Abstract

Data of a telematics terminal is transmitted through an apparatus including a multimedia player, an audio interface, an embedded system, and a switch operatively connected between the audio interface and the embedded system. The multimedia player is configured to generate audio data, and the audio interface is configured to output audio data generated by the multimedia player. The switch is operatively connected between the audio interface and the embedded system, and is configured to selectively control the output of audio data or program data from the multimedia player.

4. The system according to claim 3, further comprising a storage unit configured to store the program data received through the audio interface.

5. The system according to claim 1, wherein the multimedia player is a compact disc (CD) player or a digital video disc (DVD) player.

6. The telematics terminal of claim 1, wherein the multimedia player is configured to allow a user to select the mode of operation.

7. The system of claim 1, wherein the telematics terminal system is a vehicle-mounted telematics terminal system.

8. The system of claim 7, wherein the at least one mode of operation for the play mode is associated with the output of the audio data and the other mode of operation for the data play mode is associated with the output of the program data.

9. The system of claim 1, wherein the telematics terminal system is configured to be physically installed in a vehicle.

10. A system for transmitting data of a telematics terminal comprising:

a multimedia player configured to;

generate audio data and program data, wherein the program data comprises split program data or compressed program data, the program data comprising one or more of program upgrade data, digital map data, and operation program data, and

operate in at least two modes of operation, wherein at least one mode of operation is a play mode and one mode of operation is a data play mode, wherein the play mode operates at a time that is different from a time of operation of the data play mode;

an audio interface configured to output audio data and program data generated by the multimedia player;

an embedded system for a telematics terminal;

a controller operatively connected to the multimedia player and configured to generate a first and second control signal, the first control signal generated in response to the multimedia player operating in play mode and the second control signal generated in response to the multimedia player operating in data play mode; and

a switch operatively connected between the audio interface and the embedded system, the switch configured to;

select one of the control signals from the controller,

receive the selected control signal,

responsive to receiving the first control signal as the selected control signal, control the audio interface to output the audio data from the audio interface, and

responsive to receiving the second control signal as the selected control signal, control the audio interface to output the program data from the audio interface.

11. The system according to claim 10, further comprising a storage unit within the embedded system, wherein the storage unit is configured to store the program data received through the audio interface.

12. The system according to claim 10, wherein the program data comprises program operating data of the embedded system.
