Description
Technical field
The present invention relates to computer network communication technology fields, more particularly to one kind being based on network communication and audio/video coding
The software KVM management system of technology.
Background technology
With network and information-based construction, various computer equipments are more and more, have to these equipment
Effect management and operation are also increasingly difficult to.In order to solve this problem, successively there is the KVM switcher of hardware type, and be based on
The KVM switcher etc. of network.These switch are all individual hardware devices, the video output by computer and keyboard, mouse
Input by way of shared, achieve the purpose that an equipment management multiple stage computers equipment.This mode needs to buy KVM
Switch, and various wiring are needed, virtually improve difficulty and old of the maintenance of implementation.
There is the KVM that some software modes are realized to switch software on the market, these softwares are realized by way of shared
A set of keyboard and mouse is come the multiple stage computers that control, but every computer is required for connecing a display equipment, in computer number
When measuring more, although how can effectively to be disposed by a set of keyboard and mouse control computer, more display equipment
At prodigious problem, while also bringing prodigious expenses.When system scale is larger, this mode equally has very
Big inconvenience.
The present invention is mainly to solve the problems, such as that the high cost of hardware type KVM and wiring are complicated, while solving software KVM
It is shared can only to carry out mouse-keyboard, every computer must external-connection displayer the problem of.While solving these problems, provide
The respective not available operating feature of more convenient hardware KVM and software KVM, whole system deployment is convenient and simple, is easy
Extension, operation are flexibly convenient.
Invention content
The purpose of the present invention is to solve disadvantage existing in the prior art, and the one kind proposed be based on network communication and
The software KVM management system of audio/video coding technology.
To achieve the goals above, present invention employs following technical solutions：
Software KVM management system based on network communication and audio/video coding technology, including service terminal software and client software,
The service terminal software includes server-side registering unit and server-side logs in unit, and server-side logs in unit and is connected with client behaviour
Elect interface, and client operation selection interface includes multiple client, and client is connected with client master by network bi-directional
Machine, client software is installed on client host, and client host, without installing display, client host is connected with control
Unit, control unit are connected with audio coder, and audio coder is connect with client host.
Preferably, the server-side logs in unit and is used for safeguard protection, avoids stranger from arbitrarily logging in management system, to protect
Hinder whole system safety, the information that audio coder is used to operate in client host is passed by the form of video plus audio frequency
It is defeated by service terminal software.
Preferably, the audio coder utilizes linear prediction one by one to image information sample decorrelation, to some pixel
S0For, it uses the weighted sum " ... " of some neighbouring pixel intensities as valuation, to S0It is predicted, S0Difference between " ... "
Value S (n) is exactly to predict error, due to adjacent pixel and S0Between there are correlations, the statistical average energy of difference just to become very little,
Therefore, the transmission of error image need to can be only realized with a small amount of number, there are mainly three types of prediction techniques for image forecasting encoding, 1.
One-dimensional fixed prediction：S1Or S2To S0Prediction, weighting coefficient are fixed and are less than 1,2. the fixed prediction of two dimension:When prediction valuation takes
S1And S2Mean time, referred to as two-dimentional consensus forecast, and when prediction valuation takes ...=S1+S2-S3When, referred to as two dimensional surface is pre-
It surveys, 3. condition transmits inter-prediction：Use the pixel of former frame same plane position as prediction valuation, for only a small amount of activity
Image, be equal to zero or very little there are about 70 or more percent frame difference in picture, therefore these differences can be given up and not pass,
Since whether the transmission of frame difference is more than some threshold value as condition using its amplitude, also known as condition transmits inter-prediction.
Preferably, the client operation selection interface is connected with the decoding displaying of the information for encoding audio coder
Video information is used for the observation of server-side.
Preferably, the duplication operation transmission carried out in the client is to server-side, the shear plate synchronizing information of client
To server-side, two clients create temporary link.
Preferably, the audio coder is sent to client software after being encoded video plus audio frequency, and client is soft
The family end that the information of coding is issued service terminal software by part by network operates selection interface, thus will under display unit decoding
Information is shown in server-side.
The beneficial effects of the invention are as follows：
1, the present invention can greatly simplify the network arrangement of multicomputer, it is only necessary to install main frame, carry out network
It can be carried out operating after connection, need not be every allocation of computer display, also need not be every allocation of computer KVM
Hardware device greatly reduces cost, while greatly simplifiing the structure and line of system；
2, pass through this system software, it is only necessary to which a computer, display and a set of keyboard and mouse can be completed to operate, together
When network structure there is good autgmentability, without the complicated network configuration of hardware type KVM, also there is software type KVM not have
Standby remote desktop display function.
