DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television broadcasting system, a television receiver, and a broadcast receiving method that facilitate use of a facsimile information service.

[0002]

2. Description of the Related Art With the spread of facsimile (Fax) devices to the general public, various facsimile information services have been provided in recent years. For example, various information such as company information, TV (television) program guide, fortune-telling, horse racing information, and product information are provided.

[0003] Therefore, information such as what information is provided and where it is important is important. Regarding the publicity for that purpose, a considerable amount of information is used not only in magazines, but also in some advertisements and personal computer communications. Data is being introduced.

[0004] Data reception by the "guidance method", which is a facsimile information service currently generally provided, will be briefly described. First, a call is made from a facsimile machine on the user side to a service center that provides necessary information as facsimile information based on a magazine or the like. When the user presses the dial button, the facsimile apparatus receives a DTMF (Dual Tone Multi).
(i. Frequency) signal to make a line connection.

On the user side, the facsimile apparatus generates a DTMF signal by the DTMF encoder based on the telephone number inputted by the key and sends it to the telephone line, and the public network side uses the line of this telephone number. To establish a line connection.

[0006] Once the connection is established in the voice call mode, the user operates the terminal according to the message of the other party to specify necessary information. The operation is performed by pressing the dial button (numerical value) of the facsimile apparatus, as in the case of calling, and the facsimile apparatus transmits a DTMF signal corresponding to the number to the telephone line side. If further selection is necessary, the necessary information can be finally specified by repeating this dial button operation. For example, in a facsimile information service that provides horse racing information, the information number information content is such that "01" is announced, "02" is odds, "03" is a run table, and "04" is a refund. If there was
A user who wants to know the run table presses the "0" and "3" buttons, and the corresponding DTMF signal is output.

[0007] When the final specification of information is completed, the start button of the facsimile machine is pressed. Then, the CPU in the facsimile apparatus that has received the instruction using this button,
It instructs the DTMF encoder and the fax modem to switch from the voice communication mode to the fax transmission / reception mode. This switching is performed together with the information providing device through the line control unit of the facsimile machine. Thereafter, the fax data is received, decoded, printed by the printing unit, and presented to the user.

[0008]

The conventional facsimile information service described above has a problem that the operation method for obtaining the information to be obtained is very complicated. That is, first, the number to be dialed must be obtained on a medium other than facsimile such as a magazine. Furthermore, the method of selecting information at the other end of the call was very primitive, such as listening to a voice guide and pressing the corresponding number with a dial button. The audio guide is difficult to hear or has to wait again if you miss it, as well as an overview of the information options provided (selection menu by number) and your choice It is difficult to understand the positional relationship of the parts that do. In addition, even though the information is obtained visually, the fact that the user is required to operate by hearing means that if the hearing is impaired, the service cannot be received normally. Also have.

Therefore, the object of the present invention is to
By using the data broadcasting function, fax information can be automatically used by the fax information service simply by selecting a program from the menu screen, without dialing by manual input or selecting operation by voice guide. Another object of the present invention is to provide a television broadcasting system, a television receiver, and a broadcast receiving method having a convenient facsimile information service receiving function.

[0010]

In order to achieve the above object, the present invention is configured as follows. That is, a signal for data broadcasting is multiplexed with a signal for television broadcasting and transmitted. At the receiving side, both signals are separated, reproduced by respective reproducing means, displayed on a display means, and used. In a broadcasting system in which data broadcasting is bidirectional using a telephone line as an up line and information can be bidirectionally exchanged by a data broadcasting program selection command operation on a receiving side, a plurality of fax information is held. A server which transmits the selected fax information in accordance with the selection instruction, and which is connected to the telephone line and connected to the calling side by dial connection, and of the stored fax information, the fax specified by the calling side. Fax information service server that sends information to the calling party, and the server provides the fax information service Broadcasting means for providing information and dial information and information for the selection instruction, a modem (modulation / demodulation) means provided on the receiving side capable of transmitting and receiving a fax signal, and a signal for broadcasting the received fax information signal. Converting means for converting the data into a reproduction signal format for displaying on the display means, operating means for selecting information of data broadcasting, and providing the selected fax information service by selecting a menu of the fax information service by data broadcasting Means for controlling connection to a telephone line at the beginning and controlling to request a service of the selected fax information when the line is connected.

