2 is a block diagram illustrating a mobile terminal according to one embodiment disclosed herein.

The mobile terminal 100 includes a wireless communication unit 110, an audio / video input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, A controller 170, a controller 180, a power supply 190, and the like. The components shown in FIG. 2 are not essential, and a mobile terminal having more or fewer components may be implemented.

Hereinafter, the components will be described in order.

The wireless communication unit 110 may include one or more modules for enabling wireless communication between the mobile terminal 100 and the wireless communication system or between the mobile terminal 100 and the network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short range communication module 114, and a location information module 115 .

The broadcast receiving module 111 receives a broadcast signal and / or broadcast related information from an external broadcast management server through a broadcast channel. The broadcast-related information may refer to a broadcast channel, a broadcast program, or information related to a broadcast service provider. The broadcast related information may also be provided through a mobile communication network. In this case, it may be received by the mobile communication module 112. The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

The mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. The wireless signal may include various types of data depending on a voice call signal, a video call signal or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and may be built in or externally attached to the mobile terminal 100. Wireless Internet technologies may include Wireless LAN (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like.

The short range communication module 114 refers to a module for short range communication. Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and the like can be used as a short range communication technology.

The short-range communication module 114 of the mobile terminal 100 according to an embodiment of the present disclosure may further include a near field communication (NFC) module (not shown). The NFC module may be disposed inside the housing. NFC modules typically include antennas located along the outside of the housing, capable of near field communication at relatively low data rates (e.g. 424 kb / s), and standards such as ISO 18092 or ISO 21481. Can follow. In some embodiments, the NFC module may also be capable of near field communication at relatively high transmission rates (eg, 560 Mbps).

In certain embodiments, communication using an NFC module can occur within a range of about 2-4 cm. Near range communication using the NFC module may occur through magnetic field induction, thus allowing the NFC module to communicate with other NFC devices or retrieve information from tags with radio frequency identification (RFID) circuitry. Magnetic field induction may also cause the NFC module to "wake up" or induce other NFC devices in passive or sleep mode to active mode.

The mobile terminal 100 enables communication in peer-to-peer mode for receiving identification information of the digital media renderer 300 from the digital media controller 200. The NFC module can be directed to an "host" or active mode, which itself generates an RF field, and to an active state to perform the transmission or reception of data upon detection of an RF field generated by another NFC device. The mobile terminal 100 may be configured to switch between a passive mode or a "wake-on-NFC" mode.

For example, when the mobile terminal 100 and the digital media controller 200 are placed within close proximity (eg, generally 2-4 cm) close enough to facilitate the establishment of the NFC connection 700, The RF field generated by the digital media controller 200 may induce the mobile terminal 100 to switch to an active mode of operation, thus NFC connection 700 between the mobile terminal 100 and the digital media controller 200. Can be set. Accordingly, identification information of the digital media renderer 300 may be transmitted and received by the mobile terminal 100 through the established connection.

In one embodiment, prior to initiating the near field communication connection, the mobile terminal 100 may be in manual or "wake on NFC" mode. While in the passive state, the NFC module, which may be included in the mobile terminal 100, may remain inactive until the NFC module detects NFC transmission from an external device, such as the digital media controller 200.

For example, when the digital media controller 200 operates to transmit identification information of the digital media renderer 300, the NFC module of the mobile terminal 100 may switch to an active or host mode. While in host mode, digital media controller 200 may periodically emit NFC communication signals to look for other NFC devices, such as mobile terminal 100, within an appropriate range to assist NFC connection 700.

For example, when the mobile terminal 100 and the digital media controller 200 are placed within a range suitable for establishing the NFC connection 700, the establishment of the connection can be initiated. While the digital media controller 200 is operating in the host mode, the digital media controller 200 may periodically emit ping messages for detecting the mobile terminal 100. The mobile terminal 100 can receive ping messages, so that the mobile terminal 100 located within the digital media controller 200 wakes up upon detection of NFC transmission (e.g., wake on NFC), from passive mode to active mode. To switch to Thus, when the near field communication module of the mobile terminal 100 is powered on and driven, it may respond to the ping message by sending a confirmation message that the digital media controller 200 can receive, thus establishing a connection (or initiating handshake). ) Can be completed.

Following this connection establishment, the mobile terminal 100 and the digital media controller 200 may exchange device profiles. The device profiles may include various information regarding the functions available on the mobile terminal 100 and the digital media controller 200. For example, device profiles may be represented by any suitable form of data messages, including extended markup language (XML), which may indicate device name, serial number, owner name, device type, as well as any other type of identifying information. Can be expressed. For example, the additional identification information may include the name of a service provider, such as a network or cellular telephone service provider, which may be associated with each of the devices, for example. The device profiles may further include information related to the capabilities of the mobile terminal 100 or the digital media controller 200 by indicating which applications, drivers or services can be installed on each device.

In addition, the mobile terminal 100 and the digital media controller 200 may also exchange authentication information available on each device. Thus, once the NFC connection 700 is established and device profiles and encryption capabilities are exchanged, information necessary for content sharing can be exchanged between the mobile terminal 100 and the digital media controller 200.

The position information module 115 is a module for obtaining the position of the mobile terminal, and a representative example thereof is a Global Position System (GPS) module.
