[0017]
The cursor key 17 moves the cursor displayed on the display, selects an item designated by the cursor, and the like. The numeric key 18 is used to input a numeric value and select an item number displayed on the display. It should be noted that a group corresponding to the numerical key 18 is selected by operating the numerical key 18 following the group key 16.
[0018]
FIG. 3 is a conceptual diagram showing an example of a recording state of video data recorded on a disc. In the video data, frame data indicating one screen is continuous, and each scene is composed of a plurality of frames. Each scene is grouped according to contents, and group information for each scene is recorded in the top area of the disc. A chapter for dividing the video content recorded on the disc may be provided for each grouped scene, or a plurality of scenes grouped in one chapter may be provided.
[0019]
FIG. 4 shows a table of group information recorded on the disc. For each scene, along with the group information consisting of the corresponding group number and content of each group is recorded, a representative picture information consisting of the frame number of the representative screen F in the scene (see FIG. 3) is recorded. For example, each scene of the video data is classified into a group consisting of “joy”, “anger”, “sorrow”, and “easy”. The first scene is composed of the first frame to the fourth frame, and is classified into group 1 (a group of “joy”). The representative screen of the first scene is the second frame.
[0020]
Each scene may be grouped according to contents different from the above. For example, a group consisting of a violent scene, a group consisting of an appearance scene of a specific character, a group consisting of a music scene, and the like can be provided.
[0021]
In the disc reproducing apparatus 1 having the above configuration, when a disc is loaded, the disc is loaded at a predetermined position where a signal can be read, and the operation shown in the flowchart of FIG. 5 is performed. In step # 11, it is determined whether or not a reproduction instruction has been issued by operating the image operation key 14.
[0022]
If there is no instruction for reproduction, the process proceeds to step # 12, and it is determined whether or not a group has been designated by operating the group key 16 and the numeric key 18 of the remote controller 10. If no group is designated, it is determined in step # 13 whether or not the menu key 15 of the remote controller 10 has been operated. If the menu key 15 is not operated, the process returns to step # 11, and steps # 11 to # 13 are repeated to enter a standby state.
[0023]
If there is an instruction for reproduction from the standby state, the process proceeds to step # 30 based on the determination in step # 11, where reproduction is started from the beginning of the disc, and the process ends. If a group is designated from the standby state, the process proceeds to step # 19, which will be described later, based on the determination in step # 12. If the menu key 15 is operated from the standby state, the process proceeds to step # 14 based on the determination in step # 13.
[0024]
In step # 14, a list of menu items is displayed on the display screen. In step # 15, the operation waits until a menu item is selected by operating the cursor key 17 or the numeric key 18. When a menu item is selected, it is determined in step # 16 whether or not a group list display menu has been selected. If the selected menu item is not a group list display, the process proceeds to step # 31, and a process corresponding to the selected menu is called.
[0025]
When the group list display is selected, as shown in FIG. 6, the groups included in the disc are displayed as a list, and the group number and the contents of the scene included in the group are displayed. In step # 18, the process waits until a group is selected by moving the cursor C with the cursor key 17 or selecting an item with the numeric key 18. When a group is selected, the process proceeds to step # 19, and as shown in FIG. 7, for example, the representative screen F of each scene included in the group 2 is displayed as a list.
[0026]
In steps # 20 and # 21, the process waits until a return operation or a reproduction operation is performed. If it is not desired to reproduce the group displayed by the list on the representative screen, a return operation is performed to return to step # 17. As a result, another group can be selected. When the reproduction operation is performed, the process proceeds to step # 22 and the group on which the representative screen is displayed is reproduced. Note that the return operation and the reproduction operation can be performed by, for example, the “←” key and the “→” key of the cursor key 17, respectively.
