Abstract

The invention discloses a method and a device for removing a clock scene in real time. The method comprises the following steps of: setting clock parameters for removing the clock scene, establishing a synchronization mechanism with a plug-in layer, and performing synchronous binding; receiving an accurate numerical value of time which is displayed in real time in each frame transmitted by the plug-in layer; and comparing whether the accurate numerical value meets the requirement of the clock parameters, if so, removing the clock scene and awakening other predefined operations, and if not, not removing the clock scene. By the method, the clock scene can be automatically removed according to a certain moment, and other predefined operations are awakened.

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 removing a clock in real time. Background technique [0002] In the online graphics and text packaging system, when the clock scene is played, sometimes the clock is used as a timer or countdown, and it needs to be removed at a certain time to wake up a new scene for playback. [0003] In the prior art, the real-time removal of the clock is mainly to observe the time through the operator's visual inspection. Once the time is found to reach a certain value, the clock scene is removed, and then a new scene is played. [0004] And in actual broadcasting, the main interface of the control layer controls the start time, end time, step size, etc. of the clock, but cannot know the actual precise time of each frame. If the main interface is used to compare the system time, if it is a countdown, the main int...
