具体实施方式 Detailed ways

现在通过参照附图将更加详细地描述使用有关图形数据压缩的元语言的一种丰俞入文件生成系统。 Referring now to the drawings in greater detail by the description of the use of a data compression related graphical element into the language of the document generation system is Yu abundance.

对于编辑者来说需要一种能够调整编辑、表示、处理以及压缩三维(3D ) 内容所必须的要素的方法,以便能够很容易地处理被压缩的3D数据。 For a need for an editor for editing can be adjusted, said compression element and the process a three-dimensional (3D) content necessary for the method to be able to easily handle the compressed 3D data. 可以通过使用XMT来调整上述要素。 These elements can be adjusted by using the XMT. XMT是用于编辑诸如音频、视频、两维(2D )内容以及三维(3D )内容之类的MPEG-4内容的框架(framework )。 XMT is a framework for editing, such as audio, video, MPEG-4 content of the two-dimensional (2D) and three-dimensional content (3D) content or the like (framework). 同样,XMT是一个使用文本语法表示MPEG-4情景描述的框架。 Similarly, XMT Syntax Notation is a text frame using the MPEG-4 scene description. 该框架将在图3中进行说明。 The framework will be described in FIG. XMT允许内容编辑者、工具(tools)以及服务提供者再使用由另一内容编辑者所制作的内容,并且还能够使其与可扩展3D (X3D)和同步多媒体集成语言(SMIL)共同使用。 XMT allows content editors, tools (tools) and service providers re-use content editor by another content produced, and also enable it to be used with Extensible 3D (X3D) and Synchronized Multimedia Integration Language (SMIL).

如图3所示,XMT格式能够在SMIL播放器、虚拟现实建模语言(VRML)播放器和MPEG-4播放器之间互换,并且通过这些播放器播放。 As shown, the XMT format can be played in the SMIL 3, Virtual Reality Modeling Language (the VRML) interchange between the player and an MPEG-4 player, and the player played through. 更准确地说,参考图3,在预处理X3D内容之后,可以通过SMIL播放器来分析和播放XMT格式,或通过VRML播放器播放XMT格式,或在编译MPEG-4 ( mp4 )格式的表示之后由MPEG-4播放器来播放XMT格式。 More specifically, with reference to FIG. 3, after the pretreatment X3D content can be analyzed by the SMIL player and player XMT format, or by a VRML player to play XMT format or represents (MP4) format, MPEG-4 compiled after by the MPEG-4 player to play XMT format.

在XMT-A格式和XMT-Q的双结构中给出XMT格式。 XMT format is given in the XMT-A format and a double structure of XMT-Q. XMT-A格式是一种MPEG-4内容的基于XML的版本(version),并且包括可扩展的3D图形(X3D),所述MPEG-4内容表示音频、视频、2D或3D图形数据,或它们的压缩。 XMT-A format is XML-based version (Version), and comprising a scalable 3D graphics (X3D), the MPEG-4 content represent audio, video, 2D, or 3D graphics data, MPEG-4, or one kind of content compression. XMT-A格式还包括作为XMT-A格式的扩展的X3D,以表示MPEG-4 的特征。 XMT-A format further comprises an extended as XMT-A format X3D, to represent the characteristics of MPEG-4. 在XMT-A格式中,文本格式和二进制格式以l: l的比率映射。 In the XMT-A format, a text format and binary format l: l ratio map.

XMT-Q格式是基于SMIL的MPEG-4特征的高级表示。 XMT-Q format is based on MPEG-4 advanced showing features of SMIL. 即使内容的编辑者不熟悉从Q到A的机制,XMT也能够从XMT-Q格式默认地映射为XMT-A 格式。 Even if the contents are not familiar with the mechanism of the editor from Q to A, XMT default can be mapped from the XMT-Q format XMT-A format. XMT-Q格式提供一种能够使用户方便地编辑内容的界面提示功能。 XMT-Q format to provide an enabling users to easily edit the content interface prompts. 通常,MPEG-4数据以XMT-A格式表示、处理和压缩。 Typically, MPEG-4 data are expressed XMT-A format, processing and compression.

