Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a bidirectional broadcasting system, a bidirectional broadcasting system, and a bidirectional broadcasting receiving apparatus.

[0002]

2. Description of the Related Art For example, in television broadcasting, television shopping, questionnaire surveys, quiz programs of viewer participation type, etc., on the television broadcasting side, the reception telephone number for the response is a supermarket only for an appropriate time. Conventionally, two-way broadcasting has been conventionally performed in which the response is displayed on the screen with an impose and the response from the viewer is made by telephone or facsimile.

However, in the conventional two-way broadcasting system or system, when the viewer makes a call to the reception telephone number in order to respond to the above-mentioned two-way broadcasting program, the line is congested and the telephone is called. There are problems that it is difficult to take, or that it takes a long time to give a verbal response, and the viewer's line usage fee increases accordingly, and the telephone line is overloaded.

In order to solve the problem of the telephone line at the time of responding to the two-way broadcast, a telephone company has recently provided a telephone voting service called so-called telegon.

In this telephone voting service, a telephone number for reception is assigned to each of a plurality of answers to one question in, for example, questionnaire surveys and quizzes on TV and radio programs, publications and the like. , The number of incoming calls to each telephone number, that is, the number of responses from viewers is counted and aggregated at each telephone station side of the calling side, and the number is notified to the broadcasting station side or the publisher side, This is a system that uses the existing telephone infrastructure.

[0006] The telephone voting service will be described with reference to a concrete example.
When broadcasting a questionnaire survey of a favorite baseball team, as shown on the television screen 1 of FIG. 26, a different response telephone number is set and broadcasted for each baseball team as a response option.

Each viewer 2 refers to the television screen 1 and dials the telephone number of the baseball team he / she prefers.

Then, the telegon system 3 receives an incoming call for each answering telephone number at the digital exchange of the subscriber exchange station in the area of the viewer, sends an automatic voice response message of acceptance completion notice to the responder, and Performs a primary count of the number of incoming calls for each answering telephone number. Then, the telegon system 3 collects the number of incoming calls primarily collected by the subscriber exchange stations all over the country at the service network control station, and further collects the collected data at the management station. The management station collects the total number of incoming calls for each answering telephone number from the call notification computer 4 of the television station 4 through the call number notification line 3a.
Notify a.

The television station 4 broadcasts a screen such as a graph of the aggregation result as shown in the television screen 5 of FIG. 26, for example, in order to reflect the aggregation result notified from the telegon system in the broadcast program.

In the telegon service, a request from a service contractor (broadcasting station 4 in this example), as shown in FIG.
In the example of 6, customer control computer 4b
In response to a request from the service provider, the call from any responder can be directly received by the service contractor (in this example, the operator 4c of the broadcasting station). This service is called cut-through, and the telegon system 3 sends a connection notice to the responder who is the cut-through. In this cut-through state, the responder is sent through the cut-through reception line 3c. Can directly call and exchange data with the service contractor. However, the number of lines for accepting this cut-through is limited in advance.

In the telephone voting service described above, the response from the responder is practically completed when the call arrives at the telephone station, and the line can be disconnected to reduce the load on the telephone line. In addition, the same charge can be applied regardless of where the call is made from anywhere in the country, and the viewer can go on-hook immediately after receiving a call, thus reducing the burden of line usage charges.

[0012] Further, since the incoming call is received at the subscriber exchange station and the total of the telephone votes is distributed for each region, congestion of the relay line can be avoided, and a relatively large number of calls are broadcast as the number of votes in a short time. You can notify the station side.

[0013]

However, in the current telephone voting service system, it is notified to the service contractor side such as the broadcasting station in the above-mentioned example that the voting according to the option for each question is sporadic. It is a number, and the service contractor cannot obtain a response (vote) that associates a plurality of questions. For example, you want to respond to a series of quizzes in a winning (losing) manner, or by responding to a questionnaire by a telephone voting service in advance, for example, to narrow down the responders, such as requesting only men over a certain age to respond. However, it is not possible to restrict response access from those who do not meet the conditions, and it is not possible to check whether the responders meet the conditions.

Although it is possible to enhance the processing function of the subscriber exchange on the side of the telephone station so as to perform the voting result and the selection processing of the response in which a plurality of questions described above are associated, a call is made in a short time. However, if the conventional subscriber exchanges are used, it cannot be realized. Therefore, it is necessary to improve the subscriber switching offices. However, considering the cost, it is realistic to upgrade more than 7,000 subscriber switching offices nationwide only to enhance the function of the telegon service. is not.

[0015] As one form of interactive programs for television and radio, there is a case where a premium type broadcast program, that is, some prize or merchandise is provided to a responder. In this type of program, it is necessary to identify the responder, but in the conventional telegon system, the incoming call is made at the subscriber exchange station, and at that point it is simply counted as one vote, so the broadcast station The respondent cannot be identified on the side.

Even in the above-described conventional telegon system, the responder can be specified on the broadcast station side by using cut-through. However, whether to use cut-through depends on the selection reflecting the voting result. Since it is not done in response, it is not possible to cut through only the respondents who voted for a specific option. For this reason, it has been practically impossible to broadcast the above-mentioned premium type broadcast program in a form using the telephone voting service.

On the other hand, the response of the premium type broadcast program is
It is possible to identify the responder by forming a communication path from the responder's terminal to the terminal on the broadcasting station side. However, in that case, as described above, whether or not access from all responders can be processed without congestion becomes a problem.

In view of the above points, the present invention is capable of performing a broadcast in which a plurality of questions are associated with each other, even when the response to the interactive program is performed using the current telephone voting service. The purpose is to enable narrowing down of numbers.

Another object of the present invention is to enable the broadcasting station side to reliably identify the responder of the response to the interactive program.

[0020]

In order to solve the above-mentioned problems, the two-way broadcasting system according to the present invention broadcasts a question, a choice of a response to the question, and a response destination telephone number for each choice, and makes a response. wherein in the two-way broadcasting system so as to obtain the incoming number information of the response of each choice, and evaluation information for evaluation of the response at the receiver for one or more questions, evaluation results based on the previous SL evaluation information from persons And the selection information for selecting whether or not the responder is a respondable person, and repeating the broadcast of the question, the evaluation information, and the selection information one or more times. Thus, the number of respondable persons is narrowed down.

Further, the interactive broadcast receiving apparatus according to the present invention includes a broadcast program providing unit 21 for receiving a broadcast signal and providing an interactive broadcast program to a user when the reference symbols of the embodiments described later are associated with each other. , A decoding unit 217 for extracting and decoding interactive program information multiplexed in the broadcast signal, a communication interface for making a response to the interactive program via a telephone line, and a user's response operation to the interactive program Key input operation unit 23 for performing a response operation, a response execution unit 305 for performing a response in response to a response operation, a unit for storing a history of response operations in a storage unit 307, and multiplexing obtained from the decoding unit. When the multiplexed signal is the evaluation data, the signal is discriminated and the response operation history stored in the storage unit 307 is compared with the evaluation data to evaluate the response. 0 and the multiplexed signal obtained from the decoding unit are discriminated, and when the multiplexed signal is the selection data, the own device is selected based on the evaluation result by the evaluation means 310 and the selection data. When it is judged whether or not it is out of the selection, the judgment means 312 controls the response execution unit so as to limit the response through the telephone line regardless of the subsequent response operation by the user.

In the bidirectional broadcasting system according to the present invention having the above-described structure, the receiving device that has responded to the broadcast of the question from the broadcasting station stores the response history in the storage means. When the broadcasting station broadcasts the evaluation data, it evaluates the response made by itself based on the evaluation data. Furthermore, when the selection data is broadcast from the broadcasting station side, the selection data is used as a basis for determining whether or not the own device is a person who can be a responder to a subsequent question, based on the evaluation result of the response. When it is determined that the own device is a person who cannot respond to subsequent questions, the receiving device
By itself, it is limited so as to prohibit to perform a call subsequent response.

As a result, the number of respondents to the next question is automatically narrowed down. That is, even when the telephone voting service such as the telegon service is used for the response of the interactive program, it is possible to broadcast a plurality of questions for which a response associated with the previously broadcast question is expected.

