Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmission / reception system, and more particularly to a method for storing data distributed by a broadcasting system and a communication system by a receiving terminal.

[0002]

2. Description of the Related Art As a conventional invention relating to storage-type data, there is a music data distribution system described in Japanese Patent Application Laid-Open No. H11-213639. In this system, for example, when a user watching a music program inputs a request for music data reception to a receiving terminal using an input device such as a remote controller, music data desired by the user is transmitted from the center and received. It can be received by the terminal and stored in an external storage medium.

Similarly, storage of data using data broadcasting by digital broadcasting can be considered.

[0004] The data broadcast described here is multiplexed with a program together with a program and transmitted.
Broadcast of program additional information that can be displayed on a screen by a user in conjunction with a program or executed by a receiving terminal. The program additional information using data broadcasting is prepared by the center as descriptive data (hereinafter referred to as descriptive data) described according to a multimedia content description format.

[0005] Here, as an example of the conventional techniques, a specific description example of descriptive data by data broadcasting and a simple operation example of program additional information which can be actually obtained by a user according to the description content are shown in FIG. (A), (c), FIG.
This will be described with reference to FIG.

FIG. 3 shows a description example of description type data.

FIG. 4 is an actual screen display image based on the data described in FIG.

[0008] The descriptive data of (a) and (c) of FIG. 3 are interpreted in the receiving terminal, and the images of screen 1 and screen 2 of FIG. 4 (a) are displayed, respectively.

Hereinafter, description contents of FIGS. 3 (a) and 3 (c)
A specific operation example based on the description will be described.

A character string enclosed by <info></info> is shown in FIG.
(a) and (c) are module names for identifying each other's data.

For example, when designating the data of FIGS. 3A to 3C, the module name "1" of FIG. 3C is designated as, for example, goto module "1".

A character string enclosed by <graphic></graphic> describes an image file displayed by the data. In FIG. 3A, button. bmp.
This is a button image like screen 1 in FIG.
ton. bmp is displayed on the display device.

[0013] In a region surrounded by <script></script>, processing content to be executed by the receiving terminal is described. <bevent push
button = 1> waits for one button input from the remote control, and when it is input, triggers it,
<script> This is a description for activating the processing described below.

FIG. 3A, which is descriptive data described based on such rules, is interpreted by the receiving terminal, and FIG.
When a user inputs data from a remote controller or the like to the receiving terminal while displaying the screen 1 in FIG. 4A, the display content is changed to the data described in FIG. The screen 2 of (a) is displayed.

[0015] By using the descriptive data of the data broadcast, data such as a still image distributed by the center can be presented on a display device, processing can be executed in a receiving terminal, and data can be saved. it can.

[0016]

However, the storage of the descriptive data of the program additional information by music data or data broadcasting is only to receive and store the data uniquely determined and transmitted by the center in advance. You cannot receive different data from other users.

In the case of distributing a plurality of data by the conventional techniques, the center needs to distribute descriptive data such as those shown in FIGS. 3B, 3C and 3D and respective images.

Here, the description contents of FIG. 3B will be described.
Basically, it is based on the same description rule as that of FIG. 3A, but the processing content described in a part surrounded by <script></script> is more complicated than that of FIG. Has become.

In FIG. 3B, rnd (), which is a process for generating a random number, is executed when an input from a remote controller or the like is input to the receiving terminal. As a result of the processing, the generated random number is divided by 2, and the remainder is described in result.
If result is 0, module1 is executed, and if result is 1, module2 is executed. Here, when the result is 0, the display content transits to FIG. 3B, and FIG.
Write_me, which is a process of displaying an image of the sun as in screen 2 of FIG.
The memory. () process is executed, and sun. Save the bmp to a storage medium. Similarly, if the result is 1, FIG.
The display content changes, and after displaying an image of the moon as shown in a screen 3 in FIG. 4B, moon. Save the bmp.

As described above, in order to be able to receive different data for each user by the conventional technology,
The center has to prepare all the different data, and describe and transmit the descriptive data so that different data can be received for each receiving terminal.

However, in such a method, for example, when transmitting a game character that can be used in a game machine by using data broadcasting, each user can only obtain exactly the same character data.
Lack of entertainment makes it difficult to provide new services that users demand.

According to the present invention, characteristic data including undetermined parameter values distributed by a broadcast system or a communication system is determined by a parameter determination process or user-specific profile information in a receiving terminal, and is stored in a storage medium. An object of the present invention is to realize a method for storing data, in which data transmitted at a time is unique, but different data can be received for each user.

[0023]

In this embodiment, the interpretation and execution of data are performed by the reception control unit 260 shown in FIG.

[Acquisition of Data] In the following, a processing block will be described for the procedure of executing data accumulation by using the descriptive data of a data broadcast as a trigger as soon as a user inputs to a receiving terminal. This will be described with reference to FIG. 5 which is a diagram, FIG. 6 which is a flowchart, and FIG. 7 which is a description type data example.

