534 is a controller, 535 is a demultiplexing circuit, 536
Is a reception buffer.

Hereinafter, the operation of home terminal 5 will be described.

Now, in order for the home terminal 5 to use the broadcast of newspaper data from the newspaper branch office, it is necessary to first obtain a descramble key and set it in the descrambler 532.

To obtain the descramble key, for example,
After the contract with the dealer, the sales card receives the memory card storing the descrambler and the memory card driver 5
10 or purchase a disk-type recording medium recording a descrambler sold at a store,
This is acquired by taking it in through the disk device 516. Alternatively, it is obtained by accessing a predetermined contract center via the modem 518 and receiving a descramble key.

When the CPU 501 obtains the descramble key in this way, the CPU 501 transmits the descramble key to the control of the tuner.
A frequency channel for broadcasting a data frame storing newspaper data of a newspaper contracted to a descrambler via a 534 is set in association with a TDM channel.

On the other hand, when the subscriber sets the channel of the receiver 531 to the frequency channel on which the contracted newspaper is broadcast, the receiver 531 sets the TDM for the control frame.
The transmission frame (see FIG. 4C) transmitted on the channel is received and passed to the error correction circuit 533. The error correction circuit 533 uses the error correction code in the transmission frame,
Correct the transmission error. The error-corrected data of the transmission frame is directly written into the reception buffer 536, and
The frame shown in FIG.

On the other hand, the receiver 531 receives the transmission frame transmitted on the TDM channel for the data frame,
The error is passed to the error correction circuit 533. The error correction circuit 533 corrects a transmission error by using an error correction code in the transmission frame. The error-corrected data portion of the transmission frame is directly written on the reception buffer 536 for management information, and written on the reception buffer 536 via the descrambler 532 for newspaper data. Such a division can be realized by attaching a special identification flag before and after the newspaper data, identifying this by the receiver 531 and dividing the data. Alternatively, after associating the data section with the management information section,
You may make it broadcast using M channel. The descrambler 532 first descrambles using the descramble key set corresponding to the TDM channel of the frequency channel that has received the data frame.

The frame restored on the reception buffer 536
The demultiplexing and separation circuit 533 and the I / F circuit 513 are sequentially
Is sent to and stored in the RAM 503.

The CPU reads the control data portion (see FIG. 3) of the control frame sent to the RAM 503, and executes the following command when the terminal ID of the terminal itself is included. It is assumed that a command instructing registration of contract contents is stored in the control data.

In this case, the CPU 501 registers the information provider ID and the contract contents included in the data section in the RAM 503 as use permission information. However, already
If the usable information having the information provider ID included in the data of the system is registered, the usable information is rewritten with the newly received contract content.

On the other hand, when the data frame is sent to the RAM 503, the CPU 501 stores the management information in the management data section of the data frame and the use permission information registered earlier in the data frame.
A search is performed to determine whether there is a leading period including the type of newspaper and the information provider ID that match the newspaper type and the information provider ID included in the management information, and including the issue date included in the management information. If not, the data frame is discarded. On the other hand, when this is present, the newspaper data is included in the data portion of the data frame and recorded on the disk device 517.

After that, when there is an instruction to reproduce the newspaper data received from the subscriber, the CPU 501 first displays a list of directory files recorded on the disk device 517 on the display device 505. To the directory file, an attribute identifier that can be distinguished from other types of files is added to the file name. In addition, as the file name, a name that can recognize the newspaper corresponding to the directory file is given, for example, ** newspaper year / month / day / morning edition.

After that, when a directory file corresponding to the newspaper to be reproduced is designated on the displayed list from the subscriber via the input device 507, the CPU 501 reads the heading file described in the directory file, and reads the description. Displays a list of headings that have been set.

Next, when the headline is designated by the subscriber via the input device 507, as shown in FIG. 6, a page described corresponding to the headline is obtained, and the directory file is obtained. In accordance with the description of the layout described in the layout file described in (1), an element file such as an article or a photograph arranged on the page is read and displayed according to the described layout. At this time, the still image file is decoded using the still image decoder 511 and displayed.

In this display, if the region where the moving image file is associated with the layout file is specified by the subscriber, the corresponding moving image file is decoded using the moving image decoder 512, It is displayed in this area or the entire screen, and returns to the display when the display is completed or when a predetermined operation is performed. In addition,
It is desirable to display an area associated with a moving image file so that the user can recognize that fact. In addition, instead of a moving image file, a text file, a still image file, an audio file, and the like can be similarly reproduced and displayed in association with an area according to the designation of the area. However, when handling audio files, an audio decoder must be provided.

