Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an invention for providing various services to consumers having a special receiver for data broadcasting by distributing content data using data broadcasting.

[0002]

2. Description of the Related Art In recent years, music data distribution services for providing music data such as popular music to general consumers by utilizing rapidly developing Internet technology are becoming widespread. By using this distribution service, a general consumer can download desired music data using a personal computer at home. For this reason, music CDs must be purchased
There is no need to buy, which is very convenient. Also,
Since the cost of producing and distributing CDs can be reduced, it is possible to set a low selling price for music data.

[0003] In the distribution service using the Internet, however, music sales fees can be set at a low price as described above, but communication fees (telephone line usage fees, provider contract fees, etc.) are required.

On the other hand, recently, music distribution services using digital data broadcasting have been studied. This digital data broadcasting is more suitable as a means for distributing music data because it is more resistant to noise and fading than conventional analog broadcasting and can transmit high-quality signals. Further, compared to the case of using the Internet, a communication fee is unnecessary, so that a consumer can obtain music data at a lower cost. Furthermore, if digital data broadcasting is used, the data transmission rate is 1 Mbps or more, so that when compared with a data transmission rate of 64 Kbps or the like when an individual uses the Internet with a personal computer (1 M = 1000 K), a short time is required. There is also an advantage that a large amount of data can be received.

[0005] Japanese Patent Application Laid-Open No. 2000-36184 discloses a method of providing music data distribution services to general consumers using such digital data broadcasting. Therefore, this method will be briefly described below with reference to FIG. FIG. 10 shows an example of data transmitted from a broadcasting station via a satellite, and each data shown in this figure is actually time-division multiplexed.

[0006] As shown in FIG.
The interval between the two is one event, and the next event from time t2. An event is a unit for changing the lineup of music, and is usually in units of 30 minutes or 1 hour. For example, 20 of the top 20 of the latest hit songs
It is conceivable that the 11th to 11th places are broadcasted in an earlier event, and the 10th to 1st places are broadcasted in a later event. This event is a unit of encryption.

[0007] In the event from the time t1 to the time t2, a music program (A1) having a predetermined content is broadcast as a normal moving picture program broadcast. In the event starting from time t2, a music program (A
2) is being broadcast. This normal music program (A1, A
2)) are moving images and audio.

[0008] For example, ten audio channels CH1 to CH10 are prepared.
At this time, each audio channel CH1, CH2, C
In H3,... CH10, the same music data is repeatedly transmitted during one event. That is, in the event from time t1 to time t2, the music data (B1) is repeatedly transmitted on the audio channel CH1, and the music data (C) is transmitted on the audio channel CH2.
1) is repeatedly transmitted, and thereafter, similarly, the music data (K1) is repeatedly transmitted on the audio channel CH10. In the event starting from the time t2, the music data (B2) is repeatedly transmitted on the audio channel CH1, the music data (C2) is repeatedly transmitted on the audio channel CH2, and thereafter, similarly, the music data (K2) is transmitted on the audio channel CH10. ) Is sent repeatedly.

[0009] Further, as a billing contract, a flat system in which a predetermined fee is paid every predetermined period, and a P system in which a fee is paid according to the content every time the content is viewed and listened.
There is a PV system. The main music program (A1) is charged in a flat manner, and the downloadable music data (B1, C1,... K1) is charged.
Charging is performed by the PPV method. In the PPV method, scrambling is performed in units of one event.
In the case of music data, the same music data is repeatedly transmitted multiple times within one event.

[0010] In the system using digital data broadcasting as described above, a general consumer may use a music program (A).
1) and the GUI (Graph) transmitted at the same time
By performing a necessary operation while viewing an image based on the H.I. User Interface (data), it is possible to view an information page for each song and to audition each song. Further, when a consumer wants to purchase a song that he / she has listened to, the user performs necessary operations while viewing the GUI image to download music data of the desired song and store it in a storage device such as an MD (Mini Disc). can do. The GUI data is data for forming a screen of a list page of music to be distributed and an information page of each music, and EPG (Electric).
This is data for forming an image for Program Guide). EPG is a program table by data broadcasting.

If the consumer cannot listen to the music program for reasons such as going out, the user can reserve the download of the music data in advance. When making a reservation, necessary operations are performed while viewing the GUI image. Thereby, at the reserved time, the music data of the desired music is automatically downloaded and stored in the storage device.

[0012]

However, in the above-described system using the conventional digital data broadcasting, if the music program (A1) is being broadcasted,
Simultaneously multiplexed and transmitted music data (B1, C
1,... K1), there is an advantage that the music can be previewed. However, when a reservation for download is made for reasons such as going out, there is a demerit that a preview cannot be performed due to multiplexing.

In a conventional system using digital data broadcasting, music data (B1, C1,... K1) cannot be downloaded until the date and time when the music program (A1) is broadcast. Therefore, the songs you want to listen to are 2
If two music data transmission intervals are open, such as when one is transmitted in the morning and the other is transmitted in the afternoon, adjust your own time so that both time zones Must be heard on a television receiver. Further, even when music data is downloaded without trial listening, the music data (B1, C1,... K1) cannot be downloaded unless the time for broadcasting the music program (A1) is reached. If A1) is broadcast in the evening, the music data (B1, C1,... K
1) Download MD (Mini Disc)
Etc., and cannot go out with this storage device.

Therefore, the present invention has been made in view of the above circumstances, and it is possible to purchase content data such as music data at low cost and without being restricted by time.
Moreover, it is an object of the present invention to provide a method of distributing content data using a data broadcast that allows the user to always use the content data (for example, to listen to music) before purchasing.
