BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a block diagram of an audio output management system according to an embodiment of the present invention.

The audio output management system includes a vehicle multimedia apparatus 100 and a mobile device 200. The vehicle multimedia apparatus 100 is a vehicle head unit that not only provides an audio / video function but also a navigation function. The vehicle multimedia apparatus 100 includes a Bluetooth module for Bluetooth communication. The mobile device 200 may be a smart phone and includes a Bluetooth module for Bluetooth communication with the vehicle multimedia apparatus 100. The mobile device 200 may be connected to the vehicle multimedia apparatus 100 via Bluetooth, or may be physically connected through a data cable. The mobile device 200 may output an audio stream to a Bluetooth module and transmit the audio stream to the vehicle multimedia apparatus 100. The mobile device 200 may output the audio stream to a terminal connected with a data cable and transmit the audio stream to the vehicle multimedia apparatus 100. An example of a mobile device with this capability is the iPhone.

2 is a block diagram of a vehicle multimedia apparatus according to an embodiment of the present invention.

As shown, the vehicle multimedia apparatus 100 includes a user input / output unit 110, a cable connection unit 120, a communication unit 130, an audio reproduction unit 140, and a controller 150. The user input / output unit 110 is a component for user input and output, and may be a touch screen capable of a touch input as well as a screen output. The user may select a desired audio mode through the user input / output unit 110. For example, the user can select the desired mode between iPod mode and Bluetooth mode. The cable connection unit 120 is a terminal for data cable connection with the mobile device 200. In one embodiment, the cable connection 120 is a USB terminal. The communication unit 130 is a configuration for Bluetooth communication with the mobile device 200. The audio reproducing unit 140 is a well-known configuration for reproducing and outputting the audio stream transmitted from the mobile device 200 to the outside. The controller 150 is a controller that controls the overall vehicle multimedia apparatus and may be a central processing unit.

3 is a flowchart illustrating an audio output management method according to an exemplary embodiment of the present invention.

In FIG. 3, it is assumed that the vehicle multimedia apparatus 100 and the mobile device 200 are connected by a data cable, and the Bluetooth pairing is not performed. The controller 150 receives the audio stream output from the mobile device 200 through the cable connection unit 120 (S310). When the controller 150 transmits the received audio stream to the audio reproducing unit 140, the audio reproducing unit 140 reproduces and outputs the audio stream (S320). In this situation, the controller 150 proceeds with Bluetooth pairing with the mobile device 200 through the communication unit 130. When it is determined that the mobile device 200 is a designated model during the Bluetooth pairing process, the Bluetooth audio profile A2DP is used. (Advanced Audio Distribution Profile) setting is excluded (S330). Herein, the controller 150 may check whether the designated model is, for example, an iPhone, through the model information transmitted from the mobile device 200 during Bluetooth pairing. Therefore, since the A2DP setting is not made even when the Bluetooth pairing is completed, the mobile device 200 maintains the audio stream output direction.
