The authors present novel schemes for optimal OFDMA bit-rate allocation towards video quality maximization in H.264 Scalable Video Coding (SVC)-based 4G wireless systems. They use the rate and quality models for video characterization of the SVC extension of the H.264/AVC and develop the framework for optimal scalable video transmission. Subsequently, they derive the closed form solution of the optimal H.264 scalable video quantization parameter for sum video quality maximization in unicast and multicast 4G WiMAX Adaptive Modulation and Coding (AMC) scenarios. They also formulate a Vickrey-Clarke-Groves (VCG) auction-based Time-Frequency (TF) resource pricing scheme for dynamic bit-rate allocation and simultaneous prevention of video quality degradation by malicious users for H.264-based scalable video transmission.
