Find android screen sharing solution developed

Android screen sharing, screen broadcast, screen synchronization, remote monitoring < / a>

I android newbie, recently encountered a problem: how to screen an android device real-time sharing to multiple devices. I'm not sure what this technique is called, screen sharing, screen synchronization, screen broadcasting, remote monitoring? These are not a mean?

Are there principles to achieve screen sharing function on android and solutions, and on the PC the same?

Great God explain seeking concrete solutions! Trouble is, say what you want to achieve this function module need to use what technology, such as screen capture, compression algorithms, what transmission protocol.

Someone said that to achieve the android screen sharing and screen sharing on the computer to achieve the same, but the screen is cut, compress, send, receive, extract, process display.
But some say this is inefficient and can not guarantee real-time transmission.
Some people say that is what hardware to use the programming? ? Dizzy, seeking advice!<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->
