Real time user indexing of random access time stamp correlated databases
First Claim
1. A system for providing random access to a data set, preferably an audio and/or video data set, comprising:
- means, including a user interface, for capturing of said indicia hand generated by a user during a serial rendition of said data set so that each indicium is time correlated with a respective part of said data set, such indicia being available for subsequent selection by a user; and
means for indexing into said data set to identify the part thereof that is time correlated with any indicium a user selects from said indicia;
said system being characterized by including.means for automatically time-stamping each indicium upon its generation by the user, and means for automatically time-stamping the part of said data set with which said indicium is time correlated substantially concurrently with the time-stamping of said indicium, with all such time-stamping being referenced to a common time base;
means for automatically storing, retrieving and displaying said user-generated indicia; and
means for determining the time-stamp of each user-selected indicium for use by said indexing means;
said user interface being adapted for electronically both capturing and displaying said user generated indicia.

Abstract
A note-taking system based on a notepad computer with an integrated audio/video-recorder is described. A document is created or retrieved. As the user types on the keyboard or writes with the stylus or similar input instrument, each character or stroke that is input by the user is invisibly time-stamped by the computer. The audio/video stream is also continuously time-stamped during recording. To play a section of recording back, the user selects part of the note (perhaps by circling it with a stylus) and invokes a "playback selection" command. The computer then examines the time-stamp and "winds" the record to the corresponding place in the audio/video recording, where it starts playing--so that the user hears and/or sees what was being recorded at the instant the selected text or strokes were input. With a graphical user interface, the user may input key "topic" words and subsequently place check marks by the appropriate word as the conversation topic veers into that neighborhood.
