Description

[0001]
[Industrial application fields]
The present invention relates to data contents broadcast by data multiplex broadcasting in current television broadcasting, FM audio broadcasting, etc., and data broadcast together with broadcast programs in digital television broadcasting and digital audio broadcasting that will become mainstream in the future. This relates to a method of using content.
[0002]
[Prior art]
Data multiplex broadcasting is performed in which various data is broadcast by being multiplexed with a broadcast program by television broadcasting or FM audio broadcasting. In current analog broadcasting, data is multiplexed and broadcasted separately from broadcast programs. To use the data, a special circuit configuration is required for the receiver, but both television broadcasting and audio broadcasting are digital broadcasting. Since broadcast programs and data are broadcast as the same packet, the use of data does not require a special circuit configuration.
[0003]
Until now, digital broadcasting has been carried out only by satellite waves, but is starting to be started by terrestrial waves from December 2003.
Compared to satellite wave broadcasting with a single service area in the whole country, terrestrial broadcasting, which uses a relatively narrow area as a service area, provides detailed information closely related to the area not only in the program content but also in the data content to be broadcast. Provision is possible.
[0004]
FIG. 1 shows the relationship between a broadcast program and a data program shown as an example of television broadcasting.
(A) of the figure shows the transmission status of broadcast programs and advertisement (CM) programs in television broadcasting, and (b) shows the transmission status of data and CM additional information.
Note that the passage of time is from left to right.
[0005]
In the case of a television broadcast program, a pre-program title 11, a first program main part 13, a main program main part 15, and a post-program title 16 are sent out during a period 10 and 18 for operation of a broadcasting station called a station break (stevure). Before CM12, middle CM14, and after CM17 sent by the program production station (key station). Further, during the station break, the transmitting station (local station) transmits the station break CMs 20 and 28.
In this example, the broadcast program is composed of two parts, but it goes without saying that the broadcast program may be composed of more parts such as a relay program or a movie.
[0006]
As shown in (b), the CM additional information 20, 22, 24, 27 and 28 are sent simultaneously with the sending of the CMs 10, 12, 14, 17 and 18, respectively, and the data programs 21, 23 and 25 are television broadcast programs. Dispatched when is being sent.
[0007]
As described above, when a broadcast program is being sent, information related to the broadcast program, such as quizzes and questionnaires for participation of viewers, information on program contents, inquiries about the program, and various information unrelated to the program Is transmitted as a data program, and when a CM program is transmitted, information supplementing the CM or CM additional information for promoting the use of the CM is transmitted.
[0008]
In the CM additional information, URL, inquiry telephone number, data request address, etc. data and CM text which is a short character string such as commercial program name, product pet name, catchphrase, event guide, etc. are described as the advertising source contact information. ing.
[0009]
Although the CM additional information is transmitted for the purpose of using the CM program, the CM additional information is more specific than the CM program, and there is much information that inevitably needs to be recorded. Therefore, in order to use the CM additional information, it is necessary to record the CM additional information on some recording medium. In addition, it often takes some time for the viewer to recognize the necessity of recording the CM additional information.
In order to cope with such a situation, the transmission of the CM additional information 20, 22, 24, 27, and 28 starts slightly later than the transmission of the CMs 10, 12, 14, 17, and 18, respectively.
A broadcast program and a data program are transmitted on separate channels in the case of analog broadcasting, but are transmitted in a single channel in the case of digital broadcasting.
[0010]
Information on various products is broadcast on television commercials, and is used to stimulate consumers' desire to purchase and select products. However, conventional CM programs have only a one-way product information transmission function to viewers. Therefore, even if a consumer who watches a CM program of a certain product is inspired to purchase, it does not necessarily cause a specific purchase behavior.
[0011]
Reasons why CM program broadcasting does not lead to purchase behavior include the following. First of all, it is difficult to accurately grasp the contents of the broadcast CM program. The broadcast time of many CM programs is very short, such as 15 seconds or 30 seconds. For this reason, even if there is product information, price information, and contact information necessary for purchasing a product in a CM program, it is extremely difficult to record them.
[0012]
In addition, CM programs are repeatedly broadcasted unlike ordinary programs that are broadcast only once, but unlike general programs that are broadcasted, broadcast notifications are never given. For this reason, even if the viewer finds the necessary CM program, it is difficult to prepare for recording the necessary information because it is unknown when there will be another broadcast.
[0013]
Furthermore, since there is no means for the viewer to record a large amount of information obtained from the CM program or to compare the contents with each other, it is difficult to determine whether or not to lose the purchase.
[0014]
Even if a contact number such as a telephone number or homepage address (hereinafter referred to as URL (Uniform Resource Locator)) is broadcasted in the CM program, make a note of the telephone number and make a call, or use a browser on a personal computer. It is often abandoned because of the complexity of opening the homepage.
[0015]
In TV e-commerce, the flow of advertising, product information transmission (CM program broadcast), viewers, viewer purchasing behavior, consideration payment, advertising source, product advertisement, purchase, and consideration payment flow is configured. Therefore, it is a necessary condition that the motivation from product advertisement to purchase is smoothly and efficiently performed.
