Abstract

<P>PROBLEM TO BE SOLVED: To minimize and correct missing of the viewing and listening data (broadcast ID signal embedded by watermark, or the like) without providing any special facility on the outside of a broadcast station or a tabulation center. <P>SOLUTION: When the station code and the service code of the viewing and listening data are "unknown" in a certain time, a computer 302 determines whether there is an error occurrence record on the operation status data at that time (S303). If there is an error occurrence record, the computer 302 determines the error level (S304) and executes predetermined processing, e.g. interpolation of the viewing and listening data, setting to "fault (impropriety)" or setting to "fault (off-the-air)", according to the error level, the station code and/or the service code in the time before and after the certain time (S313, S315, S321, S325). <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a viewing data processing system, a viewing data processing apparatus and method, and a program.

Conventionally, a system using a broadcast identification (ID) signal has been proposed as one of methods for measuring a television audience rating and a radio audience rating (see, for example, Patent Document 1 and Patent Document 2). The broadcast ID signal is a signal uniquely assigned to each broadcast station for identifying the broadcast station, and can include time data and the like.
In this system, a broadcast ID superimposing device for superimposing a broadcast ID signal on a broadcast signal is provided on the broadcast station side, and a broadcast identification (ID) signal is configured within an audio signal frequency band, which is used as an audio signal of a broadcast program. Superimpose. On the other hand, on the receiving side, the survey target person is always allowed to carry a broadcast ID decoding device having a microphone. The subject of the survey carries this broadcast ID decoding device during the entire day or during the waking time. Then, if the broadcast ID number is decoded from all the ambient sounds contacted by the survey subject, the fact is recorded in the memory inside the apparatus. Such a broadcast ID decoding record is provided with a broadcast ID code and its decoding time, and the recording company collects the record with a separate collecting device, and the TV audience rating and radio listening rate are calculated.
In addition, a system is disclosed in which a broadcast wave is constantly monitored, and the monitoring result is reflected in the audience rating and listening rate tabulation (for example, see Patent Document 3).
FIG. 16 shows a configuration diagram of a conventional media contact rate investigation system.
The conventional media contact rate survey system includes, for example, a monitor facility 1, a calculation facility 2, and a survey target person's home device 3. The calculation facility 2 includes, for example, a computer 21, interfaces (I / F) 22 and 23, and a storage unit 24.
The monitor facility 1 extracts a broadcast identification signal from the broadcast reception signal, creates and outputs quality data indicating the quality of the broadcast identification signal. The calculation facility 2 inputs the quality data from the monitor facility 1 through the interface 23 and the log data related to the audience rating / listening rate from the survey target person's home device 3 through the interface 23. The computer 21 of the calculation facility 2 obtains the audience rating / listening rate for each hour based on the received log data, identifies the time when the broadcast and the broadcast identification signal are not normally received based on the quality data, and at that time The audience rating / listening rate of the corresponding created storage unit 24 is corrected, stored in an aggregate data file regarding the audience rating / listening rate, and output.

1. System Configuration FIG. 1 shows a system configuration diagram of the present embodiment.
This system includes survey household devices 101-1 to 101-m, broadcasting station facilities 102-1 to 102-n, and collection / aggregation facilities 103.
The broadcast station facilities 102-1 to 102-n transmit broadcast signals, generate operation status data, and send them to the collection / aggregation facility 103. The operational status data includes, for example, data relating to the operational status such as the operational status of the equipment existing on the broadcasting system in the broadcasting station facility and the working / preliminary information indicating which of the redundant systems is in use. Can do.
The survey household devices 101-1 to 101-m generate viewing data and send it to the collection / aggregation facility 103. The viewing data can include, for example, data related to viewing such as viewing date, time, station code, and / or service code. For example, in the case of terrestrial digital broadcasting, the service code indicates codes of various broadcasting services such as HD broadcasting, SD broadcasting 1 to 3, and 1 segment broadcasting.
The collection / aggregation facility 103 collects viewing data sent from each of the survey household devices 101-1 to 101-m and generates audience rating data using the viewing data. The collection / aggregation facility 103 generates correction determination data based on the operational status data sent from the broadcasting station facilities 102-1 to 102-n.

