The external recording device interface 7 controls data transmission / reception between the external recording device drive 71 and the CPU 1.

  FIG. 2 is a diagram showing a software configuration of the car navigation apparatus to which the content input / output control apparatus according to Embodiment 1 of the present invention is applied. The operating system of the car navigation device (hereinafter abbreviated as “car navigation OS”) is built on various device drivers for operating the hardware of the car navigation device (hereinafter referred to as “car navigation hardware”). Has been. On top of this car navigation OS, a navigation service 10, a Java application main body 11, a Java application execution unit (Java VM; Java Virtual Machine) 12, a Java application management unit 13, a Java application determination unit 14, and a Java application control unit 15 are provided. ing. The navigation service 10, the Java application main body 11, the Java application execution unit 12, the Java application management unit 13, the Java application determination unit 14, and the Java application control unit 15 are all configured by programs, and are executed by the CPU 1. A predetermined function is realized.

  The navigation service 10 provides a basic car navigation service such as displaying the current location or setting a destination and performing route guidance. The Java application main body 11 is content such as a game or a driving support program, for example. The Java application execution unit 12 corresponds to the content execution means of the present invention and provides an environment for executing the Java application. The Java application management unit 13 manages the entire operation of the Java application. The Java application determination unit 14 corresponds to the content determination unit of the present invention and determines the attribute of the Java application.

  The navigation service 10 includes a Java VM interface module 10a. In addition, the Java application execution unit 12 includes a navigation service interface module 12a. When the Java VM interface module 10a and the navigation service interface module 12a communicate with each other, the navigation service 10 and the Java application execution unit 12 operate in cooperation with each other. The JavaVM interface module 10a and the navigation service interface module 12a correspond to content input means, content output means, and external state acquisition means of the present invention.

  Next, the flow of processing when the Java application is executed in the content input / output control apparatus according to Embodiment 1 of the present invention will be described with reference to the flowchart shown in FIG. First, Java application input processing is performed. That is, it is connected to the Internet through a communication device 61 such as a mobile phone connected to the communication unit interface 6, a Java application is downloaded from a content provider (not shown), and is sent to the Java application determination unit 14. In addition to downloading from the Internet, the Java application can also be input from a recording medium such as a push distribution by DSRC or a CD or an SD card (Secure Digital memory card).

  Next, the Java application determination unit 14 executes a determination process for determining the attribute of the input Java application. In this determination process, the source of the Java application (URL (Uniform Resource Locator), site name, etc. of the site providing the Java application), name, size, and the like are acquired as the determination result. In the case of a signed Java application, the above-described information can be acquired by performing signature verification. In addition, if information about the Java application is prepared as a separate file, such as a Jad file of the MIDlet application, which is one of the Java application formats that can be executed on a small information terminal such as a mobile phone, the file is interpreted. By doing so, the information described above can be acquired. The signed Java application and the Jad file are technologies realized by an i-appli that can be used on the general Internet or a mobile phone, and thus description thereof is omitted. The Java application determination unit 14 transmits the acquired determination result to the Java application control unit 15 and also transmits the input Java application to the Java application execution unit 12. The Java application execution unit 12 executes the Java application and implements various functions.

  The Java application control unit 15 controls output information such as screen display and audio output of the Java application executed by the Java application execution unit 12 based on the determination result received from the Java application determination unit 14, or / and Input information such as operation input to the Java application by the user is controlled. At this time, the Java application control unit 15 switches control according to the state information acquired by the vehicle state acquisition process, for example, the vehicle speed information. The vehicle state acquisition process corresponds to the external state acquisition means of the present invention.

  Here, the process executed in the Java application control unit 15 will be described in more detail. The Java application control unit 15 first determines the range in which the Java application operates based on the Java application determination result sent from the Java application determination unit 14. Then, the operation of the Java application is permitted within the determined range, and if the range is exceeded, the operation of the Java application is restricted. As described above, in Java, as a method of setting the operation range for each application (specifically, for each signature applied to the Java application or for each place where the Java application main body 11 is stored), in Java, the type of Java application is included in the policy file. And a method of describing the permitted operations.

  FIG. 4 shows a description example of the policy file. This description example shows a case where the operation range is set according to the type of signature. In the case of a Java application signed by Provider A, permitted operations (access rights) are listed in {} following signed By Provider A. For example, the first line in {} is an access right prepared as standard in Java, and the data. Reading of the dat file is permitted.

