2. Description of the Related Art Generally, in a karaoke apparatus installed in a restaurant or home, accompaniment music information of a desired music piece,
Background image information and lyrics character information are stored in advance in a storage medium such as a laser disk. Then, when the user selects a desired music piece, if there is a back chorus, the back chorus is overlapped with the accompaniment sound to be reproduced, and the background image is displayed, and at the same time, the lyrics characters are displayed on this image. It is widely known that the color of the lyric characters changes according to the accompaniment so that the user can easily sing. In such a karaoke device,
As for songs other than those stored in the laser disc, it is not possible to use them, and if not only songs that are frequently used but also songs that are rarely used are collected, the cost associated therewith becomes enormous, Not realistic.

Further, even when a new song appears and it is desired to sing it with the karaoke apparatus, the new song is
It cannot be sung until it is cut as a laser disk for a karaoke playing device and is on the market, and it has to wait, for example, several months before it can be used. Therefore, as a means for solving these problems at once, a communication karaoke device has been recently developed. In this online karaoke device, the center has a database with information on many types of songs that have been released, as well as previously released songs, and the selected ones are distributed to individual users via telephone lines as needed. The user selects and uses the distributed music. With this online karaoke device, each time the user selects a song,
A non-accumulation type device or a user who distributes information about selected songs from the center side and a user have a large-capacity storage medium, such as a hard disk, in which information about frequently used songs is stored. There is a storage type device that selects and uses a desired music piece from the stored data. This storage type device tends to be widely used because the cost of the communication line is smaller than that of the non-storage type device.

The data in the storage medium of this storage-type device can be updated every day or when necessary when the usage rate of the telephone line is low, such as at night, and distributed early. By the way, the performance of electronic musical instruments such as synthesizers and electronic pianos has been remarkably improved due to technological progress, and the information that drives them is specified for the transmission of digitally encoded signals, such as music information. MIDI (M
musical Instrument Digital
It is transmitted according to the Interface standard. Here, MIDI refers to a standard of hardware and software defined to enable information exchange by connecting with a sound source such as a musical instrument such as a synthesizer or an electronic piano.

By using this MIDI standard, it becomes possible to efficiently transmit an electronic musical instrument control signal. Further, other information not belonging to the MIDI standard, for example, lyrics character information and still image information is transmitted by a signal by a reversible arithmetic compression method, and chorus information is PCM (Pulse C
mode modulation) signal and MPEG (Mo
Ving Picture Image Cordin
An audio signal of g Experts Group) will be transmitted by a signal formatted by the coding method. The information stored in the storage device of the karaoke device is read and played according to the user's selection of music, and the user refers to the lyrics characters displayed on the display in accordance with the accompaniment music to be played. I will sing.

Generally, a karaoke device, which is a terminal, is provided to users at various locations throughout the country. However, it is extremely complicated to manage all of them by one center device, which is enormous. It needs a lot of information. For example, from the center device, in addition to music information (music information, text information, etc.), commercial information in a specific area or weather forecast information in a specific area may be distributed. May be in fashion. In such a case, it is very complicated in terms of management to transmit specific information from one center device to only a terminal karaoke device installed in a specific area, for example, a Hokkaido area or a certain city area, and Depending on the location, the communication cost will be very high.

Therefore, for the purpose of reducing management, a system has been proposed in which a plurality of sub-center devices are provided in the lower layer of the main center device, and the sub-center device mainly manages individual terminal karaoke devices. . Even in this case, needless to say, the main center device and the individual terminal karaoke devices can directly transmit and receive information when necessary. In this case, the management of each terminal karaoke device is outsourced to each sub-center device. However, if each sub-center device can freely transmit and receive information to and from the terminal karaoke device, each terminal karaoke device There is also information transmitted collectively from the main center device, and such information may be overpainted and erased by the information transmitted from the sub center device. Alternatively, the music information may be corrected and re-distributed from time to time, but at this time, the re-distributed music information may be erased by the distribution information from the sub-center device. Therefore, such inconvenience is solved. In order to do so, there is a problem that some kind of check must be performed before the distribution of the sub-center device to improve the security of information.

The present invention focuses on the above problems,
It was devised to effectively solve this, and prior to the distribution of information, the main center device, the sub-center device, the terminal karaoke device , which has improved security by receiving the authentication, that is, the identification code from the main center device , Online karaoke information distribution system and information distribution using these
To provide a belief method .

