Abstract
There is provided a video output apparatus which inputs a video content that can have at least three different resolutions. A format detector detects an alteration of a resolution of a video content. A scaling processor scales up the video content at a set scale ratio. Upon detection of an alteration of the resolution, the format detector selects one of a plurality of supplemental video pictures, which are prepared in advance in a memory, in accordance with the degree of decrease of the resolution after the alteration to that before the alteration. An image composition unit controls a display unit to display the supplemental video picture together with a video associated with the video content via a video display unit.