It is also possible to display a document file or a heading file of another document in the area, display the heading of the other document according to the designation of the area, and display this document. It is. In this way, a hierarchical newspaper can be realized.

Also, predetermined data and programs can be associated with the areas. For example, the advertiser's telephone number and order code are assigned to the area in the advertisement page, and the telephone number is transmitted to this telephone number via the communication control device and the ground line in accordance with the designation of this area. Alternatively, the order code may be automatically sent to the advertiser.

The CPU 501 also displays the next page, the previous page, and the designated page according to the operation of the subscriber.
Various display operations such as page display are performed.

Next, the store terminal 3 will be described.

FIG. 7 shows the structure of the store terminal 3.

The configuration of the store terminal 3 is the same as that of the home terminal 5, except that a plurality of disk devices are provided, and newspaper data is recorded in parallel by a plurality of disk devices.

The disk device 517 of the home terminal 5 and the store terminal is a recording / reproducing device for recording / reproducing a portable disk type recording medium such as a magneto-optical disk.

The light emitted from the LED array 1001 is refracted in the order of the plane mirror 1003 and the concave mirror 1004, passes through the lens 1002, and is visually recognized by the subscriber wearing the glasses-type display device. Here, the image visually recognized by the subscriber is a virtual image created by the concave mirror 1004, and the image is recognized by the subscriber several tens of centimeters away. Also, L
The image displayed simultaneously by the ED array 1001 is, for example, one line of a newspaper image. However, the LED array 10
01 repeatedly displays each line of the newspaper image at high speed,
The vibration motor synchronously rotates the plane mirror 1003 with the LED.
By vibrating so that the line displayed by the array 1001 is located at a position corresponding to the line in the image, a subscriber is visually recognized as if a newspaper image in a predetermined area is displayed at the same time. The operation of the display area can be performed using the operation key-10.
This is performed according to the input status of No. 12.

As described above, according to the present embodiment, newspapers can be distributed by broadcasting only to subscribers. In addition, the subscriber uses the above-described portable playback terminal in the same manner as a conventional newspaper. The distributed newspaper data can be used, for example, in a train.

Incidentally, the information distribution system described above may be modified and expanded as described below.

That is, in the above embodiment, the newspaper data was broadcast for each newspaper branch office. However, the local edition portion is collected from each branch office in the newspaper editing and distribution system 1 of the head office, and the newspaper edition and distribution system 1 of the head office is used. It may be broadcast nationwide. In this case, as shown in FIG. 11, the layout file, the document file, and the heading file obtained by synthesizing and editing the element file of the national version, the element file of the local version of each region and the corresponding local version are combined. The contract information to be transmitted to each point of sale terminal 3 and home terminal 5 is transmitted to each terminal as described above, with management information including local identification of the national version and the local version attached to each. Should include the identification of the local version to be received. Then, each point of sale terminal 3 and home terminal 5 receives and records only the management information having the national version identification or the contracted local version identification in the management information.

It should be noted that the newspaper data to be broadcast is simply taken in the data of the element file for each page, and the combined page is read.
It may be a set of data.

Next, in the above embodiment, the contents of the contract, that is, the information registered as the reception permission information in the store terminal 3 and the home terminal 5 are stored in the control frame and transmitted to the store terminal. 3. Although set in the home terminal 5, this may be performed as follows.

That is, after the contract with the store, a memory card storing the contents of the contract together with the descrambler described above is received from the salesperson, and the memory card driver 510 is received.
And register it as reception permission information, or purchase a descrambler sold at a retailer at a price according to the contract contents and a disk device recording the contract contents and register it as reception permission information. I do. At this time, the number of times that the newspaper data can be recorded may be included in the disc-type recording medium as the contract content. Then, each of the store terminal 3 and the home terminal 5 does not record the newspaper data corresponding to the contract content recorded on the disk-type recording medium other than the disk-type recording medium. Also, do not record more than the number of times included in the contract details.

When a predetermined contract center is accessed via the modem communication control device to receive the descramble key, the contents of the contract may be acquired and registered as usable information. In this case, it is preferable to use a system that is automatically charged by accessing the contract center.

The contract contents (reception permission information) stored in home terminal 5 may be encrypted. Then, a key for decrypting the encrypted data is transmitted together with the newspaper data included in the contract contents (reception permit information), and the data is decrypted by the key at the home terminal and the contract contents (reception permit signal) are transmitted. The recording may be performed only when the contents of the management information of the newspaper data match.

