`
`coder 410; a controller 420; a decompressor 430; an audiooutput unit 440;
`
`and speakers 450 and 460.
`
`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 communication
`
`unit 88 of the mobile station 30.
`
`The Bluetooth call path includes an asynchronous call path for
`
`transmitting data, and a synchronous call path for transmitting voice signals.
`
`10
`
`The voice coder 410 comprises 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.
`
`The decompressor 430 decrypts and decompresses the music data
`
`encrypted and compressed by the music-data-providing server 10.
`
`The music—data—providing server 10 may transmit streaming music
`
`data and non-streaming general music data according to the user’s selection.
`
`The
`
`streaming music data may
`
`be
`
`reproduced when
`
`the
`
`20‘ W "
`
`corresponding data are not completely received, and'the general musicdata
`
`may be reproduced when they are completely received.
`
`Therefore, the decompressor 430 decompresses the data differently
`
`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.

`
`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
`

`
`U1
`
`The controller 420 controls the Bluetooth communication unit 400 to
`
`form a call path to the Bluetooth communication unit 38 of the mobile station
`
`30, and processes 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.
`
`.
`
`10
`
`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 converting the music data output by the decompressor 430 into
`
`analog signals; and an amplifier 444 for amplifying the analog signals output
`
`15
`
`by the D/A converter 442 to output to the speakers 450 and 460.
`
`The controller 420 comprises a memory for storing music data and
`
`other data transmitted by the mobile station 30.
`
`Referring to Fle. 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 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.

`
`When the user turns on the car kit 40 installed in the car 60 in step
`
`810, the car kit 40 performs its own initialization process in step $20.
`
`In this instance, the initialization process enables the controller 420 of
`
`the car kit 40 to check'states of respective components in the car kit 40, and
`
`5
`
`the controller 420 provides communication instructions to the Bluetooth
`
`communication unit 400 and the mobile station 30 after the initialization
`
`process in step 830.
`
`The car kit 40 enters a standby state of a response signal from the
`
`mobile station 30 in step 840.
`
`10
`
`The mobile terminal 30 receives the communication 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 860.
`In further detail, when receiving the communication instruction by the
`
`15
`
`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:
`
`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 880.
`
`The user requests wireless lnternet access from the music-data-
`
`U!
`
`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 8100.
`
`When receiving the access allowance from the music-data—providing
`
`10
`
`server 10, the user uses the mobile station 30 to select each desired music
`
`file or a plurality of music files in step 81 10.
`
`The user transmits a request to download the selected music file data
`
`to the music—data—providing server 10 in step 8120, and concurrently
`
`transmits an instruction to the car kit 40 to notify of a start of downloading the
`
`15
`
`music data in step 8130.
`
`The music—data-providing server to 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
`
`connected to the lnternet 50 in step 8140, and the mobile station 30 receives
`
`“'the music file data from the music—data-providing' server 10 and transmits
`
`them to the car kit 40 in step 81 50.
`
`When receiving the instruction to notify of the start of downloading
`
`data from the mobile station in step 8160, 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 8170, and
`
`checks the compression format of the music data in step $180.
`
`When the compression format of the received music data is not the
`
`streaming type but the general type in step 8190, the controller receives the
`
`total music data and stores the same in the memory 470 in step 8200.
`
`The decoder 434 of the decompressor 430 decodes the general
`
`music data stored in the memory 470 in step 8210, and the decryptor 436
`
`decompresses the decoded music data and outputs them to the audio output
`
`10
`
`unit 440 in step 8220.
`
`When the compression format of the received music data in the
`
`previous step 8190 is a streaming type, the controller 420 receives the music
`
`data and transmits them to the decompressor 430, and the decryptor 432 of
`
`the decompressor 430 decompresses the transmitted music data and outputs
`
`them to the audio output unit 440 in step 8230.
`
`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 S240, and the amplifier
`
`444 amplifies the analog signals in step S250, and outputs them so that the
`
`20
`
`user may listen to the same from the two speakers 450 and 460 in step 8260.
`
`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‘BO.
`
`In this instance, the music being reproduced is 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 methods
`
`10
`
`may be implemented.
`
`When the user presses the call button (not illustrated) 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
`
`15
`
`the music data, and presses a call button,
`
`the music data are stopped
`
`temporarily or completely. in the like manner, when the user presses the call
`
`button again after the telephone call is finished, the stopped music data may
`
`be reproduced again.
`
`When the reproduced music is stopped, an external telephone call
`
`20'
`
`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
`
`12
`

`Samsung Ex. 1306 p. 13
`
`

`

`W0 02/096137
`
`PCT/KR01/01824
`
`cancels the speaker sound input through the microphone 416.
`
`Also, when the third person’s voice data are transmitted 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
`
`U1
`
`person’s voice.
`
`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
`
`10
`
`telephone call is finished.
`
`In the above, a case when an external call is 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
`
`15
`
`the music file data that was completely or temporarily stopped after the call is
`
`finished.
`
`According to the present invention, since the music files distributed
`
`by the music—data—providing server 10 are encoded,
`
`they may not be
`
`20 ‘
`
`transmitted or reproduced to other devices except" the car kit 40.
`
`"
`
`'
`
`Further,
`
`the present
`
`invention may provide various categories of
`
`contents in addition to the online music data distribution service through the
`
`car kit 40.
