Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to means for selecting a TELETEXT character information program in a television receiver with a TELETEXT function.

[0002]

2. Description of the Related Art TELETEXT broadcasting is a teletext broadcasting mainly performed in Western Europe. First, the TELETEXT broadcasting will be briefly described. In the TELETEXT broadcasting, as shown in FIG. 10 (A), a series of character information programs are cyclically transmitted together with a conventional television signal. The viewer obtains necessary character information by selecting a desired character information program from the character information programs and displaying the selected character information program on the display.

As shown in FIG. 10 (B), each program is made up of a page with one screen as a unit, and is usually composed of a plurality of pages. The information on each page is shown in Figure 10.
As shown in (C) and (D), within a vertical blanking period of a video signal of two fields, data blocks called data packets are dispersed and transmitted in a portion outside the vertical synchronization period. . In addition to page information, the data packet also includes various control information for FLOF service, etc., which will be described later (reference [SPB 492 TELETEXT SPECIFICATIO
N] Europian Broadcasting Union, published in December 1992).

In the conventional television receiver (receiver) with the TELETEXT function, the FULL-LEVEL-ONE FEA is used to specify the page on which the desired character information program is displayed.
A simple page selection method called TURE (FLOF) mode,
There are two types of modes (direct input mode) in which the numerical value of the desired page is directly input.

FLOF is a service provided by a broadcasting station for simple page selection. When the FLOF service is provided, as shown in FIG. 12, the display (1
9) Above, the classification of programs of TELETEXT broadcasting [SPORT] [AAA] [BBB]
[CCC] is displayed in [RED] [GREEN] [YELLOW] [CYAN] color letters. On the other hand, the remote controller for operation (remote control transmitter) has [RED] key (21), [GR]
EEN] key (22), [YELLOW] key (23), and [CYAN] key (24) color keys (25) are arranged so that the viewer can select the program he / she wants to select from the receiver (1). By pressing the color key (25) having the same color as the color of the characters displayed on the display (19), the TELETEXT program desired to be watched is selected. The colors of the color key (25) and the colors of the numbers corresponding to the colors on the display (19) are the above four colors according to the service and regulations, but it is of course possible to change the colors and make them monochrome. Is. An example of the FLOF service is shown in FIG. 12, in the title page of page 105, [SPOR
To select [T], press the [RED] key on the remote control transmitter (2).
Press (21). A display screen example of this result is shown in FIG. The title of [SPORT] is recorded on page 180, and the sports names such as [BASEBALL] and [SOCKER] are individually displayed in the lower column. Select and press the color key (25) of the desired sport. Good. As mentioned above, the viewer can easily
The FLOF service is a service provided by the broadcasting station so that TEXT programs can be selected.

In the direct input mode, as shown in FIG. 11, 0 to 0 also arranged on the remote control transmitter (2) are used.
Either the numeric keypad (26) of 9 was used to enter the page of the desired text, or the [UP] key (27) and [DOWN] key (28) were used to increase or decrease the current page.

However, the FLOF service of TELETEXT broadcasting is not provided in all areas. For example, it has been implemented in regions such as the United Kingdom and Spain, but has not been implemented in regions such as Germany and France. In areas where these FLOF services are not implemented, TELETEXT
In many cases, the 100-digit page, the 10-digit page, and the 1-digit page are associated with the TELETEXT information content of the large, medium, and small categories, respectively. For example, 100 pages are news programs, 110 pages are political news, 120 pages are economic news, while 200 pages are
The page stand is for sports, 210 page stands is baseball, 220
The page stand is like soccer.

[0008]

[Problems to be Solved by the Invention] In countries where FLOF service is not provided, the FLOF function using the color key (25) cannot be used, so the TELETEXT page setting is only in direct input mode. The number of digits must be entered and the operation is troublesome.

In countries where FLOF service is not provided, [RED] key (21), [GREEN] key (22), [YELLOW] key (23), [CYAN] key ( The color key (25) consisting of 24) is unnecessary. Therefore, we have to prepare two types of remote control transmitter (2) with color key (25) and remote control transmitter with no color key (25) separately for areas where FLOF service is provided and areas where FLOF service is not provided. did not become.

Ideally, it is preferable that the operation of TELETEXT is simple without a FLOF service, and that the same remote control transmitter (2) can be used regardless of the presence or absence of the FLOF service.
The present invention is easy to operate without a FLOF service,
The function of the color key (25) is automatically switched between areas where FLOF service is provided and areas where it is not provided, and the same remote control can be used in common in both areas. Television receiver with TELETEXT function (1)
Is to clarify.

[0011]

A television receiver with a TELETEXT function (1) according to the present invention comprises a detection means (6) for detecting the presence or absence of a FLOF signal in a broadcast signal in a control section (4), Detection means
Depending on the detection result of (6), [RED] key (21), [GREEN] key (2
2), the function of the color key (25) consisting of the [YELLOW] key (23) and [CYAN] key (24) is switched, and the setting means (7) for displaying the switched function on the display (19), With the execution means (8) for executing the function of the color key (25) based on the setting of the setting means (7), the color key (25) when the FLOF service is being performed.
Has a FLOF service function, and when the FLOF service is not being performed, [RED] key (21), [GREEN] key (22), [YELLO
Color keys (25) for page switching such as [W] key (23) and [CYAN] key (24) are respectively [P-1] [P + 1] [P + 10] [P + 100]
And has the page setting function of, and displays the page setting function on the display device (19).

[0012]

[Operation] Whether or not the FLOF service is included in the broadcast signal is automatically detected by the detection means (6). Upon receiving the detection result of the detection means (6), the setting means (7), when having the FLOF service, [RED] key (21), [GREEN] key (22), [Y]
Set the conventional FLOF function to each color key (25) of the [ELLOW] key (23) and [CYAN] key (24). When the FLOF service is not provided and the current received page is set to [P], the setting means (7) sets [P-1] [P + 1] [P + 10] on each color key (25).
It has the function of [P + 100] and [P-1] [P + 1] [P + 1
Display the page by the function of [0] [P + 100] on the display (19). Since [P] is the current page that was set earlier, [P-1] means to go back one page from the current page and set the page, and [P + 1] is the current page. From page 1 to next, set page, [P + 10] sets page 10 from current page, and then [P + 10]
[0] sets the next page from the current page by 100 pages.

Therefore, in the area where the FLOF service is provided, not only the conventional FLOF service functions can be used by the executing means (8), but also in the area where the FLOF service is not provided, the color key is used. Using (25) [P-
1] [P + 1] [P + 10] [P + 100] functions can be used.

[0014]

According to the present invention, in the area where the FLOF service is provided, each function of the color key (25) can be used as usual. In addition to this, in areas where FLOF service is not provided, [P-
1] [P + 1] [P + 10] [P + 100] page operation functions can be used. Therefore, as mentioned above, although the FLOF service is not provided, the classification of the information content of TELETEXT and the TELETEXT
[P-1] [P +]
With the functions of [1] [P + 10] [P + 100], it is possible to obtain functions similar to FLOF services.

In addition, since the same remote controller can be used in the area where the FLOF service is provided and the area where the FLOF service is not provided, the manufacturing cost is advantageous.
