Abstract: 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
