It becomes possible to provide a certain program.

<Operation> The operation of the content display of the data receiving device 121 in the above-described digital broadcasting system and the data constituting the content will be described below with reference to the drawings. FIG. 34 is a diagram illustrating an example of a screen displayed by the data receiving device in the digital broadcasting system described above.

FIG. 3 shows a screen relating to a mail order program. A content 210 indicating a menu of mail-order sales, a content 220 indicating video product introduction, and a content 230 indicating stereo product introduction are shown. The display of the plurality of contents 210, 220, and 230 is switched by the user's operation as indicated by arrows 240, 241, 242, and 243.

When the user selects and determines the "video" button 211 while the content 210 indicating the menu of the mail order is displayed on the display screen, as shown by an arrow 240, the display screen is displayed. , The display is switched from the content 210 to the content 220 indicating the video product introduction. Next, when the user determines and operates the “menu” button 221, the display screen is displayed as indicated by an arrow 241.
The display is switched from the content 220 to the display of the content 210.

Similarly, when the user selects and determines the "stereo" button 212 on the display screen of the content 210, the display screen is switched from the content 210 to the display of the content 230 as indicated by an arrow 243.
Further, in this state, the user presses the “menu” button 231
Is determined, the display screen is switched from the content 230 to the display state of the content 210 as indicated by an arrow 242. In order to switch the display in response to such a user's interactive operation, the contents 210, 22
0 and 230 have buttons 211, 212, 221 and 231.

In order to realize the display switching by the interactive operation as described above, data constituting each content is transmitted from the data transmitting apparatus 101. FIG. 35 is a schematic diagram schematically showing data transmitted from the data transmission device side. The data 201 to be transmitted is composed of data indicating a plurality of contents, and the whole is repeatedly transmitted for a certain period. The reason for the repeated transmission is that when the user attempts to display an arbitrary content by an operation such as designating a link destination at an arbitrary time, data of the corresponding content can be obtained. In addition, since the content data is repeatedly transmitted as described above, it is needless to say that necessary content data can be obtained at any time even when the user attempts to start viewing the program from the middle of the program. No.

The data 201 to be transmitted is composed of a plurality of image data 215, 225, 235 and corresponding navigation information 216, 226, 236. Each of the image data 215, 225, and 235 is the content 21 described above displayed on the display screen of the data receiving device.
0, 220 and 230 are background images.

Each navigation information 216, 226, 2
Reference numeral 36 denotes a bitmap (Bitmap) indicating, for example, a button, which is on-screen display graphics superimposed on each of the image data 215, 225, and 235.
The data includes data, a script (Script) describing an operation process corresponding to a user's operation, and information of a hyperlink (Hyperlink) indicating a content of a link destination for switching display of the content. The information of the hyperlink includes an identifier of data such as an image constituting the content of the link destination and an identifier of navigation information.

The content 210 shown in FIG. 34 is represented by image data 215 and navigation information 216. Similarly, the content 220 includes image data 225
The content 230 is represented by image data 235 and navigation information 236.
Is represented by FIG. 36 is a diagram schematically illustrating a state of data transmitted from the data transmission device side.

The transmitting apparatus repeatedly transmits the data 201 at regular intervals. Although the image data and the navigation information are shown in a frame structure in this figure, actually, the digitalized image data and the corresponding navigation information are multiplexed, and the data 201 is transmitted as an MPEG2 transport stream. I do.

Hereinafter, data multiplexed and transmitted from the data transmitting apparatus 101 will be described in detail. FIG.
FIG. 3 is a diagram showing a state of multiplexing of data transmitted from the data transmission device side. The data transmitted as exemplified in the figure includes image data VE (N), navigation information table NE (N), and stream correspondence table V
System information such as ET (N), PCR, and PAT and PMT are multiplexed.

Here, an arrow 202 in the figure indicates a range corresponding to the repeatedly transmitted data 201 shown in FIG. In the example shown in the figure, 63 contents are multiplexed, and the image data VE (0) to VE (62) include P
“0x0084” is given as the ID and str
“0xe0” to “0xef” are cyclically given and multiplexed as the beam_id.

