Description
Technical field
The present invention relates to throw screen field, and in particular to a kind of throwings screen control method throws screen control terminal and throwing screen system.
Background technique
With the development of internet technology, it throws screen technology to be widely used, throwing screen refers to will be in an equipment
It is played out in media file dispensing to another equipment, throws screen and is also multi-screen interactive, for example, the video dispensing on mobile phone is arrived
It is played out on smart television, such user can browse the video on mobile phone on smart television.Current multi-screen interactive side
Case is all that communication is directly established in transmitting terminal and receiving end, it is therefore necessary to which transmitting terminal and receiving end are connected to the same Wifi network
It is just able to achieve and identifies each other, for some occasions, such as hotel, will there is the case where multiple receiving ends share a Wifi,
If user A moves in the room of the hotel the 1st and carried out throwing screen, the hotel is moved in but what is moved in is the hotel when user A is secondary again
No. 2 room when, client A also thinks to carry out throwing screen again, if the throwing screen software for the transmitting terminal that client A is held have memory function, hair
Sending end once opens screen projection function, it is easy to the case where transmitting terminal is connected to garbled-reception end (receiving end in No. 1 room) occurs, no
Other people are only seriously affected, bad experience is also brought to user oneself；It on the other hand, may if the intentional practical joke of user A
There is the case where deliberately launching media file to other receiving ends for connecting upper identical Wifi network.
