FIG. 4 shows a configuration diagram of the program management system. The main role of the program management system 24 is to manage the schedule of the program, and send a transmission instruction to the program editing system 22 based on the schedule. In addition, program arrangement information is generated from a schedule. The program schedule 240 is stored in the schedule management server 249 by the schedule input terminal 241. The program schedule 240 describes information necessary for generating program arrangement information such as broadcast date and time and identification of free broadcast / paid broadcast. The schedule management server 249 stores a program schedule 243 for several days. The number of days to be saved, the number of saved program schedules, and the like are determined by operating conditions. The transmission operation terminal 242 sends the schedule management server 2
49 shows information on programs to be broadcast (storage location, file name, etc.)
, And instructs the program editing system 22 to transmit the file.

PSI / SI generation device (program arrangement information generation device)
The H.245 generates program arrangement information from the data transmitted from the schedule management server 249 at a timing before the start of the program, and sends it out to the multiplexer (MUX) / scrambler 28 (note that PSI (Program Specific Informatio)
n, program identification information) is information necessary to obtain data constituting the selected program when the user selects a channel, such as a TS number, an ES number, and the presence or absence of conditional access. Is described. In addition, SI (Service
information, program arrangement information) are various types of information defined for the convenience of program selection. For example, EPG (Elect
ronic Program Guide), drama outline, performers, program genre, etc. ). For example, in the case of BS digital broadcasting, it is conceivable to transmit not only the program arrangement information of the own station but also the program arrangement information of the entire network (referred to as all-station SI). The exchange of data with the compilation of the program arrangement information is also performed. When the broadcast program to be started performs limited reception such as pay broadcasting, the schedule management server 249 and the customer management system 25
An EC, which is one of program arrangement information having information such as a key for descrambling, is stored in an M generation device (key information generation device) 246.
Information required to generate M is sent (note that ECM (En
“Titlement Control Message, program information” is common information, in which information about a program and key information for descrambling (decryption) are described. ). The ECM generation device 246 converts the actually generated ECM into a multiplexing device (MUX) / scrambler device 28 according to the program schedule.
And gives an instruction to start scrambling.

Next, FIG. 5 shows a configuration diagram in the customer management system. In the customer management system 25, a call center 251 is set up as an interface with the outside, where a viewer applies for a subscription. The registration terminal 252 has a role of storing the subscription application information received by the call center 251 in the customer / billing management server 253. client/
The accounting management server 253 transfers accounting information such as a customer list, a subscription fee, and a monthly viewing fee to the credit company 29. In order to generate contract information for each subscriber and individual information which is one of program arrangement information called EMM (Entitlement Management Message) for decrypting,
The customer / billing management server 253 transfers the required data to the EMM generation device 254 (EMM is individual information including a key for decrypting contract information for each subscriber and common information. Double encryption is common.). BS
In the case of digital broadcasting, delivery of key information and the like managed by an external organization called a CAS management center 26 is performed by the EMM generation device 254. The EMM generation device 254 further includes:
It also exchanges information such as key information with the program management system 24. The EMM generated by the EMM generation device is passed to a multiplexer (MUX) / scrambler device 28.

Next, a receiver for receiving a broadcast service will be described. FIG. 6 shows a simple configuration in the receiver and an operation explanatory diagram on a screen image by a remote control operation. The receiver 7 acquires information from a satellite via the antenna 6. In the receiver 7, necessary information is extracted from the acquired information by the tuner 71, and the carousel is stored in the memory (1).
(RAM) 72. At this time, the data format to be stored is DII (Download Info Indicat
ion) and DDB (Download Date Block) are analyzed and stored in module form. The receiver 7 transfers the module to be presented on the screen from the stored modules to the browser 73. Browser 73 uses the BM in the module

(Nonvolatile Random Access Memory) The data of 74 is read or written and analyzed.
The memory (2) (NVRAM) 74 can store information such as individual registration. The browser 73 further constructs screen data based on the information, and writes the screen data to be displayed on the TV 8 into the graphic memory 77.
The receiver 7 displays the screen data written in the graphic memory 77 on the TV 8.