因此, 一种调整编辑、表示、处理和压缩3D数据所必须的要素的压缩技术必须在XMT-A格式中定义,以便对于编辑者来说能够去压缩3D数据。 Hence, an adjustment of editing, said data processing and compression 3D compression necessary elements must be defined in the XMT-A format in order to be able to compress 3D data for editing are concerned.

换句话说,因为在XMT格式中定义由MPEG-4 AFX所建议的压缩数据的表示,因此可能压缩与编辑者制作的3D内容相关的动画数据和表示数据。 In other words, because the definition of the data represented by the compressed MPEG-4 AFX suggested in the XMT format, so the compression may be related to production of 3D content editor and animation data representing data. 从而,编辑者能够基于该定义压缩3D数据,并且发送所压缩的数据。 Thus, the editor can be compressed 3D data based on this definition, and transmits the compressed data. 也就是说,压缩诸如动画数据和表示数据之类的3D数据所需要的要素与参数一起在XMT格式中定义。 That is, parameters such as the compression element and the animation data and the data representing the 3D data or the like required in the XMT format defined together. 根据本发明,通过使用表示3D数据的压缩的节点, 在XMT-A模式中定义用于3D数据压缩的要素定义。 According to the present invention, by using the 3D data of a compression node, the XMT-A defined in the schema defines an element for 3D data compression.

在本发明中,提供一种使用元语言表示3D数据压缩的要素的方法并且基于上述方法压缩3D数据。 In the present invention, there is provided a method of using a meta language elements represent 3D data compression and compression of 3D data based on the method described above.

图2的系统包括XMT分析器210、 XMT2MUX样式表220、 XMT2BIFS样式表230和XMT模式240 。 XMT system of Figure 2 comprises an analyzer 210, XMT2MUX stylesheet 220, XMT2BIFS style sheets 230 and 240 XMT mode. XMT模式240定义包含有关被压缩的对象数据的信息的压缩节点,数据压缩参数,以及包含有指定压缩对象数据的位置的信息的BitWrapperEncondingHints。 240 XMT pattern definition contains information about the object data is compressed compressed node, the data compression parameters, and BitWrapperEncondingHints contains information specifying the location of data to be compressed.

压缩节点与包含将被压缩的对象数据的节点字段、緩冲字段和URL字段不兼容,緩沖字段与统一资源定位器字段不兼容并且使用带内场景(in-band scenario )传输在节点中所定义的比特流,以及URL字段与緩冲字段不兼容并且使用带外场景(out-band scenario)传输包含在节点中的压缩比特流。 Compression node and the node field contains the compressed object data, and the URL field buffers field are not compatible, and field buffer field is not a uniform resource locator-compatible and uses a scene (in-band scenario) defined in the inner band transmission node bitstream, and the URL field is not compatible with the buffer and the field-of-band scenario (out-band scenario) transmission including compressed bit stream in the node. 数据压缩参数可以至少包括下列参数之一:用于有关于对象的顶点坐标的基于关键帧(keyframe-based)的动画数据的参数,用于对象的旋转信息的参数,用于被压缩对象的位置信息的参数以及用于被压缩的3D网格信息的参数。 Data compression parameters may include at least one of the following parameters: parameters for animation data regarding vertex coordinates of the object based on a key frame (keyframe-based), the parameters for the object rotation information, a position of the object to be compressed parameters and parameter information for 3D mesh information to be compressed.

现在将更加详细地描述图2的系统。 System of Figure 2 will now be described in more detail. 首先,描述包含有将被压缩的3D数据的压缩节点,和使用有关压缩节点的参数的XMT-A的数据压缩方法。 First, the compressed data comprising the compressed 3D node data, and parameters related to the use of compressed node XMT-A compression method.

