Abstract From the Canadian patent

An interactive processor-controlled system for entering and storing user information about an event that is being concurrently recorded in real time correlates the user information to user-requested addresses such as time, values stored with the recorded signals. The system includes a recording device for producing signals indicating recorded event data that includes periodic addresses, each of which indicates a portion of the recorded signals.
