And stored in the EPG area 35A. 24 hours after the current time (EPG2 and EPG1-
2) or after 150 hours (EPG2, EPG3
(In the case of EPG1-2 and EPG1-3), information on programs on each broadcast channel (for example, channels, broadcast time, titles, categories, etc., in addition to typical still images of programs). Since this EPG data is frequently transmitted, the latest EPG data can always be held in the EPG area 35A.

An EEPROM (Electrically Erasable Pr)
In an gramable read only memory (38), data to be retained even after the power is turned off (for example, the reception history of the tuner 21 for four weeks, the channel number (last channel) received immediately before some operation by the user is performed) ) Is stored. The data stored in the EEPROM 38 is, for example, when the power is turned on.
It is used for processing such as automatically receiving the same channel as the last channel again. If the last channel is not stored, the channel stored as the default in the ROM 37 is received.

When the sleep mode is set, the CPU 29 activates the minimum necessary circuits such as the front end 20, the demultiplexer 24, and the data buffer memory 35 even when the power is turned off, and performs reception. The current time is measured from the time information included in the signal, and control for causing each circuit to perform a predetermined operation at a predetermined time is also executed.
For example, timer automatic recording is executed in conjunction with an external VCR.

Further, the CPU 29 executes an OSD (On-Screen).
n Display) When it is desired to generate data, the MPEG video decoder 25 is controlled. MPEG video decoder 2
5 generates OSD data corresponding to this control, and
The data is written to, read from, and output from the RAM 25a. Thereby, predetermined characters, figures, and images (for example, characters, symbols, icons, and screens to be superimposed on a normal screen)
And the like can be output to the television receiver 3 and displayed. For example, as will be described later with reference to FIG. 9, various messages, voting items, marks (buttons), etc.
Displayed based on this OSD data.

The SRAM 36 is used as a work memory of the CPU 29. The modem 34 exchanges data via a telephone line under the control of the CPU 29.

FIG. 4 shows a configuration example of the remote commander 6. An IR signal transmitting section 72 for generating an IR signal corresponding to the operation of various keys is provided at an upper portion thereof.

The screen display key 79 is operated when switching on and off the display of characters and the like of the electronic program guide. The double sound key 80 is operated when a plurality of channels are present as sound channels and when these are switched.

The ten keys 81 are operated when inputting numbers from 0 to 9. The key of the number 0 and the key of “tuning” are operated when inputting the number 10 or 12, and the key arranged between them is operated when the number 11 is input.

The menu key 82 is operated when displaying a menu, and the promotion key 83 is operated when displaying a promotion channel. The program explanation key 84 is operated when displaying program explanation information in the electronic program guide. The multi key 85 is operated as an electronic program guide when a reduced screen of each broadcast channel is displayed in one screen as, for example, 4 × 4 multi screens. The program guide key 86 is operated when displaying the electronic program guide. The jump key 87 is operated when shifting to the last channel.

The up key 88, the down key 89, the left key 90, and the right key 91 (these keys are also referred to as direction keys as appropriate) are operated when the cursor is moved in the up, down, left, and right directions, respectively. Is operated when inputting the decision of selection. The channel up / down key 94 is operated to increment or decrement the channel to be received by one. The up key 88, the down key 89, the left key 90, the right key 91, and the enter key 92 are an up key 61, a down key 62, a left key 63, a right key 64, and an enter key provided on the main body of the IRD 2 shown in FIG. It corresponds to the key 65, and its arrangement is also made to correspond. The channel up / down key 94 corresponds to the channel up key 59 and the channel down key 60 in FIG.

The volume up / down key 93 is operated to increase or decrease the volume by a fixed amount.

Next, the basic operation will be described. When the user operates the remote commander 6, for example, the numeric keypad 8
When the user operates 1 to input an arbitrary channel number, an IR signal corresponding to the input channel number is output from the IR signal transmitting section 72. This IR signal is IRD
2 is received by the IR signal receiving section 39. The CPU 29
When a signal corresponding to the IR signal is supplied from the IR signal receiving unit 39, the tuner 21 is controlled so as to receive the channel corresponding to the input channel number.

