Abstract

All digital HDTV systems over different media such as terrestrial broadcast, satellite, and coaxial or fiber cable are being proposed, implemented and tested in several countries. This paper presents technical challenges faced by such systems. First, in order to conserve the scarce terrestrial spectrum, bandwidth compression is required. Even after compression, picture quality has to be perceptibly better than today's TV and the cost of decompression in the HDTV set has to be kept small. Secondly, digital HDTV has to be receivable by all the people receiving the broadcast of current TV and has to fit within the spaces left in the present spectrum allocation. Finally, digital HDTV has to support all the functionality that we have gotten used to with today's TV (e.g., videotape recorders). This paper reviews these technical challenges and proposes one solution that addresses these challenges.
