Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile broadcast receiving apparatus which reserves and receives a program of a facsimile broadcast.

[0002]

2. Description of the Related Art Facsimile broadcasting is a document which is produced by multiplexing a facsimile signal on a television broadcast wave.
It is a form of information transmission in which information such as graphics and photographs is broadcast and received by facsimile.

To receive a facsimile broadcast, it is necessary to reserve a desired program in advance. For that purpose, the user must first obtain the program guide.

[0004] When a program guide is obtained using a facsimile broadcast receiving apparatus, the program number of the program guide is manually input for each broadcasting station by a key input.

A conventional facsimile broadcast receiving apparatus will be described below with reference to the drawings.

FIG. 5 is a block diagram showing a schematic configuration of a conventional facsimile broadcast receiving apparatus, and FIGS. 6A and 6B are operation procedure diagrams showing a reservation operation procedure of a program guide in the conventional example and a table of the operation results. It is a display image figure which shows an example. FIG. 7 is a schematic diagram showing the contents of the reserved memory.

In FIG. 5, reference numeral 1 denotes an RF (R) which captures a television radio wave transmitted from a broadcasting station and inputs it inside the apparatus.
adio, frequency) input terminal, 2 a tuner section for extracting a facsimile signal from the television radio wave input from the RF input terminal 1, 3 a decoding section for demodulating the facsimile signal output by the tuner section 4, 4
Is a recording unit for recording the program content of the reserved program, 5 is a system control unit for performing all kinds of control of the apparatus main body, 6
Is a reservation memory for storing program information (channel, program number, update number, etc.) of a program to be reserved, 7 is a key input section for instructing program information of a reserved program by key input, and 8 is a reservation instruction in the key input section 7. The display unit 9 displays the operation result and the status, and 9 is a power switch for activating the main body of the apparatus.

The operation of the above conventional example will be described below. First, the user presses the power switch 9 to activate the device body. The operation of obtaining the program guide is performed by inputting the channel and the program number (0000) of the program guide using the key input unit 7.

For example, if it is desired to obtain the program guides of four channels, the reservation operation is started by pressing the [reservation] key for instructing the reservation operation, as shown in FIG. 6 (a). .. To make the first reservation and enter the 4-channel program guide, indicate 4-channel

Enter [0]. Finally, the [#] (eget) key for instructing the registration of the reserved program is pressed to complete the reservation operation of the program table. In this way, the program numbers in the program guide are input for the desired channels. The result of the reservation operation is displayed on the display unit 8 as in the display example of FIG.

When a program table reservation operation is performed by the key input unit 7, a channel number and a program number are stored in the reservation memory 6 as shown in FIG. 7, and the apparatus enters a standby state.

When a television radio wave is transmitted from the broadcasting station, the RF input terminal 1 receives it and inputs it to the apparatus main body. The tuner unit 2 extracts a facsimile signal from the television radio wave input from the RF input terminal 1, and the dude unit 3 demodulates it. The system control unit 5 detects the program information of the received program from the facsimile signal and compares the program information of the received program with the program information of the reserved program stored in the reservation memory 6. As a result of the comparison, if it is determined that the program guide is the reserved program guide, the system control unit 5 instructs the recording unit 4 to record the program guide. In this way, the user obtains the program guide.

The system control section 5 also extracts the update number when extracting the program information of the received program from the facsimile signal sent from the broadcasting station. This update number is a number for identifying whether or not the content of the program already transmitted and the content of the program to be transmitted next are the same, and is carried on the radio wave from the broadcasting station. The system control unit compares the program information of the reception number with the program information of the reservation number, and if they match, writes the update number of the program in the reservation memory 6. When the program guide is transmitted again from the broadcasting station, the system control unit 5 compares the update number of the newly transmitted program guide with the update number of the program guide written in the reservation memory 6. As a result of the comparison, if the update numbers are different, the system control unit 5 determines that the program list is new, and issues a recording instruction to the recording unit 4. When the recording unit 4 records, the user obtains a new program guide, not the already recorded program guide.

[0013]

However, such a configuration of the prior art requires a reservation operation when reserving a program table, and the operation is troublesome. Furthermore, the program change of the facsimile broadcast is irregular every half day but every week, and to obtain a new program table, you have to repeat a troublesome reservation operation every irregular program change. There was a problem that didn't happen.

Further, since the program number of the program guide is stored for each channel in the reservation memory, there is a problem that the capacity for storing other programs is reduced accordingly.

The present invention solves the above problems, and provides a fax broadcast receiver which can obtain a new program guide after a program change without making a troublesome reservation operation and can effectively use a reservation memory. The purpose is to

[0016]

In order to achieve the above object, the present invention provides a program guide memory in which program numbers of a program guide are stored in advance separately from a reserved memory, and the program guide is received only by turning on a power switch. It is configured to be in a standby state.

