Patent ID: 8817187

Claim:
A digital broadcast receiving apparatus that receives digital broadcasting to display an image on a screen of a display device, comprising: a first image generator that generates first video data for displaying an image for an application program as a first image on said screen; a second image generator that generates second video data for displaying a graphic image as a second image on said screen; a storage that stores the first video data generated by said first image generator at predetermined timing; a synthesizer that synthesizes the first video data and the second video data to display the first and second images on said screen; a controller that selectively switches a display state on said screen between a first display state where the first image is displayed and a second display state where the first and second images are displayed; and a size changer that processes the first video data generated by said first image generator to change at least one of vertical and horizontal dimensions of the first image, wherein the second image in said second display state includes a display frame for displaying said first image, the display frame having a shape different from a shape of said screen and having a non-rectangular shape, said controller controls said first image generator so that the first image based on the first video data generated by said first image generator is displayed on said screen in said first display state, and controls said second image generator, said storage, and said synthesizer so that the second image based on the second video data generated by said second image generator is displayed on said screen while the first image based on the first video data stored in said storage is displayed in said display frame in said second display state, and said controller controls said second image generator so that the second image is displayed on said screen in said second display state, controls said size changer so that the vertical and horizontal dimensions of the first image are respectively changed to the maximum lengths in a vertical direction and a horizontal direction of said display frame, and a portion of the changed first image corresponding to an area outside the display frame is deleted, and controls said synthesizer so that a portion corresponding to an area, in said display frame, of the first image changed by the size changer is displayed in said display frame.
