Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and more particularly to a television receiver capable of receiving at least digital satellite broadcasting such as CS broadcasting.

[0002]

2. Description of the Related Art In a digital satellite broadcasting system such as CS broadcasting, for example, a large number of channels of 70 or more are prepared and a large number of programs are provided. In this system, guide information of a program currently being broadcast and a program to be broadcast in the future is transmitted at predetermined time intervals together with the original program data. A television receiver capable of receiving digital satellite broadcasting has a function of displaying a program guide screen (program guide table) based on program guide information.

In such a television receiver, for example, a part of the program guide table corresponding to the received all program guide information is displayed on the program guide screen.
On the program guide screen, for example, a plurality of program guides are displayed in a matrix with the vertical axis as the time axis and the horizontal axis as the channel number axis. For example, programs for three channels, which are for three hours, are displayed on the program guide screen.

On the program guide screen, a program can be designated,
A cursor for scrolling the program guide screen is displayed. This movement of the cursor is performed by operating the cursor movement key. Each time the cursor moving key for moving up or down is operated, the cursor moves in the time axis direction. In addition, the cursor moves in the channel axis direction each time the cursor moving key for moving left or right is operated. Then, when the cursor moves to the end of the program guide table displayed on the program guide screen, the program guide screen is scrolled. When the program to be selected is selected by the cursor in the program guide table displayed on the program guide screen and the enter key is pressed, the program selected by the cursor is selected.

By the way, television receivers capable of receiving terrestrial broadcast programs, BS broadcast programs and CS broadcast programs have been developed. An operation unit such as a remote control transmitter in a television receiver is usually provided with 12 terrestrial broadcast program tuning keys and 8 BS broadcast program tuning keys. However, since the number of channels in a CS broadcast program is very large, a program channel selection key for each channel is not provided. Therefore, the channel selection in the CS broadcast program is performed on the program guide screen or by the channel skip key, but in either case, there is a problem that the channel selection takes time.

[0006]

SUMMARY OF THE INVENTION According to the present invention, in a television receiver capable of receiving at least a BS broadcast program and a CS broadcast program, the BS program tuning key is used as a preset key of a channel number for the CS broadcast. An object of the present invention is to provide a television receiver that enables the channel selection of a specific range of channels in a CS broadcast program in a short time.

[0007]

A first television receiver according to the present invention is a television receiver capable of broadcasting at least a BS broadcast program and a CS broadcast program.
Preset setting means for allowing the user to preset a channel number for CS broadcasting to the S program tuning key, and when the BS program tuning key is operated by the user while the CS broadcast program is being tuned A channel selection means for selecting a CS broadcast program based on a channel number for a CS broadcast preset in the operated BS program selection key is provided.

A second television receiver according to the present invention is a television receiver capable of receiving at least BS broadcast and CS broadcast, for allowing a BS program tuning key to preset a channel number for CS broadcast by a user. Preset setting means, storage means for storing a channel number for a CS broadcast preset in a BS program tuning key in a storage device, preset valid / invalid setting means for allowing a user to set a preset valid mode or preset invalid mode, CS broadcast Program selected
In case the time in and preset enable mode is being set, if the BS program selection key is operated by the user, the channel number for CS broadcasting is preset to BS program selection key operated From the storage means, and a first tuning means for tuning a CS broadcast program on the basis of the read channel number for the CS broadcast; and a preset invalid mode when the CS broadcast program is selected. When the BS program tuning key is operated by the user during the operation, the reception mode is changed to the BS broadcast reception mode, and the BS program tuning key is operated based on the operated BS program tuning key.
A second channel selecting means for selecting a broadcast program is provided.

[0009] The user stores in the storage device the favorite channel setting means for setting a predetermined number of channel numbers as the favorite channels among all the channel numbers of the CS broadcast, and the channel numbers set as the favorite channels. A storage means is provided to allow the user to select an automatic setting mode and a manual setting mode as the preset setting means. When the automatic mode is selected, the channel number set as the favorite channel is set to the BS. It is provided with means for automatically presetting to the program tuning key and means for presetting a predetermined channel number to the BS program tuning key based on the manual setting by the user when the manual setting mode is selected. It is preferable to use one.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is applied to a television receiver capable of receiving terrestrial broadcasting, BS broadcasting and CS broadcasting will be described below with reference to the drawings.

Programs provided by CS broadcasting include C
There are free programs that can be viewed free of charge by paying a system usage fee such as a fee for joining the S broadcasting system and a basic fee, and pay programs that are charged separately from the system usage fee. In addition, pay programs include those purchased in advance for each channel and those charged only when viewed (PPV: pay per view). In order to watch a PPV program, it is necessary to perform a purchase procedure on the television screen before the program starts or when the program is being broadcast.
