Abstract:
A method for storing uninterrupted digital video streams comprising the steps of:generating a digital video stream with a digital video capture device; compressing said digital video stream at a first compression ratio; directing said compressed digital video stream to a memory system for writing said compressed digital video stream, said memory system being operationally connected to said digital video capture device, said memory system and said digital video capture device being connected to move in combination relative to a surrounding environment; monitoring acceleration of said memory system relative to said surrounding environment; and adjusting said compression of said digital video stream to a second compression ratio in response to said detecting a preselected condition related to acceleration of said memory system; said compression adjusting including: (1) temporarily suspending writing operations by said memory system in response to detecting that an acceleration threshold has been exceeded; (2) measuring an amount of time that writing to said memory system is temporarily suspended because said acceleration threshold has been exceeded; and (3) setting said second compression ratio at a value that is based upon said measured amount of time.
