Técnicas para Sistemas de Vídeo sob Demanda Escaláveis

Carlo Kleber da S. RodriguesRosa Maria Meri Leão

This work introduces the novel bandwidth sharing technique denoted as Interactive Merge - MI as well as presents a thorough competitive analysis of the most recent proposals. Through simulations in different scenarios we note for instance that (i) the HSM paradigm is the most efficient one; (ii) the Patching paradigm presents the smallest system complexity and, for a service with small discontinuities, has an attractive competitiveness; (iii) the MI technique is the most efficient and, comparing to the classical Patching scheme, provides bandwidth and peak reductions of 30%-68% and 18%-62%, respectively.
