Abstract

The invention relates to one kind of televisions and its regulating method, which can automatically adjust the synchronization of the image and audio signals, then output the synchronized image and audio signals. The television includes a control unit which is used to control the synchronization about the video signals from imaging processor and the audio signals from audio processor, and a signal synchronizing unit which is used to detect a delay value of frame images offered by the video processor according to the controlling of control unit, and to delay the frames of audio signals output from audio processor according to the above delay value in order to obtain an synchronized output of the image signals and audio signals.

Description

technical field [0001] The invention relates to a television receiver; in particular, it relates to a television receiver capable of automatically adjusting the synchronization of an image signal and an audio signal, and then outputting the synchronized image signal and audio signal and its adjusting method. Background technique [0002] With the rapid development of technologies such as electricity, electronics, computers, and communications, the field of multimedia, which synthesizes various forms of information including images or sounds, has also achieved tremendous development. In the process of rapid development of information and communication, in today's era known as the digital revolution, the form of information storage and existence is transitioning from analog to digital. Images require relatively large amounts of information; with the development of the dynamic image compression standard MPEG (Moving Picture Experts Group) technology used to compress digital ima...