The tuner 21 demodulates the signal of the channel corresponding to the channel number designated by the CPU 29 from the signal supplied from the LNB 1a, and outputs the signal to the QPSK demodulation circuit 22. The signal QPSK-demodulated by the QPSK demodulation circuit 22 is further input to an error correction circuit 23, and after error correction, is input to a demultiplexer 24. In the demultiplexer 24, the input signal is separated into video data and audio data, the video data is sent to an MPEG video decoder 25, the audio data is sent to an MPEG audio decoder 26,

Next, a description will be given of a case where a questionnaire survey, a viewer quiz with a prize, shopping, or the like is performed in a program such as PerfecTV (trademark) or the like that allows interactive access. When such a program involving voting is realized, a DM_voting_descriptor as shown in FIG. 5 is transmitted from the center to the IRD 2. On the IRD2 side, the CPU 29
Analyze the oting_descriptor and use the MPEG video decoder 2
5 to generate OSD data, and cause the television receiver 3 to display a voting screen (for example, a screen as shown in FIG. 9 described later).

The DM_voting_descriptor can be inserted up to 16 times in one program (event).

In FIG. 5, the descriptor_tag is
The type of scriptor (in this example, the voting desc
riptor). descriptor_length
Represents the length of the subsequent descriptor.

The voting_type indicates the type of voting, and there are four types as shown in FIG.

A vote whose voting_type is 1 is a non-information vote. In this case, as shown in FIG. 6, nothing is transmitted from IRD2 to the center. Such voting, for example, in questionnaire surveys,
Used to collect only the presence or absence of each answer.

A vote having a voting_type of 2 is a secret ballot. In this case, as shown in FIG. 6, the IRD 2 sends a service_id, event_id, voting_id,
And voting_code are sent.

Service_id represents the ID of the channel on which the program is being broadcast, and event_id represents the ID of the program. Further, voting_id indicates a voting ID, and voting_code indicates a number of an option (voting item) in the voting.

This secret ballot is also used for questionnaire surveys and the like.

The vote with the voting_type of 3 is a secret ballot. In this case, as shown in FIG. 6, in addition to the information transmitted in the case of secret ballot, CA_system_id and card_i
d is transmitted from IRD2 to the center. CA_system_id
Is the CA (Conditio
nal Access) ID of the system. card_id
Represents the ID of the IC card 33.

This signature voting is used, for example, in a quiz with a premium with a prize.

A vote whose voting_type is 4 is a registered name form with protection. In this case, the information transmitted from the IRD 2 to the center is the same as that in the case of the registered vote. In the case of registered voting, the length of the voting period (voting_duration) during which the user can vote is determined by the display period (d
isplay_duration). On the other hand, in the protected registered voting, the voting period and the display period have different lengths.

The protected voting is used, for example, for shopping.

Returning to FIG. 5, voting_id indicates a number when voting is performed a plurality of times in the program, and since up to 16 voting can be performed in one program, 0 to 15
Will correspond to either of the numbers.

The host_number indicates the number of the host to which the center providing this voting service is connected, among various hosts connected to TWIN'ET (trademark). When voting_type = 1, this host_number
Becomes invalid information.

Start_offset represents the time from the start time of the program to the start time of this voting. di
As described above, splay_duration and voting_duration represent the display period of the voting screen and the voting period, respectively. The voting screen is displayed during this display period, and voting is enabled during this voting period.

The voting_name_length represents the length of the voting name, and the voting name is described by a subsequent char.
"voting_code" represents a code of an option (voting item), and "tel_number" represents a telephone number to be transmitted when the option (voting item) is selected. co
de_name_length represents the length of the name of the option (voting item), and the name is described by a subsequent char.

Next, the voting process will be described with reference to the flowcharts of FIGS. The processing of this flowchart is started when the voting start time comes (when the time specified by start_offset has elapsed from the program start time). First, in step S1,
Processing for displaying a selection screen (voting screen) is executed. That is, the CPU 29 executes the DM as shown in FIG.
The _voting_descriptor is analyzed, and for example, OSD data of a boarding screen as shown in FIG.
To convert it to a composite video signal, output it to the television receiver 3 and display it. FIG. 9 shows a display example of a program in which the user selects a favorite movie and votes, and the program name is “special program ranking in 1995”. Please operate with "message is displayed. Furthermore, in this display example, the voting name (voting_name)
However, it is regarded as "the 10 best programs of the year you choose." This voting name is voting_nam in FIG.
It is represented by char immediately after e_length. Under the voting name, 10 of title 1 to title 10
The titles of the movies are displayed as voting items (options). The titles 1 to 10 are code names. In FIG. 5, code_name_le representing the length is shown.
It is represented by char immediately after ngth.

