Abstract

Aiming to realize "Single Source Multi-Use" of video content and the diffusion of HDTV materials to a diverse range of media, including networks and portable video devices, the research has progressed on making HDTV program production more efficient through the application of JPEG2000 video coding scheme with scalability (hierarchical picture features) using Wavelet transform. Elementary technology research led to the construction of a compact PC-based JPEG2000 HDTV codec , a software of Motion-JPEG2000 player and network client that allows simple screening of HDTV material on a general PC, and a JPEG2000 multicast transmission protocol for HDTV material sharing in a networked program production environment and for relay broadcasting transmission with reduced delay over IP network. It is also available to transmit fully digitalized 16 channels audio sources. A prototype system was also fabricated with the integrations of these elementary technologies. Integration of JPEG2000 scalability and a network environment makes it feasible for program producers to handle mainline HDTV material in a simple PC environment. The system's intra-field coding also contributes to more efficient processing in the preproduction stages, such as material gathering and editing. In addition, the system also activates urgent news reporting by way of broadband IP network owing to reduced transmission delay of the system.
