2 is a flowchart of a method for providing an AVN service according to an embodiment of the present invention. The method described in FIG. 2 may be performed by the AVN system 1 described above in FIG. 1 , and a detailed description of each step included in the method is referred to as the description in FIG. 1 .

Referring to FIG. 2 , the AVN system 1 stores, in the memory 10 , execution state information of an application related to the AVN at the point in time when a signal to cut off the power of the vehicle (ie, a blocking signal) is received. do (S110).

When the execution state information is stored in the memory 10, the power of the vehicle is cut off (S120). The power cut off of the vehicle is controlled by the driving unit (not shown) of the vehicle, and when the execution state information is safely stored by the AVN system 1 , the driving unit completely cuts off the power of the vehicle.

Thereafter, when power is supplied to the vehicle again, the AVN system 1 executes the AVN-related application in the execution state at the time the blocking signal is received based on the execution state information stored in the memory 10 ( S130 ).

For example, when the AVN-related application is an audio application for playing music, the AVN system 1 checks the content information (preferably, song information) that was being played before the power was cut off based on the running state information. and the music corresponding to the confirmed song information can be continuously played from a predetermined playback resumption point. Here, the predetermined playback resume point is determined based on information on the playback resume point included in the execution state information.

As another example, when the AVN-related application is a video application for playing an image, the AVN system 1 checks the content information (preferably, video information) that was being played before the power was cut off based on the running state information. Then, an image corresponding to the confirmed video information can be continuously reproduced from a predetermined playback restart point. Here, the predetermined playback resume point is determined based on information on the playback resume point included in the execution state information.

In some cases, when the application associated with the AVN is a streaming application, the AVN system 1 executes the streaming application again to provide a seamless streaming service. Send a streaming URL request with at least some of it. Here, the streaming platform may be composed of one or more computing devices, but is not limited thereto. In a preferred embodiment, at least a part of the execution state information transmitted to the streaming platform includes at least one of content information and information on a playback restart point.

On the other hand, each step of the method of providing a seamless AVN service provided by the vehicle having the above-described AVN system 1 will be schematically described as being supported by the AVN system 1 or one or more processors provided in the vehicle. may be

According to the present invention, even when the power of the vehicle is cut off, before the power supply to the AVN system 1 is stopped, the AVN system 1 stores the execution state information of the AVN-related application in the memory 10 by , there is an advantage that the AVN system 1 can seamlessly reproduce content that was played before the power was cut off using pre-stored execution state information when power is supplied to the vehicle again.

3 is a schematic flowchart for outputting last audio as an embodiment of the present invention.

Referring to FIG. 3 , the AVN system 1 receives, as a user input, a signal to cut off power to the vehicle ( S210 ).

When a signal to cut off the power to the vehicle is received, the AVN system 1 stores state information of the infotainment application associated with the AVN at the time the signal is received in at least a part of the memory area of the application framework (S220) .

The state information refers to execution state information. The running state information includes information about a state in which a corresponding (infotainment) application was running before or just before the power was cut off, that is, the last mode. When audio is being output immediately before the infotainment application is terminated, the application framework may store, for example, last play information about the audio. The last playback information includes information about a song being played and time information about the last playback time.

The AVN system 1 receives, as a user input, a signal for supplying power to the vehicle ( S230 ).

When power is supplied to the AVN system 1 again, the AVN system 1 requests the last audio using the service agent (S240), and controls the application framework so that the last audio is played continuously from the last playback point according to the request. It can be done (S250).

Last audio refers to audio corresponding to last reproduction information. The service agent checks the last play information stored in the memory area of a predetermined application framework, and supports the AVN system 1 so that audio corresponding to the last play information is played externally. As a result, the AVN system 1 can seamlessly and continuously reproduce the last audio that was being played before the power was cut off.

In an embodiment of the present invention, in response to the infotainment application being executed before S210 , a host message informing that the infotainment service is ready may be transmitted from the application framework to the AVN system 1 by the service agent.

In another embodiment of the present invention, the embodiment related to audio may be equally applied to video.

On the other hand, the last mode of the infotainment application may include a display screen irrelevant to audio or video playback, so that the AVN system 1 can seamlessly service not only audio or video, but also the screen being displayed. In this case, the display screen output by the AVN system 1 will be described with reference to the flowchart of FIG. 5A .

4 is a schematic flowchart for outputting a last screen as another embodiment of the present invention.

Referring to FIG. 4 , the AVN system 1 receives, as a user input, a signal to cut off power to the vehicle ( S310 ).

When a signal to cut off the power to the vehicle is received, the AVN system 1 stores state information of the infotainment application associated with the AVN at the time the signal is received in at least a part of the memory area of the application framework (S320) .

In this case, the state information includes information about the last mode, as in the embodiment of FIG. 4 . Here, the information on the last mode is information on the display screen, and may include graphic elements.

The AVN system 1 receives, as a user input, a signal for supplying power to the vehicle (S330).

When power is supplied to the AVN system 1 again, the AVN system 1 uses the service agent to request the last screen, that is, the last display screen being displayed (S340), so that the last screen is subsequently played according to the request. It is possible to control the application framework (S350). After that, the AVN system 1 may obtain information on the display screen from the application framework (S360), and may or may not output the last screen based on the information (S370).

The AVN system 1 may check information about the display screen stored in at least a part of the memory area of the application framework using, for example, a service agent. When the information on the display screen is confirmed, the AVN system 1 prepares for screen switching to the confirmed screen using the service agent. When the AVN system 1 receives a host message generated based on the information on the display screen recorded in the application framework, the AVN system 1 switches the application layer to the display screen corresponding to the information.