Next, in the above embodiment, each of the store terminal 3 and the home terminal 5 obtains the descramble key by a method other than the broadcasting. In the same manner as the contract content described above, the control frame may be transmitted to the individual store terminal 3 and the home terminal 5 by broadcasting. That is, the store terminal 3 and the home terminal 5 that acquire the descramble key broadcasted by the terminal ID may be controlled. In this case, each of the store terminal 3 and the home terminal 5 receives the descrambling key included in the data portion when the control data portion of the received control frame includes its own terminal ID. Is registered in the descrambler. By doing so, the key can be arbitrarily changed on the newspaper company side. Next, according to the distribution using the wireless transmission path, each dealer terminal 3, There is a case where the home terminal 5 cannot correctly receive the newspaper data. Therefore, for the treatment in such a case, the following may be performed.

That is, the newspaper editing and broadcasting system 2 of the newspaper branch office attaches an error detection code to each file constituting the newspaper data. And the newspaper editing and broadcasting system 2 of the newspaper branch
Broadcasts the same newspaper data several times. The store terminal 5 and the home terminal 5 check each file of the newspaper data on the RAM for errors, and if errors have occurred, discard them without recording them on the disk device and then broadcast the same. Record the file with the name.

Alternatively, the name of the file and the broadcast completion time included in the newspaper data scheduled to be broadcast are registered in each home terminal 5 in advance. If the corresponding file cannot be received even after the transmission completion time has passed, each home terminal 5 notifies the communication control device to a store or the like via the ground line 9. Note that such a scheduled transmission completion time is obtained from the newspaper editing and broadcasting system 2 of the newspaper branch in the data section of the file name and the broadcast scheduled completion time included in the newspaper data of the newspaper scheduled to be broadcast. By broadcasting a data frame in which data management information is stored in the management data section, the newspaper data can be sent to the home terminal 5 that receives the newspaper data. However,
In the management information, the fact that the information of the data part is information of the scheduled transmission completion time is described, and each home terminal registers the information of the data part as the scheduled transmission completion according to the description.

It is preferable that news articles in newspapers be updated in accordance with the progress of facts, similarly to television news. Therefore, in this embodiment, updating of an article is realized as follows.

That is, in the newspaper editing and broadcasting system, each file of the newspaper data is transmitted with the date and time of creation and the version number attached. When the home terminal 5 and the sales terminal 3 receive the newspaper data, they record the newspaper data on the disk device, and also create a table in which half of each file is associated with the name of each file, the creation date and time. On the other hand, when a file is updated along with the update of an article in the newspaper editing and broadcasting system, the date and time of creation and the version number are added to this file, and this is stored in the data section, and the newspaper data to which this file belongs is stored. A data frame in which the management information is stored in the management data section is transmitted. The home terminal 5 and the sales terminal 3 search the above-mentioned table by the name of the received frame, and if any of the same name has a different creation date / time and version number, it is recorded on the disk device. ,
The file with this name is updated with the received file, and the date and time of creation and the version number recorded in the table associated with this name are updated. On the other hand, name, creation date,
If all versions are the same, discard the received file. If there is no file having the same name, the file is newly recorded on the disk device, and the file name, date and time of creation, and version number are added to the table. When the first newspaper data is received, such a table can be created from the contents of the above-described document file.
Next, each newspaper data may be broadcast to each home terminal 5 from the store terminal 3 instead of the newspaper branch office. In this case, the configuration of the sales terminal 3 is the same as that of the newspaper editing and broadcasting system 2, and the sales terminal synthesizes and edits the newspaper data received by the newspaper editing broadcasting value step of the branch office and the advertisement requested for the sale. Broadcast to each home terminal 5.

By the way, it is convenient if the home terminal 5 and the portable reproduction terminal can use a dictionary for explaining the terms contained in the newspaper while displaying the newspaper.

Therefore, in this embodiment, such dictionary data may also be broadcast and made available to each home terminal portable terminal. That is, in this case, the dictionary data file is stored in the data frame and broadcast from the newspaper editing and broadcasting system 2 of the newspaper branch office in the same manner as the newspaper data. However, the management information in the management data section describes information indicating that the data included in the data section is a dictionary data file,
Each home terminal 5 can be handled as dictionary data. Further, it may be possible to add a term or revise a commentary of such dictionary data. Here, the dictionary data file is a record that describes the terminology.
Assuming that the set is a set of codes, the addition and revision can be performed as follows. In other words, data records for terms to be added or revised are made similar to dictionary data.
Each home terminal 5 adds this record to the dictionary file, or updates the corresponding record in the dictionary file with this record. Note that a program for using such dictionary data is recorded in advance in each home terminal 5 and mobile terminal. According to this program, the home terminal and the mobile terminal accept the designation of the term in the displayed newspaper by the above-mentioned input device or pen and access the dictionary data file according to the program, as shown in FIG. The commentary to be displayed is displayed in a window format. Next, in the above embodiment, the newspaper data is recorded after descrambling. However, the newspaper data may be recorded without descrambling and descrambled at the time of reproduction.

