(1) First embodiment

(1-1) Overall Configuration

In Fig. 1, reference numeral 1 denotes an information distribution system as a whole, and a distribution center 4 having a program distribution server 2 and a program control server 3 is connected to an internet network 5 as an information transmission network.

As shown in Fig. 2, the program distribution server 2 divides the program information CH1, CH2, CH3, and CH4 for a plurality of channels, that is, the first, second, third, and fourth channels, into a first division time. Unit program data (D1-20, D1-21, ... D1-19), (D2-20, D2-21, ... D2-19), (D3-20, D3-21, ... D3-19) and (D4-20, D4-21, ... D4-19) are stored in the program database 2XA as delivery information INF.

This distribution information is created by the program creation terminal 8 connected to the Internet network 5 and stored in the program database 2XA.

In this embodiment, the program information CH1 to CH4 of the first to fourth channels is 20: 00, 21:00,... The unit program data D1-20 to D4-20, D1-21 to D4-21 starting at 19:00 (this is referred to as "20:00", "21:00", ... "19:00"). D1-19-D4-19 (this is shown by DM-N: M = 1-4, N = 20-19).

As shown in Fig. 3, each unit program data DM-N is divided into program frame content data Dmnp from N hour 00 minutes 00 seconds to N + 1 hour 00 minutes 00 seconds, the second division time being 15 seconds in this case. It is made, including.

Each unit program data Dmnp corresponds to one home page screen. Thus, the unit program data DM-N receives program frame content data Dmnp corresponding to 4 × 60 sheets of home page screens during the first division time of one hour (that is, From N hour 00 minute 00 second to N + 1 hour 00 minute 00 second (N = 20 to 19), every second division time (that is, at 15 second intervals).

Each program frame content data Dmnp is designated by the user terminals 6A, 6B, ... through the Internet network 3 (FIG. 1) using the channel table data CHDAT in FIG. 4 and the time table data TMDAT in FIG. do.

The channel table data CHDAT is " channel number data " (ChNo.) That designates a channel number (first to fourth channels in this embodiment) to which the program information is to be delivered, and " "Date data" (date), "time data" (up to the time (seconds)) indicating the time to deliver the program, and "channel location designation data" (channel URL: Uniform Resource Locator) indicating the storage location of the program information. Has a data structure in which the time channel table data TCDAT having) is arranged in chronological order.

The first row data of the channel table data CHDAT in FIG. 4 is " 1 " (indicating that the first channel is specified), and " date data " is designated " 20001011 " (October 11, 2000). ), &Quot; time data " is " 120000 " (which indicates that 12: 00: 00 is specified), and " channel information location designation data " is " http: //www.xxx.co.jp/ch1/ timetab1e.dat ”(the location of the program is the" http://www.xxxx.co.jp "server, that is, the program delivery server 2, and the timetable of the first channel" ch1 / timetable.dat " Data).

By doing so, the user terminals 6A, 6B, ... transmit the data of the first row of the channel table data CHDAT in Fig. 4 to the Internet network 5, thereby giving the server number "http://www.xxxx.co.jp". The program information of the first channel for 1 hour from 12: 00: 00 seconds on October 11, 2000 from the server (that is, the program distribution server 2). Can be specified according to the specification of the.

The same applies to data in other rows of the channel table data CHDAT in FIG. 4.

With respect to the channel table data CHDAT in Fig. 4, the time table data "timetable." Contained in the "channel information location designation data". dat " each has time table data TMDAT having the configuration as shown in FIG.

The time table data TMDAT has frame information specifying data FRDAT for specifying frame information to be sequentially displayed for each of the second dividing time 15 seconds during the time of the first dividing time (one hour) as data for each row.

First, second,... The frame information designation data FRDAT of the line indicates "frame number data" (Kno: ("1,", "2,", ...)) representing a frame number for one hour, and a time for displaying the frame information. A "frame" indicating a place where "frame display time data" (times "120000," "120015," ...) and corresponding frame information (including frame information of a program image and frame information of an advertisement image) are stored. Information location designation data "(display URL" http://www.xxxx.co.jp/1./ "," http://www.xxxx.co.jp/ch1/2./ ",…), "Advertisement format data" ("html", "cab", "paz") indicating an image creation method of the frame information, and "advertisement" indicating an advertisement server storing the advertisement when viewing only the advertisement image after the end of the program. Link designation data "CMDAT (",, ") and the table in the X and Y directions of the corresponding frame. The display width designation data ("100, 50,", "100, 50, ...") indicating the number of hour dots and the display type designation data ("1," in this embodiment) indicate the type of the display image. An image is shown, "2," represents a creative image (for example, animation), and "3," represents a moving image accompanied by audio.

Here, the image format data "html" represents HTML (HyperText Markup Language: an image created by a hypertext standard language protocol (an image not subjected to special image processing)), and "paz" represents an image created by a moving image division method. In addition, "cab" represents an image created by an image compression method (e.g. MPEG: Moving Picture Experts Group (international standard for media integrated video compression)).

By doing so, in FIG. 5, for example, the first row frame information designation data FRDAT has " 1 " (representing the first frame) as the frame number data, and then " 120000, " 00 minutes 00 seconds), and continue to display "http: // www." As frame information addressing data. xxxx.co.jp/ch1/1.html/ "(in this embodiment, the normal screen of the first channel" CH1 "from the server designation number of the program distribution server 2 (in the case of the program frame screen and ), And the frame is not an ad server link because there is no data between the commers (",,") (commercially available). ), And have "100, 50," (indicated that the display width is 100 dots in the X direction and 50 dots in the Y direction) as the display width specification data, and then " 1, ”(the first display example, i.e., what should be displayed on the normal screen).

The same applies to the frame information designation data FRDAT of other rows of the time table data TMDAT in FIG. 5.

Here, when the advertisement link designation data is added when the frame screen is an advertisement, the user terminal 6A, 6B, ... saves the advertisement link designation data at the time of program transmission, so that after the end of the program information, By using this, it is possible to specify to acquire screen display information identical to the advertisement screen used as part of the program information from the advertisement servers 7A, 7B, ... (FIG. 1).