Even when the telephone voting service is used for the response of the interactive program as described above, the number of responders can be narrowed down. Such as offering products and prizes to responders,
It becomes possible to broadcast so-called premium interactive programs.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a bidirectional broadcasting system and its receiving apparatus according to the present invention will be described below. This embodiment is an example of the case of television broadcasting, and in this example, the broadcasting station side broadcasts the question and its options as a broadcast program, and at the same time, the question number, the option number and the response destination telephone number. Program related information as sub-broadcast information such as question data including, etc., evaluation data for evaluating the question, selection data for selecting respondents from the evaluation result, and the like are multiplexed and broadcasted on a broadcast signal. .

Then, in this example, the program-related information is sent to the DTM.
The signal of the F signal format is multiplexed (mixed) with the main broadcast audio signal and broadcast. On the other hand, on the receiving side, the DTMF signal is separated / decoded from the received broadcast sound, the program-related information is reproduced, stored in the memory, and used when responding to the interactive program.

Further, in this example, the above-mentioned telephone voting service (telegong service) is used for the response to the interactive program.

[DTMF Signal] First, the DTMF signal will be described with reference to FIG. The DTMF signaling system has one low frequency group (low group) and another one
One is an audio band signaling system that simultaneously sends two tones of a high frequency group (high group). Each of these low and high frequency groups consists of tones of four audio band frequencies, no two of which are in articulatory relation.

In the DTMF signal, the four frequencies in the low group are, for example, 697 Hz, 770 Hz, 852 Hz, 941H.
z, and the four frequencies of the high group are, for example, 1209 Hz,
It is set to 1336 Hz, 1477 Hz, and 1633 Hz. Then, each of the low group and the high group is combined with one frequency, and each DTMF composed of the combination is combined.
Signals (each of these DTMF signals are hereinafter referred to as function signals) are assigned to push buttons "0" to "D" arranged in 4 rows and 4 columns, as shown in FIG.

In the telephone communication, only 12 of the 16 functional signals of the DTMF signal are generally used for the subscriber address (telephone number) signal. That is,
"0" used as a so-called numeric keypad on the telephone
The function signals of the above 12 combinations correspond to the numbers "9" and the symbols "*" and "#". Figure 2
The function signals corresponding to the letters "A", "B", "C", and "D" indicated by broken lines in Fig. 3 are not generally used in Japan, but data using the push button (PB) dial. It is only used for transmission.

When a line is selected by a telephone number using such a DTMF signal, the signal transmission conditions are as shown in FIG.
It is prescribed as shown in.

Due to the combination of the two frequencies and the transmission conditions as described above, the DTMF signal rarely occurs in the natural world and can be clearly distinguished from natural sounds such as human voice. It is possible to multiplex (mix) the broadcast audio signal and broadcast it, and separation on the receiving side is relatively easy.

By the way, the DTMF signal is also used in a multi-function telephone, and by operating a push button type telephone from outside the house, the message recorded on the telephone at home can be played back or the answering machine can be recorded. You can record, play back, and delete the message.

[Outline of Bidirectional Broadcast System] FIG. 1 shows an outline of the bidirectional broadcast system of this embodiment. The bidirectional broadcast system of this example is a system 10 of a broadcasting station and a receiver system. 20 and a central office system 30 including a telegon system 33.

In the system 10 of the broadcasting station, 11 is a studio of the broadcasting station, and the interactive program created here is transmitted from the broadcasting antenna 12 to the receiving device system 20 by a terrestrial wave or via an artificial satellite 13. To be done.
For example, in the case of interactive programs such as quiz programs and questionnaire surveys, questions and a plurality of options for each question are broadcast on the screen of the television receiver or by an announcement by the moderator of the program. Questions are usually
One or more will be broadcast. At this time, the interactive program related information has a format of DTMF, which will be described later.
It is multiplexed with the broadcast audio signal in the form of a signal.

The receiving device system 20 comprises an existing television receiver 21 and an adapter device 25 for receiving and responding to interactive program information. The adapter device 25 comprises an adapter device body 22 and a remote commander 23 using infrared rays, and an external telephone 24 can be connected to the adapter device body 22.

The adapter device main body 22 has a receiving unit and a decoding unit for the infrared remote control signal of the remote commander 23. As shown in FIG. 4, the adapter device main body 22 can accommodate the remote commander 23 such that the infrared light emitting portion 23SD thereof faces the infrared light receiving portion 22PD. That is, as shown in FIG. 3, the adapter device body 22 is provided with a recess 22R for accommodating the remote commander 23.
The remote commander 23 is simply housed in the recess 22R to give the appearance shown in FIG.

As shown in FIG. 4, when the remote commander 23 is housed in the adapter device main body 23 and the various buttons 23a, 23b, 23K of the remote commander 23 are operated, a remote control signal corresponding to the operation is emitted. Part 2
Adapter device main body 22 via 3SD and light receiving unit 22PD
Since it is sent to and decoded by the device, it is used as if it operates as an adapter for receiving and responding to one piece of interactive program information.

As will be described later in detail, the adapter device main body 22 is an NCU as an interface with a telephone line.
(Network control unit)
As shown in FIG. 1, a telephone line 31 and an external telephone 24 are connected to the adapter device body 22. In this example, the external telephone 24 can access the telephone line 31 via the adapter device main body 22 and can perform a normal telephone function.

As will be described later, the adapter device main body 22 and the remote commander 23 also have a so-called hands-free telephone function. That is, as shown in FIGS. 4 and 5, the remote commander 23 includes an on-hook button 23 a and an off-hook button 23.
b is provided, and a so-called ten-key (numeric etc.) button 23K is provided. On the other hand, the adapter device main body 22 includes a microphone 22MC and a speaker 22SP.
Is provided.

When making a call as a hands-free telephone, the off-hook button 23b is pressed and the telephone number is dialed by the ten-key button 23K. Further, it is only necessary to press the off-hook button 23b for an incoming call from the other party. When talking to the other party, the transmitted voice from this is the microphone 22M.
The voice received from the other party is sent through the speaker 22
Try to listen from the SP. Then, when the talk with the other party is finished, the line can be opened by pressing the on-hook button 23a.

The adapter device main body 22 also functions as a reception / decoder for interactive program information that is multiplexed and broadcast as a DTMF signal, and also functions as an interactive program response device in cooperation with the remote commander 23.

That is, in this example, the interactive program information is
Since the DTMF sound is mixed with the broadcast program sound and is emitted from the speaker 21SP of the television receiver 21,
As shown in FIGS. 1 and 6, the adapter device body 22 picks up a sound emitted from the speaker 21SP of the television receiver 21 with the microphone 22MC. As will be described later, the adapter device main body 22 outputs D from the collected sound.
It has a function of extracting only TMF sound and decoding the interactive program information. Of the decoded interactive program information, the adapter device body 22 also includes information necessary for a response,
Since the telephone voting service is used in this example, at least the function of storing a response destination telephone number (telephone service telephone number) for each question option in the memory built in the adapter device body 22 is provided.

The response operation to the question in this example is
It is an option number selected by the user (responder) from a plurality of options preset and broadcasted for the question, which is input by operating the ten-key button 23K of the remote commander 23. In this example, in the state of FIG. 4 or the state of FIG. 6, when the option number is selected as the answer to the question with the ten-key button 23K of the remote commander 23, the adapter device main body 22 The remote control signal is received, the question number that is the target of the response operation and the selected option number are stored in the response history memory, and the telephone number associated with the selected option number is read from the memory. , Automatically dial the phone number.

As shown in FIG. 1, the digital exchange 32 of the telephone station accepts this incoming call and counts the number of incoming calls for each incoming call to the same telephone number. Then, each digital exchange 32 notifies the telegon system 33 of the number of incoming calls to each telephone number counted by the digital exchange.
The telegon system 33 is shown as one that performs the data collection and totalization function of the service network control station and management station described above.

In this way, in the telegon system 33, the total number of incoming calls for each option selected is notified to the computer in the studio of the broadcasting station through the telephone line 31 as the number of responders selecting the option. Broadcasting station
The result of this aggregation is broadcast to users in an interactive broadcast program.

