TECHNICAL FIELD OF THE INVENTION

  In a communication karaoke system including a global server, a local server, and a karaoke terminal, a local server and a plurality of karaoke terminals are connected to a LAN laid in a karaoke store. And the global server which accumulate | stores and manages karaoke data about many karaoke music distributes karaoke data in a timely manner to the local server under the VPN using the Internet. The local server stores the karaoke data from the global server in its external storage.

  The karaoke terminal transfers the song identifier of the requested song received by the user input to the local server via the LAN. The local server returns karaoke data corresponding to the music identifier from the karaoke terminal to the karaoke terminal that has sent the identifier. The karaoke terminal reproduces the karaoke data and outputs an accompaniment music and lyrics image of the karaoke music.

  In the communication karaoke system having the above configuration, karaoke data is not stored in the karaoke terminal, so that if the local server breaks down, karaoke cannot be performed. Therefore, in addition to the main local server that is in operation, a spare local server is installed in a karaoke store. If the main local server fails, the spare local server is restored until the main local server is restored. To replace it.

  However, unlike a global server, a local server is installed at many karaoke stores throughout the country, and a spare local server is installed at each store at its expense. As a karaoke store, there is a considerable resistance to installing a spare local server that has a very low possibility of failure and is difficult to obtain cost effectiveness. Therefore, an object of the present invention is to provide a communication karaoke system that can reliably cope with a failure at low cost without providing a spare local server.

=== Network configuration ===
FIG. 1 is a network configuration diagram of a communication karaoke system in an embodiment of the present invention. Various server computers (11, 12) and a LAN 21 installed in a karaoke store 20 are connected to a VPN (Virtual Private Network) 6 using the Internet via a network communication device such as a router (15a to 15c) to establish a wide area intranet. Has been built.

  A management server 11 and a global server 12 are connected to the intranet as server computers directly controlled by a karaoke company, and a local server 13 and a karaoke terminal connected to the store LAN 21 as computers managed by each karaoke store 20 14 is connected.

  A plurality of global servers 12 installed in each region, such as prefectures, provide a large number of karaoke data, which are the origin of playback of accompaniment music of karaoke music, lyric images, and background video of lyrics, in a predetermined file format capable of streaming transfer. The music is stored and each karaoke data is identified and managed by the music identifier. Then, the karaoke data is periodically distributed to the local server 13 that is in charge of distribution. The management server 11 is prepared to deal with a failure of the local server 13, communicates with the karaoke terminal 14 individually, and monitors the recovery status of the failed local server 13.

  In the intranet, each computer (11-14) including the karaoke terminal 14 can be identified and managed by ID. As this ID, appropriate identification information such as an IP address or a MAC address can be adopted according to the communication protocol in the intranet. Of course, it is also possible to set a unique name (computer name) for each computer (11 to 14), associate the computer name with an IP address or MAC address, and use the computer name as an ID.

=== Backup function ===
The communication karaoke system 1 of the present embodiment is provided with a backup function that prevents the music playback on the karaoke terminal 14 from being paused even if the local server 13 breaks down without preparing an alternative local server 13 separately. And each computer (11-14) which comprises the communication karaoke system 1 is each mounted with a different program, and each runs the program currently mounted in itself, cooperating with another computer (11-14). Thus, the backup function of the communication karaoke system 1 as a whole is developed.

=== Basic operation ===
In FIG. 2, the communication procedure between each computer (11-14) in connection with the backup function in the communication karaoke system 1 was shown. The global server 12 periodically accesses the local server 13 to which karaoke data is distributed and distributes karaoke data such as new songs (s1). The local server 13 accumulates and manages the karaoke data distributed from the global server 12 in its own external storage (s2). The karaoke terminal 14 stores the ID (request destination server ID) of the computer that is the request destination of the music identifier received by the user input. When the local server 13 is operating normally, the request destination server ID is the ID of the local server 13 on the same LAN 21 as itself. When the karaoke terminal 14 sends the song identifier to the local server 13 and requests karaoke data of the requested song, the karaoke terminal 14 waits for a predetermined time (s3, s4).

  When the local server 13 in normal operation receives a music identifier from the karaoke terminal 14 on the same store LAN 21, the local server 13 performs streaming transfer of karaoke data corresponding to the music identifier to the karaoke terminal 14. The karaoke terminal 14 recognizes that the local server 13 is operating normally by receiving the karaoke data within a predetermined time, and processes the karaoke data that has been stream-transferred in parallel while buffering it as needed. Are reproduced and output to the speaker 23 and the display 24 accompanying the accompanying music and the moving image including the lyrics (s4 → s5, s6).

