Compliant multimedia data multiple distribution in mobile networks


As an accepted solution to the mobile network heterogeneity problem, the layered multiple distribution enquires data layering and subscriber join-experiments that cost amount of resources. So, it is limited in heterogeneous mobile network environments. This paper first proposes a novel adaptive stream multiple distribution for MPEG-4 FGS video to meet these challenges. Based on the fine-granularity property of MPEG-4 FGS video coding technology, the scheme tries to delivery multimedia multiple distribution service over the heterogeneous networks in a similar way as that to transport water in pipelines, where the valves in pipelines adjust water flux to next pipeline. A modified method of computing PSNR, which considered the dependence of frames in one GOP, is used to evaluate the MPEG-4 FGS video transmission. Simulated results indicate that the scheme could dispose the heterogeneity of networks and end-systems freely, with permanent stability, flexible scalability
