Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to a facsimile receiving apparatus that receives facsimile signals transmitted using, for example, a communication satellite and prints based on the facsimile signals.

[Prior Art] In a communication system that transmits video and audio signals using communication satellites, if the video and audio signals are scrambled and then communicated, the receiving system that includes scramble key information and a descrambling device can be used. Only to communication destinations that have
It becomes possible to transmit video signals and audio signals normally. In such a communication system, information can be simultaneously transmitted from one transmitting side to a plurality of n communication destinations.

FIG. 9 shows the configuration of such a communication system. In the figure, 100 is a transmitting system, 200 is a communication satellite, and 300 is a receiving system.

Scrambler 101 configuring transmission system 100
is supplied with a video fl signal Sv and an audio signal SA,
Based on the control signal Sc, each signal is scrambled and, for example, the scrambling key is changed to control communication destinations that can be normally transmitted.

Here, the audio signals S and A are converted into PCM. and,
An example for a PCM audio signal! ! Pseudo-random signal (
Scrambling is performed using the PN signal). In addition,
The video signal is scrambled using, for example, an intra-scanning line signal switching method (line rotation) or a scanning line transition method (line permutation).

The video signal and PCM audio signal scrambled by the scrambling device 101 are supplied to the modulator 1.degree.2. The modulator 102 converts the PCM audio signal into, for example, a four-phase D
After being modulated using the PSK method, it is combined with a video signal, and the combined signal is further subjected to FM modulation.

The FM modulated signal from the modulator 102 is frequency-converted by a communication satellite transmitter 103 and then transmitted to the communication satellite 200.

Further, an FM modulated signal from communication satellite 200 is received by a CS antenna and a CS converter 301 that constitute a reception system 300 and is frequency-converted and then supplied to a CS tuner 302 .

The tuner 302 demodulates the FM modulation signal of the selected channel to obtain a video signal and a four-phase DPSK modulation signal. Furthermore, 4-phase DPS obtained by FM demodulation
Demodulation is performed on the K modulated signal to obtain a pit stream signal.

The video signal and pit stream signal from the tuner 302 are supplied to a descrambling device 303 where they are descrambled.

If the descrambling device 303 has the key information for unscrambling the video signal and the pit stream signal, the descrambling device 303 will normally perform descrambling and the original video signal SV and audio signal SA will be restored. and is normally viewed on the monitor 304.

By the way, in recent years, as information has become more sophisticated and diversified, in addition to video and audio information, printed information (facsimile information) that supplements and provides detailed explanations of such information has become available.
is becoming necessary.

To transmit such printed information, conventional facsimile communication using telephone lines has been relied upon.

For example, the 91st! As shown in FIG.
A facsimile device 104 is provided on the side, and a facsimile device 305 is provided on each receiving system 300 side, which is an individual communication destination.
4 and 305 are connected through a telephone line 400.

When transmitting printed information, the printed information is transmitted from facsimile device 104 to facsimile device 305 as a communication destination via telephone line 400 . A print screen (recording paper) 306 on which printed information is recorded is output from the facsimile machine a305.

Incidentally, although facsimile communication via the telephone line 400 is called broadcast communication, strictly speaking, the communication is not performed at the same time, and a time lag occurs. This time lag becomes larger as the number of communication destinations increases.

In addition, the more communication destinations there are, the longer it takes to communicate, and the longer the line is used, increasing the cost of communication.Furthermore, it is important to make sure that video signals, audio signals, and printed information are related to each other. However, video and audio signals are transmitted using communication satellites, while printed information is transmitted separately by facsimile communication, making transmission management complicated.

Therefore, it is being considered to transmit printed information using communication satellites. In this case, the communication system will be configured as shown in FIG. 10, for example.

In the figure, 105 is a facsimile signal generator. This signal generator 105 is supplied with print information Fl, and based on this print information 11F7, a facsimile signal S
l is formed. This facsimile signal Sl is supplied to the scrambling device 101 in synchronization with the clock CLK.

FIG. 11 shows the facsimile signal SrO frame structure.

Facsimile signal SI is 272 bits (34 bytes)
A data packet part PAC consisting of digital data, and a 16-bit data packet added to the beginning of this data packet part PAC.
It is in a packet format with a bit (2 hyde) mode control section MC. One frame is made up of 32 packets, and a 16-bit (2-byte) frame synchronization signal FC is added to the beginning of the frame. In other words, one frame consists of 9232 bits (1154 bytes).

In this case, the mode control unit MC determines whether the packet is a facsimile signal Sr.

