The invention provides a sound and picture homology method and device, projection equipment and a readable storage medium, and relates to the field of projection. According to the invention, the method comprises the steps of: when sound and picture homology is needed, acquiring a calibration audio signal and adjusting the calibration audio signal to be in a pre-playing state; and then sending thepre-played calibration audio signal is sent to the audio playing device for playing, collecting a calibration audio signal played by the audio playing equipment; further, according to an audio sendingtime point and an audio acquisition time point of the projection equipment for the calibration audio signal, calculating audio transmission time consumption between the projection equipment and the audio playing equipment, then, reducing system processing time consumption for adjusting the audio signal state by combining projection equipment, and determining the audio playing time delay of the projection equipment in executing the audio playing operation; and finally, playing the to-be-projected video frame and the to-be-played audio frame in the same tone according to the audio playing timedelay, so that the audio and video synchronous playing effect is effectively improved, and the audio-visual experience of a user is ensured.
Description
technical field [0001] The present application relates to the field of projection, and in particular, to an audio-picture coherence method, device, projection equipment, and readable storage medium. Background technique [0002] With the continuous development of science and technology, the application of projection equipment is becoming more and more extensive, and it is usually necessary to play audio and video to meet the needs of different users. In the process of audio and video playback, it is often required that the audio signal played by the audio playback device and the video picture projected by the projection device match synchronously, so as to meet the audio-visual needs of users. [0003] At present, the audio and video synchronous playback scheme commonly adopted in the market is to directly adjust the audio signal and video signal to play at the same time point, in order to achieve the effect of audio and video synchronization. However, this audio-video sync...
