In the present invention, the storage means of the video playback apparatus stores playback history information. The reproduction history information includes information regarding a reproduction position where the main reproduction of the video data is interrupted. The reproduction position is an abstract concept that is conceived when the video data portions are arranged in chronological order, and does not necessarily correspond to the physical position on the recording medium on which the video data is recorded. The reproduction position means information for specifying the video data portion where the main reproduction is interrupted.
With this information, it becomes possible to specify the interrupt position of the main reproduction, the reproduced part of the video data, and the unreproduced part. The interruption position means the part of the video data that was actually reproduced when the actual reproduction was interrupted. The played part corresponds to the video data part that was played back before the time when the main playback was interrupted, and the unplayed part should be played back after the time when the main playback was interrupted. Corresponds to the video data part.
When the selecting means selects the video data to be temporarily reproduced, the generating means designates the temporary reproduction start position of the video data, that is, the video data portion to start the temporary reproduction based on the reproduction history information corresponding to the video data. Temporary reproduction start information to be generated is generated. The provisional reproduction means provisionally reproduces the video data from the video data portion indicated by the generated provisional reproduction start information.
Therefore, with respect to the video data for which the main reproduction is interrupted, the temporary reproduction can be selectively started from the reproduction position where the main reproduction is interrupted, the reproduced part, or the unreproduced part.
When video data is provisionally reproduced from the main reproduction interruption position or the non-reproduction portion, the user can view the main reproduction interruption portion or the non-reproduction portion and select the main reproduction target video data. When the video data is provisionally reproduced from the reproduced part, the user can check the video viewed last time and select the video data to be reproduced.
Note that the method for temporarily reproducing video data is not particularly limited. For example, the video data may be reproduced with a small image, or may be configured to be reproduced with the same resolution and screen size as the main reproduction.

In the present invention, the elapsed time from the time point when the main reproduction of the video data is interrupted is measured by the time measuring means.
Then, when the elapsed time from the time when the main reproduction is interrupted is short, the generating means reproduces the video data that has been reproduced at the reproduction position after the main reproduction interruption position, that is, the video data that was reproduced at the time when the main reproduction was interrupted. Temporary playback start information is generated that designates a video data portion that should have been played back after the portion or the point at which the playback was interrupted. When the elapsed time since the main reproduction of the video data is interrupted is short, the user's memory for the video data is expected to be clear, and after the main reproduction interruption position compared to the reproduced part in the user's memory. It is considered that the unreproduced portion of the image contributes to search for desired video data. For this reason, provisional reproduction start information for specifying a reproduction position after the main reproduction interruption position of the video data, that is, an unreproduced reproduction position is generated.
In addition, when the elapsed time from the time when the main playback is interrupted is long, the generating means performs the main playback before the video data main playback interrupt position, that is, before the main playback is interrupted. Temporary reproduction start information for designating the video data portion is generated. If a long time has elapsed since the main playback of the video data was interrupted, the user's memory for the video data may be weakened, and the reproduced part is more desirable than the unreproduced part. It is thought to contribute to the search of video data. For this reason, in order to recall the contents of the video data, provisional reproduction start information for designating a reproduced reproduction position is generated.
Therefore, it is possible to effectively support the search for video data.

In the present invention, the reproduction history information includes information regarding the reproduction position where the temporary reproduction of the video data is interrupted. Note that the playback position where the temporary playback is interrupted is not only the playback position when the temporary playback is forcibly terminated by the user's operation, but also a part of the video data is temporarily played back, and the temporary playback is automatically performed. The playback position at the end is also included. Similarly to the interruption position, the reproduction position at which the temporary reproduction is interrupted is an abstract concept that is conceived when the video data portions are arranged in time series, and is not necessarily physically recorded on the recording medium on which the video data is recorded. It does not correspond to the target position. The reproduction position where the temporary reproduction is interrupted means information for specifying the video data portion where the temporary reproduction is interrupted.
When the selection means selects video data to be temporarily reproduced, it is determined whether or not the video data has been temporarily reproduced based on the reproduction history information corresponding to the video data. When it is determined that the video data is the temporary playback interrupted, the generation unit specifies the video data portion to start the temporary playback based on the information for specifying the video data portion of the temporary playback interrupted. Temporary reproduction start information is generated.
Accordingly, with respect to video data for which temporary playback has been interrupted, temporary playback can be selectively performed from the temporary playback interruption position, the reproduced portion, or the unreproduced portion as necessary.

