Patent ID: 8204357

Claim:
A reproduction apparatus for reproducing content data comprising: a reproducing unit configured to reproduce the content data from a recording medium; a determining unit configured to determine whether the content data being currently reproduced from the recording medium includes one of a first moving picture, a second moving picture, presentation graphics data, and interactive graphics data, and provides the content data being currently reproduced to one of a first plane memory, a second plane memory, a third plane memory, and a fourth plane memory based on the determination; the first plane memory configured to store the first moving picture data reproduced from the recording medium; the second plane memory configured to store the second moving picture data reproduced from the recording medium; a selection means for selecting at least one of an output of the first plane memory and the second plane memory on a pixel-by-pixel basis; a first scaling unit configured to change a size of the first moving picture output from the first plane memory; a second scaling unit configured to change a size of the second moving picture output from the second plane memory; the third plane memory configured to store the presentation graphics data reproduced from the recording medium; the fourth plane memory configured to store the interactive graphics data reproduced from the recording medium; a first blending unit configured to modify an opacity of an output from the selection means based on a first predetermined opacity value; a second blending unit configured to modify an opacity of the presentation graphics data stored in the third plane memory based on the first predetermined opacity value; a first combining means for adding an output from the first blending unit and the second blending unit; a third blending unit configured to modify an opacity of an output from the first combining means based on a second predetermined opacity value; a fourth blending unit configured to modify an opacity of the interactive graphics data stored in the fourth plane memory based on the second predetermined opacity value; and a second combining means for adding an output from the third blending unit and the fourth blending unit, wherein the selection means selects corresponding to an intended display position of a reduced size moving picture, and a display signal is generated based on the output of the selection means, and wherein the first plane memory is a bottommost plane arranged before the second plane memory, the second plane memory is arranged between the first plane memory and the third plane memory, the third plane memory is arranged between the second plane memory and the fourth plane memory, and the fourth plane memory is a topmost plane.