The stream correspondence information VET (N) is given “0 × 0083” as a PID.
The same value as VE_id, which is an image data identifier, is given as table_id_extension. The stream correspondence information VET (N) is the image data V
It is multiplexed once every E (N). The 63 pieces of navigation information NE (0) to NE (62) are PID
“0x0082” is given as
The value of NE_id which is the identifier of the navigation element is given as _id_extension and multiplexed. In addition, PCR, PAT, and PMT are also specified P
It is multiplexed given an ID.

Here, table_id_extens
“ion” and “stream_id” are identifiers for identifying each data by combining with the PID. Thereby, the data receiving device 121 stores these identifiers from the received data in the filter condition storage unit 131.
By setting to, it is possible to separate and extract desired data from the transmitted transport stream by the TS decoder unit 123.

Therefore, in order to form a hyperlink in response to a user operation or the like, the hyperlink information in the navigation information corresponding to the displayed content includes, for example, VE_id which is an identifier of the image data and the information of the navigation information. Since the identifier NE_id is described, the data constituting the content to be newly displayed can be separated and extracted based on this information to display the content.

This procedure will be described below. First, the data receiving device 121 acquires the PAT of the transponder (satellite repeater) currently being received. When the program selected by the user is another transponder, the data receiving apparatus 121 controls the receiving unit 122 by acquiring and referring to the NIT to change the transponder to receive. The description of is omitted.

Since the PAT has a PID set to 0 in advance, the data receiving device 121 can separate and extract the PID by setting PID = 0 in the filter condition storage unit 131. The PAT contains the PID of the PMT. Therefore, by acquiring the PID of the PMT corresponding to the program to be used and setting the PID in the filter condition storage unit 131, the PMT can be separated and extracted.

The PMT contains a PI for the component.
Since D is described, the data receiving apparatus 121 acquires the PID of the stream correspondence table VET, and converts the VE_id obtained from the information of the hyperlink into the table_
By setting the filter condition storage unit 131 together with the id_extension, the VET corresponding to the target image data can be separated and extracted.

Although VET describes component_tag and stream_id, the data receiving device 121 determines the PM based on the component_tag.
By obtaining the PID for the component with reference to T and setting the PID and the stream_id in the filter condition storage unit 131, the target image data can be displayed.

The data receiving device 121 is provided with the PID of the component in which the navigation information is multiplexed.
Is obtained by referring to the PMT, and the NE_id obtained from the hyperlink information is obtained from the table_id_exte
By setting in the filter condition storage unit 131 together with nsion, target navigation information can be separated and extracted.

Thus, the data receiving device 121 can obtain the image data and the navigation information that constitute the new content. Here, the data structure of the navigation information will be described in detail by taking the navigation information 216 simplified in FIG. 35 as an example. FIG.
9 is a diagram showing a data structure of navigation information 216. FIG.

[0050] The navigation information 216 includes
mode_Part301 and Handler_Part3
02 and Graphics_Property_Part
303 and Bitmap_Information_Pa
rt304 and Hyperlink_Informati
on_Part 305. Bytecode_P
The art 301 corresponds to a portion that is simplified as Script in FIG. 35, and is a portion in which bytecode, which is a kind of so-called script, is described. The bytecode includes various instruction sets related to control of image and audio data, in addition to an instruction set that enables basic programming such as conditional branching, integer operation, and access to constant variables.

In the example of FIG. 38, the bytecode of the 0th is P
usL0 and GotoPage. Pu
shL0 is an instruction for storing a value of 0 in the stack, and GoPage is an instruction for switching the display to the content of the link number indicated by the value stored in the stack. Here, the link number is H
hyperlink_Information_Part
Is an identifier for identifying the content to be switched.

Therefore, the 0th byte code describes the operation of switching the display to the content to which the link number 0 is linked. Similarly, the first bytecode describes the operation of switching the display to the content to which the link number 1 is linked. Handler
_Part 302 is a part describing the correspondence between the handler number and the bytecode number. In the example of FIG. 38,
Byte code numbers 0 and 1 are associated with handler numbers 0 and 1 respectively. Actually, not only the bytecode corresponds to the handler, but also information defining an environment for executing the handler process such as a variable area.

