Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data broadcasting system for receiving a large amount of data from a center device by using terrestrial broadcasting waves, satellite broadcasting waves, FM broadcasting waves and the like, and a terminal device for the same.

[0002]

2. Description of the Related Art As is well known, with the digitization of television signals (from signal processing to transmission), a system for providing a large number of programs to each home has been developed. This large number of programs are sent by data broadcasting.

Data broadcasting uses video channels of television broadcasting (including high-definition television) currently performed by satellite, terrestrial, etc., and uses video, audio, computer software, game software, newspapers and newspapers. It is a broadcast that transmits various digital signals including huge data such as magazines. Note that these digital signals are compressed and modulated.

In recent years, the transmission of information has been sped up and a large amount of data can be received quickly. On the other hand, as a terminal device that uses the above-mentioned data, a small and portable personal digital assistant (PDA) for personal use is becoming widespread, and a mobile terminal similar to the currently widespread radio broadcasting. Digital data broadcasting for devices has become possible.

In such data broadcasting, there is a method for a user of a terminal device to obtain desired data from a large amount of data provided. First, the first method is to receive data that is unilaterally transmitted (drained) to each home from the data transmission station side, store it in the memory once, and then
This is a method in which desired data is selected by reading from the memory by the selection function of the terminal device. The second method is a method in which a user of the terminal device accesses the data transmitting station side by a communication means by operating the terminal device, requests transmission of target data, and downloads desired data.

FIG. 15 shows a broadcasting system in such a conventional data broadcasting. The broadcasting system shown in FIG. 15 adopts the first method. In FIG. 15, reference numeral 11 in the figure is a data transmission station,
Data of computer software, game software, newspapers / magazines, etc. are multiplexed, superimposed on a television signal, and transmitted via a broadcasting satellite 12 to a terminal device of each home 13 on the receiving side. On the other hand, in the standard system of standard television broadcasting by the broadcasting satellite 12, sound is transmitted by digitally modulating multiple subcarriers.

FIG. 16 shows details of the terminal device in each home 13. That is, in each home 13, the television signal transmitted from the data transmission station 11 via the broadcasting satellite 12 is a BS (Broadcast Satellite).
It is received by the antenna 131. The television signal received by the BS antenna 131 is supplied to the BS reception circuit 132. The BS reception circuit 132 performs demodulation processing on the supplied television signal, and outputs a bit stream corresponding to the signal thus obtained, to the data packet extraction unit 13.
It is output to 3.

The data packet extraction unit 133 identifies and extracts data packets assigned to data such as video, audio, computer software, game software, newspapers and magazines from the bit stream. The extracted data is supplied to one input end of the information type comparison unit 134.

Here, the user selects a desired information type with an input device (not shown), and the selection result is stored in the acquired information type input section 135. The information type stored by the acquired information type input unit 135 is the information type comparing unit 1
It is supplied to the other input terminal of 34.

Then, the information type comparison unit 134 compares the data from the data packet extraction unit 133 with the information type from the acquired information type input unit 135, outputs the target data packet to the display control unit 136, Display it on a television screen, etc.

FIG. 17 is a flow chart for explaining the operations of the information type comparison unit 134 and the acquired information type input unit 135. That is, when the user starts by selecting an information type with an input device such as a remote controller (step S11), the acquired information type input unit 135
Determines in step S12 whether or not the information type has been input. When it is determined that the information type has been input (YES), the acquired information type input unit 135 stores the input information type in step S13, and the stored information type is stored in the information type comparison unit 134. sending.

When it is not determined that the information type has been input (NO), the acquired information type input unit 135 determines whether the information type has no signal or the stored information is the information type comparing unit 134.
It is being sent to Dr.

Next, the information type comparing section 134 determines in step S14 whether or not the data packet from the data packet extracting section 133 has been input. When it is determined that the data packet is input (YES), the information type comparison unit 134 compares the data packet with the information type stored in step S13 in step S15.