Next, the operation of the remote controller will be described. When the user moves the displayed screen such as selecting another screen from the displayed screen 80, the user selects the screen by operating the remote controller 76. In the case of the illustrated example, the cursor of the remote controller is located at the position of the box 81 in the initial state. Here, if the user wants to see “4 pages”, for example, the remote control operation (cross key)
By operating in the order of “right, down, set”, the remote control I / F 75 in the receiver 7 receives the operation information of the remote control 76 and gives the browser 73 support for cursor movement. When the browser 73 analyzes the operation information of the remote controller 76, the receiver 7 recognizes the movement of the cursor and can present the next screen “4 pages”. In addition, the browser 73 displays the movement of the cursor on the screen, so that the user can visually confirm the operation of the remote controller (the instruction on the screen moves from the box 81 to the box 82 and from the box 82 to the box 83).

Next, an example of desirable receiver specifications will be described. The memory capacity of the BS receiver required when performing this service by BS digital broadcasting is, for example, as follows. Since this memory capacity is the minimum required memory in the BS receiver standard, this service can be received by all BS receivers.

This figure is an example of a “main menu screen” in which a service provided in the present service first presented by selecting a channel is specified. The “Main Menu Screen” includes the basic services “weather forecast”, “program guide & memo pad button”, “bulletin board”, “flash report”, “banner / telop advertisement”, and “variable service menu” "including. Then, the screen 1001 displays an image 1 “data channel”, an image 2 “logo”, and an image 3 “advertisement image”.
, And each text resource of texts 1-6. Here, the carousel transmission method will be described using this screen as an example. The carousel transmission method is a method in which data required for a program is not read all at once on the receiver side, but the data is divided for each screen and a plurality of divided data are repeatedly transmitted in a constant cycle. is there.

FIGS. 8 and 9 are explanatory diagrams (1) and (2) of the carousel transmission system, respectively. In this broadcasting service, a carousel transmission method is used as a transmission method of channel data, and a multi-part format is used as a resource storage method. A case where resources for one screen are stored in one module will be described below. The resources for one screen may be stored in a plurality of modules, or the resources for a plurality of screens may be stored in one module.

In the carousel transmission system, this screen 100
1 is transmitted, the information on the screen 1001 is converted into an image, a figure,
Database information, BML (Broadcast Markup Language)
Divided into resources such as documents (BML is a description language for broadcasting, and HTML (Hyper Text Mar
kup Language). ). When transmitted as module 0, the BML document 1002 contains text information, ECMA (European Computer Manufactures A).

The ECMA script is a type of programming language that can execute processing by describing simple logic to complement the functions of the application. The ECMA script is used in this service to extend the functions of the browser, and dynamically changes the display screen and stores data in memory (2).
(NVRAM) 74 is used when storing. image,
The figure file designation information describes the figure and the file names of the images 1 to 3, and the file is displayed at a designated place on the screen. The style information describes screen layout information such as text sentences, graphic files, and image files. Information of the image 1 is described in the image file 1003. Similarly, the image files 1004 and 1004
Reference numeral 5 describes information of the images 2 and 3. Database information is described in the database file 1006. In this example, data such as a weather forecast is described in a table format in the database information. This database file 1006 is operated as needed.

Next, a resource list 1007 including information on each resource is created. One screen resource 1008 (BML document 1002, image files 1003 to 1005, database file 1006
) And a resource list 1007 to form one module. Next, the module is divided into block data 1009 of unit size, and header information 1010 is attached to each block data to create a DDB 1011. DDB0 to m form data for one screen (module 0).

This operation is performed for all screens (modules 0, 1,...) Stored in one carousel. After creating DDBs for all screen information,
DII (Downloa) is a section with module mapping information that indicates which module
d Info Indication) 1012 is created. With all DDBs
DII is combined to form one carousel 1013.

Next, a service outline of the data file will be described. This service is a service provided to all types of viewers. In addition, the audience may be appropriately narrowed down, such as young people, middle-aged people, housewives, OLs, and businessmen. Here, as an example, a basic service that can be watched at any time and a variable service in which the audience is changed for each time frame obtained by dividing the day into minute times are configured. For example, the basic services that can be viewed at any time provide free content such as weather forecasts, news, and advertisements, and the near-on-demand variable service that takes into account the viewer's life time includes hobbies and entertainment, Content such as life information, coupon information, and advertisements can be provided free of charge, or depending on the information content, for a fee.
The type of content mainly deals with still images (image data and the like), character data, and audio, but may be moving images. This service can have a multi-service configuration in which basic services, variable services, free / paid services, and the like are mixed in one channel. This service is a service that has a new aspect of simply customizing the broadcast data, in contrast to a service that is passive for users called broadcasting. Note that the channel contents of this service such as basic / variable service, paid / free service, member / non-member service, etc. can be appropriately configured.