Furthermore, the facsimile signal Sl packet includes a control signal packet and m#! There is a signal packet. FIGS. 12A and 12B show the packet structures of the control signal and the image signal, respectively. In the same figure, DA
T is an information data section, PFX is a prefix for identifying the information data section DAT, CRC is an error detection code, and CHC is an error correction check code.

The blifix PFX determines whether the information data portion DAT corresponds to a program selection signal, page end signal, program end signal, image signal, blank signal, or the like.

FIG. 13 shows the structure of the 8M selected bone. In this case, the information data section DAT is composed of 160 bits, DBI to DB20 are set in byte units, and codes of control items such as program number and page number are assigned in byte units.

The facsimile signal Sl is transmitted sequentially in frame units. In each frame, 16 bits of the frame synchronization signal FC are transmitted, and then 32 packets of signals are transmitted with 4-bit interleaving.

That is, in order to protect data against burst errors, the lower 4 bits of the 1st byte are sequentially transmitted from packet 1 to packet 32, as shown by the 11121st arrow A, and then the upper 4 bits of the 1st byte are transmitted sequentially. The bits are transmitted sequentially from packet 1 to packet 32, then the lower 4 bits of the 2nd byte are transmitted sequentially from packet 1 to packet 32, and so on, and finally the upper 4 bits of the 36th byte are transmitted sequentially from packet 1 to packet 32. 32 are sequentially transmitted.

Note that the 16-bit frame synchronization signal FC has no temporal variation, always has the same code pattern, and is not protected by additional bits for error correction.

The facsimile signal SI from the signal generator 105 is inserted into a predetermined area of the frame structure of the audio data, and
Scrambling is performed together with the audio signal based on the control signal SC.

In the transmission system 100, the other configuration is the same as the example shown in FIG. The FM modulated signal is transmitted to communication satellite 200 via transmitter 111103.

Further, in the receiving system 300, the video signal and pit stream signal from the CS tuner 302 are supplied to a descrambling device 303 to be descrambled, similar to the example in FIG.

If this descrambling device 303 has the key information for unscrambling the video signal and the U bitstream signal, the descrambling device 303 will normally perform descrambling, and the original video signal SV and audio signal will be restored. S
A and facsimile signal Sr are obtained.

The video signal SV and audio signal SA from the descrambling device 303 are supplied to a monitor 304, and the images and audio are reproduced and viewed.

Further, 307 is a printed information recording device, and this recording device 307 is supplied with a descrambling device ([-303 to supply a facsimile signal Sl and a clock CLK for sampling this signal Sl.
7 is configured as shown in FIG. 14, for example.

In the figure, the facsimile signal Sl and clock CLK from the descrambling device 303 are transmitted to the data acquisition unit 1.
supplied to This data acquisition unit 1 detects frame synchronization No. 18 FC from the facsimile signal SI and reproduces the frame synchronization signal, and data is acquired based on the reproduced frame synchronization signal 22 and deinterleaf processing is performed. It is done.

The deinterleaf-processed data output from the data acquisition section 1 is supplied to the signal processing section 2.

In this signal processing M2, signal processing such as error correction processing and discrimination between a control signal containing a program number, page number, etc. and an image signal is performed. Then, image signals of necessary programs and pages are supplied from the signal processing section 2 to the image receiving section 3, and printing is performed.

FIG. 15 is a diagram showing the transmission order of data for one program.

Here, the frame synchronization signal is a signal that includes only the frame synchronization signal FC for establishing frame synchronization.

In other words, it is a signal in which all data in the data packet section PAC in each frame is set to "O". The line selection signal is a signal for transmitting program numbers, page numbers, etc.
@Mi selection signal to information data section DAT (see Figure 13)
It consists of a control vs signal packet containing the following.

The image signal is composed of -) even if it is an image signal packet in which the image signal is included in the information data portion DAT. The page end signal is a signal indicating the end of one page's worth of image signals, and is composed of a packet of the control W signal in which the page end signal is included in the information data IIBDAT. The program end signal is a signal indicating the end of the image signal of the last page of the program, and is a control in which the information data section AT contains the program end signal. ! Consists of a double signal bucket.

The signal processing unit 2 in FIG. 14 has a reserved memory (not shown).
8 set numbers and page numbers of a plurality of programs to be printed are stored in advance by the user.

At the time of actual reception, the program number and page number included in the program selection signal of the deinterleaved facsimile signal S1 from the data acquisition unit 1 are changed from the program number and page number stored in advance in the reservation memory. When the two match, the m image signal is extracted, and the image signal is supplied to the image receiving section 3 to start printing. Then, when a page end signal or a program end signal is received, printing by the image receiving section 3 is stopped and the recording paper is cut.

