In a home bus system control signals and information signals are carried between a transmission station at one location and reception stations at other locations. There are plural signal sources at the transmitting station and plural types of signal formats, such as monaural and stereo or NTSC and HDS. A request signal sent from a receiving station identifies the signal source to be accessed and the signal format capability of a receiver at the receiver station. The request signal is decoded at the transmission station and causes transmission of an information signal from the selected signal source in the identified signal format.

Transmission and reception system

A remote control device having a learning function includes a manipulating section having a plurality of control keys; a first read only memory having storage portions which correspond to the keys and store informations for remote control signals in advance; a reception section for receiving a remote control signal; a mode changeover section for shifting the operation mode of the device between a reception mode and a transmission mode; an erasable second memory which has storage portions corresponding to the control keys of the manipulating section; a writing section for writing the information of the remote control signal received by the reception section into the storage portion of the second memory corresponding to the manipulated control key of the manipulating section when the operation mode is shifted to the reception mode; a reading section for reading the information stored in the storage portions of the first and second memory, which correspond to the manipulated control key of the manipulating section, in response to the manipulation of the key when the operation mode is shifted to the transmission mode; and a transmission section for transmitting the remote control signals formed from the information read by the reading section.

Remote control device with learning function

Carrier frequencies different in frequency from each other are modulated with broadcast signals different from each other, and the thus modulated signals are transmitted through a single transmission line and are suited for reception and demodulation. A programming circuit allows programming of a plurality of different programs, with each program being able to be programmed to activate any selected receivers of a plurality of receivers, and to tune each of the selected receivers to any selected carrier frequency. The different programs are stored in a memory, and each of the receivers is connected to a speaker. A selection circuit allows a user to select any one of the different programs to output the broadcast signals at selected frequencies from selected speakers.

Programmable signal reception system

A MIDI apparatus and a MIDI system wherein an operation ON signal for starting operation to a MIDI instrument and an operation OFF signal for stopping the operation are obtained and supplied to the MIDI instrument in response to a MIDI format signal included in a subcode signal generated during play of a record medium play apparatus. If the play state of the record medium play apparatus becomes discontinuous, such as a pause after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal is obtained, the operation OFF signal is forcedly supplied to the MIDI instrument. Thereby such the sound of the MIDI instrument is stopped when there is a discontinuous play state after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal would ordinarily be supplied.

Midi control apparatus and midi system

A remote control signal processing device includes a signal receiving unit that receives a remote control signal from a remote control apparatus, demodulating means that generates and outputs signal data corresponding to the format and code of the received remote control signal, a memory unit for storing the signal data of the received remote control signal and having storage areas associated with control signals, operating keys that are associated with the storage areas and select the storage areas, a select switch selectively sets a recording mode or an operating mode, and a control unit which, when the select switch is set into the recording mode, writes the signal data of the received remote control signal into one of the storage areas associated with a depressed one of the operating keys and which, when the select switch is set into the operating mode, sequentially reads out the loaded signal data from the memory unit for comparison with the signal data of the received remote control signal, the control unit supplying a machine with control signals associated with the storage areas where the signal data found to match the received signal data has been written.

Remote control signal processing device

A learning remote control device includes: a receiving section for receiving and demodulating a remote control signal from a remote control device; a memory for storing data obtained by the receiving section through demodulation; control keys each corresponding to a prescribed storage region of the memory; a transmitting section for reproducing the remote control signal on the basis of the data read from the memory and for transmitting the reproduced remote control signal; a switch for shifting the operation mode of the learning remote control device to reception mode or transmission mode; and a control section for writing the data from the receiving section into the storage region corresponding to one of the control keys in case that the operation mode is shifted to the reception mode by the switch, and for reading the data from the storage region corresponding to an operated one of the control keys to send out to the transmitting section in case that the operation mode is shifted to the transmission mode by the switch.
