BACKGROUND OF THE INVENTION
The present invention relates to a communication karaoke terminal that receives song data from a distribution center in response to a user's request and performs karaoke performance based on the song data.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a communication karaoke system that distributes karaoke song data stored in a distribution center to a communication karaoke terminal via a communication line such as a telephone line is known. In the communication karaoke terminal in such a system, music data distributed from the distribution center is stored in a large-capacity storage device such as a hard disk device, and music data distributed from the distribution center is stored in a semiconductor such as a RAM. Some of them are temporarily stored in a storage device, and the song data is deleted from the semiconductor storage device after karaoke performance.
[0003]
For example, a commercial karaoke terminal installed in a karaoke box or the like corresponds to the former, and always stores thousands to tens of thousands of song data in the communication karaoke terminal. Karaoke performance is performed based on the song data stored in the terminal. On the other hand, for example, some home-use communication karaoke terminals correspond to the latter, and each time such a communication karaoke terminal receives a request from a user, a song is sent from the distribution center in response to the request. Receive data and perform karaoke performance based on the received song data.
[0004]
In other words, since it is used by unspecified users for business use, there is a high possibility that various songs will be requested, and it is effective to store the song data distributed from the distribution center on a hard disk device etc. However, with home karaoke devices such as those installed in vehicles, the songs requested by users are determined to some extent, so it is bothersome to save various song data in a large-capacity storage device such as a hard disk device. There is no need to keep it. In particular, in the case of what is installed in a vehicle, there is a problem in increasing the size and cost of the device by providing a large-capacity storage device such as a hard disk device, and information is obtained by rotating the disk like a hard disk device. Since a storage device having a structure for reading the song may be vulnerable to vibration, it is desirable that the song data be temporarily stored in a semiconductor storage device such as a RAM.
[0005]
The present invention is the latter type of online karaoke terminal, that is, whenever there is a request from a user, the song data is received from the distribution center in response to the request, and the karaoke is based on the received song data. The present invention relates to a communication karaoke terminal for performing music.
[0006]
In such a communication karaoke terminal, as described above, music data is received from the distribution center each time, so karaoke performance cannot be performed until the reception of the music data is completed. Therefore, conventionally, for example, a predetermined number of karaoke songs such as 10 songs can be requested as reserved songs, and song data corresponding to a request already made during a karaoke performance based on a song data is received from the distribution center. By completing the reception of the next song data by the end of the karaoke performance, when the karaoke performance is completed, the karaoke performance based on the next song data is immediately performed. Continuous performance was realized.
[0007]
[Problems to be solved by the invention]
Now, consider the case where music data is distributed via a mobile communication wireless line using a mobile phone system or the like.
In such so-called mobile communication, the line quality may be deteriorated as a mobile station such as a person with a mobile phone or a vehicle equipped with a car phone moves. That is, the movement of the mobile station may be affected by surrounding buildings, or fading may occur in the received electric field due to the use of multiple standing waves. In such a case, if the state in which the line quality deteriorates for a certain period or more continues, the base station or mobile station is forced to avoid occupying the line in a state in which the line quality is significantly deteriorated from the viewpoint of effective use of frequency. The line is disconnected.
[0008]
Accordingly, when a communication karaoke terminal in the communication karaoke system is installed in a mobile station, there is a possibility that reception of music data may fail due to forced line disconnection when the line quality deteriorates or the line quality continues to deteriorate.
However, the conventional communication karaoke terminal is designed to notify the user of the failure to receive the song data after the end of the karaoke performance and start re-receiving the song data only after receiving an instruction from the user. It was. Therefore, if reception fails, the song data corresponding to the next request after the completion of the performance of the karaoke song, that is, the song data that failed to be received is re-received. There will be a situation where it is not done.
[0009]
The present invention is a case where a song data corresponding to a user's request is received from a distribution center via a wireless line, and a communication karaoke terminal that performs karaoke performance based on the song data fails to receive the song data. In addition, the purpose is to realize the continuous performance of the karaoke music as described above as much as possible.