The data acquisition process 510 in FIG. 5 is executed by an input to the receiving terminal by the user, and determines the undetermined data 552 including the undetermined parameters, which is distributed from the transport stream, and the parameters. Parameter determination processing 551 in which the processing for this is described is obtained and stored in the reception data storage unit 550.

The undetermined parameter determination execution processing 520 is as follows.
The processing content described in the undetermined parameter determination processing 551 stored in the reception data storage unit 550 is stored in the undetermined data 55

[Determination of Undetermined Data Parameter] Here, the undetermined data will be described as character data of the game.

FIG. 8 shows a configuration image of the undecided data 552 in FIG. 5, and FIG. 9 shows specific undecided data.

In FIG. 8, character data 810
Is an undetermined parameter 81 for which a specific numerical value has not been determined

For character data 810, a process 801 for determining which of a plurality of image data 811 is to be washed and a process 802 for determining a numerical value for which the undetermined parameter 812 has not been determined are referred to as undetermined parameters. The confirmation process is executed, and the confirmed character data 820
Generate

FIG. 9 is a specific data configuration example of undecided character data.

The undecided character data has IMAGE 1, 2, and 3 as image data, and these image data are uniquely determined by the total value. The correspondence between the total value and the image data is provided as a table to the undetermined character data. In addition, parameters such as the intellect and physical strength, including the total value, are not specifically determined, and are blank. The determination method for determining the range and initial value of these data, and specifically the numerical value is also determined as Randam or average, and is held as a table in the undetermined character data. Data such as character names and special skills are uniquely determined.

FIG. 12 is a diagram showing the internal structure of the undetermined parameter determination processing. The determination method in FIG. 9 is associated with this table, and the processing corresponding to the specified data determination method is extracted and executed.

As will be described later, the argument passed to the corresponding process may be placed in the receiving terminal in advance as profile data.

First, the undetermined parameter determination execution processing 520 in FIG.
The undetermined parameter determination processing 551 is executed (the description type data for executing the undetermined parameter determination processing 551 in FIG. 5 corresponds to (2) in FIG. 7).

In the undecided data 552 in FIG. 5, data corresponding to each parameter is not decided as shown in FIG. The determination method is determined for each parameter, and the index name is described in the undetermined data as shown in FIG. For example, Random, which internally generates random numbers, average, which takes an average value, and prof, which determines an undecided parameter using the personal profile information input by the user from the data broadcast screen as an argument
ile is conceivable. The undetermined parameter determination processing 551 checks which processing is to be executed based on the undetermined data 552 (equivalent to 640 in FIG. 6B). The processing itself corresponding to the index name is described in the undetermined parameter determination processing 551. The undetermined parameter determination process is represented by a table as shown in FIG. 12, and the process of the index name is executed.

[Writing to External Storage Medium] When the undetermined parameters are determined, the undetermined character data in FIG. 9 becomes the determined character data as shown in FIG.

In FIG. 10, one of the plurality of image data IMAGE1, IMAGE2, IMAGE3 prepared in FIG. 9 is selected, and the blank parameter data is also specifically determined. (A) is an example of a relatively excellent character, and (b) is an example of a slightly inferior character.

The received data is stored in the received data storage unit 550 as the decision data 553 in FIG. Thereafter, the storage medium recording process 530 in FIG. 5 writes data to the external storage medium 560.

[Use of Character Data by Digital Apparatus in Game Machine] Reading of character data stored in a storage medium by a game machine is performed by moving data from an external storage medium. FIG. 11 shows an example of a screen in which a game is played using the actually received game character.

As described above, according to this embodiment, data having undetermined parameters can be determined and stored in the receiving terminal. Also, different data can be obtained for each user even if the data to be distributed is the same.

The algorithm for determining the parameter value of data having an undetermined parameter is not limited to the random number generation method alone. For example, parameter values prepared in advance in the data may be randomly selected and set, or the parameter values may be increased or decreased in proportion to the program viewing time.

Note that there are a plurality of types of undecided data in one program, and a plurality of data can be obtained by a user's input. Even in such a case, the description in FIG. 7 can be realized by describing a plurality of data. At this time, a branching process may be prepared on the assumption that no module can be obtained.

In this embodiment, the determined data is stored in the storage medium 5 by the storage medium recording process 530 in FIG.
40, but this is not necessarily required,
Undecided data may only be output from the receiving terminal as determined data.

The description has been made on the assumption that the user obtains data by performing an input using the remote controller.
The input device is not limited to the remote controller, and may be a device provided by an input device such as a button prepared in the receiving terminal, a keyboard, and a mouse.

[0086] When the user receives data, a reception condition may be set such that the data can be received by viewing the data for a certain period of time. This will be described with reference to FIG.

