Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a karaoke terminal for playing a karaoke music by driving a digital sound source, and a mechanism including a database connected to the karaoke terminal through a public line. And a mechanism for efficiently storing the information in a karaoke terminal.

[Conventional technology]

Recently, karaoke music has spread widely to ordinary households, but all of them are independent devices, and use karaoke music stored on these media such as audio tapes or optical discs recorded with PCM. It is a structure to do. However, with such a structure, if the recording medium does not contain more than a dozen songs per unit, the efficiency is low and there is also a storage space, so even if a new song is provided, it is not one song at a time. For example, it is currently performed only after a certain amount such as once a month. However, this cannot immediately respond to the user's request.

Therefore, in order to solve the current inconvenience, the applicant has conventionally developed a technology for converting karaoke music into digital information, storing the digital information in a database of a host computer, and downloading the digital information to individual karaoke terminals via a public line. ing. As a result, when a user of the karaoke terminal receives a new song, the user can download the song and use it immediately.

[Problems to be solved by the invention]

By the way, the transmission method that the applicant has been trying to introduce in the past is that the user of the karaoke terminal accesses the host computer by operating a keyboard or the like when desired, and plays a new song or a song that is not stored in the storage device of the terminal. It was meant to be downloaded.

However, in general, the use of karaoke terminals is concentrated at a specific time, and especially for business use, most of the night is spent for reproduction for singing, so requesting download during this time will reduce the usage rate. Is not preferred. On the other hand, use during the day is small, so if you access during this time, there is no inconvenience as described above,
With such a configuration, a person must operate a keyboard or the like each time, and it is not applied to business use in which the person is unattended during the day.

SUMMARY OF THE INVENTION The present invention is intended to solve such a disadvantage, and it is an object of the present invention to provide a device that can automatically provide new songs during the daytime when the utilization rate of a karaoke terminal is low and can store the new songs in a storage device of the karaoke terminal. Aim.

[Means for solving the problem]

The present invention is directed to a karaoke apparatus including a host computer (1) and a karaoke terminal, wherein the host computer (1) cyclically outputs karaoke data having a song number header and performs karaoke. The terminal has a main storage device (9), a receiving means (6), a digital sound source (8), a switching means (12), and two receiving memories (1).
1) A karaoke apparatus comprising control means (7),
The main memory (9) receives the karaoke data from the host computer (1) and outputs it to the switching means (12), the digital sound source (8) reproduces and outputs the karaoke data, and the switching means (12) receives the input. Alternately in karaoke data units
The reception memory (11) temporarily stores the karaoke data, and the control means (7) stores the karaoke data stored in the reception memory (11) and the main storage device (9).
Means for comparing the song number header of the karaoke data stored in the main memory (9) and storing the karaoke data in the reception memory (11) in the main memory (9) when there is no karaoke data to be verified in the main memory (9). It was decided to use it.

[Action]

The host computer has a function of, for example, transmitting a new song as a data string for a plurality of songs serially and cyclically at regular intervals. The receiving memory functions as a kind of buffer for storing data in the main storage device, and temporarily stores the data by switching for each unit data. Then, the music number of the data is compared with the music number of the data stored in the main storage device, and only the data not stored in the main storage device is saved. On the other hand, the reception memory is emptied after the completion of the collation in order to fulfill the function of a buffer, and is discarded if it is already accumulated as a result of the collation to prepare for the next reception.

〔Example〕

An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a host computer, which is a database in which a large number of karaoke music are formed by digital signals, respectively. 2 is a public line including an ordinary telephone line, and 3 is a host computer 1 via the public line 2.
And a karaoke terminal connected to it. In the present embodiment, the karaoke terminal 3 and the host computer 1 are connected not by a dedicated line but by a general telephone line, and have a structure having a so-called off-talk function. Here, the off-talk function means that when the subscriber telephone is not used, information is transmitted in one way from the telephone office, and this is connected to the karaoke terminal side to transmit data. It means a known configuration that performs switching by voltage change and can be used as a normal telephone line. A switching circuit 4 for achieving this function is connected to a telephone 5 on the one hand, and to a modem 6 for converting an analog transmission wave into a digital signal on the other hand. Reference numeral 7 denotes a CPU for controlling the entire karaoke terminal 3 and processing digital signals. Reference numeral 8 denotes a digital sound source driven by the above-mentioned digital signals. Reference numeral 9 denotes a capacity capable of storing a large number of karaoke music. Main storage device, actually MO disk (magnetic recording type optical disk)
Is used. Reference numeral 10 denotes an interface for connecting peripheral devices such as the CPU 7 and the digital sound source 8. Reference numerals 11a and 11b denote reception memories functioning as buffers for transmitted digital signals. The unit data handled is one karaoke music piece. Reference numeral 12 denotes a switch for switching between the reception memories 11a and 11b for each piece of music.
The switching of the switch 12 and the saving / loading of the reception memories 11a and 11b are all controlled by the CPU 7.

With such a device, karaoke music is sequentially stored in the main storage device.
A song number header is added for each song unit data, for example, 5
An example of data is composed of music pieces.

Next, the main storage device 9 for storing new music data and the like in the above-described configuration.
The procedure for saving data not stored in the storage device will be described. It is assumed that an appropriate quantity of karaoke music is stored in the main storage device 9 in advance. The host computer 1 constantly transmits a data string composed of about five songs cyclically to a subscriber telephone. At the karaoke terminal 3 on the receiving side, these data strings are serially transmitted to the modem 6 by the off-talk function. Karaoke terminal 3
On the side, these data strings are identified by the music number header, and are temporarily stored in the reception memory 11a or 11b as a buffer for each unit data. The CPU 7 analyzes the music number header and accesses the main storage device 9, and if the data is not stored in the main storage device 9, writes this data together with the music number header. On the other hand, if the data has already been stored, the data is discarded as it is, and the memory is emptied to wait for the reception of the next music. The CPU 7 controls the switch 12 to distribute data to the reception memories 11a and 11b for each unit data. If there is only one reception memory, it is possible to perform the function of storing new music, but if a plurality of planes are set as in this embodiment, high-speed processing can be performed.

If the data transmitted in this way is not stored, it is reliably stored in the main storage device.
As a premise, known error processing is performed by the modem 6. However, if the error cannot be resolved, the terminal transmits a retransmission request signal in general communication, thereby causing the corresponding data to be retransmitted. However, in this embodiment, since the data string is transmitted cyclically, there is no need to retransmit the data corresponding to the error. Then, it is sufficient to store error-free data at the next reception opportunity.

On the other hand, when the receiver of the telephone 5 is picked up or a call is received from another telephone, the switching is switched to the general telephone function by the switching circuit 4, and is switched to the function of the karaoke terminal again at the end of the telephone. Even in this case, since the data string is cyclically transmitted, there is no fatal effect on the data storage function.

〔The invention's effect〕

In the present invention, as described above, the data sequence is cyclically transmitted from the host computer and is received by the karaoke terminal. In this case, the data sequence is mainly performed via a plurality of reception memories provided in parallel. Since the data is stored in the storage device, there is no possibility of storing redundant data redundantly. Further, since the data is transmitted cyclically, even if an error occurs in the received data, the data can be captured at the next opportunity, and accurate data can be reliably stored.

Furthermore, since data transmission is performed on one way, it is possible to omit the operation of manually operating the keyboard and the like each time, so that data can be automatically accumulated during the free time in daytime, and efficiency can be improved. It became a device that can be used effectively as a good karaoke terminal.
