Description

The present invention relates to an information integrated display method, an information integrated display system, and a server device applied to a document browsing system using a network.

  Conventionally, for example, a CD-ROM, which is a read-only memory using a so-called compact disk (hereinafter referred to as a CD), a CD-I (CD-Interactive), and the like are used for information such as documents and images. Is used as an information recording medium. The CD-ROM or CD-I uses a so-called compact disc on which audio signals are recorded, that is, the same optical disc as a CD-DA (Compact Disc-Digital Audio), and is used for documents, sounds, and moving images. , Still images are recorded as data files.

  In recent years, so-called video CDs for recording moving image signals compressed and encoded on the same optical disk as the CD have also appeared. This video CD standard is a so-called karaoke CD (CD video karaoke CD) for the purpose of simple video playback, as shown in FIG. 7, among the various standards defined as CD standards. ) An extension of the standard. The karaoke CD is an optical disc whose main purpose is to be used in karaoke or the like that is used by mixing an audio signal input from a microphone and a music signal.

  The above-mentioned video CD is applied with a standard in which functions such as still image reproduction and simple menu reproduction are added to the digital video reproduction function using MPEG1 (Moving Picture Experts Group Phase 1), which is an international standard for data compression. . That is, for example, as shown in Table 1, by adding functions such as playback control for realizing high-definition still images of 704 × 480 pixels and menu playback, for example, not only simple video playback It can be used in a wide range of applications, such as music software, educational software, and electronic publishing software that combine video and still images.

  The video CD standard is also compatible with the existing CD-I FMV (Full Motion Video) standard. In other words, the video CD is a bridge standard that can be played back by a player corresponding to the CD-IFMV standard, thereby maintaining consistency in the standard and compatibility of the optical disc.

  Furthermore, unlike the CD-I, the video CD standard does not specify an operating system (OS), so it can be used not only for dedicated players but also for personal computers and game machines equipped with the above-mentioned MPEG video board. It is possible.

  Further, the disc configuration of the video CD conforms to the form 1 of the CD-ROM XA specification, and file management conforms to ISO 9660 standard of the International Organization for Standardization (ISO).

  Here, as shown in FIG. 8, the recording area of the video CD is roughly composed of a lead-in area, a data area (tracks 1 to 99), and a lead-out area.

  The track 1 is a video CD data track, and a video CD data information section (INF VCD) is newly provided for the CD-ROM XA standard. In this video CD data / information section, disc information, list / ID / offset / table (LOT), playback control (PBC), etc. are recorded as various disc information. The list / ID / offset table (LOT) stores IDs (identification information) of moving images and still images recorded on the disc. The playback procedure (PBC) records the playback procedure described in the list format. Data such as still images used for the menu screen can be written in the segment play section.

  The track 1 is also provided with a CD-I application software section. When a video CD standard disc is reproduced by a CD-I FMV player, the player first reads this area and reproduces it according to the procedure of the application. Further, when playing back on a device such as a personal computer that requires directory management, files are managed according to the directory structure as shown in FIG. That is, in FIG. 9, a video CD directory shown as VCD in the figure is added to the conventional directory structure consisting of CD-I, MPEG audio, video, and karaoke. For example, in the VCD directory shown in FIG. VCD stores video CD information. In the figure, ENTRIES. The VCD stores the start position of MPEG standard moving picture and MPEG standard audio data. The VCD stores a list, ID, offset, and table, and PBC. The VCD stores playback control information.

  Ordinary MPEG data is recorded on track 2 and subsequent tracks, and can handle up to a maximum of 99 tracks. However, in the video CD standard, not only simple interactive software using playback control, but also a disc that reproduces a high-definition still image using only track 1 can be realized.

