Abstract

PURPOSE:To easily and simply call the contact of a page picture with designation without selecting a picture desired based on a page number of providing a control section comparing a page content inputted by an operating section and a page content list. CONSTITUTION:A control section 3 compares a page contact designated by a operating section 6 with a broadcast page content to control extracting a picture of the designated page content. That is, a page as a list comprising page numbers and page contents is read among a picture generated by a data analysis section 2 by means of a data storage section 4 and the control section 3 compares the contents of data inputted from the operating section 6 to select the page number of the read page content. Thus, since a page picture desired is selected by designating the content of the page, desired picture is immediately designated among many pages of pictures.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a teletext receiving device that is effective for use in televisions, video tape recorders, and the like.

Conventional teletext receiving devices are used as receiving devices for various types of information such as news, airline seat reservation information, and weather forecasts, and the fields of use are about to increase.

Hereinafter, an example of the teletext receiving apparatus described above will be described with reference to the drawings.

FIG. 3 shows a schematic block configuration of a conventional teletext receiver. In the figure, reference numeral 1 denotes a teletext data extraction unit that extracts teletext data from a video signal containing the teletext signal. Reference numeral 2 denotes a data analysis section that creates a screen based on the data extracted by the teletext data extraction section. 6 specifies the page number of the screen to be selected on the operation unit using three digits. For example, if you want to select 120 pages, use the operation unit to input three digits in sequence: "1", "2", and "O". Reference numeral 3 denotes a control section which issues commands to the data analysis section 2 on the three-digit data inputted from the operation section. Reference numeral 4 denotes a data storage unit that stores screen data created by the data analysis unit 2. Reference numeral 5 denotes a data conversion section that converts data read from the data storage section into a video signal.

Problems to be Solved by the Invention However, with the above configuration, it is difficult to check whether the content on the screen of the page number specified by the operation panel is the content that you wanted to select by monitoring the screen of the page number that you actually selected. The only way to judge is to visually check the page number, and if it's incorrect, you'll have to enter the page number again, and you're not sure if the screen with that page number is the one you want to see.

In view of the above-mentioned problems, the present invention provides a teletext receiving device that allows users to specify the content of the screen they want to see instead of specifying the page number, and allows them to quickly select the screen they want to see. .

Means for Solving the Problems In order to solve the problem described in item 1, the teletext receiving device of the present invention displays a list of page numbers and contents of the pages among the screens created by the data analysis section. The control section is equipped with a comparison section that reads out a page from the data storage section, compares the contents of data input from the operation section in the control section, and selects the page number of the specified page contents.

Effects of the Invention With the above configuration, the present invention allows a user to select a page screen that he or she wants to view by specifying the contents of that page, so that a user can immediately specify a screen that he or she wants to view from among a large number of page screens.

Embodiment Hereinafter, a teletext receiver according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of the invention. In FIG. 1, ■ is a teletext data extraction unit that extracts teletext data from a video signal sent from a broadcasting station. Reference numeral 2 denotes a data analysis section that creates a screen from the teletext data extracted by the teletext data extraction section. Reference numeral 4 denotes a data storage unit that stores the screen data created in step 2 above. FIG. 2 is an example of the screen that has been created, showing the page number and the list surface showing the contents of that page. FIG. 16 shows an operation section through which input is made to select a desired screen.

FIG. 5 shows a data input method using a bar code, which is one of the data input means.

FIG. 4 shows an example of a bar code indicating the contents of the screen to be selected. A desired page screen is designated by reading this barcode with a barcode reader and transmitting the data to the control section 3. This page screen selection method may be any other method as long as it specifies the contents of the page.

The control unit 3 compares the page content specified by the operation unit 6 with the page content being broadcast, and performs control to display the screen of the specified page content. Reference numeral 5 denotes a data conversion section which takes out the page screen data selected by the control section 3 from the data storage section 4 and converts the page screen data into a video signal.

The operation of the teletext receiving apparatus of this embodiment configured as described above will be described below with reference to FIGS. 1 and 2. First, the control unit 3 compares the page content to be selected inputted from the operation unit 6 with the page content list as shown in FIG. It is possible to automatically determine the page number of the content and call up the page with the specified content.

As described above, according to this embodiment, by providing a control unit that compares the page content input from the operation unit 6 with the page content list as shown in FIG. You can easily and easily call up the page by specifying the contents of the page screen instead of selecting by number.

Effects of the Invention As described above, according to the present invention, information in a teletext broadcast is not selected by a page number whose page content is unknown (
By specifying the "content" that you need, you can obtain excellent effects such as being able to call up the necessary screen more quickly (and more accurately and easily).