The collection / aggregation facility 103 corrects each audience rating data based on the correction determination data, and improves the accuracy of the audience rating data.

FIG. 2 shows an example of a configuration diagram of a broadcasting station system of the terrestrial digital broadcasting facility in the broadcasting station facility.

This diagram is merely an example, and the present invention is not limited to the devices represented on this system. In the illustrated example, the case of a system having a dual system is taken as an example, but the present invention can also be applied to a system having a triple system.
The broadcast station facilities 102-1 to 102-n are a broadcast material system device 201, a 1 system broadcast transmission system 200-1 and a 2 system broadcast transmission system 200-2, an active standby switching device 206, a transmission facility 207, and an alarm collection device 209. The operation status data generation device 210 and the operation status data file 211 are provided. The 1-system broadcast transmission system 200-1 and the 2-system broadcast transmission system 200-2 are, for example, material switching machines 202-1 and 202-2, embedding devices 203-1 and 203-2, a compression device 204-1, respectively. 204-2, multiplexers 205-1 and 205-2, and the like. The 1-system broadcast transmission system 200-1 and the 2 -system broadcast transmission system 200-2 are not limited to this, and can have an appropriate configuration including the embedding devices 203-1 and 203-2.
Broadcast materials output from the broadcast material system device 201 such as a material playback machine and studio live video are respectively transmitted to the material switching machine 202-1 in the first system broadcast transmission system 200-1 and the second system broadcast transmission system 200-2. 202-2. The material switching machines 202-1 and 202-2 perform selection switching of the broadcast material based on the broadcast schedule, and output it to the embedding devices 203-1 and 203-2. The embedding devices 203-1 and 203-2 embed information (broadcast identification (ID) signal etc.) necessary for audience rating measurement such as broadcasting station codes and / or service codes in the broadcast material, and compressing devices 204-1 and 204. Output to -2. The compression devices 204-1 and 204-2 convert the embedded broadcast material (signal) into a data stream by compression or the like, and output the data stream to the multiplexing devices 205-1 and 205-2. For this embedding, for example, an appropriate embedding technique such as an image watermark technique or an audio watermark technique can be used. Multiplexers 205-1 and 205-2 multiplex data streams such as broadcast materials and data broadcasts, and output the multiplexed data streams to active backup switching device 206. The active standby switching device 206 selects one of the broadcast transmission systems having redundancy prepared in two or more systems (in this example, one of the first system and second system broadcast transmission systems 200-1 and 200-2). And output to the transmission facility 207. The transmission facility 207 modulates the signal and then transmits the radio wave via the antenna.

As shown here, there are a plurality of devices on the broadcast transmission system. For example, when a failure occurs in these active systems, it is necessary to pick up the information and quickly switch the system to the redundant system to suppress the influence on the broadcast signal. Each device / apparatus outputs alarm information when a failure occurs. The alarm information is information for identifying a device in which a failure has occurred. The alarm information output from the embedding device 203 includes, for example, failure information of both a failure of a local decoder that is a decoder for embedding a watermark and an abnormality of an output signal (broadcast signal).