[0010]
[Means for Solving the Problems and Effects of the Invention]
  The present inventionThroughThe karaoke terminal requests the distribution center to distribute song data in response to a request from the user, receives the song data from the distribution center via a wireless line, and performs a karaoke performance based on the song data. is there. For example,For automotiveThe communication karaoke terminal calls the distribution center, establishes a data communicable state with the distribution center, receives the corresponding song data from the distribution center, and performs karaoke performance. In particular, the present inventionThroughWhen multiple karaoke songs are requested, the karaoke terminal receives song data in parallel with the karaoke performance, and after the karaoke performance is completed, the karaoke performance is immediately performed based on the next song data. Do.
[0011]
At this time, if reception of music data from the distribution center fails, the reception failure determination means determines it. As described above, in mobile communication via a wireless channel, the channel quality may deteriorate as the mobile station moves. By such a line quality degradation or forced line disconnection due to channel quality degradation, Communication may become impossible and reception of music data may fail. Accordingly, the reception failure determination means determines the failure in receiving the music data, for example, based on a checksum in the music data.
[0012]
When it is determined by the reception failure determination means that reception of the music data has failed, the notification means notifies the user of the reception failure. For example, a display unit such as a display using a CRT or a liquid crystal may be provided, and notification may be made visually through the display unit, or notification may be made through hearing with a predetermined sound.
[0013]
  Here, when the user recognizes that reception of the song data has failed by notification by the notification means, and instructs the re-reception via the input means, the instruction determination means receives the re-reception instruction from the user. Judge that. Input means hereIsIt is possible that it is an operation unit provided in the Shin Karaoke terminal, orIsIt is also possible that the remote controller is prepared separately from the Shinkarakara terminal body.
[0014]
  When it is determined by the instruction determining means that there is a re-reception instruction from the user, the line connection executing means calls the distribution center and executes the line reconnection operation. As a result, when the distribution center responds, a data communication possible state is established again with the distribution center. Here, when the distribution center does not respond and the line connection is not made, the line connection execution means may execute the reconnection operation repeatedly for a predetermined number of times. When the data communication possible state is established again with the distribution center, the redistribution request means requests the distribution center to redistribute the song data that has failed to be received.The
[0015]
  As a result, the song data that failed to be received is distributed again from the distribution center.EThe Shin Karaoke terminal receives this song data. In the basic functions described above, in particular, the present invention.ThroughIn the shin karaoke terminal, the notification means notifies the user of the reception failure even during the karaoke performance.
[0018]
  By the way, when it is notified that reception of song data has failed, the user wants to stop receiving only the song data, and when other requests are made, all requested karaoke songs Sometimes you want to stop receiving song data corresponding to. For example, as mentioned above, considering the acquisition of song data in a moving vehicle, the radio wave condition may not be recovered easily, and all requests that have been made, such as when multiple reception failures occur There arises a situation where it is desired to stop receiving the song data corresponding to the karaoke song. However, in the case of the former, that is, when the song data that failed to be received is not re-received and the song data corresponding to the next request is to be received, the reception may be completed by the end of the karaoke performance. DesiredYes.
  Therefore,The notification means is configured to notify the user of reception failure even during the karaoke performance, and the line connection execution means is determined by the reception stop instruction determination means that there is no reception stop instruction from the user. If a reconnection operation to the line is executed and the data communication possible state is reestablished with the distribution center by executing the reconnection operation, distribution of music data according to another request is distributed. It is configured to request to the center.
  The conventional communication karaoke terminal is designed to notify the user of the failure to receive the song data after the end of the karaoke performance, and start receiving the song data again only after receiving an instruction from the user. Therefore, if reception fails, the song data corresponding to the next request after the completion of the performance of the karaoke song, that is, the song data that failed to be received is re-received. There will be a situation where it is not done.
