[4. Explanation of post data creation process of viewing karaoke device]
Next, post data acquisition processing executed by the karaoke apparatus 10 as the viewing side karaoke apparatus will be described with reference to the flowchart of FIG.

This process is repeatedly executed independently of other processes when the karaoke apparatus 10 is powered on.
First, in S305, user information related to the login user is acquired. Specifically, it waits until the user (viewer) inputs a user name to the operation unit 14, and when the user name is input, the remote control terminal 20 is inquired whether the viewer is logged in, When the user is logged in, the user information related to the viewer is requested to the remote control terminal 20 and the user information transmitted from the remote control terminal 20 is stored in the HDD 16.

  In subsequent S325, the additional information of the posted data received in S320 is displayed on the display unit 11 together with the posted data list. The additional information includes user information regarding the viewer, comments by the viewer, and evaluation information.

  In the subsequent S330, the post data desired by the viewer is requested. Specifically, the input of selection of post data to the operation unit 14 by the viewer is accepted, and the center 30 is requested to transmit the selected post data.

  In subsequent S335, post data desired by the viewer is acquired. Specifically, when the post data requested in S335 is transmitted from the center 30, the post data is received and stored in the HDD 16.

  In subsequent S340, the music reproducing unit 13 reproduces the music data corresponding to the posted data, and the listening data corresponding to the listening part of the performance part selected by the viewer in the acquired posted data is stored in the music. The music reproduction unit 13 reproduces the data while synchronizing with the data.

Since it has already been described that each performance part of the music data is set in advance, a detailed description thereof will be omitted here.
In addition, “synchronized” means that the selected part name, tempo value, and time lapse information are extracted from the recorded data of the posted data, and the time lapse information and listening time are recorded on the recording data side. It means that only the same section is reproduced by comparing with the section. At that time, on the music data side, the MIDI part of the selected performance part name is minus-one, and only the section of the same time lapse information as the recording data is reproduced with the tempo value at the time of recording.

  For example, when a plurality of sections are set for one piece of music data (see FIG. 2, for example, part A has three sections), the post data has the next section immediately after the end of the playback of one section. The time lapse information that is the playback start time of is specified. The posted data starts to be played from that time, and the music data is played back from the start time of the same section, and the playback of the posted data and the musical sound data in the same section is the same playback start and end timing. Continue in sequence until is finished.

  In addition, as described above, the listening sections may be sequentially jumped while being joined, and the listening sections may be joined and played back, or instead of jumping the time between the start and end of the playback of the posted data, the listening section Only the other playback and output may be muted until the playback timing reaches the next listening section.

  Therefore, in the listening section, the progress of the music data and the progress of the recording data coincide, and the music data has a track (part) of the recording data minus, so the MIDI part played by the contributor is There is no overlap between the performance of the posted data and the MID part (track) of the musical sound data that is not reproduced and reproduced by the music reproducing unit 13. Therefore, it becomes easier for the viewer to determine whether or not to purchase post data in the listening section.

In subsequent S345, it is determined whether or not post data is to be purchased. Specifically, an input instructing whether or not to purchase post data for the operation unit 14 by the viewer is accepted.
When the posting data is not purchased (S345: NO), it is determined whether or not the posting data is selected again from the list based on the input to the operation unit 14 by the viewer (S350), and the posting data is not selected again. (S350: NO), this process is terminated, and when posting data is selected again (S350: YES), the process proceeds to S325.

On the other hand, when purchasing contribution data (S345: YES), it transfers to S355.
In S355, billing processing is executed. Since the charging process follows a known technique, a detailed description thereof will be omitted here.

  In subsequent S360, the selected post data is purchased. Since the purchase process follows a known technique, a detailed description thereof is omitted here. This makes it possible to view all sections of all parts of the selected post data.

  In subsequent S365, the music reproducing unit 13 reproduces the music data corresponding to the purchased post data, and the music reproducing unit 13 synchronizes all the sections of all the performance parts of the purchased post data with the music data. Let it play.

  In subsequent S370, it is determined whether or not to evaluate the purchased post data. Specifically, an input for instructing whether or not to evaluate post data for the operation unit 14 by the viewer is accepted. When the purchased post data is not evaluated (S370: NO), this process ends. On the other hand, when the purchased post data is evaluated (S370: YES), the process proceeds to S375.

In S375, an input of a comment and a score by the user is received as evaluation information for the operation unit 14 by the viewer.
In subsequent S380, it is determined by referring to the evaluation history by the viewer whether or not the viewer has made the above evaluation on the same post data in the past.

  If the viewer has evaluated the same post data in the past (S380: YES), whether or not to overwrite the evaluation information based on the input to the operation unit 14 by the viewer. Judgment is made (S385). If the evaluation information is not overwritten (S385: NO), this process is terminated as it is. On the other hand, when the evaluation information is overwritten (S385: YES), the input evaluation information is added to the additional information and uploaded to the center 30 (S390), and this process is terminated.

  Further, even when the viewer has not made the above evaluation on the same post data in the past (S380: NO), the input evaluation information is added to the additional information and uploaded to the center 30 ( S390), the process is terminated.

[3. Effects of the embodiment]
(1) Thus, according to the karaoke network system 1 of this embodiment, there exist the following effects. That is, the music data is MIDI data composed of one or more performance parts, and a listening place is preset for each performance part. The karaoke device on the posting side creates posted data from the performance sound played by the user (poster) in synchronization with the MIDI data and uploads it to the center. On the other hand, the viewing-side karaoke apparatus acquires post data desired by other users (viewers) from the center, and reproduces only the listening place in the acquired post data. The viewer can play back all sections of all parts of the posted data after purchasing the posted data.

  As a result, viewers who want to view the posted data are first asked to view the listening place data corresponding to the listening place set in advance in the music data in the posted data. Therefore, the viewer can easily judge whether the posted data created from the singing signal or the performance signal input by the poster during the karaoke performance is good or bad.

  And the contributor can have a viewer appropriately evaluate the quality of the singing signal or performance signal input during his karaoke performance. Further, it is possible to prevent the viewer from duplicating all of the posted data by a malicious viewer at the first viewing time. Furthermore, after purchase, the viewer can view all the posted data.