  Next, the recording format of the video signal and audio signal of the video CD complies with MPEG1. Usually, about 1.2 Mbit / sec is assigned to the video signal and about 0.2 Mbit / sec is assigned to the audio signal. As shown in FIG. 10, the screen size for the image is NTSC signal (frame frequency is 30 Hz) and P or movie film (frame frequency is 24 Hz), 352 × 240 pixels, PAL signal (frame frequency is 25 Hz). In this case, it is 352 × 288 pixels. The format for the audio signal uses layer 1 of MPEG1. The MPEG audio signal supports a wide range of encoding speeds from 32 kbit / sec to 448 kbit / sec, but the video CD is limited to 224 kbit / sec in consideration of easy software production and high sound quality. is doing. Note that the playback mode is a stereo channel (2 channels), and can be used for so-called karaoke software such as recording music on channel 0 and music and singing voice on channel 1.

  Next, the track structure of the video CD is shown in FIG. In other words, MPEG video and audio data are interleaved on the disc, and video data and audio data are arranged at a ratio of 6 to 1 on average. In addition, as in a conventional CD player, assuming that the search is performed by track number, 150 sectors are provided as a pause margin, and 15 sectors are provided as a front margin and a rear margin. This is to reduce the influence on the bit stream when searching.

  Further, as shown in FIG. 12, the sector format of MPEG video data is composed of a pack composed of a pack header and pack data. One pack is composed of 2324 bytes, which is the user data area of one sector of the CD-ROM. However, 12 bytes are allocated as a pack header, 13 bytes are allocated as a packet header, and 2279 bytes are allocated as a data portion. An extra 20 bytes (recording zero) is added to this to make 2324 bytes, which is the same as a video, as one pack. In FIG. 12, PTS is a display time part (presentation time stamp), DTS is a decoding time part, SCR is a system clock reference in the figure, STD indicates a system target decoder.

  The sector format of MPEG audio data is basically the same as that of video data. However, 12 bytes are assigned as a back header, 13 bytes are assigned as a packet header, 2279 bytes are assigned as a data part, 2304 bytes are assigned as 1 back, and an extra 20 bytes (recording zero) is added to the video data. The same 2324 bytes are used as one back.

  As a conventional technique, Patent Literature 1 discloses a catalog shopping system that uses an electronic publication medium such as a CD-ROM as a catalog.

Japanese Patent Laid-Open No. 5-398337

  If an optical disc such as a CD-ROM or a video CD as described above is used as an information recording medium, document information such as characters and images can be provided to the user. In particular, in the case of a video CD, moving image information can be provided to a user easily and inexpensively. However, when information is recorded on these optical discs and provided to the user, the recorded information becomes outdated as time elapses from the time when the optical disc is provided to the user (that is, when the information is issued). There is a problem that the value is reduced.

  On the other hand, on the Internet, which is a two-way information system that has been booming with the recent introduction of the so-called WWW (World Wide Web) system, for example, software called a browser is used for users. The side can acquire the latest various information from the information provider side in an interactive format. Note that the WWW is an information providing system that enables browsing of information such as text, images, and sounds that can be used on the so-called Internet as a network in a hypertext format. The WWW browser is software required to use the WWW for displaying data on demand or displaying data from the network. That is, the WWW browser reads a document described in a language for describing a document in a hypertext format called HTML (Hyper Text Markup Language), for example, from a server or a terminal operating the browser, and edits it. And display. In this way, in a system using a WWW browser, a transmission request is made from a terminal to each server that is scattered in a plurality of locations and each has information, and is transmitted from each of these servers on the terminal side. Information can be displayed in combination. Furthermore, the Internet is a computer network network in which computer networks existing in companies, universities, etc. are connected to each other through a wide area line, and is spread all over the world. Various services using the Internet have already been actively performed for e-mail services, file transfer services, information retrieval services, and the like. In addition, hypertext is a mechanism that facilitates retrieval of information by associating text, diagrams, and the like, that is, by attaching links.

