Reliable D-Cinema Multicasting over Heterogeneous Networks

Authors: Paolo Micanti, Giuseppe Baruffa, and Fabrizio Frescura Title: Reliable D-Cinema Multicasting over Heterogeneous Networks Journal: JOURNAL OF COMMUNICATIONS (In Press) DOI: http://dx.doi.org/ Abstract: This paper presents a packetization strategy for the reliable electronic distribution of Digital Cinema (D-Cinema, DC) content. In this paper, new experimental results and design improvements are introduced, with respect to those presented in [1]. A reliable multicast protocol was used to send high definition DC video contents to multiple receivers, allowing them to correctly acquire the entire stream. NORM (NACK Oriented Reliable Multicast) was chosen as multicast protocol, because of the guarantees offered on the reliable transmission of data. The target result is to send reliably DC contents, by exploiting a number of multicast-enabled heterogeneous networks, such as fiber, satellite, WiMAX, etc. The results show that a reasonable transfer speed may be achieved even in presence of low transmission bandwidth and moderate packet loss rate.