In addition to functions such as giving a call to the user, the terminal controls the necessary communication control, including the operation procedure until the call is terminated and the line is disconnected.

The display device 110 is for displaying a video signal output from the video processing circuit 109 as an image. Further, the connection server 113 is for managing usage information and the like of the user of the data broadcasting, performing shopping for the data broadcasting, charging management of the pay information, and the like. In the case of using a service for providing an interactive program, a call is transmitted from the receiver 107 to the connection server 113. In this case,
A mechanism in which the new interactive program decoder 111 uses the public line 112 to transmit to the connection server 113, transmit necessary information, and transmit the necessary information from the connection server 113 to a broadcasting station. It has become.

The facsimile information service server 115 is a server which provides various kinds of information by facsimile and is connected to a subscriber line of the public network 120. For example, company information, TV program table, fortune-telling, horse racing information, and product information Required information such as a file that can be provided by facsimile, is called by a dialing call from a subscriber terminal of the public network 120, and transmitted from the calling side when connected to the calling side. A program selection management structure is provided for transmitting a program corresponding to the received program number to the calling side by facsimile information. The fax information service server 115 has a voice guide function so that it can respond to a call from the fax terminal, and can provide voice guidance for selecting a menu or its contents. For example, in the case of a facsimile information service that provides horse racing information, the program selection is performed by notifying information with information number information content “01”, odds by “02”, and “0” by “02”.
For example, the run table may be provided by "3", and the payout information may be provided by "04". If "03" is given, the information on the run table is transmitted to the line of the public network 120.

Facsimile information service server 115
Is also connected to the broadcasting equipment 100 via the network 114, and has a mechanism capable of providing management information for menu selection and program selection to the broadcasting station side.

In this system having such a configuration, radio waves in which a new interactive program and a television broadcast program are multiplexed are transmitted from the equipment 100 on the broadcast station side. That is, a new interactive program for data broadcasting is created by the new interactive program production device 102 in the facility 100 on the broadcast station side, and the created new interactive program is temporarily stored in the storage device 103. Thereafter, it is read out at a predetermined timing by the new interactive program transmission device 104, multiplexed with a normal television program transmitted from the television program transmission equipment 101 by the multiplexer 105, and transmitted by the television transmitter 106. You.

FIG. 2 shows the format when multiplexing is performed. “Hierarchy 1” is a television image signal at the transmission path level, 1H indicates one scanning line period, and V indicates a vertical blanking period. S1 in the vertical flyback period V indicates a VBI data signal portion, and the VBI data signal S1 is superimposed in a predetermined timing period in the vertical flyback period V. The VBI data signal is composed of a data line having a width of 297 bits, and this data line includes a synchronization unit and a data packet unit. This is the “layer 2” part.

The data packet includes a 14-bit packet prefix, a 176-bit data block, and an 82-bit check code. This constitutes the “tier 3” part. A data block includes a data group head and a data group. This constitutes “tier 4”.

Up to “layer 4” is a layer common to terrestrial data broadcasting, and layers above “layer 5”, which is a layer above it, differ for each service. Data broadcast commands, programs, and data are transmitted using the data blocks, and the receiving side separates and uses the television broadcast signal and the data broadcast signal from the individual received signals.

That is, the transmission radio waves multiplexed in the form shown in FIG. 2 are received by the receiving circuit 108 of the receiver 107, and the video of the broadcast program of the selected channel is displayed on the display device via the video processing circuit 109. The program is sent to 110 and the video of the program is displayed on the display device 110.

On the other hand, the data of the new interactive program multiplexed on the television broadcast program is sent from the receiving circuit 108 to the new interactive program decoder 111, where it is decoded and returned to the program and data.

The new interactive program decoder 111 is provided with an interpreter, a font, and basic image contents such as operation buttons in advance.
When the user instructs the data broadcast display using the remote controller 123, the remote control receiving system 121 receives the command and sends a program display instruction to the new interactive program decoder 111. Instructions and programs obtained by decoding from the data of
A screen is created based on the data and the like, and is provided to the video processing circuit 109.

The video processing circuit 109 divides the area of the television broadcast video and the screen of the new interactive program into, for example, the right half of the screen of the television broadcast and the left half of the screen of the new interactive program. The video signal is divided into video signals to be displayed on the screen in a distinguished manner and sent to the display device 110. As a result, the television broadcast and the new interactive program are displayed on the display device 110 in the form of a double screen with their areas divided.

