Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for distributing additional information added to content information which is main information such as a digital broadcast program, and more particularly, to a mobile phone, a portable information terminal, a personal information The present invention relates to a distribution device, a distribution method, and a program capable of freely displaying additional information on a screen of a terminal such as a computer.
[0002]
[Prior art]
It is known that digital broadcasting can be distributed not only with content information, which is the main information of a broadcast program, but also with enormous additional information including information related to the content information and information advertised by the content distributor. ing.
[0003]
Accordingly, in digital broadcasting, for example, additional information such as a weather forecast and breaking news is being distributed together with a broadcast program which is one of content information. When this kind of additional information is distributed together with the content information, it is displayed in a part of the television screen by characters and the like, so that the viewer can view the contents of the additional information while watching the broadcast program. it can.
[0004]
As a prior document related to such a technique, for example, there is Patent Document 1 below. In Patent Literature 1, when an advertisement is distributed in an Internet advertisement, a technology is disclosed in which a target is extracted in accordance with user characteristics and the advertisement is distributed to the extracted target user.
[0005]

JP 2001-312643 A
[0006]
[Problems to be solved by the invention]
However, such a conventional digital broadcast distribution method has the following problems.
[0007]
That is, the additional information included in the digital broadcast is displayed on the television screen. As described above, when the additional information is displayed on the television screen, although an extremely large amount of information can be displayed technically, the amount of information is practically limited for the following reasons. That is the current situation.
[0008]
For example, in broadcasting, it is not possible to change the design and resolution of the screen display on the television terminal, so the same screen must be displayed regardless of the size of the screen. Therefore, since it is necessary to correspond to any display area, the amount of information that can be displayed on the screen at one time is limited. For example, due to consideration for a television screen having a small display screen, only news headlines or summaries in short documents and the like can be actually displayed even in news and the like, and information cannot be sufficiently distributed and displayed.
[0009]
For this reason, for example, when distributing more detailed information having a large amount of information, the viewer is frequently requested to switch screens / pages according to the amount of information, which imposes a heavy burden on the viewer. Become.
[0010]
Therefore, in order to effectively convey information by displaying characters on a television screen, the broadcasting station must process the information in advance by devising an expression method. As a result, in the case of news, It can only contain information about the level of the headline, and can not express detailed contents very much. In order to express even more detailed contents or views, expression on a television screen is not suitable, and as a result, the viewer feels unsatisfactory.
[0011]
A digital broadcast including such additional information distributed from the broadcasting station is temporarily stored in a tuner provided with a storage means such as an STB (Set Top Box), and the stored additional information is stored by a user operation. Drawers can also be displayed on the TV screen. However, unlike a PC screen, a TV screen has a low resolution and lacks flexibility in terms of function, such as the inability of the user to set the character size and the like, and is not necessarily an excellent interface for displaying additional information. As a result, there is a problem that the digital broadcasting itself may be prevented from spreading.
[0012]
The present invention has been made in view of such circumstances, and additional information included in a digital broadcast and distributed can be freely displayed on a screen of a portable terminal such as an electronic paper, a PDA, or a personal computer according to a user operation. The present invention aims to provide an information distribution device, an information distribution method, and a program that can fully utilize the large-capacity information distribution capability of digital broadcasting and efficiently use additional information. I do.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, the present invention takes the following measures.
[0014]
That is, the information distribution apparatus according to the first aspect of the present invention includes: content information including main information including program information distributed from a digital broadcasting station; additional information which is information corresponding to the content information; Receiving means for receiving a digital broadcast comprising the listed heading information; storage means for storing the digital broadcast received by the receiving means; and displaying the content information and the heading information to a viewer. Display requesting means for requesting selection of a heading from among the heading information provided, selection information receiving means for receiving heading selection information from a viewer, and storage means when the selection information is received by the selection information receiving means. A first output unit that reads out the additional information corresponding to the stored heading and outputs the additional information to the viewer terminal.
