First, in the general transmission confirmation process that has been made up to now, the broadcaster directly checks / listens (or records / records) the contents of the broadcasted broadcast and checks whether or not it is transmitted. In addition, the method of processing by the delivery confirmation agency is similar. However, since most of the transmission confirmation process is made by hand, there is a problem that the probability of error is high and wastes time and time.
On the other hand, in the audience rating survey, there are a survey or a feature data detection survey method, but the former (survey) is rarely used, and the latter (feature data detection survey) uses the feature data from the broadcast. The audience rating is detected by comparing with the control data stored in the database.
For example, the Picture Matching Method, which is one of the latter (characteristic detection detection) methods of TV viewing rate investigation method, is used for matching data (30 frames specified for each frame) of broadcasts transmitted by all TV media. After storing the three 赤 / 綠 / 원 three primary color data in the database, it detects the broadcast data of the same condition output from the TV to be investigated, and compares it with the control data and the frame, and these data are checked for a certain time. If the match is longer than 6-15 seconds, depending on the company, the same broadcast is considered to be used as a viewership survey. However, if the channel of the receiver under investigation is changed during the investigation or if any data is wrong due to mechanical error, the detected data during the confirmation time (6-15 seconds) is treated as the viewer rating of the other program (or the previous viewing program). This situation occurs whenever the channel of the receiver under investigation is changed. However, even a short time of 6-15 seconds can cause serious errors in broadcasts (eg commercials) with short lengths and heavy channel movement.
Finally, the transmission confirmation and audience rating survey described above are currently being conducted by different organizations (or systems), which is a double burden on the industry.
The present invention is to solve the above-mentioned problems of the prior art, and inserts the information code and the sequential code into a predetermined portion of each frame of the broadcast, and then transmits the information code to the sender, and then the information code and The purpose of this is to detect the sequence code and to obtain the correct rating check result and the result of the viewer rating survey without error due to the channel change of the viewer (or the listener, `` viewer ''). It aims to integrate rating surveys into one system.
As a means for realizing the above object, the present invention inserts an information code and a sequential code into a predetermined portion of each frame of a broadcast, transmits the information code to the sender, and transmits the information code and the sequential code from the transmitted broadcast signal. The present invention proposes an integrated system for broadcasting transmission confirmation, viewer rating investigation and its method using a sequential code for each frame that detects and stores the result in a server, and then calculates the transmission confirmation and rating survey using the data stored in the server.
More specifically, in the present invention, the producer, the sender, the user of the data and the broadcast receiver that is installed in the receiver under investigation (hereinafter, referred to as a "receiver") for receiving and outputting a broadcast signal, transmitting an information code, a sequential code, and a broadcast.

Show that it was detected.
Finally, the system server 5 calculates the transmission confirmation and the audience rating data using the data stored in the server DBs 6 and 7 by using the built-in processor, and transmits the data to the data user 8.
The transmission confirmation above checks the transmission (or omission) for each frame by comparing the total number of frames of the broadcast stored in the system server with the detected sequential code, and the viewer rating is calculated using the following viewer rating calculation formula.
Calculation formula: Viewership (%) = A / (B x C) x 100
In the above viewer rating calculation formula, A, B, and C are 'the sum of the number of frames having the same information code / sender code detected in all detectors for a certain time' stored in the server DB 6, 7. Number ',' the total number of detectors'.
Based on the configuration described above, step-by-step description of the integrated method of broadcasting broadcast transmission confirmation, audience rating survey using the frame-by-frame sequential code of the present invention as follows.

In the second step, when the broadcast signal transmitted by the sender 2 is output through the output device 3-2 of the receiver 3, the detector 4 installed in the receiver 3 causes the information code in the broadcast signal. And the sequence code is detected by the channel adjusting unit 3-1, and then transmitted to the system server 5 by adding the corresponding detector ID to the detected data.
In a third step, the system server 5 adds the date and time transmitted to the data transmitted by the detector 4 to the system server 5 using the built-in processor, and stores the data in the server DB 6 and then stores the system. Using the data stored in the server, the results of transmission confirmation and viewership survey are calculated and transmitted to the data user (8).
The system server uses a processor included in the system server to identify an information code, which is a unique code of a corresponding broadcast, for identifying each broadcast in a certain portion of each frame of the broadcast transmitted by the producer, and to identify the frame of the broadcast. After inserting the sequential code, which is the serial number of the frame, the broadcasting code and the related material with the information code and the sequential code inserted are stored in the server DB, and the broadcasting with the information code and the sequential code inserted is transmitted to the sender. A first step of transmitting to a self receiver;
When the broadcast signal transmitted by the sender is output through the output device of the receiver, an information code and a sequential code inserted in each frame of the broadcaster and a sender code for identifying the sender who transmitted the broadcast are output by the detector installed in the receiver. A second step of adding the detector ID, which is a unique ID of the detector that detected the data, to the system server after the detection;
The system server stores the data in the server DB by adding the date and time when the data is transmitted to the system server to the information code, the sequential code, the sender code and the detector ID received from the detector using the processor included in the system server.
