[0016] AV information played back in the present embodiment is received from outside and once recorded in the electronic device 100, is output from the AV information output unit 110 to the playback control unit 160, and the playback unit 1

It will be described as being played at 70.

[0017] It should be noted that the reproduced AV information is not limited to the one received by an external force, but may be one stored in an external storage medium.

[0018] Scene switching information detection section 120 detects the scene switching timing of the scene constituting the AV information input to playback control section 160, and outputs the scene switching information to scene switching information recording section 130.

[0019] Here, the scene switching position indicated by the scene switching information is specifically the chapter that constitutes the video when the AV information reproduced by the reproduction unit 170 via the reproduction control unit 160 is movie information. The position which divides is mentioned.

Specifically, the scene switching information detected by the scene switching information detection unit 120 is

If the AV information is video data such as TV, the position of the TV program main part CM, or if it is a TV program drama, detect the moment when the scene changes in the same drama, and externally detect it as a scene switching signal Output. [0021] It should be noted that this scene switching detection uses, for example, a method of detecting using, for example, a moment when the sound is switched to a monaural sound. In addition, this scene switching detection uses a method such as sampling a time-series frame image from the target video and detecting it using the amount of change in luminance between adjacent frame images or the amount of change in luminance in units of frames. The

The scene switching information recording unit 130 records scene switching information indicating the scene switching position detected by the scene switching information detecting unit 120.

FIG. 2 shows a scene switching information recording unit 1 of electronic device 100 according to Embodiment 1 of the present invention.

FIG. 30 is a block diagram illustrating an example of a configuration of 30.

As shown in FIG. 2, the scene switching information recording unit 130 counts and outputs the system time (system clock or the like) of the system in the electronic device 100, and the counter 1

32, an index unit 133, a storage unit 134, and a clock output unit 135 that outputs time information.

[0025] The system timer 131 outputs the time information of the electronic device 100 to the storage unit 134 corresponding to the AV information to be reproduced, and also to the index unit 133, the clock output unit 135, and the interruption information holding unit 150. .

The counter 132 counts a scene switching signal that is also input from the scene switching information recording unit 130 (here, the scene switching information detection unit 120), and outputs the counted scene switching signal to the storage unit 134.

[0027] The index unit 133 generates an index indicating the current reproduction position of the AV information with respect to time information input corresponding to the reproduced AV information, and associates the index with the time information to the storage unit 134. Output.

The storage unit 134 includes a counter value from the counter 132, and time information from the system timer 131.

The index is input from the index unit 133, and the scene switching position information is stored using these.

[0029] Specifically, when the counter value is input, that is, when the counter value is updated, the storage unit 134 associates the updated counter value with the time information and index at that time. Recorded as scene switching position information. Here, the storage unit 134 Position information “scene switching position # 1,” “scene switching position # 2,” and “scene switching position # 3” are stored. It should be noted that the scene switching position information having time information corresponding to the stored counter value and the reproduction time of the AV information, here, the AV information is output from the AV information output unit 110 and passed through the reproduction control unit 160. Force generated when being played back by the playback unit 170 is not limited to this. For example, the reproduction control unit 160 may be created and stored in advance before the AV information output unit 110 is controlled and reproduced by the reproduction unit 170.

[0030] Further, the storage unit 134 outputs the stored scene switching position information to the interruption information holding unit 150 as information indicating the reproduction interruption position in response to an input from the interruption information holding unit 150 that has received the reproduction interruption instruction. To do.

The clock output unit 135 outputs the time information of the system timer 131 to the outside, here, the reproduction control unit 160 in response to the input of the reproduction instruction including the resumption of reproduction from the input unit 140.

[0032] The input unit 140 inputs an instruction from the user, and the input instruction is used as instruction information, the scene switching information recording unit 130, the interruption information holding unit 150, and the reproduction control unit 1

Output to 60.

[0033] Here, the input unit 140 gives a reproduction instruction including resumption of reproduction of AV information, a reproduction position selection instruction when there are a plurality of reproduction resumption target positions when instructing reproduction reproduction of AV information, and reproduction. The AV information interruption instruction etc. is input, and the instruction information corresponding to this input is output.

For example, when an instruction related to a reproduction instruction including resumption of reproduction is input to the input unit 140, the corresponding instruction information is output to the reproduction control unit 160. Also, when an instruction to interrupt playback of AV information being played back is input, the input unit 140 outputs an interrupt instruction to the scene switching information recording unit 130, the interrupt information holding unit 150, and the playback control unit 160.