The alarm collection device 209 collects alarm information output from each device existing on the broadcast transmission systems 200-1 and 200-2, and outputs the collected alarm information to the operation status data generation device 210. Further, the alarm collection device 209 suppresses the influence on the broadcast signal by an appropriate method such as prompting a system / switching operation for working / standby or automatically outputting a system switching instruction according to the collected alarm information. The current / spare information indicating the current / standby status of the system, such as whether the broadcast transmission system of the system is the active system, is output to the operation status data generating apparatus 210.
The operation status data generation device 210 generates operation status data using the alarm information and the current / preliminary information output from the alarm collection device 209. The operation status data generation device 210 stores the operation status data as necessary, and transmits the operation status data to the collection / aggregation facility 103 by an appropriate means. As a transmission method, an appropriate wired or wireless network may be used, or transmission equipment 207 and an antenna may be used. Further, the operation status data generation device 210 may be configured to directly use alarm information output from each single device without using the alarm collection device 209.
In general, the transmission equipment 207 is also provided with redundancy, but since it is omitted in FIG. 2, it may be provided with redundancy. In digital terrestrial broadcasting, it is also assumed that a plurality of broadcasting services such as SD split broadcasting are performed at the same time, and devices from the material switching machines 202-1 and 202-2 to the compression devices 204-1 and 204-2 are assumed. May be prepared independently for each broadcasting service and combined into one stream by the multiplexing devices 205-1 and 205-2.

FIG. 3 shows a configuration diagram of the embedding device.
This figure shows a configuration example of the embedding device 203 having a function of monitoring its own operation status and a function of notifying the alarm collection device 209 of the information.
The embedding device 203 includes, for example, interface (IF) units 401, 403, 404, and 410, an information embedding unit 402, an embedding information monitoring unit 405, an output signal monitoring unit 406, an input signal monitoring unit 407, and a power supply monitoring. Unit 408 and an operation state determination unit 409.
The IF unit 401 is an interface for inputting a broadcast signal. For example, an SDI (Serial Digital Interface) signal or an MPEG2_TS (MPEG2_Transport Stream) signal may be input. The information embedding unit 402 receives time information input via the IF unit 404 and information that can specify a broadcasting station, a broadcasting service, a program, and the like, and embeds data in a broadcast signal such as video and / or audio. I do. Information that can specify the broadcasting station / broadcasting service is determined in advance for each system in which the embedding device 203 is installed. Therefore, if a mechanism that can be held in the embedding device 203 is provided in advance, the information cannot be necessarily transmitted via the IF unit 404 of the embedding device 203. There is no need to receive each time. The embedded signal is output from the IF unit 403 and passed to a subsequent device. The embedded information monitoring unit 405 has a mechanism for detecting by the same method as the detection device installed in the survey household as a mechanism for confirming that data is normally embedded. Since the embedded information is already known, the embedded information monitoring unit 405 determines that the detected data does not completely match, and determines an abnormality, and notifies the operation status determination unit 409 of the error. The output signal monitoring unit 406 takes a difference signal between video data and / or audio data before and after data embedding, and if the amplitude is greater than or equal to the amplitude of the data to be embedded, it determines that it is abnormal and notifies the operation status determination unit 409 of the error. To do. Note that the output signal monitoring unit 406 needs to delay the input signal in accordance with the delay amount associated with the embedding process when taking the difference. The input signal monitoring unit 407 monitors whether there is an abnormality in the signal input to the embedding device 203. Specifically, in the case of an SDI signal, the input signal monitoring unit 407 uses, for example, an EDH (Error Detection and Handling) signal or a CRC (Cyclic Redundancy Check) signal added to the signal to the embedding device 203. It is checked whether a bit error has occurred on the transmission system up to the input of, and if there is an error, it is determined to be abnormal and an error is notified to the operation status determination unit 409. The power supply monitoring unit 408 monitors the AC power supply voltage supplied to the embedding device 203 and the DC power supply voltage supplied to the element, and determines that it is abnormal if either or both of these power supply voltages are below a predetermined threshold. Then, an error is notified to the operation status determination unit 409. The operation status determination unit 409 receives an error notification notified from each monitoring unit of the embedded information monitoring unit 405, the output signal monitoring unit 406, the input signal monitoring unit 407, and the power supply monitoring unit 408. Together with the identification information indicating whether or not there is an abnormality in the embedding device 203 as alarm information for the active standby switching control, the external (via the alarm collection device 209 and / or operation) via the IF unit 410 Notify the situation data generator 210). Note that the operation status determination unit 409 can be configured so that, for example, when a certain failure has already occurred, the alarm information is not notified to the outside again even if another failure occurs.

