DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television teletext system, and more particularly to a system for generating and transmitting page header information of each page of a program.

[0002]

2. Description of the Related Art In transmitting a page header of conventional teletext broadcasting, page header information to be transmitted is created in advance on each page in a terminal which creates a screen together with page text information. Sent this without any processing.

[0003] In many cases, the page header information displays a program title, a broadcast station name, a serial page number, or information on the date of transmission.

[0004]

In this conventional television teletext system, programs are exchanged between stations, a program is carried in from a production agency, and a commercial message (hereinafter referred to as a CM) for the first, middle and last pages of the program. ) Because of the necessity of renumbering consecutive page numbers by inserting pages, rewriting page header information on the terminal that creates the screen,
Alternatively, additional work has to be performed.

[0005]

According to the television teletext broadcasting system of the present invention, page header information and page body information, which are display screen information in page units, provided to a receiver are converted into display screen data that is represented by digitization. The transmission processing of the program information is defined in a television character multiplex broadcasting system in which a page constituted by a single page or a multi-page configuration is superimposed as program information in an arbitrary horizontal scanning period of vertical erasure retrace of a television video signal. The knitting data and at least the data of the page text information among the display screen data are stored in advance in a sending device, and the knitting data includes generation information of the page header information. The page header information is automatically generated and added to each of them.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 2 shows a configuration of a display screen of one page of a program transmitted by television teletext broadcasting.
H is page header information, and generally displays a broadcast station name, a program title, a page number, date information, and the like in many cases. F is page body information, in which information to be provided to the recipient, such as news and weather forecast, is displayed.

As shown in FIG. 3, the transmission of the program is performed by forming the page display screen of FIG. 1 into a plurality of pages and further adding a CM page. 1 to n indicate page numbers, H1 to Hn are page header information of each page, and F1 to Fn are page body information of each page. In this example, the first page is a CM page, and pages 2 to n are information pages provided to the recipient such as news and weather forecast.

[0009] These page display screens are created by a terminal that creates the screen, but the CM page is created by an advertising agency.
Generally, an information page is created separately by an information provider, and there are cases where page header information is created and cases where it is not created.

[0010] Regarding this page header information, it is necessary to change the broadcast station name depending on the broadcasting station that sends out the information even if the page header information is carried in from the same information provider. is there. For this reason, it is necessary to rewrite the broadcast station name, the number of continuous pages, the date information, and the like. Conventionally, before broadcasting, the page header information is changed or newly added at the terminal that creates the screen. I was working.

FIG. 1 shows the structure of the organization data that determines the program transmission process. The composition data includes information such as a time zone a for transmitting the program, a CM addition designation b, and the like. An instruction sign c for adding page header information to this data and a program title character string d can be designated. .

In this embodiment, the sending apparatus recognizes the sign indicating the addition of the page header information of the organization data, and if the sign is added, whether the page header information is already included in the display screen information of each page. It determines whether or not the page header information is included, and deletes the page header information. The program title character string specified in the organization data, the date information and station name information held by the transmitting device,
New page header information is generated based on the page number obtained by counting the number of pages sequentially from the first page including the CM page added by the transmission device, and the page header information is added again.

When the page header information is not included in the display screen information, the transmitting apparatus adds the newly generated page header information as described above.

[0014]

As described above, according to the present invention, the page header information is automatically generated and added to each page of the program based on the instruction of the organization data which preliminarily stores the program transmission processing stored in the transmission apparatus. Accordingly, there is no need to rewrite or add page header information in a terminal for creating a screen, which has been conventionally performed, and an effect of providing a text multiplex broadcasting system with high immediate information can be provided.
