A Program Production System Using ID and File-Data over IP Networks

This paper proposes a program production system over an IP network that uses and integrates Unique Material Identifier (UMID), Material eXchange Format (MXF), and non-destructive editing, based on the editing description. In this system, materials and their metadata on distributed servers can be accessed from anywhere on the network by attaching a UMID to all materials and by wrapping the UMID, metadata, and materials in MXF format The result of editing is output in the form of an editing description, and all materials are referred to by the UMID in the editing description. In broadcasting, or completing the program, the video reproduction equipment searches the original source material by the UMID and processes materials with effects according to the editing description. Images to be superimposed can be created in parallel while editing the program, by notifying the program producer application of the UMID only. The system has been implemented experimentally, its operation has been verified, and its effectiveness confirmed.
