Abstract

The invention relates to the transmission of multimedia data, which is to be output, from a computer device to a vehicle multimedia device. The vehicle multimedia device has a control device which is designed to determine a piece of vehicle status information in order to transmit said information to the computer device. On the basis of the vehicle status information, the computer device generates release data which determines to what extent the multimedia data is to be output. The computer device transmits the multimedia data and the release data to the vehicle multimedia device, which multimedia device outputs, by means of an output device, the maximum multimedia data to the extent defined by the release data.

Claims

1. A vehicle multimedia device, having:

an output device for outputting multimedia data;

a control device for controlling the output device;

wherein the control device is designed to determine a piece of vehicle status information;

wherein the control device is designed to send the vehicle status information to a computer device coupled to the vehicle multimedia device;

wherein the control device is designed to receive from the computer device multimedia data that are to be output and clearance data that stipulate the scope in which the multimedia data that are to be output can be output; and

wherein the control device is designed to output, by means of the output device, the multimedia data that are to be output at most in the scope stipulated by the clearance data.

2. The vehicle multimedia device as claimed in claim 1,

wherein the output device is a screen and

wherein the multimedia data sent by the computer device coupled to the vehicle multimedia device define an image that is to be reproduced on the screen.

3. The vehicle multimedia device as claimed in claim 1,

wherein the control device is designed to output, by means of the output device, for a predefined period after the clearance data are received, the multimedia data that are to be output at most in the scope stipulated by the clearance data;

and

wherein the control device is designed to no longer output the multimedia data that are to be output after the predefined period has elapsed if no new clearance data have been received between the clearance data being received and the predefined period elapsing.

4. The vehicle multimedia device as claimed in claim 1,

wherein the control device is designed to receive encrypted and/or signed clearance data from the coupled computer device;

wherein the control device is designed to decrypt the clearance data and to check a signature of the clearance data; and

wherein the control device is designed to output the multimedia data only if the clearance data have been successfully decrypted and if the signature thereof has been successfully checked.

5. The vehicle multimedia device as claimed in claim 1, wherein the vehicle status information is selected from the group consisting of a speed of the vehicle, a tank content of the vehicle, a current traffic density in the vehicle surroundings, information pertaining to light conditions, a complexity of a vehicle path ahead, a number of turns in a vehicle path ahead, traffic rules to be taken into consideration by the vehicle and any combination of these.

6. A vehicle multimedia system, having:

a vehicle multimedia device as claimed in one of the preceding claims;

a computer device;

wherein the vehicle multimedia device and the computer device are couplable to one another;

wherein the computer device is designed to receive the vehicle status information of the vehicle multimedia device;

wherein the computer device is designed to produce the multimedia data that are to be output;

wherein the computer device is designed to take the vehicle status information as a basis for producing the clearance data; and

wherein the computer device is designed to transmit the multimedia data that are to be output and the vehicle status information to the vehicle multimedia device.

7. The vehicle multimedia system as claimed in claim 6,

wherein the computer device has a memory unit;

and

wherein the memory unit stores a set of rules in which, for different vehicle status information and for different types of multimedia data, there is a definition of the scope in which the different types of multimedia data can each be output on the basis of a piece of vehicle status information.

8. The vehicle multimedia system as claimed in claim 6,

wherein the computer device is a portable device;

wherein the computer device has a screen; and

wherein the multimedia data define an image that is presented on the screen of the computer device and that is to be reproduced on a screen of the output device of the vehicle multimedia device.

14. The vehicle multimedia device as claimed in claim 2,

wherein the control device is designed to output, by means of the output device, for a predefined period after the clearance data are received, the multimedia data that are to be output at most in the scope stipulated by the clearance data;

and

wherein the control device is designed to no longer output the multimedia data that are to be output after the predefined period has elapsed if no new clearance data have been received between the clearance data being received and the predefined period elapsing.

15. The vehicle multimedia device as claimed in claim 14,

wherein the control device is designed to receive encrypted and/or signed clearance data from the coupled computer device;

wherein the control device is designed to decrypt the clearance data and to check a signature of the clearance data; and

wherein the control device is designed to output the multimedia data only if the clearance data have been successfully decrypted and if the signature thereof has been successfully checked.

16. The vehicle multimedia device as claimed in claim 15, wherein the vehicle status information is selected from the group consisting of a speed of the vehicle, a tank content of the vehicle, a current traffic density in the vehicle surroundings, information pertaining to light conditions, a complexity of a vehicle path ahead, a number of turns in a vehicle path ahead, traffic rules to be taken into consideration by the vehicle and any combination of these.

17. The vehicle multimedia system as claimed in claim 7,

wherein the computer device is a portable device;

wherein the computer device has a screen; and

wherein the multimedia data define an image that is presented on the screen of the computer device and that is to be reproduced on a screen of the output device of the vehicle multimedia device.

9. (canceled)

10. A method for transmitting multimedia data that are to be output by means of an output device of a vehicle multimedia device from a computer device to the vehicle multimedia device coupled to the computer device, the method comprising:

receiving a piece of vehicle status information from the vehicle multimedia device by the computer device;

sending multimedia data that are to be output, to the vehicle multimedia device; and

sending clearance data that stipulate the scope in which the multimedia data that are to be output can be output, to the vehicle multimedia device.
