    摘要: 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.