[Problem to be Solved by the Invention] According to the number 1Ax and the @printing of the page number stored in advance in the reserved memory, the sent 8
If all programs are to be printed and sent only to specific recipients, the program numbers and U of all programs must be printed in advance.

Accordingly, the first and second inventions provide a facsimile receiving apparatus that eliminates the above-mentioned inconveniences and improves user-friendliness.

[Hands for Solving the Problems] This invention receives a facsimile signal transmitted 41111 times in which a program selection signal including at least a program @ number corresponds to an image signal, and based on an image signal extracted from this facsimile signal. A facsimile receiving device that performs printing includes a data storage memory that stores data for one frame of a received facsimile signal, a reservation memory that stores at least the program number of the program to be printed, and a reservation memory that stores at least the program number of the received facsimile signal. It is equipped with a microprocessor that identifies the program and extracts the image signal of the program to be printed.

The microprocessor includes a discriminating means for discriminating between a program selection signal and an image signal of the received facsimile signal, and a comparing means for extracting at least a program number from the program selection signal discriminated by the discriminating means and comparing it with the contents of the reservation memory. , a signal extracting means for extracting the image signal if the program is to be printed, and excluding the image signal if the program is not to be printed, according to the comparison result; A registration means for storing a number in a reservation memory, a reservation cancellation means for setting a cancellation flag corresponding to at least a program number stored in the reservation X memory, and a reservation for canceling the cancellation flag set by the -P cancellation means. Cancellation canceling means, mote switching for controlling the operation of the signal extracting means by switching between a first mote that extracts all the image signals of the received program and a second mote that extracts only the image TL signal of the reserved program. means.

[Operation] In the above configuration, the program number and page number of the received program are intentionally stored in the reservation memory.

Therefore, all received programs can be printed without storing all the program numbers and page numbers of all @ strings in the reservation memory 12 in advance.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1st t! 1 indicates the configuration of the main part of the signal processing section 2 (see figure 11114) in this fNt.

In the figure, 11 is a data storage memory.

This data storage memory 11 stores one frame worth of facsimile signal Sl that has been captured by the data capture section 1 and subjected to deinterleaving processing.

12 is a reservation memory, and this reservation memory 12 stores the program number and page number of the program to be printed.

Reference numeral 13 denotes a microprocessor, and this microprocessor 13 performs sampling processing of eight sets of image signals to be supplied to the image receiving section 3 (see FIG. 14) and printed. In this case, the image signal extraction modes include a mode (hereinafter referred to as "first mode") which extracts all the image signals of the received program, and a mode (hereinafter referred to as "first mode") which extracts only the image signal of the reserved program. Two modes are set: ``r second mode'').

In the first mode, the program number and page number are extracted from the facsimile signal SlO program selection signal stored in the data storage memory 11 and compared with the contents stored in the reservation memory 12.

If the same number & 1 number and page number are not stored in the reservation memory 12 and this is the first program received,
The R1 number and page number are stored in the reservation memory 12, and the picture R1 word of the received program is extracted.

If the same program number and page number are stored in the reservation memory 12 and it is not the first time received on the 8th morning, the image signal of the received program is extracted.

In the second mode, the program number and page number are extracted from the program selection signal of the facsimile signal S2 stored in the data storage memory 11 and compared with the contents of the reservation memory.

If the same program number and page number are not stored in the reservation memory 12 and the program is received for the first time, the program number and page number are stored in the reservation memory 12, and
Extracts the image signal of the received program.

If the same program number and page number are stored in the reservation memory 12 and it is not the first program received, it is determined whether the reservation has been cancelled.

If the reservation has been canceled, the received image signal of @kinu is excluded, otherwise the image signal of the received program is extracted.

Further, the microprocessor 13 performs processing such as cancellation of reservations and cancellation of reservations in accordance with the program number and page number stored in the reservation memory 12.

As described above, the microprocessor 13 performs image signal extraction processing, reservation cancellation, reservation cancellation cancellation processing, etc., and constitutes the following means (see FIG. 2).

That is, a discriminating means 131 discriminates between a program selection signal and an image signal of the received facsimile signal SI, and from the program selection signal discriminated by the discriminating means 131, a number "'1" is determined.
Comparing means 132 extracts the llZ issue and page number and compares them with the contents of the reservation memory 12. According to the comparison result in the comparing means 132, if there is a program to be printed, the image signal is extracted, and if the program is not to be printed, the image signal is extracted. a signal extraction means 133 for excluding image signals; a registration means 134 for storing in the reservation memory 12 the program number and page number of the program received for the first time according to the comparison result in the comparison means 132; The reservation canceling means 135 sets a cancellation flag corresponding to the programmed program number and page number, and the reservation canceling means 135 sets a cancellation flag corresponding to the number w1@ and page number stored in the reservation memory 12. A reservation canceling means 136 is configured to cancel the reservation, and a mote switching means 137 is configured to switch between the first mote and the second mote and control the operation of the signal extracting means 133.

