Description

FIELD OF THE INVENTION

The present invention relates to an interactive reproducing apparatus for content recorded on an information medium, and in particular, to a recording and / or reproducing apparatus configured to interactively reproduce audio video (SV) data, information, a method for controlling advanced AV (SUSV, ENAV) - a buffer installed in the recording device and / or playback, and the storage medium having information used to control the ENAV buffer in interactive mode.

BACKGROUND

There are Universal Digital Discs (DVDs, DVDs) on sale that support the interactive playback of Sound Video (AV) data interactively in a Personal Computer (PC, PC) environment, which are defined as interactive DVDs. An interactive DVD contains markup documents as interactive data to support interactive functions, as well as AV data that conforms to the generally accepted DVD-Video standard. AV data recorded on an interactive DVD can be displayed in two modes. One mode is a video presentation mode in which an AV image is displayed in the same form as a conventional DVD-Video. Another mode is an interactive mode in which the AV image and the markup document are displayed so that the AV image is embedded in the markup document. For example, where the AV data is the title of the movie, the corresponding movie is shown on the display in the AV image area, and various additional information (for example, film script, image series, etc.) is displayed in the remaining display area, except for the AV area -Images.

Additional information may be displayed in sync with the movie title (AV data). For example, when a specific actor appears, a markup document containing personal information about the actor’s background is requested and displayed. In addition, a markup document displayed interactively allows for user interaction. For example, if a user presses a button created on a markup document, information about information about the actor that appears on the AV image that is currently being played is displayed.

However, in consumer devices (e.g., a home DVD player) configured to play an interactive DVD (i.e., configured to support interactive mode), there is a problem with managing a buffer to provide an interactive mode. Figa and 1b are reference views for ease of explanation of the problem existing in the standard method.

1A, a standard Personal Computer (PC) 5 contains a main buffer 55 with a capacity of more than hundreds of megabytes (for example, 256 MB). PC 5 additionally contains a hard drive 56, as an additional buffer, with a size of more than tens of gigabytes (for example, 32 GB). Accordingly, when PC 5 attempts to receive data from the server 9 via the Internet, there are rarely cases where data is not received due to the limited size of the buffer 55 or 56 for storing data.

However, as shown in FIG. 1B, a home DVD player 2 connected to the TV 1 with which it is used has a smaller buffer size compared to PC 5. The buffer size is basically only a buffer of 25 out of tens of megabytes (for example, 32 MB ) Accordingly, when the home DVD player 2 attempts to access the server 9 via the Internet and receives the desired content, the home DVD player 2 cannot host the content if the server 9 provides the content using a method in which the content is stored in a buffer without restriction, as in PC 5.

DETAILED DESCRIPTION OF THE INVENTION

Now, reference is made directly to the presented embodiments of the present invention, the possible variants of which will be described in detail according to the attached drawings, in which through numbering is used. Embodiments are described below to explain the present invention according to the drawings.

As used in this description, “ENAV (Enhanced AV) Data” means all data to support interactive mode. For example, in the case where DVD-Video is played interactively, the interactive data is classified into a markup document and a markup resource inserted into the markup document. "Markup document" means all documents (for example, A.xml) that are created using markup languages, including XML, HTML, etc. "Markup Resource" means all A.png, A.jpg, A.mpeg, etc. files that are inserted into A.XML. In particular, the markup document acts directly as the application needed to play interactively the AV data, together with the inserted program codes, or together with the program codes provided as a separate external file, and at the same time acts as the ENAV data to be displayed along with AV data.

2 schematically depicts a recording and / or reproducing system according to an embodiment of the present invention. 2, a recording and / or reproducing system records and / or reproduces data with respect to the DVD 300, which is a storage medium in accordance with an aspect of the present embodiment. The system comprises a recording and / or reproducing apparatus 200 for use with a DVD 300, a television 100, which is a display according to an aspect of the present embodiment, and a remote control 400, which is a user data input device, according to an aspect of the invention. The remote control 400 receives a control command from the user and transmits the command to the recording and / or reproducing apparatus 200. The device 200 recording and / or playback accesses the Internet and transmits or receives the required ENAV data. A recording and / or reproducing apparatus 200 performs buffer control to support interactive mode using ENAV data in accordance with an aspect of the present invention. A detailed description of buffer management will be given below. Although the display is shown separately, it is understood that it can be integrated directly into the device 200, for example, for portable devices such as portable DVD players, personal digital assistants, portable phones, and other devices having an integrated display.

