The communication connection request signal may be transmitted from the mobile terminal 200 to the AVN 100 or from the AVN 100 to the mobile terminal 200 when the wired or wireless interface between the mobile terminal 200 and the AVN 100 is physically connected. 200).

Thereafter, authentication is performed to form a communication link between the AVN 100 and the mobile terminal 200 (S103).

The communication link between the AVN 100 and the mobile terminal 200 in the video synchronizing method through the interworking of the mobile terminal 200 in the AVN 100 according to an embodiment of the present invention may be a universal serial bus (USB) ) May be a wired connection.

The communication link between the AVN 100 and the mobile terminal 200 may be a communication link such as a local area wireless communication (NFC), an infrared communication (IrDA), a DLNA (Digital Living Network Alliance), a WiFi, (Zigbee).

The NFC (Near Field Communication) is a non-contact type short-range wireless communication module using a frequency band of 13.56 MHz as one of RFID, and transmits data between terminals at a distance of 10 cm. This is an extended concept in existing RFID, and it is possible to operate a terminal with tag embedded in ACTIVE mode, so that not only a function as a tag but also a reader (reader) for reading a tag, a writer Function, and P2P between the terminal and the terminal is possible.

Also, in the case of the wireless connection, the communication connection request and authentication process may be applied to a normal device-to-device pairing process according to the wireless communication protocol.

When the communication connection is Bluetooth, it can perform authentication, PIN code, and encryption. The authentication is a process of setting whether to transmit or receive a PIN code (pass key) for connection with another Bluetooth device. The PIN code is the same as a password of a kind, And encryption is a process for encrypting data exchanged between Bluetooth devices.

When the mobile 200 and the AVN 100 are paired using the Bluetooth as described above, when the AVN 100 searches for peripheral devices and the mobile terminal 200 is searched within a predetermined distance supported by the Bluetooth module , The mobile terminal 200 can be connected after receiving and transmitting the PIN code.
