Abstract
A process and system for synchronizing a video signal to the sampling period of a client system. The synchronization may be suitably implemented by adding or deleting trailing lines from each frame of video data to adjust the frame to match the sampling period of the client system. The synchronization system minimizes the lag between the time a video signal is delivered to the client system and the time the client system responds. The low lag time enhances the responsiveness of the client system to human inputs, and improves the suitability of the overall system to human use. The synchronization system can be achieved using suitable low-cost hardware and is therefore particularly well suited for video game or virtual reality systems designed for home use, increasing the feasibility of employing video inputs in such systems.
