Abstract:
1. A method for moving a cursor in a display apparatus, comprising: displaying a plurality of first-tier sub-regions on a screen of the display apparatus in response to a first control command, wherein the screen has a screen resolution; displaying a plurality of first Arabic numeral reference symbols respectively within the plurality of first-tier sub-regions, such that each one of the plurality of first-tier sub regions corresponds to a particular one of the first Arabic numeral reference symbols; selecting one of the first-tier sub-regions in response to a second control command; moving the cursor to the selected first-tier sub-region with a first coordinate based on the screen resolution; receiving an image signal with an image resolution from an external host and displaying the image signal on the screen with the screen resolution; generating a second coordinate in the image resolution by transforming the first coordinate in the screen resolution; sending the second coordinate to the external host; moving the cursor according to the second coordinate; and dividing the selected first-tier sub-region into a plurality of second-tier sub-regions; wherein actuation of a predetermined button on a remote controller of the display apparatus three consecutive times causes the display apparatus to enter a cursor control mode.