Further, as shown in FIG. 9, immediately before these ten titles 1 to 10, marks for selecting them are displayed as square buttons in FIG. The user selects one desired title from the ten movie titles thus displayed. The selection is made by operating the up key 88 or the down key 89 of the remote commander 6. That is, when the up key 88 or the down key 89 is operated, the cursor located on the mark is moved up and down (in FIG. 9, the cursor is displayed by making the located mark black). In the display example of FIG. 9, since the cursor is located on the mark corresponding to title 1, if the down key 89 is operated once, the cursor moves to the mark of title 2 and is operated once more. Moves to the title 3 mark.
After moving the cursor on the mark of the desired title, the user presses the enter key 92 of the remote commander 6.
By operating, the selection is confirmed.

The IR signal transmitting section 72 of the remote commander 6
When an up key 88, a down key 89, or an enter key 92 is operated, the I key corresponding to the operated key is
Outputs an R signal. This IR signal is received by the IR signal receiving unit 39 of the IRD 2, and the detection signal is supplied to the CPU 29. When the operation signal of the up key 88 or the down key 89 is input, the CPU 29 controls the MPEG video decoder 25 to change the OSD data of the cursor to
Generated in response to the operation.

In step S2, the CPU 29 waits until the operation signal of the enter key 92 is input. If the operation signal of the enter key 92 is input, the process proceeds to step S3, and the voting type shown in FIG. Vo shown in FIG.
Read from ting_type. As described above, there are four types of voting types. CPU2
No. 9 proceeds to step S4 when voting_type is 1 or 2, and proceeds to step S29 when voting_type is 3 or 4.

At step S 29, the CPU 29 sends the IC card 33 to the card reader interface 32.
It is determined whether or not is mounted. When the IC card 33 is mounted, the card reader interface 32
This is notified to the CPU 29. From this notification, the CPU 29 can determine whether or not the IC card 33 is mounted.

If it is determined that the IC card 33 is not mounted on the IRD 2 (card reader interface 32), the CPU 29 proceeds to step S30 and proceeds to step S30.
The message "Please insert a card" is displayed as shown in. Then, the process proceeds to step S31, where the CPU
In step S30, it is determined whether five seconds have elapsed after the message "Please insert a card" is displayed or whether the user has opened the lid 52 of the IRD2. If 5 seconds have elapsed without opening the lid 52, the process returns to step S1, and the subsequent processing is executed.

If it is determined that the lid 52 has been opened, the flow proceeds to step S32, and the CPU 29 displays a message "Please close the lid" as shown in FIG. That is, the user opens the lid 52 and attaches the IC card 33 to the IRD 2 in accordance with the message “Please insert a card” in step S10. Thereafter, the user closes the lid 52 according to the message of “Please close the lid” in step S32. CP
U29 waits until the lid 52 is closed in step S33, and returns to step S1 when the lid 52 is closed.

In step S29, the IC card 33
If it is determined that is mounted, the process proceeds to step S34, and the CPU 29 determines whether the IC card 33 is a correct IC card. The CPU 29 communicates with the IC card 33 via the card reader interface 32 when the IC card 33 is mounted on the IRD 2. If the IC card 33 is a correct card, the CP
U29 is connected to I via the card reader interface 32.
Communication with the C card 33 can be performed. If the IC card 33 is not a correct card, communication cannot be performed. In this case, the process proceeds to step S35, and the CPU 29 determines, for example, as shown in FIG. 12, that “access to a card is not established. Check whether a correct card is inserted.
The message "To V" is displayed for 10 seconds. The user
According to this message, the IC card 33 is
It will be replaced with the C card 33. When ten seconds have elapsed since the message was displayed, the process returns to step S1.