In the 100th frame of the time table data TMDAT in Fig. 5, when the frame number data is "100," on the advertisement display screen, and the frame display time data is "121530," (representing 12:15:30), the server The number is `` http: // www. It has advertisement display screen information of "ch1 / 100.html" of the program distribution server 2 which is xxxx.co.jp/ ", and it displays this advertisement display screen at the server number" http: // www. yyyy.co.jp/ "can be acquired from the advertisement servers 7A, 7B, ... (FIG. 1), and this is the size of display width designation data" 10, 50, "and display type designation data" 1, " Specify the data to be displayed on the (normal screen).

In this way, in the case of Fig. 5, the advertisement display screens can be distributed to the user terminals 6A, 6B, ... for 15 seconds from 12:15:30 between the program screens.

(1-2) Distribution of Program Information

In the information delivery system 1 of FIG. 1, the distribution center 4 distributes control information including reference time information to user terminals 6A, 6B, ..., which are intended to receive the distribution of program information, in advance. On the basis of the reference time information, a plurality of user terminals 6A, 6B, ... are simultaneously delivered with the same program information.

(1-2-1) Distribution of control information

When the user terminals 6A, 6B, ... are registered in the information delivery system 1, they store a delivery program (this is called an "active view program") and receive program information from the delivery center 4. , Start the active view program.

At this time, as shown in Fig. 6, the user terminals 6A, 6B, ... transmit the terminal information D1 including the terminal ID, personal information, etc. to the program control server 3 of the distribution center 4, The program control server 3 transmits the reference time information to the user terminals 6A, 6B, ... in response to this.

As a result, the user terminals 6A, 6B, ... that have received the reference time information D2 match the time between the program control servers 3, and accordingly the plurality of user terminals 6A, 6B,... Each is in a state capable of synchronously operating with the distribution center 4 based on the reference time independently.

In this state, the user terminals 6A, 6B, ... receive the distribution of the channel table data CHDAT (Fig. 4) corresponding to all the program data included in the distribution information of Fig. 2, and save it.

In this way, the user terminals 6A, 6B, ... are unit program data of all the times of the first to fourth channels (that is, from 20:00 to 19:00) stored in the program distribution server 2. It becomes a state which can specify DM-N (FIG. 3). In this state, the program selection switch SW1 as shown in Fig. 7 is displayed on the display of the user terminals 6A, 6B, ..., and the current time (" 19: 36: 59 ": indicated as the reference time) is " TIME "column and the channel which wants to be delivered by the 1st-4th channel switch SW1A at the present time can be designated (the display of the designated content" CH1 news "appears).

When the display start switch SW1B is operated in such a state, the screen of the delivery information can be displayed by opening the screen on the display.

The display of this program selection switch SW1 is turned off from the display of the display by operating the hide button SW1C, and can be returned by operating the display return button SW2 provided in the task bar as shown in FIG.

In this embodiment, the program selection switch SW1 is provided with a reservation button SW1D, and when this is operated, the program selection switch SW3 of the switch arrangement corresponding to the unit program data DM-N of FIG. On the display of (6A, 6B, ...), the program delivery server 2 distributes the desired program (i.e., 20 to 19 o'clock for the first to fourth channels) by operating one of the switches. Program to start the system) can be reserved.

(1-2-2) Distribution of Program Information

When the user terminal 6A, 6B, ... wants to receive a program desired by the user, the channel switch SW1A of the program selection switch SW1 on the display of the user terminal 6A, 6B, ... is operated.

In this state, when the display start switch SW1B of the user terminals 6A, 6B, ... is operated, the frame information designation data of the time table data TMDAT distributed by the program distribution server 2 to the user terminals 6A, 6B, ... We return FMDAT sequentially.

In this way, on the displays of the user terminals 6A, 6B, ..., the frame images displayed by the respective frame display data are sequentially displayed while synchronizing with the reference time.

If the user designates a program of "October 11, 2000 12: 00: 00" for the "first" channel as the distribution request information, the user terminals 6A, 6B,... By sending the row time channel table data TCDAT to the program control server 3 (FIG. 6), receiving the delivery of the corresponding time table data TMDAT (FIG. 5), the frame information designation data FRDAT for each row at the time of the frame delivery time. Is sent to the program distribution server 2 (FIG. 6).

In this way, the user terminals 6A, 6B, ... designate the program control server 3 by the channel information designation data included in the channel table data CHDAT distributed from the program control server 3 as shown in FIG. Receive the time table data TMDAT, and the frame image designation data FRDAT included in the time table data TMDAT is used to transfer the frame image data and the advertisement image data and the advertisement link specifying data CMDAT from the program distribution server 2 into the image information. URL1, URL2,... It is betrayed as (Figure 6).

Here, when the time table data TMDAT does not have the advertisement link designation data CMDAT data (that is, ","), the user terminals 6A, 6B, ... are images that are not advertisements from the program distribution server 2. Receive data distribution.

On the other hand, when display data including the advertisement link designation data CMDAT as the time table data TMDAT arrives, the user terminals 6A, 6B, ... display the advertisement image on the display by the advertisement display data, and the corresponding advertisement is displayed. By storing the link designation data CMDAT, the advertisement information can be read from the designated advertisement servers 7A, 7B, ... to the user terminals 6A, 6B, ... via the Internet network 5 after the end of the program.

In the case of Fig. 5, the frame information designation data FRDAT whose frame program Kno is "100" is the advertisement link designation data CMDAT, which is an advertisement server (7A, 7B, ...) of "http://www.yyyy.co.jp,". Is specified.

In this way, the user terminal replaces the program information specified by the user by the program selection switch SW1 (Fig. 7) by sequentially cutting the program information every 15 seconds according to the time specified by the frame display time data of the time table data TMDAT. It can display on the display of (6A, 6B, ...).

Therefore, the user can see the image (which is a program image and an advertisement image inserted therebetween (for example, as shown in FIG. 11)) sequentially changing at 15-second intervals. Can be received through the Internet network (5).

In this case, as part of the image that changes at intervals of 15 seconds, as shown in FIG. 11, the advertisement image DP1 displayed on the front of the display screen 16 of the user terminals 6A, 6B, ... can be received. Therefore, the user can read the contents of the advertisement (for example, detailed information on the product to be purchased).

