Remote desktop synchronizing method in ubiquitous environment

Abstract

The invention discloses one remote desk plane simultaneous method in common environment, which comprises the following steps: a, when servo screen generates changes, servo gets minimum rectangle composed of sub area and change area; b, dividing the sub area into macro block and then into a, b, and c sub areas; c, regularizing sub area to become rectangle; d, servo sends the screen change information to customer end to form relative sub area. The invention considers the adjacent two frames time redundancy for process by types.

Description

technical field [0001] The invention belongs to the field of computer applications, and in particular relates to a remote desktop synchronization method ASTR (The Association of Spatio-Temporal Redundancy Reductions) in a pervasive environment. The method is particularly suitable for pervasive environments with limited bandwidth and client computing capabilities. Background technique [0002] In recent years, many server-based computing (SBC, server-based computing) applications have emerged, such as VNC, PCAnywhere, and Netmeeting, which allow us to access resources in remote computers as easily as accessing local machines. In these applications, the compression and transmission of graphical screens are the most critical steps in the remote screen synchronization (RSS, remote screen synchronization) method. However, server screens usually change frequently, generating a large amount of image data, and the transmission of this data consumes a large amount of bandwidth. In o...

Problems solved by technology

However, the network bandwidth of the ubiquitous environment is usually relatively narrow and unstable, so the transmission of large amounts of screen compressed data is increasingly becoming a bottleneck

On the other hand, since the image to be transferred is a series of continuously changing regions of the screen in a user interface style, there is usually a large amount of temporal redundancy between two consecutive screen images
