2. Description of the Related Art In recent years, the number of channels has increased due to satellite broadcasting, cable television, and the like, and it has become difficult to select programs because of the increase in viewer options. For this reason, programs scheduled to be broadcast from now on are broadcast as electronic program guides. Currently, in digital broadcasting, an electronic program guide called an EPG is broadcast, and a terminal that has received the program guide displays the program guide or controls a linked VTR to perform recording.

Further, with the development of networks and mobile terminals, it has become possible to make video program reservations in the computer network environment, which have hitherto relied on human power.
As such an apparatus, for example, Japanese Patent Laid-Open No. 9-10282
There is a remote control device and a communication device described in Japanese Patent Laid-Open Publication No. 7-1995. The mobile terminal accesses the server that stores the program information from the mobile terminal via the network, and refers to the information for recording reservation, such as a program table with the broadcast channel of the program, the broadcast start time, and the end time. Check the broadcast channel and broadcast time of the program to be reserved.
The user inputs the information to the mobile terminal, and the input information is transmitted to the home VTR via the network, and the VTR executes the reservation to record the information.

[0004]

However, in the case of such a reservation setting based on a broadcast time, an appropriate reservation recording cannot be performed when a broadcast time is changed due to an extension of a night game relay or insertion of a special program. In addition, in the current program broadcasting, there are overwhelmingly many regular programs such as broadcasting drama 10 times continuously from 7:00 to 8:00 every Friday, so it is not possible to watch the main broadcast, and recording If you miss an episode in the middle of the drama because you can't do it, you won't be able to connect the story, you will not be able to understand the content, and there will be problems such as distracting the drama.

[0005] Also, regarding rebroadcasting, whether or not to rebroadcast is artificially determined by an authorized person based on the audience rating and the like. Also, although there is a plan to improve the audience rating, at the moment it is just a number that tells whether the TV was on, but it is not clear whether it is a program that you want to actively watch However, the number of viewers who think "I couldn't watch the program but want to watch it" because I missed it has no idea.

[0006] As described above, including the above problems, The program cannot be recorded unless the user makes a recording reservation correctly. 2. At night, there are few people who watch programs, so the number of programs per channel cannot be increased. 3. Since it takes time to reflect the viewer's popularity, it takes time until the rerun is decided.

[0007] 4. Audience ratings are expensive and cannot be surveyed if questions arise. 5. Despite the large number of potential viewers, the program is not broadcast because the number is not known. And so on. Therefore, the present invention enables a program to be transmitted from a viewer to a broadcasting station at any time, thereby enabling a program configuration that quickly reflects the popularity of the viewer, and also by transmitting program reservation information to the viewer in a simple and reliable manner.