After that, the system 10 of the broadcasting station multiplexes the evaluation data for the question into the broadcast sound in the form of the DTMF signal and broadcasts it. Upon receiving this evaluation data, the adapter device main body 22 compares the question number and the selected option number stored in the response history memory with the evaluation data, as will be described later, and makes a selection for evaluation on the broadcast side. Whether it was, if it is a quiz program,
Evaluate whether or not the correct answer is returned.

Subsequently, the system 10 of the broadcasting station multiplexes the selection data for the evaluation result into the broadcast sound in the form of the DTMF signal and broadcasts it. The adapter device body 22 evaluates the evaluation result based on this selection data. For example,
When the selection data requires that the number of correct answers for a question is a predetermined number or more, the selection is performed depending on whether or not the condition is met. In the case of omission in the selection, the adapter device main body 22 limits the response so as to prohibit the response to the question broadcast thereafter, for example. Therefore, even if the user of the adapter device main body 22 in the response limited state responds to a question broadcast thereafter, it is not called.

In this way, the originator of the response self-limits the origination of the response. Therefore, even in a system that responds to an interactive program by using a telephone voting service such as telegon, a so-called win-win quiz program or a premium type program is used. It becomes possible to provide the two-way broadcasting program of.

[Broadcasting of interactive program from broadcasting station] As described above, in this example, the television broadcasting station broadcasts the question and the choices of the response to the question.
The contents of the question and the contents of a plurality of options for the question are notified to the viewer (responder) by the screen of the television receiver or the announcement of the program host. At the same time, the numbers [0] to [9] are multiplexed on the broadcast signal,
The interactive program related information in which a combination of symbols [#] [*] and [A] [B] [C] [D] is expressed by a DTMF signal is broadcast.

In this example, the program-related information is mainly
It consists of question data, evaluation data, selection data, and (selection + ID request) data. The data to be multiplexed is
In addition, it includes response control data such as response start, response end, and call restriction release.

FIGS. 7, 8, 9, and 10 respectively show
The example of the data structure of question data, evaluation data, selection data, and (selection + ID request) data is shown. A packet identification code for identifying each of these data is added to the beginning and a packet end code is added to the end of the data, and the data length is variable. In this example, the packet end code is [DD] and the symbol [D].
Of the DTMF signal that represents two times.

[1. Question Data] FIG. 7 shows an example of the data structure of the question data. That is, the question number follows the first packet identification code. Behind the question number, option data for each of the plurality of options broadcast in the broadcast program for the question with the question number is inserted. A symbol [*], which is a separator (separation mark), is inserted between each option data.

In the case of this example, each option data includes the option number (option number) and the response destination telephone number (telephone service telephone number) assigned to the option.
Composed of and. In the case of this example, up to 100 options can be set for one question, and therefore the option number is any one of [00] to [99]. The option number may of course be a skip number instead of a continuous number. Also, the response destination telephone number in the case of this example is [01800xxxxxx].

Regarding the answering telephone number, it is possible to reduce the amount of data to be multi-broadcast by performing the following instead of broadcasting all the 10-digit telephone numbers.

That is, the first method broadcasts all 10-digit telephone numbers as the response destination telephone numbers of the first option data broadcast as the question data. Then, the response destination telephone number of the subsequent option data broadcasts the difference from the response destination telephone number of the first option data or the difference from the response destination telephone number of the immediately preceding option data.

For example, as the response destination telephone number of the option data for the four options of the serial numbers [01] to [04], a method of broadcasting the difference from the response destination telephone number of the immediately preceding option data is adopted. In some cases, it can be as shown in FIG. 11A. That is, in the case of the example in FIG. 11A, [0180000001] and all 10-digit numbers are sent as the response destination telephone numbers of the first option number [01], and the subsequent option numbers [02] to [04].
As the information of the telephone number to be responded to for each of the options,
This is the case where only [1] is sent as the difference.

In the case of this example, on the receiving device side, the response destination telephone number of the first option number [01] is [0
180000001], and the subsequent option number [0
The answer destination telephone numbers of the respective options 2] to [04] are sequentially incremented by the difference [1] to the number [0180000001].
The numbers [0180000002] and [0180]
[00000003] and [0180000004].

If the number of options is 10 or less, the option number for multiple broadcasting may be one digit. If the difference to be added is set to a predetermined fixed value, this difference information is
There is no need to multiplex and broadcast.

In the example of FIG. 11B, the serial numbers [01] to [0]
4] is an example in which a method of broadcasting the difference from the response destination telephone number of the first option data is used as the response destination telephone number of the option data for the four options.
Also in the case of this example, if the difference is a predetermined fixed value, multiple broadcast of the difference is unnecessary.

As a second method of compressing the telephone number information, as described above, the telephone number of the telegon service is determined to have the upper four digits as [0180], and the service is used in the broadcasting medium. In this case, the fact that the next digit is also set to [0] is used.

That is, in the case of this second method, the fixed upper five digit telephone number is not sent. In the case of this example, since the number of question data is 100 or less, it is changed by the lower two digits and the upper three digits are the same number, which is represented by a one-digit number. That is, for example, [018001101] can be represented by [1] when [111] is represented by [1], and information of the telephone number can be represented by [101]. For example, [0180022203] is [2
22] is represented by [2], the telephone number information is [20
3]. An example of the plurality of option data in the case of this example is shown in FIG. 11C.

Further, as described above, the number [018000
[0180000002] and [0180000000] for sequentially adding the difference [1] with [0001] as the initial value
3], [0180000004] ... When the telephone number represented by zero suppression on the right side is used as the vote number (answer telephone number), the first telephone number [0180000001] is set as [1]. It is possible to represent multiplex broadcasts and sequentially multiplex the difference [1]. In this case, if the difference is set to a predetermined fixed value as described above, only the data [1] for the first telephone number is multiplexed and there is no need to multiplex and broadcast the difference data. It is possible to multiplex broadcast telephone number information with a small amount of information.

Next, in the case of this example, the question data is
Two types of question data are defined according to the number of questions.
That is, in the case of question data in which the number of questions is 10 or less, the packet identification code is "B" and the question numbers are represented by [0] to [9]. In the case of question data in which the number of questions exceeds 10, the packet identification code is set to "C" and the question numbers are [00] to.
It is represented by [99]. That is, when the number of questions is 10 or less, the question data of the packet identification code [B] is broadcast, and when the number of questions exceeds 10, the question data of the packet identification code [C] is broadcast. Become.

In the question data, check data for error detection is broadcast after the separator [*] after the plurality of option data. This check data is error detection data for all option data, and an error detection method such as checksum can be used.

After the check data, information on the response permission time range is broadcast. In the case of this example, 0 to 9 minutes can be set as the response permission time range. The question data ends with the information of the response permission time range, and the packet end code [DD] is broadcast last.

[2. Evaluation Data] FIG. 8 shows an example of the data structure of the evaluation data. The packet identification code of the evaluation data is assigned the symbol [D] in this example. After the evaluation data identification code [D], information on the number of evaluation data is broadcast. The number of evaluation data corresponds to the number of questions and is a numerical value between [00] and [99]. Next to the information on the number of evaluation data, evaluation data ES1 to ESn (n is a natural number) for each question 1 to n are broadcast. Here, the number next to the symbol ES corresponds to the question number. Each of the evaluation data ES1, ES2, ...
One option number of a plurality of options set for each question is broadcast. For example, in the case of quiz,
It is the correct option number.

After the evaluation data ES1 to ESn, the evaluation data ES is processed in the same manner as the question data.
Check data such as a checksum for error detection for 1 to ESn is broadcast. After the check data, the packet end code [DD] is broadcast last.

The evaluation data in the example of FIG. 8 is an example in which the number of choices, which is the evaluation data for one question, is one. However, by dividing the evaluation data for each question with a separator [*], a plurality of items can be obtained. It is also possible to collectively broadcast a plurality of option numbers as evaluation data for each question.

[3. Selected Data] FIG. 9 shows an example of the data structure of the selected data. The packet identification code of the selection data is assigned the symbol [AB] in this example. After the selection data identification code [AB], the selection type code is broadcast. In this example, since three types of selection type codes are prepared, three types of selection type codes of [0], [1], and [2] are prepared in this example. Then, after the selection type code, the selection data SEL is broadcast, after that, the check data and finally the packet end code [DD] are broadcast.

