In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below and described in detail in conjunction with the accompanying drawings as follows: Embodiments ... The drawings illustrate a preferred embodiment of the present invention in detail. The terms used in the description have the following meanings. A "markup file" represents a markup file and a markup source file including various image files and image files inserted in the markup file. "Scene file scene" represents the scene that "tag file" is displayed by the viewer. "AV scene" represents a scene in which AV data is decoded and displayed. Scene composition information represents information in the definition of a method for displaying a markup file and an AV scene together according to the present invention. FIG. 1 is a block diagram of a DVD reproduction apparatus according to a preferred embodiment of the present invention. Referring to FIG. 1, according to this embodiment, the playback device displays the AV scene and the mark file scene obtained by decoding the AV data and the mark file recorded on the optical disc 100 in the interactive mode according to the display method of this embodiment. The playback device includes a reading unit, an AV decoder 2, a display engine 3, and a blender 4. The reading unit 1 reads the AV data from the optical disc 100, marks the file and scene composition information, and provides the read AV data, the mark file and scene composition information to the AV decoder 2 and the presentation engine 3. In addition, the reading unit 1 may include a buffer memory (not shown) and a cache memory (not shown) to buffer the read AV data and cache the read mark files, respectively. The presentation engine 3 supports a display mode according to the present invention. From the point of view of the software list 10734pif doc / 〇〇8 12 200304646, the display engine 3 includes: an application program as an operating system interface of a regeneration device through an application program interface (API); and a terminal interpretation engine. APIs are established special methods that require operating system processing or another application. The terminal interpretation engine is implemented by an interpretation engine written in JavaScript or Java, which interprets a program written in JavaScript or Java, such as a web browser, and executes the program. Even more, the display engine 3 includes a plug-in. The plug-in enables files of various formats included in the markup document or files called by the markup document to be opened. The presentation engine 3 interprets the scene synthesis information according to the present invention, and transmits the decoding instruction and the display instruction to the AV decoder 2 and the mixer 4 respectively according to the interpretation result. The AV decoder 2 decodes the AV data according to the provided decoding instruction and outputs the decoded AV data to the mixer 4. The mixer 4 displays the mark file scene and the AV scene together according to the display instruction. To execute the reproduction method according to the embodiment of the present invention, the presentation engine 3 calls a style sheet linked to or embedded in a markup file manufactured by the reading unit 1 and interprets the style sheet. Information on the method of synthesizing the mark file scene and the AV scene is described in this style sheet. In order to execute the reproduction method according to another embodiment of the present invention, the display engine 3 interprets the screen mode (aspect ratio, resolution, and image output mode) set by the playback device or the user, and uses presets set by the playback device. The style sheet or the style sheet provided by the manufacturer outputs an instruction according to the set screen mode (especially, use viewport: to specify the adjustment area of the scene where the AV scene and the mark file scene are combined with each other; use window: to specify the AV A screen window combining the scene and the mark file scene with each other. Use 10734pifdoc / 008 13 200304646 and use video-viewport: to specify the area where the required portion of the AV scene is increased or decreased). In addition, the switching unit may be included in the AV decoder 2. When the egg screen is set to a 4x3 size, the AV decoder 2 converts the AV stream into a letter-box or pan & scan format and outputs the converted AV stream. When the screen is set to 16x9, AV decoder 2 outputs the AV stream in 16x9 without conversion. This is because in a DVD playback device, an AV stream is generally encoded into a 16x9 size. However, when the display mode in the interactive mode is an embedded mode or a picture-in-picture (PIP) mode, the AV decoder 2 sets the "initial display aspect ratio" in the display engine 3 according to the initial setting preferred by the user. ", Can output AV stream in 16x9 size without converting the AV stream to subtitle or pan & scan form, and even display it on 4x3 screen. That is, preferably, when 16x9 AV data is displayed on a 4x3 screen, the display engine 3 controls the AV decoder 2 to output 16x9 size AV data in the embedded mode or PIP mode of the interactive mode, and in the interactive mode In background mode or image mode, AV data is output in pan & scan or subtitle format. However, the AV data transmitted by the AV decoder 2 can be output in the pan & scan or subtitle form in the embedded mode or the PIP mode of the interactive mode. In order to execute the reproduction method according to another embodiment of the present invention, the display engine 3 only interprets the document-viewport: and d0cument_window: of the markup files defined in the scene synthesis information, and the video-viewport: and vide0- of the AV data, respectively. window :. In order to execute the reproduction method according to another embodiment of the present invention, different from the AV decoder 10734pifdoc / 008 14 200304646 2 with a switching unit, even if the screen is set to 4x3 size, in the embedded mode or PIP mode, no additional switching is included The unit's AV decoder 2 outputs a 16x9 AV stream with the screen set to a 16x9 size according to the decoded viewport and window of the tagged file and the AV data view and window. It does not output an AV stream at Subtitle or pan & scan format. Figure 2 is a reference diagram of the screen alignment sequence (Z direction) of the display (not shown) of the device connected to Figure 1. Referring to Figure 2, the final scene shown to the user is obtained by actually adding the four scenes. The scene 21 showing the index is placed first, followed by the markup file scene 22 based on the markup file, the AV scene 23 based on the AV data, and the background scene 24 generally displayed in a single color. FIG. 3 shows a file structure of the DVD 100 according to FIG. 1 of a preferred embodiment of the present invention. Referring to Figure 3, the video directory VIDEO_TS including AV data and the interactive directory DVD-ENAV including data supporting interactive functions (such as markup files) are provided in the root directory. AV data and reproduction control information (also called navigation data) are recorded in the video directory VIDEOJTS. The reproduction control information includes reference information for decoding Av data. Marker files and scene composition information are recorded in the interactive directory dvd_enav. In particular, the file VIDEO-TS.IFO, which records header information about the complete video name, has been recorded in the video directory video TS. Secondly, a file VTS—01—O.IFOg recording header information about the first image name has been recorded in the image directory vIDE〇—TS, and then a file VTS 01_0 · ν〇Β of the AV data constituting the image name '10734pifdoc / 008 15 200304646 VTS — 01_1.VOB ... is recorded in the video directory VIDEO_TS. A more detailed structure is revealed in the DVD-video specification "DVD-Video for Read Only