Also, the recording and / or reproducing apparatus 200 includes a DVD drive (not shown) for reading data recorded on the DVD 300, which is contained in the device 200 or is connected to the device 200. If the DVD 300 is loaded into the DVD drive and the user selects interactive mode, the recording and / or reproducing apparatus 200 reproduces interactively the corresponding AV data using the corresponding markup document, and transmits the reproduced result to the television 100. The television 100 displays unity picture from the markup picture obtained from the markup document and AV-image embedded in a markup picture. "Interactive mode" means a method for displaying AV data defined in a markup document in a window on a display screen, and more specifically, a method for displaying AV data such that an AV image is embedded in an interactive image. Here, the AV image represents a reproduced image of the AV data displayed on the television 100, and the interactive image represents an image displayed interactively (i.e., an image in which the AV image is embedded). "Video presentation mode" means a method for reproducing AV data in accordance with a method defined in standard DVD-Video (that is, a method for displaying only AV images obtained by reproducing corresponding AV data on a television 100).

In the present embodiment, the recording and / or reproducing apparatus 200 supports an interactive mode and a presentation mode of video images. However, it is understood that device 200 does not require support for both modes. In addition, it is understood that the DVD 300 may be optionally: read-only, non-rewritable or rewritable storage media that includes magnetic media, magneto-optical media, optical media such as CDs, etc., and a DVD of the following generation, which includes Blue ray discs, Advanced Optical Discs (AODs), or E-DVDs, flash memory, or other media. Additionally, it is not required that the user input device be a remote control 400, it can be a touch screen display, keyboard, mouse, or any device by which commands are entered. Although the display is described in terms of the television 100, it is understood that other types of displays may be used, such as display panels, plasma displays, liquid crystal displays and / or OLED devices. In conclusion, it is understood that the sound produced by the device 200 can be output through the speakers (not shown) contained in the device 200, or through speakers, headphones, or another audio output device connected to the device 200 for outputting audio data.

3 is a block diagram of a recording and / or reproducing apparatus 200 according to an aspect of the invention. 3, the reproducing apparatus 200 comprises an AV buffer 201, an ENAV buffer 202, an AV recording and / or reproducing mechanism 203, and an ENAV mechanism 204. The AV buffer 201 is a buffer for buffering AV data, and the ENAV buffer 202 is a buffer for buffering ENAV data. In the illustrated embodiment, the AV data is DVD-Video data recorded on the DVD 300 in accordance with the DVD-Video format. However, the AV data may have other formats, such as formats received from the Internet. In the depicted embodiment, ENAV data includes markup documents and / or markup resources. The AV buffer 201 and the ENAV buffer 202 may be separate memory chips or may be a single memory chip in hardware. Furthermore, although they are described in terms of video, it is understood that the AV data may be audio data such as DVD-Audio, image data, or video information, or other data that is read from a DVD 300 or other type of storage medium and reproduced from ENAV data interactively.

The AV playback engine 203 decodes and outputs the AV data. In the depicted embodiment, the AV reproduction mechanism 203 comprises an MPEG decoder adapted to decode VD-Video data. The ENAV mechanism 204 is an interpretation mechanism that interprets and executes ENAV data that must be combined and displayed with decoded AV data interactively. The ENAV engine 204 supports an interactive mode and a presentation mode of video images. From the point of view of the software used in the embodiment of the invention, the ENAV mechanism 204 comprises a markup document viewer that interprets and displays markup documents, a browser for receiving the required data from the Internet, and a markup resource decoder that decodes the markup resources. The output of the ENAV engine 204 and the output of the AV playback engine 203 are mixed to form an interactive image. An interactive image is displayed on the TV 100.