[0035] The interruption information holding unit 150 is based on the time information input from the system timer 131 of the scene switching information recording unit 130 and the input instruction information from the user input from the input unit 140. In particular, the reproduction interruption state of AV information is maintained.

Specifically, the interruption information holding unit 150 receives an input from the outside, in this case, a reproduction interruption instruction from the input unit 140, and at the time of receiving the reproduction interruption instruction, The value of the time information input from is saved as the playback interruption time.

[0037] In addition, the interruption information holding unit 150 receives a reproduction interruption instruction from the outside (here, the input unit 140), and when receiving the reproduction interruption instruction, the interruption information holding unit 150 stores the storage unit 134 of the scene switching information recording unit 130. In addition, the switching position information related to the position of the AV information where the reproduction was interrupted is read and stored as the reproduction interruption position.

[0038] The scene switching position information includes an index of the switched scene and time information corresponding to the reproduction time of the AV information. With this configuration, when the playback is interrupted, the interruption information holding unit 150 acquires the scene switching position information from the storage unit 134. Using this information, the position of the AV information being reproduced via the reproduction control unit 160 is calculated in the scene, and this is stored as the reproduction interruption position together with the reproduction interruption time.

[0039] For example, the interruption state holding unit 150 reads the scene switching position information # 1, # 2, and # 3 from the storage unit 134 at the time when the reproduction interruption instruction is received, thereby including the point of interruption. The scene switching position information when the scene is switched to is acquired.

[0040] By making the interruption time correspond to the time information included in the acquired scene switching position information, the interruption information holding unit 150 can detect the reproduction interruption position C in the predetermined scene and save it. can do.

[0041] The playback control unit 160 indicates the user input instruction information from the input unit 140, the scene switching information from the scene switching information recording unit 130, and the interruption state of the electronic device 100 from the interruption information holding unit 150. Controls playback and interruption of AV information using information (playback interruption time).

[0042] The playback control unit 160, in particular, when an instruction to resume playback of the interrupted AV information is input from the input unit 140, the scene switching information and interrupt information holding unit 150 from the scene switching information recording unit 130. The information indicating the interruption state of the electronic device 100 from (the reproduction interruption time and the reproduction interruption position) is used to control the reproduction restart position of the AV information, and the control information is sent to the AV output unit 110 using the reproduction resume position. The AV information is played back by the playback unit 170.

In particular, the playback control unit 160 includes a comparison unit 161 and a playback restart position determination unit 162.

[0044] Comparison unit 161 determines time from the interruption of AV information to playback in electronic device 100. By doing so, it is determined whether or not the viewing time interval can evoke the contents when interrupted during playback. Specifically, when an instruction to resume playback is input, the comparison unit 161 displays the current time indicated by the time information input via the clock output unit 135 and the playback suspension time (interruption time from the suspension information holding unit 150). Read the status information), calculate the difference value, and determine the threshold value. This determination result is output to the reproduction restart position determination unit 162.

[0045] The playback restart position determination unit 162 determines a playback restart position corresponding to the viewing interval of the AV information by determining the playback restart position based on the comparison determination in the comparison unit 161.

Here, the playback restart position determination unit 162 selects and determines the playback restart position corresponding to the viewing interval from the playback interrupt time and the scene switching position before the interrupt.

Here, the selection operation of the scene switching position determined as the playback restart position will be described with reference to FIG.

FIG. 3 is a schematic diagram for explaining the operation of detecting the playback position of the electronic device according to Embodiment 1 of the present invention.

[0049] As shown in FIG. 3, when a reproduction resumption instruction is input, the reproduction resumption position determination unit 162 obtains a reproduction interruption time T and a reproduction interruption position C from the interruption information holding unit 150 as a reproduction position of AV information. , And the scene switching position information is read from the storage unit 134 of the scene switching information recording unit 130.

[0050] Specifically, if the scene switching position (for example, # 1) up to the scene including the playback interruption position C is i, the playback restart position determination unit 162 switches between the scene switching position i and the previous scene switching. Detect positions i 1, 1-2, in.

[0051] In this way, the playback restart position determination unit 162 switches the playback interrupt position C corresponding to the read playback interrupt time T and the switching position i of the scene including the playback portion of the playback interrupt position C (playback interrupt position C). The scene switching position i) immediately before and the scene switching positions i 1, i 2,..., In before the scene switching position are detected as positions to be resumed.

[0052] Using the reproduction resumption target position detected in this manner, reproduction resumption position determination unit 162 determines the reproduction resumption position according to the comparison determination result input from comparison unit 161. Here, when the viewing interval is the shortest, the playback restart position determination unit 162 The resumption position is set as the reproduction interruption position c, and scene switching positions i, i1, i2,.

