The audio data of the content thus output is output to the speaker 17.

  The device information receiving unit 31 receives device information from the mobile terminal device 50. Specifically, the device information receiving unit 31 performs both encoding and decoding of data using the screen size of the mobile terminal device 50, the transmission speed of the module built in the mobile terminal device 50, and the encoding method. The mobile terminal device 50 can receive the codec, the remaining battery level of the mobile terminal device 50, and the like from the mobile terminal device 50 that has been paired via the wireless communication unit 23. Then, the device information reception unit 31 outputs each received information to the transmission unit 33.

  The request receiving unit 32 receives various content transmission requests from the mobile terminal device 50. Specifically, the request receiving unit 32 receives an acquisition request for content displayed or output at a local point on the display 18 from the mobile terminal device 50 that has been paired, and The request is output to the transmission unit 33. For example, the request receiving unit 32 receives a transmission request having a request content name or a request content ID input by the mobile terminal device 50 as a header.

  When the transmission request is received by the request reception unit 32, the transmission unit 33 converts the content format based on the device information received by the device information reception unit 31 and transmits the content to the mobile terminal device 50. Specifically, when the transmission request is received by the request reception unit 32, the transmission unit 33 determines whether or not the content corresponding to the transmission request is the content displayed on the display 18. Judged from the header of the transmission request. When the content corresponding to the transmission request is stored in the internal memory 30a of the control unit 30 or the content displayed on the display 18, the transmission unit 33 stores the content from the internal memory 30a.

To the mobile terminal device 50. Further, for example, when the “module transmission rate” is received as the device information by the device information receiving unit 31, the transmission unit 33 can transmit the content corresponding to the transmission request at the bit rate within the “module transmission rate” received. It compresses so that it may transmit to the portable terminal device 50.

  In addition, when “owned codec” is received as device information by the device information receiving unit 31, the transmitting unit 33 is capable of decoding with the “owned codec” that has received the content corresponding to the transmission request (for example, H .264, MPEG, etc.) and transmitted to the portable terminal device 50. In addition, when the “battery remaining amount” is received as the device information by the device information receiving unit 31, the transmission unit 33 does not reduce the “battery remaining amount” that has received the content corresponding to the transmission request unnecessarily. The image is thinned out and transmitted to the mobile terminal device 50.

  Further, the transmission unit 33 may receive a plurality of the above device information. For example, when the device information receiving unit 31 receives “screen size” and “owned codec” as the device information, the transmitting unit 33 encodes the content corresponding to the transmission request that can be decoded by the “owned codec”. When encoding by the technique, the mobile terminal device 50 is compressed and encoded so that the mobile terminal device 50 can be displayed in a size suitable for the “screen size”, and transmitted to the mobile terminal device 50.

[Processing by in-vehicle device]
Next, processing by the in-vehicle device will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart illustrating a flow of device information reception processing in the in-vehicle device according to the first embodiment, and FIG. 4 is a flowchart illustrating a flow of content conversion transmission processing in the in-vehicle device according to the first embodiment.

(Device information reception process flow)
As illustrated in FIG. 3, when the in-vehicle device 10 receives a connection request (pairing request) from the mobile terminal device 50 (Yes in step S101), the in-vehicle device 10 executes a pairing process with the mobile terminal device 50, A terminal that is wirelessly connected to the in-vehicle device 10 is identified, and authentication / encryption is set with the identified terminal (step S102).

  The in-vehicle device 10 that has identified the terminal to be connected in this way receives, for example, at least one of the screen size, the module transmission speed, the possessed codec, and the remaining battery level as device information from the mobile terminal device 50 that has executed the pairing process.

(Content conversion transmission process flow)
As illustrated in FIG. 4, when the in-vehicle device 10 that has performed the processing illustrated in FIG. 3 receives a transmission request from the mobile terminal device 50 (Yes in step S201), the content corresponding to the transmission request is currently displayed on the display 18. It is determined whether or not the content is being processed (step S202).

  When the content corresponding to the transmission request is the content currently displayed on the display 18 (Yes at Step S202), the in-vehicle device 10 converts the content format based on the device information received in FIG. (Step S203), the converted content is transmitted to the portable terminal device 50 (Step S204).

  On the other hand, if the content corresponding to the transmission request is not the content currently displayed on the display 18 (No at Step S202), the in-vehicle device 10 is the content stored in the internal memory 30a such as the control unit 30. Is determined (step S205).