Bitmap_Information_
Part 304 is a part for describing the content of the bitmap to be displayed on the button corresponding to the graphics number. In the example of FIG. 38, a bitmap in which “video” is drawn is associated with the graphics No. 0, and a bitmap in which “stereo” is drawn is associated with the graphics No. 1.

Graphics_Property_P
The art 303 is information configuring on-screen display graphics superimposed and displayed on the display screen with image data, and includes graphics numbers for identifying graphics, graphics types and coordinates to be displayed, and graphics. It contains the number of the corresponding handler and a value indicating the initial state when the content is displayed. In the example of FIG. 38, the graphics type is a button, the graphics number is a value of 0 or 1, and the aforementioned Bitmap
_Information_Part 304 corresponds to the graphics number included in the _Information_Part 304. Hereinafter, the button with the graphics number n is referred to as “button n” or “n-th button”. The set of x coordinate and y coordinate for displaying button 0 and button 1 respectively is (20, 20), (20, 6).
0). The numbers of the handlers to be activated when the buttons 0 and 1 are selected and confirmed are 0 and 1, respectively. Also, 0 in the initial state in which the content is displayed.
The initial state of the numbered and numbered buttons is visible.

Hyperlink_Informati
The on_Part 305 is a part in which the ID of a material constituting the content of the link destination is described. A material ID is described as information indicating all contents to be switched from the content having the navigation information as an element. A link number is added as an identifier for collectively identifying each content to be switched to. In the example of FIG. 38, NE_i is set as the 0th link destination.
d = 1, VE_id = 1, and the ID of the NE
Indicates that the content is a link destination based on the information of the first content and the VE having the first ID. The first link destination is a content configured based on the information of the NE having the second ID and the video element having the second ID.

The fact that NE_id is 0 in the upper part of FIG. 38 means that the navigation information described here is a navigation element having an ID of 0. Therefore, the data receiving device 121
Displays the button “video” and the button “stereo” of the content 210 shown in FIG. When the button is selected by the user, control of switching to another content is performed.

That is, when displaying the content, the reception control unit 126 sets the Graphics_Property
With reference to y_Part, the graphics number is displayed in a predetermined display state at predetermined coordinates in order from the graphics with the number 0, and in response to the operation of button selection confirmation by the user, the handler number described in Graphics_Property_Part is displayed. Execute the corresponding handler process. The handler process is associated with the handler number with reference to the Handler_Part and the Bytecode_Pa
This is performed by executing the bytecode described in rt. The execution of the bytecode is interpreted and executed one instruction at a time by a bytecode interpreter (not shown) in the reception control unit 126.

As described above, in this digital broadcasting system, image data, navigation information, and the like, which are data necessary for displaying contents, are multiplexed and repeatedly transmitted from the data transmitting device side, and are received. In such a data receiving apparatus, content display can be performed by separating and extracting necessary information from transmitted data in response to a user's selection operation. That is, an interactive service can be realized by a one-way broadcasting system.

[0059]

By the way, in an actual broadcast, a program having the same contents may be re-broadcasted at a later date. However, in order to save labor, various data constituting a program once produced are completely reproduced as they are. There is a request to use it. The points to be considered in satisfying this request are, for example, when broadcasting content including image data drawn as “Until September 10, 1996 during the campaign period”, until September 10, 1996. To be displayed as it is, but if it is to be rebroadcasted after September 11, 1996, it is inappropriate to display it as it is.
There is a possibility that there is data that should not be displayed at the time of rebroadcasting. To satisfy this request, the link destination is controlled according to the broadcast date and time to prohibit the link to the data at the time of rebroadcasting A mechanism is required.

In an actual broadcast, it is usual to broadcast a plurality of programs that are different for each time. In this case,
There is a demand to dynamically link links due to differences in program broadcast time in order to establish links between programs. In order to satisfy this demand, a mechanism for controlling the link destination according to the end date and time of the program to be linked is required. further,
From the viewpoint of broadcasting a variety of program contents, a mechanism for changing the contents to be displayed when a predetermined time has elapsed after a user's operation or the like or restricting functions that can be operated by the user is also required.

