  FIG. 8 is a diagram illustrating an example of the display screen 102a on which the three-dimensional image 610, the two-dimensional image 620, and the scroll bar 623 are displayed.

  In the present embodiment, one year is divided into four reference periods of January to March, April to June, July to September, and October to December. In the two-dimensional image 620, only a region representing one of the reference periods is displayed. In the following, the programs distributed at the same time on the same day of the week are given the same number, and the week in which each program is distributed is distinguished by the number added at the end.

  In the three-dimensional image 610 shown in FIG. 8, in the initial state, a list of programs that are distributed and recorded from 7 o'clock to 23 o'clock, in which programs are generally recorded, is displayed. By moving the three-dimensional scroll bar 602 using 601, a list of programs distributed and recorded from 0:00 to 6:00 can be displayed. In addition, thumbnail images 612_1, 613_1, and 614_1 of programs distributed at the same time on a fixed day of the week are displayed in a straight line along the X axis (day of the week) and distributed every week at the same time on the same day of the week. Thumbnail images 611_1, 611_2, 611_3, 611_4, and 611_5 of the displayed programs are displayed in a straight line along the Z axis.

  As described above, according to the recording / playback apparatus 500 of the present embodiment, the thumbnail images of the programs distributed at the same time are arranged on the same line in the three-dimensional image 610, and therefore these programs are distributed every week on the same day of the week. It is possible to visually confirm that the program is a related program such as a series drama or news distributed at the same time.

  In the two-dimensional image 620 shown in FIG. 8, the mark 621 is located at a position corresponding to the position where each thumbnail image is arranged on the three-dimensional image 610 in the two-dimensional space where the X axis is the day of the week and the Y axis is the week. Is displayed. A mark 621 indicates that there is a program recorded on that day. When there is a program recorded on the same day of the week, the mark 621 is displayed side by side along the Y axis (in the week direction).
