Disclosed is an optical disk barcode forming method wherein, as information to be barcoded, position information for piracy prevention, which is a form of ID, is coded as a barcode and is recoded by laser trimming on a reflective film in a PCA area of an optical disk. When playing back the thus manufactured optical disk on a reproduction apparatus, the barcode data can be played back using the same optical pickup.

At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

An NFC device according to the present invention includes the following units. An antenna unit receives radio waves from a reader/writer by NFC. A first power source unit generates power from the radio waves. A second power source unit is a drive power source. A power-supply state holding unit holds information indicating a power-supply state of the second power source unit. An NFC unit performs NFC via the antenna unit to transmit the information indicating the power-supply state of the second power source unit. A power source switch unit switches the second power source unit to the first power source unit according to the power-supply state of the second power source unit, in order to supply power to activate at least the NFC unit and the power-supply state holding unit.

An information display device includes: an image display unit that displays an image according to an orientation of a display screen; a terminal posture detection unit that detects a posture of the device using an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor; and a display direction determination unit that determines whether or not the posture of the device changes, and determines the orientation of the display screen. In the case where the display screen is substantially horizontal and the posture of the device changes, the orientation of the display screen is determined so that, when the device moves by a predetermined angle or more with respect to the orientation (reference orientation) of the display screen before the determination of the posture change, a side of the device at the predetermined angle or more from the reference orientation corresponds to the top of the display screen.

An object of the invention is to eliminate a program having a high general preference, and recommend a program customized to a preference of a specific user. A reserved information receiver (230) in a program recommendation server (3) receives reserved information transmitted by a program viewing terminal. A reserved information DB (235) stores the reserved information with respect to each of the users. A community reserved information statistics section (236) defines the users as a first group, based on the received reserved information, and the reserved information stored with respect to each of the users. A total user reserved information statistics section (237) defines the users as a second group including the first group. A recommended program creator (239) generates recommended information customized to the first group, based on an aggregate calculation result of the reserved information of the users belonging to the first group, and an aggregate calculation result of the reserved information of the users belonging to the second group. A recommendation transmitter (240) transmits the recommended information to the program viewing terminal. The program viewing terminal reproduces a program based on the recommended information.

An optical disk for recording stereoscopic videos and high-quality video signals and a system for reproducing the videos and signals from the optical disk are made compatible with the conventional video reproducing system. A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains stereoscopic video or high-quality videos by reproducing both first and second interleaved blocks on the optical disk in which first and second video signals are alternately recorded on the left and right sides by dividing the first and second video signals into frame groups of one GOP or more and a reproducing device which is not used for reproducing the stereoscopic videos and high-quality videos obtains ordinary videos by only reproducing either the first or second interleaved block by jumping tracks.

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.
