Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a BGM terminal device capable of determining a background music (BGM) performance song according to a user's preference.

[0002]

2. Description of the Related Art Conventionally, a cable broadcasting terminal device has been generally used as a device for playing BGM at restaurants and homes. Cable broadcasting consists of a number of channels that continue to play songs of specific genres such as hit songs, classical songs, and folk songs. The user can listen to a desired song by matching the reception channel of the cable broadcasting terminal device with the channel of the desired genre.

[0003]

However, in the above-mentioned cable broadcasting, the user can reflect his / her own preference only by selecting his / her favorite channel, and the schedule such as what song to play at what time and so on can be set. It was entirely up to the broadcasting station. Further, in order to change the BGM genre for each time period, the user had to switch the channel each time. Therefore, it is difficult to flow BGM according to the user's preference.

This invention is based on the user's schedule
It is an object of the present invention to provide a BGM terminal device capable of playing BGM according to the user's preference by playing M.

[0005]

SUMMARY OF THE INVENTION The present invention is a BG that downloads BGM performance data from a distribution center and performs the performance.
The M terminal device includes schedule generating means for generating a performance schedule, download means for temporarily downloading a plurality of BGM performance data corresponding to the performance schedule generated by the schedule generating means from the distribution center, and the downloading means. And a performance means for sequentially performing a plurality of BGM performance data downloaded by the means in accordance with the performance schedule.

According to the present invention, the BGM performance itself is not transmitted from the distribution center, but the BGM performance data for performing the BGM performance is downloaded from the distribution center. Further, the BGM performance data is not downloaded one by one, but a plurality of BGM performance data corresponding to the generated performance schedule is downloaded at a time. When the performance schedule for one day is generated, one day's worth of BGM performance data is downloaded at a time. After that, the BGM terminal device follows the above-mentioned performance schedule without communicating with the distribution center.
BGM is played sequentially using the GM performance data. As a result, the terminal device can determine the music to be played as BGM and the performance order thereof, and the distribution center also has a large number of BGMs.
Since only the BGM performance data is downloaded to the terminal device, any performance schedule can be supported.

If the BGM performance data is composed of MIDI data, it can be created with a data amount of about several tens of kB per song, so that even 100 songs of data can be downloaded in a few minutes.

Further, the schedule generating means may generate a performance schedule in which song names or song numbers are listed one by one, giving flexibility to a certain degree of music selection so that a particular genre, composer, etc. can be selected for each time period. You may generate the schedule which plays the music corresponding to classification information. Further, by using a keyword such as "bright song" or "light song" that expresses the impression of the song, it is possible to generate a schedule for playing a song with a particular impression for each time period.

FIG. 3 is a memory block diagram of the BGM terminal device 3. FIG. 7A is a diagram showing a schedule table set in the RAM 12, and FIG. 7B is a diagram showing a performance data file set in the download RAM 13. In FIG. 7A, a performance schedule is stored in the schedule table. The performance schedule includes date, time zone number (1 to 5), start time and end time of each time zone, and music selection data for selecting BGM to be played in each time zone. As the music selection data, one music may be designated by a music title, a music number, or the like, or attributes such as a genre and an announcement time may be designated. Details of the music selection data will be described later. Further, in this figure, the time zone is composed of five frames 1 to 5, but the number of time zones is not limited to this, and the start time and end time of each time zone are also limited to this. It is not something that will be done. If the download is executed as a back action, the BGM performance can be continued for 24 hours. Further, the performance schedule is not limited to one day, but may be a plurality of days such as several days or one week, and the same schedule may be repeatedly used for a plurality of days.

FIG. 5 is a flow chart showing the performance operation. First, the time zone pointer j is set to 1 (s1
0). Then, until the time reaches the start time of the time zone 1, s
Wait at 11. At the start time of time zone 1 (s1
1) The BGM performance data in this time zone is read and the performance is executed (s12). Area j of performance data file
Since a plurality of BGM performance data are stored in the performance order, the BGM performance is continued by reading the data in order. When it is determined that the time zone j has ended in s13, it is determined whether or not there is a next time zone (s14). In some cases, 1 is added to j and the process returns to s12.

FIG. 6 shows the structure of BGM performance data. B
The GM performance data is composed of extracted data and a data body. The data body consists of a plurality of part tracks and a DSP control track. Performance data of various musical instruments (timbres) such as a piano part, a drum part, and a strings part is written in each part track. DSP control data for controlling the DSP 19 of the BGM terminal device 3 is written in the DSP control track. The DSP 19 gives various effects such as echo reverb to the tone signal formed by the sound source 18, and the DSP control data controls the kind and degree of the effect given in synchronization with the performance of the BGM.

On the other hand, the extracted data is data representing the contents of the BGM performance data, and the BGM based on the music selection data.
Used to select performance data. The extracted data is the song name,
Data that directly identifies this song, such as the song number, data that represents the attributes of this song, such as the composer, genre, and release date, impression values (x1, x2, ..., x) that are the coordinate values that represent the impression of the song.
It consists of 7). Here, the impression value (x1, x2,
, X7) are the impression axes (coordinate axes) 1 shown in FIG. 7, respectively.
“Bright ← → dark”, impression axis 2 “light ← → calm”, impression axis 3 “modern ← → classical”, impression axis 4 “masculine ← → feminine”, impression axis 5 “hard” ← → Soft ”, impression axis 6“ Western style ← → Japanese style ”, impression axis 7“ Urban style ← → pastoral ”. ) To -1 (maximum right impression). With this impression value, this piece is plotted at one point in the multidimensional space defined by impression axes 1-7.

