[0002]
[Prior art]
In recent years, music distribution using a network has become a hot topic. In the music distribution service, a server for music distribution is provided on the network. When music distribution is used, a user terminal is connected to a music distribution server via a network. When purchasing a song, the user designates the purchased song and gives a download command. Thus, the music data is sent from the music distribution server to the user terminal and downloaded to the user terminal. At this time, the downloaded music is charged. Therefore, music content data is a purchase target.
[0003]
The major difference between the sales form of music at an existing record store and the sale of music on a network by a music distribution service is whether or not the substance of what is bought and sold is physically present.
[0004]
That is, a packaged CD (Compact Disc) album is sold at the record store, and the user purchases the packaged CD album at the record store.
[0005]
  In this way, users buy their favorite music at record stores, but what is sold at record stores isPackagingCD album. Therefore, what the user actually purchases is not the music itself, but a CD on which the music is recorded, a case for storing the CD, a jacket for decorating the case, a lyrics card enclosed in the case,Liner notesA packaged CD album consisting of
[0006]
The fact that an entity to be bought and sold is physically a unit in which the physical entity is bought and sold. Therefore, a packaged CD album is one sales unit, and CDs, jackets, liner notes, and lyrics cards constituting the CD album are not distributed individually.
[0007]
[Problems to be solved by the invention]
In contrast, in a music distribution service using a network, content data is provided to the user. That is, music data constituting one album, jacket data, liner notes and lyrics data are provided. The content data itself has no physical entity and can be distributed individually.
[0008]
  CD jackets are created in line with the CD album project, and there are many highly artistic ones. Also lyrics card,Liner notes, etc.Is highly valued for fans who support their music and artists. A CD album consists of a CD containing music, a case for storing the CD, a jacket for decorating the case, a lyrics card enclosed in the case,Liner notesPrice is included, jacket, lyrics card,Liner notesIf the CD is of high value, the price of the CD album will increase accordingly.
[0009]
Therefore, when music data, jacket data, liner notes, lyrics, and other data are distributed individually, it becomes possible for the user to purchase only what is necessary, which is inexpensive for the user. In addition, it becomes possible to purchase the data of the content that the user wants.
[0010]
However, data such as jacket data, liner notes, and lyrics are associated with music data constituting the album, and do not exist at all. Therefore, even when music data, jacket data, liner notes and lyrics data are distributed individually, when music data and its accompanying data are combined and when they are not combined Therefore, it is desirable to handle differently.
[0011]
For example, the purchase price will differ between purchasing music data and all data accompanying it such as jackets, liner notes, and lyrics, and purchasing only data such as jackets, liner notes, and lyrics. Can be considered. Also, in karaoke, etc., when paying per copy or paying per listen, it may be possible to change the billing amount depending on whether or not lyrics data is entered. It is done.
[0012]
  Therefore, the object of the present invention is to purchase content that matches the user's needs when purchasing content composed of main content data such as music data and additional content data such as jacket, liner notes, and lyrics data. Made it available for purchaseUser terminal and data purchase method, data distribution server and data distribution method,Data distributionsystemas well asData distributionMethod,AndData reproducing device andData playbackIt is to provide a method.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which the present invention is applied to a music distribution system.
[0019]
  In FIG. 1, the music distribution server 1 stores a large number of music data, jacket data, liner notes, lyrics, and other accompanying data. The music distribution server 1 allows the user to purchase from these music data.What you wantTheNetwork 3(For example, via the Internet).
[0020]
The user terminal 2 is a terminal operated by a user and can be realized by a personal computer. The user terminal 2 has a communication function and can be connected to the network 3. The connection of the user terminal 2 to the network 3 may use a telephone line, a CATV (Cable Televsion) network service, a mobile phone network service, or the like. Of course, a dedicated line may be used.
[0021]
When purchasing music data, the user terminal 2 is connected to the site of the music distribution server 1 via the network 3. When the user terminal 2 is connected to the site of the music distribution server 1 via the network 3, a music purchase web page is sent from the music distribution server 1 to the user terminal 2. A user operating the user terminal 2 performs an operation based on the screen of this web page when he wants to purchase music. Thereby, the music distribution server 1 sends the music data of the music that the user desires to purchase via the network 3 to the user terminal 2.
[0022]
The music distribution server 1 stores data such as jacket data, liner notes, and lyrics. A user operating the user terminal 2 performs an operation based on a web page sent from the music distribution server 1 in order to purchase additional content data accompanying these music. Thereby, the music distribution server 1 sends data such as jacket data, liner notes, lyrics, etc. that the user desires to purchase to the user terminal 2.
[0023]
FIG. 2 shows a format of data sent from the music distribution server 1 to the user terminal 2. As shown in FIG. 2, for each title, jacket image data A (for example, JPEG), liner notes data B (for example, TEXT), lyrics text data C (for example, TEXT), and a score Data D (for example, TEXT) and music data (musical piece) E (for example, MP3 or ATRAC3).
[0024]
FIG. 3 shows an example of a music distribution web page sent from the music distribution server 1. In FIG. 3, for example, when the title “blue sea” is designated, a purchase page as shown in FIG. 3 is sent.
[0025]
As a method of purchasing information for this title "Blue Sea",
(1) Purchase full data consisting of music (main content data) and all additional information (additional content data).
(2) Buy only music,
(3) Purchase all additional information only,
(4) Purchase additional information individually,
There is.
[0026]
As shown in FIG. 3, price displays 11a to 11l and purchase check displays 12a to 12g are provided according to each purchase method. The user checks the check displays 12a to 12g corresponding to the music and information he / she wants to purchase and clicks the purchase button 13. Thereby, data is sent from the music distribution server 1 to the user terminal 2, and this music data is stored in the storage device of the user terminal 2. At this time, charging is performed according to the price displays 11a to 11l.
[0027]
Here, in the case of full data, the purchase price is individually set according to the case of only music, the case of only additional information, and the combination thereof.
[0028]
For example, the price of only the music is 140 yen, the price of the jacket is 10 yen, the price of the liner notes is 10 yen, the price of the lyrics is 10 yen, the price of the score is 10 yen, and the total amount is
140 + 10 + 10 + 10 + 10 = 180 yen
It is. On the other hand, the price in the case of full data is 150 yen, and when the full data is purchased, the price of 30 yen is cheaper than purchasing individually.
[0029]
For users who want only music, it costs 180 yen to purchase full data individually, but it can be purchased for 140 yen, so you can get the music you want at a low price.
[0030]
The additional information is provided with a discounted price for a user who already owns the music. For example, if you don't own a song, the price of the jacket is 10 yen, the price of the liner notes is 10 yen, the price of the lyrics is 10 yen, and the price of the score is 10 yen, but you already own the song. The price of the jacket is 7 yen, the price of the liner notes is 7 yen, the price of the lyrics is 7 yen, and the price of the score is 7 yen. Thus, the user who already owns the music can purchase additional information with three discounts. For this purpose, it is necessary to prove that the music has already been purchased. To that end, it is conceivable to add a number to the purchased music or leave a cookie. Further, by leaving purchase information for each piece of content data and additional content data of a purchased music piece, copyright can be managed for each piece of content data.
[0031]
Thus, in this example, song data, jacket data, liner notes data, lyrics data, and score data can be purchased individually, and the price is set according to the combination. Is done. For example, if you purchase full data, you can get a discount, or if you have already purchased music data, you can get additional content data at a low price, and purchase data according to your needs. Will be able to.
