Description

1246036 _ V. Description of the invention α) ~ .— The technical field to which the invention belongs a. The present invention relates to an information storage medium on which subtitles and downloadable fonts are used to support multiple languages, and the media Of the device. For a long time, the prior art # / Known digital versatile discs (hereinafter referred to as D V D) uses a bitmap image (b i t m a p i m a g e), which is used as a subtitle (subt / tle ^). The subtitle data of the raster image is losslessly encoded 'and recorded on a DVD that can record up to 32 subtitle data.

The following will describe the data structure of video (vide0) data on a variety of types of conventional multimedia information storage media. Figure 1 shows the data structure of a DVD. As shown in Figure 1, the disk space of a multimedia storage medium itself can be divided into a VMG area and a plurality of VTS areas. Title 2 The information on the poor news and title menu will be recorded in the VMG area, and the information on the title will be recorded in those VTS areas. VM (J zone includes 2 ~ 3 files' and each VTS zone includes 3 ~ 12 files. Figure 2 shows a detail of a v M G zone to unwind the EU.

Please refer to Figure 2. The VMG area includes a VMGI area for storing VM (extra data on J), a V0BS area for storing image information (images, files) on the menu, and a VMGI backup area (Backup area). These areas exist in the form of files, and v〇BS is not required to exist. It is the information on the title of a reproduction unit, and it is the shadow itself.

1246036 V. Description of the invention (2) The VOBS of the image data is stored in the VTS area. And one yTs to one title. Xihuiji Figure 3 shows a detailed solution of a V T S area. Please refer to Figure 3 for details. One VTS area includes video title set information (VTSI), v〇BS for menu screen image data, and one for 11 male images. V 0 BS of title group video data and one v τ s I backup data ~ V0BS showing a menu screen is not mandatory to exist; ^ every 1 second

It can be subdivided into VOBs and cells (ceUs) which are recording units. —S 嗰 V0B includes a plurality of cells. The smallest recording cell of the present invention. Figure 4 shows a detailed view of a vOBS that is itself image data. Please refer to Figure 4, a v〇BS includes a plurality of v 0Bs, and a delete B includes a plurality of cells. A cell includes a plurality of v_s. A V0M is a material encoded by a moving pictures expert (moving pictures expert = 0UP, hereinafter referred to as MPEG) method used to encode moving pictures (moving P1CtUreS) in a DVD. According to this MPEG method, because the image is encoded in the form of spatiotemporal compression (spatiotemporal c ^ pressior ^), H: image, which must be used to decode the image. Therefore, to support Γ J pairs that can reproduce data from any location Every scheduled image will be performed

Like the inner encoding of the image (called the heart-warming picture or picture of intra L). This video is also called an MPEG picture and it is 1246036 between the I picture and the next I picture. 5. Description of the invention (3) The video is also called a group of pictures (hereinafter referred to as GOP). A GOP generally includes 12 to 15 pictures. MPEG defines a system coding standard (IS0 / IEC13818-1) for encapsulating video data and audio data into a bit stream. The system coding standard defines two mul tipiing methods, including a program stream (hereinafter referred to as PS) multiplexing method suitable for generating a program and storing the private type on an information storage medium. , And a transport stream multiplexing method suitable for generating and transmitting a plurality of programs. Among these methods, the DVD uses the PS encoding method. According to the ps coding method, the image data ¥ and sound data are divided by pack (hereinafter referred to as PCK), and the time division by the pack is used to multiplex. The data defined by MPEG that is different from video data and audio data will be treated as a private stream and will be included in pcKs, so that the data can be divided with audio and video data. 'A V0BU includes multiple PCKs. The first PCK among these pcKs is a navigation pack (NV-pCK). Next, the remaining parts include video packs (V-PCK), sound packs, A-PCK, and sub picture packs (SP-PCK). The image data contained in his image package includes a plurality of GOPs. SP —PCK is used for 2-phase graphic data and subtitle data. In other words, in DV0, the subtitle data that appears to overlap the video picture is encoded using the same method as the = 2 phase pattern data. In other words, a ’does n’t use a separate encoding method that supports multiple languages, and

V. Description of the invention (4) After the subtitle data is converted into graphic data, an encoding method is used to process the graphic data and then record the data. Graphic material for subtitles, also known as a sub picture. An auxiliary picture includes an auxiliary picture unit (SPU). An auxiliary picture unit corresponds to a graphic data sheet. Figure 5 shows a correlation diagram between SPU and SP-PCK.