In addition, the program data distributed to the user terminals 6A, 6B, ... through the Internet network 5 can be transmitted to a plurality of user terminals 6A, 6B, ... that have simultaneously or simultaneously requested delivery by the reference time. In this way, the user terminals 6A, 6B, ... distributed from the distribution center 4 to the area in which the Internet network 5 is installed, as in the case of a normal broadcast program, have the same program at the same time, and therefore, a large number of programs. Can be provided as

By doing this, one unit program data DM-N selected by the program selection switch SW1 (Fig. 7) is transferred to the plurality of user terminals 6A, 6B, ... by the corresponding time channel table data TCDAT. At the same time and sequentially changing image information URL1, URL2,... Although it can be distributed as shown in FIG. D, if the user selects another program during the delivery of the single unit program data DM-N or at the end of delivery, the user terminals 6A, 6B, ...) and the time channel table data TCDAT transmitted to the program control server 3 is converted to TCDAT-1, so that the frame information designation data FADAT is switched to FADAT-1, which is distributed from the program distribution server 2 accordingly. The program screen data and the advertisement screen data are changed, so that the changed image information URL11, URL12,... Are changed to the user terminals 6A, 6B,... Can betray.

When the user terminals 6A, 6B, ... that have received the distribution of program information send the termination information to the Internet network 5, the program controller server 3 ends the delivery operation of the program.

(1-3) Preservation of advertisement link designation data

The user terminals 6A, 6B, ... are provided with screen saving buttons (so-called book mark buttons: 17) on the display screen 16 as shown in FIG. It is configured to preserve the screen having a.

That is, as described above with reference to FIGS. 1 to 11, the advertisement screen DPI can be displayed on the display screen 16 as shown in FIG. 12 by the time table data TMDAT into which the advertisement link specifying data CMDAT is inserted.

When the user operates the screen save button 17 while displaying such an advertisement screen DPI on the display screen 16, the advertisement link specifying data CMDAT is stored in the memory of the user terminals 6A, 6B,... .

This stored advertisement link designation data CMDAT is displayed on the display screen 16 of the user terminals 6A, 6B, ... after the program is finished, in the state of displaying the program selection switch SW1 as shown in Fig. 13. Designated data ", http // iKenchiku. net, "as the first advertisement saved, and the advertisement link designation data", http // alpha. international., ”as the second advertisement having the same name.

In this state, when the user designates and operates the display of either of the advertisement designation data CMDAT, the user terminals 6A, 6B,... Are designated by the advertisement server 7A, 7B, …)

In this way, the advertisement screens provided in the advertisement servers 7A, 7B, ... can be presented to the user in the user terminals 6A, 6B, ... designated through the Internet network 5.

In this way, the user can always view the interesting advertisement screen at any time, without limitation, at the end of the program.

(1-4) Method of receiving program information of user terminal

When the program distribution server 2 of the distribution center 4 (FIG. 1) distributes program information to the user terminals 6A, 6B, ... via the Internet network 5, the user terminals 6A, 6B, ...) Is configured to switch in the program delivery server 2 so that delivery can be performed by the sequential reception method shown in FIG. 14 or the overlay reception method shown in FIG.

In Fig. 14, the user terminals 6A, 6B, ... are provided with program information IF1, IF2,... From the Internet network 5. As the reception display unit 12 for receiving the data, a pair of reception memory units 12A and 12B which alternately receive are used, and the program information IF1, IF2,... Is received in the first receiving memory section 12A, the program information already received and completed in the second receiving memory 12B is displayed.

After that, when the reception of the program information in the first receiving memory section 12A is finished and the image is completed, the program information coming from the Internet network 5 is switched to the state in which the second receiving memory section 12B is received. In addition, the program information received by the first receiving memory section 12A is displayed.

In this way, since the storage capacity of the receiving memory 12 of the user terminals 6A, 6B, ... is large, a relatively large file such as a moving picture or the like can easily display the user terminals 6A, 6B,... In addition to controllability, seamless images can be displayed on the display.

By the way, in the case where it is desired to receive the delivery of voice-added program delivery data in which voice is output while reading, there is a fear that the program information arrives at the timing at which sound starts to be output while the program information is read in the receiving memory unit on the receiving side. have.

In this case, when transferring from the program delivery server 2 to the reception memory 12A or 12B, the data of the program information is compressed and distributed.

As shown in FIG. 5, the frame information designation data "cab" which shows image compression data is used for program information compressed in this way as shown in FIG.

If it is not necessary, the program information is transmitted without specifying compression as shown in FIG.

That is, in the case of Fig. 5, the frame information designation data having the frame numbers "4" to "6" adds category data "cab" indicating "image compression and creation". Then, the type data "html" is added to the frame information designation data in the "send without compression processing" program information.

In this way, when program information compressed in one receiving memory unit is written from the Internet network 5 in the receiving memory 12, all of this is input into the user terminals 6A, 6B, ... to perform the decompression process. As a result, since the sound starts to come out at the timing of returning to the original program information, the problem of the sound coming out first can be effectively solved.

According to the sequential reception method of FIG. 14, since the reception display unit 12 of the user terminals 6A, 6B, ... can perform a reception operation with sufficient margin, the program information is sent to the user terminals 6A, 6B,... Input can be made without interruption.

By the way, by using the sequential receiving method of FIG. 14, all the program information distributed from the program distribution server 2 to the user terminals 6A, 6B, ... can be received in the receiving memory 12 without being in an insufficient state. For example, in order to protect copyright, it is necessary to allow program information to be erased without leaving the program information once it is received by the user terminals 6A, 6B, ....

In this case, the program distribution server 2 provides a pair of first and second transmission memory sections 11A and 11B as the transmission memory 11, as shown in Fig. 15, and the first and second transmission memories. Program information IF1, IF2, IF3,... Record duplicates in turn.

The program information of the first and second transmission display units 11A and 11B of the transmission memory 11 is transferred to the first and second reception memory units 12A and 12A of the reception memory 12 of the user terminals 6A, 6B,. 12B) to receive directly through the Internet network 5.

