Description

  The present invention relates to a karaoke system for playing karaoke music on a karaoke terminal having a simple configuration and a karaoke program provided in a portable terminal.

  In recent years, in an online karaoke system for business use, an online karaoke business operator has produced a large number of karaoke music data (MIDI data (“MIDI” is a registered trademark, and will not be described below)). Installed karaoke terminals are installed in karaoke rooms, karaoke snacks, etc., and newly created karaoke music data is regularly distributed from distribution servers to each karaoke terminal and stored. . Each karaoke terminal has a MIDI sound source and a sequencer function, and generates music based on the MIDI data of the music requested by the user. Such a karaoke terminal has a simple configuration for cost reduction. Is desired.

  Conventionally, as a basic karaoke terminal, many technologies have been disclosed regarding the configuration and associated services of a commercial communication karaoke system in which contents such as lyrics, background video display, singing scoring, etc. synchronized with karaoke performance are provided as associated services. ing. For example, Patent Document 1 discloses a karaoke distribution system that includes a server, a mobile phone, and a karaoke terminal (a device having at least a playback device such as a MIDI sound source, an amplifier, and a speaker) that are communicably connected.

  In the karaoke distribution system disclosed in Patent Document 1, a user's mobile phone receives MIDI data from a server using a mobile phone communication network and a telecommunication network, and the MIDI data is transmitted to the mobile phone via short-range wireless communication. It is described as a configuration in which an audio signal is generated by a playback device such as a MIDI sound source based on MIDI data transmitted from a telephone to a karaoke terminal and received as karaoke music from a speaker.

  That is, in a karaoke terminal installed in a karaoke room or the like, karaoke song data of 200,000 or more songs is stored together with lyrics display data, singing scoring reference data, etc. regardless of whether the user sings or not. In addition, the storage cost and communication cost when viewed from the whole system are redundant and enormous. For this reason, if it is set as the structure which applies the technique disclosed by patent document 1, memorize | stores karaoke music data only in a server, and transmits to a karaoke terminal via a user's portable terminal for every karaoke performance, It is no longer necessary to store a large amount of karaoke music data on the karaoke terminal side, and the redundancy of storage cost and communication cost can be reduced.

  However, it is necessary to provide a MIDI sound source and sequencer function for generating musical sound (audio data) from MIDI data for each karaoke terminal, which complicates the structure of the karaoke terminal and greatly increases the cost. This is reflected in the usage fee paid by the user of the karaoke room. Therefore, for example, the server does not store MIDI data as karaoke music data, but stores audio data in MP3 format or the like like an existing music distributor's server, and transmits this audio data to the portable terminal. However, when audio data is used as karaoke music data, there is a major drawback in that sound quality deterioration due to tempo change or key change is conspicuous compared to MIDI data which is performance information.

  In karaoke singing, tempo change and key change are indispensable requirements for karaoke performance and must be specified for each user, and tempo / key change in MIDI data can be set at the stage of performance information. There is almost no load, and the generated audio data does not deteriorate, but changing the tempo / key in the audio data requires a complicated and heavy sound processing technology, and even if advanced technology is used, the sound quality is not deteriorated. There is an inevitable problem. Further, although the capacity of a large-capacity HDD is low, there is a problem that the capacity of audio data is much larger than that of MIDI data of the same music piece. Therefore, storing a large amount of audio data in the server should be avoided.

  On the other hand, MIDI data is produced while optimizing so that the performance and features of the MIDI sound source to be used are fully extracted, and the hardware of the MIDI sound source is generated so that higher-quality audio data can be generated. When trying to renew software, the compatibility of old and new MIDI sound sources is always an issue. In other words, MIDI data created specifically for the old MIDI sound source does not always bring out the performance and features of the new MIDI sound source, but in most cases it can only provide audio data that is much more unnatural than the old sound source. In the conventional communication karaoke system for business use, both the old and new MIDI sound sources must be mounted on the karaoke terminal. In this case, there is a problem that the cost of the karaoke terminal further increases.

  In the portable terminal 15, the audio music data acquisition program 86 adds each audio music data acquired from the server 11 to the music ID and stores it as the audio music data 78 in the storage unit 75 (S13). Then, the reserved music list creation application software 76 is terminated.

  Next, FIG. 6 shows a flowchart relating to music performance at the karaoke terminal. For example, when a user enters a karaoke room, the karaoke terminal 12 in the karaoke room becomes available by performing a check-in procedure at the reception.

  The user starts up the reserved music list creation application software 76 of the portable terminal 15 (S21), and makes an audio music data transfer request to the karaoke terminal 12 (S22). In the karaoke terminal 12, a data transfer request is received via the transmission / reception unit 58, and the audio music data acquisition means 59 makes an authentication request (S23) to the portable terminal 15 by the authentication means 59A. The portable terminal 15 receives the authentication result from the karaoke terminal 12 by outputting the authentication data (for example, serial number) to the karaoke terminal 12 by the authentication program 88 (S24).

  If the authentication result is “NG” (S25), S23 and S24 are repeated. If the authentication result is “OK” (S25), the karaoke terminal transfer program 87 reads the reserved music list 77 stored in the storage unit 75, and audio music data based on the music ID in the reserved music list 77 ( Audio data, lyrics data, reference data) 78 is read out and transferred to the karaoke terminal 12 together with the reserved music list 77 (S26).

