Abstract

A method and an apparatus for assembling, editing and producing a production video cassette from a source video cassette without timing signal recorded thereon is disclosed. The source video cassette is initially dubbed onto a dub cassette with timing signals recorded thereon. The dub cassette is edited and assembled, using the timing signals recorded thereon. Using the sync count of the original source cassette, the timing signal of the desired video scence is correlated with the sync field count of the source video cassette. A production cassette is made from the source cassette without the timing signal. The present invention also discloses assembling, editing and viewing a video cassette having timing signals associate recorded thereon. The cassette recorder is operated on based upon the performance characteristics which were predetermined. The assembling and editing of each of the video cassettes is done to form the video production. The video production is then viewed by activating the search and playback capability of the video cassette recorder based upon the performance characteristics of the cassette recorder. Finally, an audio/video controller system is disclosed where a…
