Abstract: A method and apparatus for managing source and derivative data is disclosed. Source data, typically image data, is centralized in a database and derivative data sets are formed from the source data. When it is desired to modify a derivative data, the source data can be accessed and modified to form a new derivative data set instead of modifying the already derived data set. In this way source data integrity is maintained. Derivative data sets are identified and tags are associated with new derivative images. The tag can be embedded in the derivative data or associated with the image as an attached element. The tag identifies information such as the server that generated the derivative image, the source image and any tasks or transformations that were applied to the source image to generate the derivative data. Users of source data can be given access to a central source data repository and access privileges can be assigned.

Abstract: A method for detecting high speed data received by a computer and for delaying displaying the receive data, thereby increase the microprocessor time devoted to receiving and storing the input data. Three parameters are utilized for determining when updating the display should be delayed because data input speed is high. First, if the input data is close to filling the computer's receive buffer, the data input speed is high. Second, if the data input port becomes idle, no more data is being input to the computer and the display may be updated. Third, if the display has not been updated recently, as indicated by a preset timer timing out, an update of the display is forced so that the user can verify that data is successfully being input. By varying and limiting the number of display updates, the microprocessor is allocated more time to store and process received data when the data input speed demands.