  On the other hand, in the communication karaoke terminal of the present invention, when the reception failure determination means determines that the reception of the song data has failed, the notification means informs the user of the reception failure even during the karaoke performance. Inform. Then, when the user instructs re-reception, the reception of the music data that has failed to be received is started again, so that it is highly possible that the music data corresponding to the next request can be received before the end of the karaoke performance. Therefore, there is a high possibility that karaoke songs can be continuously played.
  In this case, when there is no re-reception instruction from the user and another request has been made, the user is notified that another request has been made. For example, when a request for five songs is made and the song data that has failed to be received corresponds to a request for “second song”, the other requests are “third song”, “fourth song”, and “fifth song”. A request. When the user is notified that another request has been made, the user instructs whether to stop the reception via the input means. When it is determined by the reception stop instruction determining means that there is no reception stop instruction from the user, the line connection executing means executes the reconnection operation to the line, and the data communication possible state again with the distribution center is resumed. When established, the distribution center is requested to distribute music data according to other requests. At this time, when it is determined that there is a reception stop instruction from the user, all the request information stored in the apparatus may be deleted, or stored in the apparatus as it is, and then used. The distribution center may be requested to distribute music data in response to another request according to an instruction from the person.
  With such a configuration, even when re-reception of song data that has failed to be received is stopped, if another request has been made, the song data corresponding to the request will be sent by the end of the karaoke performance. The possibility that it can be received increases, and the possibility that a continuous performance of karaoke songs can be realized.
  In the above-described configuration, when it is determined that the music data reception has failed, the notification means immediately notifies the user of the reception failure.2As shown in FIG. 4, the line connection execution means further executes the line connection operation when the reception failure determination means determines that the music data reception has failed, and the notification means executes the line connection operation. Thus, it is conceivable that the user is notified of the reception failure when the data communication possible state is not established with the distribution center. Here, the execution of the line connection operation by the line connection execution means is not limited to one time. For example, the line connection operation is executed a predetermined number of times, for example, five times. If the data communicable state is not established, it is also conceivable that the notifying means notifies the user of reception failure. On the other hand, when a data communication possible state is established with the distribution center by executing the line connection operation, the redistribution request means receives the notification without notifying the user of the failure to receive the song data. Request redistribution of song data that failed.
[0019]
In other words, even if reception of music data fails, reconnection to the line is automatically performed without being able to make a connection, and if data communication is possible with the distribution center, Only when the data is re-received and the data communicable state is not established, the reception failure is notified to the user. As a result, when the data communication state is established with the distribution center, re-reception of the song data that has failed to be received is started without waiting for the user's instruction. The possibility that song data can be acquired is increased, and the possibility that continuous performance of karaoke songs can be realized.
[0020]
  By the way, claims1As described above, the line connection executing means executes the line connection operation by repeating the predetermined number of times, for example, five times when the data communicable state is not established with the distribution center by executing the line connection operation. However, for example, when acquiring song data in a moving vehicle, if the vehicle enters the tunnel, the line as described above is required for several minutes before exiting the tunnel. Even if the reconnection operation is performed, it is useless. Thus, a certain amount of time may be required until there is no cause for communication failure. Therefore, when considering line connection operation as efficiently as possible,3It is conceivable to adopt the configuration shown in FIG. That is, the configuration further includes a radio wave reception state detection unit that detects a radio wave reception state and a radio wave reception state determination unit that determines whether or not the radio wave state detected by the radio wave reception state detection unit is good. The line connection execution means is configured to execute the line connection operation after waiting for the radio wave reception state to be good based on the determination result by the radio wave reception state determination means. In this case, the radio wave reception state detecting means detects the radio wave reception state. As an example, it is conceivable that the radio wave reception state detection means detects the received electric field strength of radio waves. Then, based on the detected radio wave reception state, the radio wave reception state determination unit determines whether or not the radio wave reception state is good. Based on the determination result, the line connection execution means waits until the radio wave reception state becomes good and performs the reconnection operation to the line. As a result, the line connection with the distribution center can be surely performed, and useless line connection operations can be suppressed.
