Abstract
A method for automatically recording snapshots of a computer screen during a computer session for later playback, comprises receiving a start indication, and automatically recording snapshots of a computer screen periodically during the computer session after the start indication is reached. An apparatus for performing such function comprises a frame buffer for storing snapshots of the computer screen, a FIFO cache memory, a mass storage memory, and programmed means. The programmed means receives a start indication, periodically copies data from the frame buffer to the FIFO cache memory during a computer session after the start indication is reached, and compresses the stored data before storing it the mass storage memory for later playback.
