Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiplex broadcasting system, a receiver, a transmitting device, and a multiplex broadcasting method. And a multiplex broadcasting technique for transmitting to a receiver in a transmission area.

[0002]

2. Description of the Related Art Hitherto, a multiplex broadcasting system in which various data are multiplexed on a broadcast wave has been put to practical use. For example, a digital audio broadcast (Digital Audio Broadcasting) that multiplexes data into a radio broadcast.
(sting: DAB) and a text multiplex broadcasting system in which text broadcasting is multiplexed on a television signal.

In such a multiplexed broadcasting system, various attempts have been made to take advantage of the multiplexing and add bi-directionality to a broadcast which has conventionally only transmitted information unilaterally. For example, as shown in Japanese Patent Application Laid-Open No. 9-46653 and the like, there is a type that multiplexes data of options for answering to a quiz or the like on a broadcast signal of a television program such as a quiz. In such a system, the receiver uses the multiplexed data to display options on a TV screen, and the viewer operates a remote controller or the like,
When one of the options is selected, it is transmitted to the data processing device via a communication path such as a telephone line. By processing the received data, the data processing device determines the correct answer of the quiz and counts the questionnaire. Note that such questionnaires and quizzes can be performed by radio broadcasting. In this specification, even in the case of a radio broadcast, a user who listens to and participates in the broadcast is referred to as a “viewer” in the same manner as a television broadcast.

[0004] Naturally, as a method for general viewers to participate in such questionnaire surveys in television broadcasting and radio broadcasting, a method of participating using telephone or facsimile without using multiplexed data has hitherto been used. Has been put to practical use. FIG. 10 shows an example of a conventional telephone voting system. In this example, when a question is presented via broadcasting, a response destination telephone number for reception is prepared for each of a plurality of answers to the question. Viewers
Call one of the telephone numbers according to your answer. The totaling is performed by counting the number of incoming calls for each answering destination telephone number at the central office.

[0005]

However, whether or not multiplex broadcasting is used or not, it takes a considerable amount of time to collect the survey results for each region in a conventional questionnaire survey or the like. For example, when participating in a program, viewers who answer the questionnaire will be informed of the area where they live by telephone or facsimile information, and this will be counted for each area, or a different response destination will be prepared for each area, It was necessary to have viewers call different numbers for each region. And even with these preparations, viewers can enter the wrong location name,
The possibility of calling the wrong number was pointed out, and the problem of how to ensure the accuracy of counting was also pointed out.

[0006] Further, if it is intended to add to the broadcast bilaterality in that the content of the broadcast is determined in response to the viewer's request, instead of simply counting the questionnaire, etc. It is possible to provide different programs for each region, but in such a case, if it is not possible to quickly and accurately identify the region of the viewer, broadcasting with excellent interactivity can be realized. There was a problem that it was not possible. Such a problem is that when a viewer is traveling in a car, for example, the viewer may not be able to correctly recognize his / her own location and cannot be overlooked.

[0007] Therefore, the present invention, in a multiplex broadcasting system such as DAB, handles information about the location where a viewer, that is, a receiver is present, thereby adding bidirectionality with the viewer to the location information. The purpose of the present invention is to secure in a form and improve the convenience of a multiplex broadcasting system. It is another object of the present invention to provide various services using such a multiplex broadcasting system.

The multiplexed signal received via the receiving antenna 51 is demodulated by the receiving unit 52, and a process for extracting the transmitter identification signal TII therefrom is performed (step S200). Further, a process of demodulating an audio signal from the multiplexed signal and a process of displaying data on the display unit 66 are performed (step S210). The demodulated audio signal is
Output from the speaker 55 via the amplifier 53. Therefore, the viewer can use the receiver 50 to listen to the sound broadcast from the broadcasting device 30. In addition, if the data superimposed for the questionnaire is a stand-alone receiver 50A, the data superimposed on the display unit 66 as shown in FIG. 6 and the computer 80 as shown in FIG. In the case of the receiver 50M, the data is displayed on the monitor 87, and the viewer can easily read this data.

Next, the receiver 50 receives an input for the questionnaire (step S220). The input may be made by inputting a number in front of the option using the keyboard 62, or by selecting an applicable item by operating an arrow key. Of course, instead of choosing an option, the keyboard 62
May be used to input the character of the answer as appropriate.
Note that, as shown in FIG. 7, if the receiver has the microphone 95, the answer may be input using voice input / voice recognition.

