  • Audio and video synchronizing method in transcoding system
    Patent number: 8509301
    Abstract: Provided is an audio and video synchronizing method in a transcoding system, which compensates for lossy audio frames and lossy video frames according to a relative time at an early encoding stage, corrects a jitter of audio frames and readjusts a jitter of video frames in order to correspond to the audio frames having the corrected jitter at a multiplexing stage that is a later encoding stage, thereby minimizing a variation of the duration of the video frames and preventing audio and video from being unsynchronized when a media file is reproduced.
