Description
Technical field
The present invention relates to a kind of Large video meeting split screen system and method for realizing 2+N.
Background technology
With the construction continuously and healthily of Chinese communication network, China's Telecommunication's level has been increased substantially, and is each row
The information interchange of each industry provides reliable guarantee.In many communication services, Remote Video Conference business is increasingly shown
Good growth momentum.
Net meeting system is a simply complicated system, and it is used simply, but to adapt to each meeting
The situation of scene but seem complicated.Especially in span mode this part.Video conference span mode, is the picture participant
Project on shared screen cover.
Especially large-scale Remote Video Conference is higher to screen-picture Spreading requirements.Should give prominence to the key points main meeting-place and
The video pictures of spokesman, show the video pictures of other sub-venues again, and also to ensure the quality of video pictures simultaneously,
Such as picture the ratio of width to height etc..
The video conference producer of current main flow is a lot, and various span mode can solve most of Remote Video Conference
Demand.But for large-scale Remote Video Conference, existing span mode still can not fully meet demand：Traditional 1+0
Span mode, sets main meeting-place as full screen display, carries out video conference with the forms of broadcasting, screen only shows one big picture, its
He is not appeared on screen then the picture of sub-venue.This most basic span mode can maximize main meeting-place of giving prominence to the key points,
But the meeting-place picture of display is less, and when being not same meeting-place in main meeting-place and main spokesman, in switching signal
Source can be cumbersome.Traditional 4 grade split screens, the split screens such as 9, the split screens such as 16, principle are, by screen mean allocation, to show more
Meeting-place situation.But do not have main body in this case and protrude, it is difficult to differentiate main meeting-place, spokesman and sub-venue.
In addition, for convention, the video conference span mode of existing 1+N (N≤12) is temporarily solved
Large-scale Remote Video Conference demand.And main meeting-place picture is arranged on most awake destination locations.1+N span mode exists maximum
Leak is exactly, when using this pattern, and screen can have that covering is discontented, that is, black surround occurs, shadow is so understood
Ring the visual effect of beholder.And, therefore the ratio of width to height of video pictures can be automatically adjusted, with original 16:9 form
It is otherwise varied, cause picture to stretch, influence viewing.Furthermore, current many Remote Video Conferences no longer limit to a main meeting-place,
But the form of main meeting-place+spokesman (or double fluid), therefore, the picture given prominence to the key points should not only one of which.
The content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of Large video meeting for realizing 2+N
Split screen system and method, it can realize that the display of Large video meeting carries out more humane split screen.

Second viewing area is shown；Multiple points of videos are respectively sent into multiple display subregions to be shown.
It can be drawn from above design, compared with existing span mode, the present invention has the following advantages that：
Compared to existing 1+N span mode, this is designed as 2+N patterns, and having more one than original pattern gives prominence to the key points
Picture, for highlighting spokesman or double-current interface.In the case where main meeting-place and spokesman are not same meeting-place,
Cumbersome manual switching work can be removed from.
Do not influence on the premise of protruding main meeting-place and spokesman meeting-place, show enough sub-venue picture (18 branches
Field picture), each sub-venue picture size is consistent.And screen display all over the screen, occurs without the vacant situation for staying black surround of screen.
Ensure that each screen resolution is consistent.Assuming that screen is the 16 of the 1080P of standard:9 display screens, resolution ratio is
1920x1080.By calculating, it can draw, the resolution ratio in main meeting-place and spokesman meeting-place is 960x540；The resolution ratio of sub-venue
For 320x180,；It is 16:9 standard proportionals.Picture is there will be no under this split screen design due to adjust automatically to occur
Stretching or compression phenomena.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection domain of the claims in the present invention
Within.