If it is determined that the data packet has not been input (NO), the information type comparison unit 134
In step S15, the input waiting of the data packet is executed. Then, in step S15, the information type comparison unit 134 compares the data packet with the information type stored in step S13, and determines whether the content of the data packet matches the information type. Here, if the content of the data packet matches the information type (YES), the information type comparing unit 134 proceeds to step S16.
Then, the data packet is sent to the display control unit 136 for display on a television screen or the like. If the content of the data packet does not match the information type (NO), the user again inputs the desired information type to the acquired information type input unit 135 in the process of step S12.

However, in the conventional broadcasting system for data broadcasting as described above, even if the data to be provided has a large capacity, the number of channels, the number of data or the number of programs are limited, and the data required by the user is limited. Alternatively, the program is not always provided at a convenient time. On the other hand, the data transmitting station 11 has no means for detecting the data or program required by the user, so that flexible data or program organization is not possible. . In addition, when the capacity of data to be provided is increased, the terminal device body requires a large-capacity memory device.

If a communication device (not shown) for exchanging information with the data transmission station 11 is provided in the terminal device of each home 13, the user must perform a special operation.
In addition, the user needs to know in advance the content (organization) of the program currently being broadcast. Further, in the communication device, when requests from the data transmitting station 11 are concentrated from a large number of terminal devices or when the number of users in the data broadcasting area fluctuates, the request response from the users deteriorates. Therefore, it will take a long time to realize the request from the user. Further, the data transmission station 11 cannot simultaneously transmit to many terminal devices.

Further, when the above terminal device is portable for carrying around, if the terminal device is equipped with a BS antenna, a tuner, etc., the circuit becomes complicated, which increases the size and size of the structure.
There is a problem of causing economic disadvantages.

On the other hand, although it is different from the above-mentioned configuration, bidirectionally accessible wired data communication represented by the Internet such as CATV (cable television) and CCTV (closed circuit television). In the field of, there is a global wide area information system called WWW (World Wide Web). The data used for this is HTML (Hyper Text Markup Language).
Is described. This takes the form of using a markup tag to describe the logical structure of a document, and also uses URL (Uniform
It is characterized in that it is described by a uniform file name called source Locator). In particular, the URL is scheme:
By taking the structure of / host. Domain / path / filename,
The location of the target file (what file name on which server) can be specified on a global scale.

That is, a server station having a server is arranged in each area, and each server station and each terminal device are connected by a wide area network. Further, each server station and each terminal device respectively have bidirectional communication means for communicating with each other.

Then, in the terminal device, the user only needs to specify a specific location of the document displayed on the screen, and the link information associated with the location can be easily used to transmit the document via the network. A document can be displayed on a television screen or the like by transmitting a file acquisition request signal to the server station and receiving a signal from the server station.

Therefore, FIG. 18 shows the display screen of Toshiba WWW server, and FIG. 19 shows the contents of the HTML file. Here, the image data of the first planet in FIG. 18 is “<IMG SRC =” / imgdat in FIG.
It corresponds to the description of /icon/s-dot/contents.gif ”>, and / imgd in the same server as the document file server for the main text.
It indicates that the contents.gif file in the at / icon / s-dot / directory is a planet image file.

When the user specifies, for example, the "coffee break" portion in the document shown in FIG.
"<AHREF =" COFFEE / index-j.html "> Coffee break </A> ... reading and essay <BR>” in 9
CO description for the same server on the network
Instruct to send the FFEE / index-j.html file. Then, the received file is displayed on the screen. In this way, documents can be received and displayed one after another with a simple operation.

On the other hand, when the same service is taken into consideration in the data broadcasting service by wireless or the like, it can be achieved by describing the contents corresponding to the above-mentioned URL with the channel number, the broadcasting company, the program name, etc. Is easily imaginable.