FIGS. 10 and 11 are explanatory diagrams of a program table (1).
And (2) are shown as an example. FIG. 10 shows this service.
For example, it is an image of a program guide in a certain time zone when transmitted in a transmission area of about 1 Mbps. This data channel includes a basic service 1101 and a variable service 1102. Basic services include "Weather Forecast", "Breaking News",
Services such as "program guide &notepad" and "bulletin board"
The service can be received at any time by selecting the channel for this service. Variable service 110
In 2, the available services change depending on the time. For example, the newspaper is between 6:00 and 8:00, but it is from 8:00 to 12: 0
At 0, it becomes "cooking", and at 12: 00-15: 00, it becomes "game", and the service received up to that point changes. Regarding the program contents, a service organization that responds to user needs is considered in consideration of the target audience according to time.

FIG. 11 shows this service, for example, 3M
5 shows an image of a program guide when transmitted in a transmission area of about bps. Here, in a certain time zone, the number of variable services that can be broadcast in one time frame can be increased by the increase in the transmission area. In addition, the number of variable services for each time frame can be fluidly organized. For example, in a certain time frame, four variable services (“newspaper”, “cooking”, “game”)
"Qualification") 1103 is broadcast, but in other timeframes 3
The variable service (“music”, “mail order”, “picture book”) 1104 is provided, and the transmission area per service may be increased like “music” here. In both cases,
As an example, the basic service 1101 can be transmitted on the carousel 1 and the variable service 1102 can be transmitted on the carousel 2.

FIG. 12 is an explanatory diagram of the service configuration. In this service, a “main menu screen” 1201 composed of a “basic service” and a “variable service menu” that can be viewed only by selecting a channel, and “viewing is possible by selecting with a remote control” Basic service "detail screen" Program guide & memo pad detail screen "
1202, a “detailed advertisement” 1203, and a “variable service detail screen” 1204, which is a variable service.

FIG. 13 is an explanatory diagram of the service hierarchy.
In this service, each service (service screen) is hierarchized in order to improve the user's selectivity of information using the remote controller. The “main menu screen” 1301 is a screen of the highest hierarchy first presented by selecting a channel performing this service. In this example, as the services that can be received on the “main menu screen” 1301, the weather forecast, bulletin board, bulletin, banner advertisement, and variable service “menu” 1304 of the basic service are exemplified. "Program Guide & Notepad Detail Screen" 1302
This is a screen that is presented by selecting the “program guide & memo pad button” on the “main menu screen” 1301, and has a hierarchy following the “main menu screen” 1301. “Detailed advertisement screens 1 and 2” 1303 are screens that are presented by selecting a viewable banner / telop advertisement on the “main menu screen” 1301 and the “program guide & memo pad detail screen” 1302. Program guide & memo pad detail screen "1302. The “menu” 1304 of the variable service is a “detail screen” 13 of the next layer.
The main menu screen 1301 is composed of buttons and the like for presenting the user 05. “Detailed advertisement screen 3” 1306 is a screen of the lowest hierarchy. This is presented by selecting a banner / telop advertisement on the “detail screen” 1305 of the variable service.

4. Operation and function of service 4-1. Menu Display Operation FIG. 14 shows a service viewing sequence diagram. This figure 1
4 is a viewing sequence between the user and the receiver when actually receiving the service. The sequence of the basic service viewing sequence between the user and the receiver is shown in step 101.
It becomes like the flow of ~ 111. The viewing sequence starts when the user selects a channel on which the service is performed by the remote controller 76 (101). When the user selects a channel, PSI / SI
Is acquired (102). The program arrangement information is a collection of sequence information which is a target for selecting program data of a desired channel from a network composed of multiple channels multiplexed in digital broadcasting, and program information such as conditional access. . Further, the content of the acquired program arrangement information is analyzed, and the next operation of the receiver is performed.