If it is determined in step S34 that the IC card 33 attached to the IRD 2 is a correct IC card, the process proceeds to step S36. Step S36
In, the CPU 29 determines whether the voting_type is 4. If voting_type is 4, the process proceeds to step S37, and the CPU 29 determines whether a password has been set. To perform voting of voting_type = 4, a password is required. If the password has not been set yet, the process proceeds to step S38, and the CPU 29 sets the password as shown in FIG. Please go. "Message is displayed. When this message is displayed, the user operates the enter key 92 after moving the cursor over a button on the screen on which the character “OK” is displayed. Then, the user operates the menu key 82 according to this message to display “menu”, and then selects an “initial setting” item from the “menu”,
Further, the user selects the item of "viewing age restriction setting" from the items displayed at that time, and performs an operation of setting a password. When the personal identification number is set, the personal identification number is stored in the IC card 33.

In step S38, when the "OK" button is selected or when the "OK" button is not selected and 30 seconds have elapsed, the process returns to step S1.

If it is determined in step S37 that the password has been set, that is, if the CPU 29
Proceeds to step S39 when the notification that the personal identification number is already registered is received from the IC card 33 through the card reader interface 32, and for example, as shown in FIG. And enter your PIN with the number buttons. " At this time, the CPU 29 simultaneously displays the input field for the personal identification number and the button on which the word “cancel” is displayed. In accordance with this message, the user operates the numeric keypad 81 of the remote commander 6 to enter a personal identification number, or selects a “cancel” button with a cursor.

The CPU 29 determines in step S40
If it is determined that the "cancel" button has been selected, the process returns to step S1, and the subsequent processing is executed. On the other hand, if it is determined in step S40 that the personal identification number has been input, the process proceeds to step S41 and the CPU 29
Determines whether the personal identification number is a correct personal identification number. That is, the CPU 29 transmits the input personal identification number to the IC card 33 via the card reader interface 32.
To supply. The IC card 33 determines whether or not the input personal identification number is equal to the already stored personal identification number, and notifies the CPU 29 via the card reader interface 32 of the determination result. From this notification, the CPU 29 determines whether the password is a correct number. If the password is not correct, the CPU 29 proceeds to step S4
Proceed to step 2 to display a message "The password is incorrect, please re-enter the password" as shown in FIG. Thereafter, the process returns to step S40, and it is determined whether the "cancel" button has been selected or the password has been entered, as in the case described above.

If it is determined in step S41 that the input password is correct, the flow advances to step S4.
If it is determined in step S36 that voting_type is not 4, the process proceeds to step S4.

In step S4, the CPU 29
It is determined whether or not the previous re-access remains. That is, although the details will be described later, the user performed a voting operation in the previous voting, but the other party's telephone line was busy or the user's own telephone line was busy. In some cases, the voting may not be completed yet. In this case, that voting_type
Is one of 1, 2, and 3, the user is required to start voting again from the beginning (steps S15 and S19 described later). Voting_type is 4
In the case of, the voting content is held in the EEPROM 38 because it is an important voting (steps S10, S16, S18 to be described later). In this case, it is necessary to make another access to the previous voting, so it is necessary to distinguish whether the access to be made is the access for the previous voting or the access for the current voting. is there. Therefore, in step S4, it is determined whether or not type 4 voting remains.

If it is determined in step S4 that voting of type 4 remains, the process proceeds to step S7, where the CPU 29 causes the television receiver 3 to display an image as shown in FIG.

That is, the CPU 29 displays the voting items selected by the user in the current voting and the voting items selected by the user in the previous voting. In the display example of FIG. 16, the title of the movie "Title 5" is displayed as the vote item selected this time, and "Title 4" is displayed as the vote item of the previous voting.

At this time, as shown in FIG. 16, the CPU 29 displays the message "Waiting for access. Do you want to cancel the previously selected one and execute access?" Is displayed, and a button is displayed that displays a message "execute this time". The user operates the left key 90 or right key 91 of the remote commander 6.
To move the cursor right or left, and select one of the buttons. Then, when the selection is confirmed, the user operates the enter key 92.

Next, in step S8, the CPU 29
Determines whether the button of "leave the previous one" or the button of "execute this one" has been selected. If it is determined that the button of "leave the previous one" has been selected, the process proceeds to step S1. Return and repeat the subsequent processing. That is, in this case, the previous voting screen is displayed again, and the user performs access processing again from the voting screen.

