Abstract
A system and method for recording a collaborative session includes two phases. One is performed in real-time and includes determining portions of a composite image of collaborative session content that are constant over time or preprocessed. The portions are removed from the composite image of the collaborative session content. Remaining content of the composite image and any of the portions not already compressed is compressed and stored. A second phase is performed when off-line and includes decoding the remaining content of the composite image and the portions to reconstruct the composite image of the collaborative session content and formatting the composite image.