When all the necessary options are selected and no correction is selected, it is determined that the input for answering the questionnaire has been completed (step S230), and the receiver 50 next uses the line termination device 69. A calling process is performed (step S240). The calling process is to dial the transfer destination included in the survey information of the questionnaire. In the present embodiment, the telephone call is made to the line termination device 37 of the service providing unit 34 which provided the questionnaire data answered by the viewer. Is the process of applying When the connection of the service providing unit 34 to the line terminating device 37 is completed by the calling process, the data (response data) answered to the questionnaire is transmitted to the transmitter identification signal TII.
At the same time, a process of transferring to the service providing unit 34 is performed (step S250). At this time, the receiver 50 includes the data such as the number of the option answered by the viewer using the keyboard 62 or the like, the transmitter identification signal TII extracted from the DAB broadcast signal, the valid time included in the survey data, and the like. Is also transferred. When all the data has been transferred, the receiver 50 disconnects the connection to the telephone network, and ends the processing.

When a response (response data) to the questionnaire is sent from the receiver 50 in this way, the broadcasting device 3
The corresponding service providing unit 34 of “0” performs a process of inputting the response data (step S150). In FIG. 8, only the transfer of the response data from one receiver is illustrated.
Response data will be sent one after another. Therefore, while successively storing the input response data in a storage device such as a hard disk, the input of such response data is sequentially accepted, and the process waits until a predetermined time elapses (step S160). If it is determined that the predetermined time has elapsed, the input of the response data is terminated, and a process of totalizing and displaying a large number of received response data for each region is performed (step S170). In the present embodiment, the validity / invalidity of the received data is also determined when the data is totaled. For example, if data of a number corresponding to an impossible option is sent or data outside the valid time is sent, these data are invalid and are not included in the totaling. The determination of such data is made by the receiver 5
0 can be performed, but if the time of the clock built in the receiver 50 is shifted, it is difficult for the receiver 50 to accurately limit the transfer of response data only within the valid time. Can be considered. Therefore, as in the present embodiment, it is more accurate to make a determination on the broadcast device 30 side. Of course, from the viewpoint that useless data is not transferred, it is of course desirable that the receiver 50 limit the data that can be processed on the receiver 50 side.

In this embodiment, response data to a questionnaire or quiz includes a transmitter identification signal TII. Therefore, the answers to the questionnaire can be totaled for each region. Since it is not necessary for the viewer to input the position where the viewer exists, the information on the area where the viewer lives can be obtained very accurately. As a result, there is no reply that the area name cannot be specified due to omission of entry or the like, and the accuracy of questionnaire totalization and analysis can be ensured. In the present embodiment, the transmitter identification signal TII extracted from the multiplexed signal is transferred as it is. However, the transmitter identification signal TII may be transferred after being converted into a form such as a regional code assigned to each transmission area. Further, since the receiver 50 can receive the multiplexed signals from the plurality of transmitters 40 and determine the electric field strength of each transmitter identification signal TII, not only the main transmitter 40 but also the receivable signals can be received. The transmitter identification signal TII of the other transmitter 40 outputting the multiplexed signal is also determined, and more detailed area information may be transferred. Service provider 3
The survey result analyzing unit 36 of 4 collects the response data for each area using the transmitter identification signal TII, and outputs the totaled result to the output device 39 provided in the service providing unit 34. As the output device 39, for example, a CRT display or a printer can be used. Therefore, the tally result is displayed on a display such as a CRT or printed. Of course, notification by voice may be performed.

It is to be noted that the aggregation result analyzed by the survey result analysis unit 36 may be used only for the broadcasting device 30 side, but is output to the service selection unit 35 and is superimposed on a voice signal or the like as in the questionnaire questionnaire. Alternatively, it may be selected using the DAB broadcast signal and notified to the viewer. In this case, in order to easily display the tabulation results and the analysis results, the results may be displayed in a form such as a graph.

In the above embodiment, the replies to the questionnaire (response data) are totaled by each service providing unit 34 in the broadcasting device 30. However, the device for performing such processing need not be installed in the broadcasting device 30. It is not always necessary, and may be installed separately from the broadcasting device 30 as shown in FIG. In FIG. 10, a device that performs tallying on the responses to the questionnaire is installed as a tallying distribution center 22 separately from the broadcasting device 30. Such an aggregation delivery center 22
It is also preferable to have a function as a collection and delivery center that sends out prizes and the like to questionnaire applicants and correct answerers of the quiz, in addition to counting answers of questionnaires and quizzes.
Since the receiver 50 transfers the response data via the telephone network NT, the aggregation and distribution center 22 may be installed anywhere as long as it can be connected to the telephone network NT. Therefore, it may be installed in an area where driving of a delivery vehicle such as a truck is easy. Further, similarly to the transmitter, it may be provided for each transmission area.

