Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast receiving apparatus and a program information presenting method, and more particularly to presenting information of a program in broadcasting where event sharing is performed.

[0002]

2. Description of the Related Art In CS digital broadcasting, a display for presenting only the current program and only the next program is performed. This is characterized in that the display content can be reduced and the display area can be reduced as compared with the so-called EPG such as the latte column format, and the obstruction of viewing and listening to the broadcast can be reduced.

Event sharing is defined in BS digital broadcasting, and main broadcasting has started in December 2000.

CS digital broadcasting or BS as described above
In a conventional digital broadcast receiver that receives a digital broadcast, an input device such as an operation button provided on the receiver body or a remote controller (remote control) for operating the receiver from the outside is operated by a user and received by an antenna. The digital signal was tuned in by the tuner and the broadcast was watched. Further, a desired digital signal is extracted and acquired by the data extraction device and stored in the data storage device, and the information of the SI data, which is one of the data stored in the data storage device, is multiplexed on the broadcast video, It could be displayed on an integrated or external display device.

Here, information (presentation time, program name, etc.) of present / following EIT of some channels among SI data is superimposed on the video of the broadcast by using a multiplexing device or the like and displayed on the display device. In addition, it is possible to switch channels to be displayed and selected by operating a cursor key or the like, to tune in a selected program in the current program display, and to view / record a program in the next program display.

However, the conventional digital broadcast receiver has a problem that the event sharing information is not presented in displaying the current program and the next program.

[0007]

As described above, the conventional digital broadcast receiver has the following problems in displaying the current program and the next program.
Event sharing information was not presented.

For example, Japanese Unexamined Patent Application Publication No. 9-191236 discloses a technique for satisfactorily coping with an unreceivable state at all recognized reception frequencies within the same network. Also, Japanese Patent Laid-Open No. 2000-2362
In No. 73, PAT and /
Alternatively, there is disclosed a technique for correctly displaying receivable services even when the EIT and NIT are different.
However, these suggestions do not provide information for event sharing.
