Fi module in main screen terminal 10 is as local Wi-Fi Hotspot, Wi-Fi module in each secondary screen terminal 20 is then as local Wi-Fi client, main screen terminal 10 transmits, by local Wi-Fi Hotspot, the most multiple secondary screen terminal of file data that its desktop shows, so that when there is no broadband Wi-Fi network, also can realize data transmission at a high speed sharing, it is to avoid the restriction of Wi-Fi wide area broadband network, i.e. be independent of broadband Wi-Fi wide area network.
Such as, when showing PPT file in the main screen terminal in meeting room, and by projector projects to projection screen, when main screen terminal detects that described desktop shares application program launching, then main screen terminal program can be opened the Wi-Fi module in main screen terminal and be set to Wi-Fi Hotspot Host, Wi-Fi Hotspot has a default title, such as " PPT_Share ", user can revise this Wi-Fi Hotspot title in the desktop of main screen terminal shares the setting option of application program, can arrange the login password of this Wi-Fi Hotspot or be set to without password simultaneously.After being provided with and be properly functioning of main screen terminal, file data currently displaying on its desktop is shared away with broadcast mode by the Wi-Fi Hotspot of the machine.
Further, described appointment extension name includes document suffix, form suffix, lantern slide suffix and video suffix.Concrete, described document suffix includes that doc, docx etc., described form suffix include that xls, xlsx etc., described lantern slide suffix include that ppt, pptx etc., described video suffix include avi, mp4, rm, rmvb etc..Above-mentioned file extension is only used for citing, is embodied as being not limited to above-mentioned listed item.
Further, described step S200 specifically includes:
The desktop of user is shared application program launching and is detected by step S201, secondary screen terminal, then judges whether to search for the Wi-Fi Hotspot in the range of specifying when desktop shares application program launching when detecting；
