Abstract: 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.

Abstract: A mirroring transmission method is provided. The present method retrieves image frames and audio signals of a transmitter and transmits the retrieved image frames and retrieved audio signals to a receiver to be displayed wirelessly. In the meantime, the present method monitors status of a network connected with the transmitter and the receiver, and determines if the network is stable or not. Also, the method stops retrieving and transmitting the audio signal from the transmitter to the receiver, and controls the transmitter to display the audio signal directly through an internal audio module whenever the network is determined unstable.

Abstract: A mirror display system having low data traffic comprises a transmitting-end device and a receiving-end device. The transmitting-end device stores a first file and transforms the first file into the first page images. The receiving-end device stores a second file with same content of the first file and transforms the second file into the second page images. The transmitting-end device selects one of the first page images according to a page-selecting operation, and transmits an identifying page data of the selected first page image to the receiving-end device. The receiving-end device selects and displays one of the second page images corresponding to the identifying page data. With pre-storing the file duplicate in the receiving-end device and the receiving-end automatically generating the image, the required data traffic of the mirror display is effectively reduced and the mirror display operation is made smoother.
