Abstract

Upgrading strategies are investigated for application in future super-broadband subscriber loops, where such technologies as super-multi-channel distribution, super- high-definition pictures, super large capacity storage and all-optical transport are expected to become available. Gradual upgrading is considered so that future systems can keep compatibility with existing systems. First, time frame and strategies for subscriber loop upgrade are overviewed and assumptions for evolution of broadband multimedia distribution systems are discussed. Next, upgrading strategies for broadband multimedia distribution are overviewed to discuss new schemes for representing super-high-definition (SHD) video channels and to show that considerably large number of additional channel counts can be required when upgradability and compatibility are taken into consideration. Finally, optimization of above mentioned upgradable and compatible super-multimedia distribution schemes is investigated.
