About.

  In a conventional television signal receiving apparatus, program related information such as a program name of a broadcast program, a program start time, and an end time is not transmitted together with a video or audio signal, and such information is displayed on a TV screen. It was impossible. Therefore, the viewer has obtained this information from the program guide described in newspapers and the like.

  Also, instead of conventional analog television signals, digital broadcasting is being started in which digitized signals are transmitted to homes by satellite, cable, and terrestrial broadcasting. Some satellite broadcasts in the United States have already been broadcast in this form, and preparations are underway for the launch of similar services in Japan. In digital broadcasting, various additional information can be transmitted simultaneously with digitized video and audio signals. By using these additional information, a program guide representing the broadcast schedule of the program can be constructed.

  On the other hand, even in the conventional analog broadcasting, by adopting a method of multiplexing the program related information during the vertical blanking interval, it is possible to configure a program table similar to the digital broadcasting. However, the amount of information that can be multiplexed during the vertical blanking period of analog broadcasting is less than the amount of information transmitted by digital broadcasting, and the information that can be handled as the screen display capability of the analog broadcast screen display function. The amount is constrained. Therefore, the display screen realized by analog broadcasting is inferior in expressiveness compared to the screen display realized by digital broadcasting.

  When displaying program-related information such as a program guide in a predetermined display area, such as on a TV screen, the display area required to display all display data is limited by the display area. When the display area is exceeded, the entire display data cannot be displayed. For this reason, there exists a fault that some information is missing among the information which can be originally shown.

  Therefore, in the present invention, the entire display data is displayed for the specific information selected by the viewer, and if the display data is missing, the display data is limited by adding a display to supplement the information. It is intended to express in the display area.
