[0010] Hereinafter, embodiments of the video management system according to the present invention will be described with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, the components in the following embodiments include those that are easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0011] Figure 1 is a schematic diagram showing an example of the video management system 100 according to this embodiment. Figure 2 is a functional block diagram showing an example of the video management system 100 according to this embodiment. As shown in Figures 1 and 2, the video management system 100 comprises a terminal device 10, a drive recorder 20, and a management device 30.

[0012] The terminal device 10 is capable of transmitting unique identification information via wireless signals. The terminal device 10 is a device that can be carried and used by a user riding in a vehicle. Examples of the terminal device 10 include portable information and communication terminals such as smartphones and tablets.

[0013] The terminal device 10 includes an input unit 11, a display unit 12, a communication unit (terminal-side communication unit) 13, a storage unit 14, and a control unit 15.

[0014] The input unit 11 is capable of performing a predetermined input operation for inputting information. The input unit 11 outputs an instruction signal to the control unit 15 in response to the input operation. As the input unit 11, for example, an input device such as a keyboard or a touch panel is used. In addition to or instead of these, buttons, levers, dials, switches, or other input devices may be used as the input unit 11. The input unit 11 outputs an instruction signal corresponding to a predetermined input operation.

[0015] The display unit 12 is a display panel such as a liquid crystal panel, and displays various information including characters and images.

[0016] The communication unit 13 communicates information with the drive recorder 20 and the management device 30. The communication unit 13 can perform wireless communication with the drive recorder 20, for example, by a short-range wireless signal.

[0017] The storage unit 14 stores various information. The storage unit 14 has a storage such as a hard disk drive or a solid state drive. In addition, an external storage medium such as a removable disk may be used as the storage unit 14. The storage unit 14 stores the operating system of the terminal device 10, various applications, programs, and data for controlling the operations of the input unit 11, the display unit 12, and the communication unit 13. The storage unit 14 stores an application for setting identification information with the drive recorder 20.

[0018] The control unit 15 controls each of the input unit 11, the display unit 12, the communication unit 13, and the storage unit 14. The control unit 15 has a processing device such as a CPU (Central Processing Unit) and a storage device such as a RAM (Random Access Memory) or a ROM (Read Only Memory). As shown in FIG. 2, the control unit 15 has an authentication processing unit 51 and a communication control unit 52.

[0019] The authentication processing unit 51 performs authentication operations such as pairing with the drive recorder 20. The authentication operations include operations to obtain authentication information from the drive recorder 20, which will be described later. The authentication processing unit 51 stores the obtained authentication information in the storage unit 14.

[0020] The communication control unit 52 causes the communication unit 13 to send and receive information. The communication control unit 52 causes the communication unit 13 to transmit the authentication information stored in the storage unit 14 as identification information for the terminal device 10. When transmitting authentication information, the communication control unit 52 can cause the communication unit 13 to transmit it using a short-range wireless signal, for example, by a transmission method such as broadcast transmission.

[0021] Furthermore, the terminal device 10 can also be used as a playback device 40, which will be described later. When the terminal device 10 is used as a playback device 40, it has a configuration for making playback requests (described later) to the management device 30.

[0022] The drive recorder 20 is installed in the vehicle. The drive recorder 20 has a shooting unit 21, an input unit 22, a display unit 23, a communication unit (recorder-side communication unit) 24, a storage unit 25, and a control unit 26.

[0023] The camera unit 21 captures images of the interior and exterior of the vehicle and generates video data. The camera unit 21 can be set to generate video data, for example, at predetermined intervals. The camera unit 21 stores the generated video data in the storage unit 25.

[0024] The input unit 22 is capable of performing predetermined input operations for inputting information. The input unit 22 outputs instruction signals to the control unit 26 in response to the input operations. For example, the input unit 22 can be an input device such as a keyboard or touch panel. In addition to these, or in place of these, buttons, levers, dials, switches, or other input devices may be used as the input unit 22. The input unit 22 outputs instruction signals in response to predetermined input operations.

[0025] The display unit 23 displays information such as images and text. The display unit 23 may be, for example, a liquid crystal panel.

[0026] The communication unit 24 performs wireless communication with the terminal device 10 and the management device 30. The communication unit 24 can perform wireless communication with the terminal device 10, for example, using short-range wireless signals. The communication unit 24 can detect the strength of short-range wireless signals. When the communication unit 24 detects the strength of short-range wireless signals, it outputs the detected strength to the control unit 26.

