Also, when the driver is sensitive to noise generated while playing multimedia content in the navigation device, the navigation device interferes with driving. It is also possible to use devices using near field communication such as Bluetooth headphones.

In addition, when the user of the rental car arrives at the destination and the rental car user needs to get off, the rental car user uses the storage function included in the navigation device to transmit only the data of the unplayed portion of the same multimedia content when the rental car user boards again. Stores information about the played part and provides only the part which is not played by the user of the car afterwards.

6 is a flowchart illustrating a method of recommending multimedia content to a car rental user according to an embodiment of the present invention.

In order to recommend the multimedia content to the passengers of the vehicle, it may be recommended in consideration of various contents such as the contents of the video, the playing time of the video, and the quality of the video.

For example, the estimated time of arrival may be estimated based on the destination information input to the navigation, and the multimedia content having the video playback time less than the estimated time of arrival may be recommended to the passenger of the vehicle.

In addition, since the data transmission amount according to the image quality of the streaming service is different, the passenger of the vehicle can select the image quality and pay differential charges accordingly.

For example, the video content may select one of the genre of the movie according to the taste of the vehicle occupant by the user, and may recommend it to the vehicle occupant based on the genre, and recommend the music video to the vehicle occupant who wants to listen to the music. .

Based on the destination information of the vehicle, the multimedia content for completing the streaming service may be recommended until the destination is reached (S610).

The primary purpose of the vehicle may be to move to a destination rather than to enjoy a multimedia content service. Therefore, when the vehicle arrives at the destination, the passenger of the vehicle often needs to get off the vehicle while receiving the multimedia content. If the vehicle is provided with contents that can complete the streaming service before arriving at the destination, it is possible to get off after receiving all the multimedia contents. Therefore, the multimedia contents are recommended based on the playing time information of the multimedia contents and the estimated time of arrival of the vehicle. I can receive it.

Step 610 may be omitted when the passenger of the vehicle receives the multimedia content streaming service regardless of the estimated time of arrival. For example, when you receive a movie streaming service, you can store the information about the part where streaming was stopped when you did not receive all the movie streaming service in the storage unit and then receive the streaming service again from where you left off the next time you board the vehicle. .

Next, after receiving the category of the multimedia content to receive the streaming service, the multimedia content included in the selected category may be received (S620).

For example, when a passenger of a vehicle selects a movie from among the multimedia categories, the passenger may be provided with a list of movies classified by genre so that the passenger may select content according to the genre of the movie.

The occupant of the vehicle may select one of the divided categories and select one of the multimedia contents included in the selected category.

After receiving the multimedia content, the user may be selected to provide the selected multimedia content in what quality (S630).

A vehicle according to an exemplary embodiment of the present invention may provide multimedia contents while a passenger is in a business vehicle as a sales vehicle such as a car, a highway bus, or a taxi. Passengers shall pay the bill using the multimedia contents to the operating vehicle operator when getting off the vehicle or returning the vehicle.

The charge for using multimedia content may vary depending on the amount of data transmission and reception. Therefore, the use of multimedia content charges in accordance with the quality of the streaming service may occur differently, so that the passenger of the vehicle may select a quality of the streaming service to widen the selection.

Therefore, the occupant of the vehicle may select which image quality the multimedia content is to be streamed. For example, by providing a choice of various image quality, such as QCIF, CIF, SDTV, HDTV, etc., the choice of occupants of the vehicle can be expanded.

The above-described order of receiving a predetermined selection for streaming the multimedia content to the passenger of the vehicle is not limited to the above-described order of the flowchart. For example, it is possible to change the order of recommending the content to the passenger of the vehicle, and to select the image quality of the video first by the passenger of the vehicle, and to select the playback time and the content of the video later.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
