DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general analog T
This is a technique relating to channel selection means in a receiver capable of receiving a plurality of broadcasts such as a V broadcast and a satellite broadcast, and a receiver which receives a broadcast in which a plurality of programs are transmitted from one broadcast station such as a digital broadcast. .

[0002]

2. Description of the Related Art As a conventional technique, a case where a program is selected by a digital broadcast receiver will be described. For example, in a U.S. digital broadcast, a major channel corresponding to a broadcast station and
By setting a minor channel equivalent to a program,
A predetermined program is selected.

As a specific method of selecting a channel in a digital broadcast receiver, when a general remote controller having a numeric key and an up / down key is used to select a channel, similarly to analog broadcasting, "XX.YY" is used. ", Major channel number XX and minor channel number Y
A method of directly selecting Y and directly selecting a channel, or a method of sequentially switching programs by using a channel up / down key to select a channel can be considered. In each case, a plurality of key operations are required.

In order to improve the operability, a method using a cross cursor key has been proposed. In this method, first, a channel is displayed on a television screen, and the channel is selected by selecting the channel with the cross cursor key. However, in this channel selection method, there are two actions of displaying and selecting, and the operability is poor.

Japanese Patent Laid-Open Publication No. H11-164216 proposes a method of solving this problem, enabling tuning with a simple operation, and improving operability when selecting a multi-channel. . The publication describes a tuning circuit for selecting a television broadcast signal, up / down / left / right cursor key input means for selecting and inputting up / down / left / right by manual operation, and a virtual position array as a storage area. A memory for storing channel data selectable in the virtual position array; and a designated position movable up, down, left, and right in the virtual position array based on operation of the up, down, left, right cursor key input means. A control circuit for selecting the channel data stored in the virtual position of the position to the tuning circuit, and fetching the selectable channel data and arranging the virtual data in the virtual position, for example, arranging adjacent channels on the left and right. Is
This is an invention that enables channel up / down with left / right cursor keys and skips several channels with up / down cursor keys to improve the efficiency of channel selection. In addition, the arrangement of virtual positions is arranged so that frequently viewed programs are arranged close to each other, or channels are classified and arranged by category. It has also been proposed to increase the efficiency of channel selection by switching channels within a category by a selection operation.

[0006]

However, compared to analog broadcasting and current satellite broadcasting, digital broadcasting is one of the problems.
By broadcasting several programs at a broadcasting station, the number of programs is multiplied by several times.In the conventional sequential channel selection method, it is inefficient to select a target program from a large number of programs. Key operation is inevitable.

[0007] Further, it is impossible to achieve a significant improvement in efficiency in the channel selection method using the cross cursor keys or the skipping method described in Japanese Patent Application Laid-Open No. H11-164216. When the number becomes huge, there is a problem that it is impossible to display the virtual position array by OSD, or that the tuning operation is complicated.

According to the present invention, a broadcast station and a program are associated with up / down / left / right operations of a cross cursor key, respectively, thereby greatly improving the efficiency of the channel selection operation and grasping the number of receivable broadcast stations and the number of programs. It is another object of the present invention to provide a broadcast receiving apparatus that is more operable in combination with direct input and skip operation by displaying an OSD and using it together with numeric key input.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a broadcast receiving apparatus having at least a cross cursor key and a number key for selecting a broadcast program on a remote controller and / or a main body of the apparatus. By assigning the operation to the selection of a broadcasting station and the left / right operation of the cross cursor key to the selection of a program and associating the operation with the up / down / left / right operation of the cross cursor key, respectively, a great improvement in the efficiency of the tuning operation can be achieved. It was done.

Further, according to the present invention, the channel selection by the numeric keys is assigned to the direct channel selection of the broadcasting station or the direct channel selection of the program. This enables skip operation.

Further, according to the present invention, the number key operation within a certain time after the interruption of the up and down operation of the cross cursor key is directly selected for the broadcasting station, and the number key operation within a certain time after the interruption of the right and left operation of the cross cursor key is not performed. By directly assigning a channel to a program, a skip operation can be performed in combination with a cross cursor key without a special switching key operation.

Further, the present invention has a receivable broadcast station information extracting means, a receivable program information extracting means, and an OSD display means, and performs OSD display for channel selection guide at the time of channel selection operation. Further, the operability at the time of tuning is further improved.