<Second Embodiment> Next, a second embodiment of the present invention will be described. FIG. 11 is a flowchart showing processing on the transmitting side and the receiving side of the multiplex broadcasting system in the second embodiment. In this embodiment, a viewer makes a request for content such as music based on data transmitted by a multiplex signal, instead of transmitting data such as a questionnaire or a quiz superimposed on a broadcast signal. .
For this reason, in the multiplexed signal transmission process (step S300), the broadcast device 30
Request data (stored information) is multiplexed, and a process of adding a transmitter identification signal TII to the multiplexed data is performed.
The request data is data such as a title of a song that can be broadcast in response to a request from a viewer, an artist name, and the like, and is data stored in the data storage unit 44 in advance. In this case, the data storage unit 44 stores the data for receiving the request, and the data of the music actually broadcast in response to the request is stored in the audio signal storage unit 43. FIG. 12 shows an example of the audio signal storage unit 43 and the data storage unit 44. In this embodiment, the data storage unit 44 stores, in addition to the content of the content that can be broadcast in response to the request (for example, the name of the song and the name of the singer), management information of the stored content (for example, the transfer destination of the request, Subject, expiration date for transfer, etc.) are also stored. Service provider 3
4 receives these data from the audio signal storage unit 43 and the data storage unit 44 and superimposes the data on the multiplexed signal as request data.

The request data is transmitted to each of the transmitters 40A and 40A together with the broadcast signal and the transmitter identification signal TII.
0B... 40M, the receiver 50 existing in each transmission area receives this, and first extracts a transmitter identification signal TII as in the first embodiment (step S40).
0), demodulation of the audio signal and display of the request data are performed (step S410). Requestable music data may be displayed in a list on the display unit 66, or may be arranged hierarchically and displayed in a genre. The viewer inputs the number of the requested music using the keyboard 62 while referring to the display on the display unit 66 (step S42).
0). Upon completion of the input of the request by the viewer (step S430), the receiver 50 performs a calling process (step S440), and performs a process of transferring the request data to the broadcasting device 30 (step S4).
50). At this time, as information indicating the location of the receiver 50 that transfers the request data, the transmitter identification signal TI
I is also transferred.

Upon receiving the calling process from the receiver 50, the service providing unit 34 of the broadcasting device 30 is connected to the receiver 50 via the telephone network NT. After the connection via the telephone network NT is completed, the service providing unit 34 inputs the request data from the receiver 50 (step S350), and performs a process of searching for the content corresponding to the request (step S360). Specifically, the audio signal storage unit 4 uses a number (subject) such as request data as a key.
A process for extracting the music data stored in the storage device 3 is performed. In this embodiment, the content broadcasted in response to the request is music, but the content is not limited to music, but includes speeches, lectures, information on traffic congestion, weather forecast, event information, and the like. No problem.

The service providing unit 34 includes the audio signal storage unit 4
Then, the content extracted from 3 is output via the service selection unit 35 (step S370). At this time, the transmitter 40 that broadcasts the content is specified using the transmitter identification signal TII received earlier. As a result,
The content such as music requested by the viewer is broadcast from the transmitter 40 in the transmission area where the requested viewer exists.

According to the second embodiment described above, the viewer can not only easily request content such as music using the data included in the multiplexed signal, but also the entire multiplex broadcasting system 20. Also, the content can be broadcast only to the transmission area where the requested viewer exists, and the broadcast system can be operated efficiently. Therefore, for example, even when a viewer is watching a broadcast using a receiver 50 provided on a mobile body such as an automobile, broadcasting the content corresponding to the request from the transmitter 40 corresponding to the traveling area of the automobile. Can be. In addition, the broadcasting system has an effect that different services can be provided for each region.

<Modification of Second Embodiment> Next, a modification of the above-described second embodiment will be described. In the second embodiment,
Data for the viewer to make a request was superimposed on the multiplexed signal and delivered to the receiver 50. On the other hand, a configuration can be considered in which the receiver 50 acquires data (for example, a song name or an artist name) for making a request via the telephone network NT. In this case, the telephone number of the connection destination connected via the telephone network may be extracted from the multiplexed signal, or may be stored in the receiver 50 in advance.

