`
`from the invention. Accordingly, the drawings and descrip-
`tion are to be regarded as illustrative in nature, and not
`restrictive.
`
`[0020] FIG. 1 shows a block diagram of an online music-
`data-providing system via a car kit according to a preferred
`embodiment of the present invention.
`
`[0021] As shown, the online music-data-providing system
`via a car kit comprises a music-data-providing server 10; a
`mobile communication system 20; a mobile station 30; and
`a car kit 40.
`
`[0022] The music-data—providing server 10 stores a plu-
`rality of music data, and transmits stored music data to the
`mobile station through the Internet 50 according to a down-
`load request by a member user that is a mobile station user.
`
`[0023] The user accesses the music—data—providing server
`10 through the mobile station 30. In this instance, the mobile
`station 30 is wirelessly connected to the mobile communi-
`cation system 20, and the mobile communication system 20
`is connected to the music-data-providing server 10 through
`the Internet 50.
`
`[0024] The car kit 40 is installed in the user’s car 60, and
`is connected to the mobile station 30 that is temporarily
`positioned in the car 60 through a short range radio link by
`the Bluetooth protocol.
`
`[0025] FIG. 2 shows a detailed block diagram of the
`mobile station 30 and the car kit 40 in the online music-
`data-providing system of FIG. 1.
`
`[0026] As shown, the mobile station 30 comprises a wire-
`less transmitting and receiving unit 32; a user interface 34;
`a data processing and controlling unit 36; and a Bluetooth
`communication unit 38.
`
`[0027] The wireless transmitting and receiving unit 32
`enables the mobile station 30 to process data, and enables
`radio links between the data processing and controlling unit
`36 and the mobile communication system 20.
`
`[0028] The user interface 34 connects the user to the data
`processing and controlling unit 36, and it comprises an LCD
`and a key input device.
`
`[0029] The Bluetooth communication unit 38 enables
`short range radio links by the Bluetooth protocol between
`the data processing and controlling unit 36 and the car kit 40.
`
`[0030] The data processing and controlling unit 36 pro-
`cesses the data input by the mobile communication system
`20 through the wireless transmitting and receiving unit 32 to
`output them to the user interface 34 or output them to the car
`kit 40 through the Bluetooth communication unit 38, pro-
`cesses the data input from the car kit 40 through the user
`interface 34 or the Bluetooth communication unit 38 to
`wirelessly transmit them to the mobile communication sys-
`tem 20 through the wireless transmitting and receiving unit
`32, thereby controlling the whole operation of the mobile
`station 30.
`
`In this instance, the Bluetooth communication unit
`[0031]
`38 follows technology specifications, standardized by the
`Bluetooth SIG (Special Interest—Group), a technique stan—
`dardizing consortium, [or short range radio links (2.4 GHz
`ISM Open Band) between portable devices such as a mobile
`
`station and a mobile computer and other peripheral devices
`with small size, low cost, and low power consumption.
`
`[0032] The car kit 40 comprises a Bluetooth communica-
`tion unit 400;
`a voice coder 410;
`a controller 420;
`a
`decompressor 430; an audio output unit 440; and speakers
`450 and 460.
`
`[0033] The Bluetooth communication unit 400 enables
`short range radio links by the Bluetooth protocol between
`the mobile station 30 and the controller 420 of the car kit 40.
`That is, the Bluetooth communication unit 400 forms a call
`path by the Bluetooth protocol to the Bluetooth communi-
`cation unit 38 of the mobile station 30.
`
`[0034] The Bluetooth call path includes an asynchronous
`call path for transmitting data, and a synchronous call path
`for transmitting voice signals. The voice coder 410 com-
`prises a coder 412 for converting voice signals input through
`the microphone 416 into digital signals, the voice signals
`being used for browsing contents such as telephone calls on
`a voice basis; and an echo canceller 414 for canceling the
`speaker sound input to the microphone.
`
`[0035] The decompressor 430 decrypts and decompresses
`the music data encrypted and compressed by the music—data—
`providing server 10.
`
`[0036] The music-data-providing server 10 may transmit
`streaming music data and non—streaming general music data
`according to the user’s selection.
`
`[0037] The streaming music data may be reproduced when
`the corresponding data are not completely received, and the
`general music—data may be reproduced when they are com—
`pletely received.
