Here, the application is a program created in accordance with the work of the user on the computer. For example, each of the applications included in the application group 15A is a small application called a gadget or a widget. There may be. In other words, the application can generate some image information that can be displayed on the display screen, and each of the applications is a concept including a program that can operate on a computer independently or in conjunction with each other.

Further, in the present embodiment, the content is the content of information such as text, voice, and moving image. In this embodiment, each of the plurality of applications included in the application group 15A can generate the content of information such as text, voice, and moving image, that is, the content. In addition, each of the applications can generate image information for displaying the content of the information provided by the content on the display screen as an image. An image generated from the image information to be displayed on the display screen is referred to as a "content image". That is, each of the plurality of applications included in the application group 15A can generate content and generate image information for displaying the information provided by the content as a content image.

In this embodiment, each of the plurality of applications included in the application group 15A acquires the information necessary for generating the content by communicating with the external device.

The storage unit 15 stores a map database 15B in which map information used for generating contents is stored. The content display control device 10 may acquire map information from a navigation device (not shown). Further, various programs used in the content display control device 10 may be acquired from, for example, another server device or the like via the network NW.

The control unit 17 is a computer that includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), and controls the operation of the content display control device 10. The control unit 17 realizes various functions by reading and executing various programs stored in the ROM and the storage unit 15 by the CPU.

The control unit 17 includes an application control unit 17A.

The display control unit 17B controls to selectively display a plurality of content images generated by each of the plurality of applications on the display 11A as a display screen.

For example, the display control unit 17B scrollably displays the content images corresponding to a predetermined number of contents among the plurality of contents, so that the plurality of content images are selectively displayed on the display 11A. Further, for example, the display control unit 17B selectively displays the plurality of content images on the display 11A by displaying the content images corresponding to a predetermined number of contents selected from the list of the plurality of contents. ..

The communication unit 19 is a network adapter such as a NIC (Network Interface Card) connected to a wireless device (not shown). The control unit 17 communicates data with the outside via the communication unit 19. For example, the control unit 17 transmits / receives data to / from the content distribution server 30 via the communication unit 19.

For example, the control unit 17 receives data required for generating content by each of the applications from the content distribution server 30 via the communication unit 19. In addition to communication with the content distribution server 30, the control unit 17 may perform communication such as data collection by VICS (registered trademark) or vehicle-to-vehicle communication via the communication unit 19.

The input unit 21 is connected to the touch pad 11B of the touch panel 11 provided on the vehicle M. The input unit 21 is an interface that detects an input operation to the touch pad 11B and supplies a signal indicating the input operation to the control unit 17. For example, the input unit 21 detects an input operation related to selection or search on the content displayed on the display 11A of the touch panel 11.

FIG. 4 shows an image displayed on the display 11A as a display screen of the touch panel 11. Further, in FIG. 4, the arrow drawn on the outside of the display 11A indicates the vertical direction of the display 11A.

As shown in FIG. 4, the display 11A has a map display area NV and a content display area AR as a display area. As shown in FIG. 4, in the map display area NV, a navigation screen is displayed on which information on the travel of the moving body such as the distance to the destination is superimposed on the map.

Further, as shown in FIG. 4, a plurality of frame FRs arranged continuously in the vertical direction are displayed in the content display area AR on the display 11A. The plurality of frame FRs are displayed so as to be slidably movable in the vertical direction. In each of the frame FRs, a content image corresponding to the content generated by each of the applications included in the application group 15A is displayed. In other words, the area where the content image of 1 is displayed is defined by the frame FR of 1.

In the example of FIG. 4, the case where the two frame FRs are located in the content display area AR is shown. The content image is also generated for the frame FR located outside the content display area AR, that is, outside the display screen.

For example, when the frame FR slides up and down by the user's operation, the frame FR located outside the content display area AR is brought into the content display area AR, and the frame brought into the content display area AR. The content image generated for FR is displayed. In this way, each of the content images generated for each frame FR is scrolled and displayed in the content display area AR.