由于缺少有关3D数据压缩的XMT-A模式的定义,因此现有的XMT技术不能分析有关3D数据压缩的输入XMT文件。 Due to the lack of definition of the 3D compression data XMT-A mode, and therefore the prior art can not analyze the XMT input XMT file relevant 3D data compression. 可是,根据本发明,如图2所示, XMT-A模式240包含了有关3D数据压缩的压缩节点和相关参数的定义。 However, according to the present invention, shown in Figure 2, XMT-A 240 contains the pattern definition 3D compression data compression node and related parameters. 所以,XMT分析器能够基于XMT-A模式240中的定义、XMT2MUX样式表220 和XMT2BIFS样式表230,来分析通过使用压缩节点而定义3D数据压缩的输入XMT文件200,并且产生输入到MPEG-4编码器的文件。 Therefore, the analyzer can be based on the XMT XMT-A defined pattern 240, XMT2MUX XMT2BIFS stylesheet 220 and style sheet 230, analyzed by using the compression node defines the 3D data compressed input XMT file 200, and generates inputs to the MPEG-4 file encoder. MPEG-4编码器包括BIFS编码器250和MP4编码器260。 MPEG-4 BIFS encoder comprises an encoder 250 and MP4 encoder 260. 当所产生的文件输入到BIFS编码器250 和MP4编码器260时,产生.mp4比特流,由MPEG-4播放器(未示出)可视化并且显示在显示器上。 When the file generated is input to the BIFS encoder 250 and the MP4 encoder 260, a bit stream generating .mp4, (not shown) visualized by the MPEG-4 player and displayed on the display.

当使用压缩节点和有关3D数据的基于元语言的参数时,也就是使用定义3D压缩节点和参数的XMT-A模式,编辑者能够判定在编辑处理期间,3D 数据是否将被压缩。 When using the compression node and parameters related to the 3D data based on the meta-language, which is defined using the 3D compression XMT-A schema node and parameters, the editor can be determined during the editing process, whether 3D data is to be compressed. 如果判定3D数据将被压缩,则必须使用元语言给出参数。 If it is determined 3D data will be compressed using a meta language must be given parameter.

如果编辑者判定需要压缩3D数据,则在调整参数的同时,通过使用随后两种方法之一来传输3D数据,所述两种方法为(i)将3D数据压缩为比特流并且传输该比特流;以及(ii)使用已压缩比特流来传输3D数据。 If the editor determines that need to compress 3D data, while adjusting the parameters, the 3D data is transmitted by using one of two methods Subsequently, the two methods (i) the 3D data into the bit stream and transmitting the bitstream ; and (ii) using the compressed bit stream to transmit 3D data.

上述两种方法可以细分为四种方法:(i)使用参数将原始数据压缩为比特流并且使用緩冲器传输比特流;(ii)通过緩冲器使用已压缩比特流来传输原始数据;(iii)使用参数将原始数据压缩为比特流并且使用URL传输比特流;以及(iv)使用URL传输已压缩的比特流。 The above four methods can be subdivided into two methods: (i) using the parameter data into the original bit stream and the transmission bit stream using a buffer; (ii) by using the compressed bit stream buffer to transmit the original data; (iii) using the parameter data into the original bit stream and the transmission bit stream using the URL; and (iv) using the URL transmitted compressed bit stream. 编辑者可以使用上述四种方法之一来传输3D数据。 Editors 3D data may be transmitted using one of four methods described above.

接下来,将描述一种在XMT格式中使用元语言表示用于压缩3D数据的因素的方法。 Next a metalanguage in the XMT format using the factor representing a method for compressing 3D data will be described. 在该方法中,通过使用元语言表示有关3D数据压缩的压缩节点和参数。 In this method, by using a meta language of a compression node and parameters relevant 3D data compression. 在该发明中,将通过3D数据压缩所需要的"BitWrapper"节点和参^t来描述该方法。 In this invention, compressed "BitWrapper" node and parameters required ^ t the method is described by 3D data.

