The present invention provides a control apparatus and the like capable of performing exclusive control in a network without adding a new configuration to an existing apparatus to be controlled and, even in the case where the apparatus to be controlled or the like drops from the network, capable of maintaining and continuing the original exclusive control state. In a bus system S in which an apparatus C to be controlled and a control apparatus CC are exclusively associated with each other and the operation of one apparatus C to be controlled is controlled by one control apparatus CC, exclusive control information indicating correspondence between operation of each of the apparatuses C to be controlled and a control apparatus CC which controls the operation is stored similarly in all of the control apparatuses CC with respect to each of the apparatuses to be controlled. The operation in any of the apparatuses C to be controlled is controlled by the control apparatus CC on the basis of the stored exclusive control information.

Control apparatus and control method, network system, program for control apparatus, and information recording medium

A relay device and the like are provided which are capable of easily transmitting/receiving information among information processors connected on buses whose information transmission standards are different from each other. A bridge Bfor connecting buses BSand BSwhose information transmission standards are different from each other includes: an operation unit () for performing an operation of instructing an operation of an apparatus connected to any of the buses BS; a message generatorfor generating a control message corresponding to the instructed operation; and a packet transmitter/receiver () for transmitting the generated control message to a target apparatus via the bus BS to which the target apparatus is connected.

Relay device, relay method, and information recording medium

A method for reserving recording and viewing a broadcast program on a display screen includes the steps of extracting a broadcast program timetable; simultaneously displaying the broadcast program timetable and a viewing reservation timetable; waiting for a selection input to select a broadcast program on the display screen; waiting for an allocation input to allocate a selected program into the viewing reservation timetable; and generating recording instruction to instruct recording of the selected program and reproduction reservation instruction to instruct reproduction of the selected program at a time corresponding to a position at which the selected program is allocated in the viewing reservation timetable.

Program recording and viewing reservation system and method thereof

On an information recording medium ( ), digital information is multi-level-recorded by changing a shape of an information pit in correspondence with the digital information by multiple steps. An information reproducing apparatus (S) for reproducing the digital information from the information recording medium is provided with: a detection signal generating device ( ) for generating an analog detection signal corresponding to the information pit; a sampling device ( ) for sampling the generated analog detection signal at a sampling cycle corresponding to a cycle, at which the information pit is formed on the information recording medium, to thereby generate a sampling detection signal; an extracting device ( ) for extracting a level fluctuating component, which is included in the analog detection signal, out of the generated sampling detection signal; a first subtraction signal generating device ( ) for subtracting the extracted level fluctuating component from the generated sampling detection signal, to thereby generate a first subtraction signal; and a reproducing device ( ) for reproducing the digital information on the basis of the generated first subtraction signal.
