Abstract:
A method for multiplexing a stored digital video file and a stored digital audio file, or a combined video/audio file, where the stored video and audio files are sampled, recorded and digitized at a first frame rate, FR1, but where the multiplexing assumes a second frame rate, FR2, and where said multiplexing preserves the video and audio synchronization, comprising the steps of:storing said digital audio file with first control bits associated with said audio file which relate to a digitizing process having a value compliant with FR2,multiplying the value of said first control bits by FR2/FR1 forming second control bits,replacing said first control bits by said second control bits,notifying said multiplexing and where said audio control bits are located,multiplexing said stored digital video file and said stored digital audio file containing said second control bits.