In this way, only two pieces of program information distributed from the transmission memory 11 of the program delivery server 2 remain in the first and second reception memory units 12A and 12B.

Therefore, according to the configuration of FIG. 15, program information is input into the user terminals 6A, 6B, ... from one of the receiving memory units 12A and 12B of the receiving display unit 12. In this state, the data of the other receiving memory section is in a state where new program information is written in the previous program information in the corresponding transmitting memory section, so that the remaining program information is unnecessarily inputted to the user terminals 6A, 6B,... It is possible to effectively avoid the possibility of causing a problem, and by doing so, it is possible to realize a program information distribution system in which copyright protection has been processed.

Depending on the number of (6EA, 6EB, 6EC), the display time of the image on the display is greatly delayed (the delay is greatly delayed from the point of time captured by the television camera 21A), but the information delivery system 1X of the embodiment of FIG. According to the above, this problem can be effectively solved.

(5) Fifth Embodiment

(5-1) Overall structure

In the case of the fifth embodiment, the information delivery system 1 has the same schematic configuration as described above with respect to FIG. 1 and uses the configuration of FIG. 23 as the user terminals 6A, 6B,...

In the user terminals 6A, 6B, ..., the CPU (central processing unit) 31 processes the user terminals 6A, 6B, ... by the startup program memory 33 configured by the ROM via the bus 32. In addition to activating the operation, a program in the program memory 34 made of RAM using a hard disk is executed using the temporary storage memory 35 made of RAM. Accordingly, in FIG. 24, in which the corresponding parts to FIG. 6 are denoted by the same reference numerals, the user terminals 6A, 6B, ... are associated with the channel table data CHDAT and the time table data TMDAT between the program controller servers 3. In addition to executing the transfer process, information transfer process relating to the frame designation data FRDAT is executed between the program delivery server 2.

The transfer of data between the user terminals 6A, 6B, ..., the program distribution server 2 and the program controller server 3 is performed by the CPU 31 controlling the communication interface 36 via the bus 32. After inputting data transmitted from the Internet network 5 to the temporary storage memory 35 and performing internal processing on the data, the GUI is configured using the graphic interface 37 through the bus 32. Is displayed on the display 38 and stored in the external storage device 39 via the bus 32 as necessary.

The user of the user terminals 6A, 6B, ... inputs the designated information by operating the mouse 41 as data input means via the mouse interface 40 connected to the bus 32 with the cursor on the display 38. As a result, the CPU 31 executes internal processing of the data and transmits the communication information to the Internet network 5 via the communication interface 36.

(5-2) Program start processing procedure

At the time of program start of the user terminals 6A, 6B, ..., the CPU 31 starts the program memory 34 in accordance with the program of the start program memory 33 and executes the program start processing procedure RT0 shown in FIG. do.

The CPU 31 first executes a process of transmitting the terminal authentication ID and password to the program controller server 3 as the terminal information D1 (Fig. 24) when the user inputs the terminal authentication ID and password in step SP1.

Subsequently, the CPU 31 checks whether it has connected with the program controller server 3 in step SP2, and when a negative result is obtained, this means, for example, that there is an inconsistency in the ID password, and the CPU 31 at this time After displaying an error on the display 38 in step SP3, the process returns to the above-described step SP1 to execute input processing of the terminal authentication ID and password again.

If a positive result is obtained in step SP2, the CPU 31 proceeds to step SP4 to display the control panel display DIP1 on the display screen 38A of the display 38 as shown in FIG.

The control panel display DIP1 displays the program display unit DP1 displaying the distributed program image on the upper left side, and selects a channel to be distributed on the right side thereof. 12 channels can be selected).

In this way, the user can display the selected program on the program display unit DP1 by selecting and operating one of the channel switches of the channel selection switch unit DP2 while the control panel display DIP1 is displayed.

In this embodiment, the control panel display DIP1 is assigned to the lower portion of the program display unit DP1, the reserved program table switch DP3 (operated when making a program reservation), and the channel group switch DP4 (each channel of the channel selector switch DP2). Operation when selecting one of a group from a plurality of channel groups), language switching switch DP5 (operation when selecting a language used in a program), and country switching switch DP6 (corresponding to user terminals 6A, 6B, ...). A transmission network to be connected, for example, a selective operation on a base station of the Internet network 5) is provided.

In addition, the display end switch DP7 is provided in the lower portion of the control panel display DIP1, and the display of the control panel display DIP1 is closed by operating this.

Thereafter, the CPU 31 proceeds to step SP5 to obtain the reference time information D2 and the channel table data CHDAT and other information from the program control server 3, and temporarily through the communication interface 36 and the bus 32. Input is made to the channel table data memory 35A of the corresponding memory 35.

In this way, the user terminals 6A, 6B, ... transmit the terminal information D1 from the user terminals 6A, 6B, ... to the program control server 3 in FIG. The outside information has been delivered.

In this state, the CPU 31 proceeds to step SP6 and the display end switch DP7 is operated to maintain the program start state until delivery ends. In this state, the user of the user terminals 6A, 6B, ... executes the program when the user selects and selects a program stored in the program memory 34 by operating a switch on the control panel display DIP1. The processing can be performed outside.

If a positive result is obtained in step SP6, this means that the user has terminated delivery of the program by operating the display end switch DP7, at which time the CPU 31 proceeds to step SP7 and terminates information to the program control server 3. D3 is transmitted (Fig. 24), and the program start processing procedure RT0 is terminated in step SP8.

(5-3) X channel button processing sequence

In step SP6 of the program start processing sequence RT0, the CPU 31 allows the user of the user terminals 6A, 6B, ... to select one channel button from the channel selection switch unit DP2 of the control panel display DIP1 (this is called the "X channel button"). ), The CPU 31 executes the X channel button processing procedure RT1 shown in FIG.

Upon entering the X channel button processing sequence RT1, the CPU 31 transmits the request information of the time channel table data TCDAT (Fig. 4) of the X channel at the current time to the program control server 3 in step SP1, and the program control server. The time table data TMDAT (FIG. 5) of the X channel of the present time is obtained from (3) and input to the time table data memory 35B provided in the temporary storage memory 35 via the communication interface 36 and the bus 32. FIG. .