However, in the data broadcasting service, the flow of information is only in one direction, that is, the terminal device cannot actively request the information, so that the unspecified number of terminal devices are
It is generally used for the purpose of transmitting a large amount of the same information (weather forecast, stock price information, information on horse races, music information for karaoke, etc.). Is not suitable for. This means that even if the user specifies a specific location of the document displayed on the screen, it is unknown whether the document file embedded in the link information will be sent immediately, and the data will be sent. Until the time comes, the next display cannot be displayed, and there is the inconvenience that the system becomes a poor response for the user.

[0025]

As described above, in the conventional data broadcasting system, when the terminal device is used as a portable device, if the BS antenna, the tuner and the like are provided, the circuit becomes complicated, and the configuration and There is a problem that the shape becomes large and causes an economical disadvantage. In addition, it is difficult to realize a system according to the usage situation. Furthermore, even if the user specifies a specific location of the document displayed on the screen for the terminal device using hypertext, the next display cannot be made until the data is sent, and the user cannot It has the disadvantage of becoming a system with poor response. An object of the present invention is to provide a data broadcasting system which can quickly provide suitable and necessary information to a user according to various usage situations, and can be downsized to a terminal device and suitable for portability.

First, the user selects designated personal information to be transmitted to the main device 31 of the data transmission station from the personal information stored in the second non-volatile memory 447 automatically or manually depending on the past usage situation. . Then, the main processor 444 sends the selected designated personal information to the communication control processor 432 via the interface 42, and stores the personal information in the first nonvolatile memory 433. Then, when the personal information transmission request signal from the data transmission station main device 31 side is received, the communication control processor 432
Is the first regardless of the operating state of the main processor 444.
The personal information stored in the volatile memory 433 is promptly transmitted to the data broadcasting station main device 31 via the communication circuit 431.

FIG. 9 is a flow chart for explaining the operation of the communication control processor 432. First, when started (step S51), the communication control processor 4
In step S52, the process 32 determines whether or not there is a response from the data transmission station main device 31. And
When it is determined that there is no response from the data transmission station main device 31 (NO), the communication control processor 432 waits for a response from the data transmission station main device 31. If there is a response from the data transmission station main device 31 (YES),
In step S53, the communication control processor 432 sends a communication line connection request to the data transmitting station main unit 31.
Then, the communication control processor 432 causes the step S54.
Then, the data transmission station main device 31 is connected by a communication line such as a wireless communication.

Then, in step S55, the communication control processor 432 drives the built-in timer (not shown) and waits for the elapse of the predetermined time Ts, and then the data transmission station main unit 31.
Wait for a response from.

Next, in step S56, the communication control processor 432 determines whether or not the response from the data transmission station main unit 31 is a personal information transmission request. Here, when it is determined that the request is not the personal information transmission request (NO), the process returns to step S55.

When it is determined that the request is for transmitting personal information (YES), the communication control processor 432 sends the personal information to the data transmitting station main device 31 in step S57, and then in step S58, the data is transmitted. Transmitting station main unit 3
The communication line connected to 1 is disconnected, and step S is performed again.
It returns to the process of 52.

In step S55, the fixed time T
When s has elapsed (YES), the communication control processor 432
Stops the operation of the built-in timer, disconnects the communication line connected to the data transmission station main device 31, and returns to the process of step S52.

As described above, according to the sixth embodiment, the data transmission station main unit 31 can promptly send a transmission request regardless of the operating state of the portable terminal unit 41 itself in the broadcast area. Privacy is protected by separating the personal information stored in the first non-volatile memory 433 from which the personal information can be automatically read and the second non-volatile memory 447 that cannot be read from the data transmission station main device 31 side. At the same time, it is possible to improve the responsiveness to the transmission request from the data transmission station main device 31 side and to have good operability.

FIG. 10 shows details of the terminal device according to the seventh embodiment of the present invention. In FIG.
The broadcast data D1 received by the antenna 51 is demodulated by the receiving circuit 52 into received data D2. This received data D
2 is supplied to the link information analysis circuit 53 to generate the display data D3 and is supplied to the display circuit 54. The display circuit 54 converts the display data D3 into display data D4 that can be displayed on the screen, and outputs the display data D4 to the display 55 with a touch panel function. On the display 55 with a touch panel function, home electric appliances for shopping, event information and the like are displayed.

