Patent attributes
A TV system including an optical disc apparatus capable of preventing a burn-in from appearing on the screen of a display is provided, wherein a timer is started to transmit still image data from the optical disc apparatus to a TV image receiver. When a predetermined time elapsed after a still image is displayed, a CPU in the optical disc apparatus sends information of the elapsed time to a CPU in the TV image receiver. Then, the latter CPU saves the current brightness value stored in a memory and supplies a brightness value smaller than the current brightness value to a drive unit for the display, thereby enabling the image intensity to be reduced on the display and/or an OSD image to be eliminated in the still image. The image intensity on the display can be returned to the initial intensity and/or the eliminated OSD image can be recovered by pushing appropriate selection keys in an operation section.
