Abstract:
1. A method of preventing a browser from refreshing when receiving responses to commands sent to an apparatus being controlled by the browser via a network, said browser displaying a remote control for controlling the apparatus, the method comprising the steps of: displaying on said browser a child frame containing the remote control and a dummy frame comprising substantially zero-percent of the browser, said child frame including an update frame containing a portion of the remote control that requires updating; dividing the update frame into four rectangular frames to surround a changing frame of the update frame, said four rectangular frames forming the update frame when combined together, wherein each of the four frames abut the changing frame on a respective top side, left side, right side, and bottom side of the changing frame; issuing a first command to the apparatus using the displayed remote control, said first command not changing the displayed remote control; issuing a second command to the apparatus using the displayed remote control, said second command changing the portion of the remote control that required updating; receiving a first response to said first command from said apparatus into said dummy frame, said first response re-drawing the dummy frame; receiving a second response to said second command from said apparatus and updating only the update frame that contains the portion of the remote control that requires updating, wherein the entire child frame does not refresh, and only the changing frame of the update frame is refreshed; and standardizing background color of only the update frame to a surface color upon detection of a time difference between the first response and second response.
