Abstract
A video display apparatus having user-selected hotkey functions and a method of using them is disclosed in which a function of the video display system can be changed by a user. Information on a menu item is selected by a user from an OSD menu which the video display apparatus has stored in a memory unit as hotkey button information. The information is read from the memory unit to be executed whenever the user selects a given hotkey button. The hotkey button information may be re-set according to the user's desires, so that the user controls the functions of the video display apparatus with more ease and convenience.
Claims10
A video display control apparatus having hotkeys for a user to invoke and control a function of a video display apparatus, said function represented by a menu item from an on-screen display (OSD) menu, said video display control apparatus comprising:
- a button unit comprising a hotkey button adapted for generating a key signal corresponding to a menu item of an OSD menu;
- a memory unit coupled to the button unit, and adapted for storing information concerning OSD menu items;
- an OSD unit for outputting an OSD character display signal to a video processing unit in response to said key signal, whereby actuation by a user of said hotkey button causes a screen display of one or more OSD characters;
- and
- a control unit for receiving said key signal from said button unit, for reading information concerning an OSD menu item stored in the memory unit when said key signal is received, and for thereupon sending a control signal to the video display apparatus to control a function thereof.
A method of controlling a function of a video display apparatus, said method comprising the steps of:
- (1) when a user selects a menu item of an on-screen display (OSD) menu screen by causing generation of a hotkey button signal, determining whether a hotkey signal setting exists therefor;
- (2) when no hotkey signal setting exists therefor, executing a control function in response to the hotkey button signal;
- and
- (3) when a hotkey signal setting exists therefor, setting the user-selected menu item of the OSD menu screen responsively to the hotkey button signal.
A method of controlling a function of a video display apparatus, said method comprising the steps of:
- (1) when a user selects a hotkey button, thereby generating a present-time hotkey button signal, determining whether a stored hotkey button signal identical to the present-time hotkey button signal is stored in a memory unit;
- (2) if a stored hotkey button signal is identical to the present-time hotkey button signal, executing a control function in response to the stored hotkey button signal;
- and
- (3) if no stored hotkey button signal is identical to the present-time hotkey button signal, executing a default control function.
A television (TV) system, comprising:
- a TV display having a plurality of functions, said TV display being capable of displaying an on-screen display (OSD) menu having a plurality of menu items respectively corresponding to individual ones of said plurality of functions;
- a memory unit adapted for storing information concerning OSD menu items;
- means operable by a user for selecting one of said plurality of menu items;
- means for generating a selection signal corresponding to said one of said plurality of menu items in response to selection thereof by the user;
- control means for controlling said plurality of functions;
- receiving means associated with the TV display for receiving said selection signal;
- reading means coupled to said receiving means for fetching and reading, from the memory unit, information concerning an OSD menu item stored in the memory unit when said selection signal is received, said information corresponding to said selection signal;
- and
- sending means coupled to said reading means for sending a control signal to said control means, said control signal corresponding to said fetched and read information concerning the OSD menu item, whereby a function of the TV display is controlled in response to the control signal and in response to said information fetched and read from the memory unit concerning the OSD menu item.