The bytecode interpreter 1051 has a stack area for storing variables. In this case,
First, PushL0 is interpreted and 0 is stored in the stack area. Next, a process of interpreting the GotoPage and switching to the content corresponding to the link number indicated by the value stored in the stack area is performed. After the activation of the handler (step S3130), the process returns to the process of determining whether or not the content has been switched (step S3020). Since the content has been switched, new content is displayed (step S30).

Will be switched to the content indicated by.

After the activation of the handler (step S3130), the process returns to step S3020 to determine whether or not the content has been switched. Since the content has been switched, the next content is displayed (step S3030). Here, the next content is the same as the initially displayed content, but displays the image data 2150 indicated by VE_id = 0 as a background and displays on-screen display graphics according to the content of the navigation element of NE_id = 0.

Therefore, if the time when the new content is displayed is 14: 59: 00: 00 on September 9, 1996, a display screen as shown in a screen transition 3230 is displayed. After displaying the content, NE's Time_Even shown in FIG.
In t_Part 2161, the second handler is set in 1996.
In this case, the date and time designation flag is set to 1 (step S3050) because the description is made to start at 15: 00: 00: 00 on September 9, year.

If the date and time designation flag is 1 (step S3070), the current date and time are acquired (step S308).

ility, PushL1, PushL0, SetGr
The bytecode sequence “aphicVisibility” is executed by the bytecode interpreter 1051.

The bytecode interpreter 1051 first interprets PushL2, stores 2 in the stack,
Interpret hL1 and store 1 in the stack. Next, SetG
This instruction is to interpret graphicsVisibility and fetch the first variable, which is another indication of visible / invisible, and the second variable, which is the graphics number of the visual control target, from the stack to control the visualization of graphics. As a first variable, 1 indicating visibility is extracted from the stack, and as a second variable, a graphics number 2 is extracted from the stack, and the second graphics is made visible.

Thereafter, similarly, PushL0, PushL
0, SetGraphicVisibility is sequentially interpreted and executed to make the 0th graphics invisible, and PushL1, PushL0, SetG
The first graphics is rendered invisible by sequentially interpreting and executing the command as "graphicVisibility".

Accordingly, the reception control unit 1050 makes the button “Acceptance has been closed” visible via the bytecode interpreter 1051, and displays “Video”
Is rendered invisible, and as a result, a display screen as shown in a screen transition 3240 is displayed. In this way, the data presentation control device 1000 executes the processing of the specific handler at the designated date and time.

<Acquisition of Current Date and Time and Time Difference Correction> The acquisition of the current date and time and time difference correction in the data presentation control device 1000 will be described in detail below. The current date and time are obtained from the TDT stored in the time information storage unit, and the time difference is obtained from the TOT. FIGS. 10A and 10B are diagrams showing the data structures of TDT and TOT, respectively.

In the figure, an example of contents is shown in parentheses. The TDT is a table holding data of the current date and time. As shown in FIG.
The format is month, day, hour, minute, and second. In this example, TDT is described as 14: 57: 0 on September 9, 1996, indicating that the time at which this TDT was transmitted is this time. The actual data is stored in the BCD code.

The TOT describes a plurality of sets of the current date and time, a country code and a time difference. Here, the country code is a code predetermined by the country. The country code is also fixedly stored in the data presentation control device 1000. Also, the time difference is + or-
Expressed in minutes and seconds. In this example, the time difference in the UK is 0, and the time difference in Japan is +9 hours. Therefore, the value of the time difference corresponding to the country code that matches the country code stored inside the data presentation control device 1000 can be acquired and used for time difference correction.

[0135] These TDT and TOT have PIDs defined in advance, and are sequentially transmitted from the data transmitting device side as time progresses. Therefore, the data presentation control device 1000 sets the reception unit 1010 and the TS decoder unit 1021 by setting a predetermined PID in the filter condition storage unit 1021 when the current date and time are required.
0, and can be stored in the time information storage unit 1044 inside the reception data storage unit 1040 and can be used.

