Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a teletext receiver which simplifies the teletext reception operation.

[0002]

2. Description of the Related Art As digital information services whose technical environment has been improved, there is currently only teletext broadcasting, and teletext is attracting attention as one of the approaches to the coming multimedia. However, in the current teletext receivers, the program selection is not simplified, and a technique for simplifying the program selection is necessary for further popularization.

FIG. 7 shows a program selection method in the existing teletext receiver. First, select the teletext and search for the program you want to watch from the set channels. If there is no target program, the channel is changed, the program to be watched is searched from among the changed channels, and this operation is repeated until the target program is found.

When the program is found, the program can be viewed by inputting the 3-digit program number and the # key. Therefore, it is necessary to enter the key at least five times to view the program.

[0005]

As described above, in the conventional teletext receiving apparatus, in order to watch a program, it is necessary to key in at least 5 times even if it is a program that is often watched. There is a problem that you cannot see immediately.

[0006]

In order to solve the above problems, the present invention reserves a plurality of teletext programs (eg, weather forecast, news, sports news, stocks, etc.) that are often viewed in advance as the first invention. Then, a plurality of patterns corresponding to the program are prepared in advance. Each picture has information about a channel and a program number, and the contents of each program can be visually understood (hereinafter, a picture having such a function is referred to as an icon).

[0007] When actually watching a program,
(EN) Provided is a teletext receiving device which first displays an icon on a television screen and then can display necessary information by three operation key inputs for selecting / determining the icon.

As a second invention, an aspect ratio of 1
In a 6: 9 television, the video is horizontally compressed by a horizontal compression circuit, the horizontally compressed video is displayed at the left end or the center of the TV screen, and a plurality of icons are displayed in the non-video part to perform the same method as the first invention. (EN) Provided is a teletext receiving device capable of selecting a program.

As a third aspect of the invention, a program selection according to the first or second aspect of the invention is performed by adding the icon confirmation frequency to the information of the above icons and displaying the icons on a television screen in order of frequency. (EN) Provided is a teletext receiving device whose operation is simplified.

[0010]

According to the present invention, a plurality of teletext programs often viewed in advance (for example, weather forecast, news, sports news, stocks, etc.) can be viewed with three operation key inputs by the above-mentioned device. Furthermore, on a 16: 9 aspect ratio TV screen, the video part is horizontally compressed and displayed at the left end or center,
By displaying a plurality of icons in the non-video part, it is possible to effectively use the screen having the aspect ratio of 16: 9 and eliminate the loss of video. Further, by introducing the program confirmation frequency, it is possible to further improve the operability.
