Method and system for positioning synchronous video monitoring image of service process

This invention discloses a locating method and a system for a service process synchronous video monitor image which sets up the image relation between key data and synchronous monitor image data of each service register when keeping each of its registers to find out its key data first based on the service information then to recall the synchronous monitor image information corresponding to it so as to re-locate and play it, which overcomes the shortcomings of poor location efficiency in the process of locating service information to the synchronous video monitor image since the service process subsystem is independent of its synchronous flow monitor subsystem.