[0027] The storage unit 25 stores various types of information. The storage unit 25 has storage such as a hard disk drive or a solid-state drive. Alternatively, an external storage medium such as a removable disk may be used as the storage unit 25. The storage unit 25 stores the operating system of the drive recorder 20, as well as various applications, programs, and data for controlling the operation of the shooting unit 21 and the communication unit 24. The storage unit 25 stores video data generated by the shooting unit 21. The storage unit 25 stores identification information contained in the wireless signals received by the communication unit 24.

[0028] The control unit 26 controls the imaging unit 21, the communication unit 24, and the storage unit 25. The control unit 26 has a processing unit such as a CPU and a storage device such as RAM or ROM. The control unit 26 has a setting control unit 61, an extraction unit 62, a generation unit 63, and a communication control unit 64.

[0029] The configuration control unit 61 sets identification information with the terminal device 10. The configuration control unit 61 can set authentication information with each terminal device 10 as identification information. The configuration control unit 61 controls the authentication operation with the terminal device 10. During the authentication operation, the configuration control unit 61 can display, for example, a password on the display unit 23.

[0030] The extraction unit 62 acquires identification information from the short-range radio signal received by the communication unit 24. From the acquired identification information, the extraction unit 62 extracts identification information from the terminal device 10 located inside the vehicle. When the communication unit 24 receives a short-range radio signal from the terminal device 10 located outside the vehicle, the received signal strength is lower than when the short-range radio signal is received from the terminal device 10 inside the vehicle. Therefore, the extraction unit 62 can extract identification information from the terminal device 10 inside the vehicle based on the strength of the received short-range radio signal. For example, if the strength of the received short-range radio signal is above a predetermined threshold, the extraction unit 62 extracts the identification information contained in the short-range radio signal as identification information from the terminal device 10 inside the vehicle. Also, if the strength of the received short-range radio signal is below a predetermined threshold, the extraction unit 62 does not extract the identification information contained in the short-range radio signal.

[0031] The generation unit 63 generates correspondence data by associating the video data generated by the shooting unit 21 with the identification information extracted by the extraction unit 62. The generation unit 63 generates correspondence data for each video data.

[0032] The communication control unit 64 causes the corresponding data generated by the generation unit 63 to be transmitted from the communication unit 24 to the management device 30.

[0033] The management device 30 manages the corresponding data generated by the generation unit 63. As part of managing the corresponding data, the management device 30 determines, for example, whether or not to allow playback in response to a playback request from the playback device 40. The playback request is information requesting playback of the video data contained in the corresponding data. The playback device 40 can be, for example, the terminal device 10 described above, but it is not limited to the terminal device 10 and may be any other device that can communicate with the management device 30 and can play back video data. The management device 30 has a communication unit (management-side communication unit) 31, a storage unit 32, and a control unit 33.

[0034] The communication unit 31 performs wireless communication with the drive recorder 20 and the playback device 40. The communication unit 31 receives corresponding data contained in the wireless signal transmitted from the drive recorder 20. The communication unit 31 receives a playback request transmitted from the playback device 40.

[0035] The storage unit 32 stores various types of information. The storage unit 32 has storage such as a hard disk drive or a solid-state drive. Alternatively, an external storage medium such as a removable disk may be used as the storage unit 32. The storage unit 32 stores the operating system of the management device 30, various applications, programs, and data for controlling the operation of the communication unit 31 and the operation of the control unit 33. The storage unit 32 also stores corresponding data contained in the wireless signals received by the communication unit 31.

[0036] The control unit 33 controls the communication unit 31 and the storage unit 32. The control unit 33 has a processing unit such as a CPU and a storage device such as RAM or ROM. The control unit 33 has a storage processing unit 71 and a playback processing unit 72.

[0037] The memory processing unit 71 stores the corresponding data received by the communication unit 31 in the memory unit 32.

[0038] When the playback processing unit 72 receives a video data playback request from the communication unit 31 for corresponding data stored in the storage unit 32, it determines whether the video data for which the playback request was received is included in the playback request. If the playback processing unit 72 determines that the video data for which the playback request was received is included in the playback request, it permits playback of the video data. In this case, the playback processing unit 72 has the communication unit 31 send permission information indicating that playback has been permitted as a request result to the playback device 40. If the playback processing unit 72 determines that the video data for which the playback request was received is not included in the playback request, it does not permit playback of the video data. In this case, the playback processing unit 72 has the communication unit 31 send permission information indicating that playback is not permitted as a request result to the playback device 40.

