Development of JPEG2000 HDTV Program Production System

Aiming to realize "single source multi-use" of HDTV materials to a diverse range of media, our research has progressed on making HDTV program production more efficient through the application of JPEG2000 ("JP2K" for short) video coding scheme with scalability by wavelet transform. Elementary technology research led to the construction of a compact PC-based JP2K HDTV codec, a software of motion-JP2K player and network client that allows simple screening of HDTV material on a general PC, and a JP2K multicast transmission protocol for HDTV material sharing in a networked program production environment and for relay transmission with reduced delay over IP network. A prototype system fabricated makes it feasible for program producers to handle mainline HDTV material in a simple PC and network environment. Experimental results of coding performance and transmission performance of the protocol are also reported.
