Abstract

A data output system for a mobile device and an associated method for outputting data of a mobile device are provided. The data output system for a mobile device can deliver data output from the mobile device to an embedded system, and display the data on a display screen of the embedded system. When the data output system is implemented in a mobile phone, a navigation map of the mobile phone can be shown by a large screen of the embedded system, and the embedded system can be utilized as a phone interface.

Claims

1. A data output system, for externally connecting to a mobile device, comprising:

an embedded system, comprising;

an output module; and

a processing module, coupled to the output module, for processing digital data transmitted from the mobile device and sending resulting processed digital data to the output module for output.

2. The data output system as claimed in claim 1, wherein the digital data transmitted from the mobile device comprises a display data, an audio signal or a control signal of a user interface of the mobile device.

3. The data output system as claimed in claim 1, wherein the embedded system further serves as a control interface of the mobile device, and the processing module further feeds back a control signal to the mobile device to control operations of the mobile device when the output module outputs the processed digital data.

4. The data output system as claimed in claim 1, wherein the embedded system further comprises a first connecting port, via which the processing module is coupled to a second connecting port of the mobile device using a transmission wire.

5. The data output system as claimed in claim 4, further comprising a converting circuit, coupled between the first connecting port and the second connecting port of the mobile device, for converting data transmission specifications between the embedded system and the mobile device.

6. The data output system as claimed in claim 1, wherein the processing module receives the digital data from the mobile device via wireless transmission.

7. The data output system as claimed in claim 6, further comprising:

a converting circuit, having a wireless transmission interface, coupled to a second connecting port of the mobile device, for performing wireless transmission with the embedded system to transmit the digital data to the processing module.

8. A method for outputting data of a mobile device, comprising steps of:

transmitting digital data of the mobile device to an embedded system; and

processing the digital data using the embedded system, and outputting resulting processed digital data using an output module of the embedded system.

9. The method as claimed in claim 8, wherein the digital data comprises display data, an audio signal or a control signal of a user interface of the mobile device.

10. The method as claimed in claim 8, the embedded system further serving as a control interface of the mobile device, the method further comprising a step of:

feeding back a control signal to the mobile device to control operations of the mobile device when the output module outputs the processed digital data.

11. The method as claimed in claim 8, wherein the embedded system further comprises a first connecting port, and the step of transmitting the digital data of the mobile device to the embedded system comprises steps of:

coupling a second connecting port of the mobile device and the first connecting port of the embedded system using a transmission wire; and

transmitting the digital data via the transmission wire to the embedded system.

12. The method as claimed in claim 11, wherein the step of transmitting the digital data via the transmission wire to the embedded system comprises a step of:

converting data transmission specifications between the embedded system and the mobile device.

13. The method as claimed in claim 8, wherein the step of transmitting the digital data via the transmission wire to the embedded system comprises transmitting the digital data via a wireless transmission interface to the embedded system.

14. The method as claimed in claim 13, wherein the step of transmitting the digital data via the transmission wire to the embedded system comprises a step of:

converting data transmission specifications between the embedded system and the mobile device, and performing wireless transmission with the embedded system using the wireless transmission interface.
