KR970078495A - Television receiver with automatic caption on mute - Google Patents

Abstract

In particular, the present invention relates to a television receiver equipped with an action function, and more particularly, to a method of automatically setting a caption function during a mute operation for temporarily stopping audio output, The present invention relates to a television receiver equipped with an automatic caption function for controlling the position of an OSD. When a mute signal is input from a user, the audio signal output from the audio processing unit is cut off and a caption decoder is driven, G, and B signals for generating a corresponding on-screen display (OSD) according to the control of the control unit, and outputs R, G, and B signals to the image processing unit R, G, and B output from the image processing unit and R, G, and B output from the OSD generating unit, respectively, for outputting a blanking signal Y ' A first OSD memory for storing position information on a CRT for displaying a normal OSD, a mixer for mixing R, G, and B signals for mixing the Y 'signals and displaying them on the CRT, And a second OSD memory for storing OSD position information on the CRT so as not to overlap the caption subtitle when the subtitle is output.