"Memory disc 1.0". The reproduction control information file DVD_ENAV.IFO which records the header information about the complete data supporting the interactive function is recorded in the interactive directory DVD_ENAV. Only DVD_ENAV.IFO is available to perform the start function g tag files are replaced by various meta tags. Second, the tag file A.HTM is recorded in the interactive directory DVD-ENAV, and the style sheet a.CSS and the scene synthesis information on it are recorded in the interactive directory DVD_ENAV. In addition, the mark files B.HTM and C.HTM are recorded in the interactive directory DVD_ENAV. The image file a.PNG inserted and displayed in the mark file A.HTM; the image inserted and displayed in the mark file B · ΒΤΜ Files B1.PNG and B2.PNG; and image files C.PNG g inserted and displayed in the markup file C.HTM have been recorded in the interactive catalog DVD-ENAV. Various types of other marks inserted and displayed therein Files and archives can be recorded in the interactive directory DVDJENAV. Figure 4 shows a picture in picture (PIP) mode according to one of the display modes of this embodiment. Referring to Figure 4, in the PIP mode, the AV scene is treated as PIP And the output Overlaid on the mark file scene. Only this mark file scene is actually placed in front of the AV scene, as described with reference to Figure 2. From the user's point of view, the PIP mode makes the AV scene overlap the mark file scene. Preferably, the PIP mode is subdivided by the placement position and size of the AV scene. In this embodiment, the PIP mode is initially used with several types such as PIP-1 and PIP-2. In the PIP mode, 10734pifdoc / 008 16 200304646, the user can use the remote control (not shown) to change the position and size of the AV scene. However, one of the xML codes that make up the mark file A.HTM in Figure 4 is as follows. _ ≪ ? xml version = ”1 0 ''? 〉 ≪!

A.HTM Obviously, the style sheet file A.CSS uses link tags to link to the above source code. One example of the source code of the style sheet is as follows. 17 10734pifdoc / 008 200304646 @ screen-display {video-placement: PIP background-co lor: # 00000 000 viewport: rect (0px, 719ρχ, 479ρχ, 〇ρχ) window: rect (0px, 719px, 479px, 〇px) video -viewport: rect (0px, 719px, 479px, 0px)

A.CSS In this embodiment, the cascading style sheet (css) uses the @screen_display rule as described above to use the display mode between the marked file scene and the AV scene. Describe some features, such as: video_placement :, which is used to specify the display mode of the AV scene; background_color :, which is used to specify the background color of the AV scene; viewport :, which is used to specify that the AV scene is synthesized into the tag file scene The adjustment area of the scene; window: it is used to specify the window where the AV scene is synthesized into the scene of the mark file scene; video-viewport: it is used to specify the area where the required portion of the AV scene is to be increased and decreased. Fig. 5 shows an embedded mode, which is one of the display modes according to this embodiment. Referring to FIG. 5, in the embedded mode, the AV scene is embedded in the markup file through <〇1) ″ 6 (^-&gt;. Therefore, the position and size of the AV scene can be in the markup file. Move and change under control. In this embedded mode, the AV scene is embedded and displayed in the display window defined by the markup file.

Here, the set of "shape" is a rectangle (&lt; top &gt;, &lt; right &gt;, &lt; bottom &gt;, &lt; left &gt;) 〇21 10734pifdoc / 008 200304646 Brother 7 figure is specially shown according to video- viewport: A reference picture of the AV scene and video file display mode with video-placement ... Refer to Figure 7 'If the area a used to increase and decrease the AV scene is specified by video-viewport :, when video-placement: is the background mode, the adjustment area a is displayed in the background scene; the file scene is marked (not shown) (Out) is not displayed in the adjustment area a. When video-placement: is in PIP mode, the adjustment area a is displayed in the specified position. When videoplacement: is in PIP mode, the adjustment area a is embedded in and displayed in the display window defined by the markup file. Fig. 7 shows an example of selecting only a part of the area of the AV data, that is, the area of video-viewport: is selected as a part of the area, so that the part of the area maps to the area of window: defined by each display mode. Fig. 8 is a reference drawing showing the AV scene of the viewport: and window: and the display mode of the mark file. In the selection feature 値 viewport: to display the AV scene synthesized on the scene of the mark file scene, adjust the area of the scene content on the screen and select the feature to specify the window area 値 window .. Make all or part of the selected file In the predetermined scene area displayed on the screen, one of viewport: and window: can be used without change. However, Fig. 8 shows that only a part of the scene where the AV scene is synthesized in the scene of the mark file scene is selected, that is, the area of the video-viewport: is selected as the part area, so that the part area is mapped to the definition of each display mode Window: the area. The idea of viewport: and window: allows AV scenes to be added to or subtracted from some or all of the scenes that are marked up in the file. Referring to Figure 8, in the embedded mode where the AV scene is embedded in the markup file scene and displays 10734pifdoc / 008 22 200304646, if the AV scene is synthesized in the scene of the markup file, the adjustment area b of the scene is specified by viewport :, the adjustment area b Displayed in the window specified by window :, as shown in (2). If the background of the subject label is specified, the entire scene is displayed in the window specified by window :. It is used to specify the characteristics and variables of the display mode. It is used to specify the characteristics and variables of the background color of the AV scene. It is used to specify the characteristics and variables of the window of the AV scene synthesized in the scene of the markup file scene. The features and variables of the adjustment area of the scene of the document scene, and the features and variables of the area used to specify the required portion of the increase and decrease of the AV scene are defined in the object that controls the above CSS file. In addition, using the object source code of the application program interface (API) of the document object model (DOM), the AV scene can be increased / decreased according to user input. For the source code of the object required to perform this action, please refer to the script language in the markup file.

