Transmitting Scalable Mpeg-2 Video Over Atm Based Networks
INTEGRATION ISSUES IN LARGE COMMERCIAL MEDIA DELIVERY SYSTEMS(1996)
摘要
For high-end real-time video services, a prioritized transmission scheme (PT) should match the video information distribution of the high priority and low priority bitstreams generated by a layered source coder. This paper studies two PT schemes, which are respectively coupled- concatenated transmission (CCT) and coupled-interlaced transmission (CIT). Simulation results reveal that: given the same amount of network resource, the CIT scheme outperforms both the CCT scheme and the non-layered scheme in terms of the delivered video quality and the network resource utilization.