By analyzing the acquired program arrangement information, data called a module of the entry carousel (carousel 1) to which the “main menu screen” presented first in the service is transmitted is stored in the memory (1) in the receiver.
It is stored on the (RAM) 72 (103). Acquiring the carousel means writing data of each module constituting the carousel to the memory (1) (RAM) 72 in the receiver. Since the memory (1) (RAM) 72 basically uses a RAM which is a volatile memory, if power is cut off during writing or a channel is moved, data written up to that point has been lost. In this case, the operation may be restarted from the beginning. The receiver 7 has a memory (1) (RAM) 72
Among the modules stored above, a file group constituting an entry module (including a file constituting the “main menu screen”) is transferred to the browser 73 and is operated to be presented on the TV screen (104). . By the steps 102 to 104 in the receiver 7, the user can view the "main menu screen" displayed on the television 8 (105). The actual screen image is a screen as shown in FIG.

FIG. 15 is an explanatory diagram of a main menu screen for selecting a basic service. When the user wants to view the detail screen of the basic service, such as the “program guide & memo pad detail screen”, the user selects the item of the basic service to be viewed on the “main menu screen” with the remote controller 76 (106). The image is such that the “program guide & memo pad button” 151 in FIG. 15 is selected by moving the cursor by remote control operation.

A module including files constituting the “program guide & memo pad detail screen” is called a “main menu screen”.
If it exists in the same entry carousel (carousel 1) (it basically exists in the same carousel for free broadcasting), the "Program guide & notepad detail screen" is already stored in the memory (1) (RAM) 72 of the receiver. Since the module is stored, a group of files constituting the screen is immediately transferred to the browser to present the screen (107). The user can view the "program guide & memo pad detail screen" which is the basic service screen by step 107 of the receiver 7 (108).

FIG. 16 is an explanatory diagram of a program guide & memo pad detail screen of the basic service. When returning to the “main menu screen” from the basic service screen, the user needs to use the “return button” prepared on the screen as shown at 152 in FIG.
(Has a function to return to the main menu screen) is selected (109). On the receiver 7 side, memory (1) (RAM) 72
The file group of the entry module stored above is re-presented (110). Step 11 on the receiver 7 side
0 allows the user to view the "main menu screen" again (111).

Next, a series of flow of the variable service viewing sequence between the user and the receiver is described in steps 112 to 11.
It looks like the flow of 4. When the user views the variable service, the user selects a desired item in the variable service menu on the "main menu screen" by using the remote control (112). The image is as shown in FIG. When viewing the variable service, if the variable service is a free broadcast and a module including a group of files constituting each screen exists in the entry carousel, the receiver side step 1
Operations similar to steps 07 and 110 are performed. However, if the variable service is charged (or free but the carousel is different from the entry carousel), a new carousel (carousel 2) is acquired as in step 113 of the receiver 7, and the module is stored in the memory (1) (RAM). ) 72. At this time, the module of the entry carousel taken in before the carousel 2 may be overwritten and erased by the receiver 7. Here, it is assumed that “recommended tonight” 153 is selected as an example (see FIG. 15).
On the receiver 7 side, when a module including a group of files constituting the selected “detail screen” among the modules of the carousel 2 is stored in the memory (1) (RAM) 72, the corresponding group of files is deleted. The data is transferred to the browser and presented to the television (display medium) (114). The user can view the selected “detail screen” of the variable service displayed on the television by steps 113 and 114 of the receiver 7. FIG. 17 shows an explanatory diagram of the detail screen. The above is the viewing sequence of the basic service and the variable service between the user and the receiver.

FIG. 18 is a flowchart showing the service selection in the receiver. FIG. 18 is a flowchart in the receiver 7 based on the service selection after the “main menu screen” is presented. The flow in the receiver when viewing each service screen in the present service is started from the time when the user receives an event that occurs when the user selects a service item (button) by operating the remote controller, similarly to the channel selection flow (201). . Upon receiving the user's remote control operation, the receiver 7 determines whether a module including a file group constituting the screen of the service selected first is currently present in the memory (1) (RAM) 72 (20).
2). If the module exists in the memory (1) (RAM) 72, the file group in the module is transferred to the browser, and instructed to be presented on the television (display medium) (203).

If the corresponding module is a memory (1) (RA
M) If it does not exist on 72, the program arrangement information is acquired / analyzed by the link information acquired when the button was selected (information indicating where the necessary information is located, road target information) and scrambled. (When encryption is performed on paid broadcasts, etc.)
Releases the scramble (205). The module in the corresponding carousel selected in step 205 is stored in the memory (1) (RAM) 72. When the module including the file group constituting the screen of the selected service is stored in the memory (1) (RAM) 72, an instruction to present the module to the television (display medium) is issued as in step 203. These operations allow the user to view the screen of the selected service on the television (204).