[0015]
According to a second aspect of the present invention, in the information distribution apparatus according to the first aspect, the heading information is included in the content information.
[0016]
According to a third aspect of the present invention, in the information distribution apparatus according to the first or second aspect, when the first output means outputs the additional information to the viewer terminal, the additional information is output to the digital broadcasting station side. A second output unit for outputting notification information is added.
[0017]
According to a fourth aspect of the present invention, in the information distribution apparatus according to any one of the first to third aspects, there is provided a designation information receiving means for receiving output destination terminal designation information of additional information from a viewer; Outputs the additional information to the output destination terminal specified by the output destination terminal specification information.
[0018]
According to the information distribution method of the present invention, the content information including the main information including the program information distributed from the digital broadcasting station, the additional information that is the information corresponding to the content information, and the heading of the additional information are listed. When receiving the digital broadcast including the heading information, storing the received digital broadcast in the storage means, and displaying the content information and the heading information, the viewer is prompted to select the heading from the displayed heading information. When the selection is requested and the heading selection information is transmitted from the viewer, this selection information is received, the additional information corresponding to the heading stored in the storage means is read, and the viewer terminal is transmitted to the viewer terminal. Output.
[0019]
According to a sixth aspect of the present invention, in the information distribution method according to the fifth aspect of the present invention, the heading information is included in the content information.
[0020]
According to a seventh aspect of the present invention, in the information distribution method of the fifth or sixth aspect, when the additional information is output to the viewer terminal, the additional information output notification information is output to the digital broadcast station.
[0021]
According to an eighth aspect of the present invention, in the information distribution method according to any one of the fifth to seventh aspects, when the output destination terminal designation information of the additional information is transmitted from the viewer, the output destination terminal designation is performed. The information is received, and the additional information is output to the output destination terminal specified by the output destination terminal specification information.
[0022]
A ninth aspect of the present invention is a computer readable program including a receiving function, a storage function, a display request function, a selection information receiving function, and an output function as described below.
[0023]
That is, the reception function includes content information including main information including program information distributed from the digital broadcasting station, additional information that is information corresponding to the content information, and heading information that lists headings of the additional information. Receive digital broadcasts. Further, in the storage function, the digital broadcast received by the reception function is stored in the storage means, and in the display request function, when the content information and the heading information are displayed, the viewer is notified of the displayed heading information by the viewer. Request a headline selection from within. The selection information receiving function receives the heading selection information from the viewer, and the output function receives the selection information by the selection information receiving function and outputs the additional information corresponding to the heading stored in the storage unit. The information is read and output to the viewer terminal. Therefore, according to the present invention, the viewer can view only the additional information corresponding to the selected headline from the viewer terminal. In addition, since the viewer can specify the output destination terminal by himself, it is possible to display the additional information from a terminal different from a television such as an electronic paper, a PDA, and a personal computer. For this reason, various additional information can be seen at a favorite place.
[0024]
For example, when newspaper information is distributed as additional information, by viewing the additional information, the user stores the newspaper information in a portable terminal such as an electronic paper or a PDA, and stores the newspaper information at a desired time or at a desired location. In addition to providing the function of a newspaper as a paper medium that can be carried around, all pages can be viewed in a crowded train or the like without expanding the space.
[0025]
Conventionally, when information is directly acquired by a portable terminal such as electronic paper, a PDA, or a mobile phone, communication costs have been a problem. However, acquisition of additional information is not performed by these terminals. Instead, it is performed in conjunction with the distribution of digital broadcasting using a storage type television receiver such as an STB (Set Top Box). For this reason, even a large amount of additional information can be acquired regardless of the communication cost.
[0026]
Further, by distributing data by digital broadcasting, it is possible to distribute data to a wide range of viewers at once. When the information is distributed to many viewers, there is no problem that the load on the distribution equipment increases due to the increase in the distribution amount.
[0027]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0028]
(First Embodiment)
A first embodiment will be described with reference to FIGS.