On the other hand, the link information analysis circuit 53 analyzes the link information in the received data D2, and in the subsequently received broadcast data D1, the data D5 adapted to the link information.
Are transferred to the data memory 56. Data memory 56
Stores the data D5 together with the file name. The stored data is supplied to the link information analysis circuit 53 as display data D6, and is displayed on the display 55 with a touch panel function. On the other hand, if the link information indicates another channel, the link information analysis circuit 53
The reception channel control signal S1 is output to the reception circuit 52,
Select the desired channel.

Here, when the user operates the touch panel on the display 55 with a touch panel function to select desired data, the display 5 with a touch panel function is displayed.
5 recognizes which file is selected from which position information, and supplies the selected target information to the link information analysis circuit 53 as the access information D7. Then, the link information analysis circuit 53 inquires whether the target file exists in the data memory 56, and if there is, the reception circuit 52.
The data D6 is read from the data memory 56 and output to the display circuit 54 without waiting for the received data D2 from the device. In this way, the next data can be displayed at high speed.

Therefore, according to the seventh embodiment, the link information described in the received document is used to establish the link before the user actually gives an access instruction. The data D5 is stored in the data memory 5 in the terminal device.
By incorporating in 6, the document can be displayed immediately when actually instructed by the user.

FIG. 11 shows an eighth embodiment of the present invention. In FIG. 11, the same parts as those in FIG. 10 is different from FIG. 10 in that it is displayed on the display 55 with a touch panel function so that the user can judge whether or not the following linked information and document data have been taken into the terminal device. The points are different. That is, the link information analysis circuit 53 determines that the data D5 matching the link information in the received data D2.
Is transferred to the data memory 56, and at the same time, the display circuit 5
4 supplies the received link information name.

The display circuit 54 displays the display of the corresponding item portion on the display 55 with a touch panel function, which is already displayed, in distinction from other items (in the figure, shaded display). In this way, the user can recognize whether the data that follows immediately after selecting the next item is displayed.

That is, according to the eighth embodiment, whether or not the next linked information, document data, and the like have been taken into the terminal device is changed by changing the display color of the portion or by a frame. By notifying the user by means such as surrounding or blinking, it is possible to know immediately when the document is displayed when the portion is designated.

FIG. 12 shows a ninth embodiment of the present invention. In FIG. 12, the same parts as those in FIG. The difference from FIG. 10 is that the received broadcast data D1 is stored in the data memory 56 as much as possible together with the creation date and revision number thereof. Then, a means for displaying on the display 55 with a touch panel function is provided so that the user can judge whether or not these are the same as those currently being broadcast.

That is, on the data transmitting station side, the revision number is added to the link information included in the received data D2 in addition to the contents corresponding to the file name. A revision number is also added to the received data D2.

Further, the data D5 stored in the data memory 56 is retained in the data memory 56 without being erased as long as the capacity for storing the data remains. Then, when the same display 55 screen with a touch panel function is displayed again (for example, a shopping screen), the link information analysis circuit 53 establishes a link with the revision number of the file already stored in the data memory 56. The revision number of the existing file is compared (for example, the latest file is rev2.0), and the file name of the old link information is supplied to the display circuit 54. The display circuit 54 distinguishes the display of the corresponding item portion on the screen of the display 55 with a touch panel function from other objects (hatched display in the figure).

In this way, when the user selects the next item, the immediately following data is displayed, but the user can recognize that the data is old. This is effective when there is almost no difference in the contents of most of the contents such as catalogs of products and information on events and the latest files.

That is, according to the ninth embodiment, the link information D5 included in the reception data D2 received in the past is stored in the data memory 56 together with the creation date and the revision number as much as possible. , The next document can be displayed with high probability. Then, the contents corresponding to the conventional URL are added to the contents such as the channel number, the broadcasting company, the program name, the file name, etc., as well as the creation date and revision number information. It is possible to determine whether the data stored in the data memory 56 in the terminal device and the data to be received are the same data.