For example, regarding this scroll display, the display control unit 17B of the control unit 17 receives a touch operation on the touch pad 11B indicating scrolling via the input unit 21 and performs display control according to the touch operation. For example, when a swipe operation or a flick operation is accepted as a touch operation, display control is performed so that the frame FR is moved in the vertical direction.

Therefore, the display control unit 17B receives a touch operation by the user of the content display control device 10 and scrolls the display to selectively display the content image desired by the user among the plurality of content images on the display 11A. It is possible.

For example, in FIG. 4, a content image for playing a moving image is displayed in the frame FR located on the upper side in the content display area AR. Further, for example, in FIG. 4, in the frame FR located on the lower side in the content display area AR, for example, a content image capable of accepting input of a keyword and searching for a moving image is displayed.

Further, FIG. 4 shows word-of-mouth information around the current location as an example of a content image generated for a frame FR located below the content display area AR, which is an area outside the content display area AR. The content image is displayed. Further, in FIG. 4, as an example of the content image generated corresponding to the frame FR located below the content for posting the word-of-mouth information, the content image showing the ranking of popular stores around the current position of the vehicle M is shown. It is displayed.

For example, in FIG. 4, when the display in the content display area AR is scrolled upward by one frame FR, the frame FR located outside the content display area AR is brought into the content display area AR. , The content image of the word-of-mouth information generated for the brought-in frame FR is displayed in the content display area AR.

The content image generated for the frame FR located in the content display area AR is a “display state” which is a state displayed on the display 11A. On the other hand, the content image generated for the frame FR located outside the content display area AR is in a “non-display state” in which it is not displayed on the display 11A. As described above, the content and the content image are generated even in the hidden state.

Further, as described above, each of the plurality of applications that generate each of the plurality of contents communicates with an external device such as the content distribution server 30 in order to generate the contents. As described above, since the content is generated even in the hidden state, the application that generates the content performs communication for generating the content even in the hidden state.

However, there may be cases where there is no problem even if at least a part of the information transmitted / received by the communication is not transmitted / received in the generation of the content in the hidden state. Therefore, in the non-display state, it can be said that communication does not necessarily have to be performed in the same mode as the communication mode in the display state.

In the present embodiment, the application control unit 17A of the control unit 17 is in a hidden state in which each of the plurality of content images is not displayed on the display 11A, or is in a display state displayed on the display 11A. Therefore, the mode of communication with each external device of the plurality of applications can be determined and changed.

For example, in the application control unit 17A, when the content image corresponding to the content generated by one application is in the display state, the application performs normal communication with an external device, whereas the content image is When it is in the hidden state, the application may be controlled so as not to perform communication.

Further, for example, the application control unit 17A may set the mode of communication of the corresponding application to a mode of suppressing the amount of communication when the content image is in the non-display state.

As a mode of communication that suppresses the amount of communication, for example, reducing the transfer speed during communication can be mentioned. For example, the application control unit 17A may reduce the number of items for updating the data used for content generation in order to reduce the transfer speed and perform communication.

Specifically, for example, an application that generates content that displays the ranking of popular stores around the current position is a commercial facility related to the current position when the content image corresponding to the content is displayed. Communication is performed to acquire both the information indicating the location and the information indicating the frequency at which each commercial facility is set as the destination. When the content image is hidden, the application may reduce the number of items for which data is updated by performing communication for acquiring only information indicating the location of the commercial facility.

Further, for example, each of the applications may change the communication method depending on whether the generated content image is in the display state or the non-display state. For example, a high-speed communication method may be used for normal communication in the display state, and a low-speed communication method may be used for communication in the non-display state. For example, each of the applications uses a 4th generation mobile communication system in the display state and a 3rd generation mobile communication system or a wireless communication system having a lower communication speed in the non-display state. May be good. As a result, the transfer speed of communication in the hidden state can be limited, and the cost of communication can be reduced.

