A power control system is provided with a plurality of electric appliances and a power control apparatus that controls the operation of the plurality of electric devices. The plurality of electric devices are grouped into one or a plurality of groups, each group containing a plurality of electric devices, and on the basis of state information of the electric devices, the power control apparatus controls the operation of each electric device by group according to a plurality of sets of control contents prepared ahead of time.

Time slice transmission methods transmit data in bursts, thus creating a delay until playback of a service can begin when changing the service and therefore preventing smooth zapping. To solve this problem, a first stream used for burst transmission of packet sets and a second stream for continuously transmitting packets at a speed determined according to the transmission rate required for a particular service are multiplexed and transmitted. The content is reproduced using the continuously transmitted second stream during zapping, and the first stream transmitted in bursts is reproduced after zapping ends.

The zapping stream is transmitted in the same band as the time slice, and therefore the consumption of the transmission band is desirably suppressed to not more than a predetermined amount as far as possible. After restoring the contents from the high-quality contents stream, a specified portion corrected in timing in accordance with the degree of complication of the original image is selectively extracted not at exactly predetermined intervals (not by timing). In this way, the zapping stream is generated with a minimum information amount without deteriorating the quality as far as possible.

A power control system controls electric devices so as to consume a power generated by a self-generated power facility using a natural energy, which is provided with a surplus power detection unit that detects the surplus portion of power generated by the self-generated power facility, and a device control unit that controls the operation of a plurality of electric devices. When the surplus power detection unit detects the surplus power, the device control unit controls one or more of a plurality of electric devices to perform predetermined operations so as to consume the surplus power.

It is possible to prevent an unauthorized read-out from both active tags and passive tags. Antenna emission is turned on and off by using a switch, or attenuated by using a resistor. A part of the antenna may be chipped. With these configurations, it is possible to lower the emission level of the antenna thus preventing an unauthorized read-out of important information from a remote reader.
摘要:
In the invention, zapping streams respectively relating to a plurality of normal service are set in one burst, and the burst is transmitted as a zapping burst. The zapping burst is transmitted in a cycle of one second or less. A PID dedicated to a zapping burst is added to the zapping burst. Association between the zapping burst and the normal service is designated by an IP source address, an IP destination address, or a port number. The transmission performed in this manner make it possible to perform a zapping process without considerably changing an IP encapsulator on a transmission side and an existing receiver.