That is, in the data broadcasting of the new interactive program, an instruction and a program for creating a screen and necessary data are transmitted as data for the new interactive program. Then, when the receiver (receiver) 107 receives and executes it, the receiver 107 generates a screen according to the instruction and the program, and displays the screen on the screen of the receiver to present to the user. . In a data broadcast, like a text broadcast, icons and buttons on the data broadcast screen can be operated by a remote controller attached to a receiver, and the functions given to the icons and buttons can be performed. For example, from the list of various services provided by data broadcasting on the menu screen, select the item of the service you want to use by moving the cursor by operating the remote control, and press the select button by operating the remote control to select the program for that service Is displayed on the screen, and the service is started to be used.

The programs and the like transmitted by data broadcasting are stored in a memory provided in the new interactive program decoder 111, and the related programs and the like are executed by the above selection operation to create necessary screens and present necessary contents. Will be done.

In the present system, one of the new interactive programs has a function of handing over a fax information service. The new interactive program production apparatus 102 uses a program for creating a menu screen of the fax information service and an individual fax information program. A screen creation program for selecting a fax information program, a telephone number for connection of the server providing the fax information program to use the selected fax information program,
Program data including data of an information number for extracting the selected fax information program is created, multiplexed with the television program via the new interactive program transmission device 104, and transmitted.

The new interactive program also has a shopping mall menu for catalog mail order and so on. If you register in advance, you can select the desired product on the screen and then press the "OK" button on the screen. By simply operating by operating the remote control, the telephone number of the mail order is automatically dialed, and an order is placed on the mail order server. Then, the order merchandise is separately delivered from the mail orderer to the address of the user registered as a member from the mail orderer.

Accordingly, the present receiver 107 for data broadcasting
Has a reception / playback system for data broadcasting and a communication control function for telephone, and the connection server 113 is used on the system side for member management, billing management and the like.

Here, an example of using fax information via data broadcasting, which is a feature of the present invention, will be described. Now, it is assumed that horse racing information is provided by a fax information service, and that the information is being provided by data broadcasting. The fax information service has the telephone number "03 (1234) 1
Provided by a fax information service server 115 connected to the public network 120 through a telephone line of number 111 ";
When horse racing information is used, for example, the information number is “01”
It is assumed that the user wants to know the start table, assuming that the information is "notification", "02" is "odds", "03" is "run table", and "04" is "refund".

In this case, the user operates the remote controller 123 to instruct the display of the data broadcast. Then, the receiver 10
The new interactive program decoder 111 creates a screen based on instructions, programs, data, and the like obtained by decoding from the data of the new interactive program.
Give to.

The video processing circuit 109 displays the video of the television broadcast and the screen of the new interactive program on the screen of the display device 110 as a double screen. Of course, the screen of the new interactive program may be displayed on one side.

The user operates the remote controller 123 to open the menu of the horse racing information fax service. Then, on the screen of the display device 110, buttons such as "notice", "odds", "running table", and "refund" are displayed.
Then, the user next operates the remote controller 123 to bring the cursor to the position of the button of the "running table". Then, when the “decision” operation is performed, the new two-sided program decoder 111 uses the operation information of the remote controller 123 to connect the telephone number information “0312341111” of the fax information service server 115 of the horse racing information and the information number “03” of the “running table”. Is output to the communication control system 122 together with the calling instruction. Then, the communication control system 122 controls the hooking according to the call command, and if the connection with the public network 120 is possible, generates the telephone number information “0312341111” by the TDMF signal. In response to this, the public network 120 recognizes the call to the telephone number “0312341111” and calls the line of the telephone number “0312341111”. That is,
Inform the fax information service server 115 of the incoming call. When the fax information service server 115 responds to this and starts the execution of the connection procedure, the communication control system 122 executes the connection procedure in response to this, and the two protocols match and the fax information service server 115 waits for the information number. At this stage, the communication control system 122 next transmits the information number “03” as a TDMF signal. In response to this, the fax information service server 115 recognizes that the target to receive the service is the "running table", reads out the fax information of the "running table" from the server 115, and reads out the public network 1
Send to 20. The signal of the fax information is sent from the public network 120 to the communication control system 122 of the receiver 107 via the line 112, and is passed from the communication control system 122 to the new interactive program decoder 111. The new interactive program decoder 111 decodes the facsimile information into image information, passes it to the video processing circuit 109, and turns it into a television image signal. Then, the fax information is displayed as an image on the display device 110. The user can read the contents of the facsimile information of the "running table" on the screen by using this image. The fax information service server 115, which has transmitted the fax information, executes a procedure for call termination processing, whereby the public network 120 disconnects the line and ends the call.

