A power management system of a set-top box includes a display module, connected to the set-top box via a video terminal, for transmitting video terminal information, produced by video terminal selection of a user, to the set-top box; and the set-top box, when the video terminal information is received from the display module, allowing the detected video terminal, corresponding to the video terminal information, to output video signals, and preventing other video terminals from outputting video signals. The power consumption of the set-top box can be reduced by receiving the information of a connected video terminal from a TV and controlling the other video terminals based upon the information.
