Abstract

PURPOSE: To prevent misoperation and to easily change a category with a miniaturized device by selecting and allocating plural stored categories and storing the allocated categories. CONSTITUTION: A program number and a title, which are broadcasted in a prescribed broadcasting station, are divided into the plural categories and they are stored in EEPROM 29 as lists (reservation lists). When they are registered in the reservation list, a microprocessor 22 controls a station selection circuit 2, automatically receives the programs of the categories allocated to a color key and automatically stores them in RAM 23. The number (eleven) of categories, which is more than the number (four) of the color keys, are registered in the reservation list, and three programs are registered in the respective categories. Thus, the desired program can speedily be selected only by operating a category change part 62 without increasing the number of the color keys to eleven.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program selection device and method, and more particularly to a program selection device and method suitable for use in receiving teletext.

[0002]

2. Description of the Related Art At present, in Japan, teletext signals such as news and weather forecasts are broadcast by multiplexing text and graphic information on television signals.

FIG. 19 shows a configuration example of a conventional teletext receiving system. This system includes a teletext receiving device 102 and a remote controller 9 for remotely controlling the device.
It is basically composed of two.

The remote controller 92 is a numeric key 93 operated when inputting a channel number, a program number, etc., and a television mode (TV) key 9 operated when selecting a TV mode for receiving a television signal.
4 and a teletext mode key 95 that is operated when selecting a text mode for receiving teletext.

Further, the remote controller 92 is provided with category keys 96-1 to 96-6. On these category keys 96-1 to 96-6, the names of the categories "news", "sports", "traffic information", "stocks", "weather", and "others" are printed.

The category keys 96-1 to 96-5 include
Each category of "news", "sports", "traffic information", "stock", and "weather" is assigned as a default. User can select "Other" category key 9
Any category can be assigned to 6-6. Furthermore, two teletext programs can be assigned to each category.

The teletext receiving apparatus 102 has a built-in memory for storing the categories corresponding to the category keys 96-1 to 96-6, and the memory stores therein the category keys 96 as shown in FIG. 20, for example. The categories, program numbers, and program titles assigned to -1 to 96-6 are stored.

When any of the category keys 96-1 to 96-6 of the remote controller 92 is operated, an infrared signal corresponding to the category key is output from the remote controller 92 to the teletext receiver 102. When receiving the infrared signal, the teletext receiving device 102 causes the CRT 103 to display the program number and title of the category assigned to the category key. Looking at this display, the user performs an operation of designating a desired program from the two programs with the remote controller 92. When receiving the operation signal, the teletext receiver 102 receives the instructed program through the antenna 101, and the CRT 1
It is output to 03 and displayed.

[0009]

By the way, in the conventional apparatus, it is possible to assign a category other than the fixed display to the category keys 96-1 to 96-5 whose category names are fixedly displayed. It is possible. For example, the category key 96-1 in which the characters "News" are fixedly displayed is assigned a category such as "Education" that is not fixedly displayed, or the category "Sports" is assigned to another category key. Can be assigned. However, if you do so, the name of the category that is fixedly displayed (for example, "News") and the category that is actually assigned to that category key (for example, "Education") will not match, and the assignment will be performed. Other than
There was a risk of erroneous operation. In addition, even the person who has made the allocation has to remember the allocation, and the memory fades over time, so that there is a risk of erroneous operation.

Further, since the category actually assigned to the category key is stored, the operation for changing the assigned category is troublesome and time-consuming. To prevent this, for example, category keys corresponding to all categories may be provided.
In that case, there is a problem that the number of category keys increases and the remote controller becomes large.

The present invention has been made in view of the above circumstances, and is intended to prevent an erroneous operation and to easily change a category with a small device.

In addition to the above, the key 70 is operated to increase / decrease the channel or volume, the key to increase / decrease the program number of a teletext program, or the page to increase / decrease a predetermined program page. It has keys and so on.

Next, the operation will be described. The operation panel key 41 is operated to input a tuning command of a predetermined broadcasting station to the microprocessor 22 (for the same input, the remote controller 43 is operated to the microprocessor 22 via the remote control signal receiving circuit 42). Can also be supplied).

