Broadcast signal processing system and method for searching storage device thereof

A broadcast signal processing system, the broadcast signal processing system comprising:

• a receiving unit configured to receive a broadcast signal;
• a decoding unit configured to decode the broadcast signal received by the receiving unit;
• a display unit configured to display broadcast content according to the broadcast signal decoded by the decoding unit;
• an interface unit configured to communicate with a storage device through a wired network or a wireless network;
• a first control unit configured to control connection to the storage device through the interface unit using a network protocol for searching the storage device when the storage device is connected to the network;
• and
• a second control unit configured to control storage of the broadcast signal decoded by the decoding unit or playback of content stored in the storage device by the display unit, when the storage device is connected to the network according to control of the first control unit,
• wherein when a request for displaying a storage device currently connected with the broadcasting signal processing system is inputted through a user interface, the display unit displays the connection information for a previously connected storage device through the interface unit, and
• when the previously connected storage device is not currently connected based on the connection information, the first control unit performs a search function, the search function searching a new storage device through the network by the interface unit using a network protocol, the new storage device being capable of currently connecting with the broadcasting signal processing system through the network by the interface unit, and then the display unit displays the second control unit controls so that search information for the new storage device searched through the network by the interface unit.

A method for searching a storage device, the method comprising:

• receiving, through a user interface, a request for displaying a storage device currently connected with a broadcasting signal processing system;
• providing, on a display unit, the connection information for a previously connected storage device through the interface unit;
• receiving, through the user interface, a selection signal for selecting a storage device as to previously connected storage devices in the provided connection information from a user;
• performing a search function when a selected storage is not currently connected in accordance with the selection signal, the search function searching a new storage device through a network using a network protocol, the new storage device being capable of currently connecting with the broadcasting signal processing system through the network;
• displaying, on the display unit, the search information for the new storage device searched through the network;
• and
• accessing the new storage device according to the search function, and storing a broadcast signal in the new storage device or playing content stored in the new storage device when the new storage device is connected.
