Digital Cinema Package Transmission over Wireless
Paolo Micanti, Fabrizio Frescura, Giuseppe Baruffa · 2008
In this paper we present a method for the quasi- reliable transfer of Digital Cinema (DC) content over packet- lossy IP networks, such as wireless networks. By employing the MXF (Material eXchange Format) encapsulation, reliable transmission of MXF keys backup, and compressed frames Forward Error Correction (FEC), we show that visual artifacts due to packet losses are virtually cancelled, and decoder crashes can be avoided. DC video content adopts JPEG 2000 for image coding; in this standard, an extension, called JPEG 2000 for Wireless (JPWL), is provided to combat codestream (i.e., compressed image) errors. For the PCM audio, a combination of FEC and error concealment provides no or minimum degradation.