The microprocessor 22 controls the tuning circuit 2 in response to this instruction to receive the broadcasting station corresponding to the instruction. As a result, the tuning circuit 2 receives the radio wave of the broadcasting station corresponding to the command via the antenna 1, supplies the audio signal to the audio demodulation amplification circuit 3, and supplies the video signal to the luminance amplification color demodulation circuit 4. To do. The voice demodulation / amplification circuit 3 demodulates the input voice signal, further amplifies it, and then outputs it to the voice switching circuit 8. At this time, the voice switching circuit 8 is controlled by the microprocessor 22 and is switched so as to select the output of the voice demodulating and amplifying circuit 3. As a result, the output of the audio demodulation / amplification circuit 3 is supplied to the audio output circuit 9, further amplified there, and then supplied to the speaker 10 for sound emission.

On the other hand, the luminance amplification color demodulation circuit 4 amplifies the input video signal and executes color demodulation processing,
The output signal is supplied to the video switching circuit 5. The video switching circuit 5 is controlled by the microprocessor 22,
At this time, the output of the luminance amplification color demodulation circuit 4 is selected and switched so as to be supplied to the video output circuit 6. The video output circuit 6 amplifies the video signal input via the video switching circuit 5 and outputs it to the CRT 7 for display.

Next, when the operation panel key 41 or the remote controller 43 is controlled to instruct the reception of the teletext program of a predetermined broadcasting station, the microprocessor 22
The tuning circuit 2 is made to receive the radio wave of the instructed broadcasting station. The sampling circuit 21 of the teletext decoder 11 extracts teletext data contained in the video signal output by the channel selection circuit 2 and stores it in the RAM 23.

Of the teletext data stored in the RAM 23, the character code is supplied to the character generator 25, converted into a character image, and then written in the display memory 28 as a part of the display image. Further, of the teletext data stored in the RAM 23, the graphic information data is directly written in the display memory 28 as a display image.

The display image written in the display memory 28 is converted into a video signal by the display processing circuit 27 and supplied to the video switching circuit 5. Video switching circuit 5
Is controlled by the microprocessor 22 at this time to select the output of the display processing circuit 27 and output it to the video output circuit 6. The video output circuit 6 amplifies the input signal and outputs C
Supply to RT7. As a result, the teletext program is displayed on the CRT 7.

On the other hand, of the teletext data stored in the RAM 23, the additional sound data is supplied to the additional sound decoder 26 and converted into an audio signal. The voice switching circuit 8 is
At this time, the microprocessor 22 controls and switches to select the output of the additional sound decoder 26. As a result, the audio signal output from the additional sound decoder 26 is supplied from the audio switching circuit 8 to the audio output circuit 9, amplified there, and then output to the speaker 10 and emitted.

Next, referring to the flow chart of FIG.
A process for setting a teletext channel in the list shown in FIG. 2 will be described. First, in step S1, the user turns on the menu key 74 of the remote controller 43. Then, the remote controller 43
As a result, an infrared signal corresponding to the menu key 74 is output and received by the remote control signal receiving circuit 42.
The remote control signal receiving circuit 42 outputs a signal corresponding to this received signal to the microprocessor 22. When receiving a signal corresponding to the operation of the menu key 74, the microprocessor 22 executes the process of displaying the menu in step S2.

That is, the microprocessor 22 has an on-screen display (OSD) function and causes the display memory 28 to store data necessary for displaying a menu. Then, the display processing circuit 27 converts the data into a video signal, and the video switching circuit 5 and the video output circuit 6
It is output to the CRT 7 via and displayed. This allows
For example, a menu screen as shown in FIG. 5 is displayed.
On this menu screen, selection items for making various settings are displayed.

Now, the process of automatically setting the teletext channel is performed, but before that, the channel of the original television signal is made to correspond to each key of the numeral keys 1 to 12 of the remote controller 43. Perform the process to Therefore, the user performs an operation of selecting "tuner setting" from the menu screen shown in FIG. 5 in step S3. That is, when the selection keys 75U and 75D are operated, the cursor shown by the triangular figure in FIG. 5 moves up and down. Then, after moving the cursor to the "tuner setting" line, the enter key 76 is operated.

