On the Area Expected Distortion of Scalable Videos in Multi-Frequency System

Abstract

We investigate new performance analysis of multi-channel Scalable Video Coding (SVC) in multi-frequency system using Area Expected Distortion (AED). We begin by outlining the obtained explicit expression of AED in multi-frequency system namely fractional frequency reuse (FFR), for single layer and two-layer SVC. We start with mathematical model for single-layer and two-layered SVC, where expected distortion of the SVC that depends on the trade-off between the probability of outage and quantization accuracy is derived. The novel performance measurement of AED is then used to measure the relationship between the average distortion rate, outage probability and channel allocation per area in multi-frequency systems. Analysis of AED for FFR shows that the two-layer SVC outperforms the single layer transmission with 60 percent lesser expected distortion at 20dB, and we deduced a system parameter for two layer SVC, that given minimum AED when the threshold distance is at 0.86km and 0.78km at 20dB and 0dB respectively. The analytical results are verified using the Monte Carlo simulations.
