ABSTRACT:
A video and audio editing system which eliminates failures in the fetching of video or audio data. The video and audio editing system also accounts for the silence which occurs at the top of audio data and the problems which arise when compressed video and audio data are reproduced simultaneously but not synchronously. The system includes a start time table and an end time table for storing a processing start time and a processing end time, respectively, for each scene to be fetched, a time lag inputting apparatus for inputting time lags in fetching of an external apparatus and an audio board, a table updating apparatus for updating contents of the start and end time tables based on the inputted time lags, and a controller for referring to the contents of the start and end time tables to control fetching start and end times of video data and audio data or control reading start and end times from the storage medium and fetching or reading out the audio data skipping silence data corresponding to the time lags.