&lt; / taWe &gt; &lt; / b〇dy &gt; In this way, the ratio of AV scenes can be manipulated by user input using the DOM's API and thread language. Therefore, according to the above embodiment, the AV scene and the mark file scene can be freely synthesized, and the display position of the AV scene can be set by linking to the mark file or a style sheet embedded in the mark file, thus allowing users to enjoy different types of scenes. The regeneration method of the present invention will be described below based on the above structure. Fig. 9 shows a flowchart of a reproduction method according to a preferred embodiment of the present invention. Referring to FIG. 9, in step 910, the reading unit 1 of the reproduction device reads the mark file to be reproduced together with the AV data from the optical disc 100. In step 902, the display engine 3 interprets the read mark file, and in step 903, the display engine 3 calls a link to the style sheet file of the mark file. Next, in step 904, the presentation engine 3 interprets the style sheet file and provides the interpretation result to the AV decoder 2. Specifically, the display engine 3 reads from the disc 100 the display mode designation information described in the style sheet file to specify the display mode of the AV scene; the background color designation information used to specify the background color of the AV scene; Specify the scene of the AV scene synthesis mark file to be displayed in the window on the display screen 10734pif doc / 008 26 200304646 Window designation information; used to specify the adjustment of the synthesized scene of the adjustment area of the scene of the AV scene synthesis mark file Area designation information; and AV adjustment area designation information for designating an area for increasing and decreasing a required portion of an AV scene. The AV decoder 2 decodes the AV data according to the style sheet file and outputs related AV scenes to the mixer 4. The display engine 3 outputs an instruction to display the markup file scene and the AV scene according to the description in the style sheet file, and the markup file scene with the markup file reproduced therein to the mixer 4. To this end, the presentation engine 3 interprets a program that encodes and controls the style sheet file according to an object having characteristics and variables that can control the style sheet file. The mixer 4 mixes and outputs mark files and AV scenes provided by the presentation engine 3 and the AV decoder 2, respectively. In step 905, the AV scene and the mark file scene are displayed according to the decoded scene composition information. In step 905-1, when the PIP mode is described in the style sheet file, the AV scene is superimposed on the mark file scene and displayed. In step 905-2, when the embedded mode is described in the style sheet file, the AV scene is embedded in the markup file scene and displayed. In step 905-3, when the background mode is described in the style sheet file, the mark file scene is superimposed on the AV scene and displayed. FIG. 10 shows a flowchart following step 903 of FIG. 9. Referring to FIG. 10, the display engine 3 interprets the CSS file or link tag in the markup file in step 1001 and calls the CSS file; interprets the called CSS file in step 1002; and reads the description in step 1003 The display mode designation information and AV adjustment area designation information in the CSS file. In step 1004, the mixer 4 combines and outputs 10734pifdoc / 008 27 200304646 of the display engine 3, where D = 丨 tells the mark file scene and the field provided by the Av decoder 2 and marks the file scene and Αν scene according to the theta described in the CSS file; display mode. In the case where no mode is specified, the AV scene is displayed in step 1004-1. Otherwise, one of the PIP mode (step 1004-2), background mode (step 1㈧4-3), and embedded mode (step 104_3) will be displayed. Fig. 11 is a flowchart showing a recording method according to a preferred embodiment of the present invention. Referring to FIG. 11, the recording device records the AV data in the information storage medium (step 1101); records the mark file to be reproduced with the AV data in the information storage medium (step 1102); and the recording link is embedded in or embedded in the delta The scene composition information in the style sheet file in the markup file is marked (step 1103). In step 1103, an object having the characteristics and variables of the style sheet file in the control mark file and a program for controlling the style sheet file according to the object are recorded in the information storage medium. Up to now, in the described embodiment, the scenes marked with scenes synthesizing AV scenes use features of scene synthesis information 値 window: and viewport: to increase power [] / decrease, and some AV scenes use features 値 video-viewport: To increase the power of Π / decrease, the AV material and the mark file are displayed in various ways in the interactive mode. The following will describe the use of the characteristics of the above scene synthesis information: window: and viewport :, and according to the resolution and aspect ratio (screen ratio) set by the messenger or set in the playback device, the AV is displayed in various ways in interactive mode. Information and methods for marking documents. When a markup document with a fixed screen ratio is to be displayed on a screen with a different aspect ratio when it is produced, the scene distortion phenomenon that some data such as text or images are to be displayed on the screen will be incorrectly displayed 10734pifdoc / 〇〇8 28 200304646 will happen. Therefore, in the present invention, the feature 値 window: and viewport: are used to change the interactive content that is fixed at a certain screen ratio to a different screen ratio at the time of manufacture. The degree of scene distortion is minimized to meet the needs of users. The screen mode (aspect ratio, resolution, and image output method) set or set in the playback device. First, a method of displaying interactive content made using a markup language on several screens with different screen aspect ratios to minimize distortion of the interactive content will be described with reference to FIG. 12. For ease of interpretation, the ratio of pixel sizes in all cases is set to 1x1. The first display method: the manufacturer considers several screen aspect ratios to prepare individual markup files and individual AV data to match 7K screens with different aspect ratios. In order to display the interactive content that will not be distorted on the pictures with different aspect ratios as shown in (1) and (2), the manufacturer considers the aspect ratios of the different pictures as shown in (3) and (4) and prepares them separately. Mark the files and prepare separate AV data (ie, DVD-video-sized AV content) considering the aspect ratios of the different pictures as shown in (5) and (6). (3) + (5) can be displayed on the screen of 4x3 screen shown in (1), and the 16x9 AV data can be synthesized on the 16x9 tag file. (4) + (6) The content can be displayed on the 16x9 screen shown in (2). As the manufacturer envisions, no special operation is required. The second display method: The manufacturer prepares individual markup files in consideration of the aspect ratio of the screen. When the content with a fixed aspect ratio is produced in the following manner, the AV data is about the screen with a different aspect ratio. 