When this operation is performed, the microprocessor 22 executes an automatic TV channel setting process. That is, the microprocessor 22 uses the tuning circuit 2
Control to sequentially receive radio waves from a plurality of broadcasting stations. Then, each broadcasting station is made to correspond to the numeral keys 73 of the numbers 1 to 12 and stored in the EEPROM 29. Thus, for example, in the Tokyo area, the numbers 1, 3, 4, 6, 8, 1,
NHK TV, NHK Educational TV, Nippon TV, TBS TV, Fuji TV, TV Asahi, and TV Tokyo are corresponded to the number keys 73 of 0 and 12.

Upon completion of this automatic television channel setting process, the microprocessor 22 causes the CRT 7 to display the character "Return". In step S5, the user operates the selection keys 75U and 75D to move the cursor to that position, and operates the decision key 76 to select "return". When this selection is made, the microprocessor 22 executes the processing of displaying the menu screen shown in FIG. 5 again on the CRT 7 in step S6.

Next, in step S7, the user performs an operation of selecting "automatic character program" from the menu screen. That is, the cursor is moved to that position with the selection keys 75U and 75D, and the enter key 76 is operated. At this time, a square cursor is displayed on the character "OFF" displayed on the right side of the line where the character "Automatic character program" is displayed. When the selection keys 75U and 75D are operated in step S8, this character is changed from "OFF" to "ON".
Then, after changing to the "ON" state, the enter key 76 is operated.

At this time, the microprocessor 22 proceeds to step S9 to execute automatic character channel setting processing. The details of the processing will be described later with reference to the flowchart of FIG. 7, but this allows the broadcasting stations registered in the list shown in FIG. 2 (telemo in this embodiment).
Is scanned and its channel number is registered in the list.

During the automatic character channel setting process, the microprocessor 22 causes the CRT 7 to display a message "The automatic character program is being set". When this setting process is completed, in step S10, the text program setting screen as shown in FIG. 6 is displayed on the CRT 7
To display.

On this character program setting screen, step S9
The channel set in is displayed. In the display example of FIG. 6, it is assumed that the broadcasting station of Telemo is being broadcast on the fourth channel, and the registration state is displayed. The user looks at this display and determines in step S11 whether or not this setting is correct. If the setting is incorrect, the process proceeds to step S12, and the operation for correcting the setting is performed.

In the case of the display example of FIG. 6, the telemo is set to the fourth channel, but in the Tokyo area, the telemo is set to the first channel. Therefore, in this case, the selection keys 75U and 75D are operated to increment or decrement the channel number,
Correct to the first channel. Then, when the first channel is displayed, the enter key 76 is operated. This means that the correct settings have been made. That is, the first channel is stored in the list of FIG. 2 (this state is shown in FIG. 9.
Will be described later).

If it is determined in step S11 that the correct settings are made, or in step S12
When the correction process is completed in step S13,
Then, the user operates the menu key 72 again.
At this time, the microprocessor 22 operates in step S14.
Delete the menu displayed in.

In this way, when the reservation list stored in the EEPROM 29 is completed, the microprocessor 22 subsequently executes the programs registered in the reservation list and allocated to the color keys. When the power of the device is turned off, the data is automatically received and the RAM
23.

The teletext program is composed of one or more pages. In addition, each broadcasting station broadcasts a plurality of teletext programs, and after transmitting data for one page of a predetermined program, next transmits data for one page of another program. As a result, there is a predetermined interval between the transmission of data of a predetermined page of a predetermined program and the transmission of data of the next page of the program. According to the standard, this interval time is 20 seconds at maximum. As a result, from when the command for receiving a predetermined program is received until the data of that program can be actually received,
In the worst case, it will take 20 seconds.

However, if data is stored in the RAM 23 in advance in this way, when a command for receiving the program is input, the data stored in advance is read and displayed, so that after the reception command, The program can be displayed immediately.

Next, the details of the automatic character channel setting process (process of the automatic character channel setting unit 61) in step S9 of FIG. 4 will be described with reference to the flowchart of FIG. First, in step S31, a variable n representing the channel number selected is initialized to 1. Then, in step S32, the channel n (in this case, n
= 1) is selected. That is, the microprocessor 22 controls the tuning circuit 2 to select the first channel. Which broadcasting station the first channel represents is set by the automatic TV channel setting process in step S4 described above.