[0016]
To that end, firstly, it is necessary to eliminate as much as possible the problems of the prior art that lie between the viewing of commercial programs and the purchase behavior.
[0017]
Secondly, it is possible to maintain the maximum return on investment for the first time by tracking the audience that the CM program produced by the advertising source has produced an advertising effect and feeding it back to the advertising plan. It is necessary to have a function that can always collect data that associates the management number of each CM program with what kind of attribute such as age and gender the purchase behavior has occurred by some method.
[0018]
It has been proposed that digital broadcasting has a high affinity with other digital communication means such as the Internet, and those having communication line connection terminals become standard products. FIG. 2 shows a basic configuration example of a digital television receiver.
[0019]
In digital television broadcasting, both broadcast programs and data programs are transmitted as data packets. Therefore, the receiving device 30 includes a tuner and a decoder for extracting broadcast programs and data programs from the radio waves captured by the antenna 31 from the broadcast radio waves. 34 is added to the computer.
The received broadcast program is composed of a CRT display, LCD display, PDP, etc., and is output / displayed on a display device 32 including a speaker and the like.
[0020]
A CPU 35, a memory 36 as a ROM / RAM, and a modem 37 connected to a communication line 40 are connected as computer elements to the bus 33 to which the image receiving circuit 34 is connected.
Further, a remote controller interface 38 for the infrared remote controller 41 and a high-speed interface 39 for the recording / recording / reproducing apparatus 42 are connected to the bus 33 as accessory devices of the receiving device. In the case of a hunting broadcast receiver, a CAS (Conditional Access System) interface for restricting use is further connected.
[0021]
FIG. 3 shows a method of using broadcast data disclosed by the present inventors in Japanese Patent Application No. 2000-257000 (Japanese Patent Laid-Open No. 2002-77872).
This system includes a television broadcasting station 50, a set-top box 51 as a receiving device, a display device 52, and a CM management server 55. Between the set-top box 51 and the CM management server 55, there is a network 54 using the Internet. The set top box 51 further includes a large capacity recording device such as a hard disk. Various operations are performed using the infrared remote controller 53.
[0022]
A broadcast signal transmitted from the television broadcasting station 50 is taken into the set-top box 51 via the television receiving antenna, and a television image is displayed on the display device 52.
[0023]
When the viewer sets the CM data storage mode in advance and the viewer views the CM and operates the remote controller 53, the CM additional information of the current CM and the still image data obtained by capturing one frame in the CM are displayed. The thumbnail screen and the CM video / audio data after the CM head position mark in the delay memory for 15 seconds and the reception channel number reception date and time are collectively stored in the storage medium as one item.
[0024]
As a recording device, a fixed disk of about several gigabytes is used, the total data length, reception date / hour / minute / second, reception channel, CM additional information, CM text, CM program data, CM video compression data, CM audio compression data. , And an automatic deletion permission flag, for example, CM data equivalent to 4 Mbytes is accumulated in the case of a CM of 15 seconds.
[0025]
Individual CM information data in the CM information database is extracted for each CM information data using an advertisement source name and a product classification code input by the viewer to the set top box 51 as keys, and displayed on the display device 52.
In addition, when the “thumbnail button” is clicked, the display screen is switched to video, and the CM is displayed as a moving image and the sound is reproduced.
Clicking the “URL” button in the display screen calls the home page of the advertisement source, and clicking the “TEL” button calls the phone.
[0026]
Although CM information is used in this way, a large-capacity storage device such as a hard disk is required in the set-top box, which increases the price of the set-top box.
[0027]
In addition, it has been proposed to use this communication line connection terminal to communicate with a broadcasting station to apply a quiz and answer a questionnaire.
However, the operation unit of the television receiving apparatus is not suitable for use for sending out information, and as such is extremely inconvenient for communication.
In addition, since the television apparatus does not have a full-fledged communication function, it is difficult to communicate complicated contents such as ordering even though simple communication can be performed.
[0028]
SUMMARY OF THE INVENTION
In the present application, a method for using data multiplex broadcasting and data multiplex broadcasting that can cope with such a situation and can perform complicated communication without requiring a mass storage device such as a hard disk in a set top box. A receiving device is provided.
[0029]
For this purpose, data such as a data broadcast program or CM additional information is not stored in the receiving device, but the data is taken into an e-mail (hereinafter simply referred to as “mail”) by a communication function of the receiving device, and is stored in a personal computer or a mobile phone. Send e-mail to viewer terminal such as telephone.
The viewer takes out the URL, telephone number, address, data, etc. from the received mail and uses them.
[0030]
The television broadcasting station, as a data broadcast corresponding to a television program, includes a URL for inquiries about program contents, data such as a telephone number and address, or detailed data on program contents such as recipes, an advertisement source URL as CM additional information, Broadcast data such as telephone numbers and addresses.
[0031]
The viewer sends a command to the set top box using the remote controller during the program is being broadcast, and the set top box creates an e-mail incorporating the data being broadcast at that time and is designated in advance. E-mail is sent to the viewer's e-mail address using the communication function.