Now, the music selection data in the performance schedule and a method of selecting BGM performance data based on the music selection data will be described.

The following data is used as the music selection data. List of song names or song numbers Attribute data such as composer, genre (rock, easy listening, etc.), time of announcement (1970s, etc.), etc. Keywords that make up the impression axis (“bright”,
"Modern" etc.) and its degree (value in the range of +1 to -1) Keywords that do not form the impression axis ("Wedding-friendly", "Youth-friendly", "Night", etc.).

In the case of the music selection data in which the music names and the music numbers that directly specify the music are listed as described above, the distribution center 1 selects and downloads the BGM music data specified by the music selection data.

In the case of music selection data composed of attribute data as described above, BGM performance data having this attribute is retrieved from the file and downloaded. If the number of retrieved songs exceeds the length of the time period, it is randomly extracted from among them and downloaded. Alternatively, a plurality of attribute data may be designated as the music selection data, such as "rock (genre) from 1970 to 1975 (announcement time)", and cross search may be performed.

As described above, when a keyword forming the impression axis and the degree thereof are designated as the music selection data, that is, when an impression value of a certain impression axis is given, the point closer to the point of the impression value is selected. From the plotted BGM performance data, a predetermined number of songs (number of songs satisfying the time zone) are selected and downloaded. Since the impression values of all impression axes are not always given as the music selection data, the distance from the coordinate value of the music selection data may be calculated in a space of a dimension in which the impression axis not given the impression value is ignored.

As described above, when a keyword (free keyword) that does not form an impression axis is given as the music selection data, the keyword is interpreted to determine the impression value in the impression axis space, and the distance from this impression value point. A predetermined number of pieces of music are selected and downloaded in order from the BGM performance data plotted at points close to. For example, the free keyword "at night" is "slightly dark", "quite calm", "a little classic", "slightly feminine",
If it is interpreted as "neither hard nor soft", "neither Western nor Japanese", or "pretty urban", the impression value (x
1, x2, ..., x7) = (-0.4, -0.7, -0.3, -0.1, 0,
0, 0.7) is given. Then, in the coordinate space defined by the impression axis, this point (-0.4, -0.7, -0.3, -0.1, 0, 0, 0.7)
A predetermined number of music pieces are selected and downloaded in order from the BGM performance data given an impression value close to.

It should be noted that one selection data may be constructed by combining the above selection data. Also, when multiple songs are selected based on the selection data,
The performance order may be determined randomly by the distribution center 1 or the BGM terminal device 3, or may be determined by the user after being downloaded.

By writing various events such as wedding, funeral, Valentine's Day, and Christmas as attribute data in the extracted data, when the event is instructed as selection data, the BGM performance data suitable for the event is promptly selected. can do.

Further, when selecting a song based on a keyword such as, B is selected so as to match the instructed keyword.
You may make it process GM performance data. For example, when the keyword “dark” is designated as the music selection data, even if a song having a drum part track is selected, by not playing this drum part, a darker impression can be produced. In this case, the amount of data to be downloaded can be reduced by not downloading the drum part from the distribution center 1.

The interpretation of the selection data and the selection of the BGM performance data may be performed in the distribution center 1. The BGM terminal device 3 stores the extracted data of all the performance data, and the terminal device side performs this and distributes it. Only the music number may be uploaded to the center 1.

The BGM terminal device 3 has a built-in sound source 18 and electronically forms a musical tone signal. However, the BGM terminal device 3 is provided with a MIDI OUT terminal to automatically play an automatic musical instrument such as a piano. May be connected to play this automatic musical instrument with BGM performance data. Further, by adding the attribute "for automatic performance piano driving" to the BGM performance data provided with the track for driving the automatic performance piano, it is possible to play only the background music by the automatic performance piano during a certain time zone.

Although the BGM terminal device 3 stores the downloaded BGM performance data in the download RAM 13, it may be stored in the hard disk device. Further, although the performance schedule is input by the scheduler remote controller 5, the performance schedule input method is not limited to this. For example, a performance schedule created by another personal computer may be written in a PC card, and the performance schedule may be input by setting this PC card in the BGM terminal device 3.

In the above embodiment, the distribution center 1 is configured as a center that stores and stores only the BGM performance data dedicated to the BGM performance and distributes it to the BGM terminal device 3 only. The BGM system may be shared with the network of the online karaoke system currently in practical use. In this case, the center of the communication karaoke system also serves as the distribution center 1, and the center plays music data for karaoke and BG.
Both the BGM performance data for M performance are stored, the music data is downloaded to the communication karaoke device, and the BGM performance data is downloaded to the BGM terminal device.

Further, since the music data for karaoke performance has been accumulated over 10,000 songs in the past, this music data may be diverted to BGM performance data. The music data for karaoke performance is a lot of data such as a musical sound track (part track of BGM performance data) for driving the sound source 18 and a DSP control track, a lyrics display track for displaying lyrics, a voice track for generating back chorus and voice data. However, when it is used as BGM performance data, it is only necessary to download necessary data such as a musical tone track and a DSP control track. Then, the music data for karaoke performance is B
When playing as a GM, it is possible to perform like a BGM by increasing the volume of a melody track that is not played during karaoke or played at a low volume.

[0037]

As described above, according to the present invention, the BGM performance data is collectively downloaded from the distribution center and then sequentially played on the terminal device side, so that the performance uniquely generated by the terminal device is performed. BGM can be played based on the program, and BGM performance that suits the user's taste is possible.