4-2. Registration Display Operation (Weather Forecasting Service) Here, an operation will be described in which a program, item, screen, or the like desired by a user is stored as registration information, and a screen is displayed based on the registration information. Here, a weather forecast service will be described as an example, but the present invention is not limited to this, and the present invention can be applied to an appropriate service.

The weather forecast service in the present service is a service that allows a user to view whenever he wants to see it. In order to present the weather forecast of the area (region) that the user wants to know immediately, the service registers the area. The registration of the area means that the user selects the area you want to see first from 47 prefectures in advance, and lets the receiver remember that area, so that the area selected the next time you receive the weather forecast service will be the default Is to be displayed. In this example, the number of areas to be registered is 2 and the selectable area items are 47 prefectures. If you want to change the registered area (even if you want to know the weather forecast other than the displayed area), you can reselect / re-register the area as many times as you want. If the area has not been registered, the area is set as a default area, and the weather forecast for Tokyo and information indicating that the area can be registered are displayed.

FIG. 19 is an explanatory diagram of a data image when the present weather forecast service is performed. The data (351) actually transmitted as a broadcast on the transmission side in the weather forecast service includes a weather forecast frame (352) and weather data (353). The weather forecast frame (352) is an image such as a layout frame when displayed on the screen. In the case of embedding the “Tokyo weather forecast” and “registered message” as initial values in advance as in this example, is there. The weather data (353) is data in which data to be embedded in the weather forecast frame (352) is summarized in a table format. The data held in the receiver 7 includes the registration data (35
6) is provided in the nonvolatile memory (2) (NVRAM) 74. The weather forecast display (357) displayed on the TV screen is
Weather forecast frame (352), weather data (353) and memory (2) (NVRAM) 7 in the receiver sent as broadcast
4 data (356). Next, an actual screen image and a viewing sequence will be described with reference to the drawings.

FIG. 20 is a sequence diagram between the user and the receiver when viewing the weather forecast service. FIG. 21 is an explanatory diagram of a screen for the weather forecast service. The weather forecast service has items to be registered, and a sequence before registration and a sequence after registration will be described separately. First, an initial state in which an area is not registered will be described.
Since the weather forecast service is a service received on the “main menu screen”, the user displays a “main menu screen” by operating a remote controller by selecting a channel or a service (301).

The user can view the initial state of the weather forecast service by displaying the "main menu screen" (302). In the initial state image of the weather forecast, as shown in a box 261 in FIG. 21, a message prompting registration of the area is displayed together with the weather forecast of the area where the data is already embedded at the time of transmission in the initial state (Tokyo is in this service). Is done.

When the user registers an area, the user moves the cursor to the registration message by operating the remote control, and selects a box 262 in FIG. 21 to display a registration area candidate such as a box 263 in FIG. 21 ( In the case of this service, a display area of 47 prefectures is secured by pull-down display.) Further, the user selects a registration area from the registration area candidates using the remote controller.
In the case of the box 263 in FIG. 21, as an example, “Osaka”
Is selected as a registration area (303). The receiver registers and saves the area selected by the area selection in the nonvolatile memory (2) (NVRAM) 74 of the receiver (304). The receiver stores the weather forecast data corresponding to the selected area "Osaka" in the memory (1).
(RAM) 72 is pulled and embedded in each of the weather forecast frames on the "main menu screen" (305). The receiver side operation, steps 304 and 305 in FIG. 20, allow the user to view the weather forecast in the registered area (306). A screen image of the weather forecast display of the registration area is as shown in a box 264 in FIG.

Next, the user /
The viewing sequence between the receivers will be described. When the user displays the “main menu screen” by selecting a channel and selecting a service (307), the receiver side:
Memory (2) (NVRAM) where the registration area is stored 7
4 is read, and the weather forecast information corresponding to the area is embedded in the weather forecast frame (309). This allows the user to view the weather forecast of the area registered in advance while displaying the “main menu screen” (308). Imagewise, box 264 in FIG.
Is a display embedded when the "main menu screen" is displayed.

