Description

Description: TECHNICAL FIELD The present invention provides a facsimile channel provided with a second carrier wave in an audio frequency band of a television broadcast wave, and receives a broadcast facsimile in which a facsimile signal is multiplexed with an audio signal and transmitted. The present invention relates to a broadcast facsimile receiving apparatus.

(Prior Art) In recent years, various studies have been made with the aim of commercializing a broadcast facsimile using the second carrier as described above. Some of the provisional specifications are shown in FIG. 3 and FIG. FIG. 3 is a configuration diagram of a facsimile signal for one print output screen, and FIG. 4 shows an audio frequency band in which the facsimile signal is multiplexed.

First, the configuration of the facsimile signal will be described with reference to FIG.

Data transmission for one print output screen takes 150 seconds, and is synchronized between the broadcasting stations.

Among the control signals, the network signal 1 is a signal for transmitting operation data between broadcast stations. The program selection signal 2 is a signal for transmitting control information on program selection on the receiver side. The color section designation signal 3 is a signal for designating a color section in the image within the page to the receiver. The page or program end signal 6 is a signal indicating the end of the image signal of one print output screen to the receiver. The blank signal 7 is a signal to be inserted into the receiver in order to secure operation time such as cutting of the recording paper after printing.

The phase signal 4 is a reference signal for adjusting the recording start phase of the receiver. The image signal 5 is an analog signal for printing out a gradation. The no signal 8 is an adjustment period for adjusting the transmission time of one print output screen to 150 seconds.

Next, an audio frequency band in which a facsimile signal is multiplexed will be described with reference to FIG. That is, the transmission of the facsimile signal is performed in a voice frequency band of 94.5 kHz (6.
× f _H, f _H: doing the transmission of facsimile signals data channel is newly provided according to a second carrier of the horizontal synchronizing pulse frequency) (facsimile signal subcarrier).

In a broadcast facsimile receiving apparatus based on such specifications, a plurality of program numbers (page numbers if necessary) and channel numbers desired to be printed out are input in the receiving apparatus in advance. When receiving the broadcast wave, the program number (page number if necessary) in the program selection signal 2 of each channel while switching the demodulation channel of the receiver.
Is compared with a program number and a channel number which are input and set in advance in order to print out, and when they match, the image signal 5 is printed out.

However, in such a broadcast facsimile receiving apparatus, even if reserved program information (such as a program number and a channel number) desired to be printed out is input and set, when the power of the receiving apparatus is turned off, the data of the input set program is lost. There is a problem of disappearing.

Also, even if reserved program information for which print output is desired is set in a certain receiving device, if the user wants to print out the data in another receiving device, the program data is input to the receiving device again by key operation. There is an annoyance that it has to be done again.

In a broadcast facsimile, a very large number of programs, up to 576 programs per day, are transmitted per channel.
Furthermore, as in the case of teletext, the program numbers are sorted by genre, and programs with the same program number indicate the contents of the same genre, and the contents of the same program number may be updated as needed. Under such circumstances, it is expected that the above-mentioned problem of frequently inputting and setting the reserved program information will be closed-up.

(Object of the Invention) The present invention has been made in view of such circumstances, and can save reserved program information input and set to a broadcast facsimile receiving apparatus, and can save the saved reserved program information. It is an object of the present invention to provide a broadcast facsimile receiving apparatus which can easily input and set other receiving apparatuses.

(Structure of the Invention) In order to achieve such an object, the present invention has the following structure.

That is, a broadcast facsimile receiving apparatus according to the present invention comprises: program information input means for inputting reserved program information relating to a program to be printed and output; program information storage means for storing the inputted reserved program information; Program information extracting means for extracting information (current program information) relating to a currently transmitted program from a facsimile signal obtained by receiving and demodulating the program information; reserved program information input by the program information input means; A program information comparing unit that compares the current program information extracted by the extracting unit, and prints an image signal obtained by demodulating the facsimile broadcast wave when the reserved program information matches the current program information. A broadcast facsimile receiving apparatus comprising: a print output unit for outputting the program information; With the reservation card for exchanging program information, the reservation card with detachably mounted to the apparatus main body, is characterized by having a nonvolatile storage medium which stores the reserved program information.

 Next, the operation of the present invention will be described.

The reserved program information input from the program information input means is stored in the program information storage means. A broadcast facsimile receiving apparatus in which the reserved program information is stored in the program information storage means,
When the reservation card is inserted, the reservation program information stored in the program information storage means is written to a recording medium in the reservation card. Since this storage medium is non-volatile, it is stored as it is even if the power of the broadcast facsimile receiver is turned off.

On the other hand, when the reservation card on which the reserved program information is written is inserted into the broadcast facsimile receiver, the reserved program information written on the reservation card is transferred to the program information storage means of the broadcast facsimile receiver.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The display unit 12 includes a display unit 12 for displaying channel numbers and program numbers (or receiving program numbers) and a recording unit 13 for printing and outputting facsimile signals.

Reference numeral 14 denotes a key input unit as program information input means. The key input unit 14 is, for example, a receiving device main body via a cable 15.
Connected to 10. By operating a key on the key input unit 14, reserved program information such as a reserved channel and a reserved program number is input.
It is taken into the receiving apparatus main body 10 via 15. Of course, transmission of the reserved program information can also be performed without using the cable 15, for example, by optical transmission or ultrasonic transmission.
Alternatively, the reserved program information may be input using a light pen, a bar code, or the like, instead of the key input.