As a result, necessary facsimile information can be obtained by simple operations similar to conventional procedures for viewing a text broadcast or data broadcast, such as remote control operation of a corresponding button in a screen for program menu selection and information selection. As soon as you can see it, like the conventional fax information service, look up the telephone number of the line connecting the server that provides fax information, dial the phone number by dialing and connect the fax, Thereafter, it is not necessary to dial the program number of the information to be obtained according to the audio guide, so that the operability can be expected to be greatly improved.

The above-described automatic transmission processing for selecting the use of facsimile information from the data broadcast menu screen corresponds to the use of a new two-way program by data broadcast on the uplink. Then, when using the uplink, the new interactive program decoder 111 transmits a call to the connection server 113 using the telephone line 112 and the public network 120, and sends out necessary information. Further, necessary information is transmitted from the connection server 113 to the broadcasting station. In addition to the information exchange with the connection server 113, the telephone line 1
12. The above-described connection operation with the server 115 for providing the facsimile information service via the public network 120 is performed. Therefore, with the provision of the facsimile information, the user information including the new interactive program usage information is accumulated in the 113, and the information of the connection server 113 is used for billing management and totaling of the usage statistics information of the new interactive program. You can do it.

In this system, a broadcast station transmits a data broadcast program multiplexed with a television signal. The transmitted data broadcast (here, a bidirectional program) generally includes an execution instruction program and a bit map. It is an application consisting of such data. That is, the program is transmitted by broadcasting, and the receiver executes the program to display characters and graphics or operate in response to a user input.

Data broadcasting is one type of bidirectional communication. Transmission from a broadcasting station to the receiver 107 is a downlink of bidirectional communication, and transmission from the receiver 107 to the broadcasting station is bidirectional communication. Corresponds to the uplink. In the use of the downlink, on the receiver 107 side, the broadcast wave is received by the receiving circuit 108, the multiplexed new interactive program is decoded by the new interactive program decoder 111, and the video signal Processed with the program,
It is displayed on the display equipment 110 for observation and viewing.

When using the upstream line, the new interactive program decoder 111 transmits the necessary information to the connection server 113 by using the telephone line 112. Further, necessary information is transmitted from the connection server 113 to the broadcasting station. In addition, the telephone line 112 is also connected to a server 115 that provides a facsimile information service.

A data broadcast (here, an interactive program) transmitted by being multiplexed with a television signal is usually an application including an execution instruction program and data such as a bit map. That is, the program is transmitted by broadcasting, and the receiver executes the program to display characters and graphics or operate in response to a user input.

"Execution instructions" such as "where to display the menu", "what to do when each button is pressed", and "what to do when an unexpected operation is performed". The background pattern and the like of the menu button are configured as, for example, bitmap data as a program.

More specifically, an example of using a facsimile information service using the present system will be described with reference to FIGS. FIG. 3 is a flowchart for explaining one embodiment of the present invention, FIG. 4 is an example of a screen configuration corresponding to the processing flow in this flowchart, and FIG. 5 is an example of a decoder configuration for realizing them.

First, the operation procedure will be described with reference to FIGS. 3 and 4, and then the configuration and operation of the apparatus for realizing them will be described with reference to FIG. In FIG. 4A, reference numeral 200 denotes a TV program display screen displayed on the display device 110 of the receiver 107.

When the user selects, for example, the "data broadcast" button on the remote controller 123 while viewing a normal TV program (step S15 in FIG. 3).
0), the screen shifts to a screen like 201 in FIG. 4 (b), and a data program menu being broadcast is displayed. For example,
“Weather forecast”, “news”,..., “Fax information service” (step S151 in FIG. 3).

A facsimile information service 202 is displayed on one of them. When the user operates the “cursor move” and “select” buttons of the remote controller 123 to select the facsimile information service 202 in the menu (step S152 in FIG. 3), a menu of the facsimile information service is further displayed (FIG. 3). Step S of 3
154, S153).