In the present embodiment, for example, the error level is classified into 0 to 4 as follows. Further, the error level data can be used to indicate that the working / standby system after the error has been switched (data “C”).
Error level 0: embedded information can be detected, and the broadcast content is normal (when a failure occurs in the standby embedded device).
Error level 1: embedded information can be detected, but the broadcast content itself is unnatural.
Error level 2: Embedded information cannot be detected, but the broadcast content itself is normal.
Error level 3: Embedded information cannot be detected, and the broadcast content itself is unnatural.
Error level 4: Embedded information cannot be detected and a wave has stopped.

The viewing data file before correction includes, for example, a date, time, station code, and service code. The corrected viewing data file includes, for example, date, time, corrected station code, corrected service code, and correction processing type.

3. Operation Status Data Generation Processing FIG. 10 is a flowchart of operation status data generation processing (understanding of the failure occurrence status).
The operation status data generation device 210 classifies into, for example, five levels (0 to 4) according to the error level based on the alarm generation status of each single device or the alarm collection device 209 and information on current / spare, etc. The operation status data including the code, service code, error level, generation / recovery data, generation / reset system data, and working system data is recorded in the operation status data file 211. At this time, the operation status data generation device 210 determines whether or not the information embedded for the purpose of measuring the audience rating is normally embedded. If the information is not normally embedded, the broadcast status at that time is normally viewed. The error level is determined by determining whether or not the broadcast content is ready, whether or not the broadcast content is not unnatural.
The operation status data generation device 210 is connected to the alarm collection device 209 or a single device and monitors alarm information (S101). Here, the alarm information is, for example, information indicating which device (device) has failed. The alarm information from the embedding devices 203-1 and 203-2 includes the presence / absence of an abnormality in an embedding processing unit such as decoding in the devices and the presence / absence of an abnormality in a broadcast output signal. The operational status data generation device 210 monitors the current / preliminary information of the system (eg, which of the first system or the second system is the current system) from the alarm collection device 209 (S103). The operation status data generation apparatus 210 determines whether an alarm has occurred based on the input alarm information (S105). If no alarm has occurred, the operation status data generation apparatus 210 returns to step S101 and continues the subsequent processing. On the other hand, when it is determined that an alarm has occurred based on the alarm information and the working / standby information, the operation status data generating apparatus 210 determines whether a failure has occurred in the working system (S107).
If it is determined in step S107 that a failure has not occurred in the active system, the operation status data generation apparatus 210 uses the standby embedding apparatus 203 whose alarm occurrence location on the equipment system is based on the alarm information and the active / preliminary information. It is determined whether or not there is (S125). In the case of No here, the operation status data generation apparatus 210 returns to step S101 and continues the subsequent processing. On the other hand, in the case of Yes, the operation status data generating apparatus 210 determines that the embedded level can be detected and the broadcast content is normal (when a failure has occurred in the standby embedded apparatus), and the error level is 0 (S127). ).

