Abstract
AbstractDespite much research in the field of mobile multimedia, delivery of real—time—interactive video over noisy wireless channels remains a challenging problem. Two of the major issues in providing true end—to—end mobile multimedia capability are interoperability between platforms and networks and the poor performance of video compression algorithms in error—prone environments. This paper presents a method for prioritising data partitioned MPEG—4 video in a way suitable for transmission over a mobile network. The effectiveness of the technique is demonstrated by examining the performance when transmitted using the Real—Time Transport protocol over GPRS (General Packet Radio Service) data channels under varying channel conditions.
