The parts corresponding to those in FIG. Are omitted as appropriate. As shown in FIG. 1, in this embodiment, the microprocessor 22 substantially has a program number analysis section 61 and a program number display control section 62 which are configured by a program. The program number analysis unit 61
Data corresponding to the program number is identified from the teletext data stored in the AM 23, and a process of listing it is executed. The program number display control unit 62 executes processing for developing the listed program numbers in the display memory 28 as a display image and displaying the developed program number on the CRT 7. Other configurations are similar to those shown in FIG.

Next, the operation will be described. The operation when viewing a normal television broadcast is the same as in FIG. That is, the microprocessor 2
2 controls the tuning circuit 2 in response to a command from the operation panel key 41 or the remote controller 43 to receive the radio wave of a predetermined broadcasting station. The audio signal is demodulated and amplified by the audio demodulation / amplification circuit 3, and then output from the speaker 10 via the audio switching circuit 8 and the audio output circuit 9. The video signal is amplified and demodulated in the luminance amplification color demodulation circuit 4, and then output and displayed on the CRT 7 via the video switching circuit 5 and the video output circuit 6.

On the other hand, when the operation panel key 41 or the remote controller 43 is operated to instruct the display of the table of contents screen of the teletext program, the microprocessor 22 controls the channel selection circuit 2 to make a broadcast corresponding to the instruction. Receiving station radio waves. Then, the sampling circuit 21 is made to extract the teletext data and stored in the RAM 23. Further, the microprocessor 61 extracts the data of the table of contents screen from the teletext data stored in the RAM 23. Then, of the teletext data of the table of contents screen, the character code is supplied to the character generator 25, converted into a character image, and stored in the display memory 28. The graphic information in the teletext data is expanded and stored in the display memory 28 as it is. Regarding the additional sound data of the teletext data,
The audio signal is converted by the additional sound decoder 26, and the sound is emitted from the speaker 10 via the sound switching circuit 8 and the sound output circuit 9.

Further, the program number analysis unit 61 of the microprocessor 22 identifies the program numbers among the characters expanded in the display memory 28, lists them, and stores them in the RAM.
23.

That is, the program number represented by character data is represented by a code defined by the 8-unit code for information exchange of JIS C6228-1984 used in, for example, a computer for data communication.
For example, the program number 123 is "2" in the 2-byte code.
It is represented by 1,31 "," 21,32 "," 21,33 ", and in a 1-byte code," 31 "," 32 "," 3 "
3 ". The code itself is also represented regardless of the character size and display position. The program number analysis unit 61 identifies this code and creates a three-character program number string.
A process of converting to a digit number and rearranging in ascending order (sorting process) is executed.

In this way, the RAM 23 stores a program number list as shown in FIG. 2, for example. In this embodiment, program numbers 001, 110, 111 and
22, 400, 441, 442 and 443 are arranged in order of the magnitude of the value.

When displaying these program numbers, the program number display control unit 62 displays colors for each program number in order to prevent the program numbers from being difficult to see due to overlapping with the character graphic display image. In the case of this embodiment, the background color) is set. In the embodiment of FIG. 2,
For each program number, in order from the top, red, green, yellow, blue,
Each color of red, green, yellow, and blue is set as the background color.

The program number display control unit 62 further causes the character generator 25 to convert the character code into a program number (numerical) image so that the program numbers listed in this list are displayed in the set background color. , And stores it in the display memory 28. At this time, the background color data is stored in the display memory 28 so that the background color shown in FIG. 2 is displayed on those characters. Further, at this time, the program number display control unit 62 controls so that each program number is regularly displayed. For example, all program numbers are characters of the same size, and their display positions are controlled so that they are displayed horizontally or vertically in the order of values.

The display image thus expanded and stored in the display memory 28 is converted into a video signal by the display processing circuit 27 and is output and displayed on the CRT 7 via the video switching circuit 5 and the video output circuit 6. As a result, a table of contents screen as shown in FIG. 3, for example, is displayed.

As is clear from the comparison of the display example shown in FIG. 3 with the conventional display example shown in FIG. 12, the original program number (the program number displayed together with the # symbol) is displayed on the table of contents screen. Is displayed as it is (that is, displayed without regularity). However, in the present embodiment, in addition to that, all the program numbers displayed on the screen are collectively displayed in a predetermined position horizontally and vertically with characters of the same size. The program numbers are displayed in different background colors in ascending order of program numbers (in sorted order).

That is, in the display example of FIG. 3, 00
The program numbers 1,110,111,222 are red, green, yellow, and blue background colors, respectively, and have the same size. Horizontally, a small program number is located on the left side and a larger program number is on the right side. The numbers are displayed as they are located. Also,
The program numbers of 400, 441, 442, and 443 are displayed vertically, with the red, green, yellow, and blue background colors, respectively, so that the small program numbers are on the top and the large program numbers are on the bottom. Has been done.