The applicant has filed many patent applications related to the various ways in which an AV image is embedded and displayed in an interactive image. For example, Korea Patent Application No. 01-33526, filed June 14, 2001 (registered in the United States as US Patent Application No. 10/170419), Korea Patent Application No. 01-64943, October 20, 2001 ., Korean Patent Application No. 01-65391, October 23, 2001 (registered in the United States as US Patent Application No. 10/277094), and Korean Patent Application, No. 02-50524, registered August 26, 2002 g. (registered in the United States as the application for US patent number 10 / 647445), which are incorporated by reference. Therefore, additional details regarding these methods are not given.

In addition, according to an aspect of the present invention, the ENAV mechanism 204 controls the ENAV buffer 202. That is, the ENAV mechanism 204, based on the configuration information of the ENAV buffer, allocates an area within the ENAV buffer 202 required to load the desired ENAV file containing the ENAV- data, as an updated markup area. Then, the ENAV engine 204 loads the corresponding ENAV file into the selected area. A file containing ENAV data is called an ENAV file. Also, the ENAV mechanism 204 controls the updated markup area of the ENAV buffer 202 in accordance with the configuration information of the updated markup area.

4 is a reference view for describing configuration information of an ENAV buffer according to an embodiment of the present invention. 4, the ENAV buffer 202 is logically and physically divided into two regions A and B. Region A is an updated markup area and is an area allocated for storing ENAV data, markup documents, and markup resources. Region B is a normal region and is used to store markup documents that do not require updating, for example, a file of a nested style sheet (PTS, CSS) that defines the style of a markup document, script file, image file, font file, etc. That is, the configuration information of the ENAV buffer includes information regarding the size of the updated markup area in the ENAV buffer 202. The remaining area, except for the specified size, is a normal area. Therefore, since the ENAV buffer 202 includes an updated markup area, in spite of the small size of the memory of the ENAV buffer 202, an Internet service can be provided (for example, an online correspondence service) described later.

Further, as a detailed embodiment, an interactive correspondence service provided using an updated markup area is described. However, it is understood that other Internet services may be used in place of or in addition to the online correspondence service.

5 illustrates the space of a DVD volume 300 according to an embodiment of the present invention. 5, the volume space of the DVD 300 includes a File and Volume management information area, an AV data area, an ENAV data area, and other data area. The file and volume management information for the entire DVD 300 is stored in the file and volume management information area. The video image headers, VIDEO_TS.IFO, VTS_01_0.IFO, VTS_01_1.VOB, etc., with each title being AV are stored in the AV data area - data recorded in accordance with the DVD-Video format. VIDEO_TS.IFO is a file that contains playback control information for all the headers of the video image. VTS_01_0.VOB, VTS_01_1.VOB and similar files are files for creating a set of video image headers (i.e. video image objects (OVI, VOB)). Each VOB contains a video image object module (VOBU), including a motion (navigation) packet, a video image packet, and an audio data packet. The detailed structure of the VOB is disclosed in the DVD-Video standard “DVD-Video for Read Only Memory disc 1.0”, which is incorporated by reference, and is therefore not repeated.

The ENAV data area stores ENAV data to support interactive mode. That is, a markup document, such as STARTUP.MLS, is stored in the interactive data area, for displaying it first, when selecting an interactive mode, a download information file such as LoadingInformation.LDI containing configuration information of the updated markup area and configuration information of the ENAV buffer, according to an aspect of the present invention. In the interactive data area, markup document files such as CHATTITLE.HTM and CHATROOM.HTM are additionally stored to provide an interactive correspondence service. Additionally, the interactive data area includes markup resources such as C1.PNG, C2.PNG, .... Files containing other data are stored in the other data area.

