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.