  In this way, by performing mutual authentication processing between the mobile terminal 15 (reserved music list creation application software 76) and the karaoke terminal 12, the audio music data and the like stored in the mobile terminal 12 can be stored in the dark. It is possible to prevent an act of outputting to a device or transferring data acquired without following a regular procedure to the karaoke terminal 12.

  In the karaoke terminal 12, the audio music data acquisition means 59 temporarily stores the reserved music list 61 in the RAM 53 and also temporarily stores it as audio music data (audio data 62 A, lyrics data 62 B, reference data 62 C) 62. (S27).

  The user does not create the reserved music list 77 in advance as described above on the portable terminal 15, but after checking in the karaoke room, the reserved music list creating program 85 of the reserved music list creating application software 76 is used. To select a song to be sung from the audio song data 78 stored in the storage unit 75 that has already been downloaded to the mobile terminal 15 to create a reserved song list 77, and to the karaoke terminal 12 by the karaoke terminal transfer program 87. It may be transferred. After the transfer, the reserved music list creation application software 76 is terminated.

  Then, the karaoke terminal 12 sequentially reproduces the music according to the reserved music list 61 stored in the RAM 53 (S28). That is, in accordance with the reserved music list 61, the audio music data 62 is read based on the music ID, of which the audio data 62A is output to the playback means 55 for performance, and the lyrics data 62B is output to the lyrics display control means 60 for video. Displayed on the display unit 42 via the display control means 54, the reference data 62C is output to the scoring means 57, and the audio signal input from the microphone 44 via the audio signal input means 56 is compared with the reference data, thereby scoring. Is done.

  When the karaoke singing by the user ends, for example, when the user performs a checkout procedure at the reception, the reserved music list 61 and the audio music stored in the RAM 53 before the karaoke terminal 12 is disabled. Data 62 is to be erased (S29).

  Next, in FIG. 7, the flowchart of other embodiment regarding the music performance in a karaoke terminal is shown. This embodiment is a case where a plurality of users (a plurality of portable terminals 12) use the karaoke terminal 12, and the audio music data acquisition means 59 of the karaoke terminal 12 includes a list integration means (not shown). . Here, when the reserved music list and the audio music data are transferred from each mobile terminal 15 to the karaoke terminal 12, authentication processing is performed on each mobile terminal 15, but is omitted here.

  In FIG. 7, first, when each user A, B, C enters the karaoke room, for example, a check-in procedure is performed at the reception so that the karaoke terminal 12 in the karaoke room can be used by a plurality of users. It becomes. In other words, it is possible to accept music reservations from multiple users.

  Each user starts up the reserved music list creation application software 76 of each portable terminal 15 (S31). Therefore, the karaoke terminal transfer program 87 of the portable terminal A reads the reserved music list a (77) stored in the storage unit 75, and audio music data (audio data, lyrics data) based on the music ID in the reserved music list a. , Reference data) 78 is read out and transferred to the karaoke terminal 12 together with the reserved music list a (S32). In the karaoke terminal 12, the audio music data acquisition means 59 holds the reserved music list a and temporarily stores it as audio music data (audio data 62A, lyrics data 62B, reference data 62C) 62 in the RAM 53 (S33).

  Subsequently, the karaoke terminal transfer program 87 of the portable terminal B reads the reserved song list b (77) stored in the storage unit 75, and audio song data (audio data, lyrics) based on the song ID in the reserved song list b. Data, reference data) 78 is read out and transferred to the karaoke terminal 12 together with the reserved music list b (S34). In the karaoke terminal 12, the audio music data acquisition means 59 holds the reserved music list b, and temporarily stores it in the RAM 53 as audio music data (audio data 62A, lyrics data 62B, reference data 62C) 62 (S35).

  Subsequently, the karaoke terminal transfer program 87 of the portable terminal C reads the reserved song list c (77) stored in the storage unit 75, and audio song data (audio data, lyrics) based on the song ID in the reserved song list c. Data, reference data) 78 is read out and transferred to the karaoke terminal 12 together with the reserved music list c (S36). In the karaoke terminal 12, the audio music data acquisition means 59 holds the reserved music list c and temporarily stores it as audio music data (audio data 62A, lyrics data 62B, reference data 62C) 62 in the RAM 53 (S37). Then, in each portable terminal 15, the reserved music list creation application software 76 is terminated after the reserved music list and the audio music data are transferred.

  Accordingly, the audio music data acquisition means 59 of the karaoke terminal 12 creates a reserved music list by integrating the reserved music lists a, b, and c held therein, and stores them in the RAM 53 as the integrated reserved music list 61 (S38). The subsequent reproduction is the same as that after S29 in FIG. Thereby, a group user can enjoy karaoke singing. When creating the integrated reserved song list 61 in the audio song data acquisition means 59, if there are a plurality of the same song IDs with the same tempo / key specified, for example, the one transferred first is left in the list. Others may be deleted. As a result, it is possible to prevent the same music piece from being played many times and to use the karaoke room effectively in a limited time.

  Next, FIG. 8 shows a partial block diagram of another embodiment relating to music provision in the server, and FIG. 9 shows a flowchart relating to music provision in FIG. In this embodiment, karaoke song data and reference data are periodically added to the song DB 30 and the reference DB 31 included in the server 11.

  8, the music performance data conversion means 25 includes a plurality of conversion units, for example, a first conversion unit 25A, a second conversion unit 25B,. The first conversion unit 25A, the second conversion unit 25B, and the like have an optimal conversion function according to the creation time of the music performance data (MIDI data) of the music (music ID) to be added.