简言之,"BitWrapper"节点定义从包含在节点字段中的数据到比特流的压缩和使用带内场景或带外场景对比特流的传输。 Briefly, "BitWrapper" node definitions belt provided with compression and transmission of a scene or band bitstream scenes contained in the data stream from the node into a bit field. "URL"字段将数据的传输定义为带外比特流,以及"buffer"字段将数据的传输定义为诸如BIFS比特流带内比特流。 "URL" field defines transmission of the data for band bitstream, and the "buffer" field defines transmission of the data bit stream within a bit stream such as a tape BIFS.

如果编辑者压缩并且传输在"BitWrapper"节点中所定义的数据,那么程 If the editor compressing and transmitting data "BitWrapper" node is defined, then the process

序设计者必须调整用于产生比特流的参数。 The designer must be adjusted for generating sequence parameter bit stream. 可以使用XMT-A模式语法来进行参数的调整。 XMT-A may be used to adjust model parameters syntax. 然而,由于参数除了与特殊的编码语法相关外还与"^码语法相关,因此在数据压缩期间可以调整参数。"BitWrapper"节点通过使用七种压缩工具而支持被压缩比特流的传输。 However, since in addition to the parameters associated with a particular coding syntax with further "^ associated code syntax, it is possible to adjust the parameters during the data compression." BitWrapper "node by using seven compression tool support transmission of the compressed bit stream.

4.2语义 4.2 semantics

在原始的"ObjectDescriptorUpdate"语法中,"Update OD"不含有描述。 In the original "ObjectDescriptorUpdate" grammar, "Update OD" does not contain a description. 在修改过的"ObjectDescriptorUpdate"语法中,当编辑者将一个场景描述流(BIFS流)经由"URL"字段链接到另一个元素流时,可以使用"Update OD"。 In the modified "ObjectDescriptorUpdate" syntax, the editor when a scene description stream (the BIFS stream) via link "URL" field to another elementary stream, may be used "Update OD". 同样,ObjectDescriptorID和脚本文件(script file)加到"Update OD"。 Similarly, ObjectDescriptorID and script files (script file) added to the "Update OD". "ObjectDescriptorUpdate"语法的格式与二进制文本格式的格式相同。 "ObjectDescriptorUpdate" the same format as binary text format syntax.

在下文中,将描述根据本发明,使用有关图形数据压缩的元语言的输入文件生成方法和系统。 Hereinafter, the present invention will be described, using a meta language-dependent graphics data compressed input file generation method and system.

首先,参考图2和4来描述根据本发明的优选实施例,使用编码参数将原始数据压缩为比特流和使用緩沖器传输比特流的方法。 First, referring to FIGS. 2 and 4 will be described according to a preferred embodiment of the present invention, the coding parameters to the raw data compression method using a bit stream buffer and the transmission bit stream.

图4说明以下情况:使用参数,将有关诸如杯子(cup)这样的对象A的3D数据,例如几何结构信息、连接信息和颜色信息压缩成比特流,并且使用緩沖器将比特流传输到"BufferWithEP.m3d"。 FIG 4 the following description: Using parameters, such as the relevant cup (cup) 3D data thus an object A such as geometry information, connection information, and color information is compressed into a bit stream using the bit stream to the buffer "BufferWithEP .m3d ". 如图2所示,当输入XMT文件输入到XMT分析器210时,XMT分析器210基于XMT-A模式,使用XMT2BIFS和XMT2MEX样式表将与场景数据一起的比特流插入到的". scene"文件中,并且将".scene"文件传输到BIFS编码器。 As shown, when the input XMT file input to the XMT parser 210 when, based on the XMT parser 210 XMT-A mode, and XMT2MEX XMT2BIFS stylesheet scene with inserted data bit stream to ". Scene" File 2 , and transmits ".scene" file to the BIFS encoder. 在该情况中,".mux" 文件包舍有一个对操作BIFS编码器的结果进行描述的".bifs/. od"文件,该BIFS编码器是MPEG-4编码器。 In this case, ". Mux" package has a rounded result of the operation will be described in the BIFS encoder of ".bifs /. Od" file, the BIFS encoder is MPEG-4 encoder. 同样,当包含在".mux"流中的信息和".bif/. od"文件输入到MP4编码器时,产生".mp4"文件。 Similarly, when it is contained in the ".mux" information stream and ".bif /. Od" when the file is input to the MP4 encoder generates ".mp4" file. 使用MPEG-4播放器可以再现".mp4"文件(有关细节参见随后的实施例l )。 Using MPEG-4 player may reproduce ".mp4" file (for details see subsequent examples l). [实施例l] [Example L]

