Synchronization control method and system for dynamic seat based on audio matching

Abstract

The invention relates to a synchronization control method and system for a dynamic seat based on audio matching. The method comprises the following steps that an audio stream signal output by a play system is collected, audio matching calculation is carried out, and a movie name and a present play time node of a dynamic movie are obtained; a target motion data file corresponding to the movie name is retrieved, and according to the present play time node, target motion data corresponding to the present play time node is read synchronously; and the target motion data is analyzed, a motion control instruction is generated, and motion of the dynamic seat is controlled. The method enables that the play system is not limited, supports PC, DVD, TV, mobile equipment or VR equipment, and is simple and low in cost; and a dynamic seat control system is connected with the play system via an audio line, use is convenient, the adaptability is high, the synchronization effect is good, and operations including fast forward, pause and drag and drop are supported during movie playing.

Description

technical field [0001] The invention relates to the field of dynamic seat control, in particular to a method and system for synchronously controlling a dynamic seat based on audio matching. Background technique [0002] The dynamic seat can make actions such as tilting and pitching according to the plot of the movie or the game scene. The various actions of the dynamic seat cooperate with the display screen to make the user feel present, thus creating a fully perceptual environment consistent with the content of the movie. In the existing technology, on the one hand, the synchronous control scheme of the dynamic seat realizes the synchronous control through the way that the playback system actively communicates with the seat controller, that is, the playback system needs to send a synchronization signal to the dynamic seat, and needs to transfer the motion data Send it to the dynamic seat controller in real time, and then the dynamic seat controller controls the motor action...

AI Technical Summary

Problems solved by technology

But the defect of this method is: the amount of motion data is large, and the transmission of motion data takes a long time, resulting in a time delay between the motion of the dynamic seat and the storyline of the movie being shown, that is, causing the motion of the dynamic seat to be delayed. Chair movements are poorly synchronized with the storyline of the film being shown

On the other hand, in the home theater, since the playback systems of different families are different, whether using PCs, DVDs, TVs, or mobile devices or VR devices, there is a problem of synchronizing with the dynamic seat control system. The playback system is limited, and dynamic seats are difficult to promote in home theaters
