1 and 2 are flowcharts illustrating a method for establishing a host device connection according to an embodiment of the present invention.

Referring to FIG. 1, first, a first host is connected (S110). In this case, the first host may be connected through one of at least one external device interface of the first host.

The first host and the second host to be described later are digital devices such as a computer, an image device, an audio device, a portable device, etc., and mean a digital device that can be connected to another host through a wired / wireless interface. Accordingly, the first host and the second host include at least one wired or wireless interface, that is, an external device interface.

In performing the first host connection step (S110) and the second host connection step (S130) to be described later, other than the interface selected in the connection interface selection step (S150) between the first host and the second host which will be described later. It may be connected to the first host and the second host through an interface.

However, even if there are a plurality of wired / wireless ports for the same interface or only one wired / wireless port exists for the same interface, the host device connection establishment method according to an embodiment of the present invention is executed by changing the time difference. The connection process and the connection process between the first host and the second host may be performed, but are not necessarily limited to using different interfaces.

For example, the wired / wireless interface or the external device interface may include Universal Serial Bus (USB), FireWire, External Serial ATA (eSATA), Enhanced IDE (EIDE), PS / 2, Local Area Network (LAN), and Bluetooth (Bluetooth). , At least one of a wireless LAN and a Zigbee. Hereinafter, the method for establishing a host device connection according to an embodiment of the present invention is executed by being connected to the USB interface of the first host and the second host to establish a connection between the first host and the second host. .

Next, first information about at least one external device interface of the first host is collected (S120). In this case, as described above in connection with the first host connection step (S110), any one interface of the first host may be collected. Information about at least one external device interface of the first host may be collected.

The first information about the at least one external device interface and the second information to be described later may include system information, system profiles, system configuration, and system properties of the first host and the second host. It exists as part of system-related information such as (System Properties), Device Management Information, and Registry, and is implemented in the form of a structured data structure or database.

The first information and the second information may be a non-volatile memory such as a ROM (Read Only Memory) included in the first host and the second host, or a volatile memory such as a random access memory. ) Can be stored. For example, when a command is sent to the first host or the second host to request the first information or the second information through the USB interface, the first host or the second host is stored in its memory in response to the command. The first information or the second information can be sent.

At least one of the first information and the second information sent by the first host and the second host may be stored in a separate storage space and used to select the connection interface by comparing the first information and the second information with each other.

Next, it is connected to the second host (S130), in which case it may be disconnected from the first host and connected to the second host, and connected to the second host through any one interface of at least one external device interface of the second host. Can be.

In particular, in providing the connection interface list to the user, the connection interface list may be displayed on a separate display device.

For example, as in the above-described example, the host device connection establishment method is executed by being connected to the USB interface of the first host and the second host, and the first host supports the USB, FireWire, Bluetooth, and WLAN interfaces, 2 If the host supports USB, FireWire, Bluetooth, or WLAN interfaces, and no USB cable or FireWire cable is connected between the first host and the second host, the user can choose between the Bluetooth and FireWire The wireless LAN may be displayed and either connection interface may be selected by a user's input.

Referring back to FIG. 1, a connection is established between the first host and the second host by using the next selected connection interface (S160). In this case, system information, system profile, system setting, system property, device management information, or registry of at least one of the first host and the second host may be modified. The system information of both the first host and the second host is modified unless the connection establishment can be completed simply by modifying the system information on either the first host or the second host.

For example, when Bluetooth is selected as a connection interface or a connection interface by a user selection, the Bluetooth profile to be used for transmission is automatically set according to the device characteristics of the first host and the second host, and the device is configured to work with the Bluetooth stack. You can customize the settings.

For another example, when the WLAN is selected as a connection interface or a connection interface by user selection, a connection between the first host and the second host may be established by adjusting settings of an IP address, a port, and a firewall.

In order to establish a connection between the first host and the second host, after modifying system information and the like, executing, activating, restarting or resetting a service, function or application related to at least one of the first host and the second host. (Reset) or at least one of the first host and the second host may be reset or reset.

If it is separated from the first host in the second host connection step (S130), in establishing a connection between the first host and the second host, establishing a connection of the second host to the first host using the selected connection interface. After reconnecting to the first host, a connection of the first host to the second host may be established using the selected connection interface. In this case, when reconnected with the first host, it may be separated from the second host.
