4 is a flowchart schematically illustrating a flow of a preferred channel storage method according to the present invention.

The controller 180 sets at least one preferred channel for the external display device 200 (S410). The memory 160 stores the set preferred channel (S420). The wireless communication unit 110 transmits the set preferred channel to the external display device 200 (S430). The controller 180 controls to store the transmitted preferred channel as the preferred channel for each terminal in the external display device (S440).

The external display device referred to in the present invention refers to a device that plays or displays various kinds of files such as media files. For example, the external display device includes various devices such as a mobile terminal having a display module, a PDP, a tablet PC, etc., as well as a display-only device such as a TV and a monitor.

The object reproduced by the external display device is not limited to the type thereof, and may include, for example, an over-the-air broadcasting program, various programs received from the Internet, an audio program, and the like.

An external display device such as a TV can generally receive and display a broadcast program through various broadcast channels. Such a broadcast channel may include a satellite channel and a terrestrial channel. In addition, the external display device may store a specific broadcast channel in a memory of the external display device.

If there are many broadcasters as of now, there are a lot of broadcast channels for each broadcaster to transmit a broadcast program. For example, if a cable broadcast channel is included as well as an airwave channel, there is a limit in that the user memorizes the broadcast channel. Accordingly, a specific broadcast channel that is frequently used or desired by a user among a large number of broadcast channels is set as a preferred channel.

Current external display devices provide user convenience by storing a preferred channel in a memory of the external display device. However, when the number of preferred channels increases, especially when the family members use the same external display device, the number of favorite channels increases rapidly when each family member sets the preferred channel. There is a similar problem.

Recent mobile terminals can provide various functions. Among these various functions include a function for controlling the external display device through the terminal. For example, various controls such as power or volume of an external display device, channel switching, and playback of a media file are enabled through the terminal.
