Embodiment
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only
The embodiment of a part of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, should all belong to the model that the present invention is protected
Enclose.
It should be noted that term " first " in description and claims of this specification and above-mentioned accompanying drawing, "
Two " etc. be for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so using
Data can exchange in the appropriate case, so as to embodiments of the invention described herein can with except illustrating herein or
Order beyond those of description is implemented.In addition, term " comprising " and " having " and their any deformation, it is intended that cover
Lid is non-exclusive to be included, for example, the process, method, system, product or the equipment that contain series of steps or unit are not necessarily limited to
Those steps or unit clearly listed, but may include not list clearly or for these processes, method, product
Or the intrinsic other steps of equipment or unit.
In correlation technique, there are two kinds of implementations for conference system at present：
First, disposed by special Multi-Party Conference hardware device.Carried out by way of hardware is stacked to multi-source number
According to carrying out handling hardware-accelerated with big data quantity, internetworking, Ke Yida are carried out using internet special line between Multi-Party Conference
To the display of HD video double fluid and the clear lossless display of computer screen.
The 2nd, software is installed on Mobile portable equipment.By setting up Conference server on public network, Multi-Party Conference passes through hand
Software is installed on the common apparatus such as machine or tablet personal computer, conversated access, Ke Yishi using WiFi or mobile 4G networks
The Mobile portable of existing meeting access.
But, there is problems with above two scheme：
For the first scheme, hardware device deployment is complicated, it is necessary to which the engineers and technicians of specialty could complete；Multi-party meeting
During view, due to the access of multi-source, transmitted data on network amount is very big, needs special hardware-accelerated and matched Netowrk tape
It is wide；
For second scheme, common apparatus process performance is limited, and the conference traffic encoding and decoding of multi-source access are complicated, meeting
Discuss quality high to network dependency degree, it is difficult to ensure Consumer's Experience；Computer picture carries out lossy compression method, it is impossible to which meeting will to image
Seek the demand of the higher industry of quality (for example, medical imaging)；The delay of meeting Reverse Turning Control is big.
It is different from traditional video conference, the computer graphic that the embodiment of the present invention can export computer equipment video card
Picture, i.e. computer screen screenshotss carry out IPization, and accomplish long-range display.Conventional video conferencing function is carried out according to scene whole
Close, accomplish that the camera acquired image of nearly remote portable equipment or video letter can be shown on one piece of display screen
Breath, and the image of the computer equipment output of the clear lossless display near-end of energy.Multi-source is inputted to cloud server data flow
Each actual equipment output data code stream, server carries out screen partition according to display end window size.By actual displayed window
Size resolution adaptation, the data flow for completing audio frequency and video window is effectively compressed transmission.And computer screen information is in conference scenario
It is more crucial and important, do Lossless Compression transmission for the image of video card output display, it is ensured that it is clear that computer picture is shown
It is clear lossless.After server display fusion, the data code flow equivalent to a source is only exported.Ensuring the clear nothing of key message
On the premise of damage, the transmitted data on network code check and the network bandwidth of actual scene are reduced.
The Back Control Channel of remote portable computer and near-end display output computer is got through, by remote portable computer
Control action, implication and the screen location information control operation corresponding to near-end display output computer of USB device make one
One mapping.Need exist for by the screen resolution of two computers, control information member language and Synchronization Control agreement make it is assorted after,
Reverse Turning Control function can really be realized.
