摘要： A method of establishing a charged connection using a screen sharing application between multi-platforms is disclosed. A transmitting end application is installed in a transmitting end apparatus of a sharing source. A receiving end application is installed in a receiving end apparatus of a sharing target. If the transmitting end application is a charged version, an unlimited connection is established for performing screen sharing between the transmitting end apparatus and any receiving end apparatus. If the transmitting end application is a free version, the method further confirms if the receiving end application is a charged version for deciding whether a limited connection or an unlimited connection should be established. Thus, it is assured that either the transmitting end application or the receiving end application is a charged version, the interests of application developers are protected and users are free from paying twice for establishing one connection.