The CPU 31 then proceeds to the next step SP11 to determine whether the current state is before the start of display of the moving image data. The judgment of the CPU 31 determines whether the user of the user terminals 6A, 6B, ... is going to see the program of the moving picture from the middle, and when the positive result is obtained, the CPU 31 proceeds to step SP12.

In the case of this embodiment, the user terminals 6A, 6B, ... can receive the normal image "html", the compressed image "cab", and the moving image "paz" as the type of image as described above with respect to FIG. In the moving picture "paz", when the moving picture is to be viewed from the middle, the CPU 31 obtains a negative result in step SP11. On the other hand, when viewing other images, that is, normal image "html", compressed image "cab", and moving image "paz" from the beginning, the CPU 31 obtains an affirmative result in step SP11.

Upon shifting to step SP12, the CPU 31 transfers and starts the time table data TMDAT to the communication interrupt timer 45 and the display interrupt timer 46, and starts the display. One program display panel DIP2 is displayed.

As described above with reference to Figs. 14 and 15, the program display panel DIP2 alternately forms two display screens, namely, first and second browser screens BR1 and BR2, by means of the graphic interface 37, of which completion is made. One displayed screen is displayed on the program display unit DP1 (the other screen gradually forms an image each time the image data arrives, and when completed, switches it to the program display unit DP1 for display).

In the case of Fig. 28, the voice volume VL is displayed on the lower right portion of the program display panel DIP2, so that the user can adjust the voice using this.

In the following step SP14, the CPU 31 displays the standby image stored in advance in the standby image memory 47 on the program display unit DP1 for a predetermined time (for example, 15 seconds).

The process of this step SP14 is performed after the user operates the X channel button, from the program delivery server 2 until the program data is provided in the delivery image data memory 35C of the temporary recording memory 35. Since it takes time corresponding to the delay, in order not to give anxiety to the user, a guidance display such as "Please wait" or an advertisement image as described above with reference to Figs. Display.

Thereafter, the CPU 31 ends the X channel button processing sequence RT1 in step SP15.

On the other hand, if a negative result is obtained in step SP11, this means that the X channel button is operated while the moving picture data is being displayed, at which time the CPU 31 starts step SP16 in order to start displaying the image from the middle of the moving picture. To SP21.

In general, a large amount of data needs to be transmitted in comparison with a still image. Therefore, when a moving image "paz" is transmitted as shown by frame number Kno = 7 of FIG. The moving picture segmentation data divided into the image portions of the image is prepared in advance in the program delivery server 2.

That is, as shown in Fig. 29A, when the frame information specifying data FRDAT (Fig. 5) having frame number Kno = 7 is designated, as shown in Fig. 29B, the frame of the first channel ch1 is shown. One moving image program "ch1 / 7." paz "(e.g., 10 minutes of moving image) is divided into 10 image partial data VDX (e.g., 1 minute of image data), and each image partial data VDX is represented as shown in FIG. The first to tenth moving picture divided frame data F1 to F10 are divided into a series of moving picture divided data "F1, F2,... &Quot; F10 " is stored in the program distribution server 2 beforehand.

Here, one moving picture program "ch1 / 7. 1" is included in the first moving picture divided frame data F1. A moving picture header HD having management information indicating the configuration of ten image partial data VDX of "paz" is provided as head information, and accordingly the moving picture program "ch1 / 7. paz " information, for example, the number, size, data format, display time, etc. of the image partial data VDX, and accordingly acquires the moving picture header HD of the first moving picture division frame data F1, ch1 / 7. paz 'data structure.

Such moving picture divided frame data F1, F2,... When F10 is set to the start time 12: 1: 30 as the frame information designation data FRDAT of the seventh frame (Kno = 7), the start time is 12: 1: 30 as shown in Fig. 30A. At the time t = tx after the second, when the X channel button is operated, as shown in FIGS. 30B to 30D, the user terminals 6A, 6B,... The processing of steps SP16 to SP21 is executed to display only the frame data F6 to F10 after tx.

In other words, when the negative result is obtained in step SP11, the CPU 31 sets the sequence of moving picture segmentation data F1 to F2,... After reading the attribute file information [PazInf] relating to F10 from the program control server 3 to the distributed image data memory 35C as the time table data TMDAT, the operation time TX of the X-channel button in step SP17 (Fig. 30 (A) )) And the moving picture segmentation frame data F6 to be read from the reading time point t = t0 of the moving picture segmentation data file, and accordingly the moving picture segmentation frame starting from the time point t = t6 after the operation time point t = tx of the X channel button. It is determined whether the data F6, F7, F8, F9, F10 should be displayed on the display 38.

The attribute file information "PazInf" is a frame information (Name = 7), an image format (Ex = mpg (indicated to be a compressed image)), data size (Size = 3000000 (indicated 3000000 bytes)), and number of divisions (Count). = 10 (includes ten moving picture divided frame data F1 to F10).

In addition, each frame data F1, F2,... , The start address (Start = 0, Start = 300000, ..., Start = 2700000 (indicating the starting byte position)) and the data size (Size = 300000, Size = 300000, ... Size = 300000 ( 300000 bytes)) and time required (Time = 6000, Time = 6000, ..., Time = 6000 (indicated 60 seconds)).

Then, the CPU 31 displays the standby image of the standby image memory 47 on the program display unit DP1 of the display 38 in step SP18, and subsequently reads the attribute file read into the delivery image data memory 35C in step SP19. From "PazInf", the moving picture empty file FILEX as shown in Fig. 30C is created in the moving picture division memory 49 (Fig. 23).

This moving picture empty file FILEX has a header HD of moving picture data already distributed at the operation time point t = tx of the X channel button, and an empty file division frame 0X * 1X * 2X corresponding to moving picture division frame data F1 to F10. A moving image empty file FILEX having 10X is formed in the delivered image data memory 35C.

In this way, as shown in Fig. 30D, a memory area capable of inputting frame data F6 to F10 distributed after the X channel button operation time point t = tx to the empty file division frames 6X to 10X is shown. It forms in the delivery image data memory 35C. Subsequently, the CPU 31 creates a playback start command file [7, smi] during the moving picture as shown next in step SP20.