10734pifdoc / 008 29 200304646 When only (3), (4), and (5) are manufactured-when displayed on a 4x3 screen, the 4x3 AV data is combined into a 4x3 tag file to obtain (3) + (5) The content can be displayed on the screen of the 4x3 screen shown in (1), as the manufacturer envisions, without any special operations. -When displaying on a 16x9 screen, embed the 4x3 AV data (5) in a 16x9 mark file including the right and left blank areas without expansion. By setting the size of the object tag of the 16x9 tag file, it is necessary to eliminate the right and left blank spaces, so that the 4x3 AV data can be embedded in the 16x9 tag file. The content of (4) + (5) can be displayed in scene (2), as the content envisioned by the manufacturer, without any special operation. When only manufacturing (3), (4) and (6)-when displayed on a 4x3 screen, 16x9 AV data (6) is converted to 4x3 normal scene, 4x3 subtitle scene or 4x3 pan &amp; scan scene , And then embedded in a 4x3 markup file (3). (3) + (6) The content can be displayed in scene (1), as the content envisaged by the manufacturer, without any special operation. Here, the full screen scene is called a standard scene and is manufactured and reproduced in a 4x3 aspect ratio (1.33: 1). The fully normal scene is displayed on a 4x3 screen. Black bands appear at both ends of a 16x9 screen scene. If the user views the entire scene on a 16x9 screen (wide mode (a) in Figure 13), the pattern appears to expand horizontally, and if viewing the scene in zoom mode, the upper and lower parts of the scene are cut off. In both cases, only the pattern is added, so the resolution will be lower. Pan &amp; Scan is a picture obtained by cutting two 10734pif doc / 008 30 200304646 images made into a square scene (16x9) side and selecting only the central part of the scene with a 4x3 aspect ratio (1.33: 1) For example, as shown in (b) of FIG. 13, the reproduction pan &amp; scan method is the same as the full screen reproduction method. The advantage of subtitle scenes is that users can enjoy scenes as shown in a movie theater, but its disadvantage is that the scene size is reduced. In the Pan &amp; Scan method, both ends of the unimportant scene are cut off, and the image fills the 4x3 scene instead of reducing the scene and then displaying it. According to the editor's technique, the image aesthetics of 4x3 pan &amp; scan scenes will be different. Subtitles are images obtained by inserting black bands above and below the scene and shrinking the scene, so that users can effectively view images made in wide scene specifications (16x9) in normal screens (screen ratio 4x3) . The black band above and below the image is called a flat light curtain (matte). When displayed on a 16x9 screen: Combine the 16x9 AV data into a 16x9 tag file (4) + (6) The content can be displayed in scene (2), as the content envisioned by the manufacturer, without any special operating. The third display method: The manufacturer prepares the respective AV data in consideration of the aspect ratio of the screen, and when the content with a fixed aspect ratio is produced in the following manner, the markup file relates to the screen having a different aspect ratio. When only (3), (5), and (6) are manufactured-when displayed on a 4x3 screen: 4x3 AV data is combined into a 4x3 markup file (3) + (5) content can be displayed on the scene (1), as the manufacturer envisions, no special operation is required. -When displayed on a 16x9 screen: 16x9 AV data (6) is converted to a 4x3 normal scene, 4x3 subtitle scene or 4x3 pan &amp; scan scene 10734pif doc / 008 200304646, and then embedded in a 4x3 tag file . (3) + (6) The content can be displayed by center alignment to include the right and left sides of scene (2). When only (4), (5), and (6) are manufactured-when displayed on a 4x3 screen: 4x3 AV data (5) is embedded in a 16x9 markup file (4) to include right and left blanks 'No need to expand. (4) + (5) The resolution is, for example, 854x480, so through the “hot area” and the API about aspect ratio conversion, only important screen parts can be displayed on the 4x3 screen (1). -When displayed on a 16x9 screen ... The content of (4) + (6) obtained by combining 16x9 AV data with a 16x9 markup file can be displayed in scene (2), as the manufacturer wants, without the need Perform any special operations. The fourth display method: When each AV data and mark file is manufactured in a certain aspect ratio, the AV data and mark file are related to pictures with different aspect ratios in the following manner. When only (3) and (5) are manufactured-when displayed on a 4x3 screen: 4x3 AV data is synthesized into 4x3 markup files and (3) + (5) content can be displayed in scene (1), As the manufacturer wants, no special action is required. -When displayed on a 16x9 screen: Align the center of (3) + (5) of the entire content obtained by synthesizing the 4x3 mark file through the 4x3 AV data. The displayed content of (3) + (5) may be Include the blank area on the right and left of scene (2) with 16x9 frame. When only (4) and (6) are manufactured-when displayed on a 4x3 screen: 16x9 AV data is synthesized 16x9 10734pifdoc / 008 32 200304646 and the resolution of (4) + (6) is, for example, 854x480 Therefore, only the important screen part can be displayed in the 4x3 screen (1) through the API, the hot area, and the API related to the appearance ratio conversion. In this example, it is preferred that pan &amp; scan or subtitles be applied to the video mode instead of the interactive mode. -When displayed on a 16x9 screen: The content of (4) + (5) obtained from the AV data synthesis markup file can be displayed in scene (2), as the manufacturer wants, without any special operations. Here, the “hot area” and the API related to the aspect ratio conversion will be explained in detail. When 16x9 interactive content (resolution 854x480) is displayed on a 4x3 screen (resolution 640x480), only the entire 640480 field of interactive content can be displayed on a 4x3 screen, and the remaining 214x480 area is not displayed on 4x3 Screen. Therefore, the content produced by the manufacturer includes content that must be displayed on the 640x480 area regardless of the aspect ratio of the screen at the initial layout, and includes unimportant content or any content in the remaining areas. In order to use the "hot area", the manufactured markup files are displayed on a 4x3 screen and the AV scene and the markup file scene are displayed in different ways. The interactive content uses the above features used in the object source code of the DOM API 値 viewport : "And" window: "to display, the description will be mentioned later. Bottom ’will be described with reference to FIG. 14, regardless of the aspect ratio of the screen, displaying 16x9 interactive content on a 4x3 screen. Manufacturers use the concept of "hot area" to compose markup files for display in scenes that will not be distorted regardless of the aspect ratio of the screen. That is, in the file space of the marked file shown in No. 14 10734pifdoc / 008 33 200304646, the entire marked file of 854x480 will be displayed on a 16x9 screen, and the content of the 640x480 "hot area" will be displayed on a 4x3 screen. Here, the size of the "hot area" is not fixed, but the minimum distortion size of 640x480 is taken as an example 'and its position is not fixed. In addition, in the 16x9 markup file space, the maker uses the feature 値 viewport: to select the "hot area" which is undistorted and displayed on the 4x3 screen, and uses the feature 値 window: to map to a designated area of the scene to The selected, "hot area" is displayed on a 4x3 screen. Figure 15 shows the variables of the coordinate system required in the area specified by viewport: to the area specified by window :.

