The transcoding technology can be divided into two types : one is to transcode the video stream from one format to another , which is called homogeneous transcoding ; the other is heterogeneous transcoding , which transcode the compressed video from one standard to another 主要分为两大类,一类是在同一视频编码标准中转换,另一类是在不同标准之间转换。本文以数字电视转码为背景,主要研究了hdtv ( 1920 1080 )到sdtv ( 640 480 )的转码。
The transcoding of compressed bitstreams is to transcode a compressed video stream from one format or standard to another . based on heterogeneous transcoding , the transcoding between h . 263 and mpeg - 4 is researched in this paper , including the transform of bitrate and space resolution 本文以不同标准之间的视频转码为背景,主要研究了h . 263与mpeg - 4两种标准之间的视频转码,包括空间分辨率转换和码率转换的内容,并在pc上实现了转码系统。
The transcoding technology can be divided into two types : one is to transcode the video stream from one format to another , which is called homogeneous transcoding ; the other is heterogeneous transcoding , that is transcode the compressed video from one standard to another 所谓的视频转码就是将一种格式的压缩视频数据处理成更适应于特定应用的另一种格式的压缩视频流。主要分为两大类,一类是在同一视频标准中转换,另一类是在不同标准间转换。
In this case , you could parameterize your stylesheet to generate a smaller html document for a wml device , which transcoding technology would then transcode to wml see the article by alan booth and kathryn britton , spinning your xml for screens of all sizes , published on ibm developerworks 在这种情况下,您可以为样式表设置参数以便为wml设备生成较小的html文档,然后代码转换技术将该样式表代码转换成wml (请参阅alan booth和kathryn britton发表在ibm developerworks上的文章
And the transcoding technology can be divided into two types : one is to transcode the video stream from one format to another , which is called homogeneous transcoding ; the other type is heterogeneous transcoding , that is to transcode the compressed video stream from one compression standard to another . aim at the homogeneous transcoding , the second chapter concentrates on the format transcoding of compressed video stream compliant to the same compression standard 主要可以分为两大类:一类是把编码数据流从适合某一传输环境的压缩形式转换成适合于另一传输环境的压缩形式,称为同类视频转码;另一类是把压缩数据流从某一种标准转换成另一种标准,称为不同种类视频转码。