On the other hand, if it is determined in step S4 that there is no previous type 4 voting, the process proceeds to step S5, and the CPU 29 displays an image as shown in FIG. In this display example, a button displaying the word "Cancel" and a button displaying the word "Execute" are displayed on the current voting screen together with the message "Perform access?" Is displayed. The user presses one of the two buttons with the left key 9
Select by operating 0 or the right key 91. And
When the selection is confirmed, the user operates the enter key 92.

In step S6, the CPU 29
It is determined whether the "cancel" button or the "execute" button has been selected. If it is determined that the "cancel" button has been selected, the process returns to step S1, and the subsequent processing is executed.

On the other hand, in step S6,
If it is determined that the “execute” button has been operated, the CP
U29 proceeds to step S9. If it is determined in step S8 that the user has selected the "execute this time" button, the process also proceeds to step S9.

In step S9, the CPU 29
For example, as shown in FIG. 18, the message “Accessing, please wait as is” is displayed on the television receiver 3.

Then, the process proceeds to a step S10, wherein the CPU 29
Executes a process of storing the success data in the EEPROM 38. The success data includes the service_id (channel number) of this voting program,
start_offset (the time from the start time of the program to the start time of this voting) and the voting_code (voting item number) of the selected voting item are included.

Next, at step S11, the CPU 29
Clears (resets) the success flag. This is to prepare for a case in which, when the access is executed in the next step S12, the telephone line of the other party is busy or the telephone line at home is in use, so that a vote cannot be established. If a vote is established, a success flag is set in step S20 as described later.

Then, the process proceeds to a step S12, wherein the CPU 29
Performs an access process. That is, the CPU 29
Controls the modem 34 and selects the voting_cod selected by the user.
The access operation is started for the telephone number (tel_number) specified corresponding to e. The modem 34 has a CP
In response to the control from U29, the calling operation for the instructed telephone number is started. Then, when the telephone line is closed with the other party (center), the CPU 29 causes the center to transmit transmission information as shown in FIG. 6 corresponding to the voting_type.

That is, the voting is voting_t
If ype = 1 voting, no information is transmitted, and if voting_type = 2 voting, ser
vice_id, event_id, voting_id, and voting_code are transmitted to the center. The voting is voting_type = 3
Or, if voting_type = 4, voting
In addition to the transmission information in ing_type = 2, CA_system_id, ca
rd_id is further transmitted to the center.

Therefore, on the center side, voting_typ
If e = 1, the presence or absence of voting can be counted and voted
In the case of g_type = 2, it is possible to total up which voting was performed for which channel, which program, which voting, and which voting item. voting_type = 3 or v
When oting_type = 4, it is possible to further know the user who has voted and the contract conditions.

Then, the process proceeds to a step S13, wherein the CPU 29
Determines whether a vote has been approved. If the vote is not successful, the cause may be that the other party's phone line is busy, that the user's home phone line is busy, or that the phone line is connected. It is determined whether there was a problem.

If voting cannot be performed because the telephone line of the other party (center side) is busy, the process proceeds to step S14, and the CPU 29 further determines that the current voting is of type 4 voting. It is determined whether or not there is. If the current voting is not the type 4 voting but the type 1 to type 3 voting, the process proceeds to step S15, and the CPU 29
As shown in FIG. 19, a message “access failed, please try again” is displayed for 5 seconds. If the current voting is type 4 voting, the process proceeds to step S16, and the CPU 29, for example, as shown in FIG.
The message "This access can be re-accessed with the program-related center access on the menu"
Display for 0 seconds.

The user selects "menu" according to this message, and selects "program related" from the menu.
Is selected, and then the item of “center access” is sequentially selected from the items of “program related”.
29 reads out the success data stored in the EEPROM 38 in step S10 and executes an access process corresponding to the success data. Therefore, the user can re-access with the contents of the selection that has already been made without performing the selection processing again.

That is, as described above, in the case of voting of type 4, voting_duration is equal to display_durat
does not match the ion, in other words, the user
Voting can be performed even after _duration expires. This voting can be performed by selecting an item of “program related” in “menu” and further selecting an item of “center access” from “program related”.