However, in the system that provides information to the user side via the network as described above, it is possible to collect and edit and display information scattered in a plurality of places on the user terminal side. At this time, the user terminal can only edit and display the information supplied from the server. For example, the information on the terminal can be embedded and edited in a document obtained from the server, There is a problem that a link for reference cannot be created. Further, when all the data constituting a document or the like is acquired from the network, for example, if the document includes image (especially moving image) information, it takes time to acquire the information, and the load on the network There is also a problem that increases.
Therefore, the present invention has been made in view of the above, and can always provide the latest information, and even if information to be acquired includes information on an image (particularly a moving image), acquisition of the information is possible. Information display method and information that can be edited and displayed by organically combining the information held by the user's terminal itself and the information held by the server without requiring a long period of time and a low network load. An object is to provide an integrated display system and a server device .

Information integration display method of the present invention, the non-updated information and the optical disk for holding, the specific information for specifying the non-updated information that the holding, a page description language, non-content update information, non-updated information creation date , A client terminal having at least a specifying information generating unit that generates based on one of the disk IDs, a transmitting / receiving unit that transmits and receives information, and a display unit that displays information, and an update that holds update information that is updated as needed Information integration in a system comprising: an information holding unit; a transmission / reception unit for transmitting / receiving information; and a server having at least update information generation unit for generating related update information based on the identification information transmitted from the client terminal In the display method, the client terminal side uses the same language decoding display means as the server side, and the server terminal By the non-updated information held by the acquired update information and the client terminal to display the same display area of the display means, to solve the problems described above.

In the information integrated display system of the present invention, the non-updated information and the optical disk for holding, the specific information for specifying the non-updated information that the holding, a page description language, the non-updated information content, the non-updated information A client terminal having at least a specifying information generating means for generating based on either the creation date or the disk ID, a transmitting / receiving means for transmitting / receiving information, and a display means for displaying information, and update information updated as needed An update information holding means, a transmission / reception means for transmitting / receiving information, and a server having at least update information generation means for generating related update information based on the specifying information transmitted from the client terminal, On the client terminal side, the update information acquired from the server and the class are displayed using the same language decoding display means as the server side. By displaying the non-updated information held by Ant terminal on the same display area of the display means, to solve the problems described above.
Furthermore, the server device of the present invention, the non-updated information and the optical disk for holding, the specific information for specifying the non-updated information that the holding, a page description language, non-content update information, non-updated information creation date A server device connected to a client terminal having at least a specifying information generating means for generating based on one of the disk IDs, a transmitting / receiving means for transmitting / receiving information, and a display means for displaying information, which are updated as needed Update information holding means for holding update information to be transmitted, transmission / reception means for transmitting / receiving information, and update information generation means for generating related update information based on the identification information transmitted from the client terminal This solves the above-mentioned problem.

  That is, according to the present invention, when accessing the server, information on the client side is automatically transmitted together, and whether the server uses information on the client side based on the information (such as embedding information). By sending the optimal information suitable for the client side environment, such as judgment and embedding of link information, the network load can be reduced by utilizing the information owned by the client side, and remote and local awareness when browsing documents It is possible to alleviate the need to provide a seamless usage environment.

  In the present invention, update information acquired from a server via a wide area network and updated information that is updated as needed and non-update information that is individually held on the client side are displayed in a unified manner, and the display contents are configured. By describing the location of each information in a common page description language and displaying the update information acquired from the server using the common language decoding display means and the non-update information held on the client side in the same display area The latest information can always be provided, and even if image information (especially moving images) is included in the information to be acquired, it does not take a long time to acquire the information, and the load on the network is small. It is possible to edit and display the information that the personal terminal itself has and the information that the server has in an organic manner.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of an information integrated display system to which the information integrated display method and apparatus of the present invention is applied.

