Description

  The present invention relates to an information receiving apparatus, an information receiving method, an information receiving program, and an information distribution system.

In recent years, in digital broadcasting such as terrestrial digital broadcasting and BS (Broadcasting satellite), an electronic program guide (EPG: Electric) showing the contents of programs to be broadcast.
onic Program Guide (hereinafter simply referred to as “EPG”). Various proposals have been made to improve the convenience on the viewer side by utilizing this EPG information. For example, using this EPG information, it has been proposed to reserve printing only program-linked broadcast data to be provided, or to perform reserved printing separately from the moving image data of the program (see Patent Document 1). .

When using this EPG information to watch a program with an in-vehicle digital broadcast receiver,
It has been proposed to display a unique electronic program guide grouped for each viewer and to reflect information corresponding to reception sensitivity in the unique electronic program guide (see Patent Document 2).

Also, ADMS (TV-Asahi Data And Multimedia Se
rvice) -EPG and iEPG are also known which provide EPG information via the Internet, and EPG information received via the Internet and EPG received from broadcast waves.
Proposals have also been made for control when information is received (see Patent Document 3).

JP 2007-235639 A (summary, paragraph [0013], etc.) JP 2007-89220 A (summary, paragraph [0007], etc.) JP 2008-252447 A (summary etc.)

However, in the techniques disclosed in Patent Documents 1 to 3, when the viewer starts broadcasting when there is a sweepstakes or present announcement in a program scheduled to be broadcast or in a currently broadcast program, for example. I can't know if there are any sweepstakes or gift announcements. In addition, other broadcast programs are being watched, and it is impossible to know whether there is a sweepstakes or a notification of a present in the switched program when channel selection is switched. In addition, when there is an announcement of a prize in a program, the viewer cannot know information that the application period of the prize is high in real time only during program broadcast, for example, and the deadline for application. Also, when making a recording reservation for a program, a person who wants to make a recording reservation cannot know information such as the presence or absence of a prize for the program that is to be reserved, and the application period when there is a prize. . Therefore, when viewing the recorded program later, even if the applicant wishes to apply for the sweepstakes, the application period for the sweepstakes has passed, and there may be cases where it is not possible to apply for the sweepstakes.

Therefore, in view of the above-described problems, the present invention can easily grasp information notified in a broadcast program and can contribute to an increase in the audience rating of the broadcast program, an information reception method, and an information reception program. And an information distribution system.

An information receiving apparatus according to an aspect of the present invention includes an output processing start determination unit that determines whether or not content output processing has been started, and content that has been determined that output processing has been started by the output processing start determination unit When the notification information presence / absence confirmation unit confirms the presence or absence of specific notification information and the notification information presence / absence confirmation unit determines that there is notification information, information indicating that there is notification information and / or information related to the notification information is output.