(7, smi)

<smil>

<body>

<ref clip-being = "300.os" src = "7.mpg"

</ body>

</ smi1>

Where <smil> is the file name, <body> is the body, and <ref clip-being = "300.os" = "7.mpg"> is an MPEG compressed file called 7.mpg that plays at 300 seconds. The statements </ body> and </ smil> indicate termination.

Thereafter, the CPU 31 proceeds to step SP21 to transfer a time table to the reproduction display interrupt timer 46C during the moving picture of the communication interrupt timer 45 and the display interrupt timer 46 to start the timer. In step SP14 and step SP15, the corresponding X-channel processing sequence RT1 is terminated.

(5-4) Image information reading processing procedure

In this way, when the communication interrupt timer 45 is activated in steps SP12 and SP21 of the X-channel button processing procedure RT1 in FIG. 27, the CPU 31 generates an interrupt data each time the communication interrupt timer 45 generates interrupt data. The image information reading processing procedure RT2 is executed.

Upon entering the image information reading processing sequence RT2, the CPU 31 judges whether there is data to be read based on the distributed time table read in the distributed image data memory 35C in step SP32, and when a positive result is obtained, the step In SP33, it is checked whether the attribute file information "PazInf" (FIG. 29 (D)) is included in the frame information designation data FRDAT (FIG. 5) of the time table.

If a negative result is obtained here, this indicates that the image of the frame information designation data FRDAT is a normal image &quot; html &quot;, and at this time, the CPU 31 proceeds to step SP34, and the image information URL1, URL2,… Is downloaded to the user terminals 6A, 6B,...

Where image information URL1, URL2,... Downloading is performed using the transfer protocol FTP.

Next, in step SP35, the CPU 31 saves the downloaded image information in the delivery image data memory 35C, proceeds to step SP36, determines whether the file currently being read is finished, and when a positive result is obtained. After stopping the communication interrupt timer 45 in step SP37, the corresponding image information reading processing procedure RT2 is ended in step SP38.

On the other hand, if a negative result is obtained in step SP36, this means that there is a possibility that time table information may come to the file currently being read, and then to the time table data memory 35B, at which time the CPU 31 performs the step SP37. In step SP38, the image information reading processing sequence RT2 is terminated without processing.

Thereafter, the CPU 31 processes the steps SP32-SP33-SP34-SP35-SP36-SP37-SP38 each time interrupt data is generated in the communication interrupt timer 45, thereby reading the time table read in the time table data memory 35B. The process of receiving delivery of sequential image information to the frame information designation data FRDAT of the data TMDAT is executed.

Then, when the data to be read in the time table distributed to the time table data memory 35C is lost, as the negative result is obtained in step SP32, the CPU 31 proceeds to step SP36.

The above is the processing in the case where the time table data for the normal image is distributed to the time table data memory 35B. However, in the case of a moving image, the positive result is obtained in step SP33 described above, and the attribute file &quot; PazInf &quot; ", The CPU 31 proceeds to step SP40 and downloads the attribute file information" PazInf "from the program distribution server 2 to the distribution image data memory 35C. In addition, in the next step SP41, the divided file included in the attribute file information "PazInf" is additionally held in the delivery image data memory 35C.

In this way, when the time table distributed to the time table data memory 35B includes a moving image split file including the attribute file information "PazInf", all the split files contained in the attribute file information "PazInf" are sequentially delivered. By sequentially reading into the image data memory 53C, a state additionally retained together with other image information of the time table is obtained.

In this way, after the downloading of the moving picture split file of the time table is completed, the CPU 31 returns to step SP31 described above, and other frame information designation data included in the time table held in the time table data memory 35B. Repeat the process for FRDAT. When a negative result is obtained in step SP32, this transfers the image information for all the frame information designation data FRDAT (including a normal image and a moving image divided image) held in the timetable data memory 35B to a distributed image data memory ( 35C), which means that the CPU 31 ends the corresponding image information reading processing sequence RT2 in step SP38 via steps SP36 and SP37.

(5-5) Normal playback display timer processing procedure

Subsequently, when the normal playback display interrupt timer 46A starts in step SP12 of the X-channel button processing procedure RT1 in FIG. 27, whenever the normal playback display interrupt timer 46A generates interrupt data, the CPU 31 ) Executes the normal playback display interrupt timer processing procedure RT3 in FIG.

Upon entering the normal playback display interrupt timer processing sequence RT3, the CPU 31 determines whether the waiting time has elapsed in step SP41, and if the waiting time has not elapsed, returns to the above-described step SP41 and waits for the elapse of the waiting time. do.

After the waiting time has elapsed, the CPU 31 proceeds to step SP43 to determine whether there is distributed image data in the delivered image data memory 35C, and when a positive result is obtained, the process proceeds to step SP44 to coincide with the current time. It is determined whether there is image data of the display time.

If a positive result is obtained here, this means that the image data downloaded from the program distribution server 2 is stored in the distribution image data memory 35C at the time point tx (Fig. 30 (A)) when the user operates the X channel button. In this case, the CPU 31 proceeds to step SP45, indicating that the type of the image data is "html" image (which indicates that it is a normal frame information image) or "cab" image (MPEG compressed image). Is present, or is a "paz" image (indicating that it is a moving image divided image).

When the CPU 31 determines that the normal image "html" is found here, the CPU 31 proceeds to step SP46 to transfer the image data to the graphic interface 37 to form an image of the image data.

In the case of this embodiment, the graphic interface 37 is configured to alternately form two images (this is called first and second browser images) as described above with reference to Figs. 14 and 15, and the CPU 31 Determines whether it is the first browser image or the second browser image currently formed in the next step SP47.

If a determination result of the first browser image is obtained here, the CPU 31 proceeds to step SP48, reads the image data into the first browser, displays the second browser image in the next step SP49, and then the next step. Go to SP50. On the other hand, when the determination result of the second browser image is obtained in step SP47, the CPU 31 proceeds to step SP51 to read the image data into the second browser, and displays the first browser image in step SP52. Go to SP50.