In this example, three types of selection codes are prepared. When the classification type code is [0], the classification is performed by giving the minimum number of questions that must be answered correctly among the provided multiple questions. Data SEL
Is the minimum number of questions that must be answered correctly (allowable number of correct answers), and is represented by a two-digit number between [00] and [99] or [**]. When the selection data SEL is [**], it means that all are selected.

When the selection type code is [1], it is selection data for the question data within 10 questions broadcast by the packet identification code [B], and a plurality of question numbers for which correct answers are indispensable are provided as selection data SEL. Individually broadcast. In this case, the correct answer question numbers are [0]-
It is a one-digit number in [9].

When the selection type code is [2], it is the selection data for the question data of the eleventh or more questions broadcast by the packet identification code [C], and similarly, the question number for which the correct answer is essential is selected. A plurality of data SELs are broadcast. In this case, the correct answer required question number is a two-digit numerical value of [00] to [99].

[4. Selection + ID Request Data] FIG. 10 shows an example of the data structure of (selection + ID request) data. The packet identification code of this (selection + ID request) data is assigned the symbol [BB] in this example. This (selection + ID request) data is shown in FIG.
As can be seen from the above, except that the packet identification code is different, it has the same data structure as the selection data.

The difference from the selection data is that (selection + I
D request) data is a point that requests the responder side to send its identification information to the broadcasting station side. As will be described later, when the responder side receiving device receives this (selection + ID request) data, if the response is not limited, the receiving device identification information or the responder identification information is broadcast over the telephone line. Send to the side.

[Broadcasting procedure of interactive program related information] FIG.
And FIG. 13 is a flowchart of a procedure on the broadcast station side for broadcasting interactive program-related information. It should be noted that the double-framed frame shows the broadcast in-program broadcast performed by the broadcast station accompanying the broadcast of the interactive program-related information, and other operations. FIG. 14 shows the flow of question data, evaluation data, selection data, (selection + ID request) data, and the like, which are program-related information sent at this time.

As shown in FIG. 12, in order to start accepting the response on the broadcast station side, first, control data for starting the response is broadcast (step 101). In this example, the response start control data is [AA] as shown in FIG.
And a DTMF signal representing the symbol [A] continues twice.

After that, when the question is broadcast (S1) in the program viewed on the television receiver, the question data concerning the question broadcast in the program is multiplexed and broadcast as a DTMF signal in the broadcast signal. (Step 10
2). For this question, there was a response from the viewer within the response time range described above, and the number of incoming calls (votes) to the telephone number for each of the multiple options for the question.
However, since the telegon system of the telephone station notifies the broadcasting station as a voting result, the broadcasting station receives the voting result (S2). Then, the broadcasting station broadcasts the voting result in the program, as shown in FIG. 23 (S3).

Then, the above processing is repeated until the broadcasting of the predetermined number of questions which has been scheduled as a program program in advance is completed (step 103). When the predetermined number of questions have been broadcast, the response end is broadcast within the broadcast program (S
4).

Thereafter, the evaluation data for each of the broadcasted plurality of questions is multiplexed and broadcast as a DTMF signal in the broadcast signal (step 104). Next to the evaluation data, selection data for performing selection based on the evaluation result is broadcast (step 105).

From these evaluation data and selection data,
As will be described later in detail, on the receiving device side, it is determined whether or not each receiving device can be a responder who can respond to subsequent questions. Then, the receiving device that fails to sort out limits (for example, prohibits) subsequent responses.

On the broadcast station side, the next question is broadcast in the program (S5). Therefore, the question data for the question is multiplexed as a DTMF signal on the broadcast signal and broadcast (step 106).

For this question, there is a response from the viewer whose call origination is not restricted by the above-mentioned receiving device within the response allowable time range specified by the question data. Then, the number of incoming telephone numbers (votes) for each of the plurality of options for the question is notified from the telegon system of the telephone station to the broadcasting station as a voting result. It is received (S6).
Then, the broadcasting station broadcasts the voting result in the program, as shown in FIG. 23 (S7).

Then, it is judged whether or not the total number of votes notified from the telephone office is within the range of the allowable number of calls by the number of telephone lines prepared as a cut-through for telegon (step 107), and the total votes are given. If the number is not within the allowable number of outgoing calls, return to step 104,
Regarding the question broadcast in S5, evaluation data and selection data are broadcast in response to the response made based on the question data broadcast in the previous step 106 (steps 104, 10).
5) After narrowing down the respondable persons, the next question is broadcast (S5) and question data is broadcast (step 106).

When the total number of votes from the respondents is within the allowable number of outgoing calls in step 107, the process proceeds to step 108, and the evaluation data on the response to the previous question is broadcast. Next, in step 109, (selection + ID request) data is broadcast. On the other hand, on the receiving device side, the previous response is evaluated based on the received evaluation data, and selection is performed.

After that, since the next question is broadcast in the broadcast program (S8), the question data for the question is broadcast (step 110). Those who can respond to this question respond. At this time, the receiving device and the broadcasting station side are directly connected by a telephone line by cut-through,
A response is made, and together with the response data, the identification information of the responder side (identification information of the receiving device or identification information of the responder) is sent to the broadcasting station side, and the broadcasting station side receives these (step 111). . At this time, the broadcast station side can identify each responder by the identification information of the responder side.

Next, the routine proceeds to step 112, the number of responders to broadcast the questions (S8) determines whether the last sorting the planned number of planned in advance broadcasting station, otherwise For example, go to step 108 to broadcast the evaluation data,
(Selection + ID request) Data broadcasting (steps 108, 1)
09) is performed again to further narrow down the responders. After that, further question broadcasting (S8), question data broadcasting for the question (step 110),
The response data from the possible responders and the identification information on the responder side are received (step 111).

When the number of respondents to the question is within the final planned selection number in step 112, the process proceeds to step 113, information for releasing the call restriction on the receiving device side is broadcast, and the end of response is broadcast ( Step 114). In the case of this example, as for the information of call restriction release, as shown in FIG. 14, the DTMF sound of the symbol [AB #] is multiplexed and broadcast with the broadcast sound. As the response end information, the DTMF sound of the symbol [AD] is multiplexed with the broadcast sound and broadcast.

When the receiving side receives the information on the cancellation of the call restriction, the call restriction has been cleared, and the restriction can be cleared and a new question can be answered from the beginning. And when the information of the end of the response is received,
The history of responses up to that point is also cleared. The response history may be cleared when the information for releasing the call restriction is received. However, with that, it is not possible to provide a so-called loser revival program that temporarily releases the call restriction. Therefore, as in this example, after receiving the response end information, the receiving side displays the response history. It is better to clear it.

In this way, by broadcasting the question, and by repeating the broadcasting of the question data including the information of the telephone number of the respondent regarding the question, the broadcasting of the evaluation data of the response, and the broadcasting of the selection data, the respondents can be narrowed down. It can be performed.

Then, by narrowing down the responders,
In a state where it is possible to avoid a so-called punctured state of the telephone line, the request for transmitting the identification information is multiplexed to the broadcast signal and broadcast to the responder side. In order to connect the receiving device side and the broadcasting station side directly through the telephone line, along with the response data,
The identification information of the responder can be sent to the broadcasting station.

That is, a telephone voting service such as Telegon is used to narrow down the responders, and then,
The responders narrowed down can be recognized on the broadcast station side. Therefore, it becomes possible to provide the premium interactive program by using the telephone voting service. Further, by using a questionnaire-type question, it is possible to easily narrow down the respondents such as limiting the respondents to only men, women, or viewers of a specific age group.

When the incoming call from the other party is received by the adapter device as a hands-free telephone, the user presses the off-hook button 23b. When the adapter device body 22 receives the remote control signal of the off-hook button 23b from the remote commander 23, the adapter device body 22 closes the DC loop and makes the call possible. After that, it is almost the same as when making a call. As described above, the adapter device can be used as a hands-free telephone.

[Reception and response of interactive program related information]
When receiving and extracting the DTMF sound from the sound output from the speaker of the television receiver, the adapter device main body 22
The microphone 22MC of is directed toward the speaker of the television receiver 21.

