Abstract

PROBLEM TO BE SOLVED: To make it possible to transfer music data without accessing an external storage device such as a hard disk drive even when the same music is selected successively from plural terminal devices, and shorten the response time by providing a means which manages information stored in a buffer memory. SOLUTION: A music transfer management part 3 judges whether or not the same music as last transferred music is specified from notification information from a music information analysis part 4, and sends a transfer indication for the music data to a music data transfer part 6 when the same music as the last transferred music is specified. Further, when music different from the last transferred music is specified, a music data retrieval part 2 is instructed to read in the music data. Thus, the music transfer management part 3 manages music transferred to the buffer memory 5 and when the same music is specified successively from different user terminal devices 9a-9n, the music data are transferred to user terminal device memories by being read out of the external storage device 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music data transfer system, and more particularly to a music data transfer control system in a music viewer.

[0002]

2. Description of the Related Art Conventionally, in this type of music data transmission control system, in consideration of a repeat operation by a user, when the same music piece is designated from the same user terminal device,
The center device does not reread the music data from the external storage device that stores the music data, but reproduces the music data that has been transferred to the user terminal device. However, when the same song is selected among different user terminal devices, a method is adopted in which the song data is read again from the external storage device and the song data is sequentially transferred to the user terminal device.

Further, as a conventional technique of a file system for independently providing information having real time and continuity such as music and movies to a plurality of user terminals, for example, Japanese Unexamined Patent Publication No. Hei 4-
Japanese Patent No. 302039 discloses a temporary storage unit that temporarily stores a plurality of information in response to a request from a user terminal,
A search unit for searching whether or not the requested information is stored in the temporary storage unit, and the requested information when the requested information is stored in the temporary storage unit. Means for reading out, and when the requested information is not stored in the temporary storage unit, stores the information transferred from the external basic file unit in the temporary storage unit, and from the temporary storage unit to the user terminal. A file system including a means for providing desired information has been proposed. FIG. 3 shows the configuration of this conventional technique.

In the system of FIG. 3, the user terminal group 11,
A retrieval unit 12, a temporary storage unit 13 (for example, a hard disk group), a basic file unit 14 (information supply means having a function for transmitting information and a means for storing and storing information, for example, a compact disc reproducing apparatus), and a reading unit 15. It is composed of

The feature of this conventional system is that since information with a large number of requests is stored in the temporary storage unit 13, the request from the user terminal group 11 is searched by the search unit 12, and the information is stored in the temporary storage unit 13. If it is stored, it is read from the temporary storage unit 13 and transferred to the user terminal group 11. On the other hand, when there is no requested information in the temporary storage unit 13, it is read from the basic file unit 14,
The read information is stored in the temporary storage unit 13 and transferred to the user terminal group 11.

As described above, in this conventional method, the information in the temporary storage unit 13 is searched every time there is a request from the user terminal group 11, and even when there is information in the temporary storage unit 13, the hard disk device is searched. Is accessed, information is read, and information is transferred to the user terminal group 11.

[0007]

As described above,
In the above-described conventional transmission control method, since the music information selected for each user terminal device is managed, when the same music song is continuously specified from the same user terminal device, Although the music can be played back without reading the music data from the external storage device again, if the same music is continuously specified by different user terminal devices, the music data should be read from the external storage device successively. Therefore, there is a problem that it takes a long time from when the user selects a song on the terminal device until when the user listens to the song. Further, since the external storage device is sequentially accessed, there is a problem that the load on the center device increases.

Also in the system disclosed in the above-mentioned Japanese Patent Laid-Open No. 4-302039, when a plurality of user terminal devices request exactly the same music, the temporary accumulating unit is always accessed and information is stored. Must be read and transferred, causing similar problems.

Therefore, the present invention solves the above-mentioned problems of the prior art, and does not access an external storage device such as a hard disk device even when the same song is continuously selected from a plurality of terminal devices. It is an object of the present invention to provide a data transfer method that enables transfer of music data and shortens response time.

[0010]

In order to achieve the above object, the present invention provides a storage device for storing music data in advance, and a user terminal device for selecting music to be listened to by a user and listening to the specified music. And song information analysis means for analyzing song information input from the user terminal device and converting it into predetermined management information, and song data for reading song data from the storage means based on a signal from the song information analysis means. Search means, transfer control means for transferring the music data read by the music data searching means to the user terminal device, and the transfer destination user terminal when the transfer control means transfers the music data A terminal designating means for designating a device, a buffer storage device for writing music data transferred by the transfer control means, a music transfer management means for managing the music information transferred by the transfer control means, Providing music data transfer method characterized by comprising a user terminal device control means for performing management and control of the user terminal device.