6 illustrates a directory structure of a DVD 300 according to an embodiment of the present invention. 6, the root directory contains a video image directory VIDEO_TS, including AV data. The VIDEO_TS video image directory includes the VIDEO_TS.IFO file, which stores movement information for the video image headers, the VTS_01_0.IFO file, which stores the movement information for the first set of video image headers, and the VTS_01_0.VOB, VTS_01_1.VOB, ... files for Create a set of video image headers. The root directory also includes an interactive directory DVD_ENAV, which stores information to support interactive mode. The DVD_ENAV interactive directory includes a STARTUP.MLS markup document to be displayed with a video title, a DownloadInformation.LDI download information file containing update markup area configuration information and ENAV buffer configuration information according to aspects of the present invention, CHATTITLE.HTM markup documents, and CHATROOM.HTM to provide online chat services and markup resources C1.PNG, C2.PNG.

7 depicts a possible variant of the start file STARTUP.MLS according to a variant implementation of the present invention. 7, the STARTUP.MLS startup file, as a markup document created using a markup language, includes a “loadinginfo” element. Label C indicates the portion of STARTUP.MLS that links the download information file to the startup file using the "loadinginfo" element. That is, the “loadinginfo” element associates the loading information file Loadinglnformation.LDI shown in FIG. 8, which includes location information for the required ENAV files, with a startup file for downloading the required ENAV files to be played interactively. As described above, the download information file includes configuration information of an ENAV buffer according to an aspect of the present invention.

Fig. 8 shows a possible embodiment of a loading information file Loadinglnformation.LDI according to an embodiment of the present invention. According to Fig. 8, in the depicted loading information file Loadinglnformation.LDI, the label D indicates the part in which the configuration information of the ENAV buffer is stored using the memory element. The memory element is an empty element without nesting other elements and has two attributes to indicate the name of the memory area and the size of the memory. The attributes depicted are the attribute "name" and the attribute "size". The name attribute identifies the name of a memory region. As depicted, “um” indicates an updated markup area. The size attribute indicates the size of the memory area. The size of the memory area depends on the size of the ENAV buffer 202. For example, if the ENAV buffer 202 is 36 MV, the memory region may have a size from 0 bytes to 36 MV. It is understood that attributes can be provided differently and that in all aspects of the invention, the name can be any name and is not required to be “um”.

In the illustrated embodiment, the name attribute is um and the size attribute is 6KB. Accordingly, the depicted memory element indicates that a 6KB ENAV buffer 202 is allocated for the updated markup area designated as um. The remaining area is a normal area.

Further, information on the names and locations of ENAV files that are to be loaded into the buffer 202 in advance is stored in the download information file, in accordance with an aspect of the invention. In the illustrated embodiment, files to be downloaded in advance are files for providing an online chat service. The file to be displayed first for the online chat service is represented by the CHATROOM.HTM markup document using the “initial” element. The remaining required files are represented, respectively, by markup documents CHATTITLE.HTM, C1.PNG, C2.PNG, INPUT.HTM, P1.GIF, DIALOG.HTM and DIALOG.CSS using the "entity link" elements. Here, you can see that the markup documents CHATTITLE.HTM, C1.PNG and C2.PNG are stored on the DVD 300. It is also shown that the markup documents INPUT.HTM, P1.GIF, DIALOG.HTM and DIALOG.CSS are stored on the Internet server 90, depicted in FIG. 13, hosted at “http://www.company.com”. In particular, you can notice that the markup documents DIALOG.HTM and DIALOG.CSS are loaded into the updated markup area, since these files are designated for the um section of the ENAV buffer 202.

FIG. 9 depicts a possible interactive chat screen for the interactive chat service supported by the recording and / or reproducing apparatus 200 according to an embodiment of the present invention. According to Fig. 9, the interactive correspondence screen has a dialogue window that displays the contents of the dialogue between users participating in the interactive correspondence, and a data input window into which one party participating in the interactive correspondence enters its texts. If the user enters his texts into the data entry window and clicks the send button <send> created on the interactive correspondence screen, the recording and / or reproducing device 200 sends the texts to the server 90 shown in Fig. 13, which provides an interactive service correspondence over the Internet. The recording and / or reproducing device 200 displays an updated markup document, and accordingly, the texts just entered by the user are displayed in the dialog box.