[0039] Next, we will explain the operation flow of the video management system 100 configured as described above. Figures 3 to 6 show an example of the operation of the video management system 100.

[0040] First, the operation when setting authentication information between the terminal device 10 and the drive recorder 20 will be explained. As shown in Figure 3, when a predetermined operation for setting authentication information is performed on the input unit 22 of the drive recorder 20, the setting control unit 61 displays the password on the display unit 23 for a certain period of time. When the password is entered on the input unit 11 of the terminal device 10, the authentication processing unit 51 causes the password to be sent to the drive recorder 20.

[0041] When the drive recorder 20 receives a password transmitted from the terminal device 10, the setting control unit 61 determines whether the password is valid or not. If the setting control unit 61 determines that the password is valid, it causes the terminal device 10 to send authentication information.

[0042] When the terminal device 10 receives authentication information transmitted from the drive recorder 20, the authentication processing unit 51 stores the received authentication information in the storage unit 14. The authentication processing unit 51 sets the authentication information stored in the storage unit 14 as identification information. Note that the authentication method between the terminal device 10 and the drive recorder 20 is not limited to the above method and may be other methods.

[0043] Next, we will explain the operation when the drive recorder 20 generates corresponding data. First, we will explain the case where users U1 and U2, who possess terminal devices 10 with identification information I1 and I2 set, are in a vehicle R equipped with the drive recorder 20.

[0044] In the drive recorder 20, the shooting unit 21 captures at least one of the interior and exterior of the vehicle and generates video data at predetermined intervals. The shooting unit 21 generates video data corresponding to the time. The shooting unit 21 stores the generated video data in the storage unit 25. In the example shown in Figure 4, the shooting unit 21 generates video data D1, D2, and D3.

[0045] In the terminal device 10 owned by users U1 and U2, the communication control unit 52 causes the drive recorder 20 to transmit short-range wireless signals S1 and S2 containing identification information I1 and I2 via broadcast transmission. The communication control unit 52 causes the short-range wireless signals containing the identification information to be transmitted, for example, at intervals shorter than the predetermined time for video data to be generated.

[0046] In the drive recorder 20, the communication unit 24 receives short-range wireless signals S1 and S2 transmitted from the terminal device 10 and detects the strength of the short-range wireless signals S1 and S2. The communication unit 24 outputs the received short-range wireless signals S1 and S2 and their detected strengths to the control unit 26. The extraction unit 62 also acquires identification information I1 and I2 based on the received short-range wireless signals S1 and S2.

[0047] The extraction unit 62 extracts identification information from the terminal device 10 located inside the vehicle R from the acquired identification information I1 and I2. In this case, if the intensity of the short-range radio signals S1 and S2 received by the communication unit 24 is above a predetermined threshold, the extraction unit 62 extracts the identification information contained in the short-range radio signals S1 and S2 as identification information from the terminal device 10 located inside the vehicle. On the other hand, if the intensity of the short-range radio signals S1 and S2 received by the communication unit 24 is below a predetermined threshold, the extraction unit 62 does not extract the identification information contained in the short-range radio signals S1 and S2. In the example shown in Figure 4, since the intensity of the short-range radio signals S1 and S2 is above a predetermined threshold, the extraction unit 62 extracts the identification information I1 and I2 contained in the short-range radio signals S1 and S2 as identification information from the terminal device 10 located inside the vehicle M.

[0048] The generation unit 63 generates corresponding data T1, T2, and T3 by associating the video data D1, D2, and D3 generated by the shooting unit 21 with the identification information I1 and I2 extracted by the extraction unit 62. The generation unit 63 generates corresponding data for each of the video data D1, D2, and D3. For example, the generation unit 63 generates corresponding data by associating the identification information I1 and I2 extracted during the generation period from the start to the completion of the generation of the video data D1, D2, and D3 with the video data D1, D2, and D3. As a result, corresponding data T1, T2, and T3 are generated in which the identification information I1 and I2 of users U1 and U2 who were in the vehicle R during the generation period of the video data D1, D2, and D3 are associated with the video data D1, D2, and D3.