XMT文件的例子如下,其中该文件定义通过使用"BitWrapper"节点和参数而将有关原始数据的3D网格信息压缩成比特流,并且通过使用緩沖器来传输比特流: Examples of XMT file is as follows, wherein the file is defined by using the "BitWrapper" node and parameters related to the 3D mesh information of the original data into a compressed bitstream, and the bitstream is transmitted by using a buffer:

如果XMT分析器210接收到实施例1中的XMT文件,其中所述XMT文件使用"BitWrapper"节点和参数定义压缩的3D网格信息的表示,那么XMT分析器210使用在"BitWrapper"节点中定义的3D网格信息的压缩参数压缩XMT文件并且产生比特流。 If the XMT parser 210 receives the XMT file in Example 1, wherein the XMT file representing "BitWrapper" node and parameters define the compression 3D mesh information, the XMT parser 210 used in the definition of "BitWrapper" node 3D mesh information compression parameters XMT file and generates a compressed bit stream. XMT文件的压缩和比特流的产生基于定义"BitWrapper" 节点和参数的XMT-A模式。 XMT file and the compressed bit pattern generated based on the definition XMT-A "BitWrapper" node and the parameters of the flow. 同样,使用"XMT2BIFS"和"XMT2MUX"样式表来产生XMT-A模式,和输入到MPEG-4编码器的".scene"及".mux"文件。 Also, use of "XMT2BIFS" and "XMT2MUX" stylesheet to generate the XMT-A mode, and is input to the MPEG-4 encoder ".scene" and ".mux" file. 结果,获得随后的文件: As a result, the following documents:

将上述的".scene"和".mux"文件输入到MPEG-4播放器并且通过BIFS编码器250产生".bifs/. od"文件。 The above-described ".scene" and ".mux" files input to the MPEG-4 player and generates ".bifs /. Od" BIFS encoder 250 files. 然后,将".bifs/od"文件和".mux"文件输入到MP4编码器260,从而产生".mp4"比特流。 Then, the ".bifs / od" file and the ".mux" files input to the MP4 encoder 260, thereby generating ".mp4" bitstream. 最后,在MPEG-4播放器的屏幕上可视化".mp4"文件。 Finally, in the MPEG-4 player's screen visualization ".mp4" file.

第二,参考图2和5来描述,通过使用一个緩冲器来传输使用了已压缩比特流的原始数据的方法。 Second, with reference to FIGS. 2 and 5 will be described, it is transmitted by using a buffer method using the original data compressed bitstream. 参考图5 ,与使用有关在输入XMT文件中所指定的"BitWrapper"节点中定义的对象A的参数和3D数据将原始数据压缩成比特流并使用緩沖器来传输比特流的第一种情况相比,将有关诸如一个杯子的对象A的3D数据,例如几何结构信息、连接信息和颜色信息已经压缩成比特流,并且经緩冲器将比特流传输到"BufferWithEP. m3d"。 Referring to FIG 5 the first case, the use of parameters and 3D data about the definition of the input XMT file specified in the "BitWrapper" node in the original data of the object A compressed into a bitstream and transmitted bit stream using a buffer with ratio, data relating to the 3D object a such as a cup, for example, geometry information, connection information, and color information has been compressed into a bit stream and the bit stream transmitted by the buffer to "BufferWithEP. m3d".