Another aspect of suppressing the amount of communication is to reduce the total amount of data to be communicated within a certain period of time. For example, the application control unit 17A may reduce the frequency of updating the data in order to reduce the total amount of data to be communicated within a certain period of time.

By changing the mode of communication in this way, it is possible to avoid performing unnecessary communication and suppress the amount of communication. Further, the processing load of the content distribution server 30 and the content display control device 10 as an in-vehicle device can be reduced, and the power consumption can be reduced.

FIG. 5 shows a content image generated corresponding to six frame FRs arranged continuously in the vertical direction together with the touch panel 11. “Cont. AF” in FIG. 5 shows six content images A to F generated by each of the corresponding applications. In this embodiment, the case where the six frame FRs have the same size and shape will be described. The size in this embodiment indicates the apparent size of the content image.

In FIG. 5, as in the case of FIG. 4, a navigation screen is displayed in the map display area NV on the display 11A, and the content image generated for each of the two frame FRs in the content display area AR. C (Cont. C) and content image D (Cont. D) are displayed.

That is, in FIG. 5, among the content images A to F, the content images C and D are in the display state, and the content images A, B, E and F are in the non-display state. The six frame FRs in which the content images AF are generated are scrolled in the vertical direction while maintaining the vertical arrangement. Therefore, as the frame FR scrolls, the content images AF are also scrolled and displayed in a predetermined order. That is, the content images A to F are selectively displayed (scrolled) in a predetermined scrolling order starting from the content image in the displayed state.

For example, in FIG. 5, when the content images AF are scrolled upward, the content images "ABCDEF" are displayed in this order. On the contrary, when the content images AF are scrolled downward, the content images "FEDCBA" are displayed in this order.

Therefore, when the content images are displayed in a predetermined scrolling order, the order is from the content image in the displayed state to the display of the content image in the non-display state, that is, the order in which the content image is scrolled to the display state. The display order varies depending on which content image is in the display state.

Hereinafter, an example of a display order (hereinafter, also simply referred to as “display order”), which is the order in which the hidden content images are scrolled in units of frame FR and displayed in the content display area AR, will be described.

First, since the content image in the display state has already been displayed, the display order is set to "0". Next, the display order of the content images in the non-display state, which are displayed when the content image in the display state is scrolled by one frame FR in any of the vertical directions as the starting point, is set to "1". In other words, the display order of the content images corresponding to the frame FR located one frame FR outside the content display area AR is “1”.

Further, the display order of the content images in the non-display state and displayed when the content image in the display state is scrolled by two frame FRs in any of the vertical directions as the starting point is set to "2". That is, the display order of the content images corresponding to the frame FRs located two frame FRs outside the content display area AR is “2”.

For example, in FIG. 5, the display order of the content images C and D is "0", the display order of the content images B and E is "1", and the display order of the content images A and F is "2". ..

As described above, each of the applications that generate the content images AF suppresses the amount of communication depending on the mode of communication with the external device depending on whether the corresponding content image is in the display state or the non-display state. It can be changed to the mode of

More specifically, each of the applications determines the mode of communication with the external device for the corresponding content image according to a predetermined scrolling order of the plurality of content images starting from the content image in the display state. can do.

When changing the mode of communication, the degree of suppressing the amount of communication may be changed according to the display order, which is the order until each content image is displayed.

For example, the application control unit 17A may control each of the applications so that when the display order of the content images is slower than the predetermined display order, the degree of suppressing the communication amount becomes larger. For example, the predetermined display order may be determined for each application, or may be determined according to the nature of each application.

Further, for example, the application control unit 17A may control each of the applications so that the slower the display order, the greater the degree of suppressing the communication amount.

