Real-time software-based moving picture coding (SBMPC) system

摘要

A novel moving picture coding system, called the software-based moving picture coding system, is presented in this paper. In this coding system, two new techniques, modified block truncation codes and multiresolution-in-time sampling, are used for real-time encoding and decoding of the moving pictures. The modified block truncation codes can process image data with three times faster and two times higher compression ratio than those of the traditional ones. The multiresolution-in-time sampler samples the image blocks with variant sampling rates, which depend on the activities of image blocks. This technique can make the coding process faster and the compression ratio higher. By using these techniques, the software-based moving picture coding system can compress moving pictures (video) under the real-time constraints of video applications, such as videophone/videoconference, without using any expensive compression chips.