Reference numeral 16 denotes a reservation card on which the reserved program information can be written. The reservation card 16 is removably mounted, for example, in a reservation card insertion hole 17 provided in the receiving device main body 10.
By attaching the reservation card 16 to the receiving device main body 10, the reservation program information set in the receiving device main body 10 is saved, or the input setting of the reserved program information previously written in the reservation card 16 is performed. . Such a reservation card 16 will be described later in detail.

Next, the configuration of the embodiment will be specifically described based on FIG.

The receiving apparatus main unit 10 includes a reserved program storage memory 18 as a program information storage unit, a tuner unit 19, a facsimile broadcast signal demodulation unit 20, and an image signal as a program information extraction unit in order to process the received television broadcast signal. It includes a control signal separating unit 21 and a control signal decoding unit 22, a comparing unit 23 as a program information comparing unit, a switch unit 24 which constitutes a printing output unit together with the recording unit 13, and the like. Most of the components of the receiving device main body 10 are a CPU (central processing unit),
Although it can be composed of M (read-only memory), RAM (write-readable memory), IC, individual components, etc., the receiver main body 10 is represented by functional blocks in FIG.

The reserved program information such as the reserved channel and the reserved program number input from the key input unit 14 is written in the reserved program storage memory 18 and displayed on the display unit 12.

On the other hand, the television broadcast signal a in which the facsimile signal is multiplexed is taken in from the antenna 11 and
Given to 19. The tuner unit 19, based on the channel setting signal b given from the reserved program storage memory 18,
A signal c of a desired channel is selected from the television broadcast signal a. The signal c whose channel is selected is supplied to the facsimile broadcast signal demodulation unit 20. The facsimile broadcast signal demodulation unit 20 demodulates the signal c into a baseband facsimile signal d. This facsimile signal d is
It is provided to the control signal separation unit 21. The image signal / control signal separation unit 21 separates the image signal and the control signal constituting the facsimile signal d as shown in FIG.

The control signal e separated by the image signal / control signal separation unit 21 is provided to the control signal decoding unit 22. The control signal decoding unit 22 decodes the control signal e after performing error correction and error detection of the control signal e. The program selection signal f as the current program information decoded by the control signal decoding unit 22 (reference numeral 2 in FIG. 3)
Are supplied as one input of the comparison unit 23. As the other input of the comparison unit 23, a reserved program storage memory
From 18, a reserved program number g as preset program information is given. The comparing unit 23 compares the program selection signal f with the reserved program signal g, and when they match, sets the switching signal i output to the switch unit 24 to a predetermined level, and sets the switch unit 24 to Turn on. Then, the image signal j separated by the image signal / control signal separation unit 21 is provided to the recording unit 13 via the switch unit 24. The recording unit 13 performs printing corresponding to the image signal j on recording paper.

On the other hand, if the program selection signal f and the reserved program number g do not match, the comparison unit 23 turns off the switch unit 24 to prohibit the printout by the recording unit 13 and stores it in the reserved program storage memory 18. On the other hand, another channel setting signal b is output to the tuner unit 19. Then, the same processing signal as described above is applied to the signal c of the channel selected by the newly output channel setting signal b to determine whether or not to print out.

Such an operation is performed until a program to be printed out is found, or until the search is completed for all the channels previously set in the reserved program storage memory 18. The above-described program number selection / comparison operation is performed during the transmission period (13.6 seconds) of the program selection signal 2 shown in FIG. The signal processing after the color period designation signal 3 shown in FIG. 3 is performed only when the switch unit 24 shown in FIG. 1 is turned on.

 Next, the reservation card 16 will be described.

The reservation card 16 is a rewritable nonvolatile storage medium, for example, an EEPROM (electrically erasable and programmable).
mmable read only memory). Key input section 1
The reserved program information input and set to the reserved program storage memory 18 from 4 is obtained by attaching the reservation card 16 to the receiving device body 10,
The information is stored in the reservation card 16 by a predetermined operation (for example, a key operation or an insertion operation of the reservation card 16). Since the storage medium provided in the reservation card 16 is non-volatile, even after the power of the receiving device main body 10 is turned off and the contents of the reservation program storage memory 18 are erased, the reservation program information stored in the reservation card 16 is not changed. Saved as is. Therefore,
By turning on the power of the receiving apparatus main body 10 again and mounting the reservation card 16, the reserved program information previously input and set can be restored.

When a program reserved by one receiving device is to be printed out by another receiving device, for example, the reservation card 16 storing the reserved program is attached to the other receiving device, so that the program can be transferred to another receiving device. Scheduled programs can be set immediately.

Note that, in the above-described embodiment, the EEPROM is
In addition, by providing a simple MPU (microprocessing unit), the reservation card 16 alone can set the program number and channel to be printed out. With this configuration, in a place different from the receiving device,
At any time, you can set up a reservation when you notice or when you are introduced to something, then the reservation card
This is very convenient because the reservation program information can be registered by attaching 16 to the receiving device body.

(Effects of the Invention) As is clear from the above description, according to the broadcast facsimile receiving apparatus of the present invention, a reservation card provided with a rewritable nonvolatile recording medium for reserved program information is mounted on the broadcast facsimile receiving apparatus. This makes it possible to save the reserved program information written in the program information storage means in the broadcast facsimile receiver, so that even if the power of the broadcast facsimile receiver is turned off, there is no need to input the reserved program information again, which is very convenient. It is.

Also, if a reservation card in which the reserved program information is written is prepared, the reservation card can be attached to an arbitrary broadcast facsimile receiving apparatus, so that the program can be reserved immediately. The complexity of inputting and setting program information by key operation can be avoided.
