This hierarchical structure has a segment hierarchy composed of segment data 62 and a segment header 60.

The segment data 62 of a conventional FM text multiplex broadcast music program or the like includes a music title or a singer name, which is the data content, and the segment header 60 includes such segment data content or the like. Is included. The information content of the segment identification information has an undefined area.

In the embodiment of the present invention, the UR of a music data distribution source that distributes music data via the Internet is stored in an undefined area of the segment header 60.
L, an information area for information on music distribution such as whether or not distribution is being performed, a time required for distribution, a distribution cost, and the like is created, and these data are entered as segment data 62. Then, at the time of broadcasting a music program, the FM text multiplex broadcasting device 8 sends out a music signal and a text multiplex signal including the music title and information on music distribution as an FM signal.

Then, the tuner 10 receiving the FM signal extracts information related to the music distribution. FIG.
B shows a series of steps performed by the tuner 10 for extracting information related to music distribution from the FM signal.

First, the tuner 10 is connected to the FM signal receiving section 3.
The FM signal is received at step 4 (step S20) and transmitted to the character multiplex signal demodulation unit 38. Here, since the FM character multiplexed signal is transmitted at a higher frequency than the music signal, the character multiplexed signal demodulator 38 extracts only the frequency of the FM character multiplexed signal by a filter (step S21). Then, since the extracted signal is modulated by QPSK (quarternary phase shift keying, 1/4 phase shift keying), character multiplexed data is obtained by demodulating a character multiplexed signal from this signal (step S23). . The segment header described above is added to each data, and the type of data is determined by the segment header identification information included in the header. In this case, the header defined as information related to music distribution is used. By extracting only the data of (1), information on music distribution can be obtained (step S25).

Therefore, the tuner 10 having received the FM signal of the music program through the above steps performs the distribution of the music data distribution source URL of the music data corresponding to the music signal and the distribution of the music data. Information about the music distribution, such as whether or not the music is distributed, the time required for the distribution, the distribution cost, and the like.

Although not shown in the present embodiment, the FM
When including the information related to the music distribution as the character multiplex data in the text multiplex broadcasting device 8, a table in which the information is associated with the music title is created, and the FM broadcast station inputs the text multiplex data. This can be dealt with by providing the software with the table.

(3) Processing for Receiving Music Data Distribution Based on Information Received by FM Teletext Broadcasting In FIG. 4, the system component described above receives the FM signal of the FM teletext broadcasting apparatus 8 A process for receiving distribution of music data based on information will be described.

The FM text multiplex broadcasting device 8 broadcasts a music program by FM text multiplex broadcasting (step S1). The tuner 10 receiving this (step S2) demodulates the music distribution data corresponding to the broadcasted music by the steps described with reference to FIG. 3B (step S3). Then, each time the distribution data is demodulated, information on music distribution is displayed on the display / operation unit 32 under the control of the CPU 36, and the data is transmitted to the HDD recorder 12 with a communication function via the interface 40 (step S).
4). Then, the distribution data is transmitted to the interface 48.
The HDD recorder 12 with the communication function which has received the data records and stores the data in the storage device 44 (step S
5).

When the user of the system component wants to purchase the broadcasted music, he confirms the distribution information of the music by referring to the display of the display / operation unit 32 of the tuner 10 as shown in FIG. After that, an operation of selecting a music desired to be purchased is performed (step S6). In addition,
As described above, instead of checking the information related to the stored music distribution, the user may check the information related to the music distribution of the currently broadcast music and perform the operation of requesting purchase while the music is being broadcast.

Next, the HDD recorder with communication function 12 that has received an operation for purchase from the user activates the network connection software 42 under the control of the CPU 46 and, via the network interface 50,
A connection is made to the URL of the music data distribution source download server 6 included in the distribution data, and download information for requesting download of the music data is transmitted (step S7).

Upon receiving the download information, the download server 6 transmits the selected music data to the HDD with the communication function via the Internet 20.
This is performed for the recorder 12 (step S8). And
The download is completed by the HDD recorder 12 with the communication function storing the music data in the storage device 44 (step S9). When the download is completed, a billing process or the like for purchasing the music data is performed.

Then, the user who has purchased the music data can listen to the music at his / her favorite time.

In the present embodiment, the FM text multiplex broadcasting device 8 transmits information related to music distribution corresponding to the music currently being broadcast, but not the music currently being broadcast. The information on the music distribution of the music that the station wants to introduce to the user may be transmitted separately from the broadcasting of the music.

(4) Effects of the Present Embodiment By configuring the tuner 10 and the HDD recorder 12 with a communication function as described above, when a user listens to a song and desires to purchase the music data, the user can listen to the music. Data can be purchased quickly and reliably. Therefore, there is no burden of storing the name of the music or the like from the time of listening to the music until the purchase stage, or searching the music data separately on the network.

When purchasing music data, the user only has to perform a simple operation input of selecting whether or not to purchase the music data based on the information displayed on the display / operation unit 32. It does not need to be equal. Therefore, the tuner 10 and the HDD recorder 1 with the communication function
2 does not need to be provided with a complicated operation / input unit, so that a simple configuration can be adopted as the device.

Since the burden on the user is reduced, the number of users who actively receive text multiplex broadcasting and purchase music data is increased, and as a result, FM text multiplex broadcasting is increased. Broadcasting and music data distribution, there is a possibility of activating the business.

Further, the HDD recorder 12 with a communication function
Records and accumulates the data in the storage device 44 (step S5), and after confirming the distribution information of the music, the user performs an operation of selecting the music desired to be purchased (step S6).

[0038] Thus, even after listening to the music or not directly listening to the music, the user can quickly purchase the music data by selecting the desired music data.
Therefore, there is no need to operate the tuner 10 while listening to music. Also, the range of music data that can be purchased will be expanded,
Music data more suited to the user's request can be purchased.

Further, in the present embodiment, the FM teletext broadcasting device 8 is exemplified as the transmitting device, but the present invention is not limited to this. For example, the information related to the music distribution may be included in a character multiplexed signal by digital television broadcasting that provides a music program. In this case, it is necessary for the receiving and storing apparatus to be able to receive and demodulate a character multiplexed signal of digital television broadcasting.

In any case, by employing such a transmission device, a user of a tuner receiving the broadcast signal can simultaneously obtain the music and the information for purchasing the music data. Thus, desired music data can be obtained quickly and easily.

Although not shown in the present embodiment, a so-called reservation purchase can be made by inputting information on a music piece that the user wants to purchase into the tuner 10 in advance. In this case, if information related to music distribution in the character multiplexed data demodulated by the tuner 10 matches that inputted by the user in advance as a reservation purchase, the information is automatically connected to the download server of the music data distribution source. Thus, a configuration of acquiring the music data can be adopted.
As a result, the music data that the user wants to purchase can be reliably obtained. In this case, for a song that is expected to have a relatively large number of users who wish to purchase it, it may be possible to make a reservation purchase by inputting a song number or the like instead of a complicated song such as a song title. This can be dealt with by publishing it in a music magazine or the like.

In this embodiment, the tuner 10 and the HDD recorder 1 with a communication function are used as the receiving and storing device.
2 is shown, but the present invention is not limited to this. For example, the tuner itself, which is an FM broadcast receiver, may be provided with a communication function capable of connecting to the Internet. Further, a recording medium such as a flash memory or a CD-R may be used instead of the HDD recorder.
