Embodiment Construction
[0026] TVs can receive signals in a variety of ways, such as cable, satellite, and the Internet. Then disassemble the signal into image part and audio part.
[0027] For the image part, the TV performs image quality processing on it, and then outputs it to the monitor. For the audio part, after the TV performs sound effect processing on it, it is output to the speaker.
[0028] The image quality processing process mainly includes: brightness, contrast, chroma, hue, sharpness, image noise reduction, dynamic contrast, gamma, color temperature, white balance, color correction, brightness dynamic range, motion picture compensation, etc. process. The sound effect processing process mainly includes DTS (Digital Theater System) sound effect, ATMOS (Dolby Atmos / X-DMAX, Dolby Atmos) sound effect, GEQ (Graphic Equalizer, Graphic Equalizer) processing, PEQ (Parametric Equalizer) , parametric equalizer) processing, etc.
[0029] Among them, the process of image quality processing take...

The audio-video synchronization implementation device, method, and computer-readable storage medium provided by the present disclosure include: a display, used to present video information according to an image signal; a speaker, used to play audio information corresponding to the video information according to an audio signal; a processor , is configured to: obtain the processing method corresponding to the initial image signal, and determine the image delay according to the processing method; wherein, the image signal is obtained by processing the initial image signal through the above processing method; set the audio playback parameters corresponding to the audio signal according to the image delay, to Synchronizes the video information presented by the display with the audio information played by the speakers. In the solution provided by the present disclosure, the image delay can be determined according to the processing method of the initial image signal, and then the timing of playing the audio signal can be controlled according to the image delay, so that the image signal and the audio signal can be played synchronously, avoiding the excessive processing of the initial image signal. It takes a long time, which leads to the problem that the two playbacks are out of sync.
Description
technical field [0001] The present disclosure relates to video processing technology, and in particular to a device, method and computer-readable storage medium for realizing audio-video synchronization. Background technique [0002] Currently, display devices such as television sets are common household appliances. The display device can receive various types of signals and play video, such as cable signals, satellite signals, analog signals, network signals, and the like. [0003] During video playback, the signal is parsed into two parts, image and audio. The display device processes the image and audio separately, the processed image signal is output to the display, and the processed audio signal is output to the speaker, so as to realize video playback. [0004] Among them, since the processing of the image part by the display device takes longer than the processing of the audio part, the output image of the display device is not synchronized with the audio.
