Publication number: 20140012999Abstract: A method of establishing a paid connection using a screen mirroring 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 paid version, an unlimited connection is established for performing screen mirroring 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 paid 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 paid version, the interests of application developers are protected and users are free from paying twice for establishing one connection.Type: ApplicationFiled: September 10, 2013Publication date: January 9, 2014Applicant: Awind Inc.Inventors: Kuo-Lung CHANG, Hsing-Yung WANG, Meng-Chung HUNG, Kuan-Yu CHOU, Chin-Jung FAN, Shih-Pin LIU, Li-Ger CHEN

Publication number: 20130294498Abstract: A video encoding system applied in a remote desktop system includes a capturing module, an encoding module and an estimating module. The capturing module is configured for capturing a plurality of screen frames of an electronic device at a capture rate. The encoding module is configured for encoding the screen frames captured by the capturing module at an encoding rate. The estimating module is configured for determining whether the current screen frame changes or not and then adjusting the encoding rate of the encoding module according to the estimating result. In this case, the encoding rate is equal to or less than the capture rate. The video encoding system can reduce system resource usage and energy consumption when the screen frame does not change. A video encoding method and a computer readable medium storing the method are also disclosed.Type: ApplicationFiled: April 23, 2013Publication date: November 7, 2013Applicant: Awind, IncInventors: Kuo-Lung CHANG, Hsing-Yung WANG, Way LU-CHEN, Kuan-Yu CHOU, Meng-Chung HUNG