  The information integrated display system shown in FIG. 1 is updated individually from the server 100 via a wide area network such as the Internet 130 and updated on an as-needed basis on the user terminal (hereinafter referred to as client terminal 120) side. In order to display the stored non-update information on the display device 124 of the client terminal 120 in a unified manner, the location of each piece of information constituting the display content is described in a common page description language, and the common language decoding The update information acquired from the server 100 using the display means and the non-update information held on the client terminal 120 side are displayed in the same display area of the display device 124. The update information and the non-update information are both composed of information such as characters and images. In the following description, characters and images handled by the server 100 and the client terminal 120, other file data, ID information, and the like are combined into a document. I will call it.

  That is, in the information integrated display system of the configuration example of the present invention, a document of update information such as characters and images from the document search / transmission server 100 and a client terminal which is a browsing terminal connected to the server 100 In combination with 120 documents of non-update information such as characters and images, as shown in FIG. 2, it can be displayed in the same display area 140 on the display screen of the display device 124. More specifically, in the system of the configuration example of the present invention, for example, the document of the non-update information which is information such as an image (especially a moving image) having a large data amount and a relatively long update period, an image that is not updated, characters and the like. Information is acquired from the optical disk 126 such as a CD-ROM or a video CD inserted in the storage device 125 of the client terminal 120, and document information of update information such as text information with a short update period is acquired from the server 100 (network Display information consisting of characters and images by combining these pieces of information and displaying them. In the example of FIG. 2, for example, an MPEG moving image (for example, promotion video) acquired from the optical disk 126 is displayed in the display area 141 in the same display area 140 of the display device 124, and a server is displayed in the display area 142. Information acquired from 100 (for example, movie commentary, screening hall, screening time, latest information, etc.) is displayed.

  In FIG. 1, the communication unit 111 of the server 100 is, for example, an HTTP (Hyper Text Transfer Protocol, a native protocol used in WWW for exchanging hypertext over the Internet) server, and the page description unit 112 is a so-called page description unit 112. A CGI (Common Gateway Interface) program can be used. The update information that is updated as needed includes, for example, characters and image information written in a page description language called HTML (HyperText Markup Language).

  On the other hand, the function expansion unit 122 of the client terminal 120 includes a plug-in program, and the moving image reproduction unit 123 includes an MPEG1 decoder (which may be either hardware or software) and its control software. The optical disk 126 inserted into the client terminal 120 is a CD-ROM, a video CD, a hybrid video CD described later, or the like, and is reproduced by a storage device (for example, a disk drive device) 125. . For this reason, the non-update information obtained by reproducing from the optical disk 126 is characters, image information, program data, or the like when the optical disk 126 is a CD-ROM, and when it is a normal video CD. The moving image information is decoded by the MPEG1 decoder. The case where the optical disk 126 is a hybrid video CD will be described later. Further, the non-update information is reproduced from the optical disk 126, and when the client terminal 120 has an HDD (Hard Disk Drive) or FDD (Floppy Disk Drive), Information reproduced from a floppy disk or information supplied from another terminal connected via the LAN when the client terminal 120 is connected via, for example, a LAN (Local Area Network) (for example, another terminal) Information obtained from a disk drive or HDD). Further, the non-update information may be expressed in the HTML page description language.

  Further, the browser 121 as the common language decoding display means in the server 100 and the client terminal 120 is, for example, browsing software called a WWW browser such as Netscape Navigator (trademark) of Netscape Communication. For example, the display area 140 is secured on the display screen of the display device 124 based on the designation of the file name to be displayed, the file format to be displayed, and the area to be displayed described in the HTML. The non-update information etc. can be displayed. At this time, the browser 121 also activates a necessary function from the preset plug-ins of the function expansion unit 122 based on the file format to be displayed described in HTML. As the same display area on the display device 124 of the client terminal 120 when the browser 121 is used, for example, the window of the Netscape Navigator can be cited as an example.

  As described above, in the information integrated display system configuration of this configuration example, a document is expressed in a page description language such as HTML, for example, but a description of embedding a moving image in the document is expressed by the HTML. For example, the following notation can be used.