In this way, the CPU 31 alternately displays the image data transmitted from the normal playback display interrupt timer 46A using the first and second browsers of the graphic interface 37 as the first or second browser images ( Display on the display screen 38) (FIG. 28), and then, in step SP50, the displayed image data is erased by the normal playback display interrupt timer 46A, and the normal playback display interrupt timer processing procedure RT3 ends in step SP57. do.

In this way, the CPU 31, whenever there is image data in the normal playback display interrupt timer 46A of the display interrupt timer 46, whenever the normal playback display interrupt tire 46A generates interrupt data, step SP43-. By repeating the process of SP44-SP45-SP46-SP47- (SP48, SP49 or SP51, SP52) -SP50-SP57, all normal image data "html" is displayed on the display screen 38A of the display 38, The displayed image data is erased by the normal reproduction display interrupt timer 46A.

On the other hand, when it is judged that the image data received by the display interrupt timer 46 in step SP45 described above is a compressed image "cab", the CPU 31 decompresses the compressed image in step SP55, and the normal image data and the like. The same image data is converted.

After converting the compressed image "cab" into image data similar to the normal image data in this manner, the CPU 31 proceeds to step SP46 described above, and the same loop as described above with respect to the normal image "html" is described below. Through this, the decompressed image is displayed on the display screen 38A of the display 38, and the processing for erasing the displayed image data from the normal playback display interrupt tire 46A is executed.

On the other hand, when the CPU 31 obtains the determination result that the image to be processed is the moving image "paz" in step SP45 described above, the CPU 31 proceeds to step SP56, where the normal playback display interrupt timer 46A is obtained. Each time the moving picture normal playback display interrupt timer 46B generates interrupt data after stopping the operation of the moving picture and starting the moving picture normal playback display interrupt timer 46B, the moving picture normal playback display interrupt shown in FIG. The timer processing sequence RT4 is executed, and after that, the normal playback display interrupt timer processing sequence RT3 is terminated in step SP57.

On the other hand, if a negative result is obtained in the above-described step SP43, this means that all of the image data of the delivered image data memory 35C has been displayed, and at this time, the CPU 31 performs the program of the display 38 in the step SP58. After closing the display panel DIP2 (FIG. 28) and passing the termination information D3 indicating the operation status to the program control server 3 in step SP59 (FIG. 24), the interrupt timer processing procedure RT3 for the normal playback display in step SP57. To exit.

In addition, when a negative result is obtained in the above-described step SP44, this means that even if image data remains in the normal playback display interrupt timer 46A, there is no need to display it, and at this time, the CPU 31 The process proceeds to step SP58 described above and executes a process of terminating the normal playback display interrupt timer processing procedure RT3.

(5-6) Interrupt timer processing procedure for moving picture normal playback display

In Fig. 33, when the interrupt timer processing procedure RT4 for moving picture normal reproduction is entered, the CPU 31 determines whether the attribute file information "PazInf" exists in the image data of the delivery image memory 35C in step SP61.

If an affirmative result is obtained here, this means that the image data is moving picture divided image data, and at this time, the CPU 31 proceeds to step SP62 to calculate the total capacity of the image data from the attribute file information, As described above with respect to 30 (A) to (C), a moving picture empty file FILEX corresponding to the frame data F1 to F10 is formed in the moving picture division memory 49.

Subsequently, the CPU 31 determines whether there is divided image data in the delivered image data memory 35C in the next step SP64.

If a positive result is obtained here, the CPU 31 proceeds to step SP65 to overwrite the interrupt image data with the moving picture empty file FILEX (Fig. 30 (C)) of the moving picture division memory 49.

Subsequently, the CPU 31 judges whether the divided image data to be processed first is the first divided image data of the moving image empty file FILEX, and when a positive result is obtained, the CPU 31 performs the divided image overwriting the moving image empty file FILEX in step SP68. By sequentially transmitting to the graphic interface 37, playback of the moving image is started, and the processing proceeds to step SP70 described above.

In this case, the graphic interface 37 displays a moving image on the program display unit DP1 by forming a moving image on either the first or second browser screen BR1 or BR2 (FIG. 28).

The CPU 31 then executes second, third, ... overwriting the moving image empty file FILEX. As a result of performing the reproduction processing of the moving image on the divided images, and as a result a negative result is obtained in step SP67 (at the timing of reproducing the second, third, ... divided files), the CPU 31 performs the step A negative result is obtained at SP67, and the process proceeds to step SP69, in which the header data HD overwritten on the moving picture empty file FILEX and the moving picture data portion already displayed on the display 38 are erased one after another.

In this way, since the header data and the image data of the displayed moving image can be erased in the moving image normal reproduction display interrupt timer 46B, the security of the delivered moving image can be maintained.

After the reproduction of all the divided moving picture data written in the moving picture empty file FILEX is completed, a negative result is obtained in step SP64. In step SP70, the CPU 31 distributes the file (that is, by one operation of the X channel button). It is determined whether the distribution of all the image files of the image file to be received has been completed, and when affirmative results are obtained, the CPU 31 stops the interrupt timer 46B for moving picture normal reproduction display in the next step SP71 and resumes normal reproduction. By activating the display interrupt timer 46A, the display processing of the subsequent image data is transferred to the normal playback display interrupt timer 46A (FIG. 32), and then the moving picture normal playback display timer processing procedure RT4 in step SP72. To exit.

On the other hand, if an affirmative result is obtained in the above-described step SP70, this means that the processing of the file has not been completed at all, and at this time, the CPU 31 proceeds to step SP72 and immediately proceeds with the interrupt timer for moving picture normal playback display. After the RT4 is terminated, the processing sequence RT4 is repeated each time the interruption video 46 for moving picture normal reproduction display generates interrupt data.

(5-7) Interrupt timer processing procedure for playback display during video

Subsequently, when the playback display interrupt timer 46C is activated during the moving picture in step SP21 of the X channel button processing procedure RT1 (Fig. 27), the CPU 31 generates interrupt data in the playback display interrupt timer 46C during the moving picture. Each time, the playback timer interrupt timer processing procedure RT5 is executed during the moving picture in FIG.

At this time, the CPU 31 determines whether there is image data in the delivered image memory 35C in step SP82.

