1. A method of recording information during a multimedia presentation, comprising:
- receiving information from a first source, the information received from the first source comprising video information generated from a presentation file;
receiving information from a second source separate from the first source during the multimedia presentation;
processing the information received from the first source and the information received from the second source to generate a first representation;
storing the first representation; and
providing access to the first representation via a first interface, wherein the first interface is selectable from a group of interfaces comprising a telephone interface, a serial interface using a modem, and a network interface, wherein processing the information received from the first source and the information received from the second source comprises;
selecting a plurality of video frames from the video information received from the first source, synchronizing the plurality of video frames with the information received from the second source, extracting textual information from the video information received from the first source using an optical character recognition technique, and extracting textual information from the information received from the second source using a voice recognition technique.

Abstract
Techniques for capturing information during multimedia presentations. According to an embodiment, the presentation recording appliance (PRA) receives multimedia presentation information comprising video information and/or audio information. The PRA may also receive information from external sources other than the first source. The audio and video information received by the PRA is then processed and stored in a format which facilitates subsequent retrieval.
