Abstract: A transmission system includes: a master device; and a plurality of slave devices including a first slave device and a second slave device, each of the plurality of slave devices having its own identifier. The master device includes a processor configured to: transmit a control signal of a clock length that the first slave device does not respond to, to the plurality of slave devices at a first timing; and transmit an identifier that identifies the second slave device to the plurality of slave devices at a second timing after the first timing. The second slave device transmits data to the master device when the second slave device receives the control signal and the identifier that identifies the second slave device.

Abstract: An information processing apparatus generating and outputting video signals, a video display apparatus connected to the information processing apparatus and displaying a video based on the video signals received from the information processing apparatus, and a video display system including the information processing apparatus and the video display apparatus, in which a display stop instruction signal is output from the information processing apparatus toward the video display apparatus via a signal line for transmitting, to the information processing apparatus, a connection signal indicating that the video display apparatus is connected to the information processing apparatus to stop and resume the display of the video without delay while preventing a malfunction, during which a pseudo connection signal is generated so that the video display apparatus is not deemed to be removed from the information processing apparatus.

Abstract: A gateway card is connected to an information processor, and receives and transmits data between different networks. The information processor has a normal power mode and a power saving mode. A switching unit connects a memory with the information processor if the information processor is in the normal power mode, or to the gateway card if the normal power mode of the information processor is changed to the power saving mode.

Abstract: A gateway card includes an input-output interface detachably inserted into an insertion section of a personal computer provided with control authority, and a nonvolatile memory that stores control terminal authentication data such as data for a product name for authenticating the personal computer. The card also includes a system data setting section that receives a setting request for system data of the gateway card issued from a terminal and obtains terminal authentication data from the terminal. The system data setting section permits setting of the system data only if there is a match between the control terminal authentication data and the terminal authentication data as a result of comparison.

Abstract: Various home appliances are connected to a gateway card. The gateway card receives a remote control request and remote control data from a remote client. The apparatus to be remote controlled is identified from the remote control request. When remote control request is received, the gateway card receives the changes the power mode of the personal computer from power-saving operation mode to a normal operation mode, sets the remote control data to the apparatus to be remote controlled, notifies the client of completion of the data setting, and changes the power mode of the personal computer from the normal operation mode to the power-saving operation mode.
