Intelligent Video Synthesis Using Virtual Video Prescriptions

To facilitate maximum reuse of video data, well-specified and systematic methods are required for the incorporation of digital video components into multiple delivery products. This paper presents an approach to the intelligent synthesis of digital video products by the representation of virtual videos using SGML. Virtual videos are defined using a Virtual Video Prescription to specify a generic model of a video production that includes embedded queries for the dynamic retrieval of video content from underlying databases. A detailed example is presented to demonstrate the prescription language syntax and its underlying concepts.