FIG. 20 is a flowchart in the case where data can be acquired according to the viewing time.

In this case, it is assumed that the receiving terminal has an audience measurement process in the read-only data storage unit 300 in FIG. 2 in advance. The viewing measurement process is started when a specific program is selected by using a flag included in the stream as a trigger (21 and 22 in FIG. 20). If the value exceeds a certain value, the undecided data distributed by the data broadcasting can be obtained (2 in FIG. 20).
3, 24).

A flag indicating that storable data is included in the stream of the program is prepared. By using this flag, it is possible to start execution of the viewing measurement process on the receiving terminal side. The information that the user continues to watch can be determined based on whether or not the user is viewing a program with the same PID. While viewing a program with the same PID, the viewing measurement process performs an internal counting process.

Note that the viewing measurement processing is reset when the channel of the program is changed by the user. After the reset, the timer is executed again when the same program is selected again.

When the program ends, the viewing measurement process ends regardless of the value of the material measurement value.
In addition, data can be stored immediately when a program is switched. Further, in conjunction with this function, it is possible to realize gourmet coupon data of a restaurant in which the discount amount is determined in proportion to the program viewing time.

Note that the number of times of obtaining the distributed data can be limited to one time. In this case, when the data acquisition process reaches a certain number of times in the descriptive data, the data acquisition process is described so as not to be executed, and the actual acquisition process execution number is managed by the received data storage unit. It is possible.

In the present embodiment, an example has been described in which determined data is stored in an external storage medium, but storage in an external storage medium is not essential. The decision data may be directly transferred to another device, or may be stored in an internal storage medium in the receiving terminal.

In the present embodiment, a digital broadcast receiver is used as a receiving terminal. However, in general, the terminal does not have to have a boundary.

(Embodiment 2) In Embodiment 1, FIG.
As described above, the undetermined parameter determination processing for determining the undetermined parameter is transmitted together with the undetermined data. However, the undetermined parameter determination processing can be realized even if it is prepared in the receiving terminal in advance.

In this embodiment, a method of determining undetermined data when the undetermined parameter determination processing is provided in the receiving terminal will be described with reference to FIG.

When the undetermined parameter determination processing is prepared in the receiving terminal in advance, the configuration is as shown in FIG. This configuration is basically similar to the configuration in FIG. However, in FIG. 5, the undetermined parameter determination processing 551 distributed by the broadcasting system is extracted by the data acquisition processing 510 and is stored in the reception data storage unit 550, but in FIG. 560 is prepared in advance.

First, in FIG.
10 extracts only the undecided data 552 from the transport stream and stores it in the received data storage unit 550. Next, the undetermined parameter determination execution processing 520 executes the undetermined parameter determination processing 551 recorded in the read-only data storage unit 560 on the undetermined data 552.
The subsequent operation is the same as that of the first embodiment, and the decision data 553 in which the undecided parameters are decided is placed in the reception data storage unit 550 and recorded on the storage medium.

By using such a means, even if the undetermined parameter determination processing is not distributed by the transport stream, the undetermined data can be acquired and determined even if it is previously provided in the receiving terminal. become.

(Embodiment 3) In the first embodiment, a method for determining undetermined data having an undetermined parameter by using only the undetermined parameter determination processing has been described. A method for determining the undecided data using the user profile data input by the user as the auxiliary information with respect to is described.

Here, the profile data includes the name, ID, date of birth, blood type, weight, height, blood pressure, hobby, age, and how much the user is using the receiving terminal. And auxiliary information that can be used to determine the parameters of the data including the undetermined parameters. For example, FIG.
Is data managed in the receiving terminal as a table.

In this embodiment, by using the user's profile data input to the receiving terminal, an appropriate health index is calculated for the user, and cooking recipe data having an appropriate number of calories is generated for each user. Figure 1 for an example
This will be described with reference to FIG. 2, FIG. 14, FIG. 15, FIG.

FIG. 14 is a processing block diagram of acquiring data distributed by the broadcasting system, fixing undecided data, and storing the data in a storage medium. The flow of a series of processing is described in the above embodiment. This is the same as FIGS. 5 and 13 described above.

The difference from FIGS. 5 and 13 is that the user profile data 554 as auxiliary information for determining the uncertain parameter value of the undecided data 552 is stored in the received data storage unit.

FIG. 15 shows an example of undecided cooking recipe data.

The name of the dish is uniquely determined in advance.

The recipe includes image data A, B, and C corresponding to the recipes A, B, and C, respectively. These data are uniquely determined by the health value. The correspondence table between the health value and the recipe is included in the undecided cooking recipe data. Means for determining a health value is also described, but this is an index, and the specific processing to be performed is described in the undetermined parameter determination processing in FIG.