  In the present invention, the order of provisional reproduction of a plurality of video data is determined based on predetermined information regarding the video data. For example, the provisional reproduction order of the video data is determined based on the date and time when the video data was created, the date and time when the video data was recorded on the recording medium, the file name of the video data, the ratio of the viewed time, and the like. Then, the selection means sequentially selects the plurality of video data in ascending order or descending order, and the temporary reproduction means provisionally reproduces the sequentially selected video data.

In the present invention, when the progressive operation unit is operated and video data to be temporarily reproduced is selected, when the selected video data is the actual reproduction interrupted video, the temporary reproduction means interrupts the actual reproduction. The video data is temporarily reproduced from the reproduced reproduction position or a reproduction position after a predetermined reproduction time from the reproduction position. In other words, the provisional reproduction means performs provisional reproduction from the video data portion that has been reproduced at the time when the main reproduction is interrupted or the video data portion that should have been reproduced after the point at which the main reproduction is interrupted.
When video data to be provisionally played is selected by operating the reverse feed operation unit, when the selected video data is the main playback interrupted video, the main playback is interrupted or a predetermined playback from the playback position. Temporarily play back video data from before time. In other words, the provisional reproduction means performs provisional reproduction from the video data portion that has been actually reproduced at the time when the main reproduction is interrupted or the video data portion that has been actually reproduced before the time when the main reproduction is interrupted.
When the forward operation unit or the reverse operation unit is operated and video data to be temporarily reproduced is selected, when the selected video data is not the actual reproduction interrupted video, the temporary reproduction means temporarily reproduces from the head of the video data. .
Accordingly, it is possible to effectively support the search for video data by appropriately changing the playback position at which provisional playback is started in accordance with the operation contents of the forward operation unit and the reverse operation unit.

In the present invention, when one video data to be temporarily reproduced is selected, if it is determined that the video data is not the video data for which the main reproduction has been interrupted, the selection means selects other video data.
Accordingly, it is possible to effectively support the search for video data for which the main reproduction has been interrupted.

In the present invention, when one piece of video data to be temporarily reproduced is selected, when it is determined that the video data is not unreproduced, the selection unit selects other video data.
Therefore, it is possible to effectively support the search for unreproduced video data.

In the present invention, the selection means determines that the selected video data is not the actual playback interrupted video when the forward operation unit is operated and one video data to be temporarily reproduced is selected. If another video data is selected, another video data is selected. When it is determined that the selected one video data is the main playback interrupted video, the temporary playback means temporarily plays back from the main playback interrupt position of the video data or the playback position after the predetermined playback time of the main playback interrupt position. . In other words, the provisional reproduction means provisionally reproduces from the video data portion that was actually reproduced at the time when the main reproduction was interrupted or from the video data portion that should have been reproduced after the time when the main reproduction was interrupted. To do.
Therefore, when the forward operation unit is operated, only the reproduction interruption video is selected. In addition, since the selected video data is temporarily reproduced from the main reproduction interruption position or a predetermined reproduction time after the main reproduction interruption position, it is possible to effectively support the search of the video data in which the main reproduction is interrupted. Become.
In addition, when the reverse operation unit is operated and one video data to be temporarily reproduced is selected, the selection unit determines that the selected one video data is not an unreproduced video. Select data. When it is determined that the selected video data is an unreproduced video, the temporary playback means temporarily plays back from the beginning of the video data.
Therefore, when the reverse operation unit is operated, only unreproduced video is selected. In addition, since provisional reproduction is performed from the top of the selected video data, it is possible to effectively support the search for unreproduced video data.

  According to the present invention, when a part of each of a plurality of video data is provisionally reproduced and the search for the main reproduction target to be continuously reproduced is supported, the temporary reproduction position corresponding to the reproduction history of the video data is By temporarily reproducing the video data, the video data search can be supported more effectively than the conventional video search support method.

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.
FIG. 1 is a block diagram schematically showing the configuration of a video playback apparatus 1 according to an embodiment of the present invention. The video playback device 1 according to the embodiment of the present invention is, for example, a hard disk recorder, and video data is obtained by temporarily playing a part of each of a plurality of video data from a playback position corresponding to the playback history of the video data. This makes it possible to effectively support the search for.
The video playback apparatus 1 according to the embodiment of the present invention includes a control unit 10 that controls the operation of each component of the video playback apparatus 1 and an input unit 11 that receives a broadcast signal, a video signal, and the like received by the antenna A. Prepare.