The display method below uses the above display method to easily distinguish the document area, viewport area, window area, and screen 10734pif doc / 008 34 200304646 screen area and other areas using other existing display methods.

When the interactive content is initially displayed in the scene, the interactive content is displayed on the screen by using the static method of the preset style sheet in the presentation engine or the CSS defined by the links and style tags in the markup file. However, when the user input changes the aspect ratio during the reproduction process, the aspect ratio of the output screen can be dynamically changed by adding the aspect ratio conversion function to the markup file using the thread language using the DOM API. Below, a static method using the @ screen-display rule will be described. According to another embodiment of the present invention, the feature 値 screen-display type: Zenglikou to @ screen-display 贝贝 [J ° 1. screen-display type: It specifies the aspect ratio of the scenes in which the AV scenes are synthesized in the markup file. 4x3N: If the user sets the screen output to 4x3 normal type 4x3L: If the user sets the screen output to 4x3 subtitle type 4x3P: If the user sets the screen output to 4x3 pan & scan type 16x9W: If the user sets the screen output to 16x9 wide Type 2. video-placement: It specifies the display mode of the AV scene. "None", "embedded", "pip- #" and "backgroud" respectively mean nothing, embedded mode, PIP mode and background mode. Initially it was embedded mode. 3. video-viewport: It specifies the area where the required portion of the AV scene is to be increased and decreased.値 is <shape>, and the initial 値 is rect (0%, 10734pifdoc / 008 36 200304646 100%, 100%, 0%). Here, the set of <shape> is a rectangle (&lt; top &gt;, &lt; right &gt;, &lt; bottom>, &lt; left &gt;) 〇4. Background-color: This designation consists of a single color of the The background color of the AV scene.値 is &lt; color * &gt;, and the initial 値 can be changed according to the user agent. 5. window: It specifies the window in which the AV scene is synthesized into the scene of the marked file scene.値 is &lt; shape &gt;, and the initial 値 is rect (0%, 100%, 100%, 0%) ° 6. viewport: It specifies the adjustment area of the scene where the AV scene is synthesized into the scene of the mark file.値 is &lt; shaPe &gt; and the initial 値 is rect (0%, 100%, 100%, 0%).

Therefore, it is better that the manufacturer adds additional CSS to the markup file and attaches the CSS to the file. Enables users to effectively display AV data (DVD-video) and mark files with a fixed aspect ratio, even if the user sets the aspect ratio. The following display makers add CSS to mark files to make AV data (DVD) -video) and 4x3 markup files can be effectively displayed in "background mode". CSS can be formed using "style" tags, as shown in the following example, and "link" tags can be used through external reference materials. 38 10734pifdoc / 008 200304646

"Initial display aspect ratio" is a parameter obtained by initially setting the aspect ratio preferred by the user, and there are two types of 16x9 and 4x3, as shown in the above algorithm. The "no_video" parameter represents the Where the AV data (ie DVD-video) is initially loaded. If the "no_video" parameter is "0", this means that DVD-video is included in the tag file; if the "no_video" parameter is "1" , Which means that DVD-video is not included in the markup file.

Referring to FIG. 16, the above static and dynamic definitions are used, according to the screen mode (aspect ratio, resolution, and image) set by the user or set by the playback device. Output method) and display the marked file scene. The screen mode can be 44 10734pifdoc / 008 200304646 through user input and It can be changed even during the reproduction process. The viewport frame and window frame of the mark file in this example can be applied to the next mark file, if these frames have not changed. In step 1601, the display engine 3 reads The screen mode (aspect ratio, resolution, and image output method) set in the playback device or set by the user. Here, the image output method means that 16x9 images can be output in 4x3 subtitles or 4x3 pan &amp; scan, and can be used in 16x9 wide mode displayed when the scene is not distorted. When the picture is set to 4x3 size, the AV decoder 2 converts the AV stream to subtitle or pan &amp; scan type, and outputs the converted AV stream. When the picture is set When the size is 16x9, AV decoder 2 can output the AV stream to 16x9 size without conversion. This is because the AV stream is generally encoded in 16x9 size. However, it is better that the output is performed only when the AV The stream is reproduced in the video mode instead of the traditional interactive mode, and in the interactive mode, the AV stream is always output in 16x9 size. In step 1602, the preset style sheet in the display engine 3 is based on Setting the screen mode is selected, and is determined as defined in the stylesheet associated preset as viewport, window and the like of the feature video-viewport Zhi. The presentation engine 3 interprets the markup file read by the reading unit 1, and checks the style sheet linked to or embedded in the markup file. In step 1603, if the maker does not provide a style sheet in the markup document, the display engine 3 utilizes features such as viewport, window, and video-viewport defined in the preset style sheet selected according to the set screen mode. And output the markup file to the scene; if the maker provides the stylesheet in the markup file, 10734pifdoc / 008 45 200304646 the display engine 3 uses @ screen-display to use the definitions in the relevant stylesheet such as viewport, window, video-viewport, etc. Features and then output the markup file to the scene. In step 1604, it is determined whether the screen mode of the key (or key) is changed according to the aspect ratio of the user. In step 1605, if the user changes the screen mode, the display engine 3 notifies the ASPECT_RATIO_CHANGE tag file related to the aspect ratio conversion event, executes the thread caused by the event, and uses ScreenDisplayProperties in the display engine 3 to interpret the changes related to the changed Screen mode characteristics of screen mode: Variables, change the screen output status of