On the other hand, if a failure has occurred in the active system in step S107, the error level is determined as follows.
Based on the alarm information and the working / preliminary information, the operation status data generating device 210 has an alarm occurrence location on the device system preceding the embedding device 203 for a working watermark or the like (direction from the broadcasting material system device 201 toward the transmission facility 207). It is determined whether or not (S109). In the case of Yes, the operation status data generation device 210 determines that the embedded information can be detected, but the broadcast content itself is unnatural and has an error level 1 (S111).
When it is determined in step S109 that the alarm occurrence location on the device system is not before the active embedding device 203, the operation status data generation device 210 generates an alarm on the device system based on the alarm information and the current / preliminary information. It is determined whether or not the location is the active embedding device 203 (S113). In the case of Yes, the operation status data generation apparatus 210 determines whether or not the embedding processing unit such as local decoding for embedding watermark information is abnormal and the content of the broadcast output signal is normal (S115). For example, a failure of the embedding processing unit such as local decoding of the embedding device 203 is output by the embedding device 203 (for example, an operation state determination unit based on detection data such as the embedding information monitoring unit 405 and / or the output signal monitoring unit 406). This can be determined from the alarm information from the embedding device 203 generated by monitoring the output 409). As for the failure of the broadcast output signal, alarm information from the embedding device 203 (for example, the output of the operation status determination unit 409 based on the detection data of the output signal monitoring unit 406 and / or the input signal monitoring unit 407), or The judgment can be made based on alarm information from each device generated by monitoring a broadcast signal by the compression device 204, the multiplexing device 205, the active backup switching device 206, the transmission facility 207, and the like. In the case of Yes, the operation status data generation apparatus 210 determines that the embedded information cannot be detected, but the broadcast content itself is normal, and the error level is 2 (S117). On the other hand, in the case of No in step S115, the operation status data generation apparatus 210 determines that the embedded information cannot be detected and the broadcast content itself is unnatural and the error level is 3 (S121).
If it is determined in step S113 that the alarm occurrence location on the device system is not the active embedding device 203, the alarm occurrence location is subsequent to the embedding device 203 (in the direction from the broadcast material system device 201 toward the transmission facility 207). Next, the operation status data generation device 210 determines whether or not the transmission facility 207 is stopped based on the alarm information (S119). In the case of No here, the operation status data generation apparatus 210 determines that the embedded information cannot be detected and the broadcast content itself is unnatural, and that the error level is 3 (S121). On the other hand, in the case of Yes, the operation status data generation device 210 determines that the embedded information cannot be detected and a wave has stopped, and the error level is 4 (S123).

When the error level is determined in steps S111, S117, S121, S123, and S127, the operation status data generation device 210 determines the date, time, station code, service code, and error according to the alarm information, working / preliminary information, and error level. Operation status data including the level, generation / recovery data, generation / recovery system data, and working system data is created, recorded in the operation status data file 211 (S129), and the process returns to step S101 to continue the subsequent processing.
The operation status data generation device 210 reads the operation status data from the operation status data file 211 at a predetermined timing or time, or in response to a request from the collection / aggregation facility 103, and sends an appropriate network to the collection / aggregation facility 103. To send through.

FIG. 11 is a flowchart of the operation status data generation process (understanding the failure recovery status).
It is necessary to identify the failure continuation period by grasping the recovery status of the generated alarm and the system switching status. This flowchart is executed in parallel with the flowchart of FIG. Note that steps S201 to S205 may be common to steps S101 to S105. The flow of operation status data generation processing for grasping the status at the time of failure recovery is shown below.
The operation status data generation device 210 is connected to the alarm collection device 209 or a single device and monitors alarm information (S201). The operation status data generation device 210 monitors the current / preliminary information of the system from the alarm collection device 209 (S203). The operation status data generation apparatus 210 determines whether an alarm has occurred for any device based on the alarm information (S205). If no alarm has occurred, the operation status data generation device 210 returns to step S201 and continues the subsequent processing. On the other hand, when an alarm occurs, the operation status data generation device 210 determines whether the 1-system / 2-system switching has occurred based on the current / preliminary information from the alarm collection device 209 (S207). When the operation status data generation device 210 determines that the 1-system / 2-system switching has occurred, the system name, the switching occurrence date / time, the error occurrence level (“C”), and the occurrence recovery data that have been switched and become active. (Return), occurrence return system data (return system: 1 system), working system data (2 system), and station code and service code based on the previous error information are recorded as operation status data in the operation status data file 211 ( S209). Here, the data shown in parentheses relate to the second line of the example of the operation status data files 211 and 304 in FIG.
On the other hand, if it is determined in step S207 that the 1-system / 2-system switching has not occurred based on the working / standby information from the alarm collection device 209, the operation status data generation device 210 proceeds to step S211.
The operation status data generation apparatus 210 determines whether or not the alarm has been restored (S211). When the alarm is restored, the operation status data generation device 210, based on the data about the error that occurred earlier, the recovery date and time, the station code and service code and error level of the recovered alarm, the occurrence return data (recovery), the occurrence return The system data (return system: 1 system) and the working system data (2 system) are recorded as operation status data in the operation status data file 211 (S213). Here, the data shown in parentheses relate to, for example, the third line of the operation status data files 211 and 304 in FIG. Thereafter, the process returns to step S201 and the subsequent processing is continued. On the other hand, in step S211, when the same alarm information as the error occurrence is continuously received based on the alarm information, the operation status data generation device 210 determines that the alarm has not been recovered, and returns to step S201 and thereafter. Continue processing.