[0049] Here, we will explain a case where, for example, after video data D3 is generated, one of the two users U1 and U2, user U2, gets out of the vehicle, and after user U2 gets out, video data D4 and D5 are generated by the recording unit 21. In this case, as shown in Figure 5, a short-range wireless signal S1 containing identification information I1 is transmitted from the terminal device 10 held by user U1. In the drive recorder 20, the communication unit 24 receives the short-range wireless signal S1 transmitted from the terminal device 10. The extraction unit 62 acquires the identification information I1 based on the received short-range wireless signal S1 and extracts the acquired identification information I1 as identification information from the terminal device 10 located inside the vehicle R. The generation unit 63 generates corresponding data T4 and T5, which associate the identification information I1 with the video data D4 and D5. As a result, corresponding data T4 and T5 are generated, which associate the identification information I1 of user U1, who was in the vehicle M during the generation period of video data D4 and D5, with the video data D4 and D5.

[0050] The communication control unit 64 transmits the corresponding data T1 to T5 generated by the generation unit 63 to the management device 30.

[0051] In the management device 30, the communication unit 31 receives the transmitted corresponding data T1 to T5. The storage processing unit 71 stores the corresponding data T1 to T5 received by the communication unit 31 in the storage unit 32. The corresponding data T to T5 is stored in the storage unit 32.

[0052] Next, the operation when playback is performed will be explained. By performing a predetermined operation on the playback device 40, a playback request is sent to the management device 30. Figure 6 shows an example in which users U1 and U2 send playback requests for video data D1 and D4 to the management device 30 from different playback devices 40, respectively.

[0053] In the management device 30, the communication unit 31 receives a playback request. When the playback processing unit 72 receives a playback request in the communication unit 31, it determines whether or not the identification information associated with the video data for which the playback request was received is included in the playback request. If the playback processing unit 72 determines that the identification information associated with the video data for which the playback request was received is included in the playback request, it permits playback of the video data. If the playback processing unit 72 determines that the identification information associated with the video data for which the playback request was received is not included in the playback request, it does not permit playback of the video data.

[0054] In the example shown in Figure 6, the playback request from user U1 includes identification information I1. The video data D1 that receives the playback request is associated with user U1's identification information I1. Therefore, in the management device 30, the playback processing unit 72 determines that the video data D1 and D4 that received the playback request from user U1 are associated with user U1's identification information I1. In this case, the playback processing unit 72 permits the playback request for video data D1 and D4 from user U1. The playback processing unit 72 sends permission information as a request result to user U1's playback device 40, granting permission for playback. When user U1's playback device 40 receives the permission information, it downloads the video data D1 and D4 from the management device 30 based on the permission information and plays them.

[0055] In the example shown in Figure 6, the playback request from user U2 includes identification information I2. The video data D1 that was requested for playback is associated with user U2's identification information I2. Therefore, in the management device 30, the playback processing unit 72 determines that the video data D1 that was requested for playback is associated with user U2's identification information I2. In this case, the playback processing unit 72 permits the playback request for video data D1 from user U2. The playback processing unit 72 sends permission information as a request result to user U2's playback device 40, granting permission to play video data D1. When user U2's playback device 40 receives the permission information, it downloads and plays the video data D1 from the management device 30 based on the permission information.

[0056] On the other hand, the video data D4 is not associated with the user U2's identification information I2. Therefore, the playback processing unit 72 determines that the video data D4, for which a playback request has been received, is not associated with the user U2's identification information I2. In this case, the playback processing unit 72 does not permit the playback request for video data D4 from user U2. The playback processing unit 72 sends a disallowance message to user U2's terminal device 10 as a request result, indicating that playback of video data D4 is not permitted. When user U2's playback device 40 receives the disallowance message, it terminates processing without playing video data D4. Furthermore, by equipping the terminal device 10 with the functions of a playback device 40 as described above, it is also possible to use the terminal device 10 as a playback device 40.

[0057] Figures 7 to 9 are flowcharts illustrating an example of the operation of the video management system 100. Figure 7 shows the operation when setting authentication information between the terminal device 10 and the drive recorder 20. As shown in Figure 7, the terminal device 10 is configured to install an application for setting authentication information with the drive recorder 20 (step S101). In this state, when a user performs a predetermined operation on the input unit 22 of the drive recorder 20, the setting control unit 61 displays the password on the display unit 23 (step S102).

[0058] In terminal device 10, when the password displayed on the display unit 23 of the drive recorder 20 is entered into the input unit 11 and an operation to send the password is performed, the authentication processing unit 51 causes the communication unit 13 to send the password (step S103).

[0059] In the drive recorder 20, the communication unit 24 receives the transmitted password (step S104). The setting control unit 61 determines whether the received password is valid or not (step S105). If the setting control unit 61 determines that the password is valid (Yes in step S105), it causes the terminal device 10 to send authentication information as an authentication result (step S106). On the other hand, if the setting control unit 61 determines that the password is invalid (No in step S105), it causes the terminal device 10 to send information indicating that the password is invalid as an authentication result (step S107).