For example, in FIG. 5, when the content image C and the content image D are in the display state, the content image A and the content image F whose display order is “2” are the content image B and the content image F whose display order is “1”. It can be said that the order until the content image E is displayed on the display 11A is later than that of the content image E. In this case, the degree of suppressing the communication amount of the content image A and the content image F may be larger than that of the content image B and the content image E.

For example, for the same content image, if the display order is "1", the communication frequency may be reduced, and if the display order is "2", communication may not be performed.

In this way, the slower the display order, the greater the degree to which the amount of communication is suppressed, thereby suppressing unnecessary communication when the content image is in the non-display state and when the content image is in the display state. It is possible to immediately display an appropriate content image.

Regarding the suppression of the communication volume, it is possible to control the timing at which the suppression of the communication volume is started and the level of the communication volume in more detail.

For example, while the scroll operation from the user is being accepted, in each application, a level of communication amount corresponding to the display order of the corresponding content images may be set at predetermined time intervals. The predetermined time may be, for example, about 0.1 seconds. It is possible to optimize the amount of communication that follows the scroll operation, and it is possible to suppress unnecessary communication during the scroll operation. For example, the slower the display order, the lower the level of communication volume.

Further, for example, while the scroll operation from the user is being accepted, the communication amount of each application may be fixed to the communication amount set immediately before the scroll operation reception.

Then, immediately after the scroll operation is completed, a level of communication amount corresponding to the display order of the corresponding content images may be set.

Alternatively, while the scroll operation from the user is being accepted, the communication volume of each application is fixed to the communication volume set immediately before the scroll operation reception, and waits for a certain time when the scroll operation is completed. However, when the scroll operation is not accepted even after the lapse of the certain time (standby time), the communication amount of the level corresponding to the display order of the corresponding content images may be set. The waiting time may be, for example, 5 seconds.

For example, the standby time may be set at the time of shipment of the content display control device 10, or an arbitrary time may be set. Further, for example, the waiting time may be determined based on the history of the time interval from the completion of the scroll operation to the acceptance of the next scroll operation in the content display control device 10.

Further, for example, while the scroll operation from the user is being accepted, the communication amount of each application may be set as the communication amount set in the display state. Then, after the scroll operation is completed, a level of communication amount may be set according to the display order of the corresponding content images. As a result, the content image in the displayed state can be reliably displayed immediately after the scroll operation is completed.

Further, for example, while the scroll operation from the user is being accepted, each application may be put into a non-communication state and the communication amount may be set to zero. After the scroll operation is completed, a level of communication amount may be set according to the display order of the corresponding content images. It is possible to reduce the amount of communication during reception operation.

In addition, in FIGS. 4 and 5, in addition to changing the communication mode of the corresponding application depending on whether each of the plurality of content images is in the display state or the non-display state, each of the contents of the plurality of content images Depending on the nature, the mode of communication in the hidden state may be defined.

For example, for content that displays real-time information or information related to the current position, it is sufficient to communicate only in the displayed state, and the communication of the application may be stopped in the hidden state. ..

For example, regarding the content that displays the real-time ranking and the content that displays the information related to the current position, the communication of the application may be stopped in the hidden state. Further, for example, it is preferable to stop the communication of the application in the hidden state for the content for which the usage fee is incurred.

For example, for content having a property that requires periodic uploading of information on the running of vehicle M to a server, the communication of the application that generates the content is not stopped even in the hidden state. Communication may be performed in a manner in which the amount of communication can be suppressed while continuing the necessary communication.

For example, even for content that requires continuous download of data from the server, the amount of communication is suppressed to the extent that necessary communication can be continued without stopping the communication of the application in the hidden state. You may do it.

For example, as described above, when suppressing the amount of communication for content whose communication is preferably not stopped even in the hidden state, the amount of communication is suppressed to the extent that necessary communication can be continued. May be. That is, with respect to the content, the degree of suppressing the communication of the application in the hidden state may be reduced.

