In addition, when the list generation unit 204 acquires a remote control signal for selecting any of the thumbnail images included in the thumbnail list image superimposed on the recording list via the infrared light receiving unit 40, the list generation unit 204 displays a thumbnail image indicated by the acquired remote control signal. The playback unit 205 is notified.

  In the present embodiment, the list generation unit 204 has been described by way of example of a configuration in which the thumbnail list image is superimposed on the recording list. However, a configuration in which all or part of the thumbnail image is directly superimposed on the recording list is employed. May be.

(Playback part)
The playback unit 205 plays back the recorded program. Specifically, the playback unit 205 reads a recorded program from the broadcast program storage unit 301 of the memory 30 and outputs the read recorded program via the communication unit 50. Note that the recorded program played back by the playback unit 205 may be directly selected, for example, by the user operating the remote control, or is recorded on the recording list generated by the list generation unit 204 or superimposed on the recording list It may be selected from thumbnail list images.

  Also, the playback unit 205 superimposes the thumbnail list image supplied from the thumbnail list image generation unit 203 on the recorded program being played back. Specifically, when the playback unit 205 acquires a remote control signal for superimposing the thumbnail list image on the recorded program being played back via the infrared light receiver 40, the playback unit 205 adds the recorded program being played back to the recorded program being played back. Superimpose thumbnail list images.

  At this time, the reproduction unit 205 emphasizes a thumbnail image corresponding to a period during which the recorded program is being reproduced (a period to which the reproduction position belongs) among thumbnail images included in the thumbnail list image superimposed on the recorded program being reproduced. May be.

  The playback unit 205 superimposes the thumbnail list image on the recorded program being played back, and outputs it via the communication unit 50.

  In addition, when any one of the thumbnail images included in the thumbnail list image superimposed on the recorded program being reproduced is selected by a user's remote control operation, the reproduction unit 205 starts from a period corresponding to the selected thumbnail image. Resume playback of the recorded program.

  In the present embodiment, the playback unit 205 has been described as an example of a configuration in which the thumbnail list image is superimposed on the recorded program being played back. However, all or part of the thumbnail images are directly superimposed on the recorded program being played back. You may employ | adopt the structure to do.

[Display screen]
Next, an example of a recording list output from the recorder 1 according to the present embodiment and a display screen showing a recorded program to be reproduced will be described with reference to FIGS. Note that the recording list output from the recorder 1 and the display screen showing the recorded program to be played back are presented to the user by being displayed on an external display device (not shown) connected to the communication unit 50. It only has to be done.

(Recording list)
First, an example of a display image (also referred to as a recording list) indicating a recording list generated by the list generation unit 204 included in the control unit 20 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a recording list generated by the list generation unit 204 according to the present embodiment.

  As shown in FIG. 2, in the recording list, the titles of recorded programs stored in the broadcast program storage unit 301 are displayed in a listable manner. In the recording list shown in FIG. 2, the titles of 18 recorded programs are listed, but the number of titles displayed in a list is not limited to this.

  When 19 or more recorded programs are stored in the broadcast program storage unit 301, the list generation unit 204 moves the recording list from the top to the end of the list (in the direction from title 1 to title 18 in FIG. 2). By scrolling to, a recording list may be generated in which the titles of recorded programs that have not been displayed in a list are newly displayed.

  In addition, the list generation unit 204 displays a plurality of recording lists such as a first recording list of titles 1 to 18, a second recording list of titles 2 to 19, and a third recording list of titles 3 to 20. It may be generated. In this case, each time the recording list is scrolled from the top to the end of the list, the recording list output from the recorder 1 is the first recording list, the second recording list, and the third recording list. It is sufficient to switch sequentially.

  Further, as shown by an arrow A in FIG. 2, one title among the titles included in the recording list is highlighted (focused) and displayed (highlighted). The highlighted title may be switched by the user operating a cross key, jog dial, or the like (both not shown) of the remote controller. Note that the highlighting of the titles included in the recording list may be performed by, for example, highlighting the emphasized title or making the frame surrounding the emphasized title thick, but it is not particularly limited. Absent.

(Recording list with thumbnail list images superimposed)
As shown in FIG. 2, for example, when “Title 6” is highlighted, when receiving a remote control signal by a user operation to select a recorded program of “Title 6”, the list generation unit 204 The thumbnail list image of the recorded program is superimposed on the recording list.

  An example of a recording list on which thumbnail list images are superimposed will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a recording list on which thumbnail list images are superimposed by the list generation unit 204 according to the present embodiment.

  As shown by the arrow B in FIG. 3, the thumbnail list image of the recorded program of “title 6” is superimposed so as to be adjacent to “title 6”. In the example illustrated in FIG. 3, the thumbnail list image is displayed below “Title 6”.

  As shown by an arrow B in FIG. 3, the thumbnail list image includes a plurality of thumbnail images a, a cursor b, a time bar c, an arrow d, and thumbnail information e.

  As shown in FIG. 3, the thumbnail list image includes eight thumbnail images a from the first thumbnail image a1 to the eighth thumbnail image a8 in time order. Also, as shown in FIG. 3, the second thumbnail image is a2 in the time order, and the third thumbnail image is a3.

