A Model-Based Analysis of Scalable Multiple Description Coding

Research output: Chapter in Book/Report/Conference proceedingConference paper

Abstract

This paper proposes a novel Rate-Distortion (R-D) model
for a generic Embedded Multiple Description Scalar
Quantizer (EMDSQ). The proposed model is experimentally
validated for several quantizer instantiations, showing
notable accuracy. Driven by the proposed model, a detailed
theoretical analysis of a general EMDSQ-based Multiple
Description Coding (MDC) system is carried out. In this
context, an optimized packet transmission strategy for a
scalable MDC system is theoretically investigated. The
analysis reveals important insights into the optimal overall
redundancy and average Signal-to-Noise-Ratio (SNR)
variations of the system. Our analysis, being independent of
the quantizer realization, allows for drawing valuable
conclusions on the theoretically achievable performance of
EMDSQ-based MDC systems.
