A Specification Language for Dynamic Virtual Video Sequence Generation
Abstract
The FRAMES project is developing a system for video database search, content-based retrieval, and virtual video program synthesis. For dynamic synthesis applications, a video program is specified at a high level using a virtual video prescription. The prescription is a document expressed in a semi-formal language specifying the video structure, including formal specifications for direct reference to specific video components, components specified and retrieved by parametric query, and components generated as associative chains based upon an initial specification. This paper describes the syntax and semantics of the specification language for associative chaining. The language allows the specification of entity types for association generation, the specification of conjunctions and disjunctions of entity types, initial values, fixed constraints, and weights upon entity types. A short example is presented to illustrate the use of the language and how it may be used to generate different video sequences from a common database of video components.