  The control unit 10 is composed of a microcomputer including a CPU, a ROM, a RAM, and the like, and controls the operation of the components by giving control signals to the components.

The input unit 11 includes a TV tuner unit 11a, an IP broadcast tuner unit 11b, and an external input unit 11c.
The TV tuner unit 11a is, for example, a BS / CS digital tuner, a terrestrial digital tuner, or the like, which amplifies broadcast signals such as terrestrial digital and BS / CS received by the antenna A, and selects a selection given from the control unit 10. A broadcast signal of a specific frequency channel is selected based on the station signal. In addition, the TV tuner unit 11a demodulates the selected broadcast signal, and supplies the video data obtained by the demodulation to the codec unit 13. For example, a terrestrial digital broadcast signal is modulated by an OFDM (Orthogonal Frequency Division Multiplexing) system, and a demodulator demodulates the broadcast signal into video data in the MPEG2TS (Transport Stream) format and demodulates the video data. Is given to the codec section 13.

  For example, the IP broadcast tuner unit 11b receives a video signal distributed from the IP broadcast server 2 via a communication network such as the Internet (not shown), executes various processes such as demodulation on the received video signal, and obtains the received video signal. The obtained video data is given to the codec unit 13.

  The external input unit 11c is an interface for inputting a video signal output from the external video output device 3 such as an externally connected hard disk recorder, DVD player, or video camera, and demodulates the input video signal as necessary. The video data obtained by the processing is supplied to the codec unit 13.

  The codec unit 13 decodes the video data given from the input unit 11 or the video data storage unit 12 based on the reproduction control signal output from the control unit 10, and sends the decoded video data to the output control unit 14. give. In addition, the codec unit 13 encodes video data based on the recording control signal output from the control unit 10, and provides the encoded video data to the video data storage unit 12.

  The video data storage unit 12 is a non-volatile storage medium that stores video data, such as a hard disk drive or an SSD (Solid State Drive), and stores the video data encoded by the codec unit 13.

  The output control unit 14 performs D / A conversion on the video data and audio data supplied from the codec unit 13, and supplies the D / A converted signal to the output unit 15. For example, the output control unit 14 generates a right sound analog audio signal, a left sound analog audio signal, and a composite video signal, and supplies them to the output unit 15.

  The output unit 15 includes a video output unit 15a and an audio output unit 15b. The video output unit 15a outputs the composite video signal to an external video display device such as a liquid crystal display device. The audio output unit 15b outputs an audio signal to an external speaker.

  The video playback device 1 also includes a remote control device 16 for operating the video playback device 1 and a remote control signal receiver 17.

  The remote operation device 16 includes at least a forward operation unit 16a and a reverse operation unit 16b, and transmits an infrared remote operation signal corresponding to the operation state of various operation units. The forward operation unit 16a and the reverse operation unit 16b are operation means for the user to select video data to be temporarily reproduced and to be reproduced. The user can instruct switching of video data to be temporarily reproduced by operating the forward operation unit 16a or the reverse operation unit 16b.

  The remote operation signal receiver 17 receives the remote operation signal transmitted from the remote operation device 16 and detects the operation state of the remote operation device 16. The detected operation state is output to the control unit 10.

Furthermore, the video reproduction apparatus 1 includes a storage unit 18 and a time measuring unit 19.
The timer unit 19 has a function of measuring the current date and time and notifying the controller 10 of the current date and time in response to a request from the controller 10.
The storage unit 18 is a non-volatile memory and stores a video list 18a. The video list 18 a includes information regarding the playback history of video data stored in the video data storage unit 12.

