1． Configuration of Embodiment Next, the configuration of a music content distribution system according to an embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 1 denotes a mobile phone held by a general user. In the inside, reference numeral 2 denotes a CPU, which controls each part in the mobile phone 1 via the bus 12 based on a program stored in the flash memory 4. In addition to such programs, the flash memory 4 stores MIDI data, PCM data, and the like, and these are used for synthesizing automatically reproduced sounds such as ringtones and alarm sounds. A volatile memory RAM 6 is used as a work memory for the CPU 2. Reference numeral 8 denotes a display that displays various information to the user. Reference numeral 10 denotes a keyboard, which includes a numeric keypad and function keys.

  Reference numeral 16 denotes an RFID communication unit which transmits a radio wave S1 having a constant frequency and a constant amplitude via the antenna 14, receives a radio wave S2 having a frequency obtained by multiplying the radio wave S1, and demodulates the radio wave S2. Receive data. A telephone communication unit 18 modulates a voice signal input from the microphone 20 or a data signal supplied via the bus 12 and transmits the modulated signal to the cellular phone network via the antenna 24 and receives the signal from the cellular phone network. The audio and data signals are demodulated, the demodulated audio signals are generated via the speaker 22, and the demodulated data signals are output via the bus 12. A sound source unit 26 generates a musical sound signal based on MIDI data or PCM data supplied from the CPU 2 and emits the sound through the speaker 28.

  Next, the RFID tag 30 is a label-like RFID tag attached to a medium containing music content such as a CD or a package thereof. Inside, 32 is an antenna that receives the radio wave S1. Reference numeral 34 denotes a power supply unit that rectifies the received radio wave S <b> 1 and generates a DC voltage applied to each unit in the RFID tag 30. Reference numeral 38 denotes a CPU that controls each part in the RFID tag 30 via the bus 44 based on a program stored in the ROM 40. A RAM 42 is used as a work memory for the CPU 38. A communication unit 36 multiplies the received radio wave S1 to generate a carrier wave of the radio wave S2, modulates the carrier wave with transmission data supplied from the CPU 38, and outputs the modulated signal as the radio wave S2 via the antenna 32. To do.

In addition to the program, the ROM 40 stores the following data.
(1) Audition data: The audition data is performance information (MIDI, SMAF, etc.) or PCM data of a part of a phrase (for example, a chorus part) of the music related to the music content.
(2) Accompanying data: The accompanying data indicates the identification number of the trial data, and whether or not the user is permitted to use the trial data as an automatic reproduction sound (ringing tone, alarm sound, etc.) of the mobile phone 1. Information such as an automatic reproduction permission flag and a price when the use of the audition data as an automatic reproduction sound is charged is included.
(3) End code: The end code is data transmitted to indicate that the transmission of the trial listening data and the accompanying data is completed. Further, the end code includes the sample data and the checksum value of the accompanying data flag.

2． Next, the operation of the present invention will be described.
First, in the RFID tag 30, when the intensity of the received radio wave S1 is sufficiently increased, a predetermined voltage is output from the power supply unit 34, and the operation of each unit such as the CPU 38 becomes possible. Then, the CPU 38 executes a transmission routine shown in FIG. In the figure, when the process proceeds to step SP52, the audition data stored in the ROM 40 is transmitted via the communication unit 36. Similarly, accompanying data is transmitted in step SP54, and a predetermined end code is transmitted in step SP56. Thereafter, as long as the sufficiently strong radio wave S1 continues to be supplied, the steps SP52 to SP56 are repeatedly executed.

  On the other hand, when the user performs a predetermined data reading operation on the keyboard 10 of the mobile phone 1, a data reading routine shown in FIG. In the figure, when the process proceeds to step SP2, transmission of the radio wave S1 from the RFID communication unit 16 is started. Therefore, if the antenna 14 is brought close to the RFID tag 30 at that time, the above-described processing of FIG. Next, when the process proceeds to step SP4, it is determined whether or not the data reception is completed based on whether or not the above-described end code has already been received. If not completed yet, it is determined as “NO”, and the process proceeds to step SP8.

  In step SP8, it is determined whether or not a timeout has occurred, that is, whether or not a time equal to or longer than a predetermined maximum time has elapsed after step SP2 has been executed first. If "NO" is determined here, the process proceeds to step SP14, and data supplied from the RFID tag 30 is received through the RFID communication unit 16 for a predetermined time. Next, when the process proceeds to step SP16, it is determined whether or not an error has occurred in the data in the received range. If reception of the end code is completed in step SP14 first, the checksum result included in this end code is compared with the accumulated result of each byte of the trial listening data and associated data received earlier. If they do not match, it is determined that a data error has occurred. Here, if the data is normally received, “NO” is determined, and the process proceeds to step SP18. Here, the data in the received range is stored in the RAM 6, and the process returns to step SP4.