[0025]
The above is a description of the configuration as a communication karaoke terminal and its operation and effects. However, data is provided between the communication karaoke terminal described above, a distribution center that distributes song data to the communication karaoke terminal, and the communication karaoke terminal and the distribution center. It can also be realized as a communication karaoke system provided with a communication network that establishes a communicable state.
[0026]
Since the effects when realized as an online karaoke system are the same as those realized as an online karaoke terminal, they are omitted here.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a communication karaoke system 1 of the present embodiment.
[0028]
The communication karaoke system 1 includes a communication karaoke terminal 10, a distribution center 40 that stores karaoke song data, and a communication network 50 for distributing song data from the distribution center 40 to the communication karaoke terminal 10. ing. This communication line network 50 includes a mobile station wireless line network 50a, and the communication karaoke terminal 10 establishes a data communicable state with the distribution center 40 via the wireless line network 50a.
[0029]
The communication karaoke terminal 10 is mounted on a vehicle, and includes a main unit 17 indicated by a broken line in FIG. 1, a mobile phone 23 connected to the main unit 17, a microphone 21 for inputting a user's voice, and lyrics. Display unit 22 which is a liquid crystal display for displaying a telop, operation unit 24 for instructing re-reception or reception stop of a karaoke song request and song data to be described later, FM receiving unit 31 provided in the vehicle, and acoustic adjustment The unit 32 and the speaker 33 are provided. As described above, the communication karaoke terminal 10 is configured using the FM receiver 31, the acoustic adjustment unit 32, and the speaker 33 that are provided in the vehicle.
[0030]
As shown in FIG. 1, the main unit 17 includes a control unit 11, a RAM 12, a data communication unit 13 that performs data communication with the distribution center 40 via the mobile phone 23 described above, and a lyrics for the display unit 22 described above. A video control unit 16 that outputs telop data, an audio control unit 14, and an FM transmission unit 15 that modulates the frequency of the karaoke accompaniment signal output from the audio control unit 14 and transmits the karaoke accompaniment signal via the transmission antenna 15a. ing. The voice control unit 14 is also connected to the microphone 21 described above, and outputs the input user's voice as a voice signal to the FM transmitter 15 together with the karaoke accompaniment signal. The karaoke accompaniment signal and audio signal transmitted from the FM transmitter 15 are received by the FM receiver 31 described above via the receiving antenna 31a, the acoustic adjustment unit 32 performs amplification and acoustic adjustment, and the accompaniment sound is output from the speaker 33. And audio are output.
[0031]
Here, the mobile phone 23 is a general mobile phone that has been sold conventionally, and is connected to the data communication unit 13 via a data communication connector (not shown) of the mobile phone 23. The cellular phone 23 has a data communication antenna 23a, and performs data communication with the distribution center 40 via the communication line network 50 using the data communication antenna 23a.
[0032]
Next, operation | movement of the communication karaoke system 1 of this embodiment is demonstrated.
When a karaoke song is requested from the user via the operation unit 24, the request information is stored in the RAM 12 as reserved song information. In the communication karaoke terminal 10 of the communication karaoke system 1 of the present embodiment, it is assumed that reserved song information of up to 10 songs can be stored.
[0033]
When reserved song information is stored in the RAM 12, the control unit 11 instructs the data communication unit 13 to acquire song data based on the reserved song information. The data communication unit 13 calls the distribution center 40 using the mobile phone 23, and when communication with the distribution center 40 is established, the data communication unit 13 performs data communication with the distribution center 40 and receives corresponding music data. The song data received by the data communication unit 13 is stored in the RAM 12. When song data that is a reserved song is stored in the RAM 12, the control unit 11 reads the song data and starts karaoke performance.
[0034]
The video control unit 16 outputs the lyrics telop data to the display unit 22 based on the lyrics data in the read song data. As a result, the lyrics telop is displayed on the display unit 22. On the other hand, the audio control unit 14 converts MIDI data, which is performance data in the read music data, into a karaoke accompaniment signal and outputs the karaoke accompaniment signal to the FM transmission unit 15. In addition, an audio signal input via the microphone 21 is also output to the FM transmitter 15. The FM transmitter 15 frequency-modulates the karaoke accompaniment signal and the audio signal, and transmits them to the FM receiver 31. The FM receiver 31 receives the karaoke accompaniment signal and the audio signal, and the accompaniment sound and the audio are output from the speaker 33 via the acoustic adjustment unit 32.
