  The present invention relates to a receiving apparatus that receives a community channel of a cable television station that voluntarily broadcasts information and the like necessary for local residents, and in particular, can receive and display a transmission signal of a broadcasting system corresponding to digital television broadcasting. It relates to the device.

Currently, as an information service for local residents, it is transmitted to television receivers marketed in the same manner as terrestrial analog broadcasting. There is also an advantage that the viewer can easily select the transmission channel by using a terrestrial broadcast channel. For example, in the Kanto area,
From NHK General Broadcasting Channel 1 to 3, 4, 6, 8, 10 and 12 channels, such as 5 channels and 9 channels, which are not terrestrial analog broadcasting, such as community channels of cable TV stations called voluntary broadcasting, and services to local residents Provides information services.

In recent years, digitalization has progressed in the broadcasting field such as BS digital broadcasting and terrestrial digital broadcasting, and television receivers that are compatible with digital broadcasting have been sold. The current terrestrial analog broadcasting is scheduled to end in July 2011, and only digital broadcasting will be provided. It is presumed that commercially available television receivers cannot receive terrestrial analog broadcasts at that time.

Under such circumstances, there is a risk that information services to local residents or services such as community channels of cable television stations that are currently being transmitted to television receivers marketed in the same manner as terrestrial analog broadcasting may not be possible. There is.

Also, in BS digital broadcasting, it is possible to effectively use radio waves that can be transmitted by a plurality of broadcasters to one transponder. However, since a desired broadcaster cannot be selected simply by selecting a transponder, for example, “Patent Document 1” As in "Digital broadcast receiver remote control device and digital broadcast receiver", viewers can directly select the program of the business that they want, and instantly recognize the program currently broadcast to the viewer Thus, this problem is solved by providing a digital broadcast receiver remote control device and a digital broadcast receiver that enable program zapping.

In addition, for example, Patent Document 2 discloses a technique for reducing the amount of information transmitted by uniquely assigning a network ID to each of the transmission masters throughout Japan in terrestrial digital broadcasting including audio.
Proposed in “Digital Terrestrial Broadcasting Transmission / Reception System and Digital Terrestrial Broadcasting Reception Device”. Patent Document 2 discloses that “P transmitted in parallel with program information in digital terrestrial broadcasting”.
SI (Program Specific Information) / SI (Service
ce Information) is defined by the Association of Radio Industries and Businesses (ARIB) as supplementary information for selecting a program or acquiring program information.
These need to be transmitted. Is also described.

  The operation of digital terrestrial television broadcasting is described in the technical document TR-B14 “Regulation for Operation of Digital Terrestrial Television Broadcasting” (Non-Patent Document 1) of the Radio Industries Association (ARIB). There is a function for assigning each operator by default to the buttons (1) to (12) equipped in the broadcast receiver remote controller, and one operator is assigned to the corresponding button with the number described in the remote_control_Key_ID. " It has become.

As described above, when a remote_control_Key_ID to which a digital terrestrial broadcasting business operator should be assigned is sent to the buttons (1) to (12) equipped on the remote controller of the receiver and set by default, the community of the cable television station When services such as channels and information services for local residents are performed on empty channels as they are now, it is not possible to set buttons for remote channels (1) to (12).