FIG. 2 is an explanatory diagram conceptually illustrating an example of the video list 18a. The video list 18 a is a table for storing information related to the playback history of video data stored in the video data storage unit 12 and video data stored in the IP broadcast server 2 or the external video output device 3. Hereinafter, the video data stored in the video data storage unit 12 will be described for the sake of simplicity. The table of the video list 18a includes a plurality of columns (fields), for example, a “video data identification ID” column, an “acquisition date / time” column, a “main reproduction interruption date / time” column, and a “main reproduction interruption position” column. Each row (record) has information stored in each column. The “video data identification ID” column stores a numerical value or a character string unique to the video data, the “acquisition date / time” column stores the date / time when the corresponding video data was acquired, The date and time when the main reproduction of the video data was interrupted is stored, and the “main reproduction interruption position” column stores the reproduction position where the main reproduction of the corresponding video data was interrupted. Note that the playback position at which the main playback is interrupted means information for specifying the video data portion that has been played back at the time when the main playback is interrupted.
For example, the video data with the video data identification ID 0017 is acquired at 0:00 on January 1, 2008 and stored in the video data storage unit 12. The video data is interrupted at 13:15:20 on January 1, 2008. The total playback time of the video data is 60 minutes, and the main playback is interrupted when playback is performed for 25 minutes and 25 seconds from the beginning.
On the other hand, the video data with the video data identification ID 0020 was acquired at 13:00 on January 1, 2008 and stored in the video data storage unit 12. The information about the main reproduction interruption date and time and the main reproduction interruption position corresponding to the video data is not stored, which means that the main reproduction has not been interrupted in the past.

  Next, the processing procedure of the control unit 10 will be described. First, a processing procedure related to acquisition and storage of video data, a main playback of stored video data, and a processing procedure related to interruption of the main playback will be described, and finally a processing procedure related to temporary playback of video data. Will be explained.

  FIG. 3 is a flowchart showing a processing procedure of the control unit 10 related to acquisition and accumulation of video data. The user can instruct acquisition of video data by operating the remote operation device 16, and the control unit 10 receives the instruction via the remote operation signal receiving unit 17. When receiving an instruction to acquire video data, the control unit 10 acquires specific video data (step S11), and stores the acquired video data in the video data storage unit 12 (step S12).

  Next, the control unit 10 acquires the date and time when the video data is acquired from the time measuring unit 19, that is, the current date and time (step S13). Then, the video data identification IDs in order of acquisition date and time are recorded in the video list 18a (step S14). Then, the control unit 10 records the acquired date and time in the video list 18a (step S15), and ends the processing related to acquisition and accumulation of video data.

  FIG. 4 is a flowchart showing a processing procedure of the control unit 10 relating to the main reproduction of the stored video data and the interruption of the main reproduction. The user can instruct the main reproduction of the video data and the interruption of the main reproduction by operating the remote operation device 16, and the control unit 10 receives the instruction via the remote operation signal receiving unit 17. For example, when the forward operation unit 16a and the reverse operation unit 16b are not operated for a predetermined time or longer in the video search support mode described later, the control unit 10 is instructed to perform main reproduction of the video data currently being temporarily reproduced. recognize. When receiving the instruction for the main reproduction, the control unit 10 sequentially reads out the video data selected by the user from the video data storage unit 12, and performs the main reproduction of the video data (step S31). Next, the control unit 10 determines whether or not the interruption of the main reproduction has been received via the remote operation signal receiving unit 17 (step S32). When it is determined that the interruption of the main reproduction has not been accepted (step S32: NO), the control unit 10 returns the process to step S31 and continues the main reproduction of the video data.

When it is determined that the interruption of the main reproduction has been accepted (step S32: YES), the control unit 10 acquires the date and time when the main reproduction was interrupted from the time measuring unit 19, that is, the current date and time (step S33), and the main reproduction is interrupted. In association with the video data thus recorded, the date and time acquired in step S33 is recorded in the video list 18a as the actual playback interruption date and time (step S34). Next, the control unit 10 records the main reproduction interruption position at which the main reproduction is interrupted in the video list 18a in association with the video data at which the main reproduction is interrupted (step S35), and performs the main reproduction of the video data and the main data. The process related to the interruption of playback is finished.
When the main reproduction of one video data is interrupted a plurality of times, when the main reproduction interruption date and time and the main reproduction interruption position are already recorded in the video list 18a, the control unit 10 updates the reproduction interruption position. It is configured.

  When the main playback is interrupted, if the main playback interrupt date and time and the main playback interrupt position have been recorded in the video list 18a, the recorded playback interrupt position is compared with the unrecorded playback interrupt position. When the reproduction interruption position of the recording is behind the recorded reproduction interruption position, the main reproduction interruption date and time and the main reproduction interruption position may be updated.

  FIG. 5 is a flowchart showing a processing procedure of the control unit 10 related to video selection according to the embodiment of the present invention, and FIGS. 6 and 7 conceptually illustrate the video search support method according to the embodiment of the present invention. FIG.