a markup document based on the interpreted information, and output a new markup document to the scene. In step 1606, if the screen mode is not changed in step 1604, it is determined whether the output of the mark file is terminated, and the output of the mark file is terminated. In the case of tagged files, there are no modes such as subtitles or pan &amp; scan modes. Therefore, if a 16x9 size markup file is to be displayed on a 4x3 screen, the method of using "hot area" and features such as "viewport" and "window" to effectively display the markup file has been described in order to avoid the problem in accordance with the present invention. In the above-mentioned reproduction method of another embodiment, scenes with poor content seem to be distorted. Below, in the above-mentioned reproduction method according to another embodiment of the present invention, the method of most effectively synthesizing an AV scene and a markup file obtained with a fixed aspect ratio (screen ratio) without scene distortion, the user can view the closest to The display state intended by the manufacturer. At the same time, the mark file with a fixed fixed aspect ratio (screen ratio) is used to avoid repetitive recording of interactive content. The disc 10734pif doc / 008 46 200304646 space can be used more effectively. First, when a storage medium including 16x9 size AV data (DVD-vide〇) and 4x3 size mark files is displayed on a 16x9 screen through a reproduction device, the display mode (embedded mode) will be described with reference to FIG. 17 , Embedded mode and pip mode) display method. Λ First, a description will be given of a case where a 16x9AV data as shown in FIG. 17 (a) is synthesized into a markup file as shown in FIG. Π (b) under the “embedded mode ^” embedded by the “object” component. If the maker sets the "width" and "height" of the "tag" in the markup file, the 16x9AV data is represented as it is. The entire synthesized scene is selected as the viewport area, and it is not widened, so that the 16x9 screen There is no scene distortion, and the area including the right and left blank areas is selected as the window area, and the synthesized scene is displayed, so that the scene can be effectively displayed. However, if the manufacturer sets the use; ^ ,, the object is "labeled" "Width" and "Height" to embed 16x9AV data on a 4x3 screen ratio. AV data will be embedded in the markup file in normal type, subtitle or pan &amp; scan type. The synthesized scene can be displayed without expansion. On a 16x9 screen. In this example, even if the AV data is ι6χ9 size, the AV data is embedded in the 16x9 picture with a 4x3 screen ratio, so this example is not considered a better example. Secondly, the case of using the features in CSS 2 @ screen-display 値 video-placement: to synthesize AV data in a markup file in "background" mode will be described, as shown in Figure 17 (c). In the reproduction method according to another embodiment of the present invention, the view area includes AV data and mark files, but the window area is defined only in its composite scene. Therefore, if the "background" mode 10734pifdoc / 008 47 200304646 is displayed on a 16x9 screen, the AV data displayed as the background is displayed on a 4x3 screen ratio, which is the same as the aspect ratio of the marked file. Third, a case where the AV material is synthesized into a markup file in the "PIP" mode will be described using the feature _ 値 video-placement in CSS 2 @ screen-display, as shown in FIG. 17 (d). This example is similar to the embedded mode, and the original markup file will form a full 4x3 scene without considering the AV data. The markup file will be displayed in the scene. Then, the AV data below the image will be displayed in the display engine. In the transparent processing area set by each PIP- #. In this example, after the reduction in the transparent processing area, the AV data appears in each PIP- # predetermined area, so the adaptability is low.

Because the mark file is synthesized in the scene of the AV data, the area set to viewport: is mapped to window: to specify an area, so that the related interactive content can be displayed on the screen, especially, the "background" mode in various reproduction modes However, the scene cannot be reproduced as the maker imagined. That is, FIG. 18 (a) shows an example in which a 16x9AV data is synthesized into a 4x3 mark in a "background" mode in a subtitle type and displayed on a screen with a 16x9 aspect ratio. In addition, Figure 18 shows an example of 16x9AV data synthesized in the "Background" mode as a 4x3 markup file in the Pan &amp; Scan type and displayed on a screen with an i6x9 aspect ratio. Even if the manufacturer encodes the AV data into 16x9 size, because only the window area of the synthesized scene is defined when the scene is displayed, in order to avoid the AV data to be displayed in the subtitle or pan &amp; scan type, as shown in Figure 18 (a) As shown in (b), in another embodiment of the present invention, by defining only the viewport and window features of the markup file and AV 10734pifdoc / 008 48 200304646 data respectively, the viewport and window features of the data can be defined according to the aspect ratio of the screen. Compare or display mode (embedded mode, background mode and PIP mode) to display the scene in the most appropriate type. In FIG. 19, it is assumed that the mark files considering the different aspect ratios of the pictures (3) and (4) and the AV data considering the different aspect ratios of the pictures (5) and (6) (that is, the AV content of the DVD-video specification) ) The pictures (1) and (2) exist in 4x3 and 16x9. In the NTSC example, the screen resolution is 720x480 with the same number of pixels, as shown in Figure 20. Only in the 16x9 aspect ratio, the pixel width to length ratio is 1.78: 1, as shown in Figure 20 (a), and in the 4x3 aspect ratio, the pixel width to length ratio is 1.33: 1. In this way, if it is a TV picture, the aspect ratio of the scene pixels changes depending on the TV type, and it is difficult to understand the variables in the scene. Therefore, for convenience of explanation, referring to Fig. 21, a description is given of a conversion equation considering each case such as a screen ratio of 1.78x1, 1.33x1, and 1x1. That is, in all cases, there is no change in height. Conversion (1): 720x480 resolution with 16x9 pixel aspect ratio is converted to type with 1x1 unit pixel aspect ratio. Overall horizontal resolution = normalization (when the length ratio of the unit pixel is 1, the width ratio is' overall vertical resolution) = When the unit pixel length ratio is 1, the width ratio X overall vertical resolution = 1.78 * 480 = 854 10734pifdoc / 008 49 200304646 Therefore, a 720x480 resolution with a 16x9 pixel aspect ratio is consistent with a 854x480 resolution with a 1x1 unit pixel aspect ratio . That is, when converted to type (1), the following equation is formed: X (1.78: 1) = (720/854) * X (1: 1) X (1: 1) = (854/720) * X (1.78: 1) Conversion (2): Conversion between 854x480 resolution and 640x480 resolution with 1x1 unit pixel aspect ratio In the case of interactive content as 854x480 size, all content cannot be displayed on the 640x480 screen, so only relevant The 640x480 area (for "hot area") can be selected and displayed on the 640x480 screen using viewport :. When interactive content of 640x480 size is displayed on the 854x480 screen, all content is displayed in the 640x480 area, and the remaining 214x480 area is filled with the background color. That is, when the interactive content of 854x480 size is to be displayed on the 640x480 screen, the viewport of the interactive content must be fully selected; when the interactive content of 640x480 size is to be displayed on the 854x480 screen, the window area of the interactive content must be fully selected . Conversion (3): 720x480 resolution with 4x3 pixel aspect ratio is converted to type with 1x1 unit pixel aspect ratio. Overall horizontal resolution = normalization (when the length ratio of the unit pixel is 1, the width ratio, the overall vertical resolution) = When the length ratio of the unit pixel is 1, the overall vertical resolution of the width ratio X is 10734pifdoc / 008 50 200304646 = 1.33 * 480 = about 640. Therefore, the resolution of 720x480 with an aspect ratio of 4x3 pixels is consistent with the resolution of 640x480 with an aspect ratio of 1x1 pixels. degree. That is, when converted to type (1), the following equation is formed: X (1.33: 1) = (720/640) * X (1: 1) χ (1: 1) = (640/720) * χ (1 · 33: 1) Conversion (4): Conversion between 720x480 resolution with 16x9 pixel aspect ratio and 720x480 resolution with 4x3 pixel aspect ratio The following formula is formed in the horizontal resolution with 4x3 (12x9) pixel aspect ratio And horizontal resolution with 16x9 pixel aspect ratio. Χ (1 · 78: 1) = (12/16) * × (1 · 33: 1) χ (1: 1) = (16/12) * × (1.78: 1) That is, in the 4x3 picture, 720x480 resolution is most appropriate when displayed in a 16x9 screen. Therefore, when selecting an area of 540x480 in 16x9 interactive content (related to "hot area"), the selected area is correctly displayed at 4x3 Screen. However, if a 720x480 resolution with a 16x9 pixel aspect ratio is converted to a subtitle type between a 720x480 resolution with a 4x3 pixel aspect ratio, the vertical resolution will change. Therefore, the following formula is formed between the vertical resolution with an aspect ratio of 4x3 (12x9) pixels and the vertical resolution with an aspect ratio of 16x9 pixels. Υ (1.33: 1) = (9/12) * Υ (1.33: 1) Υ (1.78: 1) = (12/9) * Υ (1.33: 1) 51 10734pifdoc / 008 200304646 That is, The size of the window area in a 4x3 picture must be 720x360, so that the 720x480 resolution can be maintained at 16x9 size and displayed on a 4x3 picture. As mentioned above, when the manufacturer produces AV data and markup files according to the conversion method in the case of different unit pixel size ratios, the contents are displayed according to the screen aspect ratio, as shown in the table below. In the table below, the pixel size in each example is set to 'according to the above conversion relationship. Therefore, it is assumed that the resolution with a 4x3 aspect ratio is 640x480 and the resolution with a 16x9 aspect ratio is 854x480. In addition, in the embedded mode or the PIP mode, it is assumed that 4x3 AV data is displayed in a 200x150 area, and 16x9 AV data is not displayed in a 272xl53 area. 10734pifdoc / 008 52 200304646 4x3 mark

Iff Μ 854x480 272x153— 200304646 In the above table, (p) represents the pan &amp; scan type. According to the above table '16x9AV data, the scene of synthesizing the 4x3 tag file is displayed on the 16x9 screen as follows: In the embedded mode, as shown in (a) of FIG. 22, the 16x9AV data synthesized in the 4x3 tag file can be displayed in the embedding. In the background mode, as shown in Figure 22 (b), '16x9AV data synthesized in a 4x3 tag file can be displayed in the background mode; while in the PIP mode, as shown in Figure 22, 16x9AV data synthesized in 4x3 tag files can be displayed in PIP mode. According to yet another embodiment of the present invention, the regeneration method according to the aspect ratio can be mainly classified into: a static method using CSS and a dynamic method using an API of the DOM. When the interactive content is initially displayed in the scene, the interactive content is displayed on the screen by using the static method of the default style sheet in the display engine or the CSS defined by the links and style tags in the markup document. However, when the user input changes the aspect ratio during the reproduction process, the aspect ratio of the output screen can be dynamically changed by adding the aspect ratio conversion function to the markup file using the thread language using the DOM API. Below, the static method using the @ screen-display rule will be described. 〇 According to another embodiment of the present invention, certain features 値, such as markup files; ^ viewport and window and AV data window are defined in the improved @ screen- display gauge [j. 1 .screen-display type 4x3N: This example represents that the user sets the screen output to the normal type of 4x3, and this type is a reduced type of 16x9AV data, in which the distortion that the scene seems to become thin will not appear, unlike the traditional normal Types of. 〇734pif doc / 008 54 200304646 4x3L: If the user sets the screen output to 4x3 subtitle type 4x3P: If the user sets the screen output to 4x3 pan & scan type 16x9W: If the user sets the screen output to 16x9 wide type 2.video -placement: It specifies the display mode of the AV scene.