For example, with respect to the content for streaming the moving image, the image download may be stopped and only the audio may be downloaded in the hidden state. Depending on the nature of the content, the mode of communication in the non-display state may be the same as the mode of communication in the display state.

When the content images A to F are displayed in a predetermined scrolling order, for example, if they are scrolled in the direction starting from A and toward F and displayed up to F, even if they are further scrolled in the same direction. The display may not change. Alternatively, A may be displayed again after F, and the display from A to F may be repeated.

FIG. 6 is a sequence diagram showing an outline of the control executed by the application control unit 17A and the display control unit 17B of the control unit 17. The application control unit 17A and the display control unit 17B start the sequence shown in FIG. 6, for example, when the power of the display control device 10 is turned on.

The application control unit 17A reads and executes each of the plurality of applications included in the application group 15A of the storage unit 15 (step S101). The application control unit 17A starts controlling the communication of each application so as to have a predetermined mode (step S102). For example, the predetermined mode may be a mode in which all the communication necessary for generating the content is executed, or a mode in which the amount of communication is suppressed.

When the communication of each application is started, the application control unit 17A causes each application to start generating the content (step S103), and supplies the image data of the generated content to the display control unit 17B (step S104).

When the image data for displaying the content is supplied, the display control unit 17B starts displaying the content image (step S105). For example, in step S105, the display control unit 17B controls to display two of the plurality of content images on the display 11A to display the display state and to hide the other content images.

After that, when the display control unit 17B receives an input operation indicating the start of the scroll operation performed on the touch panel 11 via the input unit 21 (step S106), the display control unit 17B scrolls the content image according to the input operation (step S107). ). For example, in step S107, the content image is scrolled and displayed in the content display area AR on the display 11A according to the direction and movement amount of the touch operation on the touch pad 11B.

When the display control unit 17B receives an input operation indicating the end of the scroll operation (step S108), the application control unit 17B sends a display state notification indicating whether the content image corresponding to each content is in the display state or the non-display state. This is performed for 17A (step S109). For example, in step 109, when the end of the scroll operation is accepted in step S108, it is notified whether it is in the display state or the non-display state.

Upon receiving the display state notification, the application control unit 17A changes the communication mode of each of the plurality of applications in a manner depending on whether the content image corresponding to each content is in the display state or the non-display state. (Step S110).

The display control routine RT1 which is an example of the routine executed by the display control unit 17B and the communication control routine RT2 which is an example of the routine executed by the application control unit 17A will be described with reference to FIG. 7. As an example, a case where the application A, which is an application for generating the content image A, is controlled will be described.

The display control unit 17B starts the display control routine RT1 when, for example, the application A is started and the content image A is generated. When the display control unit 17B starts the display control routine RT1, the display control unit 17B waits for a scroll operation for the display area RA on the display 11A (step S201). In step S201, the display control unit 17B waits for a scroll operation, which is an input operation indicating scrolling to the touch pad 11B in the display area RA.

The display control unit 17B determines whether or not the scroll operation has been started after the execution of step S201 (step S202). In step S202, the display control unit 17B determines whether or not the scroll operation to the touch pad 11B in the display area RA has been accepted via the input unit.

If the display control unit 17B determines in step S202 that the scroll operation has not been started, the display control unit 17B returns to step S201 and waits for the scroll operation again. In step S202, when it is determined that the scroll operation has been started, the display control unit 17B performs a scroll display in which each of the content images is scrolled and displayed (step S203). For example, in step S203, the display control unit 17B controls the display of the content image to move in either the up or down direction according to the scroll operation.

After executing step S203, the display control unit 17B determines whether or not the scroll operation has been completed (step S204). In step S204, the display control unit 17B determines whether or not the input operation received via the input unit has been completed. When the display control unit 17B determines in step S204 that the scroll operation has not been completed, the display control unit 17B returns to step S203 and continues the scroll display.

