ABSTRACT:
A variable speed film transport interlock control system for allowing a plurality of film audio elements to be run in synchronization with each other with at least one film element running at a different selected speed than the other elements. The system generates a modified drive signal from a standard system drive signal such that the modified signal corresponds to a speed with a fixed ratio to the speed of the standard drive signal under all operating conditions. This permits the modified signal to drive a film transport device, such as a recorder or reproducer, at a different speed than the other transport devices while maintaining synchronization with the other devices during forward or reverse, stopping and starting, high speed or low speed operation.