The reproducing means 12 reproduces MIDI information, chorus information, lyric character information and the like read from the main storage section 9 through the control means 8 based on the music selection information from the input means 11. The accompaniment music and chorus that have been reproduced are mixed by the mixer section 14 and then further mixed by the amplifier 17 together with the singing voice input from the microphone 13 and output as sound by the speaker 15. Also, at the same time as playing the selected song,
The moving picture information selected according to the music type is read out from the moving picture information storage unit 10 via the control means 8, and while displaying this on the display 16, superimposes the lyrics character information reproduced by the reproducing means 12. It is designed to be paused and displayed in layers.

2 and 3 show a communication karaoke information distribution system of the present invention in which the center device and the terminal karaoke device thus constructed are combined with each other. Here, there are a main center device 1A and a sub-center device 1B as center devices, and these devices and between these devices and the terminal karaoke device 3 are mutually connected by a public line network 4 so that bidirectional transmission can be performed. Has become. The main center device 1A puts the sub-center device 1B and the terminal karaoke device 3 under its control, and the sub-center device 1B has the terminal karaoke device 3 under its control and has a so-called three-layer structure. Although only one device is shown in each of the illustrated examples, the main center device 1A puts a plurality of sub-center devices 1B under control, and each sub-center device 1B puts a plurality of terminal karaoke devices 3 under control. Put on. Here main center apparatus 1A includes a first origination
The sub-center device 1B corresponds to the second invention , and the terminal karaoke device 3 corresponds to the fifth invention .

The terminal karaoke device 3 is used to identify the device in addition to the configuration described in FIG. 1, for example, the interface 6, the control means 8, the main storage section 9, the input means 11, the reproducing means 12, the terminal transmitting / receiving section 19. An identification code (hereinafter referred to as an ID) that is given differently for each terminal karaoke device
An identification code storage unit 20 for storing the ID and a terminal transmission instruction unit 21 for instructing to transmit the ID when a communication request from the outside is made are provided so that the communication partner can identify the self device. Has become. This terminal karaoke device 3 will be installed in the store etc. of each user.

On the other hand, the main center device 1A, which corresponds to the first outgoing <br/> bright, interface 5A, the main communication unit 1 for transmitting and receiving information to and from each device
8A, in addition to information about music, user name, its ID,
In addition to a large-capacity main storage unit 2A that stores various types of information such as information numbers, for example, a main center control unit 7A including a microcomputer or the like, a user name and information number transmitted from the sub-center apparatus 1B, and the main Storage unit 2
A main comparison unit 22 that is a feature of the present invention that compares the stored contents of A and a main transmission instruction unit 23 that instructs to transmit the ID corresponding to the user name to the sub-center device according to the result of the comparison unit 22. have. In reality, the functions of the comparison unit 22 and the transmission instruction unit 23 are realized by the software of the computer.

On the other hand, the sub-center device 1B corresponds to the second aspect of the invention, and the sub-transmission / reception unit 1 for transmitting / receiving information to / from the interface 5B and each of the devices.
8B, a large-capacity sub storage unit 2B for storing various information such as a user name, main body information, and an information number attached to the sub-center control unit 7B including a microcomputer, etc. In addition to the input means 24, the present invention for transmitting the user name of the terminal karaoke apparatus 3 and the information number of the body information desired to be transmitted to the main center apparatus 1A before transmitting predetermined body information to the terminal karaoke apparatus. In response to receiving the ID information of the terminal karaoke device desired to be transmitted from the first sub-transmission instructing section 25 and the main center device 1A, the main body information is transmitted to the terminal karaoke device 3 concerned. The ID transmitted from the terminal karaoke apparatus at the start of transmission between the second sub transmission instruction unit and the terminal karaoke apparatus is transmitted from the main center apparatus 1A. Has a sub identification code checking section 27 for checking whether consistent with been ID, actually to feed the body information only when both ID match.

The point to be noted here is the sub-center unit 1B.
, The user name of each user who installed the terminal karaoke device is given, but the ID information is not given, and the point is that the main center device 1A sends the ID information when necessary. It is checked whether or not the information numbers (different numbers are assigned to the respective body information) are duplicated, and protection is applied when necessary. An example of the stored contents in each storage unit at this time is shown in FIGS. 4 and 5. FIG. 4 is a diagram showing the stored contents of the main storage unit 2A, and FIG. 5 is a diagram showing the stored contents of the sub storage unit 2B. In the main storage unit 2A shown in FIG. 4, a user name, an ID, main body information, and an information number attached to this are stored for each user. This body information means one piece of information, and corresponds to, for example, individual music information or weather forecast information for each music. Therefore, it is necessary to prevent the main body information having different contents from being delivered from the sub-center device to the terminal karaoke device 3 based on the same information number. On the other hand, in the sub storage unit 2B shown in FIG.
A user name, body information, and an information number attached to this are stored for each user. Here, the ID of the user name is not given as described above, and if this ID is not given, it is impossible to actually transmit to the terminal.

