DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data collection system for collecting responses and opinions of a viewer by using a portable terminal owned by the viewer during the broadcast of a viewer participation type program, and a data collection system used in the system. Mobile terminal, a data collection server, and an answer control program.

[0002]

2. Description of the Related Art Among television broadcast programs and radio broadcast programs, there are viewer participation type programs in which viewers participate in discussions and quizzes from outside the station. In this type of program, a viewer answers a question that is asked during or before or after the program is broadcast, and the results are reflected in the program by totaling the answers.

[0003] As a method of collecting the responses of the above-mentioned viewers, for example, (1) a method using telegong, (2) a method using a telephone, (3) a method using a facsimile, and (4) a method using a response server are used. ing.

[0004] In the method based on telegong, for example, in a telecommunications carrier, the number of calls made to telephone numbers corresponding to answer options for telephone program questions is counted for each telephone number, and the result of the counting is notified to the program. Is what you do. For this reason, the broadcast station only has to contract a telecommunications carrier's dedicated line for each program for each program, which is advantageous in that it can be implemented relatively easily. But,
There is a drawback that it is not possible to collect a variety of answers such as attendant opinions of the viewer because the number of calls of the answer is merely counted.

[0005] On the other hand, the method using telephone or facsimile has the advantage that a wider variety of data can be collected because the voices and messages of the viewer can be received directly by the broadcasting station. However, on the other hand, it takes time and effort to rely on humans for data collection work, and the number of viewers who can participate at the same time is limited by the number of contracted lines of the broadcasting station, resulting in poor data collection efficiency. Have a point.

[0006] In addition, the method of using the response server is to transmit the responses of the viewers to the response server of the broadcasting station via a wired public network by using a broadcast receiver with a built-in modem, and to aggregate the responses. Good data collection can be realized. But,
Participants are limited to those who have a broadcast receiver with a built-in modem, and when one broadcast receiver is shared by multiple viewers, only one of them can participate in the program. There is a problem that there are many restrictions.

[0007]

As described above, the methods used in the related art cannot achieve both the diversification of the collected data and the data collection efficiency, and require a special broadcast receiver and require a special broadcast receiver. There are problems such as many restrictions.