The reception control unit 1050 performs the processing in step S3
At step 080, the TDT and TOT are obtained, and the process proceeds to step S309.
At 0, the time is converted to the current time in the country where the data presentation control device is installed by referring to a country code fixedly stored in advance inside the data presentation control device 1000. The reception control unit 1050 determines in step S3100 that the NE
The current time is compared with the date and time specified by Time_Event_Part. In the first embodiment, Time_E
The date and time described in the vent_Part is defined based on the time in the country where the data presentation control device is installed. Regardless of how the reference time is determined, by performing the time difference correction when comparing the reference time with the current time, the handler can be correctly started at a predetermined date and time. Here, the time difference in the time difference correction is the current date and time and Time_Event_P
The difference between the date and time described in the "art" and the reference time used as a reference.

As described above, according to the data presentation control device of the present invention, the handler can be activated by designating the date and time, and the handler is realized by a bytecode sequence including an instruction set for executing various operations. Therefore, it is possible to switch the content, change the display state of the buttons, and perform other operations at the designated date and time. <Second Embodiment> Hereinafter, as a second embodiment of the present invention, a data presentation control device that receives a digital broadcast and has a mechanism that changes an operation corresponding to a user operation according to date and time will be described. explain.

[0138] The data transmitting apparatus for transmitting a digital broadcast according to the second embodiment is different from the first embodiment only in the content of the navigation information to be transmitted, and therefore the description is omitted. The contents of the navigation information will be described below when describing the data presentation control device. The data presentation control device according to the present invention in the second embodiment determines the validity period of the handler so that the activation of the handler based on the operation of the user can be performed.
It has a feature of activating an optimum handler according to the operated date and time, and is an extension of the function of the data presentation control device in the first embodiment.

The structure of 70, 2370 is the same as the navigation information 21 described above.
Same as 70.

<Operation of Reception Control Unit 1050> The operation of reception control unit 1050 in data presentation control device 1000 having the above configuration will be described below with reference to the drawings. The second embodiment is similar to the first embodiment in FIGS.
This will be described based on the contents 2100, 2200, and 2300 shown in FIG. However, the navigation information 2160, 2260, and 2360 in FIG. 3 are replaced with navigation information 2170, 2270, and 2370, respectively, and therefore, the transition between the contents in FIG. 2 is slightly different.

[0146] The reception control unit 1050 is constituted by a CPU and a program, and performs processing of content switching operation and handler activation operation. Basic operation is the first embodiment
(See FIG. 8), and the only difference is the handler activation process (S3130). The handler activation process will be described in detail below. FIG. 14 is a flowchart illustrating the operation of the activation process of the handler according to the second embodiment.

The handler activation processing includes processing groups S 3131 and S 3132 for acquiring the current date and time, and a processing group S 3133 for performing validity determination and execution for each sub-handler which is a unit having a valid period for the activated handler. S31
34, S3135, S3136, and S3137. Currently, 14:58, 0 September 9, 1996
Secondly, the description will be made on the assumption that the user has selected the button marked “video” while the content 2100 is being displayed.

The processing for starting the handler starts with the acquisition of the current date and time (step S3131). Reception control unit 10
50 obtains the TDT and TOT from the time information storage unit 1044, obtains the current standard date and time, and corrects the time difference in the country where the data presentation control device 1000 is installed (step S3132). The processing of obtaining the current date and time and correcting the time difference are the same as those described in the first embodiment. As a result, 14:58 0 September 9, 1996
Seconds are obtained.

After obtaining the current date and time and correcting the time difference, the reception control unit 1050 focuses on one sub-handler of the designated handler (step S3133) and determines whether the current date and time is within the valid period (step S3134). ).
The handler specified here refers to one handler determined based on a user's button selection operation, or a specific handler activated by specifying the date and time described in the first embodiment.

In the example shown in FIG. 11, when the button “Video” is selected, the No. 0 handler is activated. (Step S3133), the validity period is September 9, 1996.
Since it is valid up to 14:59:59 on the day (step S3134), the bytecode corresponding to the sub-handler is executed (step S3135). Therefore, the 0th bytecode corresponding to the 0th subhandler is executed.

As shown in Bytecode_Part 2172, the 0th byte code is PushL0, GotoP
age is described, Hyperlink_In
The contents of NE_id = 1 and VE_id = 1 described in the formation_Part 2176 are displayed. After completing the process of the 0th sub-handler, the reception control unit 1050 determines whether there is a next sub-handler (step S3136). Since there is a 2nd sub-handler, paying attention to this 2nd sub-handler (Step S313
7) It is determined whether the current date and time is within the validity period (step S).
3134), execution is skipped because it is out of the validity period,
Since there is no next sub-handler, the process of starting the handler ends.

