DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a teletext receiving apparatus, and more particularly to a teletext receiving apparatus for displaying a teletext program viewed in the past in the form of an icon for each genre.

[0002]

2. Description of the Related Art Teletext is a system for repeatedly transmitting a plurality of types of program data in the form of digital signals during a specific horizontal scanning period in a vertical blanking period of a television signal.

On the receiving side, all teletext program data is extracted from the transmitted television signal and temporarily stored in a buffer memory. Then, when the user designates desired program data from the plurality of stored program data, the designated program data is read from the buffer memory and written into the presentation program memory. The program data stored in the program memory for presentation is
The display data is divided into display data and additional sound data. The display data is displayed on a screen by a presentation process using an image memory, and the additional sound data is output as sound.

[0004] By the way, in the teletext, many programs are transmitted to one broadcasting station. However, the transmitted program is, for example, a table of contents program (000 #) or a subtitle program (9
Since the program number is not specified except for 99 #), in order for the user to view the teletext using the teletext receiving apparatus, that is, to obtain desired information, for example, the following operation procedure is required.

[0005] The user first selects a channel (broadcasting station).
Then, the user selects and presents a table of contents program, searches for a desired program from the screen, and confirms the program number of the program. Thereafter, the user selects and selects the program number by key input, and executes the program number to view a program having desired information. As described above, when a user watches a teletext broadcast, the above-described complicated operation is required to obtain desired information.

Further, in the above operation, when a program number is selected and executed, selected program data (which is generally composed of a plurality of pages) is selected from all the programs stored in the buffer memory. ) Is stored in the presentation program memory and presented, but in order to check the contents of all pages of the program, it is necessary to perform a page-turn operation for all pages after selecting a desired program, which is a complicated operation. It takes time.

Conventionally, a text broadcast receiving apparatus is provided with a program memory for reservation, and a plurality of icons (characters and pictures) registered in advance in the memory are associated with program numbers of frequently-viewed text broadcast programs in advance. Register, for example,
A program has been automatically reselected by selecting and executing the icon, and a method of easily viewing a program desired by the user without requiring complicated operation and time has been devised.

[0008] By the way, when making a reservation registration setting of the teletext program in association with a plurality of icons registered in advance in the reservation program memory, the user sets an icon suitable for the contents of the teletext program to be registered. It is necessary to select from a plurality of icons registered in the program memory for reservation.

[0009] However, this operation was unexpectedly troublesome for those who are not used to it. That is, each of the plurality of icons that have already been provided (provided) is viewed mainly by design, and based on what genre the icon represents and what genre is recalled from the icon. Icon must be defined. However, some icons (pictures) are limited to a relatively narrow genre, while others include almost all genres, and even the same icon is recalled (associative) by some people. May be different. For this reason, the definition is ambiguous, and for example, a problem may occur in which, for example, the user wants to know the stock price and selects an icon, but completely different information (program) is selected.

[0010] In addition, the icon is defined for each teletext program that is frequently viewed, and the reservation registration setting for setting a program number of the teletext program for a predetermined icon is performed.
It had to be done by the user himself and was cumbersome.

[0011]

As described above, in the conventional teletext receiving apparatus, the user has to perform the definition of the icon according to the genre of the teletext program for each program, which is troublesome. The definition is likely to be ambiguous, so that when the icon is selected, a problem may occur that information (program) completely different from the one intended by the user is selected. Also,
There was a problem (defect) that the user had to make a reservation registration setting for each program on the basis of the definition of the icon and the program number of the teletext program, which was troublesome.

Therefore, the present invention has been made in view of such a problem,
It is an object of the present invention to provide a teletext receiving apparatus that does not require a user to define an icon and perform a reservation registration setting operation for a teletext program number in the icon.

Performs an icon classification operation simultaneously with the above operation.

FIG. 4 is a flowchart showing an example of the procedure of the icon classification operation of the microcomputer 3. Microcomputer 3
First, a program (hereinafter, designated program) corresponding to the program number designated by the user (input) is converted in real time from the teletext data supplied from the data extracting means 2.
Alternatively, the data is read out from the program data (text broadcast data) stored in the buffer memory 9 and decoded by the decoder 10 to add, for example, one or more predetermined pages to the header data (header data) of the designated program. May be read (step S1).

Next, the reference keywords (see FIG. 2) stored in the memory 7 are read out in a predetermined order, and the header data and the reference keywords are compared with each other (steps S2 to S6). It is determined which icon number belongs to (is classified). For example, when data (characters) such as “weather”, “temperature”, “weather”, and “precipitation” exist in the header data, the designated program is classified into icon number 1 (weather forecast) (step). S7). Similarly, in the header data,
If there is data (characters) such as "horse racing", the designated program is classified into the icon number 4 (horse racing information) (step S8). If all the reference keyword data (characters) read from the memory 7 does not exist in the header data, the designated program is classified into, for example, an icon number 99 (others) (step S9).

When the classification of the designated program is completed, the microcomputer 3 sets the memory 8 (based on the result of the discrimination (classification), that is, in correspondence with the icon number (classified) assigned to the designated program. The designated program number is stored in the program number column (see FIG. 3) (step S10).

As described above, the microcomputer 3 automatically performs icon classification appropriate to the received text multiplex broadcast program content.

Now, as described above, FIG. 3 (memory 8)
When a program number is stored in the program number column of the microcomputer 3, that is, when an icon number is assigned to the designated program, the microcomputer 3
Reads, for example, icon data (bitmap data) corresponding to the icon number from the memory 8 and sends it to the display control means 4. Then, the display control means 4 outputs the display output signal (video signal) 12 to a television receiver (not shown) via the output terminal 5, for example, as shown in FIG.
On an RT screen or a liquid crystal screen (hereinafter simply referred to as a screen) 11,
The icon 13 (icon data) is displayed at a predetermined position such as the black belt portion 12 which is not in the way and is easy for the user to identify. FIG. 5 is a diagram showing a display example of icons.

When the user selects the displayed icon using, for example, the remote controller 14 or the keyboard 6 provided in the teletext receiving apparatus, the icon selection signal 13 (icon data) is generated. The character is multiplexed by the program number stored in the memory 8 corresponding to the icon (icon number). A broadcast program is selected by the teletext receiving device and displayed on the screen 11 of the television receiver (not shown).

There are various selection methods for selecting and displaying a text multiplex broadcast program corresponding to the selected icon 13 by selecting the icon 13. For example, by limiting the program number stored in the memory 8 to one corresponding to the selected icon 13, the most recently viewed by the user as a text multiplex broadcast program selected by the operation of selecting the icon 13. How to select a program. When there are a plurality of program numbers stored in the memory 8, a method of selecting only the program most recently viewed by the user by selecting the icon 13,
A method of selecting the most recent one by selecting once in the O method and selecting the next most recent one (the same hereinafter) by selecting twice. Then, by simultaneously storing the number of times of selection for each program number stored in the memory 8, a program with a high access frequency is selected from the plurality of program numbers. Furthermore, the icons are given a hierarchy. For example, icons such as "stock" and "finance" are provided below the "economic" icon. An icon is displayed, and a method of selecting these, that is, a method of selecting a program by selecting the icon several times can be considered.

[0031]

As described above, according to the present invention, a text multiplex broadcast program can be automatically assigned (classified) to an icon suitable for the program content (genre). And define
This eliminates the need to perform the assignment operation, thereby preventing the occurrence of a problem that, when the icon is selected, information (program) completely different from the one intended by the user is selected.

Further, it is possible to more easily select a desired program from the teletext programs selected in the past.