[0029]
FIG. 1 is a conceptual diagram illustrating an information distribution device to which the information distribution method according to the first embodiment is applied.
[0030]
That is, in the information distribution method according to the present embodiment, the additional information provided from the client 10 and further included in the digital broadcast from the broadcasting station 12 and transmitted is transmitted to the mobile phone, the PDA 16 which is a mobile terminal, and the mobile display. This is a method of distributing to the user-side receiving device 22 for display from a terminal having a display function such as the electronic paper 17.
[0031]
The digital broadcasting system includes a client 10, a broadcasting station 12, distribution means such as an artificial satellite 18, and a user-side receiving device 22. Note that a plurality of communication methods such as a cable television, a terrestrial wave, and a network can be used instead of the artificial satellite 18, but in the present embodiment, the description will be made using the artificial satellite 18.
[0032]
The client 10 includes an additional information database 11, and the additional information database 11 stores various types of additional information included in digital broadcasts and transmitted. Examples of the additional information include character data such as newspaper information, moving image data, still image data, audio data, and program data of a game or the like. The client 10 is connected to the broadcast station 12 via a communication line, and transmits any of the stored additional information to the broadcast station 12 via the communication line based on a request from the broadcast station 12. (S1).
[0033]
The broadcast station 12 includes a digital broadcast transmission device 24, a program management server 26, a real-time broadcast transmission device 28, and a distribution device 30.
[0034]
The digital broadcast transmission device 24 receives the additional information transmitted from the client 10 in step S1, attaches the additional information ID to the received additional information, and registers the additional information in the program management server 26. Also, it creates heading information listing headings of each additional data included in the received additional information, and registers the created heading information with the heading information ID in the program management server 26 (S2). The program management server 26 holds the registered additional information and heading information in association with each other using the additional information ID and heading information ID as registration names.
[0035]
The real-time broadcast transmission device 28 attaches a program ID to program content data, which is broadcast data distributed by the broadcasting station 12 to the user-side receiving device 22 provided in a home, a company, a business office, or the like. (S3). The program management server 26 holds the registered program content data with its program ID as a registered name.
[0036]
The distribution device 30 acquires program content data corresponding to the program ID by designating the program ID to the program management server 26. Further, the additional information is acquired by specifying an additional information ID corresponding to the additional information to be included in the digital broadcast together with the acquired program content data to the program management server 26. Furthermore, by specifying a heading information ID to the program management server 26, heading information corresponding to the heading information ID is obtained.
[0037]
Then, as shown in the data relation diagram of FIG. 2, each heading of the heading information and each additional data (additional data A, additional data B, additional data C, additional data D,. After linking with Z), the headline information is written in the same digital broadcast as the program content data, and the program content data and the additional information are registered as data in the same digital broadcast. In this way, as shown in FIG. 2, the program content data, the additional information, and the heading information are associated with each other. That is, the program ID of the program content data in which the heading information is written and the additional information ID of the additional information included in the same broadcast data together with the program content data are associated with each other on a one-to-one basis. The headings (additional data A, additional data B, additional data C, additional data C,... Additional data Z) in the associated heading information and each additional data of the additional information (additional data A, additional data B, additional data) Correspondence with data C, additional data D,... Additional data Z) is taken (S4).
[0038]
After that, the distribution device 30 transmits the additional information to the user-side reception device 22 in a storage band, which is a band for storing the distributed information, via distribution means such as the artificial satellite 18. The content is distributed to the user 22 (S5).
[0039]
The user-side receiving device 22 receives broadcast data (including additional information and program content data) distributed from the broadcast station 12 as shown in the functional block diagram of FIG. , A hard disk 34 such as an STB, a television 36, a request receiving unit 38, a request processing unit 40, and an additional information communication unit 42.
[0040]
The receiving antenna 32 receives the broadcast data distributed in step S5, and transfers the additional information included in the received broadcast data to the hard disk. Then, the hard disk 34 stores the transferred additional information with the additional information ID as a registered name (S6).