When the on-hook button 23a or the off-hook button 23b is not operated, the switch circuit 216 is switched to the microphone amplifier 214 side, so that the DTMF receiver 217 is included in the sound output from the speaker of this television receiver. Extract DTMF sounds. The decoded signal of the DTMF signal from the DTMF receiver 217 is supplied to the microcomputer 300.

FIG. 16 shows the DTM of this microcomputer 300.
It is a functional block diagram of a processing function of F signal. Microcomputer 3
In 00, when the other extraction means 316 receives the response start of [AA], the adapter device main body 22 is shifted from the standby state to the receivable state of various packet data for the response. Further, the response execution unit 305 is notified that the response operation can be accepted, and the memory and other necessary initializations are performed.

The other extraction means 316 uses [AD].
When the end of response is received, the adapter device main body 22 is set to a state in which various packet data for response (hereinafter,
The response execution means 305 is notified of the shift to the standby state from the simple receivable state).
Upon receiving the notification of the end of the response, the response executing means 305
No longer accepts subsequent response operations. further,
When the response restriction release of [AB #] is received, the response execution means 305 is notified of it. In response to this, the response execution means 305 releases the response call restriction if the response call restriction is applied by then.

In the receivable state, the microcomputer 300 extracts the question data, the evaluation data, the selection data, and the (selection + ID request) data, which are the interactive program related information, and executes the following processing.

That is, the question data extraction means 301
Question data is extracted from the decoded signal of the DTMF signal from the DTMF receiver 217, and the question number, the option number, and the corresponding response destination telephone number are stored in the memory 302. The notification of completion of registration in the memory 302 is sent by the response execution means 3
It is sent to the display control means 308 via 05. The display control unit 308 turns on the light emitting element 22LDb to notify the user that the data for the response has been decoded and fetched.

After confirming that the light emitting element 22LDb is turned on, the user (responder) performs a response operation using the key input operation unit 303. This response operation is an operation of inputting the number of one of the plurality of choices given to the broadcasted question or a plurality of required choices. This is done with the button 23K of the remote commander 23. In response to this response operation, response operation determination means 304
Determines the response operation. Practically, the microcomputer 300 takes in a remote control signal from the remote commander 23 via the light receiving unit 22PD and makes a determination.

The data of the option number as a result of the judgment is sent to the response execution means 305. The response executing means 305 refers to the memory 302, reads out the response destination telephone number assigned to the option number of the question, and automatically dials by the NCU unit 306 to issue a response. At this time, the response execution means 305 sends the option number selected by the user and the telephone number information of automatic dialing to the display control means 308. The display control means 308 displays the selected option number and the response destination telephone number on the display element 22LDa.

At this time, the response execution means 305 again
The time from when the question data was obtained is measured, and it is also determined whether or not a response operation is performed by the user within the response permission time range in the question data. When the response operation is performed when the response permission time range is exceeded, the alarm buzzer 315 (in FIG. 15, the buzzer 21
Drive 9) to let the user know that there is a response error.

When a response is called,
The response history is written in the response history memory 307. As the response history information, for example, the question number of the response target and the option number input by the response operation are stored.

In this way, the respondent can respond to each question by simply selecting the option number and operating the button.
It is not necessary to operate the off-hook button 23b. Then, in this example, the response uses the telephone voting service, which ends when the call to the subscriber exchange of the telephone station is completed, and the minimum call charge is required. In addition, from the telephone office, the user (responder) will be notified of the completion of reception by voice
This allows the user to know the end of the response. The adapter device main body 22 may be automatically put into an on-hook (line open) state in response to a line disconnection on the central office side, or on-hook after confirming an incoming call to the central office without receiving the reception completion notification. You may make it a state.

When the response permission time for the above question elapses, as described above, the telephone station notifies the broadcasting station of the number of incoming responses for each option, so that the broadcasting station multiplexes the broadcast signal for evaluation. Data is sent. Since this is mixed with the broadcast sound and emitted from the speaker of the television receiver, it is picked up by the microphone 22MC of the adapter main body 22 and decoded by the DTMF receiver 217. Then, in the evaluation data extraction means 309,
This evaluation data is extracted and decoded, and the evaluation means 3
At 10, the evaluation data is sent.

The evaluation means 310 compares the received evaluation data with the information of the response history in the response history memory 307, evaluates the response, and sends the evaluation result to the determination means 312.

Next, since the selection data is sent by being multiplexed with the broadcast signal, the DTMF signal is decoded by the DTMF receiver 217 and the selection data is extracted and decoded by the selection data extracting means 311 in the same manner as described above. It
Then, the decoded selection data is the determination means 31.
Sent to 2.

The judging means 312 judges from the evaluation result sent from the evaluating means 310 and the selection data whether or not the user of the adapter device body 22 is selected as a responder to the next question. Then, the result of the determination is sent to the response executing means 305.

Upon receipt of this determination result, the response execution means 305 limits the calling of subsequent responses when the user of the own device is not selected from the respondable persons, and prohibits calling in this example. Then, the response execution means 305 displays the information indicating that the calling restriction state is present in the display control means 3.
08, the display is displayed on the display element 22LDa, and at the same time, the alarm buzzer 315 is driven to notify the user that the call restriction state has been entered.

As a result of the judgment by the response execution means 305, when the user of the own device is selected as a respondable person,
Wait for the arrival of question data for the next question and the operation of responding to that question. Then, the adapter device main body 22
Performs the processing from the arrival of the next question data to the response operation of the user to the question in the same manner as described above.

Then, the evaluation data for the question to be broadcast thereafter is processed in the same manner as described above, and whether or not the user of the own device is further selected as the respondent to the next question by the selection data received subsequently. If it is judged that the user of the own device is not selected from the respondents, the subsequent calling of the response is restricted, and if selected, the arrival of further question data and the operation of the response to the question are waited for. . Then, the adapter device main body 22 performs the processing from the arrival of the next question data to the response operation of the user to the question in the same manner as described above.

The evaluation data for the question broadcast thereafter is processed in the same manner as described above. Then, when it is the (selection + ID request) data that is subsequently broadcast and received, the (selection + ID request) data extraction means 313.
Then, the data is extracted and decoded, and the selected data portion is sent to the judging means 312. In the same manner as described above, the determination unit 312 refers to the evaluation result data from the evaluation unit 310, determines whether the user of the own device is selected as a respondent to the next question, and displays the determination result. It is sent to the response execution means 305.

(Selection + ID request) Data extraction means 313
Also sends an ID sending request to the response executing means 305.
The response execution unit 305 responds to the ID transmission request when the user of the own device is selected as a responder.
When responding to the next question, the ID (identification information) of the adapter device body or the user ID is read from the ID memory (memory 218 in FIG. 15), and the ID is sent to the broadcasting station side together with the response information. In addition, from the broadcasting station side,
When this (selection + ID request) data is sent, the response is cut-through, so the information and ID of the response from the user are sent directly to the broadcasting station side via the telephone line. Sent to.

In the functional block diagram of FIG. 16, the selection data extracting unit 311 and the (selection + ID request) data extracting unit 313 are separate blocks, but both blocks are extracted by one block to extract the selection data. Is the judging means 31
It is also possible to send to the response execution means 305 when there is an ID request.

Then, when the call restriction release information is sent from the broadcasting station side, the call extraction restriction release information is extracted and detected by the other extraction means 316 of the adapter device main body 22, and is issued by the response execution means 305. When the call restriction is applied, it is released. Therefore, even if the call restriction is once applied, it can be easily canceled according to the content of the program broadcast from the broadcasting station, and interactive programs in various modes can be provided. Before the broadcast of the end of the response of the interactive program, the calling restriction release information is normally broadcast from the broadcasting station side to clear the adapter device body 22.

As described above, the response to the interactive program is performed. Next, the microcomputer 3 for this response processing
The processing flow of No. 00 will be described below with reference to FIGS.

In the standby state, the microcomputer 300 checks the DTMF receiver 217 whether a DTMF sound is detected or not, for example, at regular intervals (step 401).