[0053] Upon receiving this determination, the playback control unit 160 outputs control information to the AV information output unit 110 so that playback is resumed from the determined playback restart position. Play with 70.

Note that the reproduction restart position detected by the reproduction restart position determination unit 162 may be determined by an input instruction from the input unit 140. In this case, the playback control unit 160 causes the display unit 171 of the playback unit 170 to display the playback resume target position (playback interruption position C, scene switching position i, i 1, i 2) detected by the playback position determination unit 162. Control.

[0055] This makes it possible to adaptively select the playback resumption position in accordance with the storage state of the AV information content of the user, and to easily awaken the content of the already viewed AV information.

[0056] The reproduction unit 170 reproduces the AV information input from the reproduction control unit 160 and is viewed by the user.

[0057] The reproduction unit 170 includes a display unit 171 that displays video as AV information, that is, a moving image, and an audio reproduction unit 172 that outputs audio. The reproduction unit 170 is controlled by the reproduction control unit 160 to obtain AV information. Play video, audio corresponding to the video, music, etc.

Here, the operation of determining the playback restart position of electronic device 100 will be described.

[0059] FIG. 4 is a flowchart for explaining an operation of determining the playback restart position of the electronic device according to Embodiment 1 of the present invention. Note that here, after the AV information has already been played back on the electronic device 100 (see FIG. 1) and the playback is interrupted at the time T, the user at the time T

1 2

A description will be given on the assumption that reproduction restart has been instructed. It is assumed that the scene switching position i has been played back when playback is interrupted at this time T. In other words, it is assumed that playback has been interrupted in the AV information V and the scene switched at the scene switching position i. Referring to FIG. 3 for this state, the reproduction interruption position of the AV information corresponding to the time T when reproduction is interrupted is C.

[0060] At this time, since the interruption instruction is input from the input unit 140, the interruption information holding unit 150 When the reproduction interruption instruction is received from the input unit 140, the value of the time information input from the system timer 131 is saved as the reproduction interruption time, and the reproduction interruption position C of the AV information is saved.

When the playback resumption instruction is output from the input unit 140, the playback resumption instruction is input to the playback control unit 160 and to the clock output unit 135 of the scene switching information recording unit 130. When the reproduction restart instruction is input to the clock output unit 135, the clock output unit 135 outputs time information to the comparison unit 161 of the reproduction control unit 160.

Thereby, in the reproduction control unit 160, the comparison unit 161 acquires the time information from the scene switching information recording unit 130 as the current time T.

2

[0063] Also, the playback control unit 160 receives the playback restart instruction from the input unit 140, and acquires the interrupt status information, here, the playback interrupt time T from the interrupt information holding unit 150.

[0064] After acquiring these pieces of information, in step S201, in the playback control unit 160, the comparison unit calculates the difference between the acquired current time T, the playback interruption time T, which is the time of interruption, and the prediction value.

twenty one

Compare with the value N, which is the threshold value for the viewing interval that was set.

Specifically, in step S201, the difference value, that is, the current time T one playback interruption time

2

T is compared with the threshold value N. If the difference value is smaller than the threshold value N, the process proceeds to step S202. If the difference value is greater than or equal to the threshold value N, the process proceeds to step S203.

[0066] In step S202, in the reproduction control unit 160, the reproduction resumption position determination unit 162 determines that the viewing interval is not so long that the user forgets the content of the portion where the reproduction was interrupted, and interrupts the reproduction. The process ends with the position corresponding to time T as the playback resume position.

[0067] That is, if the current time T—the playback interruption time T is smaller than the threshold value N, it is played back.

twenty one

In the AV information, the position corresponding to the playback interruption time T is determined as the playback restart position, and

2

The raw control unit 160 controls AV information reproduction.

[0068] In step S203, in the reproduction control unit 160, the reproduction resumption position determination unit 162 assumes that the viewing interval is an interval that is free enough for the user to forget the content of the reproduction interruption, and the reproduction interruption time The process ends with the scene switching position i before T as the playback restart position.

[0069] That is, if the current time T and one playback interruption time T is equal to or greater than the threshold value N, playback is performed. Scene switching for scenes where the AV information includes the position corresponding to the playback interruption time T

2

Position i is determined as the playback resume position, and playback control section 160 controls playback of AV information.

