In the present embodiment, first mobile terminal has focus function, i.e., first mobile terminal can pass through itself WLAN arrange make itself as wireless WiFi；Other-end may be connected to the wireless WiFi and carry out wireless networking industry Business.Based on this, first mobile terminal can open focus function by the input operation for detecting, and obtain focus ground Location.

In the present embodiment, the first mobile terminal is projected to the screen that the data of the second mobile terminal are first mobile terminal Curtain data；It is to be understood that first mobile terminal gathers the on-screen data of itself display, and the on-screen data is delayed Deposit；Accordingly, the buffer address of the on-screen data is obtained.Used as a kind of embodiment, first mobile terminal can be by pre- If the on-screen data that rule collection shows itself, such as gather 30 frame on-screen datas each second and cache.

In the present embodiment, the first address is generated based on the hotspot address and the buffer address；Wherein, the focus ground Location is used for setting up wireless communication connection with first mobile terminal (i.e. described first is connected)；The buffer address is used for pointing to The on-screen data, the easily accessible on-screen data.As a kind of embodiment, described based on the hotspot address and described Buffer address generates the first address, so that the second mobile terminal is set up and first mobile terminal based on first address First connection, including：The identification information for characterizing first address is generated based on the hotspot address and the buffer address, with Make second mobile terminal support that the scanning identification information obtains first address, based on first address set up with First connection of first mobile terminal.In present embodiment, the identification information is specifically as follows 2 D code information or bar Code information etc.；Second mobile terminal can be scanned to the identification information by scanning tools, obtain the mark Know the first address of information representation, so that second mobile terminal is set up and the described first movement based on first address First connection of terminal.Used as another embodiment, second mobile phone users can also be manually entered first ground Location, so as to first address of second mobile terminal based on input is set up connect with the first of first mobile terminal Connect.Further, set up first based on first address with first mobile terminal when second mobile terminal to be connected Afterwards, first mobile terminal can by the on-screen data of real-time caching by first linkup transmit to the described second movement eventually End.

In the present embodiment, the first terminal is needed before collection on-screen data or during collection on-screen data The pace of change of the current screen display content of the first terminal is detected, is adjusted according to the display content pace of change of current screen Whole screen capture frequency；Wherein, can comprehensively be sentenced by obtaining the display content of current screen and the application instance of operation The situation of change of disconnected current screen.

As a kind of embodiment, the speed detection unit, apply belonging to the display content of current screen for obtaining Application type；Obtain the ruuning situation of application belonging to the display content of current screen；Display content institute according to current screen The application type of category application and ruuning situation determine the pace of change of current screen content.

Specifically, the type for being in advance based on application determines the first pace of change of current screen content；Then in conjunction with application Ruuning situation determine the second pace of change of current screen content.The class that is first applied according to belonging to current screen display content Type determines the first pace of change of the current screen content；Then the speed of service of the application is obtained again, in the first change speed On the basis of degree, corresponding speed adjustment is carried out in conjunction with the ruuning situation that applies belonging to current screen display content, to obtain second Pace of change；Wherein, pace of change is proportionate with the speed of service, i.e., the speed of service is slower, and pace of change is less, accordingly, The speed of service is faster, and pace of change is faster.Certainly, the pace of change of current screen content periodically can determine, it is also possible to real When determine.In the present embodiment, for corresponding one first pace of change in the display content of a certain application type application；Namely Say, when the corresponding application of the current screen content belongs to first kind application, the acquisition first kind application can be corresponded to Corresponding first pace of change, using first pace of change as current screen content the first pace of change.In such manner, it is possible to When making initially to gather on-screen data, quick determination preferably screen capture speed, and then obtain preferably on-screen data.Wherein, The ruuning situation of connected applications determines the second pace of change of current screen content, can work as in conjunction with the follow-up of practical situation adaptability The pace of change of forth screen, is to determine that more accurately screen capture speed provides effective support.

Further, when the first terminal adjusts screen capture frequency according to the display content pace of change of current screen Afterwards, based on the screen capture frequency collection on-screen data after adjustment.Such as, the pace of change of video class application is very fast, manuscript The pace of change of demonstration class application is slower；In concrete practice, screen capture frequency is adjusted according to the situation of change of inhomogeneity application Rate.

Using the technical scheme of the embodiment of the present invention, by the focus function of the first mobile terminal, the second mobile terminal is made Wireless connection and data transfer that the first address just can achieve the first mobile terminal and the second mobile terminal need to be only obtained, is realized The compatibility of the full platform of shadow casting technique, expands the range of user；On the other hand, projection side is according to current screen content Pace of change adjustment screen capture frequency, and then according to the screen capture speed gather on-screen data, transmission can be saved Resource, reduces the energy consumption of projection end and receiving terminal；It also avoid not catching up with the change of screen display content because of fixing frequency acquisition Change speed and cause receiving terminal leakage to show the phenomenon of part of screen data, be conducive to lifting the experience of user.
