FIG. 6 shows an example of an embodiment in which a viewer obtains detailed information about a CM by using the metadata of the CM and further reflects it on the preference data of the broadcast receiver.
Here, the CM metadata is additional information that describes the content of the CM. For example, S multiplexed in a TS (Transport Stream) obtained by demodulating a broadcast signal
It is described in I (Service Information). In addition, instead of TS, IP (Internet Proto
col) instead of SI, BiM (Binary Format for M
PEG7) may be used. On the viewer side, there are the broadcast receiver 8 and the mobile terminal 85, and as part of the broadcast receiver 8, there is a preference data recording means 30 and a display means 40. The broadcasting station has a broadcasting satellite 90 that sends a broadcasting signal and a CM server that stores data received from a CM sponsor.

In this example, a service by satellite broadcasting is realized, but a service by digital terrestrial broadcasting may be used, and in this case, a device for sending a broadcasting signal from a terrestrial antenna is provided. Further, in FIG. 6, the broadcast receiver 8 and the mobile terminal 8

ge) It consists of file format text data and video / music data. The XML file is further divided into preference reflection data in which CM genres, keywords, performers, etc. are described, and CM detailed data in which product names, specifications, prices, release start dates, performers, and inserted songs are described. The preference reflection data is a portion reflected in the preference data recording means 30 of the broadcast receiver, and the CM detailed information is a portion which can be viewed on the mobile terminal 85 or the display means 40.

Returning to FIG. 6, the procedure for the viewer to obtain the detailed CM information and further reflect it on the preference data of the broadcast receiver will be described. In step S201, the CM sponsor places the XML file data and video / audio data described in FIG. 7 in the CM server 91. CM at this time
URL (Uniform Reso
urce Locator) as part of CM metadata. CM
Examples of the metadata include the URL and a part of the preference reflection data shown in FIG. 7.

Next, in step S202, the broadcasting station broadcasts CM video / audio data and CM metadata together with the broadcast program. The viewer views the broadcast in real time, or views the content once stored in the broadcast data storage means 12 (not shown). Alternatively, the recommended information is viewed in real time or from the broadcast data storage means 12. When there is a CM that is of interest during such viewing, the viewer sets the mobile terminal 85 in step S203.
Is operated to download the CM metadata from the broadcast receiver 8 to the mobile terminal 85. Next, in step S204, the viewer transmits the URL included in the CM metadata from the mobile terminal 85 to the advertisement server 91, and in step S205, the XML file data, video / audio of the corresponding CM in the advertisement server 91.

Although the data updated in the preference data recording means 30 is the preference reflection data downloaded from the advertisement server 91, the metadata downloaded from the broadcast receiver 8 to the portable terminal 85 in step S203 is used. The preference data recording means 30 may be updated as it is. Further, by providing the mobile terminal 85 with the preference data recording means, it becomes possible to display the recommended program guide and the recommended CM guide recorded in the personal taste data recording means of the mobile terminal 85 on the display unit 79. The updated preference data makes it possible to provide recommended guidance in a timely manner to meet the preference of the viewer. Here, although the advertisement server 91 is accessed via the mobile terminal 85, the internet communication means 60 (not shown) of the broadcast receiver 8 may be used.

Up to this point, the procedure on the viewer side was explained from the time the program was viewed until the recommended guidance was given.
Through FIG. 9, an access information management procedure for notifying the CM sponsor of access information from the viewer and a charging management procedure for the CM sponsor to pay the viewer for the pay broadcast will be described.

FIG. 8 shows an example of an outline of access information management and billing management. The broadcasting station pays a viewing fee for pay program broadcasting for the program broadcasting, a CM broadcasting fee from the CM sponsor,
The source of income is CM metadata broadcasting fees and CM server usage fees. Here, in step S301, the CM server stores the receiver ID number of the broadcast receiver 8 used by the viewer when the viewer accesses the CM server to obtain detailed CM information, and the program ID of the program in which the CM is viewed. To send together. At this time, the receiver ID number is B-CA
S (Broadcast Satellite Conditional Access System)
s) It may be a card number. Next, in step S302, the broadcasting station notifies the CM sponsor of the access frequency information of the viewer to the CM server together with the program ID. By doing so, the CM sponsor can know how much the viewer is interested in the CM over time, and can grasp the timing of introducing a new CM. Further, by checking the program ID, it is possible to understand whether or not the effect of broadcasting the CM on the program is great. If the program is a pay broadcast, the CM sponsor pays the broadcast station a fee according to the access amount from the viewer in step S303. This fee is returned to the viewer as a discount of the viewer's pay broadcast viewing fee in step S304. In such a system, a viewer has an advantage that the viewing fee of this program is reduced by accessing the CM information of the pay broadcast program and viewing it. Further, the CM sponsor can obtain statistical data of the degree of interest in the CM of the viewer.

FIG. 9 shows an example of the procedure of access information management and charging management described in FIG. The broadcasting station has a CM server 91, access information management means 92, and collection management means 93. When the viewer accesses the CM server 91 in step S401, the viewer determines the URL of the CM, the receiver ID number of the broadcast receiver used by the viewer when the CM server 91 is accessed, and the CM detailed information to obtain the CM detailed information. The program ID of the viewed program is transmitted. Then, in step S402, the viewer acquires various information stored in the CM server 91. Further, the access frequency from the viewer to each CM registered in the CM server 91 in step S501 is passed to the access information management means 92 together with the program ID. Further, in step S602, the receiver ID number of the broadcast receiver used by the viewer and the program ID of the program for which the CM is viewed are passed to the collection management means 93.

In step S502, the access information managing means 92 collects the totaled results, for example, every day or
Notify the CM sponsor every week. The CM sponsor who has acquired the information pays a fee according to the access amount to the CM broadcast by the pay program broadcast in step S503. Although no fee is paid for access to the CM broadcast by the free program broadcast, the CM broadcast fee for the free program broadcast is high, and the CM broadcast fee for the paid program broadcast is set low because of the corresponding fee.

In step S600, the collection management means 93 collects the CM broadcast broadcasting fee, the CM metadata broadcasting fee, and the CM server usage fee from the CM sponsor. When the viewer views the pay program broadcast in step S601, the receiver ID number of the broadcast receiver used by the viewer and the program ID of the viewed program are recorded in the CM.

The collection management means 93 manages various collections, but regarding the charge to the viewer, for example, from the total monthly viewing charge calculated in step S601 to the CM server access status counted in step S602. Accordingly, the fee obtained by subtracting the fee collected from the CM sponsor in step S503 is subtracted in step S603.
Bill viewers at.

The present invention is not limited to the above embodiments, but various modifications and applications are possible within the scope of the claims. For example, the CM server may be installed outside the broadcasting station, a link may be used to access the CM server, and the URL may not necessarily be visible. Also, the contents of the CM detailed data and the taste reflecting data are diverse.