It should be noted that the playback restart position in playback restart position determination unit 162 is determined by inputting an instruction from playback unit 160 to input unit 140 to playback interrupt position in AV information corresponding to playback interrupt time T. It may be determined by selecting C, scene switching position i and force. At this time, the playback control unit 160 controls the display unit 171 to display the playback stop position C and the scene switching position i in the AV information corresponding to the playback stop time T detected by the playback resume position determination unit 162.

[0071] It should be noted that AV information playback control in playback control section 160 is performed using playback stop position acquired from interrupt information holding section 150 when playback stop time T is determined as the restart position. AV information is played from the position corresponding to. When the scene switching position i is determined as the playback position, the playback control unit 160 uses the scene switching position i to play back AV information from the corresponding scene position i.

In this way, electronic device 100 according to the present embodiment capable of reproducing AV information includes scene switching information detection unit 120 that detects scene switching position i of a scene that constitutes AV information, and detected scene switching. A scene switching information recording unit 130 that records the position i together with the playback position of the AV information to be played back, a playback unit 170 that plays back the AV information, an instruction to interrupt the AV information being played back, or the AV information that was interrupted An input unit 140 for inputting a resumption instruction for the video, an interruption information holding unit 150 for holding interruption information of AV information including the reproduction interruption time T when the interruption instruction is input and the interruption instruction is input, and a scene A reproduction control unit 160 that controls reproduction of AV information in the reproduction unit 170 using information input from the switching information recording unit 130, the input unit 140, and the interruption information holding unit 150 is provided.

[0073] When a restart instruction is input from the input unit 140, the playback control unit 160, based on the difference between the restart instruction time (for example, time T) when the restart instruction is input and the playback interruption time T,

twenty one

Select one of the playback stop position of AV information as the playback stop position corresponding to the playback stop time in AV information and the scene switching position i recorded before the playback stop position. Play AV information. [0074] The playback start position is determined in advance by, for example, the difference between the time T at which playback of AV information is interrupted and the time T at which restart is instructed by the playback restart position determination unit 162 of the playback control unit 160.

1 2

Compared to a threshold indicating the time spent. As a result of this comparison, the playback restart position is determined as the playback interrupt position in the AV information, or the scene switching position before the playback interrupt position, depending on whether it is smaller than the threshold or greater than the threshold. Or In addition, as a target of this playback restart position, the playback restart position determination unit 162 controls playback display of the playback interruption position and the scene switching position before the playback interruption position on the display unit 171 of the playback unit 170 and lists them. The user is made to select via the input unit 140. The scene switching position i includes at least a switching position immediately before the playback interruption position among a switching position immediately before the playback interruption position and a plurality of switching positions immediately before the playback interruption position.

Accordingly, it is possible to adaptively control using the scene switching information and the interruption state information in which the reproduction restart position of the AV information is simply input by the user. In other words, even if the viewing interval when the playback was interrupted before resuming playback is long, it is possible to efficiently recall the user's memory by automatically determining the playback restart position according to the interval or by letting the user select it. Can reduce the burden on the user when resuming playback.

[0076] In other words, even when the AV information viewing interval (AV information playback interruption Z restart interval) is long, there is no need to rewind the AV information to a position where the content can be aroused when playback is restarted. Therefore, it is possible to allow users to view the AV information by inducing content efficiently.

[0077] It should be noted that the playback control position of the playback control unit 160 is determined by selecting the force with the playback interruption position C and the scene switching position i immediately before the playback interruption position C with reference to the playback interruption position C. Not only this, but also any scene switching position force can be selected and determined as long as the target is the scene switching position! /.

[0078] For example, the playback restart position determination unit 162 may set the scene switching positions i-1, i2, ..., in before the playback interruption position C as the target of the playback restart position. At this time, the comparison unit 161 selects threshold values corresponding to a plurality of scene switching positions so that the playback restart position determination unit 162 appropriately selects a plurality of scene switching positions before the playback interruption position as the playback restart position. Judgment shall be made. [0079] Also, a scene switching position indicated by a plurality of continuous scene switching information detected by the scene switching information detection unit 120 with respect to AV information to be reproduced is configured as one chapter. In this case, the playback restart position determination unit 162 of the playback control unit 160 includes the chapter as the target of the playback restart position, and uses the scene switching position i including the playback interruption position C as a reference, and the scene switching position and the chapter. , Make it the target of the playback resume position. This operation will be described below as a modified example.

[0080] (Modification)

[0081] In this case, the playback restart position determination unit 162 of the electronic device assumes that a plurality of continuous scene switching positions detected for the AV information to be played back constitute one chapter, Chapters are included.

