  Further, based on the current position from the content data acquisition means for acquiring the content data, the content data playback means for reproducing the content data, the current position acquisition means for acquiring the current position, and the current position acquisition means, Content reproduction control means for selecting content data associated with position information in the vicinity of the position as a reproduction target.

  According to the present invention, the navigation device uses the location information associated with the content data to provide a content playback device that can provide various services such as route setting, information provision around the vehicle location, and advertisements. There is an effect that it can be obtained.

  Hereinafter, a navigation device according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic configuration diagram showing a schematic configuration of an in-vehicle device 10 which is an embodiment of the present invention. As shown in the figure, an in-vehicle device 10 mounted on a vehicle is connected to a touch panel 1, a display 2 and a speaker 3. The in-vehicle device 10 includes a content reproduction unit 11, a navigation unit 12, an input / output control unit 13, a data storage unit 14, a position information utilization unit 15, and a position information-added audio data acquisition unit 16.

  The content reproduction unit 11 is a unit that reproduces content data acquired by receiving a television broadcast or a radio broadcast or reading from a recording medium such as a CD, DVD, MD, or HDD.

  The navigation unit 12 is a unit for setting and guiding a travel route using the position of the host vehicle identified by communicating with a GPS (Global Positioning System) artificial satellite and map data 30 stored in advance.

  The input / output control unit 13 controls the operation of the content reproduction unit 11 and the navigation unit 12 based on the input from the touch panel 1, and mediates the output from the content reproduction unit 11 and the navigation unit 12 to display the display on the display 2. And a processing unit for controlling audio output from the speaker 3.

  The data storage unit 14 is realized by, for example, an HDD (hard disk drive) or the like, and stores content data reproduced by the content reproduction unit 11, map data used by the navigation unit 12, and the like.

  In this way, the in-vehicle device 10 operates as a multifunction machine having a content reproduction function and a navigation function. The main feature of the in-vehicle device 10 according to the present invention is that it acquires content data associated with position information and performs control using the position information associated with the content data when reproducing the content data. is there.

  An example of the data structure of the content data is shown in FIG. In the figure, the content data D10 includes main data D11 and sub data D12. The main data D11 is, for example, music data or audio data compressed in the MP3 format, or moving image data, and the sub data D12 is data associated with the main data.

  As this sub-data D12, information related to the main data D11 such as a music title, artist name, and jacket photo image has been conventionally provided.

  However, since the sub-data D12 is originally defined as an area that can be freely written even if the content is irrelevant to the main data D11, the sub-data D12 can be used for position information such as arbitrary latitude and longitude, and various desired information such as position information. Relevant information can be described.

  The voice data acquisition unit 16 with position information shown in FIG. 1 acquires voice data associated with the position information. The audio data with position information can be acquired by an arbitrary route such as reception by broadcasting or communication, reading from a portable terminal or a portable recording medium.

  For example, digital broadcasting of television and radio, analog FM multiplex broadcasting, cellular phone network, wireless connection with the Internet, communication such as DSRC, etc. can be used for receiving audio data with position information. Further, the audio data with position information may be acquired by connecting to a portable terminal via a USB connection, or may be read from a portable recording medium such as a CD or a DVD.

  The position information using unit 15 directly acquires the sound data with position information from the sound data with position information acquisition unit 16 or reads out the sound data with position information once stored in the data storage unit 14 and uses the position information. Take control.

  Specifically, the location information utilization unit 15 includes therein a route setting request unit 15a, a content selection unit 15b, and a sub information providing unit 15c.

  The route setting request unit 15a performs a process of requesting the navigation unit 12 to set the route with the location information associated with the content data (audio data) as the destination or waypoint.

  On the other hand, the content selection unit 15b acquires position information from the navigation unit 12, and performs processing for selecting content data associated with position information near the current position of the host vehicle as a reproduction target.

  Further, the sub information providing unit 15c performs processing for providing information associated with the content data (audio data) to the user by display output or audio output. For example, a position corresponding to the map displayed on the display unit is displayed in an identifiable manner with an icon or the like, or an address or the like corresponding to the position information is output by voice or the like.

  Next, a specific example of correspondence between main data and sub data will be described with reference to FIG. In the content data D20 shown in the figure, a plurality of sub data D22a to D22e are associated with one audio data D21.

  Here, each of the sub data D22a to D22e is associated with a predetermined reproduction position of the audio data D21. Therefore, when the main data D21 is reproduced by the content reproduction unit, the corresponding sub-data (position information and position related information) changes as reproduction proceeds.

  In the content data D30, a plurality of pieces of sub data D32a to D32e are associated with a plurality of pieces of audio data D31a to D31e. Here, each sub-data D32a-D32e is matched with the some audio | voice data D31a-D31e, respectively.

  When the guidance of various facilities in the city is adopted as the contents of the audio data of the content data D20 and the content data D30, the route setting request unit 15a is located at the sub data D22a to D22d (or the sub data D32a to D32d). In order, the navigation unit 12 sets a route with D22e (or D32e) as the destination.

  Then, in the content data D20, the sub information providing unit 15c provides the user with position related information (for example, guidance on the facility existing at the position) corresponding to the reproduction position of the main data D21.

  In the content data D30, the reproduction of the audio data is started according to the traveling position of the host vehicle, and corresponding position related information, that is, position related information in the vicinity of the current position of the host vehicle is provided to the user.

  When the position information associated with the content data is singular, the route setting request unit 15a requests route setting using the position information as the destination.

