Abstract: A sharing device is composed of a distributor and multiple output units. The distributor has multiple input ports to connect different audio sources, such as VCD/DVD players, and has multiple output ports to correspondingly connect to the multiple output units. Each output unit is further connected with a sound output device, e.g. speakers, to broadcast audio signals. When the multiple output units are distributed at different locations, a user in any place is able to select a desired audio source by controlling the output unit and listen to music provided by the selected audio source.

Abstract: The data of the same musical pieces are stored in the same order in each of a plurality of music playback apparatuses. When one music playback apparatus is instructed to finish musical-piece playback, it generates musical-piece playback information indicating the playback order of the musical piece being played at that time, and sends the musical-piece playback information to a mobile telephone. The mobile telephone receives the musical-piece playback information and stores it in its internal memory. When the mobile telephone is moved to a position around another of the music playback apparatuses, the mobile telephone sends the musical-piece playback information to the other music playback apparatus. When the other music playback apparatus is instructed to start musical-piece playback, it selects the musical piece to be played back next, according to the musical-piece playback information sent from the mobile telephone, reads the data of the selected musical piece, and starts playing back the musical piece.

Abstract: To control the audio-recording mode of a video tape recorder used in a communication system, a plurality of pieces of equipment are connected to each other by communication-control buses for carrying out communication among them. Data "71h" set in an OPC (operation-code) field of a command specifying an audio-recording mode of a video tape recorder indicates an audio-recording mode. RM1 to RM4 sub-fields set in an OPR1 (operand) field indicate whether audio recording is to be carried out on Channels 1 to 4 respectively. SF1 to SF4 sub-fields of OPR2 and OPR3 fields indicate the sampling frequencies of Channels 1 to 4 respectively. NA1 to NA4 sub-fields of the OPR2 and OPR3 fields indicate whether one-channel audio recording, two-channel audio recording or 20 bit audio recording is to be carried out on Channels 1 to 4 respectively. Therefore, by transmitting a control signal conveying such a command, other equipment can specify the audio-recording mode of the VTR.

Abstract: Installing a high quality audio source, such as a CD player, in an automobil requires often installation of a radio/tuner of sufficient quality to provide an audio signal corresponding to the quality of the audio source. In leased automobils this presents a problem because of warrenty and return conditions. The problem is solved by using a separate amplifier connected into the wiring between factory installed radio/tuner and loudspeakers and sensing the setting of the radio/tuner control knobs by placing a defined modulated carrier on the antenna input of the radio/tuner. The output of the radio/tuner then provides a signal reflecting the setting of the control knobs. This signal is used to control the amplifier.
