Abstract :
Variable bit rate (VBR) video traffic exhibits high rate variability, so smoothing algorithms are proposed to smooth video traffic using some cost functions. However, the relationship between cost functions and smoothing performance is not clear. To address this problem, this Letter examines the impact of cost functions on wavelet-based VBR video traffic smoothing (WTS) performance.