  The processing operation of the route setting request unit 15a is shown in the flowchart of FIG. As shown in the figure, the route setting unit request unit 15a receives selection of voice data (step S101), and reads position information associated with the voice data (step S102).

  Then, it is determined whether or not the read position information is singular (step S103). If the position information is singular (step S103, Yes), the navigation unit 12 is configured to set a route with the read position information as the destination. Request (step S104), the process is terminated.

  On the other hand, when there are a plurality of pieces of read position information (No in step S103), the route setting request unit 15a requests the navigation unit 12 to set a route to the target position via the read positions sequentially ( Step S105), the process is terminated.

  The navigation unit 12 receives a route setting request from the route setting request unit 15a, and performs processing such as destination setting and route search.

  When setting the destination, the position may be displayed on a map so that the user can confirm the set point. By doing so, since it is possible to select whether or not to perform the setting at the user's intention, unnecessary guidance and guidance to an incorrect point can be prevented. In particular, when going through a plurality of points, the user can select the order of passage, so that the degree of freedom of setting can be increased, such as being able to move in a desired order of passage.

  FIG. 4-2 shows the processing operation of the navigation unit 12. As shown in the figure, the navigation unit 12 first receives a route setting request from the route setting request unit 15b (step S111), and determines whether there is one destination (step S112).

  As a result, if there is only one destination (step S112, Yes), a map including a point corresponding to the position information is displayed (step S113). And when operation which designates the point as a destination from a user is received (Step S114, Yes), after searching and setting up the course which made the point corresponding to position information the destination (Step S115), The process ends. If there is no instruction from the user to designate that point as the destination (No in step S114), the process is terminated as it is.

  On the other hand, when the destination is not one but passes through a plurality of points (step S112, No), the navigation unit 12 displays a map including the points corresponding to the plurality of pieces of position information (step S116), from the user. If there is no instruction for designating a point as a destination (No in step S117), the process is terminated as it is.

  Also, if there is an instruction from the user to designate that point as the destination (step S117, Yes), an operation of selecting a waypoint (designating the order of passage) is accepted (step S118), and the order of passage from the user Is specified (step S119), the route in the specified via order is searched and set (step S119), and the process is terminated.

  Further, if there is no designation of the order of passage from the user (step S118), a route to reach the target position via each point is set in a prescribed order (for example, the order corresponding to the playback position of the audio data) ( Step S120), the process is terminated.

  Next, the processing operation of the content selection unit 15b will be described with reference to the flowchart of FIG. As shown in the figure, the content selection unit 15b first acquires the current position of the host vehicle from the navigation unit 12 (step S201). Then, voice data having position information close to the current position is searched (step S202), and the voice data obtained as a result of the search is reproduced (step S203).

  Here, as described above, if content data including a plurality of audio data is selected and a route is set so as to travel in the order of the audio data, the content selection unit 15b selects the selected content. The audio data to be reproduced is searched from the audio data included in the data.

  On the other hand, in a state where content data to be reproduced is not designated, the content selection unit 15b searches and reproduces audio data having position information near the current position from all the audio data with position information. In this case, it is not scheduled to be reproduced in advance, but audio data is accidentally reproduced when the host vehicle passes nearby.

  In the processing flow shown in FIG. 5, the reproduction of the sound data obtained by searching from the current position is automatically started. For example, as shown in FIG. The audio data may be displayed on a map based on the position information, and the audio data selected by the user using a touch panel or the like may be reproduced.

  By the way, when position information is associated with the reproduction position of the audio data, a plurality of pieces of position information can be associated with a specific reproduction position. The use of such position information will be described by taking as an example the case where advertisement information is added as sub-information to audio data.

  In the content data D40 shown in FIG. 7, advertisement information D43 is associated with the audio data D41, which is main data, as sub-information. The advertisement information D42 includes a plurality of pieces of position information D42b, D42c, and D42d.

  The advertisement information D42 is, for example, an advertisement of a company that is developing a chain. D42b, D42c, and D42d are location information of each store and location-related information indicating information unique to the store (such as a telephone number and business hours). Have.

  Here, when the content data D40 is reproduced, the sub information providing unit 15c presents the sub information corresponding to the reproduction position, and presents the advertisement information D43 at the reproduction position t1. A specific example of the presentation is shown in FIG. 8, in which the title, artist, and album of the music are displayed on the display GD as the music related information display G1 related to the contents of the content being reproduced.

  Then, a predetermined image G21, a QR code G23 for accessing with a portable terminal, and a text message G24 are displayed as the advertisement information display G2. The image image G21 is, for example, a store symbol mark or a product image, and the text message G24 is a content appealing to a user for a special sale item or a campaign.

  Then, when the user touches the advertisement information display G2, the sub information providing unit 15c switches the display display GD to the map display, and the plurality of pieces of position information D42b, D42c, and D42d included in the advertisement information D42 are as shown in FIG. Display on the map to encourage users to visit. Here, when the user further touches the position information display, the route setting request unit 15 may request to change the route setting so as to guide the user to the store.

  A processing operation in the case of providing advertisement information is shown in the flowchart of FIG. As shown in the figure, first, reproduction of the selected audio data is started (step S301), advertisement information is displayed (step S302), and the advertisement information is displayed on the display (step S303).

  When the touch panel receives an input for selecting advertisement information from the user (step S304, Yes), the position information corresponding to the selected advertisement is displayed on the map (step S305), and the process ends.

  As described above, in the in-vehicle device 10 according to the present embodiment, the audio data with position information acquisition unit 16 reads the audio data associated with the position information from the broadcast, communication, portable terminal, or portable recording medium.