  The cursor b indicates a thumbnail image that is emphasized (selected) among the thumbnail images included in the thumbnail list image. When the display of the thumbnail list image superimposed on the recording list is started, the cursor b is a thumbnail image corresponding to the period to which the playback end position belongs when the recorded program of the title selected in the recording list was played back last time. Is emphasized. Note that the cursor b highlights the thumbnail images arranged at the top in time order among the thumbnail images included in the thumbnail list image when the recorded program of the title selected in the recording list has never been reproduced. do it.

  The cursor b can be moved between thumbnail images included in the thumbnail list image by a user operation of pressing a cross key or the like of the remote controller according to the arrow d. For example, as illustrated in FIG. 3, when the user presses the right button of the cross key on the remote controller while the thumbnail image a2 is selected in the thumbnail list image, the cursor b moves to the thumbnail image a3.

  A time bar c indicates the playback time of the entire recorded program of the selected title. The bar c1 in the time bar c indicates the ratio of the total playback time of the thumbnail images a included in the thumbnail list image to the total playback time of the recorded program of the selected title.

  In addition, the bar c1 is displayed in the time bar c depending on in which period the thumbnail images a included in the thumbnail list image are thumbnail images corresponding to the entire recorded program of the title selected in the recording list. To move.

  The thumbnail information e displays information related to the thumbnail image selected by the cursor b among the thumbnail images a included in the thumbnail list image.

  The thumbnail information e indicates that the thumbnail image selected by the cursor b is the number of thumbnail images in order of time from the first thumbnail image among the thumbnail images generated corresponding to the entire period of the recorded program of “title 6”. Is shown. In the example shown in FIG. 3, the total number of thumbnail images corresponding to the recorded program of “Title 6” is 18 and the thumbnail image selected by the cursor b is the second thumbnail image in time order. ing.

  The thumbnail information e indicates how many minutes after the start point of the recorded program the start point of the corresponding period of the thumbnail image a selected by the cursor b. In the example shown in FIG. 3, the thumbnail information e indicates that the start point of the corresponding period of the thumbnail image a selected by the cursor b is 1 minute 30 seconds after the start point of the recorded program.

  Next, the timing at which the thumbnail images included in the thumbnail list image are switched in the example of the thumbnail list image shown in FIG. 3 will be described. As described above, the cursor b can be moved between thumbnail images included in the thumbnail list image by a remote control operation by the user.

  First, when the user presses the right button of the remote controller a plurality of times (or keeps the pressed state for a predetermined time or more) according to the arrow d, the cursor b moves from the thumbnail image a2 to the thumbnail image a8. In this state, when the right button of the remote controller is further pressed by the user, the cursor b tries to move to the ninth thumbnail image.

  At this time, the list generation unit 204 switches the thumbnail list image to be superimposed on the recording list from the thumbnail list image including the first to eighth thumbnail images to the thumbnail list image including the second to ninth thumbnail images. As a result, the cursor b can be moved to the ninth thumbnail image.

  Further, as described above, when the thumbnail list image including the first to eighth thumbnail images is superimposed on the recording list, the thumbnail list image including the second to ninth thumbnail images is also displayed by the thumbnail list image generation unit 203. Has been generated. Therefore, since the time required for the thumbnail list image switching process can be shortened, the thumbnail list image can be switched smoothly.

  As a result, the recorder 1 can switch the thumbnail list image to be superimposed on the recorded program being reproduced using the thumbnail list image that has already been generated. Accordingly, since it is not necessary to newly generate a thumbnail list image when switching the thumbnail list image to be superimposed on the recorded program being played back, the recorder 1 performs processing related to switching of the thumbnail list image to be superimposed on the recorded program being played back. The time required can be shortened.

  In addition, a thumbnail list image including thumbnail images corresponding to the last period among the divided periods of the recorded program is displayed, and the cursor b highlights the last thumbnail image in time order. When the right button on the remote control is pressed by the user, for example, a blank area is displayed on the right side of the thumbnail image corresponding to the last period, and then a display process is performed to return to the original display. Also good.

  As shown in FIG. 3, the thumbnail list image has been described as an example in which the thumbnail list image is displayed on the lower side of the selected title so as to be adjacent to the selected title. It is not limited to. For example, as shown in FIG. 4, the thumbnail list image may be displayed so as to be superimposed on the upper side of the selected title so as to be adjacent to the selected title. FIG. 4 is a diagram showing another example of a recording list on which thumbnail list images are superimposed by the list generation unit 204 according to the present embodiment.

  When the thumbnail list image cannot be displayed superimposed on the lower side of the selected title (for example, there is no space for displaying the thumbnail list image), the thumbnail list image is displayed above the selected title as shown in FIG. It is sufficient to superimpose and display. In addition, as shown in FIG. 3, the thumbnail list image is displayed superimposed on the lower side of the selected title only when the thumbnail list image cannot be displayed on the upper side of the selected title. May be.

  According to the above configuration, in order to display the thumbnail list image, the recorder 1 divides the display area into the recording list and the thumbnail list image from the state where the recording list is displayed in the entire display area. There is no need to transition to a state. In addition, the visibility of the user is not reduced by reducing the size of the display screen of the recording list.