Next, in the above embodiment, a case has been described where only newspapers issued by one newspaper company are broadcast. However, this is because a plurality of newspaper companies and publishers May be used to broadcast publication data and various information in the same manner as newspaper data. Now, such newspaper data, publication data, and various types of information to which the subscriber subscribes to a subscription are collectively referred to as distribution data.

In this case, as shown in FIG. 12, a common center for broadcasting the contents of each broadcast is provided, and a specific frequency channel (referred to as a "common channel") is used. Information such as time and contents may be provided. The information of the common channel is not scrambled. Also, each home terminal,
With respect to the data frame received on this common channel, all the received contents are made available without control by the reception permission information, that is, without discarding.
The information on the common channel may be, for example, a guide video or the like. In this case, the home terminal 5 displays the received guide video in real time. Of course, the format may be text, voice, or another format, and the home terminal 5 processes the format by a method according to the information format.

As described above, when a plurality of newspapers and publishers broadcast distribution data of newspapers, publications, information, and the like using one or a plurality of frequency channels, the above-described contract contents are used. It is desirable to be able to further subdivide and enable detailed contracts. For example, your contract might include newspapers,
Classification of books, etc., information classes, etc. are provided. Then, the classification and the class are included in the management information given to the distribution data. The class may be arbitrarily determined by each information provider. For example, a class having general information or specialized information may be considered. Instead of providing a class for each distribution data, a class is provided for each element file of the distribution data and broadcasted. The home terminal 5 compares the usage permission information with the class for each element file, and records each element file. You may make it control. Of course, the same applies to the above-described newspaper data.

By the way, as such distribution data,
Similarly to newspapers and books, application programs and the like that can be used on the home terminal 5 and the portable terminal can be distributed.

In the information distribution system as described above, how to charge the contracted subscriber becomes a practical problem.

Therefore, in the distribution system described above, charging may be realized as follows.

That is, the CPU 501 manages the history of writing to the disk device 517 for each information provider. And at the time of the stand of the collector,
From the collector, a charge settlement memory card of the information provider in charge of the collector is received and inserted into the memory card driver 510. When recognizing the insertion of the charge settlement memory card, the CPU 501 writes the history of the recording received and performed from the information provider according to the information provider ID and the like recorded in the memory card in advance. The collector receives the memory card from the subscriber, and uses a portable memory card reader / writer as shown in FIG. 13 to record the name, recording time, class, etc. of the newspaper, book, etc. recorded by the subscriber. Read and recognize, calculate the fee, and collect. In FIG. 13, 1301 is a memory card driver, 1303 is a CPU, 1304 is a ROM, 13
05 is a RAM, 1307 is an input device, 1308 is a battery, 1302 and 1306 are I / F circuits.

Note that this portable memory card reading / writing device can write a descramble key or contract contents on the memory card at the time of contract, and pass it to the subscriber. Of course, a disk type medium may be used instead of the memory card. In addition,
Instead of the recording history, the reproduction history may be managed, and charging may be performed according to the reproduction status.

Next, the information distribution system as described above,
By remotely controlling the home terminal 5 using the above-described control frame, the home terminal 5 can be used for transmitting an emergency alert.

That is, on a specific frequency channel,
An alarm center or the like broadcasts an emergency alert and also broadcasts a control frame in which a command for instructing switching and reproduction of a receiving channel to a channel broadcasting the emergency alert is stored in all other frequency channels. In this control frame, a specific ID is stored as a terminal ID. On the other hand, each home terminal 5 previously stores this specific ID in addition to its own terminal ID, and executes a command of a control frame including this ID. In this case, the receiving channel is switched, and the emergency broadcast is received and reproduced. Alternatively, it operates according to the contents instructed by the control frame on the channel broadcasting the emergency alert, and reproduces the emergency alert. It is desirable that the broadcast of the emergency alert is a broadcast of audio data, and the home terminal reproduces the broadcast in real time using an audio decoder provided. However, of course, it may be a text, an image, or the like. As described above, in the information distribution system according to the present embodiment, the remote control of the terminal on the receiving side can be performed from the broadcasting side. Therefore, by utilizing this, the setup of peripheral devices of the home terminal 5 may be performed by remote control before the distribution data is broadcast.

Such remote control is performed, for example, by