Therefore, the user can quickly and surely recognize the program number displayed on the index screen.

FIG. 4 shows another display example. In the display example of FIG. 3, the added program number is arranged inside the teletext screen image 52, but in the embodiment of FIG. 4, the teletext screen image 5 is displayed.
2 outside. This makes it easier to distinguish the added program number from the program number originally displayed.

In the display examples of FIGS. 3 and 4, the program numbers are displayed in different colors (background colors). For example, as shown in FIGS. 5 and 6, the background of each program number is hatched. It is possible to display by applying (FIG. 5) or by applying hatching (FIG. 6).

Various modifications are conceivable, such as changing the display position of the program number, the shape and color of the background, and changing the regularity of the arrangement of the program numbers.

As described above, in this embodiment, the additional program number is displayed in addition to the original program number, but it is also possible to additionally display the program name. is there. Further, the display position may be displayed in a direction other than the horizontal direction or the vertical direction. In short, it suffices to display them with regularity.

Next, an application example of such display will be described. FIG. 7 shows a configuration example of the remote controller 43. As shown in the figure, the remote controller 43 has a key 70 that is operated when inputting various commands.
have. Among these keys 70, there are color keys 71
It includes R, R1G, 71Y, 71B, a table of contents key 72, and a numeric key 73.

The color key 71R is printed in red, the color key 71G is printed in green, and the color key 71Y is printed in yellow. The upper part of the color key 71B is printed in blue.

For example, when the table of contents key 72 is turned on, the microprocessor 22 reads the data corresponding to the screen in the table of contents mode from the ROM 24 and stores it in the display memory 28. Then, this data is read and output to the CRT 7 via the display processing circuit 27, the video switching circuit 5, and the video output circuit 6 for display. As a result, for example, a screen in the table of contents mode as shown in FIG. 8 is displayed.

[Table of contents display] is displayed on the screen of this table of contents mode.
The key graphic with the characters and the corresponding message "You can select the program from the table of contents" is displayed. Also,
If you know the figure of the key that contains the characters "program number" and the corresponding "program number, press this key.
You can directly select the program "message is displayed. Then, a red color is added to the "table of contents display" key, and a green color is added to the "program number" key.

The user sees this display and "displays the table of contents"
When selecting, the red color key 71R is operated, and when selecting "program number", the green color key 71G is operated. When the microprocessor 22 is supplied with the input signal corresponding to this color key, the CRT 7
The process is performed assuming that the key corresponding to the color displayed in is selected. Therefore, when the operation signal of the red color key 71R is received, it is assumed that the "display table of contents" key has been selected, and the CRT 7 displays the table of contents screen as shown in FIG. When the operation signal of the green color key 71G is received, it is assumed that the "program number" key has been selected, and the CRT 7 displays the table of contents screen as shown in FIG.

As described above, when the color keys are independently made to correspond to each screen corresponding to various selection information, the number of keys prepared in advance in the remote controller 43 (or the operation panel key 41) is reduced, Miniaturization is possible. Further, it is not necessary to select one key from many keys, and the operability is improved.

In the table of contents screen shown in FIG. 9, titles of programs (in the embodiment of FIG. 9, the program number 703 and the program number 808) and the brief introduction are displayed. Then, above it, the characters 703 # (program number) with a red background and the characters 808 # (program number) with a green background are displayed. Therefore, in this case as well, by operating the red color key 71R or the green color key 71G instead of inputting the key 703 # or 808 # with the numeric keys 73, the program number 703 # or 80
8 # programs can be selected.

On the other hand, when the program number input screen is displayed as shown in FIG. 10, the number keys 73 of the keys 70 are operated to directly input the program number and select the program. . Using the color keys reduces the number of key operations,
Operability is improved.

In order to enable selection by operating the color keys from the display state shown in FIG. 3 or 4, the display of the same color in one screen is made one (that is, the display in the vertical direction or the horizontal direction). Erase one).

Although red, green, yellow, and blue are used in the above description, this is merely an example, and it goes without saying that other colors can be used. Also, the number may be 5 or more, or 3 or less.

[0056]

As described above, according to the display control device of the first aspect and the display control method of the eighth aspect, the display-related data in the received signal is converted into the display data, and the display-related data is displayed. A predetermined data is identified, data corresponding to the identified display is generated, display data according to a common rule is generated separately from the conversion process, the display data obtained by the conversion, and the display data obtained by the generation. Since the display data is combined, it is possible to quickly and surely select the desired display.

Further, in the information selecting device and the information selecting method according to claim 10, the selection information for selecting the received information is displayed with a predetermined color added, and the added color is displayed.