For example, as shown at 203 in FIG. 4C, a list menu of information available through the facsimile information service is displayed. Of course, this is only an example, and the information may be classified by “genre” or may be arranged in the order of “above”.

When the button 204 of "horse racing information" is further selected (step S152 in FIG. 3), the screen is shifted to a screen 205 shown in FIG. 4D. Each menu item on this screen 205 (“Information” 206, “Race odds” 207,
The “running table” 208 and the “refund” 209) correspond to the information numbers and information contents described in the conventional example (steps S154 and S153 in FIG. 3).

When the user who wants to know the run table selects "run table" 208 by operating the remote controller 123 (step S154 in FIG. 3), this menu item does not correspond to a further lower menu. Since it corresponds to the information content provided by the facsimile information service (step S154 in FIG. 3), a DTMF signal is transmitted to make a call (step S155 in FIG. 3).

After connecting in the voice communication mode (step S156 in FIG. 3) as in the conventional example, a DTMF signal corresponding to the selected menu item is transmitted (step S157 in FIG. 3).

Conventionally, after listening to a voice guide in the voice call mode, an information number is selected by making a judgment based on the guidance, but here, the information selection has already been completed by menu selection on the screen. Therefore, there is no need to listen to the voice guide, and the DTMF signal can be transmitted.

Generally, in a facsimile information service,
Even if a DTMF signal is transmitted during voice guidance, a response can be received without any special problem. As described above, one of the features of the present invention is that necessary information can be selected by menu selection on the screen without hearing and making a decision. In addition, as is apparent from this operation flow, since the call is made to the public network after the information selection is completed, there is also an effect that the call time is short, that is, the call charge is small. Further, after switching from the voice call mode to the facsimile mode (step S158 in FIG. 3), the fax data is received (step S159 in FIG. 3).

Conventionally, the received data is decoded, printed, and presented to the user. However, in the present invention, this is performed as follows. First, the fax protocol is automatically converted to the data broadcast protocol (step S1 in FIG. 3).
60). The specific configuration of the conversion will be described later. Automatic conversion of a fax protocol to a data broadcast protocol means that receiving a fax and receiving a data broadcast are the same.

That is, it means that not only data broadcasting but also converted facsimile data can be processed by the data broadcasting reception processing unit described later. Thereby, there is an effect that the processing unit of the receiver can be shared. Further, the operability by the remote control operation and the menu selection on the screen as described above has an effect that it can be used at the time of receiving a fax similarly to the data broadcasting.

By converting the received fax information data into a data broadcast protocol, the information can be displayed on a television screen and handled with the same operability as data broadcast. FIG. 4E shows an example of the received fax information display. 210 is a screen, 211
And displays buttons for performing operations such as page forward / backward (212, 213) and enlargement / reduction of the display, and buttons for operating the remote controller 123. By operation, page forward, page back, enlarged display, reduced display of facsimile information data can be performed.

When a data broadcast is received, an icon or the like may be displayed on the screen to notify the user of the reception, but it is also possible to notify the reception of the fax in the same manner.

<Protocol Conversion Processing> The receiver of this system is compatible with television broadcasting and data broadcasting.
Since the fax data is different from the above, it is necessary to perform a fax-data broadcast protocol conversion process so that the fax information can be displayed on the display device 110 of the receiver.

Therefore, an embodiment of the protocol conversion for that purpose will be described next with reference to the flowchart of FIG. First, normal fax data is decoded (step S501 in FIG. 6). So-called MH / M
R / MMR decoding is performed to restore the image data. Next, the image data is encoded into a data broadcasting image format (step S50 in FIG. 6).
2). For example, the JPEG format is used.

Further, an object serving as a screen for browsing and operating the image data is created (step S503 in FIG. 6). For example, it is an HTML (Hyper Text Markup Language) file for displaying a JPEG file. The JPEG image display using the HTML file corresponds to 210 in FIG. In other words, it includes a fax reception image after conversion, and has a display layout and an operation menu.

The object created in step S503 may be created dynamically at the time of protocol conversion.
A predetermined template may be stored in a storage unit such as a ROM inside the receiver, and the converted image may be inserted and received at the time of reception, or an external storage device such as a CD-ROM and its drive may be used. The information may be provided using a medium, or may be multiplexed with a television broadcast and transmitted as a part of the data broadcast.

Next, header information necessary for a data broadcast application is added to this object to create data that can be handled as a data broadcast application (step S504 in FIG. 6).

