  • Methods for reserving index memory space in AVI recording apparatus
    Patent number: 8230125
    Abstract: A method for reserving memory space for storing chunk sizes during Audio Video Interleave (AVI) recording, wherein an AVI file contains a plurality of interleaved audio-video (A/V) chunks, includes: recording the AVI file sizes to the second storage; when the second storage reaches capacity, moving at least a first A/V chunk size to the first storage; and after the recording has finished, reading stored A/V chunks from the first storage to the second storage to create an index chunk.
    Type: Grant

  • METHOD FOR SYNCHRONZING AUDIO AND VIDEO DATA IN AVI FILE
    Publication number: 20090103897
    Abstract: A method for synchronizing audio and video data in an Audio Video Interleave (AVI) file, the AVI file containing a plurality of audio and video chunks, includes: determining a frame rate error of a group of consecutive main access units (GMAU) according to a video clock and an audio clock; determining a GMAU presentation time stamp (PTS) according to the frame rate error; and updating the AVI file with the GMAU PTS, so the GMAU will be played utilizing the GMAU PTS.