如图2所示, 一接收到XMT文件200, XMT分析器210基于XMT-A模式240,使用XMT2MUX和XMT2BIFS样式表220和230,将已压缩的比特流和场景数据一起插入到".scene"比特流,并且传输".scene"比特流。 2, upon receiving the XMT file 200 is, based on the XMT parser 210 240 XMT-A mode, and the use XMT2MUX XMT2BIFS stylesheets 220 and 230, together with the compressed bit stream data into scenes and ".scene" bit stream, and transmits ".scene" bitstream. 在该情况中,".mux"文件包含了一个通过BIFS编码器250也就是MPEG-4编码器所产生的".bits/.od"文件。 In this case, ". Mux" 250 is a file containing the MPEG-4 BIFS encoder by an encoder generated ".bits / .od" file. 还,将".mux"和".bifs/. od"文件输入到MP4编码器260 中,从而通过MPEG-4播放器产生和显现一个最终的".mp4"文件。 Also, the ".mux" and ".bifs /. Od" MP4 file input to the encoder 260, and appears to produce a final ".mp4" files MPEG-4 player. 在实施例2中已经公开了通过一个緩沖器来传输使用已压缩的比特流的原始数据的方法的一个实例。 In one example of the method disclosed in Example 2 has been transmitted using a compressed bit stream through a buffer of the original data.

如实施例2所公开的, 一接收到XMT文件,XMT分析器210就产生将使用在"BitWrapper"节点中定义的緩沖器传输的比特流,其中XMT文件定义使用在"BitWrapper"节点定义的緩冲器传输代表3D网格信息的已压缩比特流, 该比特流表示被压缩的3D网格信息。 As disclosed in Example 2, upon receiving the XMT file, the XMT parser 210 generates a transmission buffer used in the definition of "BitWrapper" node in the bitstream, wherein the XMT file is defined in "BitWrapper" node definition buffer Representative red transmitting compressed 3D mesh information bit stream, the bit stream representing the compressed 3D mesh information. 该比特流是依据定义"BitWrapper"节点和参数的XMT-A模式而产生的。 The bit stream is based on the XMT-A defined pattern "BitWrapper" node and parameters generated. 并且,如下所示,通过使用XMT-A模式以及XMT2BIFS和XMT2MUX样式表230和220,来产生将4皮输入到MPEG-4编码器中的".scene"和".mux" 文件。 As shown below, by using the XMT-A mode, and XMT2BIFS XMT2MUX stylesheets and 230 and 220, to produce the sheath 4 is input to the MPEG-4 encoder ".scene" and ".mux" file.

将".scene"和".mux"文件输入到MPEG-4编码器并且通过BIFS编码器250产生".bifs/.od"文件。 The ".scene" and ".mux" files input to the MPEG-4 encoder and generates ".bifs / .od" BIFS encoder 250 files. 将该".bifs/. od"文件(或比特流)和"mux"文件输入到MP4编码器260,从而获得".mp4"比特流。 The ".bifs /. Od" file (or bit stream) and "mux" file 260 is input to the MP4 encoder to obtain a ".mp4" bitstream. 在MPEG-4播放器的屏幕上可视化该"mp4"文件。 MPEG-4 player on the screen of the visual "mp4" file. 第三,参考附图2和6将描述,通过使用参数而将原始数据压缩成比特流并且使用URL传输比特流的方法的实施例。 Third, with reference to Figures 2 and 6 will be described by using the parameters to the raw data into a bit stream compressed using the method of Example URL transmission bit stream.