Next, in step S33, it is determined whether or not there is teletext data in the data received from the currently selected broadcasting station. If it is determined that the teletext data does not exist, the process proceeds to step S37 and the variable n
Is incremented by 1, and in step S38, it is determined whether or not the incremented variable n is equal to or larger than the maximum receivable channel number. When it is determined that the variable n is smaller than the value of the maximum receivable channel, the process returns to step S32, and the process of selecting the channel of the variable n incremented in step S37 is executed. Then, in step S33, it is determined whether or not the teletext data is present in the reception signal received at that time. If there is no teletext data, the process proceeds to step S37 again, and the variable n is incremented by 1.

As described above, the variable n is incremented by one, and when it is determined in step S38 that the variable n has reached the maximum receivable value, step S38.
Proceeding to 39, the desired teletext channel does not exist in this area, and the process is terminated without registering the channel number in the list shown in FIG.

On the other hand, if it is determined in step S33 that the received signal contains teletext data, the process proceeds to step S34 to wait until the text data is obtained from the received signal, and the text data is obtained. At this time, it is determined whether the character data of the desired channel.

That is, as shown in FIG.
)) Telemo's teletext program is stored in the list, and I am looking for the channel that is broadcasting this Telemo now, but the teletext screen of the channel that Telemo is transmitting is, For example, as shown in FIG. 8, the characters "Telemo" are displayed in the header at the top of the screen. Therefore, when the channel currently being received is a telemo channel, the character code of "telemo" should be included. Therefore, it is possible to determine whether or not the channel currently being received is the "Telemo" channel based on whether or not the character code "Telemo" is included. Also, for example, in the case of Nippon Television, the characters "AXSES4" are included in the header. Therefore, by determining whether or not a character code representing a predetermined broadcasting station is included in this header,
The broadcasting station of the channel can be identified.

Alternatively, the character multiplex broadcasting broadcast by each broadcasting station is obliged to include a broadcasting station code (transmission identification number: SID) for identifying each broadcasting station ("text broadcasting technology handbook". Broadcasting Technology Development Council). Therefore, the broadcasting station can be identified from this transmission identification number.

In step S35, if it is determined that the received signal does not include the characters "Telemo" or the transmission identification number of Telemo, the broadcasting station is the broadcasting station of Telemo. Therefore, the process proceeds to step S37, the variable n is incremented by 1, and the process of receiving the next broadcasting station is executed.

On the other hand, when it is determined that the signal received in step S35 includes the character code of "Telemo" or the transmission identification number, the process proceeds to step S36, at which time the signal is received. The registered channel numbers are registered in the list shown in FIG. As a result, for example, in the Tokyo area, this list becomes as shown in FIG. That is, the channel 1 is set corresponding to the broadcasting station “Telemo”.

The process of step S4 in FIG. 4 is performed before the process of step S9 is performed in step S9.
This is because if the automatic character channel setting process (1) is performed before the automatic TV channel setting process of step S4, incorrect setting may be performed. That is, the process of step S9 sets a character multiplex broadcasting channel, but if the original channel number of the television signal for which the character multiplex is performed is not set correctly, the character multiplex broadcasting channel setting is performed. Because there is a risk of making a mistake.

In steps S11 and S12,
It is possible to correct the teletext channel that has been set once, for example, if there is a character string containing the characters "Telemo" in the received signal, the broadcast station is erroneously detected as "Telemo". This is because there is a fear that this can be corrected.

As described above, when a list of broadcasting stations and program numbers and titles of programs broadcast by the broadcasting stations is stored in the EEPROM 29, as shown in the flowchart of FIG. It is possible to tune in by watching the programs being broadcast by the station for each category.

That is, first, in step S41, the television signal of the first channel is now received,
It is assumed that the image is displayed on the CRT 7. In this state, when the character key 77 of the remote controller 43 is operated in step S42, the microprocessor 22 selects from the reservation list for each category of the character multiplex broadcasting being performed on the channel of the television broadcasting which is being received now. , The category assigned to the color key is read from the EEPROM 29, and C is read in step S43.
Display on RT7. As shown in FIG. 10, in this embodiment, channel numbers, program numbers, and titles of three programs in each of the weather forecast, news, sports, and memory categories are displayed.

