Description

  The present invention relates to a technique for reproducing accumulated video information.

In the technology for reproducing video information, a specific content corresponding to a reproduction start position, which is a reproduction position designated by the user, among the reproduction positions preset for the reproduced video information is read out, and the designated reproduction is performed. Various techniques for continuously playing back specific content from a position have been proposed.
For example, the image detection device disclosed in Patent Document 1 displays a timeline, which is a display indicating the total reproduction time, corresponding to the total data amount of the title being reproduced, and a chapter mark is added to the timeline. A triangular mark indicating the position of the image of the target scene is displayed. When the user operates the operation key of the remote controller to select the target triangular mark, the CPU identifies the image corresponding to the selected triangular mark from the position of the selected triangular mark, and reproduces the identified image.

A screen displayed on the touch panel display 200 based on the display control of the reproduction control device 100 will be described with reference to FIG.
FIG. 3 is a diagram showing a display example of the touch panel display 200 according to the first embodiment.
Video information based on the display control of the display control unit 105 of the reproduction control apparatus 100 is displayed on the video display unit 201a of the touch panel display 200.
A video display button 202, a start point movement button 203, and a seek bar 204 are displayed on the operation information display unit 201b of the touch panel display 200. As the video display button 202, a reproduction button 202a, a pause button 202b, a fast forward button 202c, a fast rewind button 202d and a stop button 202e are displayed. As the start point move button 203, a previous start point move button 203a and a next start point move button 203b are displayed. The previous start point move button 203a is a button for performing an operation of moving the reproduction position of the video information to the reproduction start point located immediately before the current reproduction position. The next start point move button 203b is a button for performing an operation of moving the reproduction position of the video information to the reproduction start point located immediately after the current reproduction position.

  The seek bar 204 is a simplified diagram corresponding to the total data amount of the video information displayed on the video display unit 201a and showing the total reproduction time in a linear form. One end of the seek bar 204 shows the start point of the video information, and the other end shows the end point of the video information. On the seek bar 204, a slider 204a indicating the time point of the video information currently being reproduced is superimposed and displayed. Time information of video information is added to each time of the seek bar 204. The display control unit 105 of the reproduction control device 100 performs display control so that the time information of the video information displayed on the video display unit 201a and the time information of the video information added to the seek bar 204 match. Further, on the seek bar 204, start point marks 204b, 204c, and 204d that respectively indicate the positions of the reproduction start point A, the reproduction start point B, and the reproduction start point C set by the information generation unit 102 are displayed in a superimposed manner.

  The operation information display unit 201b is provided with a touch sensor unit 220 that can perform a touch operation by directly touching the video display button 202, the start point movement button 203, and the seek bar 204 described above. When the user presses the image display button 202 or the start point movement button 203 that the user desires to operate, the touch sensor unit 220 detects the coordinates of the pressed area and outputs it to the reproduction control device 100. When the user presses a certain area on the seek bar 204, the touch sensor unit 220 detects the coordinates of the pressed area, the number of touch operations, and the touch operation time, and outputs them to the reproduction control device 100. Furthermore, when the user moves the slider 204a on the seek bar 204, the touch sensor unit 220 detects the coordinates of the area after the movement and outputs the coordinates to the reproduction control device 100 as coordinate information.

Next, a storage example of the reproduction position information storage unit 103 will be shown.
FIG. 4 is a diagram showing an example of reproduction position information accumulated by the reproduction position information accumulating unit 103 of the reproduction control device 100 according to the first embodiment.
FIG. 4 shows reproduction position information corresponding to the three start point marks 204 b , 204 c, 204 d set on the seek bar 204 shown in FIG. 3.
The reproduction position information is composed of coordinates and time information of video information. The coordinates are coordinates indicating the position of the start point marks 204b, 204c, 204d on the seek bar 204 on the touch panel display 200. The reproduction start point A indicates that the coordinates of the start point mark 204b displayed on the seek bar 204 are (A1, A2). It also indicates that the time information of the video information associated with the position of the coordinates (A1, A2) is “00:20:04”.

Next, the operation of the reproduction control device 100 will be described.
FIG. 5 is a flowchart showing the operation of the reproduction control device 100 according to the first embodiment.
In the following description, it is assumed that the display control unit 105 of the reproduction control device 100 sequentially reads out the video information stored in the video information storage unit 106 and outputs it to the video display unit 201a. Further, the processes of steps ST5 to ST8 in the flowchart of FIG. 5 correspond to the process of setting the reproduction start point, and the processes of steps ST9 to ST11 correspond to the process of deleting the reproduction start point. Further, the processing from step ST13 to step ST19 corresponds to the processing when the start point move button 203 in FIG. 3 is pressed, for example. Furthermore, the processes of steps ST20 and ST21 correspond to, for example, the process when the image display button 202 of FIG. 3 is pressed and the process when the slider 204a on the seek bar 204 moves.