Here, even if it is determined that the information is old, the next document can be displayed with a higher probability by displaying it on the screen of the display 55 with the touch panel function. If the data stored in the data memory 56 is old, the user can specify the part by notifying the user by changing the display color of the related part in the document, enclosing it with a frame, or blinking it. It is possible to notify the user whether or not the content of the document displayed when doing is the latest.

FIG. 13 shows a tenth embodiment of the present invention. In FIG. 13, the same parts as those in FIG. 10 is different from FIG. 10 in that the information linked by the link information analysis circuit 53 is checked for suitability, for example, by region or contract, and only the link information matched by the display circuit 54 is displayed on the display 55 with a touch panel function. The difference is that it is displayed on the screen and the access of incompatible data is restricted.

That is, on the data transmitting station side, for example, service area information is added to the link information in the received data D2 in addition to the content corresponding to the file name. Then, the link information in the received data D2 to which the service area information is added is stored in the link information analysis circuit 53.
Here, for example, in the case of a terminal device installed in Tokyo,
The display circuit 54 performs a display process of displaying an item for which the link information of the regional data of / tokyo or / japan is designated on the display 55 with a touch panel function.
The display circuit 54 does not perform the display process when the link information of / saitama is specified.

In this way, even if the same "shopping document data" is broadcast, an appropriate display is made by the receiving terminal device, which is not only easy for the user to use, but also
The program provider does not need to prepare individual data.

Therefore, according to the tenth embodiment, in addition to the information corresponding to the file name, the contents corresponding to the conventional URL are subject to restrictions (for example, specific area, contract By adding the information indicating the type, use of the terminal, etc.), the displayed information such as a character in the received document is linked to the area information and contract type content of the terminal device. It is possible to check whether or not they are compatible and display only the compatible link information on the screen 55 with the touch panel function. Further, in the tenth embodiment, since it is sufficient to send one document data having the same link information to all the terminal devices, it is possible to manage and reduce the amount of transmission data.

FIG. 14 shows an eleventh embodiment of the present invention. In FIG. 14, the same parts as those in FIG. The difference from FIG. 10 is that, with respect to the linked information, a plurality of pieces of link information are prepared, for example, for some variations by region or contract,
Among them, it is different in that the terminal device side provides a suitable product.

That is, in the broadcast data D1 received by the antenna 51, the information corresponding to the file name is the same, but, for example, the unique information of various regions is added. Then, when the user selects, for example, “art exhibition” displayed on the display 55 with a touch panel function, the link information analysis circuit 53 causes the terminal device installed in Tokyo to display “chl / abcd / shop
"/Art.htl/tokyo" is displayed as "chl / abcd / shop / ar" as the data to be displayed next on the terminal device installed in Saitama prefecture.
"t.htl / saitama" from the link information in the received data D2, and outputs the search result to the display circuit 54 for display on the display 55 with a touch panel function.

In this way, even if the same and the same "shopping document data" are broadcast, an appropriate display is made by the receiving terminal device, which is not only easy for the user to use, but also the program provider can individually There is no need to prepare data.

Therefore, according to the eleventh embodiment, the information corresponding to the file name has the same content, and the information for the part peculiar to each terminal device (for example, specific area, contract type, terminal use, etc.). By broadcasting multiple files with variations, when displaying characters such as documents based on instructions from the user, the linked information becomes the area information and contract type content held by the terminal device. The link information analysis circuit 53 determines whether or not they are compatible.
Then, a suitable document can be displayed on the screen of the display 55 with a touch panel function. Also,
In the eleventh embodiment, since it is sufficient to send one document data having the same link information to all terminal devices, it is possible to manage and reduce the amount of transmission data.

In the seventh to eleventh embodiments, shopping information and event information are explained.
It is also possible to perform program information that informs the user of information such as program broadcast time and pay broadcasting.
