Rate Partitioning for Optimal Quantization Parameter Selection in H.264 (SVC) Based 4G Broadcast/Multicast Wireless Video Communication
In this paper, the authors present a novel scheme for video quality maximization in the context of H.264 Scalable Video Coding (SVC) based 4G wireless broadcast and multicast video transmission. A typical wireless multicast group comprises of multimedia clients with varying wireless link qualities. Thus, the conventional Fair Rate Static Video (FRSV) transmission scheme, which aims to achieve QoS fairness in multicast video transmission is rate and hence quality constrained by the BMG subscriber with the worst link capacity. Hence, they propose a novel Rate Partitioning based Scalable Video (RPSV) transmission framework to overcome this limitation. The proposed RPSV scheme optimally partitions the multicast group for transmission of the H.264 coded base and enhancement scalable video layers.
