  • Patent number: 9100948
    Abstract: A resource used by a wireless terminal device to communicate with a terminal device in an internal network is appropriately managed. In a communication system 201, an internal network connection device 102 allocates, to a wireless terminal device 150, 151, its own resource for communicating with a terminal device 161 in an internal network 51, transmits data received from the wireless terminal device 150, 151 via the wireless base station device 101, to the terminal device 161, and transmits data received from the terminal device 161, to the wireless terminal device 150, 151 via the wireless base station device 101. The internal network connection device 102 or the wireless base station device 101 determines whether or not the allocation of the resource to the wireless terminal device 150, 151 should be maintained. Upon receiving a determination that the allocation of the resource should not be maintained, the internal network connection device 102 cancels the allocation of the resource.

  • Publication number: 20140092048
    Abstract: The present invention is to allow change of the area in which information as a display target is not displayed in a display according to a detected position by a touch sensor disposed opposed to a touch sensor that is so disposed as to be overlapped on the display. An information processing device (1) includes a touch panel (12) that is so configured as to include a display and a front touch sensor that is so disposed as to be overlapped on the display and detects the position of an object on a detection surface, a back touch sensor (18) that is disposed opposed to the front touch sensor and detects the position of an object on a detection surface, and a control section. The control section identifies, as a prohibited area, one of two areas that each occupy part of the display and are disposed on the left and right sides based on at least one detected position by the back touch sensor (18), and causes information as a display target to be displayed in an area outside the prohibited area in the display.

  • Publication number: 20090010324
    Abstract: A broadcast signal receiving system includes a decoder. The decoder is provided with a first processing system and a second processing system. The first processing system is provided with a first demodulator and a first decoder. The second processing system is provided with a second demodulator and a second decoder. One of the processing systems demodulates and decodes a signal corresponding to a channel selected by a user using a controller and displayed on a display device. The other processing system demodulates and decodes a signal corresponding to a channel predicted by a channel predicting unit to be selected next by the user. When the predicted channel is selected by the user, an output controlling unit switches the source of output of data stream for generating an image to be output to the display device so as to select the processing system that had been processing in the selected channel as a source.