  The control unit 10 monitors the reception state of the remote operation signal receiving unit 17, and shifts to the video search support mode when the forward operation unit 16a or the reverse operation unit 16b is pressed for a predetermined time or longer, that is, when pressed for a long time. . In the video search support mode, the control unit 10 monitors the reception state of the remote operation signal reception unit 17 to determine whether or not the forward operation unit 16a of the remote operation device 16 has been operated (step S51). When it is determined that the forward operation unit 16a has been operated (step S51: YES), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the video data of the provisional reproduction target is ascending order. (Step S52).

  Next, based on the video list 18a, the control unit 10 determines whether the video data selected in step S52 is a main playback interrupted video, that is, whether the main playback has been interrupted in the past. Is determined (step S53).

  If it is determined that the video is the main playback interrupted video (step S53: YES), the control unit 10 determines the main playback interrupting position as the temporary playback start position as shown in FIG. 6A (step S54). The provisional reproduction start position means provisional reproduction start information for designating a video data portion where the provisional reproduction of video data is started. If it is determined that the video is not the actual playback interrupted video (step S53: NO), the control unit 10 determines the head of the video data as the temporary playback start position as shown in FIG. 6B (step S55).

  When it is determined in step S51 that the reverse feed operation unit 16b has been operated (step S51: NO), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the provisional reproduction target video data. Are selected in descending order (step S56).

  Next, the control unit 10 determines whether or not the video data selected in step S56 based on the video list 18a is a main playback interrupted video, that is, whether or not the main playback has been interrupted in the past. Is determined (step S57).

  When it determines with it being this reproduction | regeneration interruption video (step S57: YES), the control part 10 acquires the present date and time from the time measuring part 19 (step S58), and video data based on the acquired date and video list 18a. The elapsed time from the time point of the main reproduction interruption is calculated, and the calculated elapsed time is compared with a predetermined time, for example, 3 hours, 24 hours, 7 days, and 30 days (step S59). Next, based on the comparison result, the control unit 10 determines a specific position corresponding to the elapsed time, that is, a predetermined time before the actual reproduction interruption position as a temporary reproduction start position as shown in FIG. S60).

  FIG. 8 is a chart showing the relationship between the elapsed time from the reproduction interruption date and time and the temporary reproduction start position. The left column of the chart shows the elapsed time from the date and time when the video data was completely interrupted, and the right column of the chart shows the temporary playback start position of the video data. As shown in the figure, the control unit 10 determines the main reproduction interruption position as the temporary reproduction start position when the elapsed time from the main reproduction interruption date is 3 hours or less. Further, when the elapsed time is more than 3 hours and 24 hours or less, 5 seconds before the actual playback interruption position, and when the elapsed time is more than 24 hours and 7 days or less, 10 seconds before the actual playback interruption position, When the elapsed time is longer than 7 days and not longer than 30 days, the head of the video data is determined as the temporary playback start position, respectively, 5 minutes before the actual playback interruption position and when the elapsed time is longer than 30 days.

  When it is determined in step S57 that the video is not the actual playback interrupted video (step S57: NO), the control unit 10 determines the head of the video data as a temporary playback start position as shown in FIG. S61).

When the processes of steps S54, 55, 60, and 61 are completed, the control unit 10 temporarily reproduces a part of the video data from the determined provisional reproduction start position (step S62), and the process is terminated.
When the forward operation unit 16a or the reverse operation unit 16b is operated during temporary reproduction, the same processing is executed. In the video search support mode, when the forward operation unit 16a and the reverse operation unit 16b are not operated for a predetermined time or longer, the control unit 10 shifts from the video search support mode to the main playback mode, and is currently in temporary playback. Perform full playback of video data.

Next, operations and effects of the video recording / reproducing apparatus 1 according to the present invention will be described.
The user can shift the operation state of the video reproduction device 1 to the video search support mode by long pressing the forward operation unit 16a or the reverse operation unit 16b. Then, the user operates the forward operation unit 16a in the video search support mode to temporarily reproduce the plurality of video data stored in the video data storage unit 12 in ascending order of the acquisition date of the video data. By operating the reverse operation unit 16b, the video data can be temporarily reproduced sequentially in the descending order of the acquisition date and time. When the sequential playback operation unit 16a is operated to select the main playback interrupted video, the video data to be temporarily played back is temporarily played back from the main playback interrupt position as shown in FIG. When the reverse feed operation unit 16b is operated to select the main playback interrupted video, the video data to be temporarily played back is temporarily played before the main playback interrupted position as shown in FIG. 6B.