Specifically, a header of a layer higher than “5 layers” of the data broadcasting layer shown in FIG. 2 is added. If the data broadcasting processing unit has an interface that can process without using an application header, that is, if the data broadcasting processing unit has an interface that allows direct input at the HTML file level in this example, a header is particularly added (FIG. It goes without saying that the processing of step S504) of No. 6 is unnecessary.

By performing the above-described fax-data broadcast protocol conversion process, data received as a fax can be handled in exactly the same way as data broadcast.

(Example of Using Terrestrial Wave) Next, a system configuration example in which a facsimile information service based on an interactive program is realized by using terrestrial waves is shown in FIG.
This will be specifically described with reference to FIG. FIG. 5 shows an example of the configuration of the new interactive program decoder 111 and the communication control system 122 in FIG. 2. 400 is a CPU, 401 is a data fetch error correction section, 402 is a ROM section, and 403 is a display control section. , 404 are a display memory unit, 405 is an input interface unit (input I / F), 407 is a modem (modulator / demodulator),

Among them, the synchronization separation section 410 is a circuit for separating the synchronization signal from the demodulated baseband video signal given from the receiving circuit 108 via the video input terminal 416, and the A / D conversion section. 412 is a video input terminal 41
The A / D converter converts the demodulated baseband video signal supplied from the receiving circuit 108 through the A / D converter 6 into a digital signal.

Further, the waveform equalizing circuit 411
10 is a circuit for performing waveform equalization processing on the digital signal output from the A / D conversion unit 412 while synchronizing with the synchronization signal separated at 10. This is for correcting a code error of data indicated by the waveform-equalized digital signal output from the waveform equalizer 411 while synchronizing with the synchronized signal thus obtained.

The CPU 400 is a control / processing center for executing a program, performing data processing, arithmetic processing, required control processing, and the like to realize viewing of a new interactive program. RO
The M unit 402 is a memory that stores programs to be executed by the CPU 400 and stores font data used for display. The work RAM 408 is a memory that is used for executing programs and temporarily storing data. The application RAM 409 is a memory storing application programs, the modem 407 is a modulator / demodulator for transmitting and receiving transmission signals between the public network and digital terminals, and the DTMF decoder 417 is a line controller 419.
A DTMF signal from the public network input through the network is converted into digital data and supplied to the bus 415;
The DTMF encoder 418 converts digital data provided via the bus 415 into a DTMF signal and provides the DTMF signal to the line control unit 419.

Under the control of the CPU 400, the line control unit 419 performs calls to the public network, transmission of dial numbers, transmission and reception of signals via the modem 407, transmission and reception of DTMF signals, and termination processing. Display control unit 403
Performs control such as writing and erasing data in the display memory unit 404 to display fonts and display image data under the control of the CPU 400. The display memory unit 404 Image data to be stored.

The input I / F 405 receives an operation command or the like given from the remote controller 123 via the remote control reception control system 121 and sends it to the CPU 40.
The color map memory 414 is a memory that stores a color map of the image data stored in the display memory unit 404, and the D / A conversion unit 41
Numeral 3 is for converting the data of the color map held in the color map memory 414 into digital data and outputting the digital data to the video processing circuit 109 as a display output.

In the case of terrestrial broadcasting, the new interactive program decoder 111 having such a configuration and the communication control system 122 are used. Then, data broadcasting is taken in as follows. <Capture of Data Broadcast> The demodulated baseband video signal is input from the receiving circuit 108 to the video input terminal 416. Then, the data separation data multiplexed in the video signal is fetched as error-corrected data by the sync separation circuit 410, the A / D conversion circuit 412, the waveform equalization circuit 411, and the data fetch error correction circuit 401.
400 stores this in work RAM 408.

When the user operates the remote control 123 for operating the receiver, for example, and selects the "data broadcast" button (step S150 in FIG. 3) in the state where the data broadcast data has been captured, the command input is performed. , The CPU 400 from the bus 415 via the input I / F 405.
Sent to

The CPU 400 executes a process for displaying a data broadcast according to this command, and
Reads data from ROM and stores necessary font data in ROM
The display data is read from the display control device 402 and written into the display memory 404 via the display control device 403 (step S151 in FIG. 3).

User input such as menu item selection (FIG. 3)
Step S152), selection of a corresponding process (Step S154 in FIG. 3), display update (Step S152 in FIG. 3).
153) is performed in this manner.

