Description

  The present invention relates to an information providing system and an information providing method for providing information to a terminal using broadcasting or communication.

  In conventional television broadcasting, viewers have only watched television programs transmitted from broadcasting stations. Even in the case of digital broadcasting, the viewer can only select the program he wants to watch from the TV program column such as a newspaper.

  In recent years, multi-channel digital satellite broadcasting (hereinafter referred to as CS broadcasting) using a communication satellite (CS) has appeared in order to cope with various preferences of viewers. Although the degree of freedom of the viewer that “the program can be selected from multiple channels” has been increased by the CS broadcasting, the program content and the broadcast date and time are determined in advance by the broadcasting station. The method in which a person selects a program to be viewed from an EPG (electronic program guide), a program guide, or the like is essentially the same as in the past.

  On the other hand, even in the digital broadcasting that is remarkably multi-channeled as described above, even if there is a program that the viewer wants to watch in advance, the program is often overlooked on the day due to the increase or complexity of the program table. . In this way, in order not to miss the program that the viewer wants to watch, the desired program and the desired broadcast content are transmitted to the broadcast system in advance, and a reply mail regarding the broadcast date and time of the corresponding program sent from the broadcast station is sent. In addition, proposals have been made to respond to viewers' desires, such as automatic recording setting to the receiver by a signal for controlling the receiver superimposed on the broadcast wave (Patent Document 1).

Japanese Patent Laid-Open No. 10-276421

  However, for example, the increase in broadcast programs such as the CS broadcast provides the contents determined in advance by the broadcaster in the order determined in advance, so that the number of broadcast channels is increasing. However, since the program that is broadcast at a certain time is not necessarily the program that the majority of viewers want to watch at that time, the uncertainty about whether or not the viewer's request can be satisfied is different from the conventional one. It is not a thing.

  Similarly, due to the benefits of multiple channels, when there are programs that meet the viewer's wishes in the future, the broadcaster will notify the viewers by electronic mail, etc., or automatically at the receiver in response to instructions from the broadcasting station. Even if the recording can be set, the program itself is in accordance with the contents and order determined in advance by the broadcaster, and the program being broadcast at a certain time is the program that the majority of viewers want to watch at that time However, there is no limit to what it has been.

In order to solve the above problems, the present invention takes the following means.
In other words,
A digital broadcast system for providing information to a user of a terminal device having a digital broadcast receiving function,
A BML server that collects viewer browsing request information via a communication network;

The present invention also provides the digital broadcasting system,
A digital broadcasting system using a Web server instead of a BML server.

  In the digital broadcasting system according to the present invention, the statistical processing is based on a method of determining a request to be adopted by majority vote.

  According to the present invention, when there is a content that a general viewer desires to view a broadcast program in a digital broadcast system, the broadcast station performs statistical processing of the desired information, and broadcasts based on the result of the statistical processing. Since the program is determined, the program that the majority of viewers actually desire can be transmitted as a broadcast wave, and the general viewer's wish can be satisfied.

  In addition to statistical processing of the contents of the program directly transmitted by the general viewer, the general viewers can receive a large number of general viewers in a more timely manner by sending out programs including keywords with high rankings in the Internet search site. It becomes possible to follow the program content desired by the person.

It is the figure which showed the structure which produces a program by the viewer vote by a BML server.

It is the figure which showed the program creation by the total result of an internet search site. It is the figure which showed the BML server of digital broadcasting. It is the figure which showed the broadcast program determination process by the statistics of a viewer request. It is the figure which showed the broadcast program determination process by the internet search high-order keyword.

  A preferred embodiment of the present invention will be described with reference to the drawings.

Example 1
FIG. 1 is a diagram showing a configuration for creating a program by audience voting by a BML server. The program creation apparatus 101 includes a program creation unit 103 that determines a program to be broadcast, a program transmission unit 105 that transmits the determined program, and a BML server 107 that receives a request from a viewer. The broadcasting device 110 includes a receiving unit 112 that receives a broadcast wave, a modulating unit 114 that performs modulation processing corresponding to a receiver of the terminal, and an RF transmitting unit 116 that transmits an RF signal. The viewer 130 views the broadcast program through the viewer receiving terminal 120.

  Here, the BML server refers to a server in which information linked from data broadcasting is placed. In digital broadcasting, when a receiving terminal receives a broadcast wave, a TV image flows in the moving image area 403 of the display screen 401 and a screen composed of text and images is displayed in the other data broadcasting area 405 as shown in FIG. The display by the BML server is generally described in a language called BML (Broadcasting Markup Language) included in the broadcast wave, and is performed using the BML browser in the data broadcast area 405.

