Linux桌面图形序列的压缩与传输

Compression and Transmission Scheme of Linux Desktop Graph Sequences

提出了一种基于网格的无损编码方法对Linux桌面图形序列进行压缩和传输;并采用C/S模式实现了将Linux桌面屏幕向Windows平台的传输,其中服务器程序运行于Linux平台,客户程序运行于Windows平台,双方利用Socket进行通信。为了提高数据的传输效率,采用了Huffman算法和RLE算法对网格数据进行压缩和解压。实验结果表明,程序运行可靠,能够满足实际应用的需要。

In order to compress and transmit the Linux desktop graph sequences, a lossless compression arithmetic based on gridding is put forward in this paper, According to this arithmetic, two programs based on Client/Server mode are designed. The server program runs on the Linux platform and captures Linux screen while the client program runs the Windows platform and redisplays the Linux screen. They communicate with each other by means of the Socket. To improve data transmission efficiency, Huffman and RLE algorithms are adopted in this paper. The experimental results show that the programs run reliably and can meet actual application＇s demands.