[0035]
Thereby, the user can sing along the accompaniment sound output from the speaker 33 while referring to the lyrics telop displayed on the display unit 22 for the requested karaoke song.
In addition, when the reserved music information is memorize | stored in RAM12, the control part 11 receives applicable music data based on reserved music information as mentioned above in parallel with a karaoke performance. Then, the received song data is stored in the RAM 12, and when the karaoke performance is completed, the karaoke performance is immediately started based on the song data stored in the RAM 12. That is, when a plurality of request information is stored as reserved song information in the RAM 12, the communication karaoke terminal 10 performs a continuous performance of karaoke songs corresponding to the reserved song information.
[0036]
However, in the so-called mobile communication via the wireless network 50a, the line quality may deteriorate as the vehicle equipped with the mobile phone 23 moves. In other words, the movement of the vehicle may be affected by surrounding buildings, or fading may occur in the received electric field due to the use of standing waves by multiple waves. In such a case, if the state in which the channel quality is deteriorated for a certain time or more continues, the base station of the radio network 50a can be used to avoid occupying the channel in a state in which the channel quality is significantly deteriorated from the viewpoint of effective use of frequency. Alternatively, the line is forcibly disconnected by the mobile phone 23 mounted on the vehicle. Therefore, in the communication karaoke terminal 10 in the communication karaoke system 1, there is a possibility that the reception of the music data described above may fail due to forced line disconnection when the line quality deteriorates or the line quality deteriorates continuously.
[0037]
Then, next, the reception process performed in the communication karaoke terminal 10 of this embodiment is demonstrated in detail based on the flowchart shown in FIG. This reception process is executed by the control unit 11 of the communication karaoke terminal 10.
First, in the first step S100, it is determined whether or not reserved song information is stored in the RAM 12. As described above, in this embodiment, when a karaoke song is requested from the user via the operation unit 24, the request information is stored in the RAM 12 as reserved song information. If it is determined that reserved song information is stored (S100: YES), the process proceeds to S110. On the other hand, if it is determined that the reserved music information is not stored (S100: NO), this reception process is terminated.
[0038]
In S110, a distribution request to the distribution center 40 is made. This process instructs the data communication unit 13 to acquire song data based on the reserved song information stored in the RAM 12. The data communication unit 13 calls the distribution center 40 using the mobile phone 23, and when communication with the distribution center 40 is established, the data communication unit 13 performs data communication with the distribution center 40 and notifies request information such as a song number. And request distribution of song data.
[0039]
In subsequent S120, it is determined whether or not reception of music data for one music has been completed. If it is determined that the reception has been completed (S130: YES), the process proceeds to S100. If there is reserved music information (S100: YES), a distribution request is made (S110), and reception of music data in response to the next request is started. However, if a data communication enabled state has already been established with the distribution center 40 in S110, the calling process is not performed.
[0040]
In S130, the music data distributed from the distribution center 40 in response to the distribution request in S110 is received. The song data is distributed, for example, in units of frames and is received sequentially.
In S140, it is determined whether or not reception of the music data has failed. Here, for example, with reference to checksums in sequentially received data, if the checksum value becomes abnormal continuously, it is determined that the music data reception has failed. If it is determined that the reception of the music data has failed (S140: YES), the line established with the distribution center 40 is temporarily disconnected, and the process proceeds to S150. On the other hand, if it is determined that the reception of the music data has not failed (S140: NO), the received data is stored in the RAM 12, and the process proceeds to S120.
