Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program reservation system for facsimile broadcasting, and more particularly to a program reservation system that can display a list of programs for facsimile broadcasting on a monitor device.

[Prior Art] Currently, facsimile broadcasting is being studied for practical use, and various manufacturers are now at the stage where they are prototyping facsimile broadcast receivers.

Here, facsimile broadcasting is a method that uses television broadcast radio waves to sequentially transmit fixed image information such as text, graphics, photographs, etc. using scanning technology, and reproduces an image as close to the original as possible on the receiving side. The main output method considered is a hard copy method.

Therefore, in addition to the broadcasting characteristics of simultaneous broadcasting and instant reporting, it also has the recording and archiving properties of print media. Because of these characteristics of recordability and storage, there is little need for real-time reception, and it is thought that presetting programs and selective reservation reception will become more common.

Therefore, it is necessary for the facsimile broadcast receiver to have a program reservation function. By the way, as a program reservation method for such a facsimile broadcast receiver, it is possible to apply a reservation method for existing television receivers and teletext receivers.

That is, the user may make a reservation by operating various keys while referring to a facsimile broadcast program list listed in a newspaper, magazine, or the like.

[Question B to be solved by the invention] By the way, the so-called A4 size is selected as the standard document size for facsimile broadcasting, and the so-called 6
The resolution has been selected to be sufficient to recognize the characters in the number print, and in addition to the image signal from this A4 size document, various control signals such as network signals, program selection signals, color section designation signals, etc. is added to form a facsimile signal for one page, and a time of 2 minutes and 30 seconds is allocated to the facsimile signal for one page.

Therefore, the total number of pages that one broadcast network can broadcast in one day is 576 pages, and even if one program is composed of several pages each, the number of programs will be extremely large. Furthermore, the number of broadcasting networks is expected to increase as facsimile broadcasting is considered to be used as a complement to television broadcasting or teletext broadcasting, and as a result, the number of facsimile broadcast programs per day will be enormous. .

Therefore, even if you find a desired facsimile broadcast program from a list of facsimile broadcast programs written on paper and manually operate the keys, just like television broadcasts or teletext broadcasts, it is necessary to keep your eyes on the line between the program guide and the key operation section. Since the programs change frequently, there is a strong possibility that the day of the week, broadcast slot number (corresponding to the broadcast time), channel number, etc. of the program may be mistakenly recognized, which can easily lead to reservation operation errors. Also, Shinkai,
In magazines and the like, there is also the problem that a large amount of space is taken up by the program guide for facsimile broadcasts.

The present invention has been made in consideration of the above points (therefore, it is an object of the present invention to provide a program reservation system for facsimile broadcasting that can reserve programs for facsimile broadcasting by simple operations without using a paper program list. That is.

[Means for Solving the Problem] In order to solve the problem, the present invention provides a teletext receiver that extracts a teletext signal from a broadcast radio signal;
A monitor device that displays a teletext signal obtained by the teletext receiver, a facsimile broadcast receiver that extracts a facsimile signal from a broadcast radio signal, and a printer device that prints out the facsimile signal obtained by the facsimile broadcast receiver. In a composite reception system comprising: a mode selection key for setting a facsimile broadcast program reservation mode when receiving and displaying a teletext program consisting of a facsimile broadcast program list; and a cursor superimposed on the display image of the monitor device. The operation input means of the teletext receiver is provided with a cursor movement key for moving the cursor and a registration key for importing the facsimile broadcast program to be reserved. and a facsimile broadcast program reservation section that operates the facsimile broadcast receiver only during the reception time, and the control means in the teletext receiver operates the facsimile broadcast program reservation section that operates the facsimile broadcast program only during the reception time. Display the cursor over one of the facsimile broadcast programs, change the facsimile broadcast program indicated by the cursor according to the press of the cursor movement key, and change the facsimile broadcast program indicated by the cursor when the registration key is pressed. Information about the program is transferred to the broadcast program reservation department by facsimile as reserved program information.

[Operation] The present invention attempts to reserve a facsimile broadcast program using a list of facsimile broadcast programs that are broadcast as one of teletext programs.

