Telecommunication Systems Transmission Issues for HDTV
نویسندگان
چکیده
The transmission of digital HDTV signals on satellite channels in the 20-30 GHz band is studied with the aim of designing an Italian domestic satellite, both for the exchange of programs among production centers and for direct broadcasting to end-users. Previous work on the definition of the system architecture and of the payloads is first briefly summarized. The transmission impairments due to the interfered environment are then analyzed in detail and simulation studies are reported. The results confirm the choices made for the link budgets during the system configuration design. Experimental tests carried out both with laboratory simulators and with the Olympus European satellite are finally described.

The study and development of systems for higher quality television has seen tremendous growth in recent years. This has been motivated by the fact that existing television systems give inadequate picture quality, especially for viewing on large screen displays. The main impairments which have been identified an~ scanning artifacts (line stucture visibility and flicker), limited resolution, and ...