[0041]
In S150, reception failure display is performed. This process notifies the user that reception of music data has failed. Here, predetermined message data is output to the video controller 16. As a result, the video control unit 16 displays a message based on this message data on the display unit 22. For example, FIG. 3A shows a display example during karaoke performance. Here, messages such as “Failed to download song number XX-XXX”, “Do you want to download again?”, “Yes”, “No” are displayed. In addition, during the karaoke performance, the video control unit 16 displays the lyrics telop in the area B (the area indicated by the broken line in FIG. 3) of the display unit 22, and the message described above displays the lyrics telop. The image is displayed in a display area A (area indicated by a one-dot chain line in FIG. 3) that does not overlap with the area B. Therefore, it is not difficult to see the lyrics telop due to the reception failure display.
[0042]
In subsequent S160, an instruction from the user is determined. This process is to determine an instruction input from the user via the operation unit 24. When a reception failure display is made in S150, the user moves the cursor C in FIG. 3A via the operation unit 24 in response to the display “Do you want to download again”? Select either “Yes” or “No”. If “Yes” is selected here, that is, if there is an instruction to perform re-reception, the process proceeds to S170. On the other hand, if “No” is selected, that is, if there is an instruction not to perform re-reception, the process proceeds to S180.
[0043]
In S170, redistribution of music data is requested. This process instructs the data communication unit 13 to acquire song data that has failed to be received. When the data communication unit 13 calls the distribution center 40 again with the mobile phone 23 and establishes a communicable state with the distribution center 40, the data communication unit 13 performs data communication with the distribution center 40, and receives the music data that has failed to be received. Request redelivery. As a result, the music data is redistributed from the distribution center 40. Thereafter, the process proceeds to S130, and the subsequent processing is repeated.
[0044]
If the reception of the song data has failed, and the process proceeds to S180 when the user instructs not to receive the song data again, it is determined whether or not the reserved song information is stored in the RAM 12. This process is to determine whether there is a request after the request corresponding to the music data that has failed to be received. If it is determined that there is reserved music information (S180: YES), the process proceeds to S190. On the other hand, if it is determined that there is no reserved music information (S180: NO), this reception process is terminated.
[0045]
In S190, a reception cancellation inquiry display is performed. Here, predetermined message data is output to the video controller 16. As a result, the video control unit 16 displays a message based on this message data on the display unit 22. For example, a display example during karaoke performance is shown in FIG. Here, the message “Do you want to cancel all requests and cancel the download?”, “Yes”, “No” is displayed. Similarly to the processing of S110, the video control unit 16 displays the lyrics telop in the area B (the area indicated by the broken line in FIG. 3) of the display unit 22 during the karaoke performance, and the message described above. Is displayed in a display area A (area indicated by a one-dot chain line in FIG. 3) that does not overlap the display area B of the lyrics telop. For this reason, it is not difficult to see the lyrics telop by this cancel inquiry display.
[0046]
In continuing S190, the instruction | indication from a user is judged. This process is to determine an instruction from the user input via the operation unit 24. When an inquiry to cancel reception is displayed in S190, the user responds to the display “Do you want to cancel all requests and cancel the download?” Via the operation unit 24, the user moves the cursor in FIG. Move C and select “Yes” or “No”. If “Yes” is selected here, that is, if cancellation of the request is instructed, the process proceeds to S210. On the other hand, when “No” is selected, that is, when the continuation of reception based on the request is instructed, the processing from S100 is repeated. As a result, the next song data is received based on the reserved song information.
[0047]
In S210, all reserved music information stored in the RAM 12 is deleted, and then this reception process is terminated.
Next, the effect which the communication karaoke system 1 of this embodiment exhibits is demonstrated.
In the communication karaoke terminal 10 in the communication karaoke system 1 of this embodiment, when reception of music data is started, the control unit 11 executes the reception process shown in FIG. 2 in parallel with the karaoke performance. If it is determined that the reception of the song data has failed (S140 in FIG. 2: YES), the video control unit 16 displays a message on the display unit 22 even during the karaoke performance (in FIG. 2). S150), the user is notified of the reception failure. Then, when the user instructs re-reception (S160 in FIG. 2: “Yes”), in order to request re-distribution of music data that has failed to be received (S170 in FIG. 2), by the end of the karaoke performance There is a high possibility that music data corresponding to the next request can be received. Therefore, there is a high possibility that continuous performance of karaoke songs can be realized.
