Abstract
Official abstract text for this publication.
An audio-video synchronization detection device and a method thereof are provided. The audio-video synchronization detection device detects an object under test which is capable of generating an image signal and an audio signal. The audio-video synchronization detection device includes a delay circuit, an optical sensor, and a signal processor. The delay circuit delays the audio signal for a predetermined time and generates an audio correction signal accordingly. The optical sensor senses a light emitted by a display panel when the display panel displays the image signal and generates an image sensing signal accordingly. The signal processor calculates a delay time between the audio correction signal and the image sensing signal to obtain a synchronization state between the image signal and the audio signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An audio-video synchronization detection device, for detecting an object under test, wherein the object under test is capable of generating an image signal and an audio signal, and the audio-video synchronization detection device is electrically connected to the object under test to receive the image signal and the audio signal, the audio-video synchronization detection device comprising: a delay circuit, adapted to delay the audio signal for a predetermined…