  A unique description is added to this policy file to add functions that control output processing such as screen display and audio output, and input processing such as user input operations, which is a feature of the present invention. Is done. In the description example shown in FIG. 4, as a unique access right, com. melco. DisplayPermission has been added. In this description example, in the case of the Java application signed by Provider A, the screen can be displayed while the vehicle is stopped but the screen cannot be displayed while the vehicle is running. In the case of the Java application signed by Provider B, It means that the screen display while traveling is possible.

  Next, the Java application control unit 15 interprets the access right uniquely added to the policy file, and determines the operation range to be set according to the determination result obtained from the Java application determination unit 14. The policy file can be interpreted by the Java application execution unit 12 or the Java application management unit 13 and the interpretation result can be passed to the Java application control unit 15. In addition, the unique access right can be described in a file different from the policy file. In the policy file shown in FIG. 4, when the Java application control unit 15 acquires the current running state as the vehicle state and determines that the running application is running, if the running Java application is a Java application signed by Provider A, Stop display. Similarly, although not shown in the policy file shown in FIG. 4, if there is an access right for user input, the Java application control unit 15 controls to notify the Java application execution unit 12 of the input information.

The flow of processing for controlling whether to display the screen depending on whether the vehicle is running or stopped will be described with reference to the flowchart shown in FIG.
(1-1) A display process for displaying a screen is called from the Java application.
(1-2) The Java application execution unit 12 executes screen display processing for displaying the screen of the Java application, and notifies the Java application control unit 15 to execute control, that is, performs a control call. .
(1-3) In response to this control call, the Java application control unit 15 acquires the current traveling state as the vehicle state, and outputs Java application output control information that disables the Java screen display when traveling. Send to processing.
(1-4) In the Java application output process, content output information is generated from the output information received from the Java application execution unit 12 and the output control information received from the Java application control unit 15 and sent to the display 51. As a result, a display screen is output to the display 51.

  Moreover, the process which controls the propriety of a screen display is performed also at the timing when a vehicle state changed. As shown in the flowchart of FIG. 6, this process is performed when there is a notification that the vehicle state has changed from the monitoring program that periodically monitors the vehicle state to the Java application control unit 15, that is, This occurs when a control call is made. That is, when controlling whether to display the screen depending on whether the vehicle is traveling or stopped, when the vehicle state changes from traveling to stopping or from stopping to traveling, the Java application control unit 15 is controlled. Thus, the above-described controls (1-3) and (1-4) are notified. The monitoring program corresponds to the external state detection means of this invention.

  When the Java screen display is not possible, as shown in FIG. 7A, the mask screen is displayed on the display 51, and the Java screen is not displayed. In this case, as shown in FIG. 7B, the Java screen can be configured to include only a symbol such as an icon and forcibly switch to the navigation screen. Moreover, as shown in FIG.7 (c), it can also comprise so that the angle of the display 51 may be changed so that a driver | operator may not see a screen.

  When the Java screen can be displayed even while the vehicle is running, not only the Java screen is displayed as shown in FIG. 8 (a) but also the navigation screen as shown in FIG. 8 (b). A setting for displaying the screen and the Java screen in half, or displaying the Java screen in the navigation screen, as shown in FIG. 8C, is described in the policy file. It is also possible to configure the screen display according to the setting.

  Further, in the example shown in FIGS. 8B and 8C, the position of the Java screen to be displayed can be designated. In this case, the user can set the positional relationship between the display 51 and the driver's seat in advance, and the position of the Java screen can be determined based on the set positional relationship. Alternatively, the position of the display 51 in the vehicle is detected by a display position measurement sensor 81 that detects the position of the display 51 as described later, and based on the positional relationship between the detected position of the display 51 and the position of the driver's seat. It can also be configured to determine the position of the Java screen. With such a configuration, for example, when the driver is on the right side of the display 51, the Java screen can be displayed on the right side, so that the Java screen can be output at an easily viewable position.

  The Java application control unit 15 can also be configured to limit the display time during traveling by delaying the timing for outputting the output control information by a specified time. For example, a Java application provided by DSRC while traveling can be configured to allow display for only 10 seconds. This specified time can be described in advance in the policy file.

  In the above-described example, the screen display is controlled depending on whether or not the vehicle is running. However, the display to be displayed may be selected. For example, as shown in FIG. 9, the first display (for the driver's seat) cannot display the Java screen while traveling, but the second display (for the rear seat) can display the Java screen even while traveling. Can be configured. This can be realized by adding display information for distinguishing the display to the output control information output from the Java application control unit 15 and performing screen display according to the output control information received for each display in the Java application output processing. .

