Description

  The present invention relates to a broadcasting system, a receiving apparatus and a program used for digital broadcasting, and in particular, a broadcasting system and a receiving apparatus capable of restricting the use of a broadcast program when the premise information of the broadcast program is cut on the viewer side. And the program.

  In general, broadcast stations such as terrestrial broadcasts transmit broadcast programs so that they can be viewed free of charge, while inserting commercials provided in the middle of broadcast programs to produce programs from commercial providers that provide such commercials. The cost etc. are obtained.

  That is, a broadcast program is broadcast free of charge with the cooperation of a broadcasting station and a commercial provider on the premise that it is viewed together with the commercial.

  In other words, the commercial cut phenomenon in which the viewer switches to another channel at the time of commercial or the commercial cut function installed in a video recorder or the like deletes the commercial and records / plays it breaks the important premise described above. Leads to. This type of commercial cut phenomenon is not particularly effective, but it requires a complicated operation on the viewer side, so it is less frequent and is not considered a problem.

  However, when terrestrial broadcasting is shifted to digital broadcasting, it is technically easy to distinguish between broadcast programs and commercials, so the commercial cut function can be widely used in viewer-side equipment. There is sex.

  In addition, hard disk recorders that record digital broadcasts have a commercial cut function and are expected to be widely used in the future, which may lead to serious problems.

  As described above, in digital broadcasting, it is easy to distinguish between a broadcast program and a commercial, and there is a possibility that the commercial cut function will spread to viewer-side devices.

  However, since this type of commercial cut function leads to breaking the important premise of free broadcasting that the commercial is viewed, it is desirable that the broadcast station side and the commercial provider side prevent it.

  Similar to this, there is known a prize solicitation program in which a problem that can be understood by a viewer who has watched a broadcast program is given at the end of the program, and the answer is used as a prize application condition.

  In this case, viewing the program is an important premise, but there are circumstances where the broadcasting station cannot give a very difficult problem. For this reason, there is a possibility that a person who creates an answer by viewing only the application part of the sweepstakes without viewing the program will appear.

  In either commercial cuts or sweepstakes application programs, the same benefits as viewing the premise information can be obtained even though the viewer does not view the premise information of the broadcast program. However, it is desirable for the broadcasting station side to prevent this.

  The present invention has been made in consideration of the above circumstances, and provides a broadcasting system, a receiving device, and a program that can restrict the use of a broadcast program when the premise information of the broadcast program is cut on the viewer side. Objective.
