标准范围

ISO/IEC 14496-19:20 04规定了作为MPEG-4编码的视听呈现的一部分的合成纹理数据的传输。更具体地说,它定义了:合成纹理的数据结构;合成纹理的动画方法;合成纹理流用于创建非常低比特率的合成视频剪辑。使用基于关键帧的骨架动画构建合成纹理剪辑,该骨架动画影响真实感纹理,其颜色信息由方程建模。

ISO/IEC 14496-19:2004 specifies the transmission of synthesized texture data as part of the MPEG-4 encoded audio-visual presentation. More specifically, it defines:

  • The data structures of synthesized texture;
  • The animation methods of synthesized textures; and
  • The coded representation of synthesized texture data streams.


Synthesized texture streams are used for creation of very low bit rate synthetic video clips. Synthesized texture clips are built using key frame based animations of skeletons that affect photorealistic textures whose color information is modeled by equations.
