Data processing apparatus and method

摘要

Video presentation timing can match sounding timing with high accuracy. A digital broadcast receiver calculates the presentation delay time dt from the presentation time when video based on the compressed video data is to be presented to the time when the video is presented on the presentation unit, and outputs audio based on the compressed audio data when the calculated presentation delay time dt passes from the sounding time when the audio based on the compressed audio data is to be outputted.
