MULTIPLEXING DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multiplexing device and a method which will not cause a step-out even when at least one of plural input signals has jitters or an input signal has disturbance. SOLUTION: A controller 6 calculates a time (time stamp) to start the reproduction or decoding of video data based on a time interval including a fluctuation component that is caused by jitters between AUs(access units) from a video encoder 3 and also on the identification information (input frame numbers) on these AUs. A multiplexed 7 adds the above time stamp calculated by the controller 6 to each AU and then multiplexes the time stamp of the AU with the AU from an audio encoder 5.