<EMBED SRC = "file: //vcd/mpegav/movie01.det" WIDTH = 320 HIGHT = 240>
The portion enclosed by double quotation marks (") following the SRC represents the file name of the moving image to be displayed, and the size of the area secured for embedding the moving image in the document is represented by WIDTH and HIGH. That is, in this example, the width direction (horizontal direction) is 320 pixels, and the vertical direction (vertical direction) is an area for 240 pixels.
Therefore, when the browser 121 of the client terminal 120 in the system of FIG. 1 detects the above description in the HTML file (determined by the EMBED tag), the browser area on the document is set on the document based on the WIDTH and HIGH. Secure and do document layout. Further, the URL (file name of embedding data) indicated by the SRC is passed to the plug-in of the function expansion unit 122. The URL is an abbreviation for Uniform Rosource Locator, and is a description for designating a partner and a protocol to be used when accessing an information source via the Internet. For example, the URL described as http://WWW.AAA/BBB/CCC.html is WWW. This means that a file named CCC stored under a directory named BBB of a server named AAA (host) is copied (or downloaded) based on the http protocol.

  Based on the received file name, the plug-in of the function expansion unit 122 instructs the moving image reproduction unit 123 to display a moving image in an area secured by the browser 121. Further, information such as mouse operation performed in the reserved area is passed to the plug-in of the function expansion unit 122, and the plug-in performs playback, stop, etc. on the video playback unit 123 based on the operation. Give instructions.

  Based on the file name given from the plug-in of the function expansion unit 122, the video playback unit 123 opens the moving image file from the storage device 125, and on the display screen of the display device 124 based on the plug-in instruction Display a moving image at the location.

  A more detailed operation of the above-described information integrated display system will be described with reference to the flowcharts of FIGS. FIG. 3 shows the operation on the client terminal 120 side, and FIG. 4 shows the operation on the server 100 side.

  First, as a process of opening a local document in step ST1 in FIG. 3, for example, the optical disk 126 is inserted into the storage device (disk drive) 125. Alternatively, the process of reading predetermined information from the predetermined area of the inserted optical disk 126 and storing it in the document data storage unit 127 can be included in the process of opening the hand document. Here, for example, when a page description language file such as HTML is recorded as the predetermined information in the predetermined area of the optical disc 126, the page description language is analyzed in step ST2.

  Next, as a result of analyzing the page description language, when displaying the non-update information document recorded on the optical disc 126 on the display device 124, an external document is displayed together with the non-update information. When the instruction is obtained, it is determined yes in the external document acquisition determination process in step ST3. Alternatively, when the page description language as described above is not recorded on the optical disc 126, when the non-update information document recorded on the optical disc 126 is displayed on the display device 124, the non-update information and an external Even when there is an instruction to display the document at the same time, it is determined as YES in the external document acquisition determination process in step ST3. When it is determined NO in step ST3, the process proceeds to step ST7 described later.

  When it is determined as YES in step ST3, document information is transmitted from the client terminal 120 to the server 100 as shown in step ST4. Here, when the page description language is analyzed in step ST2, the obtained page information is transmitted to the server 100 as document information. If the page description language is not recorded on the optical disk 126, for example, information on the client terminal 120 in the browser 121 (for example, information content, creation date, drive name, and inserted disk) ID etc.) and ID information indicating the location are transmitted to the server 100 as document information.

  At this time, the communication unit 111 side of the server 100 is waiting for a request from the client terminal 120 as in step ST20 of FIG.

