Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television character multiplex broadcasting system, and more particularly, it replaces display screen data or note data of a page having program information with another display screen data or note data to obtain a new program content. Regarding the method of sending.

[0002]

2. Description of the Related Art In a conventional television character multiplex broadcasting system, display screen data or note data of a specific page in program information already created is replaced with display screen data or note data created separately. In this case, the sending device side does not perform these processes, but the terminal side that creates the display screen performs the process, and the new display screen created here is re-registered in the sending device.

[0003]

PROBLEM TO BE SOLVED BY THE INVENTION In many cases, program information is distributed online between communication stations of a series through a communication line, and is simultaneously transmitted on air to different broadcast stations. In addition to the information pages such as news and weather forecasts provided to the recipient, the page may also include a commercial message page (hereinafter referred to as CM) page transmitted on air by the broadcasting station of the distribution source.

However, in the above-mentioned conventional television character multiplex broadcasting transmission system, a broadcasting station which receives distribution and transmits on-air has the following drawbacks because it replaces the CM page of its own station and transmits on-air. .. That is, after receiving the distribution of the program information, it is necessary to delete the CM page of the other station and insert the CM page of the own station by the operator's operation on the display screen creating apparatus to create the new program information, which has a high responsiveness. Absent.

[0005]

The television character multiplex broadcasting system of the present invention comprises display screen data or note data in which page-by-page display screen information or melody information provided to a receiver is digitized and expressed. The information of a program whose page is composed of a single page or multiple pages is superimposed on an arbitrary horizontal scanning period of the vertical blanking retrace line of the television video signal, and a plurality of programs different from television broadcasting are sequentially time-divided. In the television character multiplex broadcasting transmission system, which is configured to be sent out, and which is provided with a program number which is program identification information at the top of the page of the information of the program, and which is configured to be sent out individually or repeatedly. With knitting data that determines the sending order and processing for the stored display screen data or note data,
The specified page display screen data or note data of the program information is replaced with the separately created display screen data or note data according to the instruction of the composition data.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 2 (a) shows the internal format of program data that is normally transmitted. In normal program transmission, one program is transmitted based on the order of internal page management information. In program A of FIG. 2A, page management information P10 is used.
, The event data is sent in the order of P20, P30, ..., PNO.

FIG. 2B shows program data created separately for replacement, and these are also stored in the same format as normal program data. In this example, program B and program C are page management information. This indicates that the page has a two-page configuration of P10 and P20. The page structure may be a single page structure or a multiple page structure. See also FIG.
The contents of the image for one page shown in (a) and (b) may be displayed screen data only, display screen data and note data, or only note data.

Here, an example is shown in which the P20 and PNO pages of program A are replaced with the P10 page of program B and the P20 page of program C.

FIG. 1A shows the format of the knitting data for instructing this replacement. Is program A at 10:00
It is shown that the air is sent from 0 minutes 00 seconds to 24:00:00 seconds. Is P20 of program A and P of program B
Replacing with 10 means replacing the PNO page of program A with the P20 page of program C.

The sending device, based on the instruction of this organization data immediately before the on-air sending, broadcasts the program A based on the order of the page management information in the program P10, P20, P3 in FIG. 2 (a).
0, ... Trying to send pages in the order of PNO,
P20 of program A
The page 0 is replaced and the PNO of program A is replaced with P20 of program C by the same instruction. FIG. 1B shows the order of each page finally sent on air as a result of this replacement.

These processes are instructed by the organization data that has been input in advance, and it is possible to freely replace the pages of various programs by changing the instruction content of this organization data. Generally, it is used to replace the CM page of the own station with the program distributed from the distributor including the CM page.
It can be used for various operations such as program titles.

[0013]

As described above, according to the present invention, the processing for replacing the display screen data or the note data of the specified page of the program information with the display screen data or the note data stored in advance in the transmission device in the television character multiplex broadcasting. Is automatically performed according to the organization data that has been input in advance, so that it is possible for only the sending department to instruct replacement of the own CM and the like, and it is possible to respond promptly.