  When a touch operation is input to the operation information display unit 201b (step ST1), the operation specifying unit 101 determines whether the touch operation is a seek bar touch operation (step ST2). If the operation is a touch operation on the seek bar (step ST2; YES), the operation identifying unit 101 identifies the number of times of inputting the touch operation on the same area and the input time (step ST3). The information generation unit 102 refers to the information indicating the number of times of inputting the touch operation and the input time to the same area specified in step ST3, the number of touches m is one, and the input time n is the preset threshold time. It is determined whether or not it is less than (step ST4).

  When the number of touches is one and the input time is less than the preset time (step ST4; YES), the information generation unit 102 determines that the touch operation is a reproduction start point registration operation in the touched area. (Step ST5). The information generation unit 102 sets the reproduction start point at the position on the seek bar where the touch operation is performed (step ST6). The information generation unit 102 stores the coordinates of the reproduction start point set in step ST6 and the time information of the video information at the coordinates as reproduction position information of the reproduction start point in the reproduction position information storage unit 103, and the display control unit. It outputs to 105 (step ST7). The display control unit 105 performs display control to display the start point mark on the seek bar based on the output coordinates of the reproduction start point (step ST8).

  On the other hand, when the number of touches is one or when the input time is not less than the preset time (step ST4; NO), the information generation unit 102 determines that the touch operation is a deletion operation of the reproduction start point set in the touched area. It is determined that there is (step ST9). The information generating unit 102 specifies the reproduction position information corresponding to the coordinates on the seek bar where the touch operation is performed from the reproduction position information accumulated in the reproduction position information accumulating unit 103, and deletes it (step ST10). The information generation unit 102 outputs the deleted reproduction position information to the display control unit 105. The display control unit 105 performs display control for deleting the start point mark on the seek bar based on the coordinates of the deleted reproduction position information (step ST11).

  On the other hand, when it is not a touch operation on the seek bar (step ST2; NO), the operation identifying unit 101 determines whether the touch operation is a touch operation on the start point movement button (step ST12). When it is a touch operation on the start point movement button (step ST12: YES), the operation specifying unit 101 further determines whether or not it is a touch operation on the previous start point movement button (step ST13). When it is a touch operation on the previous start point move button (step ST13; YES), the information acquisition unit 104 refers to the reproduction position information storage unit 103, and uses the coordinate information of the point where the current slider is located, The reproduction start point located immediately before the current slider is searched (step ST14).

  On the other hand, when it is not the touch operation on the previous start point movement button (step ST13; NO), that is, when it is the touch operation on the next start point movement button, the information acquisition unit 104 refers to the reproduction position information storage unit 103. The reproduction start point located immediately after the current slider is searched based on the coordinate information of the point where the current slider is located (step ST15). The information acquisition unit 104 acquires the reproduction position information of the reproduction start point searched in step ST14 or step ST15 from the reproduction position information storage unit 103 and outputs it to the display control unit 105 (step ST16). The display control unit 105 acquires the video information to be displayed on the video display unit 201a from the video information storage unit 106 based on the reproduction position information output in step ST16 (step ST17). The display control unit 105 performs display control to display the video information acquired in step ST17 on the video display unit 201a (step ST18). The display control unit 105 also performs display control of moving the slider to the coordinates described in the reproduction position information output in step ST16 (step ST19).

On the other hand, when it is not a touch operation on the start point movement button (step ST12; NO), the operation identifying unit 101 determines that the operation is a touch operation on the image display button or the slider, and determines the operation content of the touch operation from the coordinates of the touch operation. It specifies (step ST20) and outputs the specified operation content to the display control unit 105 together with the coordinate information. The display control unit 105 acquires the video information corresponding to the input operation content and the coordinate information from the video information storage unit 106, and performs display control to display on the video display unit 201a (step ST21).
When the processing of step ST8, step ST11, step ST19, or step ST21 described above ends, the flow returns to the processing of step ST1 and repeats the processing described above.

Next, how each display of the display unit 210 shown in FIG. 3 changes when each process of the flowchart of FIG. 5 is performed will be described with reference to FIG.
FIG. 6A shows a display example of the touch panel display 200 when the operation specifying unit 101 specifies that the touch operation is a reproduction start point registration operation.
When the user presses a certain time point on the seek bar 204 once within a preset time, it is determined that the touch operation is a reproduction start point registration operation in step ST5 of the flowchart of FIG. The information generation unit 102 and the display control unit 105 accumulate the reproduction position information of the new reproduction start point D in steps ST6 to ST8, and display the start point mark 204e of the new reproduction start point D on the seek bar 204. Perform processing to Through these processes, as shown in FIG. 6A, a new start point mark 204e is displayed on the seek bar 204 in a superimposed manner.
The user's touch operation may be slightly displaced from the seek bar 204. Therefore, in consideration of this shift, the operation specifying unit 101 may be configured to determine that the pressing is to select a time point on the seek bar 204 even when the area within the predetermined range from the seek bar 204 is pressed. Good.

