Image Communication Of Computer Remote Maintenance

The image communication of the screen of a computer is of great importance in the system of computer remote maintenance. The server-client mode based on the protocol of TCP/IP on Internet is adopted to transmit the information of the screen. In this paper, some common technologies of data compression and standards of image compression are analyzed, algorithms such as Huffman, LZW and arithmetic are implemented. An algorithm named Rectangle Image Block Compression is presented for the screen image compression. The algorithm of RIBC divides the screen image into segments based on the concept of Region-based. Then, the segments are compressed. An advanced algorithm of the scaled RIBC code is presented under the requirement of computer remote maintenance. As for the ratio of the compression, this algorithm is proved more efficient than the other algorithms in the compression of screen image. A software scheme of the object-code of windows is designed for the compression of inter-frame.