The processing on the broadcast device side and the receiver side in this modification is not greatly different from the processing shown in FIG. 11, and is not shown. The receiver 50 accesses the stored information stored in the service providing unit 34 of the broadcasting device 30 via the telephone network, and in FIG. And the like, and the information is displayed on the display unit 66. Processing following input of request by viewer (step S42)
0) are the same as those in FIG. Even when the data for the request is obtained through the telephone network, the receiver 50 adds the transmitter identification signal TII when transferring the request data to the broadcasting device 30 side.
This transmitter identification signal TII has previously been transmitted to the receiver 5 by the viewer.
When the DAB broadcast signal is received due to 0, the transmitter identification signal TII stored in the memory 61 may be used at that time. Of course, if the viewer is currently receiving a DAB broadcast signal, the transmitter identification signal included in the received multiplexed signal may be extracted and transferred.

With this configuration, similarly to the second embodiment, the viewer can use the receiver 50 to easily make a request for broadcast contents. Further, as a broadcasting system, the requested content can be transmitted from the transmitter 40 in the area where the requesting viewer exists, and efficient operation of the system can be realized.

<Third Embodiment> Next, a third embodiment of the present invention will be described. FIG. 13 is a flowchart showing the processes on the broadcast device 30 side and the receiver 50 side in the third embodiment in correspondence with each other. In this embodiment, the viewer
As in the embodiment, a request is made to the broadcast device 30, but the content delivered in response to the request is delivered to the receiver 50 not as a broadcast signal but as multiplexed data. The method of making a request in the third embodiment is the same as that in the second embodiment or its modified example, and thus detailed description is omitted.

Upon receiving a request from a viewer (referred to as request data in this embodiment), the service providing unit 34 of the broadcasting device 30 performs a process of searching for stored data corresponding to the request data as shown in FIG. Perform (step S560). In this embodiment, it is assumed that the viewer has requested the event information of the area where the viewer is currently viewing.
Such event information is stored in the data storage unit 44 in advance.

The service providing unit 34 extracts corresponding event information and the like according to the data requested by the viewer, multiplexes the information into a broadcast signal, and transmits the multiplexed transmission information corresponding to the transmitter identification signal TII received from the viewer. A process of transmitting from the device 40 is performed (step S570). When the broadcast is performed using the multiplexed signal including the requested data, the receiver 50 receives the multiplexed signal, extracts the transmitter identification signal TII (step S600), and demodulates the audio signal. (Step S61
0). Further, the receiver 50 performs a process of extracting the multiplexed data from the multiplexed signal and displaying the data of the event in the transmission area on the display unit 66 (Step S62).
0).

That is, according to the third embodiment, the viewer is
By using a multiplex broadcasting system such as an AB broadcasting system, it is possible to obtain information on an event in a region where a viewer actually exists at any time. As information about the event, not only so-called events such as exhibitions and expositions held at that time but also local information such as restaurant introductions, gas station location information, traffic congestion information, etc. it can. For this reason, for example, when the viewer is on a moving object such as a car, it is possible to easily obtain the event or the local information of the destination using the broadcast system.

<Fourth Embodiment> Next, a fourth embodiment of the present invention will be described. In the first to third embodiments, the multiplexed and broadcast information is used as a part of a broadcast signal or as a part of multiplexed data, regardless of whether the broadcast device 30 Was prepared by the side. On the other hand, in this embodiment, information multiplexed and broadcast (hereinafter referred to as distribution information) is transmitted to the viewer side, that is, the receiver 50.
Prepared by the side. FIG. 14 is a flowchart showing the receiver processing routine and the broadcasting apparatus processing routine in this embodiment in association with each other.

In this embodiment, it is assumed that the viewer uses the receiver 50M mounted on the computer 80. That is, the viewer creates distribution information requesting distribution in advance using the computer 80. Such distribution information may be, for example, information on event holding or music produced by the viewer. In the case of music or the like, sampling is performed at a predetermined sampling rate and converted into digital data. At this time, MP3
It is also preferable to compress them by such a method.