[0060] After the terminal device 10 sends a password to the drive recorder 20, the communication control unit 64 determines whether it has received an authentication result from the drive recorder 20 (step S108). If it determines that it has not received an authentication result (No. in step S108), the operation in step S108 is repeated.

[0061] If it is determined that an authentication result has been received (Yes in step S108), and the received authentication result is authentication information (Yes in step S109), the communication control unit 64 sets the received authentication information as identification information (step S110) and terminates the process. If the received authentication result is NG information (No in step S109), the communication control unit 64 skips the process in step S110 and terminates the process.

[0062] Figure 8 shows the operation of generating and storing corresponding data. As shown in Figure 8, in the terminal device 10, the communication control unit 52 causes the drive recorder 20 to transmit a short-range wireless signal containing identification information at predetermined intervals (step S201).

[0063] In the drive recorder 20, the shooting unit 21 captures images of the interior and exterior of the vehicle, generates video data at predetermined intervals, and stores it in the storage unit 25 (step S202).

[0064] Furthermore, the communication unit 24 receives a short-range wireless signal transmitted from the terminal device 10 (step S203). Steps S202 and S203 may be started in any order, or they may be started at the same time. The extraction unit 62 acquires identification information from the short-range wireless signal (step S204) and extracts identification information from the terminal device 10 located inside the vehicle from the acquired identification information (step S205). The generation unit 63 generates correspondence data that associates the video data generated by the shooting unit 21 with the identification information extracted by the extraction unit 62 (step S206). The communication control unit 64 transmits the generated correspondence data to the management device 30 (step S207).

[0065] In the management device 30, the communication unit 31 receives the transmitted corresponding data (step S208). The storage processing unit 71 stores the received corresponding data in the storage unit 32 (step S209).

[0066] Figure 9 shows the operation when playing back video data included in the corresponding data. As shown in Figure 9, when a predetermined operation is performed on the playback device 40, a playback request with identification information is sent to the management device 30 (step S301).

[0067] In the management device 30, the communication unit 31 receives a playback request (step S302). When the playback processing unit 72 receives a playback request in the communication unit 31, it determines whether or not the identification information associated with the video data for which the playback request was received is included in the playback request (step S303). If the playback processing unit 72 determines that the identification information associated with the video data for which the playback request was received is included in the playback request (Yes in step S303), it sends permission information to the playback device 40 as a request result, indicating that playback of the video data is permitted (step S304). On the other hand, if the playback processing unit 72 determines that the identification information associated with the video data for which the playback request was received is not included in the playback request (No in step S303), it sends denial information to the playback device 40 as a request result, indicating that playback of the video data is not permitted (step S305).

[0068] In the playback device 40, after a playback request is sent, it is determined whether the request result sent from the management device 30 has been received (step S306). If it is determined that the request result has not been received from the management device 30 (No. in step S306), the operation in step S306 is repeated.

[0069] If the playback device 40 determines that it has received a request result from the management device 30 (Yes in step S306), and the received request result is permission information (Yes in step S307), the playback device 40 downloads and plays the video data from the management device 30 based on the received permission information (step S308). If the received request result is permission information (No in step S307), the playback device 40 skips step S308 and terminates processing.

[0070] As described above, the video management system 100 according to this embodiment is a video management system 100 comprising a plurality of terminal devices 10, a drive recorder 20 mounted on a vehicle R, and a management device 30, wherein the plurality of terminal devices 10 are capable of communicating with the drive recorder 20 and each has a communication unit 13 capable of transmitting a wireless signal containing unique identification information, the drive recorder 20 has a shooting unit 21 that shoots at least one of the inside and outside of the vehicle R and generates video data, a communication unit 24 that can communicate with the terminal devices 10 and the management device 30, and when it receives a wireless signal containing identification information from the plurality of terminal devices 10 The management device 30 includes an extraction unit 62 that extracts identification information of the terminal device 10 inside the vehicle R, and a generation unit 63 that generates corresponding data that associates the generated video data with the extracted identification information. The management device 30 includes a communication unit 31 that can communicate with the drive recorder 20 and the terminal device 10, a storage unit 32 that stores the corresponding data generated by the generation unit 63, and a playback processing unit 72 that, upon receiving a playback request that includes identification information, determines whether the identification information associated with the video data that is the target of the playback request matches the identification information included in the playback request, and if it determines that they match, permits the source of the playback request to play the video data.

