Abstract: An air conditioner includes a discharge blade configured to move between a guide position at which a direction of air blown from a blower fan and discharged to an outlet is controlled, and a closing position at which the outlet is closed, wherein the discharge blade includes a plurality of blade holes through which the air is discharged through the discharge blade at the closing position, wherein the discharge blade moves between the guide position and the closing position and controls an air flow from the blower fan to a discharge plate or the outlet. Through this configuration, an air flow discharged to the outside of the housing can be controlled by operation of the discharge blade.

Abstract: An electronic apparatus includes a communicator; and a processor configured to: transmit a message including a communication connection order among a plurality of terminals to the plurality of terminals through the communicator, and control the communicator to sequentially perform connections with the plurality of terminals corresponding to association requests respectively received from the plurality of terminals after transmitting the message.

Abstract: An electronic apparatus is provided. The electronic device includes a plurality of multi-band antennas configured to transmit and receive data to and from an access point, and a processor configured to transmit and receive predetermined data to and from the access point through each of the plurality of multi-band antennas and calculate a data transmission rate of each of the plurality of multi-band antennas, and to select at least one multi-band antenna for transmitting and receiving data to and from the access point based on the calculated data transmission rates.

Abstract: An apparatus and method for changing a channel in a digital broadcasting system are provided. The apparatus includes: a digital broadcast server for transmitting a multiplexed stream obtained by multiplexing at least one down broadcast data, and transmitting up broadcast data and at least one difference broadcast data; and a set-top box for accessing a channel over which the multiplexed stream is transmitted to perceive a down broadcasting PID (program identification) set for transmitting at least one down broadcast data contained in the multiplexed stream, upsizing and outputting down broadcast data having a down broadcasting PID corresponding to selected channel information from the multiplexed stream when a user selects a certain channel, summing difference broadcast data corresponding to a difference broadcasting PID and broadcast data obtained by upsizing the down broadcast data corresponding to the channel information, and outputting the result.
