  • Methods and systems for encoding real time multimedia data
    Patent number: 6674803
    Abstract: Methods and systems are provided for generating a real time multimedia data stream with accurate time stamps for decoding. Time stamps are provided which compensate for a difference between a video frame rate corresponding to a video frame within the real time multimedia data stream and the oscillator clock. The video frame is then stamped with the time stamp which compensates for the difference between the theoretical presentation time stamp corresponding to the video frame and the oscillator clock.