[0071] In this configuration, correspondence data is generated that associates video data captured by the drive recorder 20 with the identification information of the user's terminal device 10 in the vehicle. When a request is made to play the video data, playback is permitted only if the identification information associated with the video data is included in the playback request. This prevents permission to play video data at the request of a user who is not in the vehicle. This makes it possible to appropriately protect the privacy of the vehicle's occupants.

[0072] In the video management system 100 according to this embodiment, the extraction unit 62 extracts identification information of the terminal device 10 inside the vehicle based on the strength of the received wireless signal. With this configuration, it is possible to detect with high accuracy whether or not the terminal device 10 is inside the vehicle. Therefore, it is possible to extract identification information of the terminal device 10 inside the vehicle with high accuracy.

[0073] In the video management system 100 according to this embodiment, the generation unit 63 generates video data at predetermined intervals and generates corresponding data for each generated video data. With this configuration, even if the status of the terminal device 10 located inside the vehicle changes, such as when a user possessing the terminal device 10 gets in or out of the vehicle, corresponding data can be generated in accordance with the change.

[0074] In the video management system 100 according to this embodiment, the identification information is authentication information that is individually assigned to the terminal device 10 by the drive recorder 20. With this configuration, since the authentication information assigned by the drive recorder 20 is used as identification information, the identification information of the terminal device 10 in the vehicle can be extracted with high accuracy.

[0075] The technical scope of the present invention is not limited to the embodiments described above, and modifications can be made as appropriate without departing from the spirit of the invention. For example, in the embodiments described above, a configuration in which the management device 30 is provided separately from the drive recorder 20 was given as an example, but the invention is not limited to this configuration.

[0076] Figure 10 shows the configuration of a modified video management system 100A. As shown in Figure 10, the video management system 100A comprises a terminal device 10 and a drive recorder 20A. The drive recorder 20A has the functions of the drive recorder 20 described in the above embodiment and the functions of the management device 30. In other words, the video management system 100A is configured such that the drive recorder 20A is equipped with a configuration corresponding to the management device 30. Specifically, a storage processing unit 71 and a playback processing unit 72A that perform the same processing as the storage processing unit 71 and playback processing unit 72 provided in the control unit 33 of the management device 30 in the above embodiment are provided in the control unit 26A of the drive recorder 20A.

[0077] In this configuration, the corresponding data generated by the drive recorder 20A is stored in the memory unit 25 of the drive recorder 20A under the control of the memory processing unit 71A of the control unit 26A. When playing back video data, the playback device 40 sends a playback request to the drive recorder 20A. The drive recorder 20A receives the playback request in the communication unit 24. The playback processing unit 72A determines whether the identification information associated with the video data for which the playback request was received is included in the playback request. If the playback processing unit 72A determines that the identification information associated with the video data for which the playback request was received is included in the playback request, it permits playback of the video data. If the playback processing unit 72A determines that the identification information associated with the video data for which the playback request was received is not included in the playback request, it does not permit playback of the video data. If playback is permitted, the playback processing unit 72A sends permission information to the playback device 40 as the request result, and if playback is not permitted, it sends permission information.

[0078] Thus, the video management system 100A is a video management system 100A that includes a plurality of terminal devices 10 and a drive recorder 20A mounted on a vehicle, wherein the plurality of terminal devices 10 are capable of communicating with the drive recorder 20A and each has a communication unit 13 capable of transmitting a wireless signal containing unique identification information, the drive recorder 20A includes a shooting unit 21 that shoots at least one of the inside and outside of the vehicle and generates video data, a communication unit 24 capable of communicating with the terminal devices 10, an extraction unit 62 that extracts the identification information of the terminal devices 10 inside the vehicle when it receives a wireless signal containing identification information from the plurality of terminal devices 10, a generation unit 63 that generates correspondence data that associates the generated video data with the extracted identification information, a storage unit 25 that stores the correspondence data generated by the generation unit 63, and a playback processing unit 72A that, when it receives a playback request containing identification information, determines whether the identification information associated with the video data that is the target of the playback request matches the identification information included in the playback request, and if it determines that they match, permits the source of the playback request to play the video data.

[0079] With this configuration, when a playback request for video data is received for the corresponding data, the drive recorder 20A is equipped with a function to determine whether or not the identification information associated with the requested video data is included in the playback request, and if it is determined that it is included, it permits playback of the video data. This eliminates the need to provide a separate management device, and the configuration of the video management system 100A can be made more compact. [Explanation of Symbols]
