Abstract: A method for managing a computer simulation is disclosed. The method includes providing an interface for soliciting input of initialization parameters for generating a training exercise and receiving from the interface initialization parameters entered by a user. The method further includes executing the training exercise defined by the initialization parameters and providing a second interface for soliciting input of execution parameters for managing execution of the training exercise. The method further includes receiving from the second interface execution parameters entered by a user and modifying execution of the training exercise as defined by the execution parameters. The method further includes storing performance data associated with performance of participants during execution of the training exercise and providing a third interface that provides a summary of the performance data.

Abstract: An interactive image data transmission system uses the expertise of an image end user distant from the image collection point. An image with a wide angle field of view is transmitted to the end user in lossy-compressed form. The image is displayed at the receiving end with errors introduced by the lossy compression. The end user can select and specify a narrowed field of view, and the image capturing parameters are modified as necessary under end user control to capture a desired image of the narrow view field. The transmitting station transmits a lossy compressed version of the narrow view image which is displayed for the user, and the user selects at least one window of definite interest within the image. Then, additional image data sufficient to provide a correct display within the window(s) of interest is transmitted to the receiving station and the display is updated within the window(s). The additional data may be difference data in a variable length diagonal code.
