ABSTRACT:
A synchronization process in an application program records audio fields with video synchronization counts, and plays back the audio and video fields in synchronism by tracking the video fields against the video sync counts in the audio fields. The video sync counts correspond to the number of video field processed when the audio field is processed. During recording of audio and video fields for the multimedia presentation, the video fields are counted. The video field count is appended to and recorded with each audio field. During playback, the system compares the count of video fields displayed against the video field count appended to the audio field being presented. If the counts are different, the system either skips video fields, or repeats video fields to bring the video fields into synchronism with the audio fields.