In step 401, the DTMF sound is converted to DTMF.
When detected by the receiver 217, the DTMF signal is decoded (step 402) to determine whether it is a data packet of question data, evaluation data, selection data, etc., or interactive program information such as response start, response end, call restriction release, etc. It is determined whether or not (step 403). If it is not the interactive program information, the process returns to step 401. If the result of the determination in step 403 is interactive program information,
After performing the processing subsequent to FIGS. 19 to 20, step 4
Return to 01.

In step 401, the DTMF sound is set to D
When it is determined that the TMF receiver 217 has not detected it, the process proceeds to step 404, and it is determined whether the response start information has been received and is in the receivable state. If it is not in the receivable state, the process returns to step 401, and if it is in the receivable state, the process proceeds to step 405 to determine whether or not the remote control signal from the remote commander 23 is received. If the remote control signal has not been received, the process returns to step 401, and if the remote control signal has been received, FIG.
Then, the process returns to step 401.

Next, in step 401, the DTMF sound is DT
Processing continued from FIGS. 19 to 20 when the MF receiver 217 detects it and the information is interactive program information will be described.

As shown in FIG. 19, in step 403, D
When it is determined that the TMF signal is the interactive program information, it is determined whether or not it is the response start information [AA] (step 411). Then, if it is the response start information, the process proceeds to step 412, the adapter device main body 22 is shifted from the standby state to the receivable state, and the memory (the memory 302 in FIG. 16 and the response history memory 307 are initialized. Return to step 401.

When it is determined in step 411 that the information is not the response start information, the process proceeds to step 413, and it is determined whether or not it is the response end information [AD]. Then, if the information indicates that the response has ended, the process proceeds to step 414, and the adapter device main body 22 shifts from the receivable state to the standby state. Then, the process returns to step 401.

When it is determined in step 413 that the information is not the response end information, the process proceeds to step 415, and it is determined whether the data is evaluation data. If it is evaluation data, the process proceeds to step 416 to evaluate the operation history of the response history memory 307 using the evaluation data. Then, the process returns to step 401.

If it is determined in step 415 that the data is not the evaluation data, the process proceeds to step 417 to determine whether or not the data is the selection data. If the selected data is the selected data, the process proceeds to step 418, and based on the selected data and the evaluation result, it is selected whether or not the user of the own device is selected as a respondable person for the next question. Next, in step 419, the selection result is judged.

If the result of determination in step 419 is that the selected one has been selected, the process proceeds to step 420, to that effect is displayed on the display element 22LDa or the like, and then the process returns to step 401. If the result of determination in step 419 is that there is a leakage from the selection, the process proceeds to step 421 and the adapter device main body 22
To the calling restriction state of the response. Further, after proceeding to step 422 and turning off the ID transmission flag of the user or the own device, proceeding to step 423, the user is alerted by the buzzer that the user has not been selected, or displayed on the display element 22LDa or the like. Then step 401
Return to.

If it is determined in step 417 that the data is not the selection data, the process proceeds to step 424 (selection + ID
(Request) Judge whether it is data or not. And (selection +
ID request) data, go to step 425,
Based on the selection data and the evaluation result, it is selected whether or not the user of the own device is selected as a respondent to the next question. Next, in step 426, the selection result is judged.

If the result of determination in step 426 is that there is a selection, step 427 is proceeded to, the ID transmission flag of the user or the own device is turned on, and then step 4
In step 28, the fact is displayed on the display element 22LDa or the like. Then, the process returns to step 401.

If the result of determination in step 426 is that there is any omission from the selection, step 429 follows and the adapter device main body 22 is shifted to the call origination restriction state for response. further,
In step 430, the I or
After the D transmission flag is turned off, the process proceeds to step 431, where the user gives an alarm with a buzzer or displays on the display element 22LDa or the like. Then, the process returns to step 401.

If it is determined in step 424 that the data is not (selection + ID request) data, the flow advances to step 432 to determine whether the data is question data. If it is question data, the process proceeds to step 433, and it is determined whether or not the response completion flag is turned on. If the response completion flag is not on, in step 434, the previous response history in the response history memory is set to “not responded”, and then the process proceeds to step 435. When the responded flag is on, the process directly proceeds from step 433 to step 435.

At step 435, the question data is saved. Next, proceeding to step 436, the response completion flag is set off, and further proceeding to step 4437, measurement of the response permission time is started. Then, the process returns to step 401.

When it is determined in step 432 that the question data is not the question data, the process proceeds to step 438 to determine whether the information is call restriction release information. If it is the calling restriction release information, the process proceeds to step 439 to release the calling restriction of the own device, and then returns to step 401. If it is not the calling restriction release information, the process directly returns to step 401.

Next, in step 401, the DTMF sound is set to D
Not detected by the TMF receiver 217, and step 40
FIG. 2 when it is determined that the remote control signal is received in step 5
The subsequent processing of FIG. 1 and FIG. 22 will be described.

First, as shown in FIG. 21, step 44
At 1, it is determined whether or not the received remote control signal is a response operation signal, that is, a signal of an option number. If it is not a response operation, the process proceeds to step 442 to perform processing other than the response operation, and then returns to step 401.

When it is determined in step 441 that the operation is a response operation, the process proceeds to step 443 to determine whether the question data has been received. If it has not been received, the process proceeds to step 444 to notify the user of an operation error by, for example, a buzzer. Then, the process returns to step 401.

When it is determined in step 443 that the question data has been received, the process proceeds to step 445,
Determine if the response to the question has already been completed. If the response to the question is completed, the process proceeds to step 446, and the user is informed of the operation error by, for example, a buzzer. That is, in this example, only the first response is valid. Then, the process returns to step 401.

If it is determined in step 445 that the response to the question has not been completed, the flow advances to step 447 to determine whether or not the response has been made within the allowable time range.
If the permission time has been exceeded, step 44
Proceeding to step 8, the user is informed of the operation error by, for example, a buzzer. Also, the ID transmission flag is turned off. Then, the process returns to step 401.

If it is determined in step 447 that the response has been made within the permitted time range, the flow advances to step 449 to determine whether or not the call restriction state is set. When the calling restriction is set, the process proceeds to step 450, and the user is informed of the operation error by, for example, a buzzer. Then, the process returns to step 401.

If it is determined in step 449 that the call is not restricted, the process proceeds to step 451 and the response history is stored in the memory. Then, step 45
Proceed to step 2 and automatically dial the answering telephone number corresponding to the response option number. Next, in step 453, it is determined whether the ID transmission flag is on.

If it is determined at step 453 that the ID transmission flag is on, then the routine proceeds to step 454,
After confirming the incoming call to the other party, the own device ID or the user ID, which is the specified additional information, is transmitted, and then the on-hook (line open) is performed. As the designated additional information, all response histories of a series of questions may be transmitted. In this case, the broadcasting station side can easily understand whether the responder has responded similarly to a series of a plurality of questions. When the process proceeds to step 454, the telephone line is cut through as described above, and the broadcasting station side and the receiving device side are directly connected via the telephone line. afterwards,
Go to step 456.

On the other hand, when it is determined in step 453 that the ID transmission flag is off, the flow proceeds to step 455, and after confirming that the incoming call for the response is received, the state is changed to the on-hook state. Then, it progresses to step 456.

Then, in step 456, the response completion flag is turned on to end the response, and then in step 4
Return to 01.

As described above, when a telephone voting service such as telegon is used to make a response to an interactive program, a response associated with a plurality of questions can be expected. Then, since the calling side is limited to the calling side, it is possible to prevent the calling of the unnecessary response, and the user is not burdened with the unnecessary calling charge.

In particular, in the case of the current telegon, voting is accepted only for about 5 minutes, and voting beyond that time will be invalid, but it is necessary to control a large number of subscriber exchanges with the database center. Therefore, there is a case where the subscriber exchange station accepts the incoming call even after the time for allowing the acceptance of the vote has passed. However, in the case of the above-described embodiment, the receiving device on the responder side limits the calling within the response permission time range included in the question data, so that the responder may make an invalid vote. Can be prevented.

In the case of the above example, question data,
Since the evaluation data and the selection data are added to the head identifier as the structure of the data packet, the type of the packet can be easily discriminated.

Further, the check data at the end of the packet allows the reception / response apparatus to judge and avoid mere erroneous reception or erroneous operation of the reception / response apparatus due to reception from the middle due to channel switching during data packet broadcasting. .

