BACKGROUND OF THE INVENTION
The present invention relates to a reception control apparatus for a temporary broadcast service in a broadcast reception apparatus.
[0002]
[Prior art]
A transmission signal formed by mixing a regular broadcast service channel broadcast regularly and a temporary broadcast service channel broadcast irregularly is transmitted as a radio wave such as a satellite wave or a terrestrial wave, or a cable TV Broadcast reception that allows a receiver to receive a transmission signal transmitted to a wired line that supports optical transmission such as electrical transmission and optical cable, and select and view a desired channel from a desired regular broadcasting service and extraordinary broadcasting service The device is widespread.
[0003]
In recent years, a broadcasting service called BS digital broadcasting has appeared, and according to this, a huge amount of channel information can be included in one transmission signal by a highly advanced digital multiplexing system. It is like that.
[0004]
As for these enormous channels, channels for regular broadcasting services that are broadcast regularly and channels for temporary broadcasting services that are broadcast irregularly are allocated to many broadcasters.
[0005]
The temporary broadcasting service is a service that is performed in a temporary organization and is used in emergency news programs such as major accidents and disasters. This is done by forming a new temporary channel in the margin band obtained by reducing the bit rate while maintaining the original regular broadcasting service organization service. For this reason, regular broadcasting services are not provided on the temporary channel, and it is implemented several times a month, and the implementation date and time is completely uncertain. Yes.
[0006]
In BS digital broadcasting, since the number of channels of broadcasting services is enormous, it is difficult to select a receiving channel with the same feeling as in the case of analog TV broadcasting as before, and many broadcasting A desired program is selected by using an electronic program guide called EPG which displays a list of programs, and the EPG data is multiplexed and embedded in the original transmission signal, and is provided with a special broadcasting service. The content of is not included, only the content of the regular broadcast service is expressed.
[0007]
In addition, when the special broadcast service is started, the user is notified by announcement or supermarket during the regular broadcast service program of the broadcaster of the special broadcast service. The viewed user can view the desired special broadcast service by inputting the channel number data of the special broadcast service as, for example, three-digit numeric data and directly selecting the channel.
[0008]
[Problems to be solved by the invention]
Since the conventional broadcast receiving apparatus displays a notification that the special broadcast service has been started on the screen of the regular broadcast service, the user who sees this displays the channel data (for example, a number) of the corresponding special broadcast service. Since the user can watch by manually performing the operation of inputting the three digits), the user is burdened with the operation burden.
[0009]
In addition, when an emergency news program in the event of a large-scale incident or disaster occurs as an extraordinary broadcast service, the same type of emergency news program is also performed by the other broadcasters. There is a high possibility.
[0010]
However, since there is no guarantee that the presence of the temporary broadcast service is reflected in the electronic program data, if the user does not receive an announcement during reception of the regular broadcast service, the broadcaster will provide the regular broadcast service. The channel of the broadcaster's regular broadcast service is received once, and it is determined whether or not the temporary broadcast channel is started within the broadcast. After confirming the presence of the special broadcast service by the judgment, it is possible to view the desired special broadcast service by inputting the channel number again. It was inferior to.
[0011]
Therefore, an object of the present invention is to notify the user that the special broadcast service is being implemented without receiving the normal broadcast service, and among the many channels forming the regular broadcast service and the special broadcast service. It is an object of the present invention to provide a reception control device for a temporary broadcast service in a broadcast reception device that can quickly select and listen to a desired channel of the temporary broadcast service.