  Also, as shown in FIG. 10, a display position measurement sensor 81 that detects the position of the display 51 is arranged in the vehicle, and the Java application control unit 15 acquires position information from the display position measurement sensor 81, and the display 51 It can also be configured to send the output control information by determining whether it is on the driver's seat side or the rear seat side. With this configuration, even when the user freely moves the position of the display 51, the control can be switched depending on the position of the display 51. In this case, it is possible to embed a transmitter in the display 51, arrange display position measurement sensors 81 in front of and behind the vehicle, and estimate the position of the display 51 based on the reception sensitivity of each display position measurement sensor 81.

  In addition, as shown in FIG. 11, a policy file update unit 16 may be provided, and the policy file update unit 16 may update the policy file to update the input / output control rules. The policy file update unit 16 corresponds to the content control information update means of the present invention. The policy file update unit 16 can be configured to receive an operation from a user interface such as the remote controller 41, the microphone 42, or the touch panel 43, connect to the Internet, download a new policy file, or be directly edited by the user. When the policy file is updated, the policy file update unit 16 sends a control trigger to the Java application control unit 15 so as to execute control. As a result, the settings updated by the policy file update unit 16 can be immediately reflected.

  Next, user input processing will be described. In the user input process, when receiving an input from the remote controller 41 or the touch panel 43 connected to the operation unit interface 4 or an input obtained by recognizing the voice input from the microphone 42, the Java application control unit 15 Is notified of a control call for notifying execution of control. When input control information is sent from the Java application control unit 15 in response to this control call, the user input process determines whether to notify the Java application execution unit 12 of the input information.

  In addition, state information including the execution state of the Java application is acquired from the Java application execution unit 12, and when it is detected that the execution state of the Java application has changed based on the state information, the control trigger is set to the Java application control unit 15. The Java application execution state management unit (not shown) to be sent to the Java application control unit 15, the Java application control unit 15 responds to the control trigger from the Java application execution state management unit, and the determination result and the vehicle state It can be configured to generate and output input control information and output control information for controlling input / output of the Java application based on the status information received from the acquisition process. According to this configuration, since the operation control can be performed using the change in the content execution state as a trigger, the input / output operation can be controlled only when necessary. As a result, the processing load can be reduced.

  As described above, according to the content input / output control device according to the first embodiment of the present invention, input / output control according to the state of the vehicle can be performed for each Java application, and as a result, for each Java application. It is possible to control whether the operation is possible. Accordingly, for example, a Java application such as a game can be disabled during travel, and the travel support Java app can be enabled during travel. In addition, it is possible to control whether or not the Java application additionally input later can be operated while traveling. Since the content is a Java application, various content providers can easily develop the content.

Embodiment 2. FIG.
The content input / output control apparatus according to Embodiment 2 of the present invention is configured such that the content to be controlled is a Java application, and a plurality of Java applications are operated simultaneously.

The hardware configuration of the car navigation apparatus to which the content input / output control apparatus according to the second embodiment of the present invention is applied is the same as that according to the first embodiment shown in FIG. FIG. 12 is a diagram showing a software configuration of the car navigation apparatus to which the content input / output control apparatus according to Embodiment 2 of the present invention is applied. In this software, a Java application storage unit 17 is added to the software according to the first embodiment, and the Java application execution unit 12 is configured to operate a plurality of Java applications 11 _{1 to} 11 _n in parallel. The Java application storage unit 17 corresponds to the content storage unit of the present invention, and stores the Java application determination result by the Java application determination unit 14 and the Java application itself.

  In the example shown in FIG. 12, the Java application management unit 13, the Java application storage unit 17, the Java application determination unit 14, and the Java application control unit 15 are configured to operate on the car navigation OS. It can also be configured to operate on JavaVM.

  Next, the flow of processing when executing a Java application will be described with reference to the flowchart shown in FIG. Note that the flow of processing when executing the Java application is basically the same as that of the first embodiment shown in the flowchart of FIG. First, Java application input processing is performed. This Java application input process is the same as that of the first embodiment. Next, the Java application determination unit 14 executes a determination process for determining the attribute of the input Java application. This discrimination process is the same as that of the first embodiment. After determining the Java application, the Java application determination unit 14 sends the determination result and the input Java application to the Java application storage unit 17. The Java application storage unit 17 stores the Java application sent from the Java application determination unit 14 and the determination result. As a result, the Java application can be determined in advance, so there is no need to determine at the time of execution.