[0032]
Viewers receive e-mails with personal computers or mobile phones, and take out the captured data for use.
[0033]
This configuration eliminates the need to use a large capacity storage device for the set top box.
Also, viewers are much easier to process data than personal computers or mobile phones compared to set-top boxes, and viewers command mail when necessary data is being sent. Data can be made available with a simple operation.
In addition, e-mail C.I. C. By using the function, it is possible to send to a plurality of mail addresses.
[0034]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
In the embodiments described below, only examples in which the invention according to the present application is applied to digital television broadcasting are shown, but the invention according to the present application is not limited to analog data in current television broadcasting, FM audio broadcasting, etc. Needless to say, the present invention is also applicable to multiplex broadcasting and digital audio broadcasting.
[0035]
FIG. 4 shows an embodiment of the system according to the present invention.
This system includes a television broadcasting station 60, a set top box 61, a display device 62, a remote controller 63, an Internet server 65, a communication terminal 66, and a data management server 67. The set top box 61, the Internet server 65, and the communication terminal 66 are included. The data management server 67 is connected to a network 64 using the Internet.
[0036]
The basic configuration of the set top box 61 is the same as the existing one shown in FIG. This different function is realized by changing the program written in the ROM constituting the memory 36 of the existing device. Depending on the form of use, it is necessary to select the type of RAM. Since this is not a matter that must be done, a new explanation is omitted.
[0037]
The first feature of the program written in the ROM is a mail function. By this mail function, a mail having the text specified by the data or CM additional information specified by the viewer is created and transmitted to the mail address specified by the viewer.
[0038]
The broadcast signal transmitted from the television broadcasting station 60 is taken into the set top box 61 via the television receiving antenna, and the television image is displayed on the display device 62.
In data broadcasting, in addition to data programs, URLs for inquiries about program contents, telephone numbers, addresses and other data, detailed data on program contents such as recipes, etc. are broadcast. The original URL, telephone number, address, and other data are broadcast.
[0039]
On the receiving side, the viewer receives the data broadcast program together with the broadcast program and the CM additional information program together with the CM program in the set top box 61, and the broadcast program and the CM program are displayed on the display device 62. The data program and the CM additional information are displayed on the display device 62 simultaneously with the broadcast program and the CM program, or are displayed separately by switching the display function.
In this case, an auxiliary display device for displaying a data program and CM additional information may be provided separately from the display device 62.
[0040]
In FIG. 4, when the viewer operates the remote controller 63, the set-top box 61 uses the data broadcast content or CM additional information as the text, and the communication terminal 66, which is a personal computer or mobile phone designated by the viewer, is used as the transmission destination address. A mail is created and transmitted via the network 64 and the Internet server 65.
[0041]
When the viewer makes an inquiry about a data broadcast program or an inquiry about a CM, information is obtained from the URL of the data management server 67 where detailed data is stored. In some cases, information is obtained by telephone or mail based on information such as a telephone number or an address.
[0042]
Needless to say, the network 64 and the Internet server 65 shown in FIG. 4 can be replaced with a home network and a home server.
By doing so, it becomes easy to use the data received by the television receiver or the like in another device, the communication cost by using the external network is reduced, and leakage of usage information to the outside can also be prevented. .
[0043]
In addition, this embodiment is a so-called push type system in which a mail having data content as a text is transmitted from the set top box 61 to the communication terminal 66 by the operation of the viewer.
Instead of this push type, a so-called pull that causes data contents to be created as a text by operating the set-top box 61 from a different location using a data communication device such as a mobile phone and transmitted to the data communication device. It can also be a mold system.
[0044]
FIG. 5 shows a configuration example of the remote controller 63.
The channel selection key 70 of the remote controller 63 has a character input function used in a cellular phone, and communication conditions such as an e-mail address necessary for sending an e-mail using this key are set in the set top box 61. , Display the operation content on the display device 62, set the communication condition, and store it in the memory in the set top box.
[0045]
Although the operation keys 72 and 73 are used also when setting communication conditions, an important function is to take in data broadcasting contents or CM additional information and send a mail addressed to the communication terminal 66 as the text. .
[0046]
The number of e-mail addresses that can be addressed is not limited to one. It is also possible to use a plurality of e-mail addresses properly. C. You can also send mail to multiple addresses at the same time using the function.
The operation key 71 is used for that purpose, and in this example, three addresses A, B, and C can be addressed.
In addition, as the setting of the mail transmission source, it is possible to use the device ID entered at the time of shipment of the set top box.
[0047]
Even if you notice a data broadcast or CM for which you want more information, you may not be able to immediately operate the remote controller 63 because you do not have a remote controller or do something else.
Even in such a case, if the data broadcast program or the CM additional information is stored in the set top box 61, it can be transmitted as a mail without any problem if the delay is a little.
For this purpose, the data being received is temporarily stored in the memory in the set top box 61, and the subsequent data is overwritten.
[0048]
Even if the mail transmitted to the communication terminal 66 is viewed, it may be difficult to determine what kind of data it is because it is only text information. In order to cope with such a situation, a frame of a broadcast program or CM program is captured as a still image, converted into a display thumbnail, and attached to a mail.