Therefore, in the present embodiment, the control unit 10 can provisionally reproduce a part of the video data from the provisional reproduction position corresponding to the reproduction history of the video data, and the user can perform forward operation. By operating the unit 16a or the reverse feed operation unit 16b, the temporary reproduction start position can be changed. Therefore, it is possible to support the search of video data more effectively than the conventional video search support method.
Further, the user can intuitively select the provisional reproduction start position, and can efficiently select desired video data. The reason is as follows. The forward operation unit 16a selects video data to be provisionally reproduced in ascending order of acquisition date and time, and provisionally reproduces the vicinity of the main reproduction interruption position, particularly an unreproduced portion, both of which have a meaning in the future direction. On the other hand, the reverse operation unit 16b selects video data to be provisionally reproduced in descending order of acquisition date and provisionally reproduces from the beginning of the video data, both of which have a meaning in the past direction. Accordingly, the user can perform intuitive operations.

  Furthermore, the video reproduction apparatus 1 according to the embodiment is configured to perform provisional reproduction far backward from the reproduction interruption position as the elapsed time after the main reproduction is interrupted is longer. Therefore, the longer the time elapsed since the main playback was interrupted, the more information can be given to remind the user of the content of the video viewed by the user in the past, and the user can search for the desired video data more effectively. Can help.

  In the present embodiment, the remote operation device and the remote operation signal receiving unit having the forward operation unit and the reverse operation unit have been described as the configuration of the operation unit for performing forward and backward feeding of video data. Needless to say, the configuration is not limited to this. The operation unit may be configured with other configurations, for example, a pointing device, as long as the configuration can operate forward and reverse video data.

  Also, the video data stored in the video data storage unit has been described as a playback target. However, the present invention is applied to the case where video data stored in an IP broadcast server or an external video output device is received and directly played back. You may do it.

  Further, an example has been described in which the provisional reproduction order of the video data is determined based on the acquisition date and time of the plurality of pieces of video data, and each piece of video data is provisionally reproduced in ascending order or descending order. It is not limited. For example, the provisional reproduction order of the video data may be determined based on the file name of the video data, and the video data may be sequentially reproduced in ascending or descending order with the arrangement direction of alphanumeric characters and kana characters as the forward direction. good. Alternatively, only unreproduced video data or only reproduced video data may be selectively temporarily reproduced in ascending or descending order. Further, the provisional reproduction order of a plurality of video data is determined in the order of the reproduction time ratio of the video data, that is, the ratio of the reproduction time that has been reproduced with respect to the total reproduction time of the video data, and each video data is sequentially arranged in ascending order or descending order. You may comprise so that provisional reproduction may be carried out. Furthermore, the video data to be temporarily reproduced may be selected at random and temporarily reproduced. Furthermore, a plurality of video data may be arranged by appropriately combining these arrangement methods.

Furthermore, as an example, a case has been described in which the sequential playback operation unit 16a is operated and it is determined that the video data is interrupted from the main playback, and the video data is played from the main playback interrupt position. It is not particularly limited to this.
Furthermore, although a hard disk recorder has been described as an example of a video playback device, any other device, such as a TV personal computer, can be used as long as it can playback video data recorded in an internal or external video data storage unit. The present invention may be applied to a display device with a video reproduction function, a DVD recorder, a BD recorder, and the like.

(Modification 1)
FIG. 9 is a flowchart showing a processing procedure of the control unit 10 related to video selection in the first modification, and FIG. 10 is an explanatory diagram conceptually showing a video search support method in the first modification. The control unit 10 determines whether or not the forward operation unit 16a of the remote operation device 16 has been operated by monitoring the reception state of the remote operation signal reception unit 17 as in the above embodiment (step S111). . When it is determined that the forward operation unit 16a has been operated (step S111: YES), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the video data of the provisional reproduction target is ascending order. (Step S112).

  Next, the control unit 10 determines whether or not the video data selected in step S112 is a main reproduction interrupted video, that is, whether or not the video data has been interrupted in the past (step S113). ).

  When it is determined that the video is the main playback interrupted video (step S113: YES), the control unit 10 determines a position after a predetermined time from the main playback interrupting position as a temporary playback start position, as shown in FIG. (Step S114). When it is determined that the video is not the actual playback interrupted video (step S113: NO), the control unit 10 determines the head of the video data as the temporary playback start position (step S115).