Figures 10-12 depict possible markup documents for the interactive chat screen of Figure 9. 10, a CHATROOM.HTM markup document is stored on the DVD 300 and is a markup document to be displayed first when a user selects an online chat service. The CHATROOM.HTM markup document is associated with the CHATTITLE.HTM markup document that is stored on the disc 300 for displaying an interactive correspondence header, and is also associated with the DIALOG.HTM markup document that is stored on the server 90 shown in FIG. 13, located in http://www.company.com, which provides an online chat service and is often updated to display a dialog box. According to FIG. 11, the DIALOG.HTM markup document is updated each time a user enters their texts and indicates that this markup document is provided from the server 90 of FIG. 13, which is located at http://www.company.com. 12, an INPUT.HTM markup document is provided from the server 90 of FIG. 13, which is located at http://www.company.com, for displaying a data input window on an interactive correspondence screen.

13 is a view for explaining a communication process between a recording and / or reproducing apparatus 200 and a server 90 for providing an online chat service according to an embodiment of the present invention. 13, a recording and / or reproducing apparatus 200 comprises an ENAV buffer 202 of a predetermined size. Server 90 provides an online messaging service for the recording and / or reproducing apparatus 200. Recording and / or reproducing apparatus 200 and server 90 communicate in accordance with a client-server model. In this embodiment, the communication is in accordance with the Hypertext Transfer Protocol (TCP), TCP / IP protocol based on the client-server model. However, it is understood that other client-server models and / or protocols may be used.

If the recording and / or reproducing device 200 accesses the server 90 and requests using the GET (communication operation (1)) DIALOG.HTM markup document to display a dialog box, then the server 90 transmits the requested document to the recording and / or reproducing device 200 markup DIALOG.HTM (operation (2) communication). It is understood that the recording and / or reproducing apparatus 200 may use the PUSH command instead of the GET command. Similarly, if the recording and / or reproducing apparatus 200 requests, using the GET command (communication operation (3)), the INPUT.HTM markup document for displaying the data input window and requests the P1.GIF marking resource (communication operation (4)), then the server 90 transmits the requested INPUT.HTM markup document and P1.GIF markup resource (communication operations (5) and (6) to the recording and / or reproducing apparatus 200.

Meanwhile, when updating the required file (markup document and / or markup resource), the server 90 creates a corresponding file having a size no larger than the size of the buffer allocated for the corresponding file, as will be described below, so that the recording and / or reproducing device 200 can correctly receive updated file.

Figures 14 and 15 depict possible variations of the operations (1) and (2), respectively, during the communication process illustrated in Fig. 10. Fig. 14 depicts a possible case for receiving a DIALOG.HTM markup document for displaying a dialog box on an interactive correspondence screen using a LOADINFO.LDI download information file containing ENAV buffer configuration information. 14, operation (1) depicts the configuration of the request header to enable the device 200 to transmit the recording and / or playback to the server 90 of the GET command in accordance with the HTTP protocol (i.e., the REQUEST Header). In particular, the “User Agent” indicates the type of recording and / or reproducing device 200, and the “Referer:” indicates that the document referencing the DIALOG.HTM markup document is a file LOADINFO.LDI buffer configuration information, which is stored in the DVD 300 interactive directory.

Operation (2) is the configuration of the response header transmitted from the server 90 in response to the GET command from the playback device 200 as a client, in accordance with the HTTP protocol (i.e., the RESPONSE Header). In particular, “Last-modified:” may indicate that the DIALOG.HTM markup document is a document updated on the server 90 (i.e., a mutable document). Accordingly, if “Last-modified:” is not included in the RESPONSE Header from the server 90, then the recording and / or reproducing apparatus 200 may consider the corresponding markup document or the corresponding markup resource as an unchangeable document.

