Method of establishing paid connection using screen mirroring application between multi-platforms

A method of establishing a paid connection between multi-platforms, where a transmitting end application is installed in a transmitting end apparatus of a sharing source and a receiving end application is installed in a receiving end apparatus of a sharing target. When establishing a connection, the transmitting end application/receiving end application confirms whether a unique ID of the receiving end apparatus/transmitting end apparatus exists in an exception list, and confirms whether the receiving end application/transmitting end apparatus makes payment based on an operating system used by the transmitting end apparatus/receiving end application, in order to determine establishing a limited or an unlimited connection between the transmitting end apparatus and the receiving end apparatus. Thus, the method assures that either the transmitting end application or the receiving end application is a paid version, a user complies with an application license agreement by using the exception list and the right of application developers is protected.
