Abstract:
A first communication unit (11) transmits, to an electrical home appliance (2), request information that requests electrical home appliance specifying information for specifying the electrical home appliance (2) after an approach instructing screen is displayed on a display unit (13), and receives response information including at least the electrical home appliance specifying information from the electrical home appliance (2) after the first communication unit (11) and the electrical home appliance (2) have approached each other within a communicable range, and a display control unit (141) switches a display screen to a menu screen that is unique to the electrical home appliance (2) on the basis of the response information received by the first communication unit (11).
Abstract:
The communication device can easily serve as an extended user interface such as a remote controller of a target apparatus without causing any complicated operations to a user. The communication device includes the following units. An apparatus information obtainment unit (203) obtains apparatus information from an apparatus. A position information obtainment unit (206) obtains position information of the communication device (102). An operation information obtainment unit (212) obtains operation information based on the apparatus information. A storage unit (213) stores the position information as apparatus position information indicating as a position of the apparatus, in association with the operation information. A direction sensor unit (207) detects direction of the communication device (102). A directional space calculation unit (208) calculates a directional space of the communication device (102). A selection unit (209a) specifies the apparatus existing in the directional space based on the apparatus position information and selects the operation information associated with the specified apparatus. An operation information transmission unit (215) transmits, based on the selected operation information, a control signal to the specified apparatus so as to allow the communication device to operate the apparatus.

Abstract:
Sub-information necessary for reproduction of main information is recorded on an optical disc without deterioration of reading accuracy of the main information, so that illegal reproduction is prevented. After a concave and convex mark (MK) synchronizing with integer times a channel bit length is formed on optical disc (1) in accordance with modulated main information, a reflective film (IL) is formed on the concave and convex mark (MK). After the optical disc (1) is molded, a continuous or intermittent laser light, which has an interval that is longer than the longest mark in the concave and convex mark (MK) and is synchronous with integer times the channel bit length, is irradiated to the reflective film (IL) which, in turn, changes its chemical characteristic to form a recordable mark, so that the sub-information necessary for reproduction of the main information is recorded in a superimposition manner.
