Abstract

PROBLEM TO BE SOLVED: To facilitate operation and to improve convenience in a short time without requiring concentration so much by displaying the receiving state display menu of a page related to a selected program before displaying the page. SOLUTION: When the program of 'sports' at a channel '2' is selected out of a main menu program 101 by operating an operating part, for example, sub-menus 201-203 are displayed. Next, when the program of 'professional baseball' at the channel '2' is selected out of the sub-menu program 201 by the similar operation, a receiving state display menu 301 of the page related to the program of 'professional baseball' as the selected program is displayed. Then, when any desired page is selected out of this display menu 301 by the similar operation, the selected page among pages 401-402 is displayed. Thus, a user watches the display menu 301 to instantaneously judge the constitution of the selected program, the receiving state of the page and the discrimination whether it has already been read or not read yet, etc.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FM multiplex receiver.

[0002]

2. Description of the Related Art At the time of program broadcasting of a general FM broadcasting station, character information signals of a program (complementary program) related to the program contents and a program (independent program) not related to the program contents are used by using a gap between FM broadcasting waves. F to multiplex and transmit
FM multiplex receivers that receive M multiplex broadcasts and display the character information on a display unit such as a liquid crystal display have been put into practical use (for example, see Japanese Patent Application Laid-Open No. 8-79206).

The structure of the program in FM multiplex broadcasting is as follows:
It has a tree structure, and the specific contents of each program indicated by the submenu are described as character information below the upper hierarchical program such as the main menu program and the submenu program classified by type in this main menu program. A plurality of pages to be displayed are continued. Each page is composed of a header sentence and a main body, and the main body is 15 characters and displays a total of 30 characters of two lines at one time, and there is a next page in the same program. In this case, the screen is scrolled to display the next page.

[0004]

In such FM multiplex broadcasting, even if the user turns on the power switch, all character information (all pages) of all programs can be immediately confirmed by display. Not something you can do. The reason is that the character information signal changes in real time in accordance with the FM broadcast signal and a new character information signal is sent from one to the next, so that turning on the power switch does not always coincide with receiving the first page. On the contrary, in most cases, the program is received from the middle of the program, and it takes time to complete the reception of all pages.

Therefore, the user selects a desired program (for example, "sports") in the main menu program, moves to a submenu program, and selects a desired program (for example, "professional baseball") in the submenu program. Even if it is displayed and visually recognized, it is possible to see only the page for which reception has been completed, instead of seeing all the pages related to the “professional baseball” program. The user does not know the page information such as the number of pages in total, or the position of the currently displayed page. Incidentally, the main menu program and the sub-menu program are configured such that the main menu program and the sub-menu program cannot be displayed unless all pages related to the main menu program and the sub-menu program are received, so that the above-described problem does not occur.

Accordingly, when the user selects the "professional baseball" program, the user scrolls the screen of the display unit every predetermined time and checks again from the beginning in order to check whether all pages have been viewed. It had to be displayed and confirmed, requiring time-consuming and troublesome work. Moreover, since confirmation of the page relies on the memory of the user, there is a problem that the memory becomes ambiguous after a long period of time, so that high concentration is required.

According to the present invention, the operation of checking the reception state and viewing state of an FM multiplex broadcast page on a display screen and selecting necessary information from various received character information is easy and in a short time. Further, it is an object of the present invention to provide an FM multiplex receiver which does not require much concentration and is easy to use.

[0008]

SUMMARY OF THE INVENTION The present invention relates to an FM multiplex receiver which receives an FM multiplex broadcast for multiplexing and transmitting a text information signal by using a gap between FM broadcast waves and displays the text information. Before displaying the page related to the program selected by the program, a reception status display menu of the page related to the selected program is displayed.

Further, the present invention is characterized in that the number of read pages is displayed with a special decoration in the reception status display menu.

[0010] The present invention is characterized in that a digest sentence for estimating the content of the page is added beside the number of pages in the reception status display menu.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS By displaying page reception status display menus 301 to 303 relating to a selected program before displaying pages 401 to 420, the reception status of a page can be confirmed. The operation up to selection of the required information from the character information is easy and short, and does not require much concentration.

Further, reception status display menus 301 to 30
In step 3, by displaying the number of read pages with a special decoration, the visual recognition state of the page can be confirmed on the display screen, and until the necessary information is selected from the various received character information. The operation is easy and quick, and does not require much concentration.

The reception status display menus 301 to 30
In 3, by adding a digest sentence for estimating the contents of the page beside the number of pages, the contents of the page can be easily envisioned, and until the necessary information is selected from the received various character information. The operation is easy and quick, and does not require much concentration.