[0041]
The distribution device 30 distributes the program content data to the user-side receiving device 22 via distribution means such as the artificial satellite 18 (S7).
[0042]
The receiving antenna 32 receives the program content data distributed in step S7, and transfers the received program content data to the hard disk 34. Then, the hard disk 34 stores the transferred program content data with its program ID as a registered name, and allows the stored program content data to be broadcast from the television 36. Thus, the program content data is broadcasted in real time (S8). Also, the program content data written on the hard disk 34 can be reproduced and broadcast at an arbitrary timing, even if it is not necessarily in real time.
[0043]
Thus, the program content data is broadcast from the screen of the television 36. As described in step S4, since the heading information is written in the program content data, the heading information is also displayed in a part of the program broadcasted from the television 36, as shown in the schematic diagram of FIG. (S9). FIG. 4A shows an example in which three pieces of index information (additional data A, additional data B, and additional data C) are displayed below the television 36, and FIG. Is displayed on two screens, the program content data is displayed on the left screen, and three pieces of heading information (additional data A, additional data B, and additional data C) are displayed on the right screen. If the number of heading information items is large and cannot be displayed all at once from the screen of the television 36, they are displayed separately. In the example shown in FIG. 4, three pieces of heading information (additional data A, additional data B, and additional data C) are displayed at a time, and when there is more heading information, it is shown in FIG. By selecting "next" from the remote controller 21, the heading information after the additional data D is displayed. Note that the heading information need not always be displayed on the screen, but may be called up as needed and set to be displayed. As described above, various display methods can be realized, and the form is not limited.
[0044]
When it is desired to acquire additional data corresponding to the displayed heading information as shown in the schematic diagram of FIG. 4, the user 20 specifies desired heading information by operating the remote controller 21 and transmits the specified information to the remote controller 21. 21 to the request receiving unit 38 (S10).
[0045]
The request receiving unit 38 receives the specified information transmitted from the remote controller 21. Then, the received specification information is transferred to the request processing unit 40. The request processing unit 40 recognizes heading information corresponding to the designated information, and acquires additional data corresponding to the heading information from the hard disk 34. Then, the acquired additional data is output to the additional information communication unit 42.
[0046]
Upon acquiring the necessary additional data in the additional information, the additional information communication unit 42 transmits the obtained additional data to a terminal having a display function such as the PDA 16 or the electronic paper 17 designated by the user. Alternatively, the additional information communication unit 42 and a terminal such as the PDA 16 or the electronic paper 17 selected by the user may be connected by a data transfer cable (not shown), and data may be transmitted via the data transfer cable (S11). ).
[0047]
Upon receiving the additional data transmitted in step S11, the terminal with the display function, such as the PDA 16 or the electronic paper 17, stores the additional data in its own memory (not shown). When the storage is completed, the reception completion notification information is returned to the additional information communication unit 42. Also in this case, when the additional information communication unit 42 and a terminal such as the PDA 16 or the electronic paper 17 selected by the user are connected by a data transfer cable (not shown), the data is transmitted via the data transfer cable. . The reception completion notification information includes the user ID, the reception device ID, the program ID, the heading information, and the reception completion date / time information (S12).
[0048]
The additional data stored in the memory in step S11 is a display function of the PDA 16 or the electronic paper 17, that is, a property setting function such as character size, color, and font, and a function of setting the number of characters displayed on the screen. , Can be freely displayed by using a screen scroll function, a reduction / enlargement function, and the like. Thereby, the detailed information written in the additional data is freely displayed on the screen of the PDA 16 or the electronic paper 17 (S13).
[0049]
Further, the reception completion notification information returned to the additional information communication unit 42 in step S12 is transmitted from the additional information communication unit 42 to the broadcasting station 12 and further transmitted to the client 10 (S14, S15). By referring to the reception completion notification information, the broadcasting station 12 and the client 10 grasp when and who saw which program and obtained additional data corresponding to which heading information.