FIG. 22 shows a flowchart of the weather forecast service in the receiver. The flow in the receiver is started by channel selection or service selection to display the “main menu screen”. Here, the case of channel selection will be described. In the case of service selection, the flow is almost the same (401). First, in order to store a module including the “main menu screen” in the memory (1) (RAM) 72, the carousel 1 which is an entry carousel is selected and acquired based on the program arrangement information (402). When the files that make up the “Main Menu screen” are passed to the browser, memory (2) (NV
It is determined whether an area is registered on the (RAM) 74 (403). If the area is memory (2) (NVRAM)
If it is registered on the memory 74, the browser acquires the registration information such as the registration area from the memory (2) (NVRAM) 74 (404). Such registration information can be stored in advance by the user using the remote controller 76 or the like as described below. The browser that has acquired the registered area information,
The weather forecast data corresponding to the registered area is selectively obtained from the group of files constituting the “main menu screen” (40).
5). The acquired weather forecast data is embedded in the weather forecast frame on the “main menu screen” and presented on the television (display medium) (406). On the “Main Menu Screen”, the user changes the registration information such as the registration area of the area registration (40
If 7) is not performed, the weather forecast service flow in the receiver ends here (408).

On the other hand, if there is no information on the area registered in the memory (2) (NVRAM) 74 in the confirmation of the area registration in step 403, the browser presents the initial state display on the "main menu screen" (409). In order to enable the user to select a registration area during the initial state display, confirmation of area selection execution is performed in the receiver (41).
0). When the area is selected here, the receiver presents a selectable area, and registers and saves the selected area information in the memory (2) (NVRAM) 74 (411). When the area is registered in the memory (2) (NVRAM) 74 in step 411, the operation in the receiver proceeds to step 405 described above.
The operation is similar to the operation of 406 and 407. If area selection is not performed in step 410, the flow of the weather forecast service ends (408). Step 40
If the registration area is changed in step 7, the operation in the receiver proceeds to step 410, and thereafter the same operation as described above is performed. 4-3. Save / read operation (program guide & notepad display function)

In this service, information introduced in this channel can be registered as a memo in a memo pad.
Here, a program guide and a memo pad display will be described as an example. However, the present invention is not limited to this, and appropriate information on a screen can be stored and read.

FIG. 23 is an explanatory diagram of the program guide & memo pad display function. The memo pad frame 281 and the memo registerable information 282 are separately transmitted by information distributed from a broadcasting company. The receiver 7 receives the information, selects information to be registered by the user from the memo registerable information 282, and stores the memo information 285 in the storage area of the memo pad in the memory (2) (NVRAM) 74. . "Program guide & notepad screen"
When is selected, the memo information 285 registered by the user is entered and displayed in the frame 281 of the memo pad. here,
If the memo information 285 has a keyboard or a function capable of writing characters, the user himself / herself can enter the memo information 285.
5 can be created, stored in the memory (2) (NVRAM) 74, and displayed in the memo pad field of the program guide & memo pad screen.

FIG. 24 shows the main menu, the program guide &
Shows the notepad detail screen. By selecting one program guide & memo pad button on the main menu, the screen is switched to the program guide & memo pad detail screen 280. The program guide 283 is information distributed from a broadcaster, but the memo pad column calls up and displays memo information previously stored in the nonvolatile memory (2) (NVRAM) 74 by the viewer. Memo information 28 stored in the memory (2) (NVRAM) 74
No. 4 can be deleted by selecting a delete button 286 on the right of each memo item on the program guide & memo pad detail screen.

FIG. 25 shows a flowchart of the program guide & memo pad function. When the viewer selects the program guide & memo pad button on the main menu (501), the receiver acquires the program guide & memo pad detailed screen information of the carousel 1 (502). After that, the receiver sets the memory (2) (NVRA
It is determined whether the memo information registered by the viewer in M) 74 exists (503), and if not, the program guide & memo pad detail screen is presented as it is (507). On the other hand, if there is memo information, all memo information is obtained from the memory (2) (NVRAM) 74 (504). If memo information cannot be obtained (50
5) The memo information is acquired again (504), and if it is acquired, the memo information is embedded in the memo pad column of the program guide & memo pad detail screen (506). Thereafter, a program guide & memo pad detail screen is presented (507) and displayed on the TV (508).