In other words, when a mode selection key is pressed while receiving and displaying a teletext program, the teletext receiver displays a cursor superimposed on one facsimile program on the displayed image, and when a cursor movement key is pressed, Accordingly, a cursor is moved over the facsimile broadcast program displayed on a monitor device, and when a registration key is pressed, information about the facsimile broadcast program indicated by the cursor at that time is given to a facsimile broadcast program reservation section as reserved program information.

Then, when the facsimile broadcast program reservation section reaches the time of the facsimile broadcast program indicated by the reserved program information,
The facsimile broadcast receiver is operated and the facsimile broadcast program is printed out by the printer device.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a combined reception system for television broadcasting, teletext broadcasting, and facsimile broadcasting, in which a receiving antenna 1 receives broadcast waves.

This received signal is given to a channel selection demodulator 2 and a facsimile broadcast receiver 3.

The channel selection demodulator 2 extracts the signal of the designated channel from the received signal, demodulates the signal, and provides the obtained composite video signal to the teletext receiver 4.

The teletext receiver 4 has a central processing unit (CPU) 4a.
, a memory 4b, a display memory 4C, etc., and a key bat 5.
When the receiving mode instructed by , or the receiving mode instructed by the operation panel of the teletext receiver 4 is the television broadcasting mode, the composite video signal is directly given to the monitor device 6 for display.

On the other hand, if the instructed reception mode is the teletext mode, the teletext receiver 4 extracts the code data inserted in a predetermined horizontal scanning period in the vertical blanking period of the composite video signal, and The data is converted into data and stored in a built-in display memory 4c, and a video signal based on teletext is obtained and provided to the monitor device 6 for display.

The facsimile broadcast receiver 3 first transmits a received signal received by the receiving antenna 1 to the facsimile receiver 3.
Select the channel specified by the operation panel,
The signal obtained by tuning is FM demodulated to extract the FM modulated signal and voice signal of the facsimile signal, and then the FM modulated signal of the facsimile signal is discriminated, and the FM modulated signal of this facsimile signal is FM demodulated to generate the facsimile. A signal is obtained and given to the printer device 7 to print out the signal.

In addition to the above reception and output configuration, this composite reception system has a program reservation configuration for facsimile broadcasting.

On the keypad 5, there are provided a mode selection key 5a, an up key 5b, and a down key 5c for selecting the facsimile broadcast program reservation mode. When the mode selection key 5a is pressed, the CPLI4a
is configured to execute a facsimile program reservation program shown in FIG. 2 stored in the memory 4b.

Second, because facsimile broadcasting is also used as a supplement to teletext broadcasting, and because the network station for teletext broadcasting and the network station for facsimile broadcasting are often the same station, facsimile broadcasting is It has been decided that the transmitting station will transmit a facsimile broadcast program list as one of the teletext programs. In this embodiment, as will be described later, data regarding the facsimile broadcast program to be reserved is extracted from the program list of facsimile broadcasts as teletext programs.

By executing the above-mentioned program, the retrieved reserved program data is given to the facsimile broadcasting group reservation section 8, which has a microcomputer configuration consisting of a CPU 8a and a memory 8b. Since the reserved program data given to the reservation section 8 follows the data format for teletext as described above, the reservation section 8 decodes the reserved program from the data and stores the information of the reserved program. The reservation unit 8 also includes a timer 8c, and when the current time measured by the timer 8c reaches the start time of the reserved program, the facsimile broadcast receiver 3 is activated, and when the end time comes, the facsimile broadcast receiver 3 is stopped.

When a user makes a reservation for a facsimile broadcast program using the above configuration, after operating the teletext receiver 4 and displaying the teletext program in the receiving state on the monitor device 6,
Press the mode selection key 5a. At this time, the CPU 4 a of the teletext receiver 4 starts the facsimile program reservation program shown in FIG. 2, and determines in step SPI whether the teletext program being received is a program in the list of facsimile broadcast programs. . If a negative result is obtained, the program reservation program is immediately terminated.

On the other hand, if the teletext program being displayed is a facsimile broadcast program list, the cursor CUR is placed at the initial position on the broadcast time frame of the displayed facsimile broadcast program list TAB as shown in Figure 3. to be displayed superimposed.