Please refer to Figure 5. An SPU includes an auxiliary picture unit header (SPUH), pixel data (PXD), and an SP — PCK segmentation and recording aid with multiple 2 48 bytes. The picture shows the control sequence table (SP_DCSQT). At this moment, if the last data item of the SPU is not completely filled with one SP-PCK, the remaining part of the last SP-PCK will be fully filled to keep it the same size as other SP-PCKs. Therefore, one SPU may include a plurality of SP_PCKs. SPUH will record the size of the entire SPU and the SP — DCSQT data to start recording and position. By encoding an auxiliary picture, PXD data can be obtained. The pixel data for forming an auxiliary image can have a background, pattern pixels (patte ^ n

pixel), emphasis pixel-l, and four different types of values of the emphasis pixel, which are represented by two bit values and have two bit values of 00, 01, 10, and u, respectively. Therefore, the two auxiliary pictures Y are regarded as a set of data having 4 pixel values and formed by a plurality of lines. Encoding is performed for each line. As shown in the sixth example, the 'SPU is coded by a run_length. In other words, if there are 1 to 3 predetermined pixel data items in a row, the number of consecutive pixels ^ (No_P) can be represented by 2 bits, and a 2-bit image will be recorded next

1246036

V. Description of the invention (5) Prime data value (PD). If there are 4 to 15 pixel data items in succession, the first 2 bits will be treated as 0 records, then 4 bits will be used to record Nop ', 1 and 2 bits will be used to record PD. If there are 16 to 63 pixel data items in a row, the first 4 bits will be recorded as 0, and then 8 bits will be used to record,

No —P, and PD is recorded using 2 bits. If the pixel data item continues to the end of the line, the first 14 bits will be recorded as 0, and then the PD will be recorded using 2 bits. If the encoding is not aligned in units of bytes when the first line of encoding is completed, the 4 bits will be recorded as 0. The length of the encoded data in one line cannot exceed 1 440 bits. ''

Figure 7 shows a data structure diagram of SP-DCSQT. Please refer to Figure 7, SP-DCSQT includes display control information for outputting pxd data. SP-DCSQT includes multiple auxiliary picture display control sequences (SP-DCSQ). An SP-DCSQT is a set of display control stamps (SP-DCCMD) that are executed once and includes an SP-DCSQ-STM that indicates a start time, and an SP-NXT that contains the next SP-DCSQ location information. DCSQ —SA and a plurality of SP—DCCMD. SP-DCCMD is a control information used to control how pixel data (pXD) and image pictures are combined and output, and includes pixel data color information, image data comparison information, and output time and end time information.

Fig. 8 shows the intention of taking into account the output situation of the auxiliary picture data. Please refer to Figure 8. The pixel data itself will be encoded into PXD without damage. SP — DCSQT contains information on an SP display area, where the gp display area is an auxiliary where the auxiliary picture is displayed in an image display area

1246036 V. Description of the invention (6) The picture display area, and the information about the minimum interval and the end time of all the ψ in-. The auxiliary pictures and materials of the materials; the work in the same language as the subtitles in different languages is to do multiple jobs and record.

V. Description of the Invention (18) Figure 11 shows the textual material Bi as a subtitle / preferred embodiment according to the present invention. Please refer to FIG. 11. In this embodiment, a markup language is used as text data of a subtitle. Considered as the purpose of the sub-curtain 'This embodiment uses the minimum number of tags or elements as subtitles in the markup language, and as described above, it may include tags or elements for synchronization and daytime display. Attributes (aUribuks). The subtit le, head, meta, body, and p elements are shown as examples. In this embodiment, the information is displayed in an attribute manner. The attributes used in this example are described below. -start: indicates the time when the start time of the reproduced animation should be set to 0, and the sub-screen data corresponding to the animation should be output. Subtitle display time is represented by hours (HU): minutes (mm): seconds (SS): frame (FF). This time can be expressed in thousandths of a second. In addition, if the image data is a kind of evaluation image, the time may have a presentation time stamp (hereinafter referred to as pts) of the image frame superimposed and displaying subtitles. In general, the PTS value is a count that operates at 27 MHz or 90 KHz. If a PTS value is used, the subtitle data can accurately match the image data and work with it. / end (end time): Represents the time when a caption appears, and the time has the same type of attribute value as " s t a r t ". -position (position): used to represent the coordinates of the vertex of the upper left corner of an image area in the display area where the subtitle data is displayed.