[0017]

According to the present invention, since the program number of the program table is stored in advance in the program table memory according to the above-described configuration, when the power switch is turned on, the apparatus immediately enters the standby state for receiving the program table. When each program is transmitted from the broadcasting station, the apparatus receives the program by the facsimile broadcast receiving section, the system control section detects the program information of the received program, and the program of the program table stored in the program table memory is detected. Compare with the number.
As a result of the comparison, when it is determined that the received program is the program guide, the system control unit issues a recording instruction of the program guide to the recording unit. Thereby, the user can obtain the program guide without performing the troublesome operation of the program guide reservation.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a facsimile broadcast receiving apparatus according to an embodiment of the present invention, and FIGS. 2A and 2B are memories showing an example of contents of a reservation memory and a program table memory used in the present invention. FIG.

In FIG. 1, parts having the same functions as those of the conventional example of FIG. 11
Is a program guide memory in which the program number (0000) of the program guide is recorded in advance and which is provided separately from the reserved memory 6.

The operation of the facsimile broadcast receiving apparatus of the present invention thus constructed will be described below.

First, the user presses the power switch to activate the device. Then, since the program number of the program guide is stored in advance in the program guide memory 11 as shown in FIG. 2 (b), this apparatus immediately enters the standby state for receiving the program guide. That is, the user does not need to perform any reservation operation when reserving the program table.

When a television radio wave is transmitted from the broadcasting station, this apparatus receives the television radio wave and inputs it through the RF input terminal 1. The tuner unit 2 automatically switches the frequency band every fixed cycle, picks up a television radio wave in the switched frequency band, and extracts a facsimile signal. The dude unit 3 demodulates the output of the tuner unit 2, and the system control unit 5 detects the program information (channel, program number, update number, etc.) of the received program from the demodulated facsimile signal. The system control unit 5 includes program information of the received program, program information of the reserved program stored in the reservation memory 6 (exemplified in FIG. 2A), and the program guide memory 1.
1 is compared with the program number (illustrated in FIG. 2B) of the program guide stored in the table 1. When it is determined that the received program is the program guide as a result of the comparison, the system control unit 5 causes the recording unit 4 to operate.
Instruct to record the program guide. At this time, since the system control unit 5 compares only the program numbers,
When it is determined that the program guide is the program guide, the program guide is recorded regardless of which broadcast station the program guide is.

As described above, the user can obtain the program guide only by pressing the power switch 9 without performing any reservation operation of the program guide. When the tuner unit 2 receives a facsimile broadcast at the moment or in the process of switching the frequency band, the tuner unit 2 cannot pick up the program even if the program of the facsimile broadcast is transmitted or the program is halfway. You may receive it. In this case, once receiving the program, the tuner unit 2 does not switch the frequency band and continues to receive the program. If the tuner unit 2 receives a program at the moment when the frequency band is switched, the tuner unit 2 cannot pick up the program.

FIG. 3 is a block diagram of another embodiment of the present invention in which a desired channel can be designated. 4A and 4B are memory schematic diagrams showing an example of a program guide memory provided with a reserved memory and a designated channel registration unit.

In FIG. 3, reference numeral 12 is a designated channel registration unit for registering a desired channel of the user, and reference numeral 13 is a selection switch for selecting whether or not the desired channel is designated.

The operation of this embodiment will be described below. First,
Press the power switch to start the device. When the user wants to obtain only the program guide of the specific channel, the selection switch 13 is turned on. Next, the desired channel is 4
If it is a channel, 4 channels are designated by the key input unit 7. Then, as shown in FIG. 4B, it is registered in the designated channel registration unit 12.

When the apparatus receives the program list of the facsimile broadcast, the system control section 5 compares the channel of the received program list with the channel registered in the designated channel registration section 12, and compares the program list of the designated channel with other channels. The program listing of the channel is sorted. That is, the system control unit 5 not only determines the program guide by comparing the program numbers of the received programs, but also registers the channel of the received program guide and the designated channel registration unit 12 when the received program is determined to be the program guide. Compare with the channel that is being used. Then, the system control unit 5 gives an instruction to the recording unit 4 to record the program guide of the designated channel. Therefore, even if the program guide is received, the program guide of a channel different from the designated channel is not recorded. Thus, when the user desires only the program guide of a specific channel, by turning on the selection switch 13 and designating the desired channel, the program guide of the other channels is not recorded, and the user does not want to record the program of the desired channel. Only the table is available.

[0028]

As is apparent from the above description, according to the present invention, the program guide memory in which the program numbers of the program guides are stored in advance is provided separately from the reserved memory. Since the reception standby state is set, it is not necessary to perform a troublesome operation when reserving the program guide. That is, the user can obtain the program guide just by turning on the power switch.

Furthermore, since a program guide memory is provided separately from a reserved memory used for reserving ordinary programs, the reserved memory has a free space for storing program information of the program table, and the reserved memory can be effectively used. It has the effect of being able to.