In the first line of the example of FIG. 6, an error level 2 failure has occurred in the service code “001” of the station code “1111” on December 10, 2008 at 20:00: 00, and the system in which the failure has occurred Indicates that the current system is the first system. In the second line, system switching was performed on December 10, 2008 at 20:00:07, the working system was switched to system 2 (error level “C”), and the fault was recovered (occurrence recovery data “recovery” ")It is shown that. Further, the third line indicates that the cause of the failure of the error level 2 that occurred first has been resolved and the operation of the device has been recovered. At this time, the content of the broadcast failure is a failure of error level 2 (embedded information cannot be detected, but the broadcast content itself is normal) between December 10th, 2008 from 20:00:00 to 20:00:07 on the same day. It can be seen that occurred.
Next, in the fifth line, a failure of error level 3 occurs in the service code “002” of the station code “1111” at 21:30:17 on Dec. 10, 2008, and after the failure recovery work of the single device, The sixth line indicates that the operation of the device has been restored at 21:31:11 on December 10, 2000. In this example, since a quick recovery operation by switching the system after the failure occurred was not performed, error level 3 (embedded information was not detected and the broadcast content itself was unsightly between 21:30:17 and 21:31:11. This shows the case where a relatively serious failure, such as “) has continued for about one minute.
Next, in lines 8 to 10, an error level 1 occurs at 23:10:00 with a service code “001” of the station code “1111”, the system is switched at 23:10:08, and the active system is 1 system. And the failure was recovered, and then the cause was specified at 23:40:14, indicating that the operation of the device was recovered. At this time, as the content of the broadcast failure, a failure of error level 1 (embedded information can be detected, but the broadcast content itself is unsightly) occurs between 23: 10: 0 to 23:10:08. It shows that.
The operation status data is generated for each broadcast station by the operation status data generation device 210 in each broadcast station facility 102 and sent to the collection / aggregation facility 103.

4). Viewing Data Correction Processing FIG. 12 is an explanatory diagram for generating correction determination data from operation status data.
Processing for generating correction determination data for correcting viewing data from operation status data in the collection / aggregation facility 103 will be described below.
In general, in a method in which viewing data is generated by embedding information in a broadcast signal for each broadcasting station facility 102 and detecting the information, the data embedding unit is equal to the detection unit. For example, when embedding is performed in units of one minute, the detection side can acquire all information when all the data for one minute is input, and detection of information is performed one minute after the head of the data is recognized. it can. In short, when information is detected, it can be said that the station has been viewed for the past one minute. When information is embedded in every minute unit (for example, in units of 00 seconds to 59 seconds per minute), detected information is also detected in every minute unit. This unit is not limited to 1 minute and can be an appropriate unit. In the example shown in the figure, for example, correction determination data for a time of 20:01 is generated based on operation status data from 20:00:00 to 20:00:59. Similarly, it is shown that the correction determination data for the time of 20:02 is generated from the operation status data from 20:01:00 to 20:01:59.

