[Problems to be solved by the invention]
In a conventional online karaoke system, one karaoke center and karaoke performance terminals under its jurisdiction are generally installed in the same area. This shortens the communication distance between the karaoke center and the karaoke performance terminal, thereby reducing the communication cost. However, not all karaoke performance terminals are installed in the same city call area as the karaoke center. For this reason, there is a difference of two times or more in the call charge between when the karaoke data is distributed to the karaoke performance terminal in the city call area and when it is not. Karaoke performance terminals continue to increase year by year, and tend to be installed throughout the country. The communication cost for karaoke data distribution to such a karaoke performance terminal is enormous. In order to reduce communication costs, a karaoke center may be added to cover all local call areas where karaoke performance terminals are installed. However, enormous costs are required to install a karaoke center. Moreover, the karaoke center has only a relay function for karaoke data. For this reason, there is no added value other than the reduction of communication costs due to installation, and a significant cost reduction cannot be expected if costs for maintenance and inspection are calculated. Considering the communication cost between the host center and the karaoke center, increasing the number of karaoke centers unnecessarily may increase the cost.
[0004]
Therefore, an object of the present invention is to reduce the communication route for the toll-to-city call charge to the karaoke performance terminal without increasing the number of installation locations of the karaoke center, and to greatly reduce the communication cost for karaoke data distribution. It is to provide a karaoke system.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows the configuration of a communication karaoke system according to an embodiment of the present invention. The host center 2, the karaoke center 10, and the karaoke performance terminals 30a to 30c are connected to the telephone lines 50a and 50b, and the karaoke data is distributed from the host center 2 to the karaoke performance terminals 30a to 30c. is there. In the communication karaoke system according to the present invention, the distribution route of karaoke data is different from the conventional one. Of course, distribution of karaoke data from the karaoke center 10 to the karaoke performance terminal 30c in the same local call area 60a uses the local call telephone line 50a. However, karaoke data is first distributed to the karaoke performance terminal 30a designated as a relay station to the karaoke performance terminals 30a, 30b in charge of the karaoke center 10 and located in the long-distance call area. The relay station 30a stores the karaoke data in its own data storage unit, and then transfers the karaoke data to the karaoke performance terminal 30b in the same local call area 60b. The karaoke performance terminals 30a to 30c have the same internal configuration except for the role in the distribution of karaoke data. Next, functions and operations of the online karaoke system according to the present invention will be described.
[0009]
FIG. 2 shows a configuration diagram of the karaoke performance terminals 30a to 30c according to the present embodiment. The karaoke performance terminals 30a to 30c include a central control unit 31, a hard disk device 32, a modem 33, an audio playback unit 34, a display control unit 35, a speaker 36, a display 37, an operation control unit 38, and the like. The basic function of the karaoke performance terminals 30a to 30c is of course the reproduction of karaoke music. The operation is the same as that of a conventional karaoke performance terminal. The central control unit 31 controls the peripheral components and controls the karaoke performance terminal. Then, the designated karaoke music piece is output to the speaker 36 and the display 37 by synchronizing the karaoke accompaniment piece and the lyrics image.
[0010]
Furthermore, the karaoke performance terminals 30a to 30c according to the present invention also operate as the relay station 30a in karaoke data distribution. In this case, the transfer destination telephone number list is stored in the hard disk device 32. And the central control part 31 controls the modem 33, and calls the other karaoke performance terminal 30b of the same local call area 60b on the telephone number list one by one. When the line connection with the transfer destination karaoke performance terminal 30b is confirmed, the data to be transferred among the karaoke data stored in the hard disk device 32 is sent to the telephone line 50a to the transfer destination karaoke performance terminal 30b. Deliver karaoke data.
[0011]
FIGS. 3A and 3B are flowcharts for explaining an “opening procedure” for operating the karaoke performance terminal as the relay station 30a. FIG. 3A shows work at the karaoke center 10. When a karaoke performance terminal managed by the karaoke center 10 is newly installed or abolished or a telephone number is changed, a new telephone number list is sent from the host center 2 together with karaoke data distribution (101). Then, the telephone number list so far stored in the data storage unit is updated (102). Next, it distributes to the karaoke performance terminal 30c in the same local call area 60a and the karaoke performance terminal in the out-of-city call area (103, 104). Further, the karaoke performance terminals in the long-distance call area are classified according to the area code (105). An appropriate karaoke performance terminal is designated as the relay station 30a in the area 60b having the same area code (106). When the karaoke data is distributed to the karaoke performance terminals (30a, 30c), the specified relay station 30a is distributed with the notification of opening of the station and the transfer destination telephone number list attached to the karaoke data (107, 108). .
[0012]
FIG. 3B shows an operation at the karaoke performance terminal designated by the relay station 30a. When the karaoke performance terminal receives the designation of the relay station 30a, the karaoke performance terminal operates the function as the relay station (111 to 113). The telephone number list is stored in its own hard disk device 32, and the above-described operation for transferring karaoke data is performed (114 to 117). When the transfer is finished, the role as the relay station 30a is finished, and the telephone number list is deleted from the hard disk device 32 (118, 119).
[0013]
Instead of the local karaoke center 10 performing a task of designating the relay station 30a or creating a transfer destination telephone number list in the designated relay station 30a and sending it to the relay station, the central karaoke center is used. The host center 2 may do this. In this case, the data for the opening procedure is distributed to the relay station 30a via the karaoke center 10.
[0014]
Further, the designation of the relay station and the sending of the telephone number list are not limited to the distribution of karaoke data, but may be distributed as necessary at an appropriate time. In this case, the karaoke terminal designated as the relay station 30a stores the previous telephone number list until the next telephone number list is sent. Then, the memory is held until the telephone number list is updated or the relay station is closed.
[0015]
【The invention's effect】
According to the present invention, some karaoke performance terminals activate the karaoke data transfer function to transfer karaoke data to other karaoke performance terminals in the same local call area. For this reason, the distribution route of the karaoke data by the long distance call can be greatly reduced without adding a karaoke center. Therefore, karaoke data can be distributed to a large number of karaoke performance terminals with a minimum communication cost.