Also, in the above example, in the cut-through state, the response history information of the receiving device can also be sent to the broadcast station side, so the broadcast station side effectively used this response history information. It is also possible to broadcast interactive programs.

In the above example, the interactive program information is DTMF.
The signal is used to be multiplexed with the broadcast sound.
DTMF signal receivers are widely used for telephones, and adapter devices for receiving devices can be manufactured at low cost. Since the interactive program information is a DTMF sound, the microphone of the adapter device picks up the sound and the built-in DTMF receiver decodes the sound. Therefore, in the receiving system, the television receiver does not need to be improved at all.

However, the DTMF signal receiving / decoding section may be built in the television receiver, and the NCU section may be built in the television receiver instead of the above-described adapter configuration. In this case, the remote commander for responding and the remote commander for the television receiver can be shared.

The question data, the evaluation data, the selection data, and the (selection + ID request) data need not be sequentially broadcast, but may be broadcast at the same time. In such a case, the receiving device temporarily stores these data sent at the same time in the memory and appropriately reads them to perform evaluation and selection processing. In this case, the timing of evaluation and the timing of selection can be instructed from the broadcast side using multiplexed data.

[Other Embodiments] The program related information of the interactive program may be superimposed on an empty horizontal section within the vertical blanking period of the video signal. Also, in the case of multiplex broadcasting in which data is multiplexed as a sub-audio signal of audio multiplex or a signal in a band different from that of a video signal or an audio signal as a main broadcast signal for carrying multiplexed data is used, It is possible to deal with the problem only by changing the extraction and decoding processing part of.

The present invention can also be applied to satellite broadcasting and cable television broadcasting. Further, information such as the question data, the evaluation data, and the selection data as described above is configured by using, for example, a DTMF signal in a relatively narrow audio band as in the above example, and is multiplexed with the main broadcast audio signal and broadcast. If you do, AM, FM
It is also possible to apply to the receivers corresponding to the radio broadcasting and the PCM audio broadcasting.

In the FM radio broadcast wave, "FM
It is called "character multiplex broadcasting", and it has been realized that data such as character information is multiplexed and transmitted together with a program of the original audio broadcasting.
FM receivers that can display character information on a display element such as a CD (liquid crystal display element) have been put on the market, and the FM character multiplex broadcast enables information such as the question data, selection data, and evaluation data described above. Multiple broadcasts are also possible.

That is, this FM text multiplex broadcasting can be received by mobile such as an automobile, is called DARC system, and the standard for multiplexing digital data such as character information is as follows.
The sub-carrier frequency is 76 kHz, the transmission rate is 16 kbit / sec, the modulation method is LMSK, and the error correction method is (272,
190) A product code based on a shortened difference set cyclic code.

As for the program service such as character information, there are distinction between levels 1, 2, and 3. All of these are for presenting (displaying) character information and the like by dot display, but Level 1 includes 15.
This is a service for receivers that can display 5 characters x 2.5 lines, and the information is characters. Level 2 is a service for a receiver capable of displaying 15.5 characters x 8.5 lines including a header part, and information is characters and figures. Level 3 is a traffic information service for a receiver that can display a detailed map on a CD-ROM, that is, a navigation system.

As the level 1 program service, news, weather forecast, traffic information, entertainment and main complementary programs are considered. In this case, entertainment includes fortune telling, listener message boards,
It provides information such as quizzes and town information.

The main supplementary program includes supplementary information of the program such as the music title, performer name, telephone number / FAX number at the time of request when the original audio broadcast program is a music program. It is provided. In the following, main complementary programs are referred to as “program information” or “program-linked”.

Further, as a program service other than the above,
"Urgent information" provided at any time when there is an urgent need
Is also considered.

FIG. 23 shows the frame structure of the LMSK signal multiplexed in the FM character multiplex broadcasting. One frame of the LMSK signal is composed of 272 blocks, and each block has 288 bits.

Further, one frame is divided into 190 data packet blocks and 82 vertical parity packet blocks, and the vertical parity packet blocks are distributed and transmitted.

A 16-bit BIC (block identification code) is added to the beginning of each block. This B
Four types of ICs are used to distinguish each parity packet and identify the beginning of the frame.

The block of the data packet is BI
It has a 176-bit data packet following C, followed by a 14-bit CRC code, followed by an 82-bit lateral parity check code.

In this case, the CRC code is added to detect the residual error after the error correction by the product code. Further, the block of vertical parity packets is assumed to have a vertical parity packet of 272 bits following the BIC.

Further, as shown in the upper part of FIG. 24, each data packet is composed of a 32-bit prefix and a 144-bit data block following the prefix.

As shown in the lower part of FIG. 24, this prefix is composed of a service identification code, a decoding identification flag, an information end flag, an update flag, a program number, a page number, a data link code, and a data packet number. .

The service identification code is 4 bits and identifies the program content. For level 1, "1" is general information for sequential reception processing, and "2" is recording reception processing. General information, "4" is traffic information.

In this case, the sequential reception process is a mode in which the decoding process of the presentation is started as soon as the first data packet of the program data or page data arrives at the receiver, and the recording reception process is the program data or Receives and records all page data and CRs for each data group
In this mode, the presented decoding process is started only after the error correction process using the C code is performed.

[0188] Then, in the case of a program in which it is necessary to set the timing of presentation on the receiving side on the transmitting side, or a program which cannot be presented if the decoding process is started after the final packet of the data group is obtained, It is a reception process.

The decoding identification flag is 1 bit and is set to "1" when the error correction circuit of the receiver outputs the data by decoding only in the horizontal direction, and the data is decoded after the horizontal and vertical directions. When outputting, it is set to "0".

In the successive reception process, when the decoding identification flag is "0", the receiver receives the BIC at the head of each data packet, and receives the BIC at the head of the data packet 302 packets after. At this point, it is specified to perform a decoding process for presentation of each data packet.

The information end flag is 1 bit and is set to "1" when the data group to be transmitted with a certain data group number ends, and "0" otherwise.
It is said that Furthermore, the update flag is 2 bits and is incremented by 1 each time the data group is updated. The program number is 8 bits and the page number is 6 bits, and a data group number is formed by both.

Further, the program numbers are from 0 to 255, "total contents" are assigned to "0", and "254" is assigned to the main complementary programs (program information or program interlocking).
"255" is assigned to each emergency information.

The page numbers are from 1 to 62, that is, one program has a maximum of 62 pages.
One page corresponds to one or a plurality of data groups, and one data group is composed of one or a plurality of data blocks.

Further, since the data link code is 2 bits and the data that should belong to one data group is a large amount of data such that the number of packets exceeds the maximum value of the data packet number, the maximum is possible. It is a code for linking in the order of 0 → 1 → 2 → 3 between the data groups when divided into four data groups and transmitted by the same data group number with different data link codes.

The data packet number is 8 bits and is assigned in order from "0" to indicate the order of data packets in one program. That is, it indicates the number of the data packet in one program.

In Level 1, one page is generally in the display format of 15.5 characters × 2.5 lines, but it may be in the display format of 15.5 characters × 8.5 lines. . Further, the character data in this case is to specify a character to be displayed by a JIS code and alphanumeric characters, hiragana, katakana and the like.

The receiver corresponding to the level 1 is, for example, an LCD (liquid crystal display), as described above.
The one having a display screen capable of displaying 15.5 characters × 2.5 lines is used.

The receiver receives the LMSK signal together with the stereo composite signal, decodes the above character data from the LMSK signal, and writes the decoded character data in the buffer memory.

Further, the receiver or the remote control transmitter for remotely controlling the receiver is provided with a "total table of contents" key. By operating this key, the receiver displays the total table of contents (main menu) on the display screen. To be presented.

Further, the receiver or remote control transmitter is
In addition, a "Page (screen) advance" key is provided. By operating this key, the display screen will display the next page, or the next two lines of the page with the 8.5 line display format. To be done.

Then, when the user selects and determines the number of the item to be viewed from the total contents, the contents of the selected and determined item are further presented. For example, when the user selects "weather forecast" from the total table of contents, the table of contents such as "today's weather" and "tomorrow's weather" is presented.

