The present application discloses an audio-video synchronization
processing method and a
display device. The
display device includes a first
chip and a second
chip, the first
chip is provided with a first video processor, a first audio processor and a controller, and the second chip is provided with a The second video processor and the second audio processor; the second video processor obtains the time-consuming
processing of the second
image quality, and the second audio processor obtains the time-consuming
processing of the
second sound; the first video processor obtains the first
image quality processing Time-consuming; the first audio processor obtains the first sound processing time; the controller calculates according to the first
image quality processing time, the second image quality processing time, the first sound processing time, and the
second sound processing time Audio-video synchronization
time difference, judging whether the audio-video synchronization
time difference is within the threshold range, if not, performing synchronous compensation for the video
signal and
audio signal output by the second chip. This application can realize the synchronization of sound and picture, thereby improving the video playback effect of the
display device, especially this solution can be applied to social TV.