  When the content is stored in the internal memory 30a (Yes at Step S205), the in-vehicle device 10 acquires the corresponding content from the internal memory 30a (Step S206), and converts the content format based on the device information. Then, the converted content is transmitted to the mobile terminal device 50 (step S204).

  On the other hand, when the content is not stored in the internal memory 30a (No at Step S205), the in-vehicle device 10 acquires the corresponding content from the center 60 (Step S207), and converts the content format based on the device information ( In step S203, the converted content is transmitted to the portable terminal device 50 (step S204).

[Effects of Example 1]
Thus, according to the first embodiment, the in-vehicle device 10 receives device information from the mobile terminal device 50, receives transmission requests for various contents from the mobile terminal device 50, and receives a transmission request. Based on the received device information, various content formats can be converted and transmitted to the mobile terminal device 50. As a result, both the front seat passenger and the rear seat passenger in the vehicle can view the content displayed on the display 18 without a sense of incongruity, and the information can be reliably shared in the vehicle.

  Further, according to the first embodiment, when the content corresponding to the transmission request is stored in the storage unit such as the internal memory 30a, the in-vehicle device 10 acquires the content from the storage unit and acquires the acquired content. When the content corresponding to the transmission request is not stored in the storage unit, the content is acquired from the center 60, and the acquired content is converted into a format suitable for the device information and transmitted to the mobile terminal device 50. Can be converted based on the device information and transmitted to the mobile terminal device 50. As a result, different contents can be displayed on the in-vehicle device 10 and the mobile terminal device 50.

  In addition, content that is not currently displayed on the display 18 such as content that has been displayed in the past can be transmitted to the mobile terminal device 50 in the vehicle, and the user's detailed needs can be met. In addition, since the content is reproduced using the display and the speaker of the mobile terminal device 50, the content can be sufficiently enjoyed even in the rear seat such as a minivan.

  Further, according to the first embodiment, the in-vehicle device 10 receives at least one of the screen size, the module transmission speed, the possessed codec, and the remaining battery level as device information from the mobile terminal device 50. As a result, a special function is not required for the mobile terminal device 50, and a normal mobile phone or notebook computer can be used. Therefore, convenience for the user is improved.

  By the way, in Example 1, although the vehicle-mounted apparatus 10 demonstrated the example which transmits the content corresponding to the transmission request transmitted from the portable terminal device, this invention is not limited to this, For example, a vehicle-mounted apparatus 10 or an operation screen of another vehicle-mounted device connected to the vehicle-mounted device 10 can be transmitted.

  Accordingly, in the second embodiment, an example in which an operation screen acquisition request is received from the mobile terminal device 50 and a corresponding operation screen is transmitted will be described with reference to FIG. FIG. 5 is a flowchart illustrating the flow of the operation screen transmission process in the in-vehicle device 10 according to the second embodiment.

  As illustrated in FIG. 5, when the in-vehicle device 10 receives a transmission request from the mobile terminal device 50 that has performed the pairing process (Yes in step S301), the in-vehicle device 10 determines whether or not the transmission request is an operation screen request ( Step S302).

  When the received transmission request is an operation screen request (Yes at Step S302), the in-vehicle device 10 acquires an operation screen that is generated or stored in the internal memory 30a or the like, and device information of the mobile terminal device 50 Is converted based on, and transmitted to the portable terminal device 50 (steps S303 and S304).

  For example, as shown in FIG. 6, the in-vehicle device 10 has a DVD operation screen having “play, stop, rewind, fast forward, take-out, navigation operation screen for shifting to another device”, etc. As described above, various operation screens such as an in-vehicle device operation screen for selecting which device in the vehicle to operate such as “air conditioner, volume, navigation screen, fuel consumption information, consumable information, ETC” are generated or acquired from the internal memory 30a. Then send. 6 is a diagram illustrating an example of a DVD operation screen, and FIG. 7 is a diagram illustrating an example of an in-vehicle device operation screen.

  In addition, for example, when the in-vehicle device 10 converts to a format suitable for the “screen size” of the mobile terminal device and transmits it, the coordinates of the operation screen displayed on the display 18 and the operation screen transmitted to the mobile terminal device are displayed. As a result, the position where the operation screen is operated on the mobile terminal device 50 side can be specified.

  Returning to FIG. 5, when the operation screen is selected by the mobile terminal device 50 (Yes in step S <b> 305), the in-vehicle device 10 specifies the operation content from the selected position (coordinates) and the like, and implements the specified operation content. (Step S306).

