DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for changing the update status of display contents in a program in a data broadcast using a gap between television video signals.

[0002]

2. Description of the Related Art In recent years, characters and graphic data have been broadcast using gaps between television broadcast signals (vertical blanking interval = VBI), and a receiver can receive the data and display it on a browser screen. Available data broadcasting services are beginning to spread.

[0003] Data broadcasting programs currently provided with services include news and weather. Generally, these data broadcast programs are configured by arranging independent data files such as figures and characters on a plurality of HTML format files. Immediately after reception, each material file is temporarily stored in a storage directory with a temporary name, and then converted from the temporary name to a real name for display.
The name is described in a conversion name description file broadcast for each broadcast unit. When the receiving device receives the conversion name description file, the name conversion of a plurality of data files described therein is performed.

As described above, when the receiving device receives the converted name description file, the name conversion of the data file group described therein is performed. Therefore, the data file necessary until the converted name description file is received is received. Must be received and stored in the storage directory.

However, when the data file is being broadcast, the receiving device is not operating, or the reception condition is poor, and the data file cannot be received. The file may not exist in the storage directory. In such a case, it is necessary to replace the missing data file with a dummy data file or the like and give it a real name. Otherwise, if the real name of the data file used in the program received in the past is the same as the real name of the data file used in the program of the broadcast unit received this time, when displayed on the browser, This is because only the department becomes the past content.

However, the characters and the contents of the figures replaced by the dummy data file or the like have no meaning as information. Therefore, if the number of data files having the temporary names stored is significantly different from the number of temporary names described in the conversion name description file, the broadcast unit program received this time is not displayed and the past broadcast unit program is not displayed. It is necessary to keep the program displayed.

[0007]

A program update is performed when the number of stored data files having a tentative name is relative to the number of tentative names described in the conversion name description file. Doing it is a difficult question. If the ratio is too low, there will be adverse effects such as figures and characters dropping out of place, and if this ratio is too high, the program itself will hardly be updated on a receiving device in a poor reception environment with poor radio wave conditions. Become.

Therefore, a certain ratio is defined and operated for each receiver. However, depending on the content of the program, there are some programs where it is better to display some of the latest information at the time even if figures and characters are missing here and there. It is difficult to define the same update rate in a program.

An object of the present invention is to solve the above problems.

[0010]

According to the present invention, there is provided a means for determining a program update rate for each program from a conversion name description file in which update rate information is described.

Further, there is provided means for determining whether or not to display the contents for each data file from the conversion name description file in which the file association information is described.

By providing the above means, it is possible to finely control the updating of the display contents of the program.
