1 is a block diagram showing a configuration of an embodiment of a head unit control apparatus according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The terms used throughout the specification of the present invention have been defined in consideration of the functions of the embodiments of the present invention and can be sufficiently modified according to the intentions and customs of the user or operator. It should be based on the contents of.

1 is a block diagram showing a configuration of an embodiment of a head unit control apparatus according to the present invention. The head unit control apparatus 100 according to the present invention is implemented in the form of a peripheral device physically connected to the head unit 200 of the vehicle and includes a mobile communication terminal 300 connected to the head unit control apparatus 100 in short- A digital broadcasting and mirroring integrated control operation is performed.

1, a head unit control apparatus 100 according to the present invention includes a wireless broadcast receiving unit 110, a short range wireless communication unit 120, a selection switch 130, a DEMUX 140, A head unit interface 150, and a control unit 160. [

The wireless broadcast receiver 110 receives a wireless digital broadcast signal. For example, the wireless broadcast receiver 110 may process an RF baseband signal for wireless digital broadcasting received through an antenna (not shown) to tune and output a broadcast signal of a selected channel frequency.

The short-range wireless communication unit 120 receives a mirroring signal from the mobile communication terminal. For example, the short-range wireless communication unit 120 may be implemented to perform short-range wireless communication using WIFI, Bluetooth, beacon, Zigbee, or the like.

In this case, mirroring refers to a technique of outputting the same output as the video or audio output of the mobile communication terminal through the auxiliary device. Since the mirroring process is a conventional technology known before the application, which is performed on the mobile communication terminal side, a detailed description thereof will be omitted.

The selection switch 130 selects one of a wireless digital broadcasting signal received by the wireless broadcast receiving unit 110 and a mirroring signal received by the short-range wireless communication unit 120.

The demultiplexer 140 demultiplexes the video signal and the audio signal from the radio digital broadcasting signal or the mirroring signal selected by the selection switch 130. Since the wireless digital broadcasting signal or the mirroring signal is a signal in which a video signal and an audio signal are multiplexed, the signal is demultiplexed through the demultiplexer 140 to separate a video signal and an audio signal.

The head unit interface 150 is connected to a head unit of the vehicle and outputs a video signal and an audio signal to the head unit. For example, the head unit interface 150 may be an HDMI (High Definition Multimedia Interface).

The control unit 160 performs digital broadcasting and mirroring integrated control including selection of a wireless digital broadcasting signal or a mirroring signal. At this time, the controller 160 may provide an application for integrated control of digital broadcasting and mirroring to the mobile communication terminal through the short-range wireless communication unit 120, and may perform integrated control of digital broadcasting and mirroring through the application.

The video signal and the audio signal output through the head unit interface 150 are reproduced through the head unit so that wireless digital broadcasting or mobile communication terminal mirroring is performed through the head unit.

Therefore, according to the present invention, the present invention can be implemented as a single device that performs digital broadcast and mirroring integrated control by connecting to a head unit of a vehicle as a peripheral device without implementing digital broadcasting and mirroring functions, The digital broadcasting and mirroring function can be provided to the head unit of the vehicle at a cost.

According to a further aspect of the present invention, the head unit control apparatus 100 may further include a video codec 170 and an audio codec 180. The video codec 170 decodes the video signal separated by the demultiplexer 140. The audio codec 180 decodes an audio signal separated by the demultiplexer 140.

Since the video signal and the audio signal are encoded and transmitted for fast transmission on the transmission side, they are compressed and transmitted by the video CODEC 170 and the audio CODEC 180 of the head unit control device 100, And decodes the video signal and the audio signal.

According to a further aspect of the present invention, the head unit control apparatus 100 may further include a packet processing unit 190. [ The packet processor 190 separates a video packet and an audio packet from a Miracast stream.

That is, in this embodiment, when a Miracast stream, which is a transmission technique capable of sharing voice with the same screen through the WiFi, is received through the short-range wireless communication unit 120, the packet is transmitted from the mirrorcast stream through the packet processing unit 190 A video packet and an audio packet are extracted.

On the other hand, according to a further aspect of the present invention, the head unit control apparatus 100 may further include a power interface 192. The power interface 192 is connected to the head unit, and receives power from the head unit. For example, the power interface may be a Universal Serial Bus (USB) interface.

That is, this embodiment enables the head unit control device 100 to be provided with a separate power source, and to receive the driving power of the head unit control device 100 from the head unit, thereby miniaturizing the device.

As described above, the present invention can be implemented as a single device for performing digital broadcasting and mirroring integrated control by connecting to a head unit of a vehicle as a peripheral device without implementing digital broadcasting and mirroring functions, The digital broadcasting and the mirroring function can be provided to the head unit of the vehicle, so that the object of the present invention can be achieved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill 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 by the appended claims. .

The present invention is industrially applicable in the field of multimedia control technology and its application technology.