Further, when the user selects and decides the number of the item to be seen from the table of contents, the first page of the decided item is presented. For example, when the user selects "today's weather" from the above table of contents, specific character information about "today's weather" is presented.

In the embodiment described below, F
Using the level 1 program service of M character multiplex broadcasting,
The question data, the evaluation data, the selection data, and the (selection + ID request) data described above are multiplexed and broadcast in synchronization with the FM radio broadcast.

FIG. 25 shows the configuration of the receiving device side in this embodiment, and is an example of a signal system when applied to an on-vehicle FM receiver. This FM receiver is
It has level 1 reception capability for teletext.

That is, the FM signal received by the antenna 501 is the tuner circuit 502 of the synthesizer system.
Is supplied to the FM demodulation circuit 504 through the intermediate frequency amplifier 503 while the FM signal is converted into an intermediate frequency signal.

Thus, from the demodulation circuit 504, the addition signal (L + R) of the stereo left and right audio signals L and R, the DSB signal balanced-modulated by the difference signal (LR), and the pilot signal are output. Then, the frequency-multiplexed signal with the LMSK signal in the FM character multiplex broadcasting described above is extracted.

Then, this frequency-multiplexed signal is supplied to the stereo demodulation circuit 505, the audio signals L and R are demodulated from the addition signal (L + R) and the DSB signal, and these signals L and R are passed through amplifiers 506L and 506R to the left and It is supplied to the right channel speakers 507L and 507R.

Further, in this FM receiver, the microcomputer 510 is used for selecting a channel in the tuner circuit 502 and displaying characters by FM character multiplex broadcasting.
Is provided.

That is, this microcomputer 51
0 is a CPU 511 for executing a program, and R

RAM 514 for receiving buffer of character multiplex broadcasting data
Have and. In this case, the ROM 512 is stored in the above-mentioned FIG.
In addition to the processing routines shown in FIGS. 7 to 22, various routines and data for displaying a predetermined character string (text) are written. In the case of this embodiment, step 401 and step 4 in FIG.
The portion 02 is changed to a character multiplex data detection processing step and a character multiplex data decoding processing step, but the others are almost the same.

The memories 512 to 514 are connected to the CPU 511 through the system bus 518, and the bus 518 has an interface circuit (port).
515 to 517 are connected.

Further, the interface circuit 515 supplies data for tuning to the tuner circuit 502, and the tuning is executed. Further, the demodulated signal from the demodulation circuit 504 is supplied to the decoder circuit 531 and the data in the FM character multiplex broadcast is decoded and taken out from the LMSK signal. This data is written in the RAM 514 through the interface circuit 516, and the data in the RAM 514 is , Always updated with the latest data.

Further, the interface circuit 517 includes
Various operation keys 532 configured by a non-lock type push switch are connected, and the key output is captured by the microcomputer 510. In this way, when any one of the keys 532 is pressed, the pressed key is determined by the CPU 511, and the process corresponding to the pressed key is executed.

However, when the FM receiver is mounted on a vehicle,
Since the operation panel is narrow and a large number of operation keys cannot be arranged, in this example, the keys 532 are only the keys with high operation frequency and the keys with high importance,
Other operations are performed by a remote controller (remote operation).

Therefore, the receiving circuit 533 of the remote controller is also connected to the interface circuit 517. In this example, the remote controller is of infrared type, and the receiving circuit 533 includes a light receiving element that receives infrared rays from the transmitter 550 of the remote controller and a decoder circuit that decodes the remote control signal from this light receiving element. Have and.

Further, the remote controller transmitter 550 is also provided with various operation keys 551 (551A to 551N) composed of non-lock type push switches.
Although a part of the key 551 has the same function as the key 532, when any key of the keys 551 is pressed, data corresponding to the pressed key is formed, and the data is converted into infrared rays to be transmitted to the FM receiver. Sent to.

Then, in the FM receiver, the transmitter 5
When the infrared ray transmitted from 50 is received by the receiving circuit 533, the original data is taken out and this data is supplied to the interface circuit 517. Thus, similarly to the case where the key 532 is pressed, when the key 551 is pressed, the processing corresponding to the pressed key is executed by the microcomputer 510.

Further, a bus 518 is connected to a font ROM (character generator) 521 having font data for converting character codes sent by FM character multiplex broadcasting into display data, and a display memory. 522 and the display controller 52
3 is connected to the controller 523, and an LCD 540 is connected to the controller 523 as a display element.

In this case, the LCD 540 is assumed to have a display capacity of 15.5 characters × 2.5 lines in this example. The memory 522 is the LCD 540.
Corresponding to the dot display method of
It has the capacity for one screen. In the following, a teletext program is performed at level 1, and one page has the size (capacity) of one screen.

Then, the character code held in the RAM 514 is read by the CPU 511, the read character code is converted into display data using the font data of the ROM 521, and this display data is stored in the memory 522. Written in. Further, at this time, the controller 523 repeatedly reads the display data of the memory 522, converts the display data into a display signal, and displays the display signal on the LCD.
540 is supplied. Therefore, the LCD 540
The characters of the character code read by the CPU 511 from the RAM 514 are displayed.

The system bus 518 is further provided with a configuration similar to that of the adapter device main body 22 described above, and a telephone circuit unit 56 having a built-in NCU and having an automatic calling function.
0 is connected. This telephone circuit unit 560 is a telephone line 5
In addition to being connected to 61, an external telephone (not shown) can be connected. In the telephone circuit unit 560, the microcomputer 510 plays the role of the function of the microcomputer 300 in the circuit shown in FIG.

[0221] In the above-mentioned configuration, when broadcasting, for example, a win-win type interactive program as described above as an FM radio broadcast program, the FM character multiplex data is displayed in accordance with the question and option broadcast by the announcer. Question data as shown in 7 is broadcasted multiple times, and then
Or at the same time, evaluation data, selection data, (selection + I
D request) Data is multiplexed. These data are
It is stored in the RAM 514 of the FM radio receiver shown in FIG.

Then, when the viewer having the FM radio receiver shown in FIG. 25 inputs the number of the option as the answer to the question, for example, with the remote control transmitter 550, the question stored in the memory 514 as described above. Using the data, an automatic call is made through the telephone circuit unit 560 to the telephone number of the telegon corresponding to the inputted option number. Then, the history of the response is sequentially stored in the RAM 514.

Then, each response or the history of responses is evaluated by the evaluation data acquired as the multiplex data, and the winner or the loser is selected by the selection data.

[0224] The provision of questions by the broadcast program and the multiplex broadcasting of question data, evaluation data, etc. are repeated.
Finally, according to the (selection + ID request) data, the selection is performed, and if a winner, the user I is sent to a predetermined response destination.
Response information including D is sent. Further, if the player is a loser, subsequent responses are limited.

In this way, the telephone voting service such as the telegon service is used for the response, and the question data, the evaluation data, and
By broadcasting the selection data or the like, it is possible to provide an interactive program in which a response in which a plurality of questions are associated can be expected.

In the case of the system using the FM text multiplex broadcasting, if the evaluation data and the selection data are displayed on the LCD 540, the user can confirm the evaluation result and the selection result with respect to his response. You can easily.
Moreover, the display of the evaluation data and the selection data can be selected by the user from the menu display, so that the user can select whether to enjoy the interactive program without seeing the answer or to enjoy while watching the answer. can do.

[0227]

As described above, according to the present invention, the broadcasting station side broadcasts the question data, the evaluation data, and the selection data, and the receiving device on the response side evaluates the responses up to that time, It is judged whether or not the broadcasting station has selected it so that it can make a subsequent response, and if there is a failure in the selection, the response side limits calling, so the telephone voting service is used to make a response. Even when it is performed, it is possible to broadcast a program that expects a response in which a plurality of questions are associated.

Further, it is possible to easily narrow down the responders, and it is possible to easily judge whether or not the responders can avoid the congestion state within the range of the number of telephone lines prepared in advance by narrowing down. Can be determined. Therefore, after the number of responders has reached such a number, it is easy for the broadcasting station side to obtain the identification information for identifying the responders via the telephone line.

Since the call origination of the response limits the call origination of the response, it is possible to prevent unnecessary call origination to the telephone line network.