In step S13, when it is determined that the voting is unsuccessful because the home telephone line is in use, or when the voting is unsuccessful due to some problem in connection of the telephone line. If determined,
Proceeding to step S17, the CPU 29 determines whether or not the current voting is type 4 voting. If the current voting is a type 4 voting, the process proceeds to step S18, where the CPU 29
As shown in Fig. 21, the message "Access failed, telephone line is in use or not connected properly" and the message "This access can be re-accessed by program-related center access in the menu" are displayed. , 30
Display for seconds. If the current voting is not the type 4 voting but the type 1 to type 3 voting, the process proceeds to step S19 and the CPU 2
No. 9, as shown in FIG. 22, displays a message "Access failed, telephone line is in use or not properly connected" for 5 seconds.

On the other hand, if it is determined in step S13 that the vote has been established (the information has been successfully transmitted to the other party), the process proceeds to step S20, and the CPU 29 sets the success flag cleared in step S11. . Then, in step S21, it is determined whether a response message has been transmitted from the center. When the response message has been transmitted, the process proceeds to step S22,
The CPU 29 displays the received response message for 10 seconds, for example, as shown in FIG. In the display example of FIG. 23, a message “Thank you for participating” is displayed.

If a response message has not been transmitted from the center, the process proceeds to step S23, and the CPU 29
For example, as shown in FIG. 24, a message “access completed” is displayed for 5 seconds.

In step S22 or S23, a state in which a response message or a message of "access completed" is displayed, or in steps S15 and S1
In step S18 or S19, the display_du is displayed while the message “access failed” is displayed.
When the ration has expired, if 5 seconds have already elapsed since the display of the message was started, the CPU 29
The display screen is deleted. If five seconds have not yet elapsed, the display screen is deleted after the lapse of five seconds. Thus, the display screen is displayed for at least 5 seconds.

After the response message is displayed for 10 seconds,
Alternatively, after a message of “access completed” is displayed for 5 seconds, the process proceeds to step S24. When 5 seconds have elapsed since the message "Access failed" is displayed in step S15 or S19, or 30 seconds have elapsed since the message "Access failed" is displayed in step S16 or S18. Also proceeds to step S24.

In step S24, the CPU 29
Determines whether the success flag is set.
If the success flag is not set, the access has failed, and it is necessary to execute the access again. Therefore, the process returns to step S1, and the subsequent processing is executed.

On the other hand, in step S24,
If it is determined that the success flag is set,
The CPU 29 proceeds to step S25 and proceeds to step S10
And is included in the success data stored in the EEPROM 38.
It is determined whether or not the service_id and start_offset match the voting service_id and start_offset at the present time. If the service_id of the success data does not match the service_id of the current voting, the data stored in the success data is data of a different program (channel). Also, even if the service_ids match, if the start_offsets do not match, the data stored as the success data will be the data in the voting prior to this time. Therefore, in these cases, the process returns to step S1, and the subsequent processes are executed again.

The determination in step S25 is for determining whether or not the user has performed voting, the success flag has been set, and the voting is still continuing. The user's voting operation is voting_duratio
If performed within the time n, the service_id and start_offset stored in the success data match the service_id and start_offset of the current voting. Therefore, in this case, the process proceeds to step S26 and the CPU 29
Displays only voting items (options) registered in the success data with a mark as shown in FIG. 25, and displays other voting items without a mark.
In the display example of FIG. 25, only “Title 5” is displayed with a mark, and the other “Title 1” to “Title 4” and “Title 6” to “Title 10” are marked. It is displayed without being attached. As is apparent from a comparison of FIG. 25 with FIG. 9, since the titles other than “Title 5” are not marked, the user can no longer select a voting item (voting has been completed. Can be intuitively recognized.

Next, the process proceeds to a step S27, where the CPU 29
Waits until the display_duration expires, and when it expires, the process proceeds to step S28, where the display of the voting screen is deleted, and the process ends.

On the other hand, after the user has effectively voted,
Voting_duration expires before the screen shown in FIG. 25 is displayed, and the next voting (different voting_id
If the voting has been started, the success data and the current voting will be
And start_offset will not match. In such a case, displaying the previous voting screen as shown in FIG. 25 will give a misunderstanding to the user.
Therefore, in this case, the process returns to step S1, and a voting screen of a new (next) voting is displayed.