This screen transition state will be described with reference to FIG. FIG. 15 is a diagram illustrating transition of a display screen according to the second embodiment. The screen transition 3310 is a diagram showing the transition of the screen at 14:58:00 on September 9, 1996. "Video" by user from content 2100
A state in which the display is switched to the content 2200 by selecting a button is shown.

After that, the content 220 is
When the button drawn as “Menu” of 0 is selected, the handler of No. 0 of the Handler_Part of the navigation information 2270 corresponding to the content 2200 corresponds to the sub-handler of No. 0 having no validity period restriction. Since the 0th bytecode corresponds to the 0th subhandler, the 0th bytecode is executed, and as a result, the content 2100 is displayed.

After that, the time passed, and
It is assumed that it is 15: 1: 00: 00 on the 9th of the month. In this state, the process of activating the handler when the button “Video” is selected by the user is as follows.
First, the reception control unit 1050 acquires the current date and time (step S3131), and corrects the time difference (step S313).
2). As a result, 15:01:09 on September 9, 1996
Seconds are obtained.

After obtaining the current date and time and correcting the time difference, the reception control unit 1050 focuses on one sub-handler of the designated handler (step S3133) and determines whether the current date and time is within the valid period (step S3134). ).
In the example of FIG. 11, when the button drawn as “video” is selected, the 0th handler is activated, and the 0th handler shown in the Handler_Part 2173 is focused on the 0th sub-handler (step S3133), validity period is 14:05 on September 9, 1996
It is invalid because it is up to 9 minutes and 59 seconds (step S313
4) The execution is skipped, and the next second sub-handler is focused (steps S3136 and S3137). Since the validity period is 15: 00: 00: 00 on September 9, 1996, it is valid (step S3134). Execute the bytecode corresponding to the second sub-handler (step S31)
35).

As shown in Bytecode_Part 2172, the second byte code is PushL2, PushL2

Since it is described as GraphicVisibility, similarly to the first embodiment, the button drawn as “acceptance has been closed” is made visible, and the button drawn as “video” and the button drawn as “stereo” are displayed. Is made invisible.

After the execution of the bytecode, there is no more sub-handler (step S3136), and the processing for starting the handler ends. Therefore, the screen transition 3320 in FIG.
The display is switched from the content 2100 to the content 2400 when the user selects the “video” button as shown in FIG.

As described above, the data presentation control device 1000 according to the present invention in the second embodiment operates differently according to the date and time by handling the navigation information having the data structure in which the information of the valid period is added to the handler. Can be. <Third Embodiment> Hereinafter, a third embodiment of the present invention is a data presentation control device for receiving a digital broadcast, which performs a specific operation only when a predetermined graphics is displayed at a specific date and time.

The initial state of the numbered button is visible.

[0203] Hyperlink_Informati
The on_Part 8166 is a part in which the ID of the material constituting the content of the link destination is described, and a link number is added as an identifier for identifying each content collectively. In the example of FIG. 25, VE_id = 1 is described as the 0th link destination, and VE_id
Indicates that one content composed of the first image data is a link destination, and the first link destination is V
E_id is the content composed of the second image data, and the second link destination is that the VE_id is the content composed of the third image data.

The fact that NE_id is 0 in the upper part of FIG. 25 means that the navigation information described here is a navigation element having an ID of 0. The navigation information with NE_id = 0 constitutes one content together with the image data displaying the quiz with VE_id = 0.

[0205] Based on these data, the data presentation control device 1000 displays another content on the screen when the user selects a button or the like for the displayed content. Tim
Control such that a specific operation is executed after the time described in e_Event_Part elapses can be realized.

<Operation of Data Presentation Control Apparatus> The operation of reception control section 1050 in data presentation control apparatus 1000 will be described below with reference to the drawings based on the above data structure. FIG. 26 is a flowchart showing the content switching operation and the handler activation operation.
7 (a) and FIG. 27 (b) are diagrams showing transitions of the display screen when the user answers the quiz in time and when the user does not answer in the time.