On the other hand, when the user presses a certain point on the seek bar 204 a plurality of times or more than a preset time, it is determined that the touch operation is a deletion operation of the reproduction start point in step ST9 of the flowchart of FIG. The information generation unit 102 and the display control unit 105 perform a process of deleting the reproduction position information of the reproduction start point and a process of deleting the start point mark on the seek bar 204 in steps ST10 and ST11. When the display control unit 105 deletes the start point mark, the display of the corresponding start point mark among the start point marks 204b, 204c, and 204d superimposed and displayed on the seek bar 204 shown in FIG. 3 is deleted.
The touch operation of the user may be slightly displaced from the start point mark. Therefore, in consideration of this shift, the operation specifying unit 101 is configured to determine that the operation for deleting the corresponding reproduction start point is performed when a region within a predetermined range from the start point mark is pressed. Good. Further, before performing the process of deleting the start point mark, a process of inquiring of the user whether or not to perform the process of deleting may be performed.

  In the processing example shown in the flowchart of FIG. 5, it is assumed that the seek operation is a touch operation on the seek bar, and if the touch operation is performed once and within a predetermined time, the playback start point is registered. . Further, it is determined that the reproduction start point is deleted when the seek operation is a touch operation, and the touch operation is two or more continuous touch operations or a touch operation of long pressing for a predetermined time or more. It is possible to arbitrarily set what kind of touch operation is performed, ie, the reproduction start point registration operation or the deletion operation, and it may be determined only by the number of touch operations. The determination may be made based on time, and the above-described determination is an example.

FIG. 6B is a display example of the touch panel display 200 when the operation identifying unit 101 identifies a touch operation to the previous start point.
When the user presses the previous start point moving button 203a, it is determined in step ST13 of the flowchart of FIG. 5 that the touch operation is to the previous start point (step ST13; YES). In step ST14, the information acquisition unit 104 searches for the reproduction start point B located immediately before the slider 204a shown in FIG. The information acquisition unit 104 and the display control unit 105 perform processing for starting reproduction from the position of the start point mark 204c of the reproduction start point B in steps ST16 to ST19. By these processes, as shown in FIG. 6B, the reproduction position of the video information is changed to the time point of the start point mark 204c, the video information at the start point mark 204c is displayed on the video display unit 201, and the slider 204a is moved to the seek bar 204. Is displayed over the start point mark 204c. In this way, when the user presses the previous start point move button 203a, the slider 204a indicating the current reproduction position is returned to the reproduction start point B located immediately before.

FIG. 6C is a display example of the touch panel display 200 when the operation identifying unit 101 identifies a touch operation to the next start point.
When the user presses the next start point moving button 203b, it is determined in step ST13 of the flowchart of FIG. 5 that the touch operation is not the previous start point (step ST13; NO). In step ST15, the information acquisition unit 104 searches for the reproduction start point C located immediately after the slider 204a shown in FIG. The information acquisition unit 104 and the display control unit 105 perform processing for starting reproduction from the position of the start point mark 204d of the reproduction start point C in steps ST16 to ST19. By these processes, as shown in FIG. 6C, the reproduction position of the video information is changed to the point of the start point mark 204d, the video information at the start point mark 204d is displayed on the video display unit 201, and the slider 204a is moved to the seek bar 204d. Is displayed over the start point mark 204d. In this way, when the user presses the next start point move button 203b, the slider 204a indicating the current reproduction position is skipped to the reproduction start point C located immediately after.

  As described above, according to the first embodiment, the video information is displayed on the video display unit 201a of the display unit 210 based on the video information, and the total reproduction of the video information is performed on the operation information display unit 201b of the display unit 210.

Since it is configured to perform the control displayed above, it is possible to generate the information regarding the reproduction position of the video while confirming the displayed video information. Thus, the operation of setting the reproduction start point, the operation of deleting the reproduction start point, and the like can be easily instructed with a small number of operations while checking the video information. Also, the playback position can be specified without depending on the user's operation.

  Further, according to the first embodiment, the operation specifying unit 101 relates to the operation or the reproduction position for setting the information regarding the reproduction position of the video information based on the coordinates of the area where the touch operation is input and the mode of the touch operation. When the operation specifying unit 101 specifies that the operation for deleting information is the operation for setting the information regarding the reproduction position, the information generation unit 102 newly sets the reproduction start point indicating the reproduction position on the seek bar. When the operation specifying unit 101 specifies that the operation is to delete the information related to the reproduction position, the information of the reproduction start point indicated on the seek bar is deleted, so that the user can It is possible to easily set the reproduction start point on the seek bar or delete the reproduction start point on the seek bar while confirming the information. Also, by setting the playback start point, when the user moves to the point where he or she wants to see the playback position of the video information, there is no need to operate the slider on the seek bar to move to the desired point, By touching the start point, a fixed reproduction start point can be designated each time. As a result, it is possible to suppress the occurrence of the problem that the reproduction start point is deviated for each operation.

  Further, according to the first embodiment, the display control unit 105 includes the information acquisition unit 104 that acquires information for changing the reproduction position of the video information according to the operation content specified by the operation specification unit 101.