  If it is determined in step S111 that the reverse feed operation unit 16b has been operated (step S111: NO), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and determines one of the provisional reproduction targets. The video data is selected in descending order (step S116).

  Next, the control unit 10 determines whether or not the video data selected in step S116 is a main reproduction interrupted video, that is, whether or not the video data has been interrupted in the past (step S117). ).

  When it is determined that the video is the main playback interruption video (step S117: YES), the control unit 10 determines a position before the main playback interruption position for a predetermined time as a temporary playback start position, as shown in FIG. (Step S118). When it is determined that the video is not the actual playback interrupted video (step S117: NO), the control unit 10 determines the head of the video data as the temporary playback start position (step S119).

  When the processes of steps S114, 115, 118, and 119 are completed, the control unit 10 temporarily reproduces part of the video data from the determined provisional reproduction start position (step S120), and the process is terminated.

The video playback device 1 according to the modified example 1 is configured to perform provisional playback after a predetermined playback time at the main playback interruption position when the reverse playback operation unit 16b is operated and the main playback interruption video is selected. Yes.
Since the user is viewing the video up to the actual playback interruption position, even if the video data is temporarily reproduced from the main reproduction interruption position, the content is within the range inferred from the content of the viewed video. There is a possibility that desired video data cannot be efficiently searched.
However, according to the first modification, the video data can be temporarily reproduced after the predetermined reproduction time at the main reproduction interruption position, so that information effective for the retrieval of the video data can be given to the user. Search can be supported more effectively.

  Note that the temporary reproduction start position shown in the first modification is an example. When the forward operation section 16a is operated and the main reproduction interruption video is selected, provisional reproduction is started from the reproduction position after the main reproduction interruption position, the reverse operation section 16b is operated, and the main reproduction interruption position is selected. In this case, other provisional reproduction start positions may be adopted as long as the provisional reproduction is started from a position before the reproduction interruption position.

  For example, when the forward operation unit 16a is operated and the main reproduction interruption video is selected, provisional reproduction is started from the main reproduction interruption position, and when the reverse operation unit 16b is operated and the main reproduction interruption position is selected, You may comprise so that provisional reproduction | regeneration may be started from the head of video data.

In such a configuration, the user can use the temporary playback from the main playback interruption position and the temporary playback from the beginning of the video data by operating the forward operation unit 16a or the reverse operation unit 16b. it can. The user may select the temporary reproduction start position according to the video data search method. For example, if it is desired to search the desired video data by viewing the head portion of the video data, the reverse operation unit 16b is operated, and if it is desired to search the video data whose main reproduction has been interrupted, the forward operation unit 16a may be operated. .
In addition, when the user operates the forward operation unit 16a, if video data to be temporarily reproduced appears from the beginning, the user can operate the backward operation unit 16b after performing the forward operation once, thereby Data can be temporarily reproduced from the beginning.
Further, when the user operates the reverse operation unit 16b, if video data to be temporarily reproduced appears from the main reproduction interruption position, the reverse operation is performed once, and then the forward operation unit 16a is operated. Thus, the video data can be temporarily reproduced from the main reproduction interruption position.

As described above, the provisional reproduction position can be selected using the forward operation unit 16a and the reverse operation unit 16b for selecting video data to be provisionally reproduced.
Therefore, the complicated operation of designating the reproduction start position from other operation buttons, menu screens, or the like is not necessary.

(Modification 2)
FIG. 11 is an explanatory diagram conceptually illustrating an example of the video list 218a in the second modification. In the video list 218a according to the second modification, the rearrangement list includes a plurality of columns, a “video data identification ID” column, an “acquisition date / time” column, a “main playback interruption date / time” column, In addition to the “main reproduction interruption position” column, the column is composed of a “temporary reproduction interruption position” column, and each row has information stored in each column. The “temporary reproduction interruption position” stores a position where reproduction is interrupted in the temporary reproduction of video data. Note that the position where reproduction is interrupted in provisional reproduction means information for specifying a video data portion where provisional reproduction is interrupted.

  12 and 13 are flowcharts illustrating the processing procedure of the control unit 10 according to the video selection in the second modification. The control unit 10 determines whether or not the forward operation unit 16a of the remote operation device 16 has been operated by monitoring the reception state of the remote operation signal reception unit 17 as in the above embodiment (step S211). . When it is determined that the forward operation unit 16a has been operated (step S211: YES), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the video data of the provisional reproduction target is ascending order. (Step S212).

