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.

摘要： An encoding method of screen frame and its application of electronic devices, which rapidly detect motion regions and motionless regions from lossless screen frames captured by software, and then encode the motion regions with lower image quality while encode motionless regions with higher quality to display higher quality images and smooth video at a receiving end in real-time. Furthermore, the above-mentioned encoding method is optimized for lossless screen frames which does not need complicated operations of video encoder of prior art, such as motion estimation, motion compensation, etc., so that the method can be implemented with minor system resources and lower latency delay.

摘要： A file management system is used in a peer-to-peer file-share mechanism. The file management system is used for managing at least one file transmitted between at least one data terminal and at least one abstracting terminal via networking. The data terminal stores the file and a searching data corresponding to the file. The searching data comprises a characteristic data of the file and a location of the file. After the characteristic data is chosen at the abstracting terminal, the abstracting terminal traces the location via networking, couples to the data terminal, and further abstracts the file corresponding to the characteristic data. The data terminal uses an encryption module to encrypt the file to an encryption file. A software package is used for conveniently transmitting the file to the abstracting terminal. Thus, the software package can decrypt the encryption file to the file for a user subsequently to use at the abstracting terminal.