Here, with the scene switching position i including the playback interruption position C as a reference, the scene switching position and the chapter are set as the playback restart position targets.

Therefore, the scene switching information recorded by the scene switching information recording unit 130 is managed in a hierarchical structure when the scene changes greatly and when it changes slightly. For example, a program change is regarded as a large scene change, that is, a chapter change, and a scene change in the program is regarded as a scene change constituting the chapter and managed. Here, the position in the AV information is represented by (j, i) as a set of a large scene unit j and a small scene unit i.

[0084] Here, as in FIG. 4, it is assumed that AV information has already been played back on the electronic device, and playback has been interrupted at time T, and then the user has instructed playback restart at time T.

2

The It is assumed that the scene switching position i has been played back when playback is interrupted at this time τ. In other words, in the AV information, playback is interrupted in the scene switched at the scene switching position i. If this state is referenced with reference to FIG. 3, the reproduction interruption position of the AV information corresponding to the time T when reproduction was interrupted is C.

At this time, since the interruption instruction is input from the input unit 140, the interruption information holding unit 150 is input from the system timer 131 when the reproduction interruption instruction is received from the input unit 140. The value of the time information is stored as the playback interruption time, that is, the playback interruption position of the AV information.

2

[0088] Also, the playback control unit 160 receives a playback restart instruction from the input unit 140, and receives playback status information from the interruption information holding unit 150, here, playback corresponding to the playback interruption time T and the playback interruption time T. Get the interrupt position.

[0089] After acquiring these pieces of information, in step S301, in the playback control unit 160, the comparison unit 161 sets the difference value between the acquired current time T and the playback interruption time T, which is the time of interruption.

twenty one

Compared with a preset value N1 which is a threshold value of the viewing interval.

[0090] Specifically, in step S301, the difference value, that is, the current time T one playback interruption time

2

T is compared with the threshold value N1, and if the difference value is smaller than the threshold value N1, the process proceeds to step S302. If the difference value is greater than or equal to the threshold value N1, the process proceeds to step S303.

[0091] In step S302, in the playback control unit 160, the playback restart position determination unit 162 ends the processing with the scene switching position (j, i-1) as the playback restart position.

That is, when the current time T—the playback interruption time T is smaller than the threshold value N, playback is performed.

twenty one

In the AV information, the position corresponding to the scene switching position (j, i 1) is determined as the reproduction restart position, and the reproduction control unit 160 controls the reproduction of AV information.

[0093] In step S303, in the playback control unit 160, the playback resumption position determination unit 162 has passed the time so long that the content before the portion where playback was interrupted by the user whose viewing interval is long is forgotten. The scene switching position (j 1, i) is set as the playback restart position, and the process ends.

[0094] That is, if the current time T one playback interruption time T is equal to or greater than the threshold N1, playback is not performed.

Scene switching position (j) that indicates a chapter that includes the interrupted position in the AV information. 1, i) is determined as the reproduction restart position, and the reproduction control unit 160 controls the reproduction of AV information.

It should be noted that the reproduction resumption position in reproduction resumption position determination unit 162 is determined by inputting an instruction from reproduction unit 160 to input unit 140 through reproduction interruption position in AV information corresponding to reproduction interruption time T. It may be determined by selecting C and the scene switching position (j, i−1), (j−1, i). At this time, the playback control unit 160, the playback interruption position C in the AV information corresponding to the playback interruption time T detected by the playback resume position determination unit 162, the scene switching position (j, i 1), (j-1 , i) are controlled on the display unit 171.

[0096] It should be noted that AV information playback control in playback control section 160 is performed by using playback stop position acquired from interrupt information holding section 150 when playback stop time T is determined as the restart position. AV information is played from the position corresponding to. In addition, when the scene switching position (for example, (j, i 1), (j-1, i)) is determined as the playback position, the playback control unit 160 may select the scene switching position (for example, (j, i) — Use 1) and (j-1, i)) to play back the position force AV information corresponding to scene switching position i.

[0097] This enables adaptive control using scene switching information and interruption status information in which the playback restart position of AV information is simply input by the user. Even when the interval is long, the user's memory can be recalled efficiently, and the burden on the user when resuming playback can be reduced.

[0098] In particular, in the modified example, in addition to the scene switching position indicating the beginning of the scene including the interrupted position, the beginning of the chapter including the scene can be selected and determined as the playback restart position. As a result, even when the viewing interval of AV information played back on the electronic device 100 is long, the playback restart position corresponding to the position where the user can arouse the content can be selected and determined, or You can let the user choose.

[0099] The embodiment of the present invention has been described above.