Fig. 15 shows a possible case for receiving a DIALOG.HTM markup document for displaying a dialog box on an interactive correspondence screen using the CHATROOM.HTM markup document. Operation (1) depicts the configuration of the request header to enable the device 200 to transmit the recording and / or playback to the server 90 of the GET command in accordance with the HTTP protocol (i.e., the REQUEST Header). In particular, the “User Agent” indicates the type of recording and / or reproducing device 200, and the “Referer:” indicates that the document referencing the DIALOG.HTM markup document is a document markup CHATROOM.HTM, which is stored in the interactive directory DVD 300. Operation (2) depicts the configuration of the response header transmitted from the server 90 in response to a GET command from the playback device 200 as a client, in accordance with the HTTP protocol (i.e., RESPONSE Header) . In particular, “Last-modified:” may indicate that the DIALOG.HTM markup document is a document updated on the server 90 (i.e., a mutable document). Accordingly, if “Last-modified:” is not included in the RESPONSE Header from the server 90, then the recording and / or reproducing apparatus 200 may consider the corresponding markup document or the corresponding markup resource as an unchangeable document. As shown in operation (2) of FIG. 15, “Last-modified:” indicates a document change after operation (2) of FIG. 14, indicating that the document to be changed in the selected area should be updated.

16 is a view showing configuration information of an updated markup area determined based on configuration information of an ENAV buffer according to an embodiment of the present invention. According to FIG. 16, configuration information of an updated markup area is information recorded on a DVD 300 (in this embodiment, included in a download information file for an online chat service). The configuration information includes ENAV file location information and buffer area size information that will be allocated to the corresponding ENAV files. Also, the configuration information of the updated markup area may further include information indicating the formats of the respective ENAV files, and information indicating whether the corresponding ENAV files are updated in the server 90. However, it is understood that the configuration information may contain additional information.

Fig.17 depicts the configuration of the updated markup area corresponding to the configuration information of the updated markup area of Fig.16. 17, in the ENAV buffer 202, buffer areas are allocated in accordance with the configuration information of the markup area of FIG. 16. More specifically, since the size of the buffer to be reserved for DIALOG.HTM, which is stored at http://www.company.com/DIALOG.HTM, is 5 KBytes, a buffer area of 5 KBytes is allocated for DIALOG.HTM. Also, since DIALOG.CSS is stored at http://www.company.com/DIALOG.CSS, a buffer area of 1 KBytes is allocated for DIALOG.CSS. Since there is no information about the buffer size for INPUT.HTM and P1.GIF, which are stored, respectively, at http://www.company.com/INPUT.HTM and http://www.company.com/P1.GIF, then the buffer areas for INPUT.HTM and P1.GIF are determined by the server 90. Server 90 can allocate the size of the transmitted file through the 'Content-length:' ('Content-length:') RESPONSE header, as described above, according to FIGS. 14 and 15.

File: //DVD_ENAV/CHATROOM.HTM, file: //DVD_ENAV/CHATTITLE.HTM, file: //DVD_ENAV/C1.PNG and file: //DVD_ENAV/C2.PNG indicate that the corresponding files are CHATROOM.HTM, CHATTITLE. HTM, C1.PNG and C2.PNG are stored on the DVD 300, respectively. Therefore, file buffer areas are allocated by the file system of the recording and / or reproducing apparatus 200 in accordance with a plurality of file sizes.

Below, according to FIGS. 18 and 19, buffer management methods according to embodiments of the present invention are described based on the configuration described above.

Fig. 18 is a flowchart for explaining a buffer control method according to an embodiment of the present invention. 18, when the DVD 300 is loaded into the recording and / or reproducing apparatus 200 and the user selects an interactive mode, the reproducing apparatus 200 opens the STARTUP.MLS startup file included in the DVD_ENAV directory and reads the loading information file LoadingInformation.LDI containing the ENAV configuration information a buffer according to an aspect of the present invention that is associated with the STARTUP.MLS startup file, in operation 1801. The recording and / or reproducing apparatus 200 checks the configuration information of the ENAV buffer through the download information file, in operation 1802, and updated wish to set up a domain markup ENAV-buffer 202 corresponding to the checked result in step 1803. As described above, the remaining area ENAV-buffer 202 is a normal region.

Fig. 19 is a flowchart for explaining a buffer control method according to another embodiment of the present invention. As shown in FIG. 19, when a user selects an online correspondence service, the recording and / or reproducing apparatus 200 interprets the startup file recorded on the DVD 300 and reads the download information file containing the configuration information of the updated markup area as configuration information of the ENAV buffer to provide the selected online chat service (operation 1901).

