Remote display processing method based on server end/client end structure

Abstract

This invention disclosesd a kind of remote display processing method based on server / client. On the server end, it adopts the especial increment compress scheme among frames and gives up the complicated calculation way in the traditional scheme compress among frames. On the client end, it adopts the way of increment refreshing to show pictures, only refreshes the metabolic parts, change part, refresh part. It can improve the refreshing speed of long distance desktop greatly, while reducing the resource occupancy factor.

Description

technical field [0001] The invention relates to a computer display processing method, in particular to a remote display processing method based on a server / client structure. Background technique [0002] The existing remote control display technology generally adopts the structure of Server\Client. The server side is mainly used to collect image signals, judge the changes of the signals, compress and then transmit them. Because it is mainly aimed at computer images on the Internet The control display of the control shows that the compression method adopted is generally lossless compression. Considering the limitation of transmission bandwidth on the Internet, the main purpose is to improve the compression ratio; the current lossless compression encoding methods of images mainly include the following types: run-length encoding technology, huffman coding compression technology, dictionary compression technology, arithmetic compression technology, MPEG compression technology (l...

Problems solved by technology

If an image is composed of many large areas with the same color, the compression efficiency of this method will be amazing. However, this algorithm has a fatal flaw: if the colors of every two adjacent points in the image are different, then The amount of data will double

At the same time, he adopted the idea of ​​dictionary compression algorithm, which not only compresses data values, but also compresses value sequences. This algorithm can achieve a higher compression ratio, but the algorithm is too complicated, and the compression and decompression speed will be greatly affected.

MPEG compression technology is also mainly a compression algorithm designed to improve data transmission in a narrowband environment. It includes intra-frame compression and inter-frame compression. The intra-frame compression algorithm is based on DCT coding technology, and the inter-frame compression algorithm uses prediction methods. , Compensation method and motion compensation method and other technologies; MPEG algorithm is relatively complex, which is very effective for narrowband transmission, but the result of complex calculation is that the CPU resource is very large and the system resource consumption is serious.
