Abstract

PROBLEM TO BE SOLVED: To display analog broadcast program information that is broadcasted in a digital broadcast program by reading channel selection information which has been stored so as to receive a channel where an analog broadcast program list information is multiplexed and broadcast, thereby selecting an analog broadcast program list in place of an analog broadcast program and displaying the list. SOLUTION: When a program list display instruction is made from a remote controller 13 while viewing an analog broadcast program, a control section 9 extracts channel selection information, which has been stored in advance in a channel selection information memory 11 and sets the information to a digital channel selection section 5. At the same time, the control section 9 instructs the reception of program reception related information to a separate section 6, extracts channel selection information to receive program list information from the received program reception related information and information to separate it, and instructs channel selection to the digital channel selection section 5 to the separate section 6. A decoding section 7 generates a program list mainly concerning the analog broadcast program which is viewed, based on the analog program list information separately received and allows a switch 8 to select the list for its display.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television broadcast receiving apparatus.

[0002]

2. Description of the Related Art In a conventional television broadcast receiving apparatus,
Analog broadcast programs such as terrestrial broadcasts, BS broadcasts, and CS broadcasts can be received. There are also devices that receive CS digital broadcasts.

[0003] Digital broadcasting has a plurality of channels for broadcasting, and a plurality of programs can be multiplexed and broadcast on one channel. Information on program reception such as correspondence between program numbers and programs, correspondence between programs and channels, and information for receiving channels is also sent at the same time. If a program number is specified, program reception-related information is received. Thus, a program can be selected. Furthermore, in order to facilitate program selection, program guide information is simultaneously broadcast, and a receiver uses a method of creating and displaying a program guide from this information, selecting a program guide from the program guide, and receiving a program.

[0004] The program guide information is digital broadcast program guide information, but analog broadcast program guide information can also be transmitted.

[0005]

However, in the conventional television broadcast receiving apparatus, when the analog broadcast program guide information is transmitted by digital broadcasting, the program guide information cannot be received, displayed, and controlled.

[0006]

In order to solve the above-mentioned problems, according to the present invention, when a program guide display instruction is given while an analog broadcast program is being watched, the channel selection information stored in advance is read out and the analog After receiving, separating and decoding a channel on which broadcast program guide information is multiplexed and transmitted, an analog broadcast program is switched to an analog broadcast program guide and displayed.

[0007] This makes it possible to display analog broadcast program guide information transmitted by digital broadcasting.

[0008] The present invention is also configured so that an analog broadcast program table is superimposed on an analog broadcast program and displayed.

[0009] This makes it possible to display analog broadcast program guide information transmitted by digital broadcast overlaid on the analog broadcast program.

Further, the present invention selects one program from the program guide while viewing the analog broadcast program guide, reads out the channel selection information stored in advance, and receives and displays the selected program. It is composed.

Thus, even when analog broadcast program guide information is transmitted by digital broadcasting, a program to be viewed can be easily selected from the analog broadcast program guide.

Further, the present invention is configured to monitor time and automatically switch to and display an analog broadcast program guide when a program end time comes, or to superimpose a program guide on a program.

[0013] This allows the viewer to select the program to be viewed next without instructing the display of the program guide at the end of the program.

Further, the present invention is configured to monitor the channel change frequency of a viewer watching an analog broadcast program, and to automatically display a program table being viewed.

Thus, even if the viewer frequently changes channels, unnecessary channel changes can be eliminated by displaying the program guide.

[0016]