The processing control of the reception control unit 1050 includes an initial processing S8510 for specifying the content to be displayed first at the start of the program reception, and a processing group that operates only when the determination processing S8520 determines that the content has been switched. S8530, S8540, S8550, S8
560, processing groups S8580 and S8590 that operate when it is determined by the determination processing S8570 that there is a handler to be activated by specifying the date and time, processing groups S8600 and S8610 corresponding to user input, and handler activation. This is realized from step S8620.

Information on the first content is stored in the PMT stored in system information storage section 1043 in VE_i.
It is defined as a set of d and NE_id. Here, the following operation will be described assuming that VE_id = 0 and NE_id = 0 are described in the PMT. First, VE_id = 0 and NE_id = 0 are acquired from the PMT as information of content displayed first in the quiz program (step S8510).

Since the content is the first content, it is treated as switched (step S8520), and the content is displayed (step S8530). The content is displayed by displaying image data 8150 indicated by VE_id = 0 as a background and displaying on-screen display graphics according to the contents of the navigation element of NE_id = 0. NE Graphi shown in FIG.
cs_Property_Part8164 and Bitm
According to the contents described in ap_Information_Part 8165, a button drawn as “apple” is displayed at coordinates (20, 20) in a visible state, and a button drawn as “Mikan” is displayed at coordinates (20, 60) in a visible state. I do.

Accordingly, a display screen as shown in screen transition 8910 is displayed. NE's T after displaying content
If the description that activates the handler by specifying the elapsed time from the start of the display of the content is made in the image_Event_Part (step S8540), the time specification flag is set to 1 to perform the handler activation process based on the elapsed time (step S8550). If there is no description of the elapsed time designation, the time designation flag is set to 0 (step S8).
560). NE Time_Event_ shown in FIG. 25
Since the Part describes that the second handler is activated when 10 seconds have elapsed from the start of the display of the content, the time designation flag is set to 1 in this case (step S8550).

If the time designation flag is 1 (step S8570), the elapsed time from the start of the display of the content is counted (step S8580), and the elapsed time is set to N
It is determined whether or not the time specified by Time_Event_Part 8161 of E has come (step S85).
90) If the specified time has not been reached, the process moves to a process of moving the selection pointer in accordance with the user's input (step S8600). If any button is selected (step S8610), the handler is activated. Is performed (step S8620).

[0212] Here, first, an example in which the user answers the answer within 5 seconds from the start of the display of the content displaying the quiz will be described. Since 10 seconds have not yet elapsed (steps S8580 and S8590), the process moves to a process of moving the selection pointer in accordance with the user's input (step S860).

If the user selects the button labeled “apple” (step S8610), Graphics_Pro
The handler of No. 0 is started with reference to the party_Part 8164 (step S8620). 0
The handler process of number 0 is configured by byte code 0, and the content of byte code 0 is PushL0,
Since it is a GotoPage, Hyperlink_I
The content is switched to the content indicated by VE_id = 1 which is the link destination of No. 0 described in ninformation_Part 8166. Note that the reception control unit 1050 executes the bytecode using the bytecode interpreter 1051.

After the activation of the handler (step S8620), the process returns to the process of judging whether or not the content has been switched (step S8520). Since the content has been switched, new content is displayed (step S8530). The display screen at this time is an image indicating that the answer is correct, as shown in screen transition 8920.

[0214] Next, a case will be described as an example where the user has not been able to answer the question even after 10 seconds have elapsed from the start of the display of the content displaying the quiz. At first, screen transition 893
It is assumed that the screen shown at 0 is displayed. When 10 seconds have elapsed from the start of the display of the content (step S858)
0, S8590), the second hand is activated (step S8620). The second handler process is configured by the second bytecode. Since the content of the second bytecode is PushL2 and GotoPage, H
hyperlink_Information_Part
VE_id which is the second link destination described in 8166
= 3.

After the activation of the handler (step S8620), the process returns to the process of judging whether the content has been switched (step S8520). Since the content has been switched, new content is displayed (step S8530). Thus, an image indicating that the time has expired is displayed as shown in screen transition 8940.

Thus, the data presentation control device 10
00 executes processing of a specific handler when a predetermined time has elapsed from the start of content display.
