Abstract
Techniques for receiving information during multimedia presentations and for communicating the received information to one or more information access devices. A presentation recorder adapter receives information during a multimedia presentation and communicates the information to access devices. The adapter may receive multimedia presentation information, comprising video information and audio information, from a first source. The adapter may also receive information from a second source separate from the first source during the multimedia presentation. For example, the second source may be an attendee of the multimedia presentation. The adapter may transmit the multimedia presentation information received from the first source and the information received from the second source to one or more information access devices.
