3 Paolo Micanti Giuseppe Baruffa Fabrizio Frescura 2007 IEEE Mobile WiMAX Symposium Orlando, FL 120-124 25/03/2007 1-4244-0957-8 9485224 Digital Cinema, JPEG 2000, Reliable Multicast, WiMAX This paper presents a packetization strategy for the reliable electronic distribution of Digital Cinema (D-Cinema, DC) content. In particular, a reliable multicast protocol was used to send high definition video content to multiple receivers, allowing them to correctly receive the entire stream. The NORM protocol was chosen as multicast protocol, because of its guarantees on reliable transmission of both files and data. The target result is to send reliably DC contents, both using a single large file or a set of separate files. Applications in C++ were created to test our system. http://www.ieee-mobilewimax.org/
