Abstract
A head unit outputs a control bus command in response to an input operation by a user. A conversion unit converts the control bus command into a USB data frame and outputs The USB data frame to a notebook personal computer. Based on the USB data frame, and notebook personal computer reads music data stored in a hard disk drive, and outputs the music data to the head unit via the conversion unit. If the music data is compressed, the music data is decoded at the notebook personal computer. Thus, a dedicated decoding LSI need not be provided in the head unit.
Claims15
A data playing system comprising:
- operation means for outputting a first control signal corresponding to an input operation by a user;
- conversion means for converting the first control signal output from the operation means into a second control signal compliant with an interface standard that is different from an interface standard for the first control signal, and for outputting the second control signal;
- data storage means for reading and outputting data stored therein, based on the second control signal input from the conversion means;
- and
- playing means for playing the data output from the data storage means.
A data playing system comprising:
- a computer apparatus for reading and outputting recorded data;
- and
- a playing apparatus connected to the computer apparatus;
- wherein the playing apparatus comprises an operation unit that allows operation by a user, the playing apparatus outputs a control signal corresponding to an input operation at the operation unit to the computer apparatus, the computer apparatus reads and outputs the recorded data based on the control signal input to the computer apparatus, the computer apparatus transmits the recorded data to the playing apparatus, and the playing apparatus plays the recorded data output from the computer apparatus.
A data playing system comprising:
- a computer apparatus that allows playing data to be stored therein;
- a playing apparatus for playing the playing data output from the computer apparatus;
- a first bus connected to the computer apparatus, for allowing input and output of data to and from the computer apparatus;
- a second bus for outputting a control signal from the playing apparatus based on an input operation at the playing apparatus;
- a third bus for inputting the playing data to the playing apparatus;
- a control signal converter connected between the first bus and the second bus, for converting the control signal output via the second bus into a signal that can be read by the computer apparatus and for transmitting the signal to the first bus;
- and
- a playing data converter connected between the first bus and the third bus, for converting the playing data output via the first bus into data that can be read by the playing apparatus, and for transmitting the data to the third bus.
A transmitting and receiving apparatus for transmitting and receiving data between a computer and a playing apparatus, comprising:
- a playing-apparatus-side receiving unit for receiving a data command output from the playing apparatus;
- a first converter for converting the data command received by the playing-apparatus-side receiving unit into a data frame that can be read by the computer;
- and
- a computer-side transmitting unit for transmitting the data frame obtained by the conversion by the first converter to the computer.
A bus conversion unit comprising:
- a hub that can be connected to a first bus compliant with a predetermined standard;
- a digital-to-analog converter connected to the hub, for converting a digital signal input from the first bus to the hub into an analog signal;
- and
- a bus converter that is connected to the hub and that can be connected to a second bus compliant with a standard that is different from the standard for the first bus;
- wherein the bus converter converts a signal in a predetermined data frame format input from the first bus to the hub into a command in a predetermined format, and converts a signal input from the second bus as a command in the predetermined format into a signal in the predetermined data frame format, outputting the signal in the predetermined data frame format to the first bus.