It is possible to arbitrarily set which four categories among the eleven categories shown in the reservation list of FIG. 9 are displayed (corresponding to the color key), but as described above. By default, weather, news, sports, and memory are set. Therefore, as shown in FIG. 10, they correspond to four color keys 71R, 71G, 71Y, and 71B, respectively. Corresponding colors are displayed in the names of the categories of weather forecast, news, sports, and memory.

Then, in step S44, when any one of these color keys 71R, 71G, 71Y, 71B (for example, color key 71B) is operated, it is a program of the category corresponding to the color key, and is one of three. The program (number 1) displayed at the top is selected,
In step S45, the program is displayed on the CRT 7.

That is, when the microprocessor 22 is registered in the reservation list shown in FIG. 9, the microprocessor 22 controls the channel selection circuit 2 to select the category assigned to the color key from the programs registered in the reservation list. Program is automatically received and stored in the RAM 23 automatically. Then, of the programs stored in the RAM 23, the data of the program designated by the color key is read and output to the CRT 7,
Display it.

In step S45, "previous page" and "next page" are displayed as red and green selection items, respectively. Therefore, the displayed page can be changed to the previous page or the next page by operating the red color key 71R or the green color key 71G. When the user does not perform such a page operation, the display is automatically changed to the next page when a predetermined time has elapsed.

From the display state of step S43, the second
In order to select the second or third program displayed, once the display state of step S45 is entered, the color key 71Y which is the color key of the color of the memory 2 (selects the second program. Or the color key 71B (when selecting the third program) which is the color key of the memory 3 is operated.

In step S44, the teletext program can be viewed by directly inputting the program number using the number keys 73 instead of the color keys.

Next, with reference to FIGS. 11 and 12, a process of changing the category corresponding to the color key (process of the category changing unit 62) will be described. First, in step S51, the character key 77 is operated. At this time,
In step S52, the microprocessor 22
On the CRT 7, three programs (registered as default) belonging to the categories (in this case, weather forecast, news, sports, and memories) set for each color key are displayed.

Next, the user operates the reservation key 78 in step S53. Then, in step S54, the microprocessor 22 causes the CRT 7 to display the reservation mode screen. At this time, the category corresponding to the color key is displayed on the reservation mode screen. In this embodiment, the weather forecast is displayed on the color key 71R, the news is displayed on the color key 71G, and the color key 71R is displayed.
It can be seen that sports is registered in Y and memory is registered in the color key 71B as corresponding categories.

Next, the user selects the category to be changed,
Select by operating the color key of the corresponding color. For example, if the "news" category to which the green color key 71G corresponds is changed to the "life / living" category, the green color key 71G is changed to step S.
Operate with 55.

At this time, the microprocessor 22 displays the programs belonging to the "news" category selected in step S55 in step S56. And
As selection information at the top of this screen, the category, cursor, decision, and return selection items are displayed in red,
Display with green, yellow, and blue colors added.

Since the process for changing the category is being performed, the user operates the red color key 71R corresponding to the category selection item in step S57. At this time, the microprocessor 2
In step S58, 2 displays other categories that are not associated with the color keys and also displays a red cursor in a predetermined category (traffic information in the case of the embodiment).

In this state, when the user operates the red color key 71R in step S59, the red cursor moves in response to the operation. The user operates until the red cursor moves to the display position of "lifestyle" which is the category to be changed. At this time, in step S60, the microprocessor 22 displays a red cursor on the characters "life".

Next, in step S61, the user selects the yellow color key 71Y corresponding to the selected selection item.
To input the decision command. At this time, the microprocessor 22 reads out the program information of the category "life / living" from the reservation list shown in FIG.
At CRT7.

Next, when the blue color key 71B corresponding to the "return" selection item is operated in step S63, the microprocessor 22 is operated in step S64.
Changes the category displayed corresponding to the green color key 71G up to then from "news" to "life / living". Therefore, after that, the green color key 71G
You can select the category of "life / living" by operating.

When such a category change is made, EE
The reservation list of the PROM 29 is as shown in FIG.
That is, as is clear from comparing FIG. 13 and FIG. 9, the flag G corresponding to the color key 71G is changed from “news” to “life / living”.

