CONTROLLING DIGITAL AUDIO/VIDEO SEGMENT DURATION WITH REMAPPED TIME CODE

摘要

Methods and systems are provided for time altering one or more discrete digital audio/video program segments, each program segment having distinct In time and Out time code points. Data from the digital program segments are received from a data source and decoded. The decoded data are modulated as a serial data stream. The modulated decoded data are provided to a time altering processor to remove or duplicate frame positions to time alter the frame sequence. The resulting time altered serial data stream is demodulated to provide buffered program segment data. The buffered and time altered program segments are encoded and provided in a desired file or streaming format. Audio synchronization with the video is maintained by duplication or removal of audio samples corresponding to the duplicated or removed video frames.
