Remote management system and method thereof

Abstract

The invention provides a remote management system and a method thereof. The remote management system comprises an image capture module, a processing / comparing module, an image coding module and a transmitting module. The image capture module transfers an active image signal output by a controlled computer to a series of static images based on a sampling frequency. The processing / comparing module further divides the static images into a plurality of comparing areas and compares the difference of the former and latter static images so as to find a change area with pixel change in the comparing area. The comparing area is divided into a plurality of comparing groups, each of which corresponds to a display zone in a webpage display area of a web browser. The image coding module transfers the pixels of all the comparing zones in the comparing groups belonged to the change area into coding data. The transmitting module transmits the coding data to a webpage browsing device based on the request of the webpage browser, and thereby the webpage browser can update its corresponding display area based on the coding data, and display active images, corresponding to the active image signals output by the controlled computer.

Description

technical field [0001] The present invention relates to a remote management system and its method; specifically, the remote management system and its method of the present invention enable the client computer to directly use the Display the dynamic images output by the controlled computer. Background technique [0002] A KVM switch (Keyboard-Video-Mouse Switch; KVM Switch) is connected between the client central control device and multiple controlled computers, allowing users to control multiple controlled computers through a set of keyboards, screens and mice. computer. A so-called Over-IP KVM switch is a KVM switch with a network interface, which couples a client computer to one or more controlled computers via a network. [0003] In order to enable the user of the client computer to operate the network KVM switch and communicate with the controlled computer, a management interface must be provided on the client computer for use by the client computer. In the traditiona...

Problems solved by technology

Although related web standards such as HTML 5 support moving images in specific formats (such as MPEG4), in fact, current browsers do not support these specific formats due to the involvement of intellectual property rights.

Moreover, this image format is incompatible with the control of keyboard and mouse, so in order to display dynamic images in the web browser, it is still necessary to add additional plug-in programs or call additional applications from the web page as mentioned above.

In addition, since the design of plug-in programs varies with the attached web browsers and underlying operating system platforms, manufacturers of network KVM switches must It is necessary to develop plug-ins or applications for different web browsers and operating systems, and the manpower and material resources consumed will be a big burden for KVM switch manufacturers