4-4. Write Operation (Memo Registration Function) FIG. 26 is an explanatory diagram of memo registration. Here, a memo registration function will be described as an example of the writing operation. This figure shows a main menu, a program guide & notepad detail screen. A bulletin board 311 service is provided on the main menu, and plays a role as a bulletin board by displaying event information and the like. Further, by selecting the memo registration button 312, it is possible to make a memo of the bulletin board information. The memo information registered by the viewer is displayed in the memo pad 314 column of the program guide & memo pad screen 313. If the number of memo information registered in the memory (2) (NVRAM) 74 by the viewer exceeds a specified number, the new memo information is overwritten with the oldest memo information. As another example, it is conceivable to use a method of displaying a message before overwriting, making it impossible to overwrite, and using a method that cannot be registered unless there is a blank area.

FIG. 27 shows a flowchart of the bulletin board service. The viewer views information of the bulletin board service on the main menu (601), and determines whether to register information described on the bulletin board in a memo pad (602). When registering, a memo registration button in the bulletin board service is selected (603), and memo information is acquired (604). Here, it is determined whether the number of memo information registered in the memory (2) (NVRAM) 74 is equal to or less than a specified number (605). If the number is smaller than the specified number, the memo information is stored in a blank area (606). If so, the newest memo information is overwritten on the oldest memo information (607). When the memo information cannot be normally stored, the storing operation is performed again (608). Similarly, for variable services and other services, it is possible to memoly register appropriate information.

4-5. Screen switching operation The service for screen switching will be described. 28 and 29 are explanatory diagrams of screen transition when switching from the basic service to the variable service. A service that allows you to watch basic services for free by dividing the carousel,
A mix of free / paid services and services that allow you to watch variable services for a fee is possible (both are free and sometimes paid), but in general, it takes several seconds to switch from basic services that cross the carousel to variable services. Waiting time occurs. In order to make effective use of the waiting time or to alleviate the stress of the viewer, a switching screen that is displayed when switching from the basic service to the variable service is prepared. At this time, a submenu is prepared as a start screen of the variable service, and the submenu screen is always displayed when switching from the switching screen to the variable service. The viewer can view the variable service by selecting the variable service button 421 on the main menu, but the advertisement 422, the message 423, the character 424, and the like are displayed until the viewer switches. After a few seconds, when the receiver is ready to display the variable service screen, the variable service screen 425 as shown in FIG. 29 is automatically displayed. The graphic memory 77 in the receiver 7
In order to retain the previous data until the next screen data is written from the browser 73, even if the user selects a button at the time of screen switching involving carousel movement, the browser constructs the next screen data and creates the graphic memory 77. There is no change in the display screen until the time of writing to the screen. Therefore, there may be an illusion that the operation has stopped, and in order to avoid this, the above-described screen switching service is effective.

FIG. 30 is a flowchart showing screen transition when switching from the basic service to the variable service. When the viewer selects the variable service from the basic services (701), the receiver acquires the switching screen information of the carousel 1 (702), presents the switching screen information (703), and displays the switching screen on the TV (703). 70
4). In the switching screen information, the receiver is instructed to acquire the sub-menu screen information of the variable service n seconds later.
5) Automatically start acquiring the sub-menu screen information of the variable service of the carousel 2 (706). When the variable service submenu screen information is acquired (70
7), present it (708), and display it on the TV (709).
The switching screen information such as the advertisement 422, the message 423, and the character 424 can be included in the carousel 1, and can be held in the graphic memory 77 or another memory when switching. The number of screens, the screen type, and the like can be appropriately set.

4-6. Other operations Bulletin Service The Bulletin Service on the main menu (see the box of text 5 in FIG. 7) allows breaking news, news, professional baseball information, and the like to be played by telop. In addition to characters, pictograms that can be displayed on a character / graphic plane can also be played with a telop. As a specific example, it is also possible to make the background of the telop and the background of the screen the same color, and to move the pictogram left and right without making the user recognize the telop. The information of the flash report can be updated in a short time cycle.

2. Advertising service viewing sequence The definition of the advertising service in this service is as follows: banner / telop advertisement displayed at the bottom of the screen when viewing each service screen, and details presented by selecting the banner / telop advertisement It is composed of an advertisement (see FIG. 7, text 6, box of image 3). Here, the number of advertisements in the basic service and the number of advertisements in the variable service can be provided as appropriate numbers. Also,
If the detailed advertisement service is not provided, it is also possible to increase the number of banner / telop advertisements and the like.