The Java application storage unit 17 sends the stored Java application to the Java application execution unit 12. The Java application execution unit 12 executes a plurality of Java applications 11 _{1 to} 11 _n in parallel. Also, the Java application execution unit 12 sends a control call for notifying the Java application control unit 15 of the execution of control when the Java application is executed. The Java application control unit 15 controls output information such as screen display and audio output of a plurality of Java applications executed simultaneously by the Java application execution unit 12 based on the determination result received from the Java application storage unit 17, or / Further, input information such as operation input to the Java application by the user is controlled. At this time, the Java application control unit 15 switches control according to the state information acquired by the vehicle state acquisition process, for example, the vehicle speed information.

  Here, the process executed in the Java application control unit 15 will be described in more detail. As in the first embodiment, the Java application control unit 15 interprets the policy file based on the determination result of the Java application sent from the Java application storage unit 17 and determines the operation range for each Java application. In the content input / output control apparatus according to the second embodiment, since there are a plurality of operating apps, it is necessary to know the operating range for each app. Therefore, the Java application control unit 15 includes an operation management table in which an operation range for each Java application obtained as a result of interpreting the policy file is described as shown in FIG.

  As shown in FIG. 14A, the operation management table stores a Java application name and an operation range in association with each other. This association is not limited to the Java application name, and is obtained from the Java application determination unit 14. 14B, in addition to the application provider as shown in FIG. 14B, the Java application storage destination and the Java application acquisition route (Internet, media such as CD and SD card, communication such as DSRC), or It can be performed using a combination thereof. In the operation management table, even if the associated application is “Not Applicable”, it is only necessary to set the corresponding operation range. Similarly, even if “no operation condition” is set in the setting, it is only necessary to set a corresponding permitted operation. In that case, the set operation is always permitted regardless of the operation condition. As in the case of the first embodiment, in addition to describing the control information in the policy file, the control information is stored as a separate file from the policy file or as a Java application including the control information. You can also.

The flow of processing in the case of controlling whether to display the screen depending on whether the vehicle is running or stopped will be described with reference to the flowchart shown in FIG.
(2-1) Display processing for displaying a screen is called from the Java application (X) (X = 1, 2,..., N).
(2-2) The Java application execution unit 12 performs screen display processing for displaying the screen of the Java application (X), and notifies the Java application control unit 15 to execute control, that is, control. Make a call.
(2-3) In response to this control call, the Java application control unit 15 refers to the operation management table and checks the operation range of the Java application (X). Further, the current running state is acquired as the vehicle state, and if the vehicle is running, output control information that disables Java screen display is sent to the Java application output process.
(2-4) In the Java application output process, content output information is generated from the output information received from the Java application execution unit 12 and the output control information received from the Java application control unit 15 and sent to the display 51. As a result, a display screen is output to the display 51.

  Moreover, the process which controls the propriety of a screen display is performed also at the timing when a vehicle state changed. As shown in the flowchart of FIG. 16, this processing is performed when there is a notification that the vehicle state has changed from a monitoring program that periodically monitors the state of the vehicle, that is, when a control call is made. Is called. That is, when controlling whether to display the screen depending on whether the vehicle is traveling or stopped, when the vehicle state changes from traveling to stopping or from stopping to traveling, the Java application control unit 15 is controlled. Thus, the above-described controls (2-3) and (2-4) are notified.

  FIG. 18 is a diagram showing a software configuration of the car navigation apparatus to which the content input / output control apparatus according to Embodiment 3 of the present invention is applied. The car navigation OS is built on various device drivers for operating the car navigation hardware. On this car navigation OS, a navigation service 10, a content 21, a content execution unit 22, a content management unit 23, a content determination unit 24, and a content control unit 25 are provided. The navigation service 10, the content 21, the content execution unit 22, the content management unit 23, the content determination unit 24, and the content control unit 25 are all configured by a program, and a predetermined function is realized by being executed by the CPU 1. The

  The navigation service 10 provides a basic car navigation service such as displaying the current location or setting a destination and performing route guidance. The content 21 is music data recorded on the HDD 8, music data on a medium such as a CD or DVD, or music data sent from a peripheral device 91 such as a mobile phone. The content execution unit 22 corresponds to the content execution means of the present invention and provides an environment for executing content. The content management unit 23 manages the entire content operation. The content discriminating unit 24 corresponds to the content discriminating means of the present invention and discriminates the content attribute. The content control unit 25 corresponds to the content control means of the present invention and performs content input / output control.

