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 broadband video channels. Finally, optimization of upgrading is investigated in terms of rotatable display schemes.