Next, the operation of the microprocessor 13 will be explained based on FIGS. 3 and 4. FIG. 3 is a flowchart of program reception processing in the first mode, and FIG. 4 is a flowchart of program reception processing in the second mode.

At startup, it is the first mote, and the process shifts to the process shown in FIG.

In the figure, in step nl, the data storage memory 11
The program selection signal and the image signal are determined by the bfix PFX of each packet constituting the facsimile signal Sl stored in the program selection signal, and the program number and page number are extracted from the program selection signal and compared with the contents of the reservation memory 12. Let's do it.

Next, in step n2, when it is determined that it is the first received 8 silk, that is, when it is determined that the program number and page number are not stored in the reservation memory 12, the process moves to step n3, and the received program is stored in the reservation memory 12. The program number and page number are stored, and the process moves to step n4.

In step n4, the image signal for one screen of the received program is extracted and captured. This captured image signal is
The image is sent to the image receiving section 3 and printed out.

In addition, when it is determined in step n2 that the program number and page number are already received, that is, when it is determined that the program number and page number are stored in the reservation memory 12, the process moves to step n4 and the received s Extract and import the image signal of one screen of silk. This captured image signal is sent to the image receiving section 3 and printed out.

Further, when the mode switching means 137 switches from the $1 mode to the second mode, the process shifts to the process shown in FIG. 4.

In the figure, in step n1, the data storage memory 11
The program selection signal and the image signal are determined by the bfix PFX of each packet constituting the facsimile signal Sl stored in Make a comparison.

Next, in step n2, when it is determined that this is the first program received, that is, when it is determined that the program number and page number are not stored in the reservation memory 12, the process moves to step n3, and the program received in the reservation memory 12 is The program number and page number are stored and the process moves to step n5.

In step n5, the image signal for one screen of the received program is extracted and captured. This captured image signal is
The received image is sent to the received image 1i'B3 and printed out, and when it is determined in step n2 that it is the 8th morning that has already been received, that is, the 8th set number and page number are stored in the reservation memory 12. If it is determined that there is, the process moves to step n4.

If it is determined in step n4 that the reservation has not been canceled, that is, if it is determined that a cancellation flag has not been set corresponding to the program number and page number stored in the reservation memory 12, the process moves to step n5. Eight sets of received image signals for one screen are extracted and captured. This captured image signal is sent to the image receiving section 3 and printed out.

When it is determined in step n4 that the reservation has been canceled, that is, when it is determined that a cancellation flag has been set corresponding to the program number and page number stored in the reservation memory 12, the process moves to step n6. Eight sets of received image signals for one screen are excluded.

FIG. 5 shows an example of the contents of the reservation memory 12, in which the @m number, page number, and reservation cancellation flag are stored. For example, the reservation for the program with program number 011 and page number OI whose reservation cancellation flag is "1" has been canceled.

In this way, in the first mote, the microprocessor 13 extracts all the image signals received on the morning of August 8, and sends them to the image receiving section 3, where they are printed out. Therefore, by setting the mote to the first mote by the mote switching means 137, all the received programs can be printed out without the user having to previously store in the reservation memory 12 the 8 set numbers and page numbers of the programs to be printed. I can do it.

Furthermore, in the second mode, the microprocessor 1
3, image signals of programs whose reservations have not been canceled among the programs having the program numbers and page numbers stored in the reservation memory 12 are extracted and sent to the image receiving section 3, where they are printed out. Therefore, by setting the mode switching means 137 to the second mote and arbitrarily setting the program for which the reservation is to be canceled using the reservation cancellation means 135 and the reservation registration means 136, it is possible to print out only the program desired by the user. . Note that even in this second mode, if the received program is the first one, the 8th
The set is always printed out. This allows you to check the content of the program.

Here, consider a case where the facsimile signal Sl with the same program content is sent out multiple times.

In the first mode, the same program content is printed every time. In the second mote, the same program content is printed every time unless the reservation is canceled. When the same 8th morning content is printed every time, recording paper is wasted.

Next, another embodiment in which such drawbacks are eliminated will be described. Note that the explanation of the parts opposite to those of the above-mentioned embodiment will be omitted.

