  • Patent number: 8391502
    Abstract: In an audiovisual system in which a source device and a television are connected via an AV amplifier, even when the AV amplifier is placed in a “Power Supply Standby State”, video/audio signals outputted from the source device can be viewed/listened to on the television without changing the wiring connections between the devices. An AV amplifier (100) is provided with a data storing means (106) used for indicating a signal reproduction ability to a source device (200). During a “Power Supply Standby State” of the AV amplifier (100), the content of data that is saved in the data storing means (106) and indicates an audio signal reproduction ability is rewritten into data that indicates not the reproduction ability of the AV amplifier (100), but the signal reproduction ability of a television (300), thereby producing a state that is equivalent to a state in which the source device (200) and the television (300) are directly connected.

  • Patent number: 8175298
    Abstract: In an audio output system including a TV, an AV amplifier, a DVD player, and the like, a simple control program decides an audio output mode setting, i.e., whether to output audio from a built-in speaker of the TV or output audio from an external speaker connected to the AV amplifier by linking operations of the respective devices. A control unit of a DVD player transmits a request signal concerning the audio output mode to a control unit of a TV. According to a request from the DVD player, the control unit of the TV instructs a control unit of an AV amplifier to be set to a mode for outputting audio from an external speaker connected to the AV amplifier or a mode for not outputting audio and sets a built-in speaker of the TV to a state opposite to the state of the external speaker.

  • Patent number: 8131128
    Abstract: In an audiovisual system in which a TV, an AV amplifier, a DVD player and the like are combined, another device constituting the system is automatically set to an optimal operation state according to the content recorded on an optical disc. A reproduction content judging unit 406 of a DVD player 400 judges the type (a video signal and an audio signal) and the format of signals included in content that has been read from the optical disc 401. According to the results of judging by the reproduction content judging unit 406, a control unit 403 of the DVD player 400 sends an instruction signal related to the power supply state and an instruction signal related to output of at least one of video and audio to a control unit 105 of a TV 100 and a control unit 203 of an AV amplifier 200.

  • Publication number: 20090046210
    Abstract: An audiovisual system is provided in which the operability of selection by a user between internal speakers of a TV and external speakers connected to an audio amplifier has been improved, thus reducing the burdensomeness of operation. When an audio amplifier (100A) is powered on, a control part (106A) of the audio amplifier (100A) judges that use of external speakers (105) connected to the audio amplifier (100A) has been selected, and transmits a control signal for putting internal speakers (205) of a TV (200A) in a muted state to a control part (206A) of the TV (200A) via a communication means (300). Conversely, when the audio amplifier (100A) is powered off, the control part (106A) judges that use of the internal speakers (205) of the TV (200A) has been selected, and transmits a control signal for canceling the muted state of the internal speakers (205) to the control part (206A) of the TV (200A) via the communication means (300).

  • Patent number: 4821175
    Abstract: A database processing device executes concurrent processing in accessing a database through a plurality of independent terminal units. The database processing device, upon updating data stored in a record after reading out the data stored in the record in the database and correcting or altering the data through a specific terminal, confirms whether or not the data stored in the record has been updated by terminals, and executes updating only when the data has not been updated. The data stored in the record includes update control information for confirming whether or not the data has been updated by other terminals.
