Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for individually examining the program orientation of a plurality of viewers / listeners, such as radio and television broadcasts, in a characteristic parameter extracted from continuous musical tones output from a broadcast receiver. And the characteristic parameters of the continuous tone output from the reference broadcast receiver, and the broadcast service use state for specifying the program being viewed / listened based on the reception frequency and time when they match. Recording technology.

[0002]

2. Description of the Related Art When investigating the state of use of a conventional television broadcast service, a viewing program collector is mounted on a broadcast receiver to detect a local transmission frequency leaking from the broadcast receiver, and to determine a reception time and a local transmission frequency. The frequency was recorded and transferred to a program rating center via a telephone modem built in the viewing program collector, and the ratings were totaled. With this method, the audience rating can only be grasped by households, and it has not been possible to grasp the audience behavior of each member of the family and to aggregate the audience rating.

[0003]

SUMMARY OF THE INVENTION In order to count the individual audience rating, a method of recording the viewed and listened programs, or, in the case of television broadcasting, channel detection by the television broadcasting receiver of the household to be surveyed. Set up a bowl and have the whole family press a button for yourself when watching a television broadcast. When the channel is changed, it is recorded automatically. The data measured every minute is sent to a program rating center via a telephone line, but an infrared sensor is used to prevent omissions or forgetting to press.
A method of discriminating a person coming in front of a broadcast receiver by using such a method has been studied, but sufficient judgment cannot be made, and it has not been put to practical use. Even if the household viewing rate can be calculated, it is difficult to accurately calculate the individual viewing rate. In particular, the only method of measuring the radio listening situation for each individual is a diary-type entry method, which is likely to cause omissions or errors, and also limits the survey period. For this reason, there has been a problem that an enormous amount of time is required for collecting data. It is difficult to sum up the individual listening rates of radio broadcasts, which often include portable receivers, by a method of closely attaching a viewing program collector to a broadcast receiver.

[0004]

In order to achieve the above object, the personal audience rating collecting system according to the present invention records and analyzes a musical tone from a broadcast receiver, specifies a receiving frequency, and receives a program from the receiving frequency and a program. A watch program collector capable of recording the time in memory is carried in the form of a wristwatch or a pendant for each of a plurality of survey subjects, and the reception frequency recorded in the watch program collector every time the battery of the watch program collector is charged. A personal viewing rate totalizing system for collecting personal viewing percentages by sending digital data relating to time and time to a program rating totaling center via a telephone modem and a telephone line with a built-in charger. The viewing program collector reduces power consumption and reduces size by narrowing down only the basic functions and digitally processing the music from the broadcast receiver, making it easier for individuals to carry.

The reception frequency and the time of the clock 202 when the matrix patterns of the two musical tones coincide with each other are recorded in the program memory 208. When the watched program is to be checked again after a certain period of time, the program is checked from the reception frequency that was previously viewed and listened to.If the same as above, the check is terminated and the program is regarded as continuation of the program. If the program is different, a new reception frequency is specified by following the above procedure. Thereafter, the survey is continued at regular intervals, and when the battery of the viewing program collector 200 runs out, the survey subject connects the charging terminal 220 to the charging terminal 302 in FIG. When the input voltage of the power supply circuit 210 rises, the data processing circuit 207 reads out the contents of the program memory after a lapse of a certain time, and outputs it to the interface X209.
