Abstract: PURPOSE: To eliminate troubles that sound signal is not in matching with a video image by supplying automatically sound signal of a video image to a main screen when a multi-pattern video signal is displayed as a sub-image screen. CONSTITUTION: A control section 9 detects the mode that a character broadcast signal is displayed as a sub-pattern, and gives a control signal to a changeover section 13 to select sound signal of a main screen. That is, the mode is transited to mode displaying characters of a character broadcast on a sub-screen and the characters of the character broadcast are displayed on the sub-screen to discriminate whether the sound signal is a signal for the main screen or the sub-screen. When the sound signal of the sub-screen in outputted, since a sound signal independently of the video image of the main screen is outputted, a control signal is fed to the changeover section 13 to allow it to select the sound signal (position of SIF 1) of the main screen. Furthermore, when the sound signal (position of SIF 1) of the main screen is outputted, the sound signal is not switched.