1246036 V. Description of the invention (19)-direction: It is used to represent the direction in which the subtitle data is displayed. -size: used to represent the width or height of the display area where subtitle data will be displayed. If the " direction " attribute value is " horizontal (horizontal) ', it represents a fixed width value of a subtitle box. If the 'direct ion " attribute value is " vertical ", it represents a fixed height value for a caption box.

Among the various components used, the subtitle component is used to indicate the root of the text data, and the head component is used to include a meta component required to process all document data, or it is not shown in the example in Figure 11 A sty le element shown. In this embodiment, the meta element is used to represent the title corresponding to the text data and the language to be used. In other words, when multiple languages are selected, the desired language file can be easily selected by using the 1 ^^ 3 information 'in the text data. In addition, if a different directory has been prepared for each language text file, you can distinguish the different languages by the name of the text. v

Therefore, before reproducing the image data, the stored subtitle data will be = the buffer of the reproduction device, and by reproducing the image data, the subtitle data can be converted into graphic data by the green box and overlapped with =. Therefore, the subtitle data is displayed at a precise point in time. As mentioned above, for text data, in addition to subtitle data, control information should also be written in a pre-defined format. 弋 ^ ^ 予 & ▲ Item 疋 format or syntax.

1246036 V. Description of the invention (20) Negative material and decoder & plus one channel (chal = \ image picture synchronization) This embodiment sets the regeneration time and decoding. This channel can be used to transfer blocks and exchange information with each other. Regeneration status The information of the decoder can be compared with the text in the first square of the text of the decoder. Figure 2 shows a data structure diagram of the text used in a language different from the language of Figure 11. π Figure I2. The text data is recorded in ΠϊίΙ. By encoding the video data and subtitle data separately, you can easily add text data in different individual languages to the compilation m: material, and you can complete support for multiple countries. Language function. This ^ ^^ shell material is not stored with the image data in the information storage media. The type of data 'is downloaded via the Internet, or loaded from the -extra information storage' to the playback device. Easily fund subtitles in his example. F — ^ When supporting multiple languages, a subcode for the text must be determined. The preferred embodiment of the present invention is to use Unicode QUnicode is available To represent the world Multilingual character horses with more than 65,000 characters. According to Unicode, the mother character is represented by a code point (code P〇int) of ic. The character used to represent an individual language has the rules Code point group. It has a space of continuous code point characters, also known as a code chart. In addition, Unicode also supports UTF-8, UH6, and UTF-32, as a code that actually stores or transmits character data. These are code points. These formats use multiple data items of 8-bit length, 1 β-bit length, and 32-bit length, respectively.

1246036 V. Description of Invention (21) Character. The ASCIi code used to represent English characters and the IS08859-1 code used to represent European national languages represented by extended Latin have code point values from 0x0 0 to OxFF in the Unicode code. Japanese hiragana characters have code point values from 0 = 3 0 4 0 to 0 3 0 9 F. The 丨, 7 2 characters used to represent modern Chinese have a code point value from (^ 八 (: 〇〇 to (^ 1) 7 讦). Where χ represents a code point value represented by a hexadecimal number.

If the subtitle data contains only English characters, UTF-8 encoding is preferred. For Korean or Japanese subtitle data, if UTF-8 is used, 3 bytes can be used to represent a character. If you use Dingbu 18, you can use 2 7G groups to represent one character, but each English character included in the subtitle data at the moment can also be represented by 2 bytes. Each country has its own Unicode character code. For example, in the ^ Korean ^ symbol code group KSC561H, Korean characters have 2-byte code points, and Feizim has 1-byte code point values. If the subtitle data is generated by using Unlcode and using the character groups of each country, the mother-reproduction device must know all the character groups and the complexity. There are sub-symbols, and therefore it will increase its realization to treat subtitle data as text data. In addition, in order to support multi-languages, there are two types of fonts: two: fonts. It was very difficult for Mu Cheng, a native of Tucheng, to support many countries when asked. Therefore, in the present invention, the font data of the characters that are only used for = is used as the word storage information in the Bessun storage medium, so that in the reproduction of the image data < ^^ on the information storage medium, The subtype data can be loaded into the

