Description

Live broadcast intelligent switching device Technical Field The utility model relates to the technical field of picture special effect switching stations, in particular to a live broadcast intelligent switching device. Background In the current era of rapid development of digital media, the live broadcasting industry is vigorous, a picture special effect switching table is used as an indispensable key device in the live broadcasting process, the operation performance of the picture special effect switching table has a critical influence on the quality and effect of live broadcasting, a traditional picture special effect switching table mainly depends on manual operation, an operator needs to consider a plurality of function keys, push rods and knobs simultaneously in the live broadcasting process to realize picture switching and special effect adjustment, for example, in a comprehensive live broadcasting activity, frequent switching of a plurality of picture sources and timely application of various special effects (such as fade-in fade-out, image drawing, rotation, scaling and the like) can be involved, the operator needs to keep high concentration all the time, the operator needs to manually press the corresponding keys to select pictures, push and pull the push rods to control the transition degree of the special effects, and the knob is rotated to adjust parameters (such as brightness, contrast, color saturation) of the pictures and parameters (such as speed, intensity and the like) of the special effects. However, the manual operation mode has various defects, on one hand, along with the increasing richness and complexity of live broadcast contents, the operation flow becomes extremely complicated, operators need to continuously switch among different operation parts, the operation speed is greatly reduced, the requirements on quick and accurate switching of pictures in the fast-paced live broadcast process are difficult to meet, on the other hand, long-time manual operation easily causes fatigue and mental tension to the operators, so that misoperation is frequently caused, such as wrong pressing of keys, inaccurate pushing amplitude of push rods, deviation of rotating angles of knobs and the like, the errors possibly cause problems of blocking, uncoordinated special effects, abrupt change of picture quality and the like of live broadcast pictures, the smoothness and ornamental value of live broadcast are seriously influenced, even the whole effect of live broadcast is possibly negatively influenced, the watching experience and satisfaction of the audience are reduced, and the commercial value and the propagation effect of live broadcast activities are further influenced. Disclosure of utility model The utility model aims to solve the problem that a picture special effect switching table in the prior art mainly depends on manual operation, and provides a live broadcast intelligent switching device.