The recording and / or reproducing apparatus 200 determines by information included in the download information file whether there is a file to be loaded into the ENAV buffer 202 (operation 1902). If the file to be loaded into the ENAV buffer 202 does not exist, then the reproducing apparatus 200 interprets the document to be displayed on the screen initially and displays the interpreted document on the screen (operation 1903).

If a file to be loaded into the ENAV buffer 202 exists, then the recording and / or reproducing apparatus 200 determines whether a file size has been set (operation 1904). If a file size has been set, then the recording and / or reproducing apparatus 200 reserves a buffer region corresponding to the set file size (operation 1906). If the file size has not been set, then the device 200 recording and / or playback detects the location of the file (operation 1907). If, in accordance with the detected result, the file is stored on the DVD 300, then the recording and / or reproducing apparatus 200 reserves a buffer region corresponding to the size determined by the file system (operation 1908). For example, the file system may have information about the name, attribute and size of the file, so that the size determined by the file system indicates the size of the file that is stored on the DVD 300. If, in accordance with the detected result, the file is stored on the server 90, then the device 200 recording and / or playback reserves a buffer region corresponding to the size determined by the server 90 (operation 1909).

When the buffer region is reserved in operation 1910, the recording and / or reproducing apparatus 200 loads the corresponding file into the reserved buffer region (operation 1911). If the buffer region is not reserved, then the recording and / or reproducing apparatus 200 transmits a message indicating that the buffer region is not reserved, and the process ends (operation 1912). Finally, if while the user searches for the markup document, a request is generated requesting other buffer configuration information, the process returns to operation 1902 and the above operations are repeated for other buffer configuration information.

If the user searches for the markup document and determines that DIALOG.HTM is updated on the server 90, then the recording and / or reproducing apparatus 200 receives the updated DIALOG.HTM from the server 90. If the server 90 controls the size of the updated markup document so that it is within the predefined buffer size (in the possible case mentioned above, 5 KBytes), then when updating the markup document (and / or markup resource), the recording device 200 and / or playback can correctly process and display the updated content without causing errors due to lack of buffer. In addition, if when searching for a markup document, a request is generated requesting other memory configuration information, then the recording and / or reproducing apparatus 200 returns to operation 1902 and repeats the above operations.

The buffer control methods illustrated in FIGS. 18 and 19 can be implemented in a universal or specialized digital computing device by executing a program encoded on a medium readable by a computer that is read by a computer. Computer-readable media includes a storage medium such as a magnetic storage medium (e.g., ROM devices, floppy disks, hard drives, etc.), an optical-readable storage medium (e.g., CD-ROMs, DVDs, Next-generation DVDs, such as Bluray discs and AOD discs, rewritable and non-rewritable media, etc.), magneto-optical media and carrier (for example, transmission over the Internet), etc. It is understood that the connection to the server 90 can be made, instead of or in addition to the Internet, through various networks, including radio networks, a local area network (LAN), a wide area network (WAN), private intranets, etc. Additionally, although ENAV files are described as being located on server 90, it is understood that ENAV files can be stored on any external media connected to device 200 for providing ENAV files. Finally, although the division into two regions is depicted, it is understood that the ENAV buffer 202 can be allocated so that more than two regions exist.

As described above, according to aspects of the present invention, when a server provides the desired content to a recording and / or reproducing apparatus as a consumer device supporting interactive mode, there is the possibility of adaptively controlling the size of the contents in accordance with the buffer size of the reproducing and allocating memory device using the method decisions in the recording and / or reproducing device, which is a consumer device with a limited buffer size, so that the playback device Institution redundant buffer area for ENAV-file in advance, before taking out the ENAV file-server. Accordingly, the ability to display markup documents and / or markup resources that are freely updated on the Internet exists only if the content provider creates and provides content smaller than a predetermined size in accordance with the memory configuration information.

INDUSTRIAL APPLICABILITY