In other words, ^ 下 炎 i #Each part of the text data is linked to the font data, and 1 3 ^ ~ data. The subtitle text data and font data are linked to the subtitle text data, or recorded in-"; for example, in; students: f users perform language changes during data reproduction * ^ ^ ^. 刖, the playback device will load the image data and the second scene data and font data, and the next use of this image and the stand-alone L 2 playback means that the fixed number of output of the image data will not be interrupted. Regeneration of secondary materials. Generally speaking, the reproduction device will store a pre-recorded number of _ shells in a video and sound buffer to reproduce data, and if the buffer of the reproduction device can be prevented from underflowing ( ~ Underflow), continuous playback can be performed. When the playback is changed during the playback, the subtitles or font data corresponding to the image data are read again through the reader box, if the The video disk audio signal underflow does not need to be loaded in advance. Figure 13 shows an example of a text file used in the present invention. Please refer to Figure 13 for illustration. In this embodiment, Use a css file format ' As an application that implements the style in the markup language of text files, a sty 1 e component is used in the head component. By using CSS, subtitle data can use various fonts of different sizes and colors. Some users may feel that It is not convenient to set the subtitle style to a predetermined value. For example, if the font size of the subtitle file is quite small, users with poor eyesight may feel inconvenient. Therefore, when it uses ^ a same text file, how to Use and display styles with full ^

1246036

V. Description of the invention (23) The user or the user with poor eyesight has become one of many important issues. Therefore, there is a menu that allows the user to determine the font size. When a media J is reproduced in a first-reproducing device, one operation can be set according to the user, and there are a plurality of available for use. A style sheet for multiple styles of the selected option. The following will describe a @user rule according to the present invention, in which a user can set a subtitle style. The consumer type is a set of CSS properties. In this embodiment, the detailed distinction of the types of users, that is, the degree of poor vision is not important '. Therefore, only two examples will be described below.

-smal 1: The style for normal vision users-large: The style for users with poor vision is shown in Figure 14, which can be displayed by using a @user rule, or using different styles for good vision Pre-set captions in various styles for visually or visually impaired users. The difference is that the playback device can also be based on the individual preferences of the user, without the preset position and size of the subtitle data, and the output can be applied to subtitles of different positions and sizes. —Figure 15 shows an example of the text data as subtitles implemented in Figure 1 and displayed on the actual screen.

Please refer to Figure 15. Because the second < p > component is shown in the picture, the width value of the subtitle data display area will be determined by the attribute " size, which is fixed at 52. Subtitle data that cannot be represented within one line will be displayed after the change = one click. In still another embodiment, the subtitle data can be rotated only in the display area, and a line change element (br) can be used to force the line change

1246036 V. Description of the invention (24) The use of "directi ο η" is a ten-year period when subtitles in a predetermined language are being reproduced. The third < ρ > element is an example of displaying subtitle data all the time. Figure 16 For an example of a user performing a language change, please refer to Figure 16. When the language needs to be changed, the reproduction subtitle f will change the subtitle text data to be reproduced. Draw and change the language data, and the subtitles created by these actions. If the subtitle data and font data are all built with 3 word punchers, you can easily perform continuous reproduction of image data. Text data or font data is not loaded into the buffer, then j ^, dynamic data is loaded into the buffer. At this moment, the items that will interrupt the image data will first be able to execute multiple kings without interrupting the image reproduction. The size of the screen data and font data, the library "quote," as the font size. In this example, the supported languages are smaller than the individual buffers, by creating a language limit Therefore, this problem is presented here. The unit of σ set can solve the problem. Figure 17 shows an example of multiple language sets for multiple languages. Curtain—Paper material and font information. Please refer to Figure 17 The subtitle data and font data of _ Yingyan will be added to the subtitle data of multiple languages in one language set. ^ ^ Two into multiple language sets. Corresponding to the size of the punch. The user's selection of 丄 will be limited to the subtitle data of a language that must be less than the slow setting value. === The buffer selection is used as the pre_.

