This is extremely troublesome for viewers, and there are inconveniences in which they may be lost.

(4) Means for Solving the Problems The present invention has been made in view of the above points, and allows text programs to be broadcast without preparing a correspondence table between the contents of text programs such as news and weather forecasts and item numbers. In order to achieve this purpose, key inputs operated by the viewer are used in a teletext receiving device that receives teletext programs transmitted as teletext and outputs them as images. A memory circuit that registers combinations of magazine numbers, program numbers, and page numbers output from the device with index characters representing the content of character programs in correspondence with item numbers, and a memory circuit that displays item numbers to issue selection instructions. and a selection instruction means for selectively instructing to output a text program when a text program corresponding to the magazine number, program number, and page number stored in the memory circuit is received, and the item number is displayed. It is configured to display an index character in addition to the item number when making a selection instruction.

(5) Effect With this configuration, in addition to the magazine number, program number, and page number, index characters representing the contents of the text program can be registered in advance in the memory circuit and displayed, so that the user can read the text program while looking at the index characters. Acts to make choices.

(6) Examples Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a teletext receiving apparatus according to the present invention. Further, FIGS. 2 and 3 are flowcharts explaining the operation of the circuit shown in FIG. 1.

The operation of the teletext receiving apparatus according to the present invention is divided into an "index registration operation" shown in FIG. 2 and an "index access operation" shown in FIG. 3. The two operations are C
This is realized by processing performed by the PU circuit 1 based on a program stored in the program ROM 5. Therefore, these two operations will be explained using a flow chart of the program stored in the program ROM 5. First, the "registration operation" shown in FIG. 2 will be explained with reference to FIG. 1, and then the "registration operation" shown in FIG. The "index access operation" shown in FIG. 1 will be explained with reference to FIG.

The "index registration operation" starts when the "index registration operation" is selected by operating the key input device 2, as shown in FIG. When the ``index registration operation'' is selected, it is first determined whether the ``success'' key or the ``centaf'' key of the key input device 2 has been pressed. When the "Succeed" key is pressed, the mode is entered to create a matching list of item numbers, magazine numbers, program numbers, page numbers and indexes, which will be explained later.
When the "Centaf" key is pressed, a mode is entered in which it is selected whether or not to function the "index access operation", as will be explained later.

When the "Success" key is pressed, it is then determined which of the item numbers was pressed using the cursor key of the key input device 2. When an item number is selected using the cursor key of the key input device 2, the system waits for manual input of the magazine number, program number, and page number.

The magazine number and program number are predetermined five-digit numbers and symbols for programs such as news and weather forecasts, and the page numbers are numbers and symbols that are predetermined for programs such as news and weather forecasts. This is the number that specifies the page when Note that when the page number is "00", all pages are specified.

If the number keys "θ~9" or the "1" (asterisk) key or "l" key are pressed while waiting for manual input of the magazine number, program number, or page number, the program will be displayed at the item number. After setting the number, select the next “O~9”
The program returns to the state of waiting for the numeric key "" or the "1" key or the rlJ key, and ends manual input of the magazine number, program number, and page number.

Next, press the "N" key to enter manual index mode. In the mode for manually inputting the index, a character table as shown below is displayed on the display, and characters can be manually input by selecting from this character table using the cursor keys of the key input device 2. The character table may be a table of kana characters in addition to the alphabets exemplified here.
For example, in the case of an index for a stock market program number, the input characters can be characters that are easy for the viewer to understand, such as "turnip".

Character table → ↑↓ #()! ”#$%＆゛0本十、+、101234567 89; : <=>? @ABC DEFGHIJKLMNO PQR5TUVWXYZ r ¥J-'abcdefg hijklmnopqrs tuvwxyz (l) Index manpower To finish, select "mode" on key input device 2, It is detected by selecting either "↓" in the character table or "#" in the character table. "Mort", "
When either "↓" or "#" is selected, the mode returns to the mode in which the magazine number, program number, page number, and index are entered manually for the next item number.

The completion of manually inputting the magazine number, program number, page number, and index to the required item number is detected by pressing the "Mote" key while waiting for the manual input of the magazine number, program number, and page number. Ru. "mode"
When a key press is detected, a combination list of magazine number, program number, page number, and index is written into the nonvolatile memory 3. This non-volatile memory 3
``Index registration operation'' is completed by writing the magazine number, program number, page number, and index combination list to . At this point, a list of combinations of item numbers, magazine numbers, program numbers, page numbers, and indexes has been stored in the nonvolatile memory 3 as shown in the following table, for example.

1: 01000 OO books Soumokuji 2: 0100
1*OO books News 3: 01010 books OO books Tenkiyohou 4: 01020 wood OO books On-cuff 52O 1030 books 00 books Spawn 6: 01040 books OO books Cub 7: 01050*00 books Shinseihin 8: 01
060 * 00 Thursday Shinbun Nai When the above-mentioned "index registration operation" is selected and it is determined whether the "Success" key or the "Centaf" key is pressed, if the "Centaf" key is pressed, As will be explained next, a mode is entered in which it is selected whether or not to function the "index access operation".

When the ``Centaf'' key is pressed, the operator waits for either ``Yes'' or ``No'' to be selected using the cursor key of the key input device 2 for confirmation.

When "Yes" is selected, a flag indicating that "index access operation" is to be started is set.
At the same time as writing to the nonvolatile memory 3, an "index access operation" to be described next is started. When "No" is selected, a flag indicating that the "index access operation" is to be canceled is set (reset) and written to the non-volatile memory 3, and the "index registration operation" is ended.

Next, "index access operation" will be explained.

The "index access operation" starts when "index access operation" is selected by operating the key input device 2, as shown in FIG.

When "Index Access Operation" is selected, it is first determined whether or not the currently displayed screen is scrolling, and since access is not possible when the screen is scrolling, "Index Access Operation" is terminated. .

When the screen is not scrolling, the screen created by the above-mentioned "index registration operation" is displayed. In the previous example, the screen displayed at this time is as follows.

1: Soumokuji 2: News 3: Tenkiyohou 4: Ongaku 5: Sports 6: Turnip 7: Shinsei Hin 8: Shinbu Annai In this state, wait until the item number is selected using the cursor keys and then the "#" key is pressed. When the "#" key is pressed after an item number is selected, it is determined whether a program number is registered in the selected item number.

If the program number is not registered, delete the screen display created in the "index registration operation" performed earlier, and then
End "index access operation". If the program number has been registered, select the program number, erase the screen display created in the previous "index registration operation", and end the "index access operation". In addition, after selecting the item number using the cursor keys,
By pressing the "mode" key, the "index access operation" can be forcibly terminated.
