有许多专业术语.我朋友最近忙,没时间翻译,托我翻.我也不太懂...求高手帮忙.原文如下:
Standardized in 1991, MPEG-1 is the oldest of the digital video standards produced by the MPEG group. The purpose of MPEG-1 was to provide technologies and algorithms for the efficient compression of digital video. This was done to facilitate the transport and storage of digital content, while maintaining quality.
The importance of the technologies and concepts defined by MPEG-1 for the compression and transport of video is that they form the basis for later standards.
MPEG divides videos into sequences that group together similar frames. A frame is nothing more than a still image. The frames,in each sequence, are then divided into groups of I, P and B-Frames. These frames are important in determining how compressed a frame can be, the chance of error propagation, whether it represents inter-frame or intra-frame data, and the encoding order.

Answer 1

　　1991年被标准化,MPEG-1是历史最悠久的数字视频标准所产生的MPEG组。MPEG-1的目的提供了有效技术和算法压缩数字视频。这样做的目的是便利的运输和储存的数字内容,同时保持质量。
　　MPEG-1所定义的技术和概念的重要性在于压缩和传递的视频是为后来的标准奠定了基础。
　　MPEG将视频分成一组相似的帧。只不过每一帧是静止图像。在每个帧序列,然后分成几组的I,P、B-帧。这些帧在决定怎样压缩每一帧是非常重要的,不管它代表帧间或内帧数据,编码的错误概率都是一样的