Next, the flow of actual information distribution in such a system will be described. First, an example will be described in which the sub-center apparatus 1B is requested to deliver certain body information, for example, weather forecast information of a specific area, to the terminal karaoke apparatus 3 under its control. In this case, first, the first sub transmission instructing unit 25 causes the sub transmitting / receiving unit to transmit the user name to be delivered and the information number attached to the weather forecast information to the main center device 1A. The sub-transmission / reception unit 18B, which has instructed 18B and receives the instruction, transmits the information to the main center apparatus 1A via the interface 6A and the public line network 4. The transmitted information is taken into the main comparison unit 22 via the interface 5A and the main transmission / reception unit 18A in the main center device 1A, and the user name and information number are stored in the main storage unit 2A. It is checked whether or not there is the same information number for the same user name by matching the stored contents.

As a result of the judgment by the main comparing section 22, if there is no one having the same information number for the same user name, the necessary information stored in the terminal karaoke apparatus 3 is overpainted and erased. Therefore, the main transmission instruction unit 23 instructs the main transmission / reception unit 18A to return the ID of the terminal karaoke device to the sub-center device 1B, and this ID information is transmitted to the sub-center device 1B. Further, when there is the same user name with the same information number in the main comparison unit 22, the ID information is not transmitted in order to prevent the distribution of the weather forecast information.

Upon receiving the ID information, the sub-center unit 1B
The second sub-transmission instructing unit instructs the sub-transmission / reception unit 18B to transmit the main body information, that is, the weather forecast information to the corresponding terminal karaoke device based on the ID information. Then,
Transmission from the sub-center apparatus 1B to the corresponding terminal karaoke apparatus 3 via the public line network 4 is started. At the start of this transmission, the terminal karaoke apparatus 3 has the identification code storage unit 20.
The ID information stored in 1 is sent back to the sub-center apparatus 1B according to an instruction from the terminal transmission instruction section 21. This ID
Upon receiving the information, the sub-identification code inspection unit 27 of the sub-center apparatus 1B checks whether the ID information sent from the terminal and the ID information previously sent from the main center apparatus 1A match, and they match. At times, it is instructed to send the body information as it is, and the body information is actually transmitted. Here, if the ID information does not match, it is needless to say that the main body information is not transmitted because it is not a correct terminal.

As described above, before the sub-center apparatus 1B actually transmits to the terminal karaoke apparatus, the information number is checked by the main center apparatus 1A to receive this permission, and then the main body information is actually transmitted. Therefore, the security of the stored contents of the terminal karaoke device 3 can be maintained. In other words, it is possible to prevent the sub-center device 1B from randomly erasing the stored contents of the terminal karaoke device regardless of good intention or bad intention. The above operation will be further described with reference to the flowchart shown in FIG.
First, when the sub-center apparatus 1B has delivered predetermined body information to the terminal karaoke apparatus 3, the main center apparatus 1A in the connection waiting state is called (S1), and the line between them is connected (S2). Next, the sub-center device 1B
Requests the terminal ID by transmitting the user name and the information number to the main center device 1A (S3). Here, the main center apparatus 1A checks whether or not the sent user name and information number are valid, and if valid, returns the terminal ID information to the sub center apparatus 1B (S4). . In addition, if it is not appropriate here, the fact is returned to the sub-center apparatus 1B and the subsequent transmission is stopped. The sub-center apparatus 1B that has acquired the terminal ID disconnects the line with the main-center apparatus 1A (S5).

Next, the sub-center apparatus 1B which has acquired the terminal ID calls the terminal karaoke apparatus 3 in the connection waiting state (S6) and connects the line between them (S7). Then, the sub-center apparatus 1B requests the terminal for the ID (S8), and in response, the terminal karaoke apparatus 3 responds to the ID of its own.
D is returned (S9). The sub-center apparatus 1B which has received the returned ID determines whether or not the returned ID is valid, and if it is valid, the main body information is actually delivered to the terminal karaoke apparatus 3 (S10). . If the ID returned here is invalid, the line is immediately disconnected as NG (No Good). When the return ID is valid and the distribution of all the information is completed (S11), the line is disconnected (S12), and the distribution of the predetermined information is completed. In the above invention, the sub-center device 1B receives the ID of the terminal karaoke device 3 from the main center device 1A, and based on this, the sub-center device 1B itself transmits the main body information to the terminal karaoke device. Alternatively, the sub-center device 1B may transmit the main body information to the main center device 1A, and the main center device 1A may be entrusted with the distribution of the main body information to the terminal karaoke device 3.