[0050]
Next, the operation of the information distribution apparatus to which the information distribution method according to the present embodiment configured as described above is applied will be described.
[0051]
An information distribution device to which the information distribution method according to the present embodiment is applied is realized by a computer that reads a program recorded on a recording medium such as a magnetic disk and the operation of which is controlled by the program.
[0052]
First, the requested additional information is transmitted from the broadcast station 12 to the broadcast station 12 from the client 10 holding various types of additional information included in the digital broadcast (S1).
[0053]
The additional information transmitted from the client 10 in step S1 is received by the digital broadcast transmitting device 24. Then, the received additional information is added to the additional information ID and registered in the program management server 26. Further, heading information listing headings of each additional data included in the received additional information is created, and the created heading information is also registered with the heading information ID in the program management server 26 (S2). The program management server 26 stores the registered additional information and heading information in association with each other using the additional information ID and heading information ID as registration names.
[0054]
Further, the program ID is assigned to the program content data by the real-time broadcast transmitting device 28, and then registered in the program management server 26 (S3). In the program management server 26, the registered program content data is stored with the program ID as a registered name.
[0055]
Next, the program ID is designated by the distribution device 30, and the program content data corresponding to the designated program ID is acquired from the program management server 26. Further, the additional information is acquired by designating the additional information ID corresponding to the additional information to be added to the acquired program content data to the program management server 26. Furthermore, by designating a heading information ID to the program management server 26, heading information corresponding to the heading information ID is obtained.

[0060]
The program content data distributed in step S7 is received by the receiving antenna 32 and further transferred to the hard disk 34. Then, on the hard disk 34, the program content data is stored with the program ID as a registered name, and is also broadcast from the television 36. Thus, the program content data is broadcasted in real time (S8). Note that the program content data written on the hard disk 34 may be reproduced and broadcast at an arbitrary timing even if it is not necessarily real time.
[0061]
Thus, the program content data is broadcast from the screen of the television 36. Since the headline information is written in the program content data, the headline information is also displayed on a part of the program broadcasted from the television 36 as shown in the schematic diagram of FIG. 4 (S9).
[0062]
To obtain additional data corresponding to the displayed heading information, the user 20 specifies desired heading information by operating the remote controller 21, and sends the specified information from the remote controller 21 to the request receiving unit 38. It is transmitted (S10).
[0063]
The transmitted specification information is received by the request receiving unit 38 and further transferred to the request processing unit 40. The request processing unit 40 recognizes heading information corresponding to the specified information, and acquires additional data corresponding to the heading information from the hard disk 34. Then, the acquired additional data is output to the additional information communication unit 42, and further transmitted from the additional information communication unit 42 to a terminal having a display function such as the PDA 16 or the electronic paper 17 designated by the user (S11). ).
[0064]
When the additional data transmitted in step S11 is received by a terminal having a display function such as the PDA 16 or the electronic paper 17, the additional data is further stored in each memory. When the storage in the memory is completed, the terminal transmits reception completion notification information including the user ID, the reception device ID, the program ID, the heading information, and the reception completion date / time information to the additional information communication unit 42. A reply is sent (S12).
[0065]
The additional data stored in the memory in step S11 is a display function of the PDA 16 or the electronic paper 17, that is, a property setting function such as character size, color, and font, and a function of setting the number of characters displayed on the screen. , Can be freely displayed by using a screen scroll function, a reduction / enlargement function, and the like. As a result, the detailed information written in the additional information is freely displayed on the screen of the PDA 16 or the electronic paper 17 (S13).
[0066]
Further, the reception completion notification information returned to the additional information communication unit 42 in step S12 is transmitted from the additional information communication unit 42 to the broadcasting station 12 and further to the client 10 (S14, S15). By referring to the reception completion notification information, the broadcasting station 12 knows when, who viewed which program, and which additional data corresponding to the index information was acquired.
[0067]
