Abstract: According to one embodiment, a display control device includes a receiving module, a transmission module, a reception module, and a display processor. The receiving module is configured to receive an operation on a first cursor represented on screen information received from an information processing device via a network when the screen information is displayed. The transmission module is configured to transmit positional information on a second cursor making the first cursor move in accordance with the operation received by the receiving module. The reception module is configured to receive screen information after the positional information on the second cursor is transmitted from the information processing device.

Abstract: According to one embodiment, a communication controller includes: an output module; a transmitter; and a receiver. The output module is configured to control output of image information to a display. The transmitter is configured to transmit the image information to a first communication device by unicast. The receiver configured to receive a transmission request of the image information from a second communication device. If the receiver receives the transmission request from the second communication device, the transmitter stops transmission of the image information to the first communication device by unicast, and transmits the image information to the first communication device and the second communication device by multicast.
