Settings and the setting structure: the description and automated propagation of networks for perusing videodisk image states

摘要

This paper describes a system for formally representing spatial relationships between videodisc image states called settings. A number of setting relations are defined, these being based on the manipulations of the camera typically used in the production of the moving film: zooming in or out, panning etc.. An algorithm is presented which, given a limited level of initial specification by a describer, will constrain, where possible, the setting relations holding between all pairs of settings. The resulting network is called the settings structure. The paper begins by placing the settings structure into the context of its being one part of the CLORIS system.
