a and 16a are provided.

Customer management system 121 and broadcasting device 1
Reference numeral 22 denotes a digital television receiver which is installed in the broadcasting station 12 for performing satellite digital multi-channel broadcasting using the communication satellite 15, and which has viewing functions 13 and 14 having an Internet connection function. Therefore, through the communication path 17, a television program broadcast by audio and image information,
A data broadcast to which a computer program or the like is transmitted is distributed. As a program service of the data broadcast, a relatively small-capacity program such as multimedia information or a search program is transmitted to a broadcasting station 12 using a ring buffer or the like.
Is repeatedly transmitted within a predetermined time. In addition, the customer management system 121 manages customer information for receiving broadcast services. It should be noted that there are actually a plurality of viewing devices as viewers to receive this broadcast, in addition to the viewing devices 13 and 14, but these are omitted in FIG. Hereinafter, search of multimedia information in the viewing device 13 will be described.

The multimedia information search program executed by the viewing device 13 is supplied to the viewing device 13 via the communication satellite 15 using the data broadcast transmitted from the broadcasting device 122. The search program is, for example, BML
(Broadcast Markup Language) and HTML (Hypertext
Although described in a language such as Markup Language), the following two types of forms of the search program received by the viewing device 13 can be considered.

The first mode is a case where the program to be received is composed of not only the search program itself but also a plurality of files including multimedia information to be searched, for example, a case where the program includes a database file of multimedia information. is there. In this case, the files are all linked in the search program, and the multimedia information is searched using only these files. Use of such a search program is suitable when the multimedia information to be searched has a small capacity.

In the second embodiment, the viewing device 13 receives only a search program described in BML or HTML, and stores the search program in another database such as the information providing device 16 through a network such as the Internet. This is a case in which the communication is performed with the multimedia information being obtained and the information is obtained as a search result. In this case, the search program is executed together with the display by the browser.

The search program is received by the viewing device 13 in one of the two types described above, and is used for searching for multimedia information. At this time, the viewer, for example, displays the information in a dialog on the display screen of the viewing device 13. The display screen is transited by an event input such as input or selection of a selection button, and this operation is repeated until the target multimedia information is reached. However, during this search process,
It is conceivable that a plurality of paths exist before reaching the same multimedia information due to a difference in input information of the viewer and the like.

Here, as an example, FIG. 3 shows a homepage screen by a used car search program, and a search route will be described. Homepage screens 31, 32, 33 of FIG.
And 34 are displayed by a browser on a display screen provided in the viewing device 13, but the image frame of the browser is omitted in FIG.

The viewer first selects the selection buttons 31a and 31b on the homepage screen 31 and selects Tokyo,
After limiting the sales area such as Kanagawa, select button 31
From c and 31d, select whether to search for the target used car from the model or from the manufacturer. At this time, either of the selection buttons 31c and 31d can be selected depending on the viewer's will, even if the target used car is the same.

Select button 31c on homepage screen 31
Is selected, the home page screen 32 is displayed next, and if the selection button 31d is selected, the home page screen 33 is displayed next. That is, the homepage screen 32 has selection buttons 32a, 33b, 33c, 33
d and 33e are used to select a vehicle type such as a minicar, a two-door car, a three-door car, a four-door car, a wagon car, etc. The homepage screen 33 has selection buttons 33a, 33
"HOND" and "TOYO" by b, 33c and 33d
This is a screen for selecting a car manufacturer name such as "NISS" or "MAZ". The next home page screen which is read by selecting the selection button in this manner is read from the file included in the search program as described above, or the other information providing apparatus 16 through the communication path 18.
Read from

After that, the screen changes by further selecting each of the selection buttons, and finally the homepage screen 3
At 4, the target used car information is displayed, and this screen is the only final search result. The number of screens that have transited to the homepage screen 34 may be different for both routes. As described above, in the information search by the search program, there is a case where the user arrives at only one target screen although there are a plurality of transition paths in the search process. It should be noted that a transition screen in progress from the homepage screens 32 and 33 to the homepage screen 34 is omitted in FIG.