图6说明一种使用参数,将有关诸如杯子之类的对象A的3D数据(例如几何结构信息、连接信息和颜色信息)压缩成比特流并且经由"BitWrapper" 节点所定义的URL来传输比特流的方法。 FIG 6 illustrates a parameter, the 3D data (e.g., geometry information, connection information, and color information) relating to the object A such as a cup or the like and compressed into a bit stream via a URL "BitWrapper" node of the defined transmission bit stream Methods. 该方法不同于将3D数据压缩成比特流并且通过緩沖器传输比特流的方法。 This method differs from the 3D data compression method into a bit stream and the transmission bit stream through the buffer. 更准确地说,在该方法中,在"BitWrapper"节点中定义例如12的URL ID,具有诸如URL ID的ObjectDescriptorID的"BitWrapperEncodingHints"能够指定有关对象A的3D数据的被压缩比特流表示的位置,也就是"bunny-15000-tcp.m3d"文件,并且基于"BitWrapperEncodingHints"字段传输被压缩的数据。 More specifically,, URL ID defined in example 12 "BitWrapper" node, in this process, such as having the URL ObjectDescriptorID "BitWrapperEncodingHints" ID capable of specifying the 3D data about the object A is represented by a compression of a bit, i.e. "bunny-15000-tcp.m3d" file, and the data "BitWrapperEncodingHints" field based on the compressed transmission. 接下来,有关3D数据的被压缩比特流表示的位置的信息包含在有关".mux"文件的信息中。 Next, the relevant 3D information of the position data of the compressed bit stream representation of information contained in the ".mux" file. 有关".mux"文件的位置信息在"ObjectDescriptorUpdate"也就是"BitWrapper"节点的URLID中描述。 Location information about ".mux" file described in URLID "ObjectDescriptorUpdate" is "BitWrapper" node. 有关".mux"文件的位置信息链接到,有关对象A的3D数据的被压缩比特流表示的位置信息,也就是"bu皿y-15000-tcp.m3d"文件。 Position information about ".mux" file linked to the position information about the object represented by the bit stream A 3D data is compressed, i.e. "bu dish y-15000-tcp.m3d" file. 有关3D数据的被压缩比特流表示的位置信息链接到3D数据的被压缩比特流表示。 For information bit stream indicates the position of the 3D data is linked to the 3D compression data compressed bitstream representation. 从而,经由URL来传输"bunny-15000-tcp.m3d"文件的比特流表示。 Thus, the URL is transmitted via the "bunny-15000-tcp.m3d" represents a bit stream file.

当在输入到XMT分析器210的图2的输入XMT文件200中说明图6的方法时,XMT分析器210基于XMT-A模式240,使用XMT2BIFS和XMT2MUX样式表230和220,将有关".mux"文件的位置信息和场景数据一起插入到". SC6I16 "文件,并且传输该". scene"文件。 When the input to the XMT parser 210 of FIG. 6 illustrate the method of FIG input XMT file 200 2, 210 XMT parser 240 based on the XMT-A mode, and the use XMT2BIFS XMT2MUX stylesheets 230 and 220, the relevant ".mux "insertion position information and scene data file together". SC6I16 "file, and the transfer." sCENE "file. 所述的".mux"文件包括一个通过包含在MPEG-4编码器中的BIFS编码器250所产生的".bifs/.od"文件。 It said ".mux" includes a file by including the MPEG-4 encoder generated by the BIFS encoder 250 ".bifs / .od" file. 同样,". mux"文件包含有指定表示有关对象A的3D数据的比特流的位置的"bunny-15000-tcp. m3d"文件。 Similarly, ". Mux" represents the specified files contain "bunny-15000-tcp. M3d" bitstream file location data concerning a 3D object A.

当有关3D数据的比特流表示的位置信息和".bifs/. od"文件被输入到MP4编码器260时,在MPEG-4播放器的屏幕上产生并显示一个作为比特流文件的".mp4"文件,其中在".mux"文件中指定3D数据的比特流表示。 260, and generates a bitstream file as displayed on the MPEG-4 player's screen when the 3D positional information about the bit stream data representation and ".bifs /. Od" files are input to the MP4 encoder ".mp4 "file, which in the" 3D data specified .mux "represents a bit stream file.

通过实施例3将更加详细地描述图6的方法。 By the method of Example 6 will be described in more detail 3.