  Thereafter, when data is normally transmitted and received between the mobile phone 1 and the RFID tag 30, the loop composed of steps SP4, SP8, SP14, SP16 and SP18 is repeated, and the received data is stored in the RAM 6. It will be done. Here, when the end code is received by the RFID communication unit 16, it is determined “YES” when the process proceeds to step SP4 next time, and the process proceeds to step SP6. Here, a predetermined reception end message indicating that the data has been normally received is displayed on the display 8.

  On the other hand, if a timeout is detected in step SP8 or if a data error is detected in step SP16, “YES” is determined in any of these steps, and the process proceeds to step SP10. Here, an error message indicating that the data could not be received normally is displayed on the display 8. Then, when the message display is finished in step SP6 or SP10, the process proceeds to step SP12, and the transmission of the radio wave S1 is finished. If the data cannot be received normally, the user may execute the data reading operation again.

  When the user performs a predetermined audition operation on the keyboard 10 after the reception of the audition data and the accompanying data is normally completed by the above processing, the audition routine shown in FIG. In the figure, when the process proceeds to step SP22, reproduction of the trial listening data in the RAM 6 is started. That is, after the step is executed, the trial listening data is sequentially transmitted to the sound source unit 26, and the synthesized musical sound signal is output through the speaker 28. Next, when the process proceeds to step SP24, it is determined whether or not the reproduction of the trial listening data is completed. When it is determined that the reproduction has been completed, the processing of this routine ends.

  Then, as a result of performing the trial listening, if the user desires to use the trial listening data as automatic reproduction data (data that can be automatically reproduced as a ringtone, alarm sound, etc.), registration of the trial listening data A predetermined registration operation is performed by the user. When such a registration operation is executed, a registration processing routine shown in FIG. 3B is started. In the figure, when the process proceeds to step SP32, it is determined whether or not the automatic regeneration permission flag in the RAM 6 is "1". Note that “1” means that the user is allowed to use the audition data as an automatically reproduced sound, and “0” means that this is rejected. If "YES" is determined in the step SP32, the process proceeds to a step SP34, and the audition data in the RAM 6 is transferred to the musical tone signal area in the flash memory 4. As a result, the user can assign the trial listening data as a ring tone or an alarm sound in the same manner as other automatic reproduction data.

  On the other hand, if “NO” is determined in step SP32, the process proceeds to step SP36. Here, a message for guiding the purchase is displayed on the display 8 while notifying the user that it is charged to use the trial listening data as the automatic reproduction data and the amount to be used as the automatic reproduction data. . Further, on this screen, an option of “purchase” or “do not purchase” is shown, and the process waits until one is instructed by the user. And if a user's instruction | indication is input, a process will progress to step SP38. Here, it is determined whether or not “Purchase” is selected. Here, if “not purchase” is selected, it is determined as “NO”, and the processing of this routine is immediately ended.

  On the other hand, if “Purchase” is selected, “YES” is determined, and the process proceeds to step SP40. Here, a predetermined telephone number (the telephone number of the distribution center that performs the sales process of the trial listening data) is called from the telephone communication unit 18, and the accompanying data in the RAM 6 is transmitted to the distribution center. As a result, the user of the mobile phone 1 is charged a usage fee at a later date via the telephone company. Next, when the process proceeds to step SP42, it is determined whether or not the purchase process is successful. If “NO” is determined here, the processing of this routine is immediately terminated. On the other hand, if "YES" is determined, the process proceeds to step SP44, and the automatic regeneration permission flag is changed to "1". Next, when the process proceeds to step SP34, the trial listening data is transferred to the musical tone signal area in the flash memory 4 as automatic reproduction data as described above.

  The automatic reproduction data stored in the musical tone signal area in the flash memory 4 can be freely selected as an automatic reproduction sound such as a ring tone or an alarm sound. That is, when an incoming call is received from another telephone, the automatic reproduction data selected as the ring tone is reproduced. Further, when the alarm function of the mobile phone 1 is turned on and the current time reaches a predetermined alarm time, the automatic reproduction data selected as the alarm sound is reproduced. The contents of these reproduction processes are the same as those in the trial listening routine (FIG. 3 (a)).
