Problems solved by technology
[0005] The main disadvantage of adopting the method of black field generator and frame synchronization processor is: in the face of signals of different video display formats, it is necessary to select corresponding frame synchronization processing devices that support different video display formats, and after frame synchronization processing, it is still Signals in different video display formats have different resolutions, refresh rates and other indicators. Switching between two different signals will cause color distortion and various image loss, distortion, jitter and other problems, resulting in live broadcast accidents happened

The embodiment of the invention provides a broadcasting directing control system and a broadcasting directing method, belonging to the technical field of broadcasting directing. In the system, a broadcasting directing instruction is obtained through a center control device, a first instruction is sent to a video matrix selecting and switching device according to the broadcasting directing instruction, the video matrix selecting and switching device transmits a target video signal to a splicing and fusion processing device according to a first instruction, the center control device sends a second instruction to the splicing fusion processing device according to the broadcasting directing instruction preset duration later after sending the first instruction, and the splicing and fusion processing device outputs the target video signal according to the second instruction, thus, after waiting for disappearance of phenomena, such as image black screen and jittering, generated when the videomatrix selecting and switching device switches unsynchronized video signals of two paths of frames, the splicing and fusion processing device is further controlled to output the target video signal,consequently, the phenomena, such as image black screen and jittering, generated when the video matrix selecting and switching device switches unsynchronized video signals of two paths of frames can be hidden, and a signal switching process watched by audiences is undistorted and in smooth transition.
Description
technical field [0001] The present invention relates to the technical field of broadcasting, in particular to a broadcasting control system and method. Background technique [0002] With the rapid development of radio and television technology, video signal display formats are gradually developing towards high-definition or even ultra-high-definition. Time period, real-time live broadcast occasions for important audiences (such as some high-level conference live broadcast, military exercise live broadcast, etc.), the display error of one frame of image in the live broadcast will be characterized as a serious live broadcast accident, in order to ensure the smoothness and Stability. As the core of broadcast and TV broadcasting, the director and display control system is facing huge challenges. [0003] In live broadcast tasks, multiple cameras are generally used to shoot, so that the program has the characteristics of multiple angles and scenes, and the performance is more co...