Here, since the display format of the facsimile broadcast program list is predetermined, the CPU 4 a moves the cursor to C.
The UR can be displayed over the broadcast time slot. In addition,
Broadcast time frames are divided into 2 minutes and 30 seconds each day, which is the transmission time of one page, and the frame number from 12:00 a.m. to 12:02:30 is ``1'', hereinafter 2 minutes and 30 seconds. The frame number is incremented by 1 for each broadcast, and corresponds to the broadcast time.

When the cursor CUR is displayed in this way, the user presses the up key 5b or down key 5c on the keypad 5 to change the position of the cursor CUR, and when the cursor position reaches the desired facsimile broadcast program, All you have to do is press the mode selection key 5a again.

After displaying the cursor CUR at the initial position as described above, the CPU 4a then determines whether or not the mode selection key 5a has been pressed in step SP3, and if it has not been pressed, the up key 5b is pressed in step SP4. Determine whether or not the button has been pressed. Up key 5b
If the cursor CUR is pressed, it is determined in step SP5 whether or not the currently displayed cursor CUR is in the top broadcast frame, and if it is in the top broadcast frame, the display image is changed in step SP6. Scroll down to move the cursor CUR to the previous broadcast frame and proceed to step SP8. If it is not the top broadcast frame, proceed to step S.
At P7, move the cursor CUR to the previous broadcast frame without scrolling down, and proceed to step SP8.
Proceed to. Incidentally, even if the up key 5b is not pressed in step SP4 described above, the process proceeds to step SP8.

In this step SP8, it is determined whether or not the down key 5c has been pressed, and if it has not been pressed, the process immediately returns to step SP3 described above. On the other hand, if the down key 5c is pressed, it is determined in step SP9 whether the current display position of the cursor CUR is at the position of the lowest broadcasting frame, and if an affirmative result is obtained, step 5 PIO Scroll the display image up and display the cursor CUR in the broadcast frame immediately after that. When Ikegata obtains a negative result, move the cursor CUR to the broadcast frame immediately after that without scrolling up in step 5P11. Move and display.

By repeating the loop process consisting of steps SP3 to SP5PII, the user's up key 5b and down key 5b
In response to pressing c, the cursor CUR moves over the broadcast frame,
Eventually, a cursor CUR is displayed in the broadcast frame for the facsimile broadcast program desired by the user.

At this stage, since the user presses the mode selection key 5a again, an affirmative result is obtained in step SP3, and the process proceeds to step 5P12. In this step 5P12,
The CPU 4a transfers the pattern data for the broadcast frame in which the cursor CUR is displayed to the facsimile broadcast program reservation unit 8 along with pattern data such as the channel number, month and day, and day of the week displayed in the header section HEA on the image. Then, terminate the program.

At this time, the built-in C
The PU 8a obtains the channel (network), month, day, and day of the week from the transferred pattern data, and also obtains the broadcast start time and end time from the broadcast frame and stores them in the memory 8b.

After this, in the same way as the conventional timer reservation operation, the timer 8c monitors whether the current time has reached the start time of the reserved facsimile broadcast program, and when the program start time arrives, the facsimile broadcast receiver 3 is activated. After starting, the facsimile broadcasting receiver 3 monitors whether the current time has reached the end time or not, and stops the operation of the facsimile broadcast receiver 3 when the end time of the program has come.

Therefore, according to the above-described embodiment, it is possible to reserve a facsimile broadcast program by a simple key operation while visually viewing the list of facsimile broadcast programs as teletext programs displayed on the monitor device 6, which improves operability and improves operability. Usability can be further improved.

In the above-described embodiment, the data transferred from the teletext receiver 4 to the facsimile broadcast program reservation unit 8 is pattern data, but it may also be code data.

Furthermore, reservations for facsimile broadcast programs can be made not only by using teletext programs as described above, but also by key operations on the operation panel of the facsimile broadcast receiver 3, as in the past. Also good.

Further, in the above embodiment, mode selection -5a is used as a key for registering a reserved program, but it may be provided separately.

[Effects of the Invention] As described above, according to the present invention, a facsimile broadcast program can be reserved by a simple key operation while a program list of facsimile broadcast, which is one of the teletext programs, is displayed on the monitor device. It is possible to obtain a program reservation system for facsimile broadcasting with good operability and ease of use.