`
`[0038] Therefore, the decompressor 430 decompresses the
`data dilferently according to data types input by the music—
`data-providing server 10, that is, depending on whether it is
`streaming music data or general music data.
`
`[0039] The decompressor 430 comprises a decryptor 432
`for decompressing the streaming music data; a decoder 434
`for decoding the general music data; and a decryptor 436 for
`decompressing the data decoded by the decoder 434.
`[0040] The controller 420 controls the Bluetooth commu-
`nication unit 400 to form a call path to the Bluetooth
`communication unit 38 of the mobile station 30, and pro-
`cesses the data input by the mobile station 30 to output them
`to the decompressor 430,
`thereby controlling the whole
`operation of the car kit 40.
`
`[0041] The audio output unit 440 outputs the music data
`output by the decompressor 430 so that the user may listen
`to them through the two speakers 450 and 460. The audio
`output unit 440 comprises a D/A converter 442 for convert-
`ing the music data output by the decompressor 430 into
`analog signals; and an amplifier 444 for amplifying the
`analog signals output by the D/A converter 442 to output to
`the speakers 450 and 460.
`
`[0042] The controller 420 comprises a memory for storing
`music data and other data transmitted by the mobile station
`30.
`
`[0043] Referring to FIGS. 3(a) and 3(b), an operation of
`the online music providing system via a car kit according to
`the preferred embodiment of the present invention will now
`be described.

`
`It is assumed that the user of the mobile station 30
`[0044]
`is previously registered to the music—data—providing server
`10 through the car kit 40. An operation to enter a server or
`a site that provides predetermined services as a member is
`obvious to a skilled person
`
`[0045] When the user turns on the car kit 40 installed in
`the car 60 in step S10, the car kit 40 performs its own
`initialization process in step 520.
`
`In this instance, the initialization process enables
`[0046]
`the controller 420 of the car kit 40 to check states of
`respective components in the car kit 40, and the controller
`420 provides communication instructions to the Bluetooth
`communication unit 400 and the mobile station 30 after the
`initialization process in step S30.
`
`[0047] The car kit 40 enters a standby state of a response
`signal from the mobile station 30 in step S40.
`
`[0048] The mobile terminal 30 receives the communica—
`tion instruction from the Bluetooth communication unit 400
`of the car kit 40 in step 850, and transmits a response signal
`to the communication instruction to the car kit 40 in step
`S60.
`
`In further detail, when receiving the communica—
`[0049]
`tion instruction by the Bluetooth communication protocol
`from the Bluetooth communication unit 400 of the car kit 40,
`the Bluetooth communication unit 38 of the mobile station
`30 transmits this fact to the data processing and controlling
`unit 36, and the data processing and controlling unit 36
`controls the Bluetooth communication unit 38 to transmit a
`response to the communication instruction transmitted by
`the car kit 40 to the Bluetooth communication unit 400 of the
`car kit 40.
`
`[0050] The Bluetooth communication unit 400 of the car
`kit 40 receives the response signal from the Bluetooth
`communication unit 38 of the mobile station 30, transmits
`the same to the controller 420, and the controller 420 checks
`synchronous/asynchronous link states to the mobile station
`30 in step S70, and when the synchronous/asynchronous
`link states are normal, it stands by until the music data are
`downloaded from the mobile station 30 in step S80.
`
`[0051] The user requests wireless Internet access from the
`music—data—providing server 10 through the user’s mobile
`station 30 in step 890, and the music-data-providing server
`10 determines whether the user is registered regarding the
`access request by the mobile station 30, and issues an access
`allowance in step $100.
`
`[0052] When receiving the access allowance from the
`music-data-providing server 10, the user uses the mobile
`station 30 to select each desired music file or a plurality of
`music files in step $110.
`
`to download the
`[0053] The user transmits a request
`selected music file data to the music—data—providing server
`10 in step $120, and concurrently transmits an instruction to
`the car kit 40 to notify of a start of downloading the music
`data in step $130.
`
`[0054] The music-data-providing server 10 wirelessly
`transmits the selected music file data to the user’s mobile
`station 30 according to the corresponding downloading
`request through the mobile communication system 20 con-
`nected to the Internet 50 in step $140, and the mobile station
`
`30 receives the music file data from the music-data-provid-
`ing server 10 and transmits them to the car kit 40 in step
`$150.