Meanwhile, according to an embodiment, the host message delivered to the AVN system 1 may further include information on whether to display a display screen related to the infotainment application. For example, if a show state is determined by the AVN system 1 based on information on whether to display or not, the AVN system 1 may display the received information on the display screen. For another example, if the hide state is determined based on information on whether to display, the AVN system 1 does not display information on the received display screen.

For example, when the AVN-related application is an audio application for playing music, the AVN system 1 checks the content information (preferably, song information) that was being played before the power was cut off based on the running state information. and the music corresponding to the confirmed song information can be continuously played from a predetermined playback resumption point. Here, the predetermined playback resume point is determined based on information on the playback resume point included in the execution state information.

As another example, when the AVN-related application is a video application for playing an image, the AVN system 1 checks the content information (preferably, video information) that was being played before the power was cut off based on the running state information. Then, an image corresponding to the confirmed video information can be continuously reproduced from a predetermined playback restart point. Here, the predetermined playback resume point is determined based on information on the playback resume point included in the execution state information.

In some cases, when the application associated with the AVN is a streaming application, the AVN system 1 executes the streaming application again to provide a seamless streaming service. Send a streaming URL request with at least some of it. Here, the streaming platform may be composed of one or more computing devices, but is not limited thereto. In a preferred embodiment, at least a part of the execution state information transmitted to the streaming platform includes at least one of content information and information on a playback restart point.

On the other hand, each step of the method of providing a seamless AVN service provided by the vehicle having the above-described AVN system 1 will be schematically described as being supported by the AVN system 1 or one or more processors provided in the vehicle. may be

According to the present invention, even when the power of the vehicle is cut off, before the power supply to the AVN system 1 is stopped, the AVN system 1 stores the execution state information of the AVN-related application in the memory 10 by , there is an advantage that the AVN system 1 can seamlessly reproduce content that was played before the power was cut off using pre-stored execution state information when power is supplied to the vehicle again.

3 is a schematic flowchart for outputting last audio as an embodiment of the present invention.

Referring to FIG. 3 , the AVN system 1 receives, as a user input, a signal to cut off power to the vehicle ( S210 ).

When a signal to cut off the power to the vehicle is received, the AVN system 1 stores state information of the infotainment application associated with the AVN at the time the signal is received in at least a part of the memory area of the application framework (S220) .

The state information refers to execution state information. The running state information includes information about a state in which a corresponding (infotainment) application was running before or just before the power was cut off, that is, the last mode. When audio is being output immediately before the infotainment application is terminated, the application framework may store, for example, last play information about the audio. The last playback information includes information about a song being played and time information about the last playback time.

The AVN system 1 receives, as a user input, a signal for supplying power to the vehicle ( S230 ).

When power is supplied to the AVN system 1 again, the AVN system 1 requests the last audio using the service agent (S240), and controls the application framework so that the last audio is played continuously from the last playback point according to the request. It can be done (S250).

Last audio refers to audio corresponding to last reproduction information. The service agent checks the last play information stored in the memory area of a predetermined application framework, and supports the AVN system 1 so that the audio corresponding to the last play information is played externally. As a result, the AVN system 1 can seamlessly and continuously reproduce the last audio that was being played before the power was cut off.

In an embodiment of the present invention, in response to the infotainment application being executed before S210 , a host message informing that the infotainment service is ready may be transmitted from the application framework to the AVN system 1 by the service agent.

In another embodiment of the present invention, the embodiment related to audio may be equally applied to video.

On the other hand, the last mode of the infotainment application may include a display screen irrelevant to audio or video playback, so that the AVN system 1 can seamlessly service not only audio or video, but also the screen being displayed. In this case, the display screen output by the AVN system 1 will be described with reference to the flowchart of FIG. 5A .

4 is a schematic flowchart for outputting a last screen as another embodiment of the present invention.

Referring to FIG. 4 , the AVN system 1 receives, as a user input, a signal to cut off power to the vehicle ( S310 ).

When a signal to cut off the power to the vehicle is received, the AVN system 1 stores state information of the infotainment application associated with the AVN at the time the signal is received in at least a part of the memory area of the application framework (S320) .

In this case, the state information includes information about the last mode, as in the embodiment of FIG. 4 . Here, the information on the last mode is information on the display screen, and may include graphic elements.

The AVN system 1 receives, as a user input, a signal for supplying power to the vehicle (S330).

When power is supplied to the AVN system 1 again, the AVN system 1 uses the service agent to request the last screen, that is, the last display screen being displayed (S340), so that the last screen is subsequently played according to the request. It is possible to control the application framework (S350). After that, the AVN system 1 may obtain information on the display screen from the application framework (S360), and may or may not output the last screen based on the information (S370).

The AVN system 1 may check information about the display screen stored in at least a part of the memory area of the application framework using, for example, a service agent. When the information on the display screen is confirmed, the AVN system 1 prepares for screen switching to the confirmed screen using the service agent. When the AVN system 1 receives a host message generated based on the information on the display screen recorded in the application framework, the AVN system 1 switches the application layer to the display screen corresponding to the information.

Meanwhile, according to an embodiment, the host message delivered to the AVN system 1 may further include information on whether to display a display screen related to the infotainment application. For example, if a show state is determined by the AVN system 1 based on information on whether to display or not, the AVN system 1 may display the received information on the display screen. For another example, if the hide state is determined based on information on whether to display, the AVN system 1 does not display information on the received display screen.