  For example, when “rewinding” of the “DVD operation screen” is operated by the mobile terminal device 50, the in-vehicle device 10 performs rewinding of the DVD by the disc playback unit 11. Further, when the “air conditioner” of the “vehicle device operation screen” is operated by the mobile terminal device 50, the in-vehicle device 10 further generates or acquires a screen for operating the “air conditioner” and transmits the screen to the mobile terminal device 50. You can also.

  On the other hand, when the received transmission request is not an operation screen request (No at Step S302), the in-vehicle device 10 performs the content conversion transmission process described with reference to FIG. 4 (Step S307).

  Thus, according to the second embodiment, the in-vehicle device 10 operates based on the device information of the portable terminal device 50 when an operation screen acquisition request for operating the in-vehicle device 10 or another in-vehicle device is received. The screen is converted and transmitted to the mobile terminal device 50, and various processes can be executed based on the operation content selected by the user of the mobile terminal device 50 on the transmitted operation screen. As a result, even when content is viewed in the vehicle, other devices such as an air conditioner can be operated without interrupting content viewing.

  Incidentally, in the first embodiment, an example in which both the content image data and the audio data are transmitted to the mobile terminal device 50 has been described. However, the present invention is not limited to this, and only the content image data is carried. The audio data transmitted to the terminal device 50 can be output from the speaker 17 of the in-vehicle device 10. By doing so, the data volume transferred to the mobile terminal device 50 can be greatly reduced, and even when streaming delivery is performed, the mobile terminal device 50 can display streaming video without delay and incongruity. it can.

  In this case, the in-vehicle device 10 performs output adjustment, so-called calibration, between the portable terminal device 50 that is the transmission destination of the image data of the content and the speaker 17 that is the transmission destination of the audio data of the content, By optimizing the phase characteristics of the vehicle interior space, the image data displayed on the mobile terminal device 50 and the audio data output from the speaker 17 of the in-vehicle device 10 can be synchronized. As a result, the owner of the mobile terminal device can view without discomfort like the content displayed on the display 18 of the in-vehicle device 10.

  As a method of synchronization, for example, the in-vehicle device 10 transmits image data to the mobile terminal device 50 when the microphone of the mobile terminal device 50 picks up a sound, and transmits audio data to the speaker 17. May be synchronized with the output.

  The in-vehicle device 10 disclosed in the present application transmits the image data of the content converted into a suitable format to the mobile terminal device 50, and the mobile terminal device among the speakers 17 connected to the in-vehicle device 10. It is also possible to output only to the speaker closest to 50.

  Specifically, the in-vehicle device 10 causes the owner of the mobile terminal device 50 to select which seat to use when performing the pairing process with the mobile terminal device 50. As a result, as shown in FIG. 8, the in-vehicle device 10 identifies the portable terminal device by “a“ seat ”indicating a seat in the vehicle” and a link ID added by performing a pairing process with the portable terminal device. “Rear seat (second row left), link ID = 2, speaker 2” and the like are stored as “portable terminal device” and “speaker” indicating the nearest speaker of the seat. FIG. 8 is a diagram illustrating a correspondence example between a seat, a mobile terminal device, and a speaker.

  By doing in this way, the in-vehicle device 10 specifies the mobile terminal device from the “link ID” included in the received content transmission request header and transmits the image data of the content to the mobile terminal device. The nearest speaker of the mobile terminal device can be specified from the above-described DB, and the audio data of the content can be transmitted to the specified speaker.

  For example, if the “link ID” included in the header of the transmission request for the received content is “2”, the in-vehicle device 10 identifies the mobile terminal device and transmits only the content image data to the mobile terminal device. At the same time, “speaker 3” can be specified as the nearest speaker of the portable terminal device, and the audio data of the content can be transmitted only to the specified speaker 3.

  As described above, in the third embodiment, as shown in FIG. 9, when image data is transmitted to the passenger terminal portable terminal device, the voice data is transmitted to the speaker 2, and the rear seat right portable terminal is transmitted. When image data is transmitted to the device, audio data is transmitted to the speaker 3, and when image data is transmitted to the portable terminal device of the left rear seat, the image data is transmitted to the speaker 4. FIG. 9 is a vehicle schematic diagram showing an example of correspondence between seats and speakers.

  In this way, different passengers can view different contents at the same time in the vehicle.