`
`[0055] When receiving the instruction to notify of the start
`of downloading data from the mobile station in step $160,
`the controller 420 of the car kit 40 stands by so as to receive
`the music data from the mobile station 30, and when the
`mobile station 30 transmits the music data, the controller
`420 receives the music data, stores them in the memory 470
`in step $170, and checks the compression format of the
`music data in step $180.
`
`[0056] When the compression format of the received
`music data is not the streaming type but the general type in
`step $190, the controller receives the total music data and
`stores the same in the memory 470 in step $200.
`
`[0057] The decoder 434 of the decompressor 430 decodes
`the general music data stored in the memory 470 in step
`S210, and the decryptor 436 decompresses the decoded
`music data and outputs them to the audio output unit 440 in
`step $220.
`
`[0058] When the compression format of the received
`music data in the previous step S190 is a streaming type, the
`controller 420 receives the music data and transmits them to
`the decompressor 430, and the decryptor 432 of the decom-
`pressor 430 decompresses the transmitted music data and
`outputs them to the audio output unit 440 in step $230.
`
`[0059] The D/A converter 442 of the audio output unit 440
`converts the digital music data output by the decompressor
`430 into analog signals of the audible frequency band, and
`outputs them in step $240, and the amplifier 444 amplifies
`the analog signals in step S250, and outputs them so that the
`user may listen to the same from the two speakers 450 and
`460 in step $260.
`
`[0060] When a third person calls the user’s mobile station
`30 while the user is listening to music selected through the
`car kit 40 after the above-described process, in other words,
`when an external voice call access is requested, the data
`processing and controlling unit 36 of the mobile station 30
`notifies the controller 420 of the car kit 40 of the external
`voice call access request, the controller 420 temporarily or
`completely stops the present music reproducing operation,
`and when the user uses the user interface 34 to connect to the
`external voice call access,
`the car kit 40 operates as a
`hands-free function of the mobile station 30.
`
`the music being re produced is
`In this instance,
`[0061]
`stopped when the user presses a call button provided to the
`user interface 34 of the mobile station 30 or presses the same
`provided to the car kit 40. The technical scope of the present
`invention is not restricted to this, and further various meth-
`ods may be implemented.
`
`[0062] When the user presses the call button (not illus-
`trated) installed in the car kit 40, this fact is transmitted to
`the controller 420, and the controller 420 performs a process
`depending on the operation status of the car kit 40. For
`example, when the user receives a telephone call request
`while reproducing the music data, and presses a call button,
`the music data are stopped temporarily or completely. In the

`
`[0063] When the reproduced music is stopped, an external
`telephone call connection is performed, and the user speaks
`through the microphone 416 of the voice coder 410,
`the
`coder 412 converts the user’s voice into corresponding
`digital signals and outputs them to the controller 420, and
`the controller 420 transmits the converted voice signals to
`the mobile station 30 to be transmitted to the third person.
`In this instance, the echo canceller 414 cancels the speaker
`sound input through the microphone 416.
`
`[0064] Also, when the third person’s voice data are trans—
`mitted to the car kit 40 through the mobile station 30, the
`controller 420 outputs the voice data through the speakers
`450 and 460 so that the user may listen to the third person’s
`v01ce.
`
`[0065] When someone calls the user while the user is
`reproducing music data,
`the user may answer the phone
`according to the above-noted operation, and the temporarily
`paused music data may be reproduced according to the
`user’s predetermined action, such as pressing the call button
`after the telephone call is finished.

`a case when an external call
`In the above,
`[0066]
`provided While music data are reproduced is described, and
`further, when someone calls the user while the user is
`receiving desired music file data from the music-data-
`providing server 10, the user may completely or temporarily
`stop receiving the music file data as described above, answer
`the phone, and start receiving the music file data that was
`completely or temporarily stopped after the call is finished.
`
`[0067] According to the present invention, since the music
`files distributed by the music-data-providing server 10 are
`encoded, they may not be transmitted or reproduced to other
`devices except the car kit 40.
`
`[0068] Further, the present invention may provide various
`categories of contents in addition to the online music data
`distribution service through the car kit 40.
