Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Whole description, it is clear that described embodiment is only a part of embodiment of the present invention, the embodiment being not all of, based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not paid
Example, belongs to the scope of protection of the invention.
A kind of method controlled in real time DVE is provided in the embodiment of the present invention one, was implemented as shown in Figure 1
Journey is as follows：
Step S101：Obtain the input video source channels and sample area for being currently needed for being adjusted and changing.
Step S102：Choose the DVE templates of scene and obtain the original DVE information in the DVE templates.
Step S103：Call corresponding sample area in the sample list that current engineering designed.
Step S104：According to the input video passage and sample area applied after current change, bottom modification is rendered original
DVE property parameters, update the sample area in DVE templates, form new DVE, realize control DVE in real time.
Embodiments of the invention can require accurate adjustment DVE size and position before real-time broadcast according to picture and broadcast
Put, the cited input video source channels of switching and sample area etc. can realize DVE real-time control.
The DVE real-time control methods in embodiment one will be described in detail for the embodiment of the present invention two, such as Fig. 2 institutes
Show.
Step S201：From DVE templates, template scene tree is traveled through, the original DVE information in template is obtained.Scene template
In DVE can select any one, and the size of the original video sampling used in original DVE information records DVE.
Step S202：Sample area design, each sample area are carried out to each road video source input channel currently supported
It can number and be marked with different sequence numbers and be stored with tabular form.The multiple sample areas of one passage correspondence, user can be with
Sample area is added manually to meet requirement.
Specifically, sample area does not become with scene template, and broadcast engineering-level is stored in, each broadcasts engineering
There is a video input list in file, have per road video input passage in a sample list, sample list and record sequence number
With corresponding sample area.For example, serial number A0, the A1 of the sample area stored in the sample list of A roads video input passage,
A2...... then A0 represents first sampling sequence number for original size, A1 (left-top, right-top, left-bottom,
Right-bottom second sampling sequence number on video input A roads and four point left sides of corresponding sample area size) are represented
Upper, upper right, lower-left, lower right coordinate.
Step S203：Call some sample area in the sample list designed in current engineering.Carried for one
Sample list when the DVE attributes of DVE templates reselect sample area as shown in figure 3, can be selected according to actual needs
Select the control that any one sample area in A0, A1...... and B0, B1...... carries out DVE.
Step S204：When receiving broadcast instruction, the original DVE information that first backup template is carried renders bottom acquisition
Sample region thresholding in step S203, changes DVE property parameters, adjusts DVE size and location.
Step S205：Input video source channels are adjusted, and input the sample area of change, are regarded according to currently employed input
Frequency source channels and sample area recalculate DVE parameters, update DVE sample area and effect, the life rendered
Into the new DVE of formation is broadcasted.
Step S206：After scene comes out from rendering, DVE is automatically restored to original DVE information.
It is preferred that, input video source channels used in template can be provided in DVE windows in the embodiment of the present invention
Indicator lamp indicate, and in the window carry out video source multiple sample areas setting, can thus observe in real time
The content in input video source, preferably coordinates and broadcasts.
By embodiments of the invention, accurate adjustment DVE size can be required according to picture and broadcast before real-time broadcast
And position, the cited input video source channels of switching and sample area etc., DVE real-time control, and energy can be realized
