Abstract: A method for switching mobile television channels of a mobile computing device includes the following steps: First, an original channel is played on a screen of the mobile computing device. A first channel number of a first selected channel is received at a first time point. Then, a second channel number of a second selected channel is received at a second time point, wherein a time interval between the first and second time points is less than a predetermined interval for action. A period of time from the second time point to an action time point is counted, wherein the period of time is equal to the predetermined time interval for action. Next, data bursts of the second selected channel are received and buffered from the action time point to a next time point. At last, the second selected channel is played on the screen from the next time point.

Abstract: A method for gradually adjusting screen brightness when switching an operating system is provided. The method is used for gradually adjusting the brightness of a screen of an electronic device by a controller thereof when the electronic device is switched from a first operating system to a second operating system. First, an operating system switching signal is received. Then, a first brightness value of the first operating system is obtained. The screen brightness is gradually adjusted from the first brightness value to a predetermined second brightness value. Afterwards, the first operating system is switched to the second operating system, and the screen brightness is further adjusted from the second brightness value back to the first brightness value. Accordingly, a user can sense the switching of the operating system more intuitively and has enough time to get used to the change of the screen brightness and the displayed frame.

Abstract: A system and an electronic device having multiple operating systems and an operating method thereof are provided. The electronic device includes a display and a system having a first operating system, a second operating system, and an embedded controller.