FIG. 13 is a flowchart for creating a correction determination data file.
The collection / aggregation facility 103 receives the operation status data from each of the broadcasting station facilities 102-1 to 102-n and stores it in the operation status data file 304 (S401). The collection / aggregation facility 103 reads the operation status data file 304 and creates correction determination data including the date, time, station code, service code, and error level for each unit time (eg, every minute). The data is stored in the data file 306 (S403). Here, when there is no operational status data, the error level is blank or a predetermined value.
For example, the failure in the first to third lines in FIG. 6 occurred at 20:00:00 and recovered at 20:00:07, thus affecting the aggregation of viewing data at 20:01. The possibility is shown, and it is expressed in the viewing data aggregation unit in the first to third lines in FIG. Similarly, the 5th to 6th lines in FIG. 6 occur at 21:30:17 and have been restored to 21:31:11, which may affect the totaling of viewing data at 21:31 and 21:32. The correction determination data is as shown in the fifth to eighth lines of FIG. The correction determination data includes a view continuity (change in viewing station / service before and after) including the viewing data before and after failure recovery.

FIG. 14 is an explanatory diagram of an example in which the correction contents are classified based on the error level and the continuity of the viewing data before and after the failure recovery.
For example, in the case of error levels 0 to 1, correction is made because the location where the failure occurred occurs in the system before the information embedding device 203 regardless of the continuity of viewing, and thus does not affect viewing determination. Do not do. Even if “Unknown” (for example, station code unknown or zapping) exists in the viewing data, since there is no abnormality in the embedding operation, usually zapping (for example, frequent channel switching) It is reasonable to judge that the (state) has been performed.
Next, when the error level is 2 and there is continuity of viewing, the embedded information has not been detected, but it can be determined that there is a high possibility of continuing viewing during that time, so a failure has occurred. It is appropriate to interpolate the viewing data for the period with the data before the occurrence of the failure. If there is no continuity of viewing, it is clear that the channel has been changed during the period when embedded information cannot be detected, but the time cannot be specified. It is determined that it has been performed and is set to “Unknown”.
Next, when the error level is 3 and there is continuity of viewing, it is determined that the corresponding channel has been viewed because the embedded information cannot be detected and the broadcast is unfamiliar. Judgment ". If the error level is 3 and there is no continuity of viewing data, it is clear that the channel has been changed, but the period cannot be specified, so the data during the failure is zapped. Is determined to be “Unknown”.
Next, in the case of error level 4, for the same reason as in error level 3, if there is continuity of the viewing data, it is determined as “accident / stop”. If there is no continuity at error level 4, it is determined that zapping has been performed and “Unknown” is set.