According to the present invention having the above-described structure, since the means for managing the information stored in the buffer memory is provided, a plurality of different user terminal devices continuously request the same music piece. Even if this happens, the music data can be transferred from the buffer memory device to a plurality of user terminal devices so that the music data can be transferred without accessing the external storage device again. It was done.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. With reference to FIG. 1, song data for trial listening is stored in an external storage device 1. When the music information to be previewed is input from the user terminal device 9, the music data to be previewed is input to the music information analysis unit 4 via the user terminal device control unit 8.

The music information analysis unit 4 analyzes the inputted music information, converts it into predetermined internal management information, and notifies the music transfer management unit 3 of it.

On the basis of the notification information from the song information analysis unit 4, the song transfer management unit 3 judges whether or not it is the same as the previously transferred song, and if it is the same as the previously transferred song, the song data transfer The transfer instruction of the music data is issued to the section 6. If it is different from the music transferred last time, the music data searching unit 2 is instructed to read the music data.

The music data retrieval unit 2 reads music data from the external storage device 1 based on the information notified from the music transfer management unit 3, and notifies the music data transfer unit 6 of the music data. At this time, the song data transfer unit 6 receives the notification from the song data search unit 2
After designating the user terminal device 9 that transfers the music data to the terminal designating unit 7, the music data notified from the music data searching unit 2 is written in the buffer memory 5.

On the other hand, when the song data transfer unit 6 notifies the song data transfer unit 6 of a song data transfer instruction, the request is for the same song as the song transferred last time, and therefore the buffer memory 5 has already stored it. Stores song data. Therefore, the user terminal device 9 that transfers the music data to the terminal designating unit 7
After specifying, the music piece data stored in the buffer memory 5 is rewritten in the buffer memory 5.

The song data written in the buffer memory 5 is stored in the buffer memory 5 and, of the user terminal device memory 10 provided for each user terminal device in the user terminal device controller 8, , And is transferred to the user terminal device memory 10 designated by the terminal designation unit 7 (see FIG. 1).

The music data stored in the user terminal device memory 10 is reproduced as music in the user terminal device controller 8 and sent to the user terminal device 9.

The details of the operation of this embodiment will be described below.

FIG. 2 is a diagram showing the relationship between the buffer memory 5, the terminal designating unit 7, and the user terminal device control unit 8.

When the signal for designating the user terminal device 9 for transferring the song data is input from the song data transfer unit 6, the terminal designating unit 7 outputs a memory select signal, and the user terminal device control unit 8 is provided. Only the designated user terminal device memory 10 is writable. At this time, the other unspecified user terminal device memory 10 is in a data write prohibited state.

In this state, when the music data transfer unit 6 writes the music data to the buffer memory 5, the write data is transferred to both the buffer memory 5 and the user terminal device memory 10, and the user In the terminal control unit 8, the user terminal device memory 1 designated by the terminal designation unit 7
Song data is written only for 0. At this time, since the song data is also written in the buffer memory 5, when the song data in the buffer memory 5 is transferred to the user terminal device memory 10 again, the terminal designating unit 7 causes the user terminal device memory to be transferred. After designating 10, the music data can be written in the user terminal device memory 10 by retransferring the data in the buffer memory 5 to the buffer memory 5.

In the present embodiment having the above-described structure, the music transfer management unit 3 manages the music transferred to the buffer memory 5, so that the same music can be continuously reproduced from different user terminal devices 9. If specified, the song data can be transferred to the user terminal device memory 10 without reading the song data from the external storage device 1, so that the load on the external storage device 1 is reduced and the user terminal device is reduced. The response of 9 can be sped up.

[0025]

As described above, according to the present invention, by managing the information stored in the buffer memory, when the same music piece is continuously designated, the music piece data is again stored in the external storage device. Since the song data can be transferred to the user terminal device memory without reading out, it is not necessary to access the external storage device when the same song request is made from each user terminal device, Not only can the load on the external storage device and the center device be reduced, but when the same song is selected from a plurality of user terminal devices, the response of the second and subsequent user terminal devices can be made faster. effective.
