Display signal control apparatus, and display signal control method

Abstract

The present invention displays a broadcast program without causing discomfort to the viewer caused by a shift in the display position. The burn-in of the display apparatus when displaying EPG and GUI images is prevented. When viewing a channel, the timing of events such as the broadcast start time of the next program and the insertion of CM video are acquired from program attribute information such as the SI and metadata. Information such as the time of the next program or insertion of an advert is detected from the attribute information, and video data that is displayed in the display area of the display unit is changed at that time. The change in video data is executed when setting the area of the video data to be applied to the effective video data area to the display area, by changing the coordinate data of this area.
