Abstract

The invention discloses a method and device for real-time control of a DVE, which acquires an input video source channel that needs to be adjusted and changed at present and a sampling area of ​​the input video source channel; selects a DVE template of a scene and acquires the DVE template The original DVE information in the current project; call the sampling area in the corresponding DVE template in the sampling list designed by the current project; according to the input video source channel and the sampling area of ​​the input video source channel, render the bottom layer to modify the original DVE information The property parameters of the DVE template are updated to update the sampling area in the DVE template and control the DVE in real time. The invention can precisely adjust the size and position of the DVE according to the picture and broadcasting requirements before real-time broadcasting, switch the referenced input video source channels and sampling areas, etc., and realize the real-time control of the DVE.

Description

technical field [0001] The invention relates to the technical field of graphic and text production in the field of radio and television, in particular to a method and device for real-time control of a digital special effect DVE. Background technique [0002] In the real-time broadcasting system, if digital video special effects DVE images are required, the scenes that have been designed for DVE need to be loaded, but often the images required for broadcasting cannot be clearly understood during design. A few seconds before the broadcast, the size or area of ​​the DVE needs to be adjusted according to the live situation. [0003] In the prior art, the DVE can only be designed by knowing the actual broadcasting situation in advance. And adopting the existing DVE control method, the changeability is small, but the applicability is poor. Once it is broadcast, it cannot be corrected in time. It is not possible to make a variety of different effects, and it is necessary to prep...
