The invention discloses a method, a device and a system for realizing rendering broadcast. The method comprises the following steps of: connecting one proxy server between a rendering broadcast server and a broadcast control terminal, and storing a broadcast preparing command in a broadcast preparing list form after monitoring the broadcast preparing command sent by the broadcast control terminal; receiving a broadcast command sent by the broadcast control terminal; analyzing the broadcast command sent by the broadcast control terminal, and searching the broadcast preparing command corresponding to the broadcast command sent by the broadcast control terminal in the broadcast preparing list; acquiring the broadcast content corresponding to the broadcast preparing command from the proxy server according to the broadcast preparing command; and forwarding the broadcast command to the rendering broadcast server, and broadcasting the broadcast content corresponding to the obtained broadcast preparing command by the rendering broadcast server. The broadcast command in the method can be transmitted to the rendering broadcast server after certain delay or meeting certain requirement, so that the accurate broadcast of the broadcast content is realized.
Description
technical field [0001] The invention relates to the technical field of graphics and text in video production, in particular to a method, device and system for realizing rendering and broadcasting. Background technique [0002] In the video graphics and text packaging system, when rendering and broadcasting video content, the rendering and broadcasting server receives rendering commands and renders each scene layer by layer. However, in practical applications, there is often a playback control terminal. The playback control terminal prepares all layers, scenes, and replaced resources, and then sends control commands in sequence according to time requirements, and the rendering and broadcasting server performs rendering control commands. Parsed, then rendered. [0003] In the prior art, the playback control terminal directly connects to the rendering and broadcast server through a direct network socket, and the control terminal sends template information, scene playback prepa...
