Abstract

In this paper we design a novel transcoding algorithm to transcode and compress a JPEG or MPEG bitstream to a fully embedded one. Due to the efficiency of multigrid embedded (MGE) coding used to code non-zero quantized DCT coefficients, it actually compresses JPEG or MPEG bitstreams from 9% to 30%. This "transcompression" method has many applications for the Internet and multimedia networks. Since most "original" images or video files stored on computers around the world are in JPEG or MPEG formats, our algorithm provides a simple and efficient way to redistribute pictures/video files across the Internet.

JPEG转换压缩器和互联网应用程序

本文设计了一种新的转码算法，将JPEG或MPEG码流转码压缩为完全嵌入的码流。由于用于编码非零量化DCT系数的多网格嵌入(MGE)编码的效率，它实际上将JPEG或MPEG比特流从9%压缩到30%。这种“转压缩”方法在Internet和多媒体网络中有许多应用。由于世界上存储在计算机上的大多数“原始”图像或视频文件都是JPEG或MPEG格式，我们的算法提供了一种简单有效的方法来通过互联网重新分发图片/视频文件。
