In this short paper, a DVS (Delayed Video System) using a video camera and a personal computer is introduced. Using the personal computer's RAM as a frame buffer, DVS displays video images that were taken a few second before on the computer's display continuously. DVS could be useful for sports coaching or self training situations since it can provide visual feedback within a few seconds. DVS also provides a new func-tion, post triggered recording, which allows an event to be recorded after it has occurred.