FIG. 15 shows a flowchart of the correction process.
The illustrated example is a flowchart of processing for generating viewing data after correction based on the classification of the content of correction illustrated in FIG.
The computer 302 receives the viewing data from each of the survey household devices 101-1 to 101-m in advance, and stores the received viewing data in the viewing data file 305. In this example, viewing data is stored every predetermined time (eg, every minute). The computer 302 reads the viewing data from the viewing data file 305 (S301).
The computer 302 determines whether or not the station code and / or service code of the viewing data at time t is “Unknown” (S302). When it is determined that the station code and / or the service code of the viewing data at time t is not “Unknown”, the computer 302 does not correct the viewing data, and uses the corrected station code and service code as the viewing data. It is stored in the file 305 (S307: correction processing type A). If the station code and / or service code of the viewing data at time t is “Unknown”, the computer 302 determines whether or not there is an error occurrence history on the operation status data at that time (S303). ). If there is no error occurrence history on the operation status data at that time, the computer 302 stores the corrected station code and service code in the viewing data file 305 without correcting the viewing data (S307). On the other hand, when there is an error occurrence history in the operation status data at that time, the computer 302 obtains an error level (S304).
Regarding steps S303 and S304, the computer 302 uses the correction determination data file 306 created earlier to determine whether or not there is an error occurrence history based on the error level item for that time (S303), and obtain the error level. (S304). Alternatively, the computer 302 refers to the operation status data file 304, and if it is a unit time indicated by the time (for example, one minute indicated by 20:01, the time of 20:00:00 to 20:00:59 Data), the presence / absence of error occurrence history is determined based on the presence / absence of error occurrence / recovery data (S303), and the error level can be obtained (S304).
Next, the computer 302 determines whether the error level is “0” or “1” (S305). When the error level is “0” or “1”, the computer 302 stores the corrected station code and / or service code in the viewing data file 305 without correcting the viewing data (S307).
When it is determined in step S305 that the error level is not “0” or “1”, the computer 302 determines whether or not the error level is “2” (S309). When the error level is “2”, the computer 302 determines whether or not the station code and / or service code of the time immediately before the time matches the station code and / or service code of the time immediately after. When the determination is made (S311) and the two match, the computer 302 interpolates the viewing data with the station code and / or service code of the previous time (correction processing type B), and the corrected station code and / or Alternatively, the service code and the correction process type are stored in the viewing data file 305 (S313). On the other hand, if the two do not match, the computer 302 sets the corrected station code and / or service code to “Unknown” and describes the correction processing type “C” in the viewing data file 305 (S315).
If it is determined in step S309 that the error level is not “2”, the computer 302 determines whether or not the error level is “3” (S317). When the error level is “3”, the computer 302 determines whether or not the station code and / or service code of the time immediately before that time matches the station code and / or service code of the time immediately after. When the determination is made (S319) and the two match, the computer 302 sets the corrected station code and / or service code as “accident (unfriendly)” and describes the correction processing type “D” in the viewing data file 305. (S321). On the other hand, if the two do not match, the computer 302 sets the corrected station code and / or service code to “Unknown” and describes the correction processing type “C” in the viewing data file 305 (S315).
If it is determined in step S317 that the error level is not “3”, the computer 302 determines that the station code and / or service code of the time immediately before that time is the station code and / or service code of the time immediately after. It is judged whether or not (S323). If the two match, the computer 302 sets the corrected station code and / or service code as “accident (stop)” and describes the correction processing type “E” in the viewing data file 305 (S325). On the other hand, if the two do not match, the computer 302 sets the corrected station code and / or service code to “Unknown” and describes the correction processing type “C” in the viewing data file 305 (S315).
After executing the processes (steps S307, S313, S315, S321, and S325) according to each correction process type, the computer 302 returns to step S301 and continues the subsequent processes.
When the correction determination data file 306 is used, the computer 302 can directly obtain the data of the previous time and the later time from the data of the time above and below the time. On the other hand, when the operation status data file 304 is used, the computer 302 can determine and process the data of the previous time and the later time based on a predetermined unit time.

The fields from “date” to “service code” in the example of FIG. 8 indicate viewing data before correction, and the corresponding correction contents are indicated in “corrected station code” and “corrected service code”. Yes.
For example, the second line (20:01) is an example in which the portion determined to be “Unknown” before correction is corrected using the correction determination data in FIG. 7, and the time 20:00 of the operation status data file 304 is corrected. There is an error occurrence history of error level 2 between 20:00:59 or at time 20:01 of the correction determination data file 306, which is determined as the correction processing type “B” in FIG. It is corrected with the data. The sixth line (21:31) is an example in which the portion determined to be “Unknown” before correction is corrected using the correction determination data in FIG. 7, and the time 21:30 of the operation status data file 304 is corrected. ˜21: 30: 59 or at time 21:31 of the correction determination data file 306, there is an error occurrence history of error level 3, which is determined as the correction processing type “D” in FIG. It has been amended as “unfriendly”. The 10th line (23:11) is an example in which the portion determined to be “Unknown” before correction is corrected using the correction determination data in FIG. 7, and the time 23:10:00 of the operation status data file 304 is corrected. -23: 10: 59 or at time 23:11 of the correction determination data file 306, there is an error occurrence history of error level 1, which is determined as the correction processing type “A” in FIG. Not corrected. In the eleventh line (23:12), the portion determined to be “Unknown” before the correction is between the times 23:11:00 to 23:11:59 of the operation status data file 304 or the correction determination.
