Abstract: A method for swapping display contents between a first and a second screen. The first screen is a primary screen. A window is displayed on one of the first and the second screen. The method includes: calculating a window movement distance according to a relative position between the first and the second screen; performing swapping to set the second screen as the primary screen; obtaining a coordinate of the window after swapping; obtaining a first coordinate by adding the window movement distance to the coordinate of the window after swapping if the window is located in the first screen before swapping; obtaining a second coordinate by subtracting the window movement distance from the coordinate of the window after swapping if the window is located in the second screen before swapping; moving the window from one of the first and the second screen to the other.

Abstract: The present invention relates to a method for assisting an application, executed in a processing platform where a first operation system is installed, in controlling a USB device plugged in a second operation system rather than the first operation system. First, under the first operation system, the method is used for receiving a USB request block in a first format, translating the USB request block in the first format into the USB request block in a second format native to the second operation system in accordance with an algorithm, and transmitting the USB request block in the second format out. Next, under the second operation system, the method is used for controlling the USB device in accordance with the USB request block in the second format.

Abstract: A video apparatus including a processing unit, a tuner, a video processor, a network unit and an information-converting module is provided. The tuner receives a video signal. The information-converting module includes a download module, an analysis module and a graphics module. The download module downloads a web page with internet content from the web page server through the network unit. The analysis module analyzes the web page to obtain the internet content. The graphic module converts the internet content into a graphic data. The video processor can combine the graphic data with the video signal and output a combination signal. A signal processing method of the video apparatus is provided also.