Description of the invention (25) Don't be loaded into the buffer first, and start to reproduce the image data. When performing language change using f, because the data is already loaded into the buffer, the subtitle data included in the language set can be executed Language changes. However, if a language change is requested that is not included in the language set, the playback device will reload the subtitle data and font data for the desired language set. In this example, 'the All the current language set data is deleted. At this moment, interruption may occur during the reproduction of the video data. Next, if a language change is to be performed, the relationship between the language and the language set to be loaded into the buffer will be based on , Execute the change language action again ^ The language set information can be recorded on the information storage medium, or it can be stored in the information storage medium considering the size of the data and the buffer size of the reproduction device. When the data is reproduced, the reproduction device can decide this choice. ^ The following will refer to a preferred embodiment to explain in detail the relationship between the information required to reproduce the image data and the subtitle data information. "Clip" will be used as a name representing a recording unit of the image data 'While PlayList and Playltem are used to represent the reproduction unit 0, in the information storage medium according to the present invention, the AV stream is divided and recorded in segments. Generally, a clip is recorded in a continuous space. Will reduce its occupied capacity, the AV bit stream will be compressed before recording. Therefore, to reproduce compressed AV streams, it is necessary to first obtain the attribute information of the compressed video data. Therefore, clip information is recorded in each clip. Clip information contains the audio and video attributes of the clip, and a random access to an entry point (Entry point) location information recorded in each predetermined interval.

1246036 V. Description of the invention (26) Entry Point Map. In MPEG, which is widely used as an image compression technology, 'the entry point is where the I picture of an in ^ ra image is compressed' and the entry point mapping table is mainly used to find Time search at a point in time within a predetermined time interval.

PlayList is a basic unit for regeneration. And an information storage medium will store multiple PlayLists. A PlayList includes a series of Playltems. PlayItem corresponds to a part of a clip, and more specifically, the Play Item is used in the example where the playback start time and end time of a clip are set. Therefore, by using the segment information, the position of the part in an actual segment corresponding to the P1 ay Item can be confirmed. Fig. 18 shows a schematic diagram for explaining piayLis1 :, piayItein, slice information, and a slice correlation.

The font information is marked in Figure i 8. In general, subtitles are preferred and are not generated for the language. Because of &, font data can be recorded in one pair for each type. Figure 19 shows one according to the present invention. Please refer to Figure 19, in a directory, the fragment structure playList, subtitle text data, and font information, γ: and according to its different types, recorded in different directories are empty, prefer text files as subtitles A separate directory space from the font file Xingding God property and video materials. / 、 Ziyi files can be stored in the information storage dragon invented by / ΛΤΛΛ, which is a kind of removable information storage medium without fixing. Unlike the old storage and use of hard disks, 'removable information storage media has a limited record: Amount ::' Regeneration device, which usually has limited capacity] As a font asset for subtitle data #, will: two Only the subtitle data and the material data on the body—㉟, are reproduced on the removable information storage medium to reproduce the image data from the information storage medium. And when reducing the amount of data that needs to be prepared in advance. , Xiong and Jingyou use this information, a representative example of Ke. The disc is that the removable recording media image data is stored in a separate benzine storage medium according to the subtitle text data of this issue, and is used for multiple languages, and the subtitle text data is used for rotation. The font information of the subtitle data is 1246036. V. Description of the invention (28) ___, the reproduction device will only include the subtitle data and the font, and then when the image data is reproduced, the base is loaded into the buffer surface and overlapped. And output the subtitle information. Yubei and Image Day Figure 20 shows an example to illustrate the dream of regeneration. 、 Rotating subtitle data Please refer to Figure 20, the playback device may have the function of subtitle data. In other words, according to a variety of special features, only rotations will be made: there will be no regenerating image data, and only the subtitle data that is about to be included in it will be converted into graphics and the next round of materials will be overlapped. Foreign language =. 1 ^ In this example, the data does not overlap, and only subtitle data is output. In addition, both position information will be ignored, and the playback device will output two line data items including subtitle data on the entire day, and will wait for a user input. After viewing all the output subtitle data, the user will send a signal to display the next line of subtitle data to control the output time of the subtitle data. Fig. 21 shows an example for explaining that the reproduction device outputs subtitle data in more than one language at the same time. Referring to FIG. 21, according to a preferred embodiment of the present invention, when subtitle data includes a plurality of languages, the reproduction device may have a function of outputting subtitle data in two or more languages simultaneously. At this moment, by using the synchronized information of the subtitle data of each language, the subtitle data displayed on the screen can be selected. In other words, the subtitle data is output in the order of the output start time, and when the output start time is the same, the subtitle data is output according to the language.