Here, the definition of &lt; shape &gt; is rect (&lt; top &gt;, &lt; right &gt;, &lt; bottom &gt;, &lt; left &gt;). 5. "document_viewport": It specifies the area of the window in the scene where the marked document is to be displayed on the screen.値 is &lt; shape &gt;, and the initial 値 is rect (0%, 100%, 100%, 0%). 6. video-viewport: It specifies the adjustment area of the scene where the AV scene is synthesized to the scene of the mark file.値 is &lt; shape &gt;, and the initial 値 is rect (0%, 100%, 100%, 0%) ° 7. window: its designation: It specifies the area of the window in the scene where the AV data is to be displayed on the screen. .値, and the initial 値 is rect (0%, 100%, 100%, 0). 10734pifdoc / 008 55 200304646 An example of a style sheet created using the types and features of the above @ screen-display rule is as follows. There are different types of preset style sheets depending on the display engine installed in the regeneration device, and there is no guarantee that the scene can be displayed as the manufacturer envisions. When the maker wants to display the scene as expected, CSS must be added to the markup file. The following default style sheets are the default style sheets placed in the presentation engine, and it is assumed that the AV data and markup files stored in the storage medium are 16x9 in size. The &lt; shape &gt; 2 used in the above example is based on (4) above (conversion between 720x480 resolution with 16x9 pixel aspect ratio and 720x480 resolution with 4x3 pixel aspect ratio) 10734pif doc / 008 56 200304646 © screen-display 4x3N {background ^ olor: # 000000 document-viewport: (0px ^ 629pxr479pxf90p4 document-window, (0px, 719px, 479pxy0p5〇video-viewport (0pxJ19px, 479px, 0px) video-window: (Ορχ ^ Ιθρχ ^ Τθρχ, 〇 ^ } @ scfeen-display 4x3L (background * color-# 000000 document-viewport: (0px171dpx, 479pxv0px) document-window: (60ρχ, 719ρχ, 419ρχ, 0ρ ^ video-viewport: (0ρχ, 719ρχ, 479ρχ, αρίχ) video- window: (βΟρχ, ΤΙΘρχ ^ Ιθρχ, Ορ) ^}

Fig. 23 is a flowchart showing another preferred embodiment of the reproduction method according to the present invention. Referring to Fig. 23, by using the above-mentioned static and dynamic definitions, the marked file scene is displayed according to the screen mode (aspect ratio 'resolution and image output method) set by the user or set in the reproduction device. Even during the regeneration 'screen mode can be changed by user input. The view file and window view of the mark file and AV data used in this example can be directly applied to the next mark file, if these frames have not changed. In step 2301, the display engine 3 reads the screen mode (aspect ratio, resolution, and image output method) set in the playback device or the screen mode set by the user. Here, the image output method is intended to output 16 × 9 images in 4x3 subtitles or 4x3 pan &amp; scan, and 16 × 9 wide mode, which can be displayed without scene distortion. In this example, the loading picture is set to 4 ×; 3 sizes. In the embedded mode or PIP mode, the AV decoder 2 does not output the AV stream in the subtitle or pan &amp; scan type, but outputs a 16x9 AV. Streaming is as if the screen is set to 16x9, so there is no conversion. This is because AV streams are generally encoded in a 16x9 size in a DVD playback device. In step 2302, the default style sheet in the display engine 3 is selected according to the set screen mode, and it is determined that the related default style sheets such as document viewport, document window, view〇viewport, and video window are defined in the relevant preset style sheet. The characteristics 値. 66 10734pifdoc / 008 200304646 The display engine 3 interprets the markup file read by the reading unit 1 and checks the style sheet linked to or embedded in the markup file. In step 2303, if the user does not provide a style sheet in the markup document, the presentation engine 3 uses the document viewport, document window, video viewport and video window defined in the preset style sheet selected according to the set screen mode. And other features to output the markup file to the scene; if the user provides a style sheet in the markup file, the display engine 3 uses the document viewport, document window, video according to the @ screen-display defined in the relevant style sheet. viewport, video window, etc. output the markup file to the scene. In step 2304, it is determined whether to change the screen mode of the key (or key) according to the aspect ratio of the user. In step 2305, if the user changes the screen mode, the display engine 3 notifies the aspect ratio conversion event ASPECT_RATIO_CHANGE of the relevant markup file, executes the script caused by this event, and uses the ScreendisplayProperty in the display engine 3 to interpret and supervise The screen characteristics of the changed screen mode 値, change the screen output status of the markup document based on the interpreted information, and output a new markup document to the scene. In step 2306, if the screen mode is not changed in step 2304, it is determined whether the output of the mark file is terminated 'and the output of the mark file is terminated. The above recording and reproducing method can be implemented by a computer program. The code and code sections of the computer program can be easily written by those skilled in the art. Similarly, the above program can be stored in an information storage medium, read and executed by a computer, and thus a method of recording and reproducing mark files and AV data. 10734pifdoc / 008 67 200304646 The information storage medium includes magnetic storage media, optical storage media, and carriers. As described above, according to the present invention, there is provided an information storage medium including AV data and a mark file, a recording method, a reproduction method, and more: a generating device so that the AV data and the mark file can respond to resolution and aspect ratio (screen ratio) ) And displayed in various ways in interactive mode. Therefore, the user can enjoy a good display scene. In addition, content makers and recording / reproducing device makers can take advantage of the characteristics of windows and viewports to increase / decrease markup file scenes, thus saving required memory space and providing special functions such as scrolls. In addition, some AV scenes can be increased or decreased by using the video-viewport feature. Interactive content created with a fixed screen ratio can be changed to various screen ratios using the viewport and window features of the interactive content. According to the present invention, when interactive content manufactured to a fixed screen ratio is reproduced by a reproduction device using markup language, the interactive content can be effectively displayed regardless of the screen ratio of the screen, without the need to subtract a portion of important information , Which simplifies the development process, avoids overlapping content and makes more efficient use of disc space. In addition, AV data and markup files made into a fixed aspect ratio can be effectively displayed in various formats using static methods related to aspect ratio CSS and dynamic methods using the threading language in markup files using the DOM of the API. Aspect ratio on screen. Therefore, the user can enjoy the display state closest to the intention of the manufacturer 'and the manufacturer can avoid the overlap of the interactive content and effectively use the storage medium. 68 10734pif doc / 008 200304646 Although the present invention has been disclosed above with several preferred embodiments, it is not intended to limit the present invention.