=== Failure notification processing, failure response processing, recovery monitoring processing ===
If the local server 13 is out of order, the karaoke terminal 14 times out without a response from the local server 13 even after waiting for a predetermined time after transmitting the music identifier. The karaoke terminal 14 recognizes the failure of the local server 13 with this timeout. When the karaoke terminal 14 recognizes the failure of the local server 13, the karaoke terminal 14 sends a failure notification including its own karaoke terminal ID and the requested server ID stored in the karaoke terminal 14 to the management computer 11 (s4 → s7).

  When receiving the failure notification from a certain karaoke terminal 14, the management computer 11 acquires and stores the karaoke terminal ID and the request destination server ID received from this terminal 14 (s8). Then, the failure notification is sent, and the ID of the predetermined global server 12 is returned as the new request destination server ID to the karaoke terminal 14 as the request destination of the karaoke data (s9), and the local corresponding to the stored request destination server ID is returned. With the server 13 as a monitoring target, the server 13 periodically communicates with the local server 13 to monitor whether it has recovered from a failure (s14, s15). In order to determine the global server ID to be returned to the karaoke terminal 14, a table in which the karaoke terminal ID or the local server ID is associated with the predetermined global server ID is prepared in the management server 11, and a failure notification is made. The global server ID corresponding to the karaoke terminal ID and local server ID included in the server may be returned. Alternatively, the management server 11 communicates with the global server 12, and, for example, the ID of the global server 12 having sufficient processing is assigned to the karaoke terminal according to the distribution schedule of karaoke data in the global server 12 or the distribution status of karaoke data at the present time. 14 may be returned.

  The karaoke terminal 14 replaces the new request destination server ID sent from the management server 11 with the stored request destination server ID (s10). Thereby, the karaoke terminal 14 requests karaoke data from the global server 12 (s11), the global server 12 returns the requested karaoke data to the karaoke terminal 14 (s12), and the karaoke terminal 14 reproduces and outputs this karaoke data. (S13).

=== Recovery handling process ===
When the management server 11 periodically communicates with the monitored local server 13 and recognizes that it has been restored, the management server 11 determines the local server 13 based on the karaoke terminal ID stored in association with the ID of the local server 13. The karaoke terminal 14 that has sent the failure notification as the monitoring origin is notified that the local server ID is the requested server ID, and is notified that the local server 13 has been restored (s14 to s16 → s17). The karaoke terminal 14 replaces the request destination server ID sent from the management server 11 with the request destination server ID corresponding to the stored global server 12 (s18). As a result, the karaoke terminal 14 requests karaoke data from the local server 13 on the same LAN 21 as that of the local server 13 in the same manner as before the local server 13 breaks down, and reproduces the karaoke data returned in response to the request. (S19 to s21).

=== Brotherhood karaoke terminal ===
In the karaoke store 20, there are a plurality of karaoke terminals 14, and when the local server 13 breaks down, each karaoke terminal 14 individually performs processing such as failure notification and replacement of the requested server ID. Therefore, one karaoke terminal 14 may perform processing related to failure notification and replacement of the requested server ID as a representative of the karaoke terminal 14 on the same LAN 21.

  Specifically, the karaoke terminal 14 recognizes the karaoke terminal 14 storing the same request destination server ID, such as the karaoke terminal 14 on the same LAN 21, as a sibling karaoke terminal, and communication is possible between the sibling karaoke terminals. Keep it. Then, the karaoke terminal 14 that first recognizes the failure of the local server 13 declares to the other sibling karaoke terminal that it is the representative karaoke terminal 14, and then sends a failure notification to the management server 11. When the ID of the global server 12 is sent from the management server 11, this global server ID is stored as a request destination server ID, and this global server ID is sent to other sibling karaoke terminals 14. Each sibling karaoke terminal 14 stores this global server ID as a requested server ID. Thereby, all of the companion karaoke terminals 14 are set to issue a karaoke data request to the global server 12.

  In addition, when the local server ID is sent from the management server 11 along with the recovery of the local server 13, the karaoke terminal 14 that has issued a failure notification as a representative stores the ID as a request destination server ID and the like. Distribute local server IDs to other karaoke karaoke terminals. Each sibling karaoke terminal 14 stores this local server ID as a request destination server ID, and is set to request karaoke data from the local server 13 as before the local server 13 breaks down.

  By providing the representative karaoke terminal 14 in this way, communication opportunities between the karaoke terminal 14 and the management server 11 can be minimized, communication traffic can be saved, and the processing load on the management server 11 can be reduced. Moreover, it is not necessary for each karaoke terminal 14 on the LAN 21 to confirm a failure of the local server 13, and the time required for the confirmation can be saved. And it can perform without delay from the reception of the request from the user to the reproduction processing of the karaoke data, so that no unnecessary waiting time is given to the user.

It is a block diagram of the communication karaoke system in the Example of this invention. It is a flowchart of the process in connection with the backup function in the said communication karaoke system.