  When receiving the transmission from the client terminal 120 in step ST20 of FIG. 4, the server 100 performs the processing from step ST22 to step ST24 until receiving a transmission end notification in step ST21. In step ST22, for example, the communication unit 111 analyzes the document information received from the client terminal 120, and stores the received document information in the document data storage unit 113 if necessary. Here, for example, when the document information from the client terminal 120 is the information of the page, the communication unit 111 analyzes the page, and in step ST23, the document information corresponding to the description of the page is stored in the document data storage unit. In step ST24, a page is created from the communication unit 111 and transmitted to the client terminal 120 side together with the document information from the document data storage unit 113. When the document information received from the client terminal 120 is the ID information or the like, the communication unit 11 analyzes the ID information or the like, and the document information corresponding to the analysis result of the ID information or the like is Acquired from the document data storage unit 113 and transmitted to the client terminal 120 from the communication unit 111 together with the page created in the page description unit 112.

  The processing from step ST20 to step ST24 in the server 100 is repeated until a transmission end notification is received from the client terminal 120 in step ST21. In addition, when a transmission end notification is received from the client terminal 120 in step ST21 and it is instructed that the information stored in the document data storage unit 113 may be discarded, the stored information is discarded in step ST25. Then, the process returns to the transmission request waiting state in step ST20.

  Returning to FIG. 3, the browser 121 of the client terminal 120 determines whether or not the document information is received from the server 100 in step ST5. At this time, if not received yet, the determination in step ST5 is repeated. If received, all the document information is received from the server 100 in step ST6, and the received document information is temporarily stored in, for example, document data. Stored in the unit 127.

  In step ST7, the browser 121 analyzes page information out of the document information received from the server 100 and stored in the document data storage unit 127, and performs layout according to the description of the page. A character or image document from 100 and a character or image document from the optical disk 126 or the like are combined and displayed on the display device 124. Further, if the plug-in needs to be activated, the function expansion unit 122 activates the plug-in. Here, when the plug-in is activated, the moving image reproducing unit 123 is activated by the activated plug-in, and the moving image reproducing unit 123 converts the moving image data reproduced from the storage device 125 into the description of the page. It is displayed at a predetermined position.

  Next, the browser 121 enters a state of waiting for the user's operation, and executes it when the user performs an operation. As a state waiting for the user's operation, in step ST8, it is determined whether or not the above-described document transmission / reception and display processing is to be ended. If it is determined not to be ended, the process proceeds to step ST9. In step ST9, it is determined whether or not to open a different document, for example, whether or not a page has been switched, while waiting for the user operation. When it is determined in step ST9 that a different document is not to be opened, the process returns to step ST8, and when it is determined that the document is to be opened, the server 100 is notified in step ST10. At this time, the information notified to the server 100 varies depending on the user's operation, and is various such as the ID of the title stored in the optical disc 126 and the name of the user (user).

  Thereafter, the document is opened in step ST11, and the process returns to step ST2 and subsequent steps.

  Next, the above-described hybrid video CD that can be used in the configuration example of the present invention will be described.

  As described above, the storage device 125 of the client terminal 120 is a disk drive device capable of reproducing the optical disk 126 such as a CD-ROM or a normal video CD. Here, the video CD standard conforms to the CD-ROM XA standard, and therefore, the video CD can be read by a personal computer or the like in the same manner as a normal CD-ROM. For this reason, in the configuration example system of the present invention, data and application software used in a personal computer such as a CD-ROM are recorded in addition to the moving image and audio data used in the conventional video CD described above. A video CD is also used. As described above, the video CD used in the configuration example of the present invention has the functions of a conventional video CD and a CD-ROM, and therefore will be referred to as a hybrid video CD in the following description. The hybrid video CD used in the configuration example of the present invention is the same as a conventional video CD or CD-ROM because data and application software used in a personal computer and the like are recorded together with video and audio data. Titles that were put out as separate packages while using the material can now be handled with a single disc, and if this hybrid video CD is used, the software control side in the disc playback device (disc drive) The load of will also be reduced. Furthermore, since the hybrid video CD can be used on a personal computer or the like, functions that could not be realized with a conventional video CD can be added, and the applications can be expanded.

  The format of the hybrid video CD used in the configuration example of the present invention will be described below.