  The navigation service 10 includes a content interface module 10b. The content execution unit 22 includes a navigation service interface module 12a. As the content interface module 10b and the navigation service interface module 12a communicate with each other, the navigation service 10 and the content execution unit 22 operate in cooperation.

  Next, the flow of processing during content execution in the content input / output control apparatus according to Embodiment 2 of the present invention will be described with reference to the flowchart shown in FIG. First, content input processing is performed. In this content input process, the music data is transferred to a communication device 61 such as a mobile phone connected to the communication unit interface 6, a DSRC on-board unit, a TV receiver, an AM / FM receiver, a terrestrial digital broadcast receiver, a satellite broadcast receiver, and the like. And sent to the content discriminating unit 24. Note that the music data can be obtained from the HDD 8 or the peripheral device 91.

  Next, the content determination unit 24 executes determination processing for determining the attribute of the acquired content. In this determination processing, as a determination result, a sound source of music data (broadcast such as CD, HDD, and radio, peripheral devices, etc.), title, playback time, music tone, recorder in the case of HDD recording, etc. are sent to the content control unit 25. . As a determination method, the sound source can be easily acquired because it only needs to trace the data transmission source. The music tone is a technique already realized in some commercially available navigation devices, and thus the description thereof is omitted. The recording person can be realized by a method in which the user directly inputs at the time of recording, stores it in association with the music data, and in the case of a peripheral device, notifies the recording person when connected to the car navigation device. In addition, the content determination unit 24 sends the content to the content execution unit 22. The content execution unit 22 sends a control call for notifying the content control unit 25 of execution of control during the content reproduction process.

  The content control unit 25 determines an operation range from the determination result sent from the content determination unit 24 and the operation setting file, and performs control according to the operation range. This operation setting file corresponds to the policy file in the first and second embodiments, and can be configured to be stored in the HDD 8 as a text file. Alternatively, it can be configured to be held as a program. Moreover, as described with reference to the flowchart of FIG. 6 in the first embodiment, the control can be performed even at the timing when the vehicle state changes. The user input process is the same as that in the first embodiment.

  Specifically, the content input / output control apparatus according to the third embodiment can realize the following control. That is, by acquiring the running state as vehicle information, the music playback volume and sound quality are switched between running and stopped. This makes it possible to listen to music comfortably even when the surrounding noise increases due to running from a stop. Volume and sound quality offset parameters are described in advance in the operation setting file. In addition, the operation setting file can be set to accept only user input by voice input from the microphone 42 because the operation by the remote controller 41 is dangerous during traveling.

  Further, by acquiring the travel location as the vehicle status information, it is possible to prohibit the audio output by the music data when the vehicle approaches a specific location. For example, when the current location is before the railroad crossing, audio output by music data is prohibited. According to this configuration, the driver can be alerted. In addition to prohibiting audio output, the volume may be changed to a set volume. In this case, the volume is described in advance in the operation setting file.

  Also, by acquiring passenger information as vehicle status information, when playing music recorded by the driver, the output of the speaker 52 is changed so that the driver's seat becomes the center of the sound, and the person sitting in the passenger seat When playing back the recorded music, the output of the speaker 52 can be changed so that the passenger side becomes the center of sound. The center position of the sound is set in advance by setting parameters such as the driver seat center, passenger seat center, and rear seat center using a mechanism that adjusts the sound position using an attached microphone, which is implemented in some car navigation systems. This can be achieved by describing it in the configuration file. The driver can be identified by inputting an ID or password directly into the car navigation device or by acquiring and identifying personal information stored in a key used by the driver. As a method of identifying the position where the passenger is sitting, a camera is installed in the car, face authentication from the captured image, a connector for installing a mobile phone for each seat, and identification of individuals from information on the mobile phone, etc. This method can be used.

  By acquiring the travel location as the vehicle state information, the volume and sound quality can be prevented from being raised above a certain level while traveling on a highway when the tune has a fast tempo. With this configuration, it is possible to prevent a psychological environment in which the driver can easily speed up.

  As described above, according to the content input / output device according to Embodiment 3 of the present invention, even when the content to be controlled is music data, the input / output control corresponding to the state of the vehicle is performed for each content. As a result, it is possible to control whether or not the operation can be performed for each music.

