[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile broadcast receiver that receives facsimile signals from broadcast radio signals and restores images.

0002

2. Description of the Related Art Facsimile broadcasting uses broadcast radio waves to transmit public information, such as newspaper information, other documents, graphics, and photographic information. Facsimile broadcasting is expected to become a powerful means of information transmission in the future, as it combines the characteristics of broadcasting, such as broadcasting, immediate reporting, and wide-area coverage, with the recording and archiving properties of print media. The above-described facsimile broadcasting is carried out by each broadcasting station inserting a corresponding program number for each program in the facsimile signal. In facsimile broadcasting in which such a facsimile signal and a program number added to each program of this facsimile signal are multiplexed and transmitted on a television broadcast signal,
Generally, a receiver receives a facsimile signal from a tuner and a demodulator, decodes it, and prints it on recording paper or the like. It is also designed to reserve facsimile broadcast programs and receive only those programs.

0003

[Problems to be Solved by the Invention] The above-mentioned conventional facsimile broadcast receiver takes at least 1 to 2 minutes to receive one program, and at most 5 minutes or more, and the length of each facsimile broadcast program varies. It varies. Therefore, since the length of each facsimile broadcast program is different, while receiving a facsimile broadcast program on one television channel, the broadcast time of another facsimile broadcast program on another television channel may vary. There are cases where the programs overlap, and in that case, there is a problem that the subsequent program cannot be received. Therefore, an object of the present invention is to provide a facsimile broadcast receiver that forcibly receives a preset program with a high priority when the broadcast times of a plurality of facsimile broadcast programs overlap.

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a format in which a facsimile signal and a program number added to each program of the facsimile signal are multiplexed and transmitted on a television broadcast signal. In a receiver that receives facsimile broadcasting, means for setting in advance the priority order of the program of the facsimile signal to be received and the program number as reservation information, and a method of continuously receiving the program of the facsimile signal currently being received. or determining means for determining whether to forcefully switch to reception of a program of another facsimile signal based on the reservation information; and switching means for switching from the program of the facsimile signal to the program of another facsimile signal.

[0005]

[Operation] Therefore, according to the present invention, by setting the priority order of facsimile broadcast programs, even if the broadcast times of multiple facsimile broadcast programs overlap, the program with a higher priority can be received, so that important programs can be received. can be received even when other programs are being broadcast by giving it a high priority.

It is composed of LCD5. Next, the operation of preferentially receiving the program currently being received will be explained using the flowchart of FIG. In FIG. 2, when the broadcast time of the reserved program for facsimile broadcasting comes, program reception (step 22) is started, and
When setting a program reservation, program reservation is started (step 30).

In receiving the program in step 22, first, the tuner 10 switches to the channel of the reserved program (step 23). Next, it is determined whether it is the broadcast time of another reserved program (step 24), and if so, the message "There was a program that could not be received" is displayed on the LCD 5 (step 25). Next, the facsimile signal is extracted from the demodulator 9 (step 26), the decoder 8 decompresses the code (step 27), the receiving mechanism section 2 feeds the paper, and the recording section 3 prints it on recording paper ( Step 28). Next, it is determined whether printing for one page has been completed (step 29), and if not, steps 24 to 28 are repeated. Furthermore, in the program reservation at step 30, the channel number is input from the keyboard 11 (step 31), then the program number is input (step 32), and then the start time is input (step 33). Next, it is determined whether the reservation has been completed (step 34), and if not, steps 31 to 33
repeat. Note that FIG. 7 shows an example of a reservation table for program reservation. The reservation table includes (1) a section for setting whether or not there is a reservation, (2) a section for setting the channel number, (3) a section for setting the program number, and (4) a section for setting the start time. ing. Set like this and RA
Stored in M7. In the example of FIG. 7, the setting is "program 123 on channel 1 is reserved from 1:30 p.m., and program 456 on channel 10 is reserved from 1:35 p.m.".

Next, the operation of preferentially receiving new programs will be explained using the flowchart of FIG. In Figure 3, when it comes to the broadcast time of the reserved program for facsimile broadcasting,
Program reception (step 42) is started, and when setting a program reservation, program reservation is started (step 51).
. In receiving the program in step 42, first, the tuner 10 switches to the channel of the reserved program (step 43). Next, it is determined whether it is the broadcast time of another reserved program (step 44), and if so, the recording paper is ejected by the receiving mechanism section 2 (step 45).
The tuner 10 is switched to a new program channel (step 46). Next, the facsimile signal is extracted from the demodulator 9 (step 47), the decoding section 8 decompresses the code (step 48), the receiving mechanism section 2 feeds the paper, and the recording section 3 prints it on recording paper ( Step 49). Next, determine whether printing for one page has been completed (

Repeat step 9. Furthermore, in the program reservation at step 51, the channel number is input from the keyboard 11 (step 52), then the program number is input (step 53), and then the start time is input (step 54). Next, it is determined whether the reservation has been completed (step 55).
), otherwise steps 52-54 are repeated.