  The recording format of the hybrid video CD includes a moving image data area in which moving image data that can be reproduced as a conventional video CD is recorded, and data and application software used in a personal computer such as a CD-ROM. And an application area in which is recorded. Here, in the application area of the hybrid video CD, for example, the plug-in of the above-mentioned Netscape Navigator and HTML data to be displayed in the Netscape Navigator are recorded.

  The recording format of the hybrid video CD will be described more specifically with reference to FIG. The recording format of this hybrid video CD is roughly divided into a lead-in area, a data area (tracks 1 to N), and a lead-out area. In the example of FIG. 5, moving image data is recorded in tracks 2 to M, and CD-DA data is recorded in tracks M + 1 to N.

  The track 1 is a video CD data track. Like the conventional video CD whose recording format is shown in FIG. 8 described above, the video CD data information unit (INF VCD) corresponds to the CD-ROM XA standard. Is provided.

  Here, in the video CD information area (INF / VCO) in the hybrid video CD shown in FIG. 5, as various disk information, disk information, entry table, list ID offset table (LOT), play・ Sequence descriptors, etc. are recorded. The disc information is information for recognizing a video CD, the entry table is a table indicating entry points, the list ID offset table indicates the address of a reproduction list, and a play sequence descriptor. Consists of a playlist and control data. The primary volume descriptor part (PVD) of track 1, the karaoke basic information area, the segment play item area, and the like are the same as in the conventional standard.

  On the other hand, in the CD-I application area of track 1 of the hybrid video CD, the following are recorded as application programs in the hybrid video CD standard.

  For example, as a program for enabling playback of a video CD under the operating environment of an operating system (OS) for a personal computer, the image and audio data compressed and recorded by MPEG1 stored in the video CD are decoded. A video CD playback program necessary for configuring the above-described moving picture playback unit 123 when a hardware-structured MPEG1 decoding board is not provided, and a program to be described later. A file for automatic activation (“AUTOTOR.INF”), a plug-in to be installed in the function expansion unit 122, and the like are stored. If this program runs on, for example, Windows 95 (Windows 95 (trademark)), which is an operating system of Microsoft Corporation in the United States, for example, it is stored under a directory “WIN”. The directory structure and directory names under this directory are free. For data that coexists with other platforms, a data directory is provided and stored in the directory. The directory structure and directory names under this data directory are free. Of course, the OS to be operated is not limited to the Windows 95, but may be another. It is also possible to support a plurality of OSs. In that case, it is necessary to give each directory name so that the directory name does not batting. Programs and the like depending on the OS are stored under the corresponding directories.

  Next, a file (“AUTORUN.INF”) recorded in the CD-I application area of track 1 for realizing the program automatic start function will be described. This program auto-start function is a function that automatically recognizes the type when a hybrid video CD, CD-ROM, conventional video CD, etc. is inserted into a personal computer, and automatically starts the necessary program. is there. This eliminates the need for the user to start the program by double-clicking the icon, for example. In order to realize the program automatic start function, for example, a file for automatic start of the program (hereinafter, the file name of this file is referred to as “AUTORUN.INF”, for example) is stored in the root directory. This “AUTOTOR.INF” is, for example, a text file (ISO 646 characters), in which a program name to be started when a disc such as a CD is inserted is described. The inside of “AUTOTOR.INF” is divided into a plurality of vendor group sections. The vendor group is a line in which the vendor name is enclosed in “[” and “]”, followed by zero or more vendor-specific lines. It consists of. The vendor-specific line includes, for example, a program file name (hereinafter referred to as “open”) to be automatically started, and an icon file name (hereinafter referred to as this file name) when displaying a disk such as a CD as an icon. The file name of the file is defined as “icon”, for example. More specifically, the open file includes, for example, a work for checking whether the Netscape Navigator is present, a work for checking whether or not a plug-in is installed, a work for installing a plug-in if not installed, and a user environment. Stores a program for checking and starting Netscape Navigator and transferring user environment information to the server. For example, if it is not desired to automatically start the program when the disc is inserted, “= open” is not described in the “AUTOTOR.INF” file, but only “icon =” is described. The disk is displayed with an icon designated by “icon =”. Even when the automatic start function is unnecessary, it is desirable to place “AUTORUN.INF” in the root directory in order to prevent the disc from being recognized as a simple video CD. In addition, as an example for realizing the program automatic function function, for example, it is conceivable to use the AutoPlay function supported by the above-mentioned Microsoft Windows 95. In this Windows 95 environment, “autorun” is determined as the vendor name.