Embodiment 4 FIG.
The content input / output control apparatus according to the fourth embodiment of the present invention is an example when the content to be controlled is video data (DVD, terrestrial digital broadcast, etc.). The hardware configuration of the car navigation device to which the content input / output control device according to the fourth embodiment of the present invention is applied is the same as that according to the third embodiment shown in FIG. 17 except for the following points. That is, the HDD 8 stores recorded video data, in addition to recorded music data, map data, and programs (navigation programs, etc.).

  The software configuration of the car navigation apparatus to which the content input / output control apparatus according to the fourth embodiment of the present invention is applied is the same as that according to the third embodiment shown in FIG. 18 except for the following points. That is, the content execution unit 22 provides an environment for reproducing video data. Further, the flow of processing during content execution is the same as that of the third embodiment shown in the flowchart of FIG. 19 except for the following points. That is, the input data is video data, and the video and audio are output in the content output process. Hereinafter, the difference from the third embodiment will be mainly described.

  First, content input processing is performed. In this content input process, video data is transmitted to a communication device 61 such as a mobile phone, a DSRC on-board unit, a TV receiver, an AM / FM receiver, a terrestrial digital broadcast receiver, a satellite broadcast receiver, etc. connected to the communication unit interface 6. And sent to the content discriminating unit 24. Note that the video data can also be obtained from the HDD 8 or the peripheral device 91.

  Next, the content determination unit 24 executes determination processing for determining the attribute of the acquired content. In this determination process, the video data source (DVD, HDD, broadcasting such as terrestrial digital broadcasting, peripheral devices, etc.), title, playback time, recorder in the case of HDD recording, etc. are sent to the content control unit 25 as the determination result. It is done. As a determination method, the video source can be easily acquired because it only has to trace the data transmission source. Title, playback time, etc. can be obtained from DVD information in the case of DVD, from program guide data in the case of terrestrial digital broadcasting, and title, playback time, etc. can be saved together with video recording. It can be obtained by placing it. Recorder data can be realized by a method that is directly input by the user at the time of recording, stored in association with the recorded data, and in the case of a peripheral device, the recorder is notified when connected to the car navigation device. In addition, the content determination unit 24 sends the content to the content execution unit 22. The content execution unit 22 sends a control call for notifying the content control unit 25 of execution of control during the content reproduction process.

  The content control unit 25 determines an operation range from the determination result sent from the content determination unit 24 and the operation setting file, and performs control according to the operation range. Since this operation setting file is the same as that of the third embodiment, description thereof is omitted. The user input process is the same as that in the first embodiment.

  Specifically, in the content input / output control apparatus according to the fourth embodiment, the following control can be realized. That is, the volume offset can be changed depending on the video source. For example, the digital terrestrial broadcasting can be left as it is, but when reproducing a DVD, the volume can be increased by a specified value. Further, by acquiring the traveling state as the vehicle state information, the volume can be switched between traveling and stopped.

  Further, by acquiring the traveling state as the vehicle state information, the video data is not output to the display 51 while traveling (the method for not outputting the video data is described in the first embodiment), and the user input is also performed. It can be configured to be unacceptable and to allow only audio output. In addition, when there are a plurality of displays 51, the front seat display may not display an image while traveling, but the rear seat display may display an image even while traveling.

  Also, by acquiring the resource load information as vehicle state information, the content playback processing is reduced if the resource load is high. Specifically, the content playback is stopped or the content playback frame rate is changed. Can be configured. Further, by acquiring the traveling time to the destination as the vehicle state information, it can be configured not to reproduce when the reproduction time of the content is longer than that.

  Moreover, it can comprise so that the brightness of the display 51 may be switched for every video source by acquiring the brightness in a vehicle as vehicle state information. For example, the brightness of the display 51 can be switched for each video source depending on whether it is a sunny day or a cloudy day, or whether it is a general road or in a tunnel. A method of measuring the brightness in the vehicle can be realized by attaching a photosensitive sensor to the display 51. In this case, the current travel location can be acquired as the vehicle state information.

  Further, by acquiring the passenger information as the vehicle state information, it is possible to provide a passenger's favorite reproduction environment. As a passenger identification method, the method described in the third embodiment can be employed. Here, the “favorite” playback environment refers to multilingual audio and subtitle information such as English and Japanese, and video data with multiple viewpoints. This means setting such as These pieces of information set by the user are stored in the operation setting file, and the setting of the operation setting file is automatically validated when the user reproduces video from the next time. With this configuration, even with the same video data, it is possible to enjoy the video in the language sound that the user wants to hear for each seat by changing the display and angle of subtitles in the front seat and the rear seat, or by using a directional speaker.