  A broadcasting company starts the data broadcasting and accesses a content distribution server through a communication network such as the Internet, and provides more detailed contents and interactive services. For accessing the content distribution server, a method using a BML server that displays the communication content by the BML browser simultaneously with the broadcast content, and a Web server that starts up the browser unique to the receiver and displays only the communication content are used. There are two methods.

  In digital broadcasting, since the BML server or Web server as described above is linked to the fusion of communication and broadcasting, and the possibility of providing effective content increases, each broadcaster uses the BML server and Web server. Various efforts are being made to provide information.

  In one-segment broadcasting, which is a broadcasting format included in digital broadcasting, the BML server is generally called a primary link server, and the Web server is generally called a secondary link server.

  In the present invention, the viewer 130 transmits the program content desired to be requested to the BML server 107 on the broadcasting station side via the data broadcast display area 405 of the viewer receiving terminal 120, and the program creation unit 103 receives a plurality of viewers from the viewer. Statistical processing is performed on the sent request, a program corresponding to the content with the most users is determined from program contents owned by the broadcasting station, and the program transmission unit 105 transmits the program.

  FIG. 5 shows such a broadcast program determination process. The broadcast station has a broadcast station-owned program list 501 such as programs 1 to 4 as a program database of the program creation unit 103. When the viewer 130 sends a program request to the BML server 107 from the screen such as the data broadcast display area 405 in FIG. 4 via the viewer receiving terminal 120, the statistical processing unit 503 performs statistical processing on all requests in the program creation unit 103. I do.

  Next, the broadcast content determination unit 505 determines the program content most requested by the viewer, extracts a corresponding program from the broadcast station owned program list 501, and transmits a broadcast wave from the program transmission unit 105.

  By such processing, the viewer can watch the program including the content that has been requested most at that time on the viewer receiving terminal 120.

(Example 2)
FIG. 2 is a diagram showing a configuration for creating a program by audience voting by a Web server. The only difference from FIG. 1 is that access from the viewer to the broadcasting station side is not the BML server but the Web server, and the connection destination is the Web server 201. The broadcast program determination process other than using the Web server 201 is the same as that of the first embodiment.

  The content displayed on the BML server is specialized for data broadcasting of digital broadcasting, and is not based on the content description language used in PCs and mobile phones such as HTML and CHTML, but for broadcasting called the BML language. The content layout was described in a description language. Furthermore, texts and images to be referred to have to be created in a format based on a standard established by ARIB (Radio Industry Association).

  On the other hand, since the Web server is displayed by a general browser of the terminal, it is not necessary for the viewer to use the digital broadcast receiving terminal to send the request, and any information device that can be connected to the Internet. It is not limited at all.

(Example 3)
FIG. 3 is a diagram showing a configuration for creating a program based on a search keyword aggregation result published by an Internet search site. There are two differences from FIG. 1 and FIG. 2. The first point is that the program receiving device 120 is not accessed from the viewer receiving terminal 120, and the second point is instead of the BML server 107 or the Web server 201 that accepts the viewer's request. The Internet search site totaling server 301 is used.

  FIG. 6 shows a process of determining a broadcast program using the search upper keywords published by the Internet search site. The broadcast station has a broadcast station-owned program list 601 such as programs 1 to 4 as a program database of the program creation unit 103. In the list, keyword data indicating program contents is assigned to each program. On the other hand, the Internet search site totaling server collects search upper keywords published by the Internet search site in real time.

  Next, the broadcast content determination unit 505 refers to the search high-order keyword, collates the search high-order keyword most interested in the Internet with the keyword data indicating the program content included in the 601, The most relevant program content is determined, the corresponding program is extracted from the broadcast station owned program list 601, and a broadcast wave is transmitted from the program transmission unit 105.

  By such processing, the viewer can watch the program related to the content that is most interesting among the Internet users at that time on the viewer receiving terminal 120.

  As described above, three examples have been shown. In the present invention, the statistical method of the request from the viewer in the first and second examples may be a majority voting method, and various things such as weighting current information. However, this is not a limitation.

  In addition, regarding the method of determining the program to be broadcast from the statistical results in the first and second embodiments, a viewer request submission format that can identify the program from the broadcast station-owned program list is created in advance, and a request is made in the format. There are various ways to get them, and this is not a limitation.

  Similarly, in the third embodiment, the keyword data indicating the program content and the search upper keyword of the Internet search site are collated by defining a method for the program when there is a matching keyword, and defining a distance measure between the keywords, Various methods such as a method of determining the program having the keyword having the closest distance measure are conceivable, and the method is not limited in any way.

  The first embodiment or the combination of the second embodiment and the third embodiment is also included in the present invention. For example, a broadcast program is determined by statistical processing referring to both a request from a viewer and an upper search keyword of an Internet search site. May be.