When the display control unit 17B determines in step S204 that the scroll operation has been completed (step S204: YES), the display control unit 17B notifies the display state indicating whether each content image is in the display state or the non-display state (step S204: YES). Step S205). In step S205, the display control unit 17B supplies the display status notification to the application control unit 17A.

After executing step S205, the display control unit 17B ends the display control routine RT1 and repeatedly executes the display control routine RT1.

When the application control unit 17A starts the communication control routine RT2, the application control unit 17A waits for the display status notification from the display control unit 17B (step S301). After executing step S301, the application control unit 17A determines whether or not the display status notification has been received (step S302).

In step S302, when the application control unit 17A determines that the display status notification has not been received (step S302: NO), the application control unit 17A returns to step S301 and waits for the display status notification again. In step S302, the application control unit 17A determines that the display status notification has been received (step S302: YES), and determines whether or not the content image A is in the display state based on the display status notification (step S302: YES). S303).

In step S303, when the application control unit 17A determines that the content image A is in the display state (step S303: YES), the application control unit 17A communicates in the normal mode, which is the communication mode when the content image A is displayed. In addition, application A is controlled (step S304).

In step S303, when the application control unit 17A determines that the content image A is not in the display state (step S303: NO), the application control unit 17A controls the application A so as to perform communication in a mode in which the amount of communication is suppressed as compared with the normal mode. (Step S305). For example, the communication control of the application A in step S305 may be performed in a manner corresponding to the nature of the content image A.

After executing step S304 or step S305, the application control unit 17A ends the communication control routine RT2 and repeatedly executes the communication control routine RT2.

FIG. 8 is a flowchart showing a communication control routine RT3 which is a modification of the communication control routine RT2. In FIG. 8, substantially the same steps as in the case of the communication control routine RT2 are designated by the same reference numerals.

When the application control unit 17A starts the communication control routine RT3, it waits for the display status notification from the display control unit 17B (step S301), and when it receives the display status notification (step S302), the content image A is in the display state. Whether or not it is determined (step S303).

In step S303, when the application control unit 17A determines that the content image A is not in the display state (step S303: NO), whether or not the display order, which is the order until the content image A is in the display state, is 2 or more. (Step S401).

In step S401, the application control unit 17A determines, for example, whether or not the display order, which is the order until the display state is reached, is two or more frame FRs, as shown in FIG.

For example, the display order information, which is information indicating the display order of the content image A, may be included in the display status notification. In this case, in step S401, the application control unit 17A may determine whether or not the display order is 2 or more based on the display order information.

An example is shown in which the display order used as the determination criterion in step S401 is 2, but the present invention is not limited to this. For example, different determination criteria may be set according to the nature of the content of the content image. That is, in step S401, it is determined whether or not the display order of the content image A is later than the predetermined display order based on the predetermined display order.

When the application control unit 17A determines in step S401 that the display order is not 2 or more (step S401: NO), the application control unit 17A controls the application A to communicate in the first suppression mode (step S402).

In step S402, for example, the application control unit 17A controls the communication so that the degree of suppression of the communication amount is small and the communication can be changed to the communication in the normal mode as soon as the display state is reached.

When the application control unit 17A determines in step S401 that the display order is 2 or more (step S401: YES), the application control unit 17A controls the application A to communicate in the second suppression mode (step S403).

In step S403, the application control unit 17A controls communication in a mode in which the degree of suppression of the communication amount is larger than that of the first suppression mode, for example. In step S403, for example, communication of application A may be stopped.

For example, the application A may collect only the data necessary for calculating the ranking in step S402, and stop the communication in step S403.

After executing step S304, step S402, or step S403, the application control unit 17A ends the communication control routine RT3 and repeatedly executes the communication control routine RT3.

As described above, according to the content display system 100 including the content display control device 10 of the present embodiment, a part of the plurality of content images corresponding to each of the plurality of applications included in the application group 15A is displayed on the vehicle.
