Method and apparatus for controlling a video signal processing apparatus to prevent screen aging
First Claim
1. A method for controlling a video display, comprising the steps of:
- receiving a program signal from a signal source;
enabling display of a video program corresponding to the received program signal on a display device, wherein the video program is displayed with a display parameter at a first level;
activating a browser feature of the video display apparatus in response to a first user input;
enabling display of a browser on the display device in response to the activation of the browser feature, wherein the browser is displayed with the display parameter at a second level different from the first level, and the display parameter is automatically switched from the first level to the second level in response to the activation of the browser feature.

Abstract
An apparatus and method for controlling a video signal processing apparatus having a browser feature to protect a display device associated with the apparatus against the premature aging effects of screen burn due to an idle display when the browser feature is activated. The method includes the steps of detecting a first user input to a video apparatus, determining whether the first user input activates a browser feature of the video apparatus, and controlling the operation of the apparatus to reduce the screen burn. The operation can include setting a display parameter for the video apparatus to a first predetermined level responsive to determining that the first user input activates the browser feature, or determining an idle time and inactivating the browser feature if the idle time exceeds a predetermined period of time.

19. A video apparatus, comprising:
-
an input for receiving a plurality of program signals; and a processor, coupled to the input, for processing the received program signals and enabling display of video programs corresponding to the received program signals on a display device, the processor causing the video programs to be displayed with a display parameter set to a first level, the processor enabling display of a browser on the display device in response to user activation of a browser feature, wherein the processor causes the browser to be displayed with the display parameter set to a second level and causes the display parameter to be automatically switched from the first level to the second level in response to the user activation of the browser feature.