  Next, the operation of the information integrated display system of FIG. 1 when the above-described hybrid video CD is used will be described with reference to the flowchart of FIG.

  In FIG. 6, in step ST30, for example, the optical disk 126 is inserted into the storage device 125, that is, a hybrid video CD is inserted. In the next step ST31, the “AUTORUN.INF” file for automatic program startup is read from the CD-I application area of the inserted hybrid video CD, and the program is executed. That is, in the program automatic start file, as described above, for example, work for checking the presence of the Netscape Navigator, work for checking whether the plug-in is installed, work for installing if not installed, Checking the user environment (drive name, inserted disk ID, etc.), starting Netscape Navigator (starting based on URL (server name, program name, etc.) information to be accessed) A program for performing work to be transmitted to the server is stored, and these work are executed. Here, for example, in step ST32, information on the user environment of the client terminal 120 (for example, drive name, inserted disk ID, etc.) is checked, and in the next step ST33, the browser 121 is based on the information on the user environment. In step ST34, the server 100 is accessed.

  Next, when the communication unit 111 of the server 100 receives information from the client terminal 120 in step ST35, the communication unit 111 starts the program of the page description unit 112 in step ST36 based on the received information. In step ST37, a page corresponding to the hybrid video CD inserted in the client terminal 120 is created. In step ST38, information on the created page is transmitted to the client terminal 120.

  When the client terminal 120 receives page information from the server 100 in step ST39, the client terminal 120 analyzes the received page in step ST40. In step ST41, layout is performed in accordance with the description of the analyzed page. Here, if the plug-in needs to be activated, the function expansion unit 122 activates the plug-in as in step ST42. When the plug-in is activated, the moving image reproducing unit (moving image reproducing apparatus) 123 is activated with the activated plug-in as in step ST43. In step ST44, the moving image data reproduced by the moving image reproducing unit 123 is displayed at a predetermined position according to the description on the page.

  As shown in step ST45, the browser 121 displays a page after the plug-in is activated, and then waits for a user operation in step ST46. At this time, if the user performs any operation, the execution is performed in step ST47. For example, when a page switching operation is performed while waiting for the user's operation, the processing from step ST34 onward is repeated, but the information sent to the server 100 at that time varies depending on the user's operation, and is stored in the hybrid video CD. There are various things such as the ID of the title and the name of the user (user).

  As described above, in the information integrated display system of the configuration example of the present invention, information such as an image having a large data amount and a relatively long update period (or not updated) and text information with a short update period supplied by an optical disc, for example. Etc. from the server and combining the information to create a document, the information owned by the user can be utilized, the network load can be reduced, and remote and local when viewing the document The need for awareness is reduced, and a seamless usage environment can be provided, improving operability.

  According to the embodiment of the present invention as described above, the update information acquired from the server via the wide area network and the non-update information individually held on the client side are displayed in a unified manner. The location of each information constituting the display content is described in a common page description language, and the update information obtained from the server using the common language decoding display means and the non-update information held on the client side By displaying in the same display area, the latest information can always be provided, and even if the information to be acquired includes image (particularly moving image) information, it does not take a long time to acquire the information. Further, the load on the network is small, and editing and display in which information held by the user terminal itself and information held by the server are organically combined is possible.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