In step S25, it can be determined whether or not new voting has started using the success data and the current voting service_id and voting_id. However, voting
When _id is used, there is a possibility that the same voting_id is used in different programs of the same service_id (channel), so that it is necessary to use event_id (program ID) for determination. As a result, not only the data that needs to be determined increases, but also the event_id may be repeatedly used a plurality of times when the number of programs on the channel is large. In this case, the same voting_id and event_id may be assigned to different voting. On the other hand, start_offset has a high probability of being different for each program, so service_id and start_offset
Is used, each voting can be uniquely specified.

FIG. 13 (step S38), FIG.
When the display_duration has elapsed while the display of FIG. 17 (step S5) or FIG. 16 (step S7) is being performed, the CP
The U29, for example, displays a status display message of "cannot be executed because the expiration date has expired", and then waits for the elapse of 5 seconds to erase the display of the voting screen.

Among the processes shown in the flowcharts of FIGS. 7 and 8, the message display process and the mark display process after the user has voted are extracted and shown in the flowcharts of FIGS. 26 and 27. As shown.

In FIG. 26, the CPU 29 executes processing for storing success data in step S51.
This process corresponds to the process of step S10 in FIG. As described above, this success data includes the service_id and start_offset of the voting to be accessed, and the voting_cod of the selected voting item.
e is included.

Next, in step S52, the CPU 2
9 resets the success flag. This processing corresponds to step S11 in FIG. Next, step S53
The CPU 29 executes an access process corresponding to the success data stored in step S51. This access execution process corresponds to the process of step S12 in FIG.

Next, in step S54, the CPU 29 waits until the access is completed. When the access is completed, the CPU 29 proceeds to step S55 to determine whether the access is successful. Steps S54 and S55 correspond to step S13 in FIG.

If it is determined in step S55 that the access has been successful, the CPU 29 proceeds to step S56,
Set success flag. The process in step S56 corresponds to the process in step S20 in FIG. Next, proceeding to step S57, the CPU 29 executes a success message display process. The processing in step S57 corresponds to the processing in steps S22 and S23 in FIG.

On the other hand, if it is determined in step S55 that the access has not been successful, the CPU 29 proceeds to step S58 and executes a failure message display process. The processing in step S58 corresponds to step S1 in FIG.
5, S16, S18, and S19.

On the other hand, in the mark display processing of FIG. 27, the CPU 29 determines whether or not the success flag is set in a step S61. This step S61
Corresponds to the processing in step S24 in FIG. If the success flag is set, step S6
Proceeding to 2, the CPU 29 determines whether or not the success data and the current voting match with respect to service_id and start_offset. The processing in step S62 corresponds to the processing in step S25 in FIG. Step S
At 62, when it is determined that the voting after the voting at the time when the success data is stored has not been started (the success data and the current
When it is determined that they match with respect to id and start_offset), the CPU 29 proceeds to step S63, displays only the voting items registered in the success data with a mark, and does not mark other voting items. Execute the process to display. That is, an image as shown in FIG. 25 is displayed. The process in step S63 corresponds to the process in step S26 in FIG.

On the other hand, if it is determined in step S61 that the success flag has not been set, or if it is determined in step S62 that the next voting has started, the CPU 29 proceeds to step S64. The process proceeds to execute a process of marking and displaying all voting items. That is, an image as shown in FIG. 9 is displayed. The process in step S64 corresponds to the process in step S1 in FIG.

As described above, by controlling whether or not to display a mark at the head of a voting item (option), it is possible to clarify the difference between a voting screen and a non-voting screen. Accordingly, the user can easily recognize whether or not the voting has already been completed, and can suppress an erroneous operation such as performing re-access even though the voting has already been completed.

In the above embodiment, a predetermined mark is displayed at the head of the option, and when the access is successful, only the mark corresponding to the selected option is displayed, and the other marks are erased. However, the end of voting can be recognized by changing the color or shape of the mark. In short, the state after voting may be different from the state before voting. In addition, the mark is
Shapes other than buttons are also possible.

Further, in the above embodiment, the case of perfect TV has been described, but the present invention is not limited to this, and other digital satellite broadcasting, CAT
The present invention can be applied to V and the like.

[0117]

According to the receiving apparatus of the first aspect and the display control method of the ninth aspect, when any one of the voting items is selected, the display state of the mark is changed to the voting item. Since the state is different from the state before the selection, the screen that can be selected and the screen that cannot be selected can be easily recognized. Thereby, erroneous operation by the user can be suppressed.