[0048]
In the online karaoke terminal 10 of the present embodiment, when there is an instruction not to re-receive the song data that has failed to be received (S160 in FIG. 2: “No”), the RAM 12 stores other reserved song information. Is stored (S180 in FIG. 2: YES), a reception cancellation inquiry display is performed (S190 in FIG. 2). Here, if the user has not instructed the reception stop, that is, if the user has instructed the continuation of the reception (S200 in FIG. 2: “No”), based on the reserved song information stored in the RAM 12 Reception of the next song data is started (S110 and S130 in FIG. 2). As a result, there is a possibility that the song data corresponding to the request can be received before the end of the karaoke performance even if the re-reception of the song data that has failed to be received is not performed. The higher the possibility, the higher the possibility of realizing a continuous performance of karaoke songs.
[0049]
The control means 11 in the communication karaoke terminal 10 of the present embodiment corresponds to “reception failure determination means”, “instruction determination means”, and “reception stop instruction determination means”, and includes the control section 11, the data communication section 13, and the mobile phone. 23 corresponds to “line connection execution means” and “redistribution request means”, and the control unit 11, the video control unit 16, and the display unit 22 correspond to “notification means” and “request status notification means”. 2, the process of S140 corresponds to the process as the reception failure determination unit, and the process of S150 corresponds to the process as the notification unit. Further, the process of S160 corresponds to the process as the instruction determination unit, the processes of S110 and S170 correspond to the process as the line connection execution unit, and the process of S170 corresponds to the process as the redistribution request unit. Further, the process of S190 corresponds to a process as request status notification means, and the process of S200 corresponds to a process as reception stop instruction determination means.
[0050]
As described above, the present invention is not limited to such an embodiment, and can be implemented in various forms without departing from the gist of the present invention.
For example, in the above embodiment, when it is determined that the reception has failed (S140 in FIG. 2: YES), the reception failure is immediately displayed (S150 in FIG. 2), but the reception has failed. After determining this, the data communication unit 13 may be automatically instructed to acquire song data that has failed to be received. When the data communication unit 13 calls the distribution center 40 using the mobile phone 23, the distribution center 40 does not respond and the data communication state is not established with the distribution center 40. The same reception failure display may be performed. On the other hand, when the data communication state is established with the distribution center 40, the music data that has failed to be received may be automatically re-received. In this case, if a data communication state is established with the distribution center 40, re-reception of the song data that has failed to be received is started without waiting for the user's instruction. The possibility that the next song data can be acquired is increased, and the possibility that continuous performance of the karaoke song can be realized is further increased.
[0051]
Further, in the above embodiment, although not particularly limited, when the data communication unit 13 calls the distribution center 40 by the mobile phone 23, communication with the distribution center 40 is possible in one call processing. Since there may be a case where the state is not established, the calling process may be repeated a predetermined number of times. Furthermore, the mobile phone 23 generally uses a radio wave reception field strength detection function, and the data communication unit 13 waits for the radio wave state to be good based on the reception field strength detected by the mobile phone 23. Then, the distribution center 40 may be called. With this configuration, it is possible to reliably establish a data communication state with the distribution center 40, and to suppress useless call processing to the distribution center 40.

Furthermore, the communication karaoke terminal 10 according to the above embodiment uses the FM receiver 31, the sound adjustment unit 32, and the speaker 33 that are provided in the car, and includes components that are separate from the main unit 17. You may comprise a karaoke terminal in an integrated type. That is, the FM transmitter 15 and the FM receiver 31 are eliminated, and the sound adjustment unit 32 is directly connected to the sound control unit 14, and the speaker 33 is connected to the sound adjustment unit 32. May be. The communication karaoke terminal 10 may be anything that calls the distribution center 40 based on the user's request, receives the song data according to the request, and performs the karaoke performance, and is not particularly mounted on the vehicle. May be.
