Abstract
An automotive audio system includes a first unit for acquiring a sound signal to be reproduced, a second unit for controlling the first unit by means of a control signal and also reproducing the supplied sound signal, and a bus for establishing communication between the first unit and the second unit. The control signal and the sound signal are transferred in digital format between the first unit and the second unit via the bus.
Claims20
An automotive audio system comprising:
- a first unit for acquiring a sound signal to be reproduced;
- a second unit for controlling said first unit by a control signal and also reproducing the supplied sound signal;
- and
- a bus for establishing communication between said first unit and said second unit, wherein the control signal and the sound signal in digital format are transferred between said first unit and said second unit via said bus.
An automotive audio system comprising:
- a first unit for acquiring a sound signal to be reproduced;
- a second unit for controlling said first unit by a control signal and also reproducing the supplied sound signal;
- and
- a bus for establishing communication between said first unit and said second unit, wherein the control signal and the sound signal in digital format are transferred between said first unit and said second unit via said bus,
- wherein said first unit comprises:
- a playback means for reading a sound signal from a recording medium, and
- said bus converter means comprises:
- a command resolving means for sending a command for reading predetermined volume of sound signal from a designated address on the recording medium to said playback means at predetermined time intervals in accordance with the contents of the supplied control signal.
A method of controlling an automotive audio system comprising:
- acquiring a sound signal to be reproduced by a first unit;
- controlling said first unit by a control signal and also reproducing the supplied sound signal by a second unit;
- and
- establishing communication between said first unit and said second unit by a bus,
- wherein the control signal and the sound signal in digital format are transferred between said first unit and said second unit via said bus.