In the viewing device 13 shown in FIG. 2, the transition path leading to such a final search result is identified and stored in the storage device 13c, and transmitted to the customer management system 121 via the communication path 18 by the transmission / reception device 13a. . In the customer management system 121, information on the transition route is received by the transmission / reception device 121a from the plurality of viewers such as the viewing devices 13 and 14 using the search program by the data broadcasting service via the communication path 18, and the information database 121b And the information control device 121c performs statistical processing on the transition path information for each type of search program. Based on this statistic, the broadcasting station 12 providing the service can know what transition path the viewer has searched for multimedia information when using the search program, and the transitions used by the most viewers Since the route is highly comfortable for the viewer in the search operation and the route is likely to be the shortest, it is considered that the route should be adopted when executing the relevant search program. Change the content.

For example, if it is found from the above statistical results that a small number of viewers have searched through the transition path from the homepage screen 31 to the homepage screen 32 and the homepage screen 33 in the search screen of FIG. Does not require a transition path from the homepage screen 31 to the homepage screen 32, it is considered that the file forming the homepage screen 32 may be omitted. If the search program is optimized in this way, the viewer can select the transition path from the homepage screen 31 to the homepage screen 33 and the homepage screen 34 without hesitation, and the possibility of arriving at the search final result more quickly increases. Thus, a more comfortable search operation can be performed without shifting to an unnecessary screen display.

The search program optimized as described above is transmitted from the customer management system 121 to the viewing device 13 via the communication device 17 via the broadcasting device 122, and the search program stored in the viewing device 13 is updated. used.

The optimization of the search program not only provides the service providing the viewer with a better service, but also reduces the size of the program by deleting extra files in the program. It is possible to suppress the transmission cost of a search program to be distributed in the future. In addition, the reduction in the capacity of the program can reduce the overhead in information processing when the program is executed by the viewing device 13, and is efficient in executing the program.

Note that the supply of the search program from the broadcasting station 2 as a business operator to the viewing devices 13 and 14 is not limited to transmission via the communication path 17 using communication satellite data broadcasting.
For example, a data broadcasting service in a broadcasting satellite digital broadcast or a terrestrial digital broadcasting using a broadcasting satellite instead of the communication satellite 15 is used, and the transmitting / receiving device 121a of the customer management system 121 and the transmitting / receiving device 12 of the broadcasting device 122 are used.
2a, the data is transmitted through the Internet of the communication path 18 or a CD-ROM (Compact Disk-Read Online)
y Memory) or the like, and may be conveyed to the viewer in a state recorded on a conveyable information storage medium. The same applies to the transmission of the search program optimized in the customer management system 121 to the viewing devices 13 and 14. further,
The transmission of the transition path information from the viewing devices 13 and 14 to the customer management system 121 is performed by the communication path 18 via the Internet.
In addition to the use of the information, a portable information storage medium may be recorded and transported.

The broadcasting station 12 is a cable television station, the viewing devices 13 and 14 are connected to a cable television network, and a search program and transition path information are transmitted and received using a bidirectional data communication service or the like. You may.

Reference numerals 4, 405, 406, and 407 indicate links to the program files of the screens to be displayed next, and these links are performed only when necessary.

For example, when the home page screen 31 at the head of the used car search of the file 41 is displayed and the selection button 31d of "Search by manufacturer" is clicked, the home page of the file 43 in which the selection buttons of the manufacturer name are arranged The screen 33 is displayed. At this time, the identifier (pointer) of the program function for calling the file 43 included in the file 41 is designated, and the DLL
Is linked to the file 43, and the file 43 is opened. Similarly, on the homepage screen 33, "HON
When the "D" selection button 33a is clicked, an identifier for calling the file 44 is designated, the file 44 is opened, and a home page screen 34 showing search results is displayed.

In the above example, the files 41, 42, 43 and 44 are all stored in the storage device 13c of the viewing device 13, and the multimedia information to be searched is all linked in the search program. The target multimedia information is transmitted to the information providing device 16 through the network.
