Abstract

For a BD-ROM, a picture-in-picture function and a wallpaper display function are accomplished. A second video plane 50 for displaying a moving picture is added to planes 10, 11, and 12 for displaying a moving picture, a subtitle, and graphics, respectively. One of the outputs of the second video plane 50 and the video plane 10 is selected by a switch 51 on a pixel-by-pixel basis. Reduced moving picture data are stored on the second video plane 50. The switch 51 is controlled according to a display position of the reduced moving picture data on a pixel-by-pixel basis. As a result, reduced moving picture data of the second video plane 50 are displayed as a sub screen against the moving picture data of the video plane 10. When wallpaper picture data instead of the moving picture data are stored on the video plane 10, a display screen is obtained as if a wallpaper were displayed in the background of the reduced moving picture data.

Claims

1. A reproduction apparatus, comprising:

first storage means for storing first moving picture data reproduced from a record medium;

second storage means for storing second moving picture data reproduced from the record medium; and

selection means for selecting one of outputs of the first storage means and the second storage means on a predetermined area-by-area basis,

wherein a display signal is generated based on the output of the selection means.

2. The reproduction apparatus as set forth in claim 1,

wherein the predetermined area is a pixel.

3. The reproduction apparatus as set forth in claim 1,

wherein the first storage means and the second storage means are plane memories.

4. The reproduction apparatus as set forth in claim 3,

wherein one of the first storage means and the second storage means stores reduced moving picture data of which the moving picture data have been reduced corresponding to a display position thereof, and

wherein the selection means selects one of the outputs of the first storage means and the second storage means corresponding to the display position of the reduced moving picture data.

5. The reproduction apparatus as set forth in claim 4,

wherein the other of the first storage means and the second storage means stores wallpaper picture data instead of the moving picture data.

6. The reproduction apparatus as set forth in claim 3, further comprising:

first combining means for combining the output of the selection means and subtitle data reproduced form the record medium; and

second combining means for combining the output of the first combining means and video data reproduced from the record medium.

7. The reproduction apparatus as set forth in claim 6,

wherein the combination ratio of the first combination means is controlled based on the subtitle data.

8. The reproduction apparatus as set forth in claim 6,

wherein the combination ratio of the second combination means is controlled based on the video data.

9. The reproduction apparatus as set forth in claim 1,

wherein the first storage means and the second storage means are frame memories, and

wherein the output of the selection means is supplied to a plane memory.

10. The reproduction apparatus as set forth in claim 9,

wherein the selection means selects reduced moving picture data of which moving picture data that have been output from the first storage means or the second storage means have been reduced corresponding to a display position of the reduced moving picture data and supplies the reduced moving picture data to the plane memory.

11. The reproduction apparatus as set forth in claim 10, further comprising:

first combination means for combining an output of the plane memory and subtitle data reproduced from the record medium; and

second combination means for combining an output of the first combination means and video data reproduced from the record medium.

12. The reproduction apparatus as set forth in claim 11,

wherein the combination ratio of the first combination means is controlled based on the subtitle data.

13. The reproduction apparatus as set forth in claim 11,

wherein the combination ratio of the second combination means is controlled based on the video data.

14. The reproduction apparatus as set forth in claim 11,

wherein a transparent area in which the output of the first combination means is displayed with the video data that are combined with the output of the first combination means by the second combination means is placed corresponding to the display position of the reduced moving picture data.

15. The reproduction apparatus as set forth in claim 14,

wherein a wallpaper picture is displayed in the other than the transparent area of the video data.

16. The reproduction apparatus as set forth in claim 15,

wherein a picture of a part is also displayed with the output of the second combination means, and

wherein the wallpaper picture is displayed in other than the transparent area and the display area of the picture of the part.

17. A reproduction method, comprising the steps of:

storing first moving picture data reproduced from a record medium to first storage means;

storing second moving picture data reproduced form the record medium to second storage means; and

selecting one of outputs of the first storage means and the second storage means on a predetermined area-by-area basis,

wherein a display signal is generated based on an output of the selection step.

18. A reproduction program that causes a computer device to execute a reproduction method, comprising the steps of:

storing first moving picture data reproduced from a record medium to first storage means;

storing second moving picture data reproduced form the record medium to second storage means; and

selecting one of outputs of the first storage means and the second storage means on a predetermined area-by-area basis,

wherein a display signal is generated based on an output of the selection step.

19. A computer readable record medium on which a reproduction program has been recorded, the reproduction program causing a computer device to execute a reproduction method, comprising the steps of:

storing first moving picture data reproduced from a record medium to first storage means;

storing second moving picture data reproduced form the record medium to second storage means; and

selecting one of outputs of the first storage means and the second storage means on a predetermined area-by-area basis,

wherein a display signal is generated based on an output of the selection step.
