Title:
音声信号と映像信号を同期させる装置
Document Type and Number:
Japanese Patent JP4382736
Kind Code:
B2
Abstract:
A receiver (FIGURE 2) for decoding associated compressed video and audio information components transmitted in mutually exclusive "frames" of data with respective time stamps PTSvid and PTSaud respectively, includes a controller (216) which is responsive to the respective received time stamps to provide coarse synchronization by delaying or skipping respective frames of one or the other of the components to approximately time align the two components. Fine synchronization is provided by adjusting the processing or clock frequency (215) of the audio signal processor (212) independent of the video processor(214). The control for the frequency adjustment is related to the difference between audio and video time stamps.