  Next, the control unit 10 determines whether or not the video data selected in step S212 is a temporary playback interrupted video, that is, whether or not the video has been temporarily played back in the past (step S213). ).

  If it is determined that the video is a temporary playback interrupted video (step S213: YES), the temporary playback interrupted position is determined as the temporary playback start position (step S214). When it is determined that the video is not the temporary playback interrupted video (step S213: NO), the control unit 10 determines whether the video data selected in step S212 is the main playback interrupted video (step S215).

  When it determines with it being a main reproduction | regeneration interruption video (step S215: YES), the control part 10 determines a main reproduction | regeneration interruption position as a temporary reproduction start position (step S216). When it is determined that the video is not the actual playback interrupted video (step S215: NO), the control unit 10 determines the head of the video data as the temporary playback start position (step S217).

  When it is determined in step S211 that the reverse feed operation unit 16b has been operated (step S211: NO), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the video data to be provisionally reproduced. Are selected in descending order (step S218).

  If it is determined that the video is a temporary reproduction interrupted video (step S219: YES), the temporary reproduction interruption position is determined as the temporary reproduction start position (step S220). If it is determined that the video is not a temporary playback interrupted video (step S219: NO), it is determined whether the video data selected in step S218 is a main playback interrupted video (step S221).

  When it determines with it being this reproduction | regeneration interruption video (step S221: YES), the control part 10 acquires the present date and time from the time measuring part 19 (step S222), and based on the acquired date and video list 218a, video data The elapsed time from the main reproduction interruption time is calculated, and the calculated elapsed time is compared with the predetermined time (step S223). Next, based on the comparison result, the control unit 10 determines a specific position corresponding to the elapsed time, that is, a predetermined time before the main reproduction interruption position, as a temporary reproduction start position (step S224).

  If it is determined in step S221 that the video is not the actual playback interrupted video (step S221: NO), the control unit 10 determines the head of the video data as the temporary playback start position (step S225).

  When the processes in steps S214, 216, 217, 220, 224, and 225 are completed, the control unit 10 temporarily reproduces a part of the video data from the determined provisional reproduction start position (step S226), and ends the process.

  In the video playback device 1 according to the modified example 2, in the video search support mode, when a video for which temporary playback has been interrupted in the past is selected, the video is temporarily played from the temporary playback interrupt position. Even if provisional reproduction is performed a plurality of times, there is no provisional reproduction overlapping from the main reproduction interruption position or the temporary reproduction interruption position. Therefore, it is possible to more effectively support the search for video data.

(Modification 3)
FIG. 14 is a flowchart illustrating a processing procedure of the control unit 10 according to video selection in the third modification. As in the above-described embodiment, the control unit 10 determines whether or not the forward operation unit 16a of the remote operation device 16 has been operated by monitoring the reception state of the remote operation signal reception unit 17 (step S311). . If it is determined that the forward operation unit 16a has been operated (step S311: YES), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and the video data of the provisional reproduction target is ascending order. (Step S312).

  Next, the control unit 10 determines whether or not the video data selected in step S312 is the main reproduction interrupted video (step S313). When it determines with it not being this reproduction | regeneration interruption video (step S313: NO), the control part 10 selects another video data in an ascending order (step S314), and returns a process to step S313.

  When it determines with it being a main reproduction | regeneration interruption video (step S313: YES), the control part 10 determines a main reproduction | regeneration interruption position as a temporary reproduction start position (step S315).

  If it is determined in step S311 that the reverse feed operation unit 16b has been operated (step S311: NO), the control unit 10 determines the provisional reproduction order of the video data based on the video list 18a, and sets one of the provisional reproduction targets. Video data is selected in descending order (step S316).

  Next, the control unit 10 determines whether the video data selected in step S316 is unreproduced video data based on the video list 18a (step S317). If it is determined that the video data is not unreproduced (step S317: NO), the control unit 10 selects other video data in descending order (step S318), and returns the process to step S317.

  When it is determined that the video data has not been played back (step S317: YES), the control unit 10 determines the head of the video data as a temporary playback start position (step S319).

  When the processes in steps S315 and 319 are completed, the control unit 10 reproduces a part of the video data from the determined provisional reproduction start position (step S320), and the process ends.