FIG. 16A shows an example of the determined recipe data. FIG. 16B is an image in which FIG. 16A is actually displayed on a screen.

FIG. 17 is a table of user profile data required in the undetermined parameter determination processing of FIG. For example, Pr in the data determination method of FIG.
In ofile # 1, the corresponding process includes the parameters Data1, 2, and 3. These parameters are shown in FIG.
The undetermined parameter determination process is shown in FIG.
The processing of Profile # 1 is performed using the specific numerical values defined in Step 7.

The user previously stores the user profile data 554 in the reception data storage unit 5 for the reception terminal.
50. The means can be realized by prompting the user to input data using the remote controller from the descriptive data described in the first embodiment. User profile data 55
As an example of No. 4, an image as shown in FIG. 17 is obtained. FIG.
7, Data1 and Dat are used as profile data names.
a2 and Data3, and corresponding data are prepared. In the present embodiment, these data indicate information such as the weight and height of the user. These specific numerical values are prepared as profile data and stored in a table.

Next, the undetermined parameter determination processing 551 in FIG. 14 reads the user profile data 554 and determines the undetermined parameter value of the undetermined data 552 based on the data. The image of the undecided data is as shown in FIG. For the dish name curry rice,
Three types of data of recipes A, B, and C are prepared.
As for the undecided cooking recipe data, any of the recipes A, B, and C is determined by determining the health value, and the determined cooking data as shown in FIG. 16A is generated. The means for determining the health value is Profile_2 in FIG. 15, and this processing is described in the undetermined parameter determination processing 551 in FIG. 14, as in the first and second embodiments. Specifically, the image is as shown in FIG. 12, and here, Profile__
2 is described.

The determination data 553 after the undetermined parameters are determined is stored in the reception data storage unit 5 as in the first and second embodiments.
50 is stored. Subsequent processing is the same as in the first embodiment. FIG. 16A shows the determined recipe data. The screen image actually output to the screen by the display device is as shown in FIG.

FIG. 6B is a flowchart showing the flow of these processes. If the user profile information exists in the branch at 660, the process proceeds to 670,
In the undecided data determination process, the user profile information is read out and used to determine undecided data.

In this way, by providing the profile data prepared by the user as auxiliary information to the processing for fixing the undecided data, various information is provided to the individual user based on the information of each individual. It is possible to do.

In the present embodiment, the recipe recipe data is described. However, in addition to the data including the undecided parameters received as “fortune-telling of the day”, the parameters are determined using the profile data of the user. For example, different fortune-telling data can be prepared for each individual.

Further, in the present embodiment, the method for storing user profile data 554 in received data storage section 550 and determining the undetermined parameters in FIG. 14 has been described. However, user profile data 554 is not information about the user but information about the user. Like the undecided data 552, the data transmitted by the broadcasting system may be the data of the decided parameter value itself. In this case, the undetermined parameter determination processing 551 only needs to simply read the user profile data (here, determined parameter values) and set the undetermined parameters of the undetermined data 552.

The undecided parameter determination processing 551 is transmitted by the broadcasting system as in the first and second embodiments, and the received data storage unit 55 is transmitted by the data acquisition processing.
May be set to zero.

(Embodiment 4) In Embodiments 1 and 2,
The module in the transport stream is extracted by describing the undetermined data to be obtained and the module address of the undetermined data determination processing in the description type data as shown in FIGS. 3 and 7, and then the undetermined parameters are determined. Although processing was performed, in the present embodiment, without using descriptive data, the user simply presses an input device such as a button provided on the receiving terminal to retrieve data from the transport stream, A method for performing a series of operations such as a determination process and a recording process will be described. 18 and 19 are used for the description.

FIG. 18 is a processing block diagram of an operation for extracting the undecided data from the transport stream, using the undecided parameter decision processing to convert the undecided data into decision data, and recording the decided data. The flow of the entire operation is the same as in the first, second, and third embodiments described above, which are the same as those in FIGS. 5, 13, and 14.

The difference is that the read-only data storage unit 5
60, an acquisition address 555 which is data for obtaining a module from a transport stream is prepared in advance.

FIG. 19 is a table in which addresses indicating where undetermined data and parameter determination processing exist in the transport stream are described, and are stored in the receiving terminal in advance. For example, when an input from a remote controller or the like is made by the user at the receiving terminal, the data acquisition processing checks the location of the data to be acquired from this table and extracts the data from the transport stream.

In FIG. 18, first, a data acquisition process 51
0 reads the acquired data address 555 from the read-only data storage unit 560. FIG. 19 shows an image of the acquired data address. In the data acquisition process, the acquired data address 555 is obtained from the transport stream.
The undecided data 552 designated by is extracted and stored in the received data storage unit 550. Here, the description will be made assuming that the undetermined parameter determination processing 551 is stored in the read-only data storage unit 560 in advance.
