【摘要】 该文介绍了利用韩国INTIME公司的压缩芯片IME6400,设计并实现了基于MPEG-4的图像压缩系统。静止的图像采用较低的码流,运动的图像采用较高的码流的可变码流压缩方法,在相同环境和相同码流的条件下,与采用其他压缩算法的系统相比,具有画面质量高,相同的画面进行网络传输实时性好等优点。更多还原

【Abstract】 By choosing hardware compression chips from INTIME Corporation(Korea),the system can process the picture in high speed and real time.The system has variable bit rate,hence low bit rate for still pictures and high bit rate for moving pictures.In this way,the system achieves both the high picture quality and reduced storage space.By comparison with other video storage systems in the same environment,the result shows that this system has higher picture quality and real time quality for web transmission.更多还原