In this example, the first mote in the image signal extraction mode extracts the program number, page number, and update number from the facsimile signal SlO number selection signal stored in the data storage memory 11, and extracts the program number, page number, and update number from the facsimile signal SlO number selection signal stored in the data storage memory 11, and Compare with.

If the same program number and page number are not stored in the reservation memory 12 and this is the first received @sheath, the program number, page number, and update number are stored in the reservation memory 12, and the received program Extracts and processes image signals.

If the same 8 set numbers and page numbers are stored in the reservation memory 12, and it is not the first program received, it is determined whether the update numbers are the same and the content is the same @introduction. If the program contents are the same, the image signal of the received program is excluded, and if not, the image signal of the received program is extracted.

The second mote first extracts the program number, page number, and update number from the eight set selection signals of the facsimile signal Sl stored in the data storage memory 11, and compares them with the contents of the reservation memory.

If the program number and page number are not stored in the reservation memory 12 and this is the first received @sheath, the program number,
The page number and update number are stored in the reservation memory 12, and the received image signal on the 8th morning is sampled.

If the same program number and page number are stored in the reservation memory 12 and the program is not received for the first time, it is determined whether the update number is the same and the program content is the same. If the content of the program is the same, the image signal of the received program is excluded, and if not, it is determined whether the reservation has been cancelled.

If the reservation has been canceled, the image signal of the received program is excluded, and if not, the eight sets of received image signals are extracted.

Furthermore, in this example, the microprocessor 13 constitutes the following means (Second Book M).

That is, a discriminating means 131 discriminates between a program selection signal and an image signal of the received facsimile signal Sl, and a program number, page number, and update number are extracted from the program selection signal discriminated by the discriminating means 131, and the contents of the reservation memory 12 are extracted. Comparing means 132 for comparing, signal extracting means 133 for extracting the image signal if the program is to be printed, and excluding the image signal if the program is not to be printed, according to the comparison result in the comparing means 132; In accordance with the comparison result in 132, the 8th morning that was received for the first time is stored in the reservation memory 12, and the @8th morning that is not the first received 8th morning and that should be printed. a registration means 134 for storing a new update number for the reservation memory 12 in the reservation memory 12; a reservation cancellation means 135 for setting a cancellation flag corresponding to the program number and page number stored in the reservation memory 12; a reservation cancellation canceling means 136 for canceling a cancellation flag set in correspondence with the program number and page number stored in the program; and a mote for controlling the operation of the signal extracting means 133 by switching between the first mode and the second mode. It constitutes a switching means 137.

Next, the operation of microprocessor 3 will be explained based on FIGS. 6 and 7. 6(!l) is a flowchart of program reception processing in the first mode, and FIG. 7 is a flowchart of program reception processing in the second mote.

Next, in step n2, if it is determined that the received 8MI @subnumber and page number 8 are not stored in the reservation memory]2 and that this is the program received for the first time, step n3
The program number of the received program is stored in the reservation memory 12.
The page number and update number are stored, and the process moves to step n7.

In step n7, the image signal for one screen of the received program is extracted and captured. This captured image signal is
The image is sent to the image receiving section 3 and printed out.

If it is determined in step n2 that the same 8 set numbers and page numbers are stored in the reservation memory 12 and that this is not the first program received, the process moves to step n4.

In step n4, it is determined whether the update number is the same and the program content is the same. If it is determined that the program content is the same, the process moves to step n5 and the image signal of the received program is excluded.

If it is determined in step n4 that there is no identical @payment content, the process moves to step n6, where a new update number is stored in the reservation memory 12, and the process moves to step n7.

In step n7, the image signal for one screen of the received program is extracted and captured. This captured image signal is
The image is sent to the image receiving section 3 and printed out.

Further, when the mode switching means 137 switches from the first mote to the second mote, the process shifts to the process shown in FIG.

Make a comparison with

Next, in step n2, when it is determined that the program number and page number of the received program are not stored in the reservation memory 12 and that it was received for the first time on the 8th morning, the process moves to step n3, and the program number and page number of the received program are stored in the reservation memory 12. 8 silk number, page number and update number of the program that was broadcast are stored, and the process moves to step n8.

In step n8, the image signal for one screen of the received program is extracted and captured. This captured image signal is
The image is sent to the image receiving section 3 and printed out.

If it is determined in step n2 that the same program number and page number are stored in the reservation memory 12 and that it is not the first received 8 silk, the process moves to step n4.

In step n4, it is determined whether they have the same update number and the same program content, and when it is determined that they are the same program content, the process moves to step n5 to receive and eliminate eight sets of image signals.

If it is determined in step n4 that the program content is not the same, the process moves to step n6 and the reservation is canceled.