As described above, the program is automatically registered (reserved) for each category by executing the processing shown in the flowcharts of FIGS. 4 and 7. However, the program can be reserved by manual operation. It is also possible to register in the list. The operation in this case will be described with reference to the flowcharts of FIGS. 14 and 15.

First, in step S71, a state in which a program on a television channel which is broadcasting a character broadcast desired to be reserved is being watched is set. Next, in step S72, the index key 72 is operated. At this time, the microprocessor 22 causes the CRT 7 to display the table of contents mode menu in step S73. In this state, when the user selects the red selection item "display table of contents" in step S74, the microprocessor 2 is selected in step S75.
2 causes the CRT 7 to display a table of contents screen. That is, the microprocessor 22 receives the table of contents of the teletext program that is being broadcast by being multiplexed with the television signal received in step S71, and displays it on the CRT 7.

At this time, as a selection item for selecting the displayed program number, the program number to which a color is added is displayed above the screen. If the user wants to reserve the teletext program with the program number 999 #, for example, in step S76, the user operates the red color key 71R corresponding to the program number. When the color key 71R is operated, the microprocessor 22 reads the data of the operated program number from the RAM 23 and displays it on the CRT 7 in step S77. In this state, the user operates the reservation key 78 in step S78. Then, the microprocessor 22
In step S79, the CRT 7 displays the reservation mode screen.

On this reservation mode screen, the categories corresponding to the respective color keys at that time are displayed. In this case, the weather forecast, news, sports, and memory categories are displayed with corresponding colors (red, green, yellow, and blue) added.

Then, in step S80, the user operates the color key corresponding to the category to which the program specified in step S76 is desired to be assigned (corresponding to). For example, if you want to assign the 999 # teletext program to a memory category, use the blue color key 7
Operate 1B.

When the blue color key 71B is operated,
In step S81, the microprocessor 22
At that time, three programs registered in the "memory" category are displayed, and at the same time, step S77,
The program reserved in S78 is displayed.

In this state, in step S82,
When the yellow color key 71Y corresponding to "OK" is operated, the process proceeds to step S83 and the microprocessor 22
Newly registers the top three programs displayed in step S81 in the "memory" category. Therefore,
Until then, the program that was registered as the third program will be unregistered.

When the designated program is reserved in this way, the process proceeds to step S84, and the reserved screen is erased by operating the blue color key 71B to which the "return" selection item is assigned.

FIG. 16 shows a reservation list when a program is reserved manually in this way. This Figure 1
As is clear from comparison of FIG. 6 with FIG. 13, a program called “stray cock” of the program number 999 # of the sixth channel is newly registered at the head of the category of “memory”, and the program that has been registered until then is registered. "The Go" of program number 715 # of channel 1 has been deleted from the reservation list.

Incidentally, in the above-mentioned embodiment, FIG. 2, FIG. 9, FIG.
3. As shown in FIG. 16, there is one reservation list,
It may be two lists as shown in FIGS. 17 and 18. In the list of FIG. 17, 11 categories and 3 programs each corresponding thereto are registered. FIG.
The color key and the category assigned to it are registered in the list.

FIG. 18A shows the default allocation. The list of FIG. 18A is shown in FIG. 11 and FIG.
By performing the processing shown in the flowchart of FIG.
Change as shown in (B) (green color key 71G
The category corresponding to will be changed from "news" to "life / living").

As described above, in the reservation list, the number of categories (4) or more (11) is registered, and three programs are registered in each category. . Then, four of the eleven categories are made to correspond to the color keys. As a result, a desired program can be quickly selected only by performing a relatively simple operation (category changing operation) without increasing the number of color keys to 11. In addition, it is possible to prevent the apparatus main body and the remote controller 43 from increasing in size.

In the above, one broadcasting station (telemo)
Although only the reservation list of No. 1 is stored in the EEPROM 29 in advance, it is needless to say that the reservation lists of a plurality of broadcasting stations may be registered in advance.

Also, the number of color keys and the number of categories are
If the latter is set to be larger than the former, other values can be set.

The present invention has been described above by taking the case where the character information is broadcast by superimposing it on the television signal.
The present invention can be applied even when receiving information other than character information.