When the receiver-side processing routine shown in FIG. 14 is started, first, the receiver 50M performs a process of specifying created distribution information (step S700), and then broadcasts the distribution information. A process for specifying an area is performed (step S710). The processing for specifying the area is shown in FIG.
As shown in the above, this can be done by selecting from several options. Here, if the "area where the receiver exists" is checked, the transmitter identification signal extracted from the multiplexed broadcast signal by the normal receiver 50M is used. When other areas, for example, "adjacent east area" are checked, the transmitter identification signals corresponding to those areas are used. Naturally, as shown in FIG. 16, the area where the receiver 50M is present and the area adjacent thereto are shown in a map, and the area on the map is clicked with the mouse 92 or the like to display the area to be broadcast. May be specified. In the example shown in FIG. 16, the area TE in which the receiver exists and the area NB1 adjacent thereto are selected. The transmitter identification signal corresponding to another area may be distributed in advance in the form of a CD-ROM or the like, or may be distributed using data multiplexed with a broadcast signal. May be used. Of course, the correspondence between the area and the transmitter identification signal may be received via the telephone network NT as a communication path.

When the distribution information and the regional information which is the information on the region to which the information is to be distributed are specified, the receiver 50M adds the request data for requesting the broadcast of the information to the information and transmits the information. The information is configured as a series of packets (step S720). Subsequently, a process of transmitting this series of packets from the mobile phone 72 to the broadcast device 30 via the base station 74 and the telephone network NT is performed (step S730).

The service providing unit 34 of the broadcasting device 30 that has received the transmission of the information executes the broadcasting device processing routine of FIG. 14, and first performs a process of receiving a series of packets output from the receiver 50M (step S800). ). Subsequently, the first data of the received packet is confirmed, and it is determined whether or not the received series of packets is a request for broadcasting (step S810). If it is determined that the broadcast is requested, then the contents of the packet are determined, and a process of extracting distribution information as information to be broadcast and area information indicating a broadcast area is performed (step S).
820). The area information to be broadcasted is set in advance by the receiver 50M.
Since it is converted to a transmitter identification signal, it may be simply extracted as a transmitter identification signal and stored in a memory or the like.

Next, information to be broadcast extracted from a series of packets is specified as data to be multiplexed, and a process of outputting the data to the modulation unit 33 is performed (step S830). At this time, a transmitter identification signal extracted and stored in advance is added. Therefore, the transmitting unit 31 that has received the information to be broadcast and the transmitter identification signal via the modulating unit 33 outputs these information only from the corresponding transmitters 40A, 40B,. Therefore, the process in step S830 is a process of multiplexing the broadcast information and transmitting the multiplexed broadcast information from the corresponding transmitter. In this way, when the broadcast is performed by the signal in which the data is multiplexed, the receiver 50 existing in the transmission area can extract the broadcast signal from the data, and only the viewer in the specified area can receive the broadcast signal. Event information and specific contents (for example, music compressed by MP3) can be received.

According to the fourth embodiment described above, the viewer can notify various information to the area where he / she resides or the area where he / she wants to broadcast by multiplexed data. As such information, various things can be considered, such as event information (for example, notification of flea market holding: date and time: place, etc.), requests for "sell and buy", and contents such as music itself. Conventionally, such information has been exchanged using a function such as a bulletin board of a personal computer communication. While personal computer communication is a so-called closed exchange only for those who subscribed to personal computer communication,
The system of this embodiment has a great advantage in that information can be provided as a system open to an unspecified number of broadcasters. As long as the receiver 50 has a function of extracting data from the multiplexed broadcast, there is a great advantage that such information can be received at any time. In addition, since such information is broadcast by specifying an area to be broadcast, for example, when the receiver 50 is mounted on a moving object such as an automobile, a viewer who moves across the transmission area cannot receive the information. It is preferable to receive information corresponding to

The information to be broadcast is not multiplexed and transmitted immediately upon receipt of the information, but is temporarily stored in the data storage unit 44 and transmitted in a broadcast time zone stored in advance by the broadcasting apparatus 30 side. It is also realistic to do it. Since a request from a viewer can be accepted at any time, the request may be broadcast at the same time as the request. However, for example, a time for the viewer may be provided, and the broadcast may be broadcasted in that time zone. If the information to be broadcast is content such as music, the service providing unit 34 reproduces the information as audio information, and
Can also be stored. In this case, instead of being multiplexed with the broadcast signal, it is also possible to broadcast as a part of the broadcast signal from the transmitter 40 in the designated area.

Although several embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and can be implemented in various modes without departing from the scope of the present invention. Of course. For example, in the above description, DAB broadcasting has been described as an example. However, the present invention can be similarly applied to broadcasting in other formats in which information on a transmission area and a location where a receiver exists, such as a transmitter identification signal, can be added or obtained. It is. Also, the telephone network was used to transfer response data from the receiver, but it is also realistic to transfer data from the receiver using a communication path such as the Internet, personal computer communication, or wireless transmission. It is.