FIG. 7 is a block diagram showing such another communication karaoke distribution system of the present invention. The same parts as those shown in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. In the main storage unit 2A of the main center apparatus 1A, a user name, an ID corresponding to the user name, restriction rules regarding body information, and the like are stored in addition to the information regarding music as shown in FIG. This restriction regulation includes, for example, a regulation on the format of the body information and a regulation of the maximum capacity that one body information can take, and the body information transmitted from the sub-center device 1B is in each of the above-mentioned regulations as described later. Check for a match. The main comparison unit 22 compares the user name and the body information transmitted from the sub-center device 1B with
A comparison is made with the stored contents of the main storage unit 2A. The main transmission instruction unit 23 is the main comparison unit 2 described above.
According to the comparison result of 2, the main body information is transmitted to the terminal karaoke device corresponding to the user name in a predetermined case.
Here, for example, as a result of the above comparison, if the capacity or format of the main body information is inappropriate, the main center apparatus does not transmit the main body information to the terminal, and the sub center apparatus 1B is denied to notify that fact. Transmit signal.

The main identification code inspecting unit 28 receives the I sent from this terminal when the transmission to the terminal karaoke apparatus is started.
It is checked whether D matches the corresponding ID in the main storage unit 2A, and the body information is actually transmitted only when the ID matches. On the other hand, a user name and body information are stored in the sub storage unit 2B of the sub center device 1B as shown in FIG. Here, as in the case described above, the user ID is not given in order to prevent the sub-center apparatus 1B from transmitting information to the terminal without the permission of the main-center apparatus 1A. The information number is not given on the side of the sub center device 1B, but it is given on the side of the main center device. The first sub-transmission instruction section 25 transmits the user name and body information to the main center apparatus 1A when it becomes necessary to supply the body information to a predetermined terminal karaoke apparatus. Here, since the distribution of the main body information is outsourced to the main center device, the second sub transmission instruction unit 26 and the sub identification code inspection unit 27 shown in FIG. .

In such a system, when the sub-center device 1B supplies main body information such as weather forecast information to the terminal karaoke device 3 under its control, the distribution is entrusted to the main center device 1A. First, the first sub transmission instruction unit 25 instructs the sub transmission / reception unit 18B to transmit the user name to which the main body information is to be supplied and the main body information to the main center device 1A, and the sub transmission / reception unit 18 that has received the instruction
B transmits the information to the interface 6A and the public network 4.
It transmits to the main center apparatus 1A via. The transmitted information is taken into the main comparison unit 22 via the interface 5A and the main transmission / reception unit 18A in the main center device 1A, where the capacity and format of the user name and the main body information are stored in the main storage unit 2A. It is checked whether or not the stored contents are matched, the user name is registered, and the capacity of the main body information is within the specified range.

If the result of the judgment by the main comparing section 22 is affirmative, the main transmission instructing section 23 instructs the main transmitting / receiving section 18A to display the main body information based on the ID corresponding to the user name. Is actually transmitted to the terminal karaoke device 3. Here, if the result of determination by the main comparison unit 22 is negative, the main transmission instruction unit 2
3 transmits a negative signal to the sub-center apparatus 1B side without transmitting the main body information to the terminal karaoke apparatus 3 to inform it. The main identification code inspection unit 28 confirms the ID returned when the transmission with the terminal karaoke device 3 is started as described above. By configuring the system in this way, the sub-center apparatus 1B can entrust transmission of the main body information to the main karaoke apparatus 1A when the main karaoke apparatus 3 supplies the main body information to the terminal karaoke apparatus 3. It is possible to check the format of body information.

The above operation will be further described with reference to the flow chart shown in FIG. First, when the sub-center device 1B wants to deliver predetermined body information to the terminal karaoke device 3, the main center device 1A in a connection waiting state is called (S21), and a line connection is established between the two (S2).
2). Next, the sub-center device 1B transmits the user name and the main body information to the main-center device 1A, so-called uploading is performed (S23). When the upload is completed here (S24), the main center device 1A determines whether or not the sent user name and body information are proper, and if they are proper, disconnects the line. (S2
5) If it is inappropriate, a negative signal is sent to the sub-center device 1
It returns to B (S40). By returning the negative signal, the sub-center apparatus 1B can recognize that the previous user name and main body information were invalid.

If the previous user name and body information are valid, the line is cut off, and then the main center apparatus 1A calls the terminal karaoke apparatus 3 in the connection waiting state (S26), Connect the line between the two (S2
7). Then, the main center apparatus 1A requests the terminal for the ID (S28), and in response, the terminal karaoke apparatus 3 returns its own ID (S29).
