Abstract
A display device includes: a monitor and receiving set having a video signal receiving section, a display section, an image quality control section, a first control signal transceiver, and a first control section; and a control and transmission set having a television broadcast receiving section, a video signal input section, a video signal transmitting section, a second control signal transceiver, a key input section, and a second control section. The Power consumption of a first radio transmission path formed by the video signal transmitting section and the video signal receiving section is larger than that of a second radio transmission path formed by the first and second control signal transceivers. A control signal for a user interface is communicated by the first and second control signal transceivers. Only the second radio transmission path of the first and second radio transmission paths is communicable in a standby state.