On the menu item screen shown in FIG.
When a user who wants to know the "running table" selects the running table button 208 by operating the cursor of the remote controller 123 (step S154 in FIG. 3), the user input is similarly performed by the CPU 4
Sent to 00. This menu item is
It is determined that the information does not correspond to the further lower menu but corresponds to the information content provided by the facsimile information service (step S15 in FIG. 3).
4).

As described above, the information “what is the processing corresponding to the menu item” is the information included in the data broadcast data. The CPU 400 recognizes that the start table button 208 on the menu item screen corresponds to the information number “03” provided by the facsimile information service, and that the facsimile information service is connected to any subscriber telephone number. Since the server can be identified from the data received by data broadcasting, C
The PU 400 sends the telephone number and the data of the program number “03” to the DTMF encoder 418, instructs transmission, converts the data of the telephone number and “03” into a DTMF signal, and gives the DTMF signal to the line control unit 419 together with a call command. Line controller 41
9 makes a call to the public network, and transmits a telephone number to the public network when the line is secured (step S155 in FIG. 3).

In this way, the line control unit 419 and the facsimile information service server are connected in the voice communication mode via the public network (step S156 in FIG. 3).

After the line is connected in the voice communication mode, C
The PU 400 gives a command to the line control unit 419 to transmit a DTMF signal of a program number corresponding to the selected menu item (step S157 in FIG. 3). conventionally,
After listening to the voice guide in the voice call mode, the information number is selected by judging based on it, but here, the information number “0” has already been selected by menu selection on the screen.
Since the selection of 3 ″ information has already been completed, the DTMF signal can be transmitted without having to listen to the voice guide.

Generally, in a facsimile information service,
Even if a DTMIF signal is transmitted during voice guidance, a response can be received without any special problem. As described above, one of the features of the present invention is that necessary information can be selected by menu selection on the screen without hearing and making a decision. Moreover, as is clear from this operation flow,
To make a call to the public network when you have completed the information selection,
There is also an effect that the call time is short, that is, the call charge is small. There may be a plurality of DTMI-transmissions required after the connection is completed. For example, "03"
After selecting, "04" as the "race number"
This is the case when you select.

In such a case, the CPU 400 stores the necessary DTMF in the internal register or RAM 408.
This can be dealt with by storing a number string “03, 04” to be output as a signal, and sequentially transmitting the number after connection is completed.

An appropriate interval may be required between the transmission of “03” and the transmission of “04”. This can be easily realized by controlling the timing of the instruction from the CPU 400 to the DTMF encoder 418. .

Further, CPU 400 instructs modem 407 and line controller 419 to switch from the voice communication mode to the fax mode (step S15 in FIG. 3).
8) Receive fax data (step S in FIG. 3)
159).

Conventionally, the received data is decoded, printed, and presented to the user. However, in the present invention, this is performed as follows. That is, the received facsimile data is input from the line control unit 419 to the modem 407 and demodulated here, and the modem 407 outputs the demodulated facsimile data to the bus 415. Therefore, the CPU 400 is controlled to store the data on the bus 415 in the work RAM 408.

Thus, the fax data is stored in the work RAM.
408. The stored fax data is
The facsimile protocol is automatically converted to the data broadcast protocol by the calculation by the CPU 400 (step S160 in FIG. 3). Specifically, this is as described with reference to FIG.

The converted received facsimile data obtained on the work RAM 408 in this manner can be handled exactly the same as the received data broadcast data stored in the work RAM 408 as described above.

That is, CPU 400 that actually performs the processing
The same processing can be performed irrespective of different types of data such as reception of video signal data via the bus 415 and reception of facsimile data via the modem 407.

Thus, there is an effect that a program for processing a program received as a data broadcast on CPU 400 can be commonly used for displaying and operating received fax data.

Furthermore, the operability by the operation of the remote controller 123 and the menu selection on the screen as described above has an effect that it can be used at the time of receiving a facsimile similarly to the data broadcasting.

By converting the received fax information data into the data broadcast protocol, the information can be displayed on a television screen and handled with the same operability as data broadcast.

The above description has been made on the ground wave data broadcast. However, a similar configuration can be realized when a general analog type CATV (cable vision) is used.

Numeral 7 restores the data ES to data executable by the CPU 400.

In such a configuration, the input terminal 800
