DVD Player with Atomic Clock

As digital video disk players (DVDs) offer more and more features, they become increasingly difficult for their owners to use. One of the most valuable and frequently used features of a DVD player is a clock, yet thousands of owners do not know how to program the clock successfully. What is needed is a way to automatically set the time for DVD clocks.

The present invention is a DVD player 100 that includes an atomic clock 110. Atomic clocks are the official source of time for the U.S. Department of Defense and provide the standard of time for the United States. These clocks are maintained by the U.S. Navy, and provide time signals in a variety of formats, including radio signals (see for more information on atomic clocks). The present invention is calibrated to the national atomic clock in Colorado, which provides accurate time to 10 billionths of a second.

In operation, atomic clock 110 sends a radio signal to the national atomic clock in Colorado at set intervals, such as when the power is turned on. The signal that is returned automatically adjusts atomic clock 110 to the correct time.
