Abstract: A method and system for minimizing loss of critical digital data while such data is being written to a storage medium. The critical digital data is written to a digital storage medium in small blocks or segments. As each segment is transferred to the storage medium, the file allocation table is updated and the file is closed. By segmenting the files into smaller file segments, the amount of critical data lost as a result of a system failure or power loss is reduced. During playback, the file segments are dynamically assembled allowing playback of the digital data in a continuous manner.

Abstract: The present invention relates to a digital video recording system for use on an aircraft. The digital video recording system is configured with the same form factor as an analog video recording system to enable a direct hardware replacement. In addition the digital video recording system in accordance with the present invention is configured to emulate all of the functions of an analog video recording system including the ability to overwrite the existing data. By emulating the functions of an analog video recording system, aircraft which include cockpit controls for an analog video recording system can be reused with the newer digital video recording system. As such replacement of analog video recording systems is virtually seamless and does not require pilot training.
