A method of manufacturing a porous metal foam having pores of nano size includes: manufacturing a porous polymer foam containing pores of nano size; and coating metal on the porous polymer foam through electroless plating. The present invention provides porous metal foams which contains nano-sized pores and hence, their specific surface area is maximized owing to the regularly-patterned nanoporous structure formed inside.

Method of manufacturing porous metal foam

A video signal processing apparatus, comprises: a display unit; an user interface (UI) generating unit that generates a UI including a channel information array in which a plurality of channel informations are arranged to be displayed to the display unit; a user inputting unit that receives a first moving instruction and a second moving instruction for moving the channel information array, the second moving instruction including a position information about moving of the channel information array; and a control unit that controls the UI generating unit so that the channel informations arranged in the channel information array can move one by one if the first moving instruction is received, and the channel informations arranged in the channel information array can move in an manner that corresponds to the position information if the second moving instruction is received.

Video signal processing apparatus and control method thereof

Disclosed is a system and a method for provisioning service flows in broadband wireless access communication. In a broadband wireless access communication system, if a base station receives a registration request message from a mobile station, and if the base station inserts information about service flows to be provisioned by a base station into a registration response message and transmits the registration response message to the mobile station after the registration request message is received, the mobile station determines if the mobile station transits into a normal operation mode corresponding to the information and exactly recognizes a time point at which the mobile station goes into the normal operation mode.

Disclosed is a system and method for transmitting and receiving hybrid automatic repeat request (HARQ) buffer capability information in a broadband wireless access communication system. According to the system and method, a mobile station detects its own HARQ buffer capacity, and transmits a message including information about the detected HARQ buffer capability to a base station. The base station receives the message and determines the amount of a transmission signal to be allocated to the mobile station based on the HARQ buffer capability, so that it is possible to operate a HARQ scheme in accordance with the HARQ buffer capability of the mobile station.

A display apparatus and a control method are provided in which a size menu item is changed, when the menu item is directed by a user. A display apparatus includes a user input part; a menu generator generating a user menu including at least one or more items; a display part displayed with the user menu generated from the menu generator; and a controller controlling the menu generator so that a size of a directed item according to an operation of the user input part among the items of the user menu displayed at the display part is reduced into a predetermined size and then is returned to an original size.

Display apparatus and control method for displaying user menu

Disclosed are methods for transmitting/receiving a traffic indication message in a wireless communication system. In the wireless communication system, a base station (BS) groups a plurality of sleep mode IDs, and broadcasts a traffic indication message that includes first bitmap information indicating whether traffic corresponding to respective the sleep mode ID groups exists as well as second bitmap information indicating whether traffic indicators with respect to the respective sleep mode IDs that belong to the sleep mode ID groups exists. A mobile subscriber station (MS) which is allocated with any one of the plurality of sleep mode IDs, determines whether the traffic occurs in the sleep mode ID group to which the MS itself belongs using the first bitmap information if the MS receives the traffic indication message, and checks the traffic indicator of the terminal itself using the second bitmap information if the traffic occurs in the sleep mode ID group to which the MS belongs.