Note that the reservation table for program reservation has the configuration shown in FIG. 7, similar to the case of FIG. 2. Next, using the flowchart of FIG. 4, an explanation will be given of the operation of switching between giving priority to the current program and receiving the new program. In FIG. 4, when the broadcast time of the reserved program for facsimile broadcasting arrives, the program is received (step 62).
), and when setting a program reservation, program reservation is started (step 73). In receiving the program in step 62, first, the tuner 10 switches to the channel of the reserved program (step 63). Next, determine whether it is the broadcast time of another reserved program (
Step 64), otherwise proceed to Step 69. If so, it is determined from the reservation information stored in the RAM 7 whether or not the current program should be prioritized (step 6).
5) If so, the LCD 5 displays "There was a program that could not be received." (Step 66). If not, the recording paper is ejected by the receiving mechanism section 2 (step 67), and the tuner 10 is switched to a new program channel (step 68). Next, the facsimile signal is extracted from the demodulator 9 (step 69), the decoder 8 decompresses the code (step 70), the receiving mechanism section 2 feeds the paper, and the recording section 3 prints it on recording paper ( Step 71)
.

Next, it is determined whether printing for one page has been completed (step 72), and if not, steps 64 to 71 are repeated. In addition, in the program reservation in step 73, a designation as to whether or not to give priority to the current program is input from the keyboard 11 (step 74).
), input the channel number (step 75), then input the program number (step 76), and then input the start time (step 77). Next, it is determined whether the reservation has been completed (step 78), and if not, steps 75 to 77 are repeated. Note that FIG. 8 shows an example of a reservation table for program reservation. The reserved table has (1
) A section for setting whether to give priority to the current program or not, (2) a section for setting whether or not there is a reservation, (3) a section for setting the channel number, and (4) a section for setting the program number. and (5) a part for setting the start time. The settings are thus set and stored in the RAM 7. In the example shown in Figure 8, "Specify that the current program is given priority, reserve program 123 on channel 1 from 1:30 p.m.
"Reserve channel program 456 from 1:35 p.m."

Next, the operation of receiving a program on a channel with a high priority will be explained using the flowchart shown in FIG. In FIG. 5, when the broadcast time of a reserved program for facsimile broadcasting arrives, program reception (step 82) is started, and when setting a program reservation, program reservation is started (step 94). In receiving the program in step 82, first, the tuner 10 switches to the channel of the reserved program (step 83). Next, it is determined whether it is the broadcast time of another reserved program (step 84), and if not, the process proceeds to step 90. If so, the priorities of the channels stored in the RAM 7 are compared (step 85), and if the priority of the channel of the current program is high, the LCD 5 displays "There was a program that could not be received." (Step 87). If not, the recording paper is ejected by the receiving mechanism section 2 (step 88).
, the tuner 10 switches to a new program channel (step 89). Next, the facsimile signal is extracted from the demodulator 9 (step 90), the decoding section 8 decompresses the code (step 91), the receiving mechanism section 2 feeds the paper, and the recording section 3 prints it on recording paper ( Step 92). Next, it is determined whether printing for one page has been completed (step 93), and if not, steps 84 to 92 are repeated.

[0012] Also, in the program reservation at step 94, the channel numbers are input from the keyboard 11 in descending order of priority (step 95), and then it is determined whether the channel has ended (step 96). If not, the process returns to step 95. Next, keyboard 1

Next, it is determined whether the reservation has been completed (step 100), and if not, steps 97 to 99 are repeated. Note that FIG. 9 shows an example of a reservation table for program reservation. The reservation table has (1) a part for setting channel priorities, and (2)
(3) a part to set the channel number, (4) a part to set the program number, (
5) Contains a part to set the start time. The settings are thus set and stored in the RAM 7. In the example of FIG. 9, "The priority order of channels is channel 1 and channel 10. Program 123 on channel 1 is reserved from 1:30 p.m., and program 456 on channel 10 is reserved from 1:30 p.m."
"Reservation by minute" is set. Next, the operation of receiving a program with a high priority will be explained using the flowchart of FIG. In FIG. 6, when the broadcast time of a reserved program for facsimile broadcasting arrives, program reception (step 112) is started, and when setting a program reservation, program reservation is started (step 124).

In receiving the program in step 112, first, the tuner 10 switches to the channel of the reserved program (step 113). Next, it is determined whether it is the broadcast time of another reserved program (step 114).
, otherwise proceed to step 120. If so, the priorities of the programs stored in the RAM 7 are compared (step 115), and if the current program has a higher priority, the LCD 5 will display "There was a program that could not be received."
is displayed (step 117). If not, the recording paper is ejected by the receiving mechanism section 2 (step 118), and the tuner 10 is switched to a new program channel (step 119). Next, the facsimile signal is extracted from the demodulator 9 (step 120), the decoding section 8 decompresses the code (step 121), the receiving mechanism section 2 feeds the paper, and the recording section 3 prints it on recording paper ( Step 122). Next, it is determined whether printing for one page has been completed (step 123), and if not, steps 114 to
Repeat 122. In addition, in the program reservation at step 124, the channel number is input from the keyboard 11 (step 125), the program number is input next (step 126), the start time is input (step 127), Next, the program priority is input (step 128).

[0014] Next, it is determined whether the reservation has been completed or not (
step 129), otherwise step 125
Repeat steps 128 to 128. Note that FIG. 10 shows an example of a reservation table for program reservation. The reservation table has (1) a section for setting whether or not there is a reservation, (2) a section for setting the channel number, (3) a section for setting the program number, and (4) a section for setting the program number.
It includes a part for setting the start time and (5) a part for setting the program priority. Set like this and RAM