If an affirmative result is obtained here, this means that there is moving image data to be reproduced in the middle, and at this time, the CPU 31 proceeds to step SP83 to read the divided image data into the moving image division memory 49 and the next step SP84. Overwrite the divided image data from the middle to the moving image empty file FILEX (FIG. 30 (C)) (in the case of FIG. 30 (D), the division frame 6X to the sixth to tenth empty files of the moving image empty file FILEX). 10X overwrites sixth to tenth divided image data F6 to F10).

Subsequently, the CPU 31 determines whether the moving picture reproduction start has ended in step SP85, and when a negative result is obtained, the reproduction start command file [7, smi] is interrupted in step SP86 (using the one created in step SP20 in Fig. 27). Play along the way.

On the other hand, if an affirmative result is obtained in step SP85, this means that it is not an intermediate playback, and at this time, the CPU 31 proceeds to step SP87 without performing playback during step SP86.

In this way, the CPU 31 terminates the reproduction of the moving image data written in the middle of the moving image empty file FILEX in the middle, and proceeds to step SP87 to check whether the file has ended. By stopping the interrupt timer 46C and starting the normal playback display interrupt timer 46A, the processing of other image data of the file is transferred to the processing of the normal playback display interrupt timer processing procedure RT3 (Fig. 32), In step SP89, the interrupt timer processing procedure RT5 for playback display is terminated during the moving picture.

On the other hand, if a positive result is obtained in step SP82, this means that playback has ended in the middle, and therefore, the CPU 31 proceeds to step SP87, and if a negative result is obtained in step SP87, this results in the operation of the X channel button. This means that the processing of the series of files to be processed is not finished. Therefore, the CPU 31 directly proceeds to step SP89 to terminate the interrupt timer processing procedure RT5 for playback display during the moving picture.

(5-8) operation

In the above configuration, when any channel button (i.e., X channel button) of the channel selection switch unit DP2 is operated while the control panel display DIP1 is displayed on the display screen 38A of the display 38 (Fig. 26). The CPU 31 of the user terminals 6A, 6B,..., At step SP10 of the X-channel button processing sequence RT1, obtains the time table TMDAT of the X-channel corresponding to the X-channel button operation time from the program control server 3. The data is delivered to the channel table data memory 35A (Fig. 23).

Here, the types of images distributed by the time table TMDAT include a normal image "html", a compressed image "cab", and a moving image split image "paz", and the moving image split image "paz" is reproduced from the beginning, and Playback may occur during the process.

The CPU 31 judges the type of the image in step SP11 (Fig. 27), and in the case of midway playback of the moving image, plays back the moving image empty file FILEX (Fig. 30 (C)) (step SP19) and then halfway playback. The start command file [7, smi] is created (step SP20), and a time table is transmitted to the communication interrupt timer 45 and the interrupt display 46C for playback display during the moving picture, and the start time file is started.

On the other hand, in the case of normal reproduction display image data, the CPU 31 transfers the time table to the communication timer 45 and the display interrupt timer 46 at step SP12 (Fig. 27) to start it.

In the case of the normal image &quot; html &quot; and the compressed image &quot; cab &quot;, the communication interrupt timer 45 downloads the image information from the distribution server 2 and stores it in the distribution image data memory 35C (steps SP34 and SP35 in Fig. 31). On the other hand, in the case of the moving picture "paz", the attribute file information "PazInf" is downloaded from the delivery server 2, and the split file in the attribute file information "PazInf" is additionally retained in the delivery image data memory 35C. (Steps SP40 and SP41 in Fig. 31).

In this manner, the CPU 31 displays the image data on the program display unit DP1 of the display 38 by driving the display timer according to the type of image using the image data distributed to the distributed image data memory 35C.

That is, when image data is delivered to the display interrupt timer 46 and started, the CPU 31 first starts the normal image "html" and the compressed image "cab" based on the normal playback display panel processing procedure RT3 (Fig. 32). Is delivered, the normal image "html" is directly decompressed or the compressed image "cab" is decompressed and displayed on the display screen 38A using the first or second browser BR1 or BR2 (Fig. 32). Step SP48, SP49 or SP51, SP52).

On the other hand, when displaying the moving image divided image "paz" from the beginning, the CPU 31 judged that the moving image divided image "paz" after processing in the interrupt timer processing procedure RT3 for normal reproduction display (FIG. 32). (SP45 in FIG. 32), the normal playback display timer 46A is stopped and the video normal playback display timer 46B is started (SP56), so that the interrupt timer processing sequence RT4 for video normal playback display (FIG. 33) is performed. In this case, the moving picture is reproduced (step SP68 in Fig. 33).

This moving picture is reproduced based on the attribute file information [PazInf] (Fig. 29 (D)), and a moving picture empty file FILEX is formed in the moving picture dividing memory 49 from the total capacity of the image data (Fig. 30 (C)). By overwriting the divided image data in this moving image empty file FILEX, each moving image data is delivered to the distributed image data 35C every frame (before all the frame images arrive) and displayed on the sequential display screen 38A. (Steps SP64, SP65, SP66, SP68 in FIG. 33).

On the other hand, in the case of viewing from the middle of the moving image, the CPU 31 starts reproduction during the creation in the steps SP19 and SP20 of the X-channel button processing sequence RT1 (FIG. 27) in the interrupt timer for processing display RT5 (FIG. 34). Playback can be displayed by the command files [7, smi] (steps SP83, SP84, SP86 in Fig. 34).

In this way, when the processing of the moving picture normal playback display interrupt timer processing procedure RT4 (FIG. 3) and the moving picture display playback interrupt timer processing procedure RT5 (FIG. 34) is finished, the CPU 31 once interrupts the normal playback display interrupt timer. By taking over the processing to the processing sequence RT3 (FIG. 32) (step SP71 in FIG. 33, step SP88 in FIG. 34), even if other image data is subsequently distributed to the corresponding moving image data, the interrupt timer processing sequence RT3 for normal playback display Through Fig. 32, display processing of all images (html, cab, paz) can be reliably continued.

As described above, according to the fifth embodiment, image data representing various images is distributed from the program distribution server 4 simultaneously to a plurality of user terminals 6A, 6B, ... connected to the information transmission network at the same display time. The information delivery system can be realized